Wubi (ubuntu)

noreply@blogger.com (sumesh) — Mon, 24 Nov 2008 11:22:00 +0000

If you want to install ubuntu 7.04 Feisty, but you don't want to modify your Windows partition and you want to install it inside, http://wubi-installer.org/ is for you. According to its website:

Wubi is an unofficial Ubuntu installer for Windows users that will bring you into the Linux world with a few clicks. Wubi allows you to install and uninstall Ubuntu as any other application. If you heard about Linux and Ubuntu, if you wanted to try them but you were afraid, this is for you.

Moreover, Wubi doesn't need you to replace the default Windows bootloader, as "Wubi adds an entry to the Windows boot menu which allows you to run Linux. Ubuntu is installed within a file in the windows file system (c:\wubi\disks\system.virtual.disk), this file is seen by Linux as a real hard disk." Then it loads the file as a loopback root Filesystem, kind like those described in "The Loopback Root Filesystem HOWTO," but with the loopback filesystem is actually in Windows's partition.

Since Wubi makes Ubuntu run inside Windows partition, there will be a little bit performance penalty, especially when your Windows partition is fragmented. Moreover, if there were any error in the ntfs partition that affects the system virtual disk, you need to fix the errors with something like chkdsk in Windows first before booting Ubuntu. If you're not afraid of partitioning, I still recommend you to install Ubuntu in a separate partition.

Nokia 5800 Tube Xpressmedia

noreply@blogger.com (sumesh) — Wed, 08 Oct 2008 04:19:00 +0000

Nokia, the Finnish firm is a household name in mobile phones in India. Its touch screen phone is the latest but late entry into the phase

of such phones. But the company has a history of coming late to the market with innovations yet ends up successful. The main competitors now are Apple's iPhone and Android.

Carolina Milanesi, an analyst said to Reuters" The Phone is extremely important ........We have been waiting for the market leader to respond to Apple's iPhone for a year and a half now. There is a lot of pressure on Nokia".

Nokia will unveil the Nokia 5800 XpressMusic tomorrow (2nd Oct'08), otherwise known as the Nokia "Tube". There are no official details yet, but the phone is expected to include a 3.2in colour touchscreen, full internet browsing connectivity, a 3.2 mega-pixel camera and built-in GPS.

Other contenders in the smart-phone battle include T-Mobile's HTC G1. Also known as the "Google phone", it has advanced Android software with one-click access to Google search and e-mail, and GPS.

Apple's new 3G iPhone is considered by many to be the sexiest smart-phone and has a plethora of features accessed through it 3.5in touchscreen and virtual keyboard. It also has one-touch music downloads from the iTunes music store.

The Blackberry Storm will be the big Christmas offering from RIM and for the first time has a touchscreen. It should be in the shops by November. Expect all the usual push e-mail features and more.

However, the leaders of the mobile industry are charged up as ever and have predicted a 10% increase in supplying mobile devices this year as compared to 1.14 billion units in 2007.

The company claims to have acquired the S60 software developed by Symbian.The Latest touch screen will soon be available in European and other International markets.

The stocks of the company closed at $19.68, down by 3% on Friday.

All the super rich geeks, watch out for this decked out 24 karat gold MacBook Air with a decorated version of the classic rainbow Apple. Folks at Computerchoppers are ready to entice their filthy rich clients with the shiny gold and colored sapphire. Maybe you find it a little flashy at first but you will definitely start loving it. There is no obvious change in the weight expect for few ounces here and there. Air is a standard 1.6ghz/2gb/80GB, with a 24-karat gold plating, polished exterior, and flat/crystallite interior.

The price: $5000 USD. However you will have to chip in another 3000$ for the rainbow which is 14-karat gold with 3.8ctw sapphires.

Can't Log On to Windows XP?

noreply@blogger.com (sumesh) — Wed, 20 Aug 2008 11:40:00 +0000

Forgot Ur Administrator Password!

Forgot Ur Administrator Password!!!!!!

Can't Log On to Windows XP?

If that’s your only problem, then you probably have nothing to worry about. As long as you have your Windows XP CD, you can get back into your system using a simple but effective method made possible by a little known access hole in Windows XP.

you can easily change or wipe out your Administrator password for free during a Windows XP Repair. Here’s how with a step-by-step description of the initial Repair process included for newbie’s.

1. Place your Windows XP CD in your cd-rom and start your computer (it’s assumed here that your XP CD is bootable – as it should be - and that you have your bios set to boot from CD)

2. Keep your eye on the screen messages for booting to your cd Typically, it will be “Press any key to boot from cd”

3. Once you get in, the first screen will indicate that Setup is inspecting your system and loading files.

4. When you get to the Welcome to Setup screen, press ENTER to Setup Windows now

5. The Licensing Agreement comes next - Press F8 to accept it.

6. The next screen is the Setup screen which gives you the option to do a Repair. It should read something like “If one of the following Windows XP installations is damaged, Setup can try to repair it”

Use the up and down arrow keys to select your XP installation (if you only have one, it should already be selected) and press R to begin the Repair process.

7. Let the Repair run. Setup will now check your disks and then start copying files which can take several minutes.

8. Shortly after the Copying Files stage, you will be required to reboot. (this will happen automatically – you will see a progress bar stating “Your computer will reboot in 15 seconds”

9. During the reboot, do not make the mistake of “pressing any key” to boot from the CD again! Setup will resume automatically with the standard billboard screens and you will notice Installing Windows is highlighted.

10. Keep your eye on the lower left hand side of the screen and when you see the Installing Devices progress bar, press SHIFT + F10. This is the security hole! A command console will now open up giving you the potential for wide access to your system.

11. At the prompt, type NUSRMGR.CPL and press Enter. Voila! You have just gained graphical access to your User Accounts in the Control Panel.

12. Now simply pick the account you need to change and remove or change your password as you prefer. If you want to log on without having to enter your new password, you can type control userpasswords2 at the prompt and choose to log on without being asked for password. After you’ve made your changes close the windows, exit the command box and continue on with the Repair (have your Product key handy).

13. Once the Repair is done, you will be able to log on with your new password (or without a password if you chose not to use one or if you chose not to be asked for a password). Your programs and personalized settings should remain intact.

It has been tested on Windows XP Pro with and without SP1 and also has been used in a real situation where someone could not remember their password and it worked like a charm to fix the problem. This security hole allows access to more than just user accounts. You can also access the Registry and Policy Editor, for example. And its gui access with mouse control. Of course, a Product Key will be needed to continue with the Repair after making the changes, but for anyone intent on gaining access to your system, this would be no problem.

And in case you are wondering, NO, you cannot cancel install after making the changes and expect to logon with your new password.

Cancelling will just result in Setup resuming at bootup and your changes will be lost

MP3 embedding in blogs

noreply@blogger.com (sumesh) — Thu, 31 Jul 2008 11:37:00 +0000

You have an MP3 file (a podcast, a song of your band, a lecture) and you want to share it with the visitors of your site. You can just put a link to the MP3 and let people download it or you can include it as an object and let the browser play it with a plug-in like QuickTime (and most of the times also crash the browser). Most people want to preview the audio and not wait until it downloads completely. You can play a partial MP3 file in audio player, but many people aren't aware of that.

But there's another away: a Flash player that allows you to pause and rewind the MP3. It's like an audio version of Google Video or YouTube, with the difference that the file is hosted on your server (or on another server). While there are many solutions based on Flash, this is the one I like the most. It's a modified version of Odeo player, that's used to play podcasts on odeo.com:

You just have to replace [MP3 file address] with the actual address.

Here you can see how it looks (in this audio, Marissa Mayer talks about innovation at Google):

Adding battery meter in the program form

noreply@blogger.com (sumesh) — Tue, 15 Jul 2008 09:50:00 +0000

For adding a signal, blue tooth or battery gadget in our palm project

just add a gadget (width=16, height=12) to your form, and use the
HsStatusSetGadgetType API from the Palm/Treo SDK.

If you develop with HB++, here is a link to a project that demonstrate hwo to
add Network, battery and Bluetooth gadgets:

Add Scroll bar in the field

noreply@blogger.com (sumesh) — Fri, 11 Jul 2008 05:46:00 +0000

--------- 1: create these three functions ------------

// you need to replace 700 by the ID of your field, and 710 by the ID of your scrollbar !!!!

void updateScrollbar(void)
{
FormPtr frm = FrmGetActiveForm();
ScrollBarPtr scroll;
FieldPtr field;
Int16 currentPosition;
Int16 textHeight;
Int16 fieldHeight;
Int16 maxValue;
field = FrmGetObjectPtr(frm, FrmGetObjectIndex(frm, 700));
FldGetScrollValues(field, &currentPosition, &textHeight, &fieldHeight);

// if the field is 3 lines, and the text height is 4 lines
// then we can scroll so that the first line is at the top
// (scroll position 0) or so the second line is at the top
// (scroll postion 1). These two values are enough to see
// the entire text.

if (textHeight > fieldHeight)
maxValue = textHeight - fieldHeight;
else if (currentPosition)
maxValue = currentPosition;
else
maxValue = 0;

scroll = FrmGetObjectPtr(frm, FrmGetObjectIndex(frm, 710));
// on a page scroll, want to overlap by one line (to provide context)
SclSetScrollBar(scroll, currentPosition, 0, maxValue, fieldHeight - 1);
}

void scrollLines(Int16 numLinesToScroll, Boolean redraw)
{
FormPtr frm = FrmGetActiveForm();
FieldPtr field;
field = FrmGetObjectPtr(frm, FrmGetObjectIndex(frm, 700));
if (numLinesToScroll < class="qBody" id="EchoTopic">(field) && numLinesToScroll < frm =" FrmGetActiveForm();" field =" FrmGetObjectPtr(frm," linestoscroll =" FldGetVisibleLines(field)" direction ="=" linestoscroll =" -linesToScroll;"> true);
}
}

--------- 2: modify your main form handler like this ------------

where the event frmOpenEvent is caught, add this line *before* calling FrmDrawForm:

updateScrollbar();

add this code to catch the events fldChangedEvent and sclRepeatEvent:

case fldChangedEvent:
updateScrollbar();
handled = true;
break;

case sclRepeatEvent:
scrollLines(eventP->data.sclRepeat.newValue - eventP->data.sclRepeat.value, false);
break;

Getting RGBcolor value from picel value in palm

Determining PalmOS Make and Model at Run Time

noreply@blogger.com (sumesh) — Thu, 10 Apr 2008 05:27:00 +0000

Sometimes it's necessary to determine the actual manufacturer or model of the device your app is running on, at runtime. These cases are rare, since usually you want to determine the presence of a particular PalmOS feature, and there are APIs to do that. It's not straightforward to determine device type, because the technique has evolved over the life of the OS.

I derived this information experimentally, or by perusing header files, or by contributed observations from other developers. If it's wrong, blame me and not PalmSource or the licensees. The contradictions shown in this table are clear support for PalmSource's oft-repeated advice to use supported API's to query for particular capabilities (like color, VFS, wireless network) at runtime and not to depend on looking up the device model.

If you have information to add, please send it to me. You can extract information from your device like this:

UInt32 deviceID, companyID, miscFlags;

Err devErr, compErr, miscErr;

devErr = FtrGet(sysFtrCreator, sysFtrNumOEMDeviceID, &deviceID);

compErr = FtrGet(sysFtrCreator, sysFtrNumOEMCompanyID, &companyID);

miscErr = FtrGet(sysFtrCreator, sysFtrNumHwrMiscFlags, &miscFlags);

if (!compErr) WinDrawChars((Char *) &companyID, 4, 20, 30);

if (!devErr)

WinDrawChars((Char *) &deviceID, 4, 20, 45);

You'll have to look at the value of miscFlags as an integer, masking it with hwrMiscFlagIDMask. For Handspring devices you probably have to look at deviceID as an integer instead of 4 characters.

Or if you prefer, you can run the program pixelcheckD.prc and send me the results. If your device isn't in the table above, lend a hand and send me your info. Send me the Maker, Device, and the string printed below the pitch value. If you're really ambitious, measure the length of the line next to "2 cm" and tell me how long it really is. The solid square should be just large enough to contain a US quarter.

For the capabilities of particular devices, see http://www.palmos.com/dev/tech/hardware/compare.html or the individual manufacturers' web sites.

Vibrate palm device using HsIndicatorState

noreply@blogger.com (sumesh) — Wed, 26 Mar 2008 03:55:00 +0000

For Vibration alerts in palm devices we can use this function.

void Vibrate()
{

Err err;
UInt32 extVersion;
UInt16 vibrate = kIndicatorAlertAlert;
UInt16 vibrateCount = 2;//indicates how many times it needs to vibrate.

err = FtrGet(hsFtrCreator, hsFtrIDVersion, &extVersion);

if(err == errNone && extVersion >= 0x05000000) // actually could be 0x05210000
{

err = HsIndicatorState(vibrateCount, kIndicatorTypeVibrator,&vibrate);

}

SndPlaySystemSound (sndInfo);//For making one sound indication. Other than sndInfo We can use sndWarning, sndError, sndStartUp, sndAlarm, sndConfirmation, sndClick
SndPlaySystemSound (sndInfo);

}

The documentation for the HsIndicatorState

Err HsIndicatorState	(	UInt16	count,
		UInt16	indicatorType,
		UInt16 *	stateP
	)

Set or get the state of the LED or Vibrator.

Parameters:

	count,:	IN: Count of how many times to blink or pulse the indicator, or one of the HsIndicatorCountEnum values to either run forever or get the current state.
	indicatorType,:	IN: HsIndicatorTypeEnum (LED or vibrator)
	stateP,:	IN: Pointer to HsIndicatorStateEnum If setting, points to state to set. If getting, as IN param points to “none” state of the source to query (or kIndicatorStateNull to query whatever source has priority). As OUT param, contains the result of the query (kIndicatorStateNull if querying for the active source and there is none)

Return values:

Err

0 if no error

How to persist data on a Palm hand held

noreply@blogger.com (sumesh) — Wed, 19 Mar 2008 05:56:00 +0000

Introduction

Welcomed this, my third article on palm development. Now that we have covered the basics and can create an application with some GUI components, the next important thing is to be able to persist data. The palm application philosophy is simple. When an application is started, it should be in the State that it was last left, giving the illusion of a multithreaded system, were in fact only one thread can run at a time. In order for this to be possible, as well as in order for just about any useful application to be written, we need to store data. Because the palm has no external storage mediums, data is stored in memory, in area is known as databases. I am sorry to report that this is somewhat of a misnomer, and does not in any way imply facilities such as SQL or relational tables. Instead what you get is a block of memory which is associated with your creator ID and the name, from which you can select data by either its array style index, or an ID which is guaranteed to be unique in the context of that device, and which would have no relation to the ID returned if the same application were run on a different device.

Creating a database

The first step of course is to create a database. The variable which equates to a handle to a database is a DmOpenRef. You should declare one of these as a global in your main header file for each database that you need to keep open. The call to create a database looks like this.

Err err = 0;

err = DmCreateDatabase(0, "BugSquBugsDYTC", 'DYTC', 'DATA', false);

DYTC is my unique creator ID, it stands for Dytech, which is the name of my employer. You should have previously registered your own ID on the www.PalmOS.com web site, and you should substitute that as the third parameter. The first parameter represents the card number on which to create a database, and it is almost universally 0. The second parameter is a name for a database, you will note that I have used my creator ID within the name, which palm recommend doing in order to ensure that your database name is unique. The fourth parameter is the type of database, and can be any for character constant. You may not have noticed this, but in fact that creator ID AND the type are actually 32-bit numbers, which are generated from the four 8-bit char values which we provide. In theory one could create a number of databases for an application which have the same name, and differ by type. However, in my experience, I have found that unless the type is DATA, your data base will appear within the palm as a file separate from your application, which I regard as undesirable. The final parameter is a ball in value, which specifies if this is a resource database. For our purposes, we will only be creating record databases, therefore this parameter will always be false.

Opening a database

At this point, we still do not have an open database and we have not used our DmOpenRef. We're now going to correct both of these anomalies. There are two ways to open a database. The first is as follows:

DmOpenRef myRef;

DmOpenDatabaseByTypeCreator('DATA' , 'DYTC', dmModeReadWrite);

The parameters are the database type, the creator ID, and the mode in which to open the database. This seems to be the wide almost universally preferred by both the official palm documentation, and the third party books that I read. Why this is so is a mystery to me, because it does not use the name which we have so carefully crafted to be unique for this particular device, and instead requires that we either register a creator ID for every database we want to create, or that we create databases with arbitrary types of our own invention, and as a result (at least in my experience) have databases which our users can delete apart from application. The method which I prefer is a little more long-winded, but I believe it is superior nonetheless. It looks something like this:

Err err = 0;

LocalID dbID = DmFindDatabase(0,"BugSquBugsDYTC");

gDB = NULL;

if (dbID > 0) gDB = DmOpenDatabase(0, dbID, dmModeReadWrite);

if (!gDB)

 err = DmCreateDatabase(0, "BugSquBugsDYTC", 'DYTC', 'DATA', false);

   if (err == 0)

  gDB = DmOpenDatabase(0, DmFindDatabase(0,"BugSquBugsDYTC"), dmModeReadWrite);

The first API call we make it is DmFindDatabase, which takes the card number and the database name and returns a LocalID, which I presume to be a 32-bit number, on the basis that when I first tried it by used a UInt16 and it did not work. This ID when it is returned can be passed to DmOpenDatabase, which takes the card number again,our LocalID, and the open mode required. If it fails, the return value is null and so we continue to create our database both in the distance where it cannot be found, and where it cannot be opened. Assuming the database is successfully created, we then open it. Note that we need to call find database again, as the value returned the first time was invalid, all we would have not reached this point.

Creating records

So at this point we have a database on a palm, and a handle to it. Quite obviously the next step is to create some data records with the database, in particular it is likely that our newly created database should have some default values within it. The sample application is called Bug Squasher. It was written as a learning exercise, and in theory is designed to be part of a bug tracking system, where the desktop system updates a list of applications which can have bug reports, and the Palm creates bug reports which can then be uploaded to the main system. The simpler of the two databases simply stores a list of names, which equate to projects for which we can report bugs. The two default values are 'misc' ( for bugs on systems not in the Palm ) and 'BugSqu' ( so we can report bugs on the bug tracking system itself ). The functions we will need to create a record and fill it with data are DmNewRecord, which takes three parameters ( the database to operate on, the index of the record to create, and a length for the record ), and DmStrCopy, which takes a Char * ( derived from our record handle, as we will see ), a start position, and another Char *, which we will copy. Note that I capitalise the word Char, this is a common way for PalmOS to create it's own types, a Char is the type used by Palm, as opposed to char. That they are the same thing is immaterial, Palm create their own types to ensure all types are the same size across platforms. The other functions we will use are MemHandleLock, which returns a void *, and which we call on our new database record, casting the result to a Char *. Finally, MemPtrNew is the Palm equivelant of malloc, and is used to create our string, StrCopy is the equivelant of strcpy and is used to place a value in our string, and MemPtrFree is used to free the string we created. Here is the code:

Collapse

UInt16 index = dmMaxRecordIndex;

MemHandle h = DmNewRecord(gDBProj, &index, 5);

if (!h)

    err = DmGetLastErr();

else

    Char * s = (Char *) MemHandleLock(h);

    Char * pChar = (Char*)MemPtrNew(5 * sizeof(Char*));

    StrCopy(pChar, "Misc\0");

    DmStrCopy(s, 0, pChar);

MemPtrFree( pChar);

    MemHandleUnlock(h);

index = dmMaxRecordIndex;

h = DmNewRecord(gDBProj, &index, 6);

if (!h)

    err = DmGetLastErr();

else

 Char * s = (Char *) MemHandleLock(h);

    Char * pChar = (Char*)MemPtrNew(6 * sizeof(Char*));

    StrCopy(pChar, "BugSq\0");

    DmStrCopy(s, 0, pChar);

MemPtrFree( pChar);

    MemHandleUnlock(h);

dmMaxRecordIndex is a Palm defined constant which causes our record to be created at the end of the database. Note we need to set it twice, as when we pass it into DmNewRecord, it is set to be the actual index of the created record. It's not shown here, but DmReleaseRecord should be called to release the record as soon as it is no longer needed.

Well, that was easy, wasn't it ? But because the databases are just an area of memory and offer no real facilities beyond locking a record in terms of accessing items within a record, what do we do when we want to store more complex data ? The answer is to create a struct that defines our datatype. For example, if we had a strict that looks like this:

typedef struct {

  DateType DateEntered;

  UInt8 nBugSeverity;

  UInt8 nBugType;

} BugRecord;

then we could simply use sizeof to get the size of our struct, and make our new records that size, and then write them using the DmWrite API, which has this prototype - Err DmWrite (void *recordP, UInt32 offset, const void *srcP, UInt32 bytes), where the void * is a pointer to our record, the offset indicates how far into the record to start writing, srcP points to the data, and the UInt32 indicates the number of bytes to write. An example would be as follows:

Char *s;

UInt16 offset = 0;

s = (Char *) MemHandleLock(DBEntry);

DmWrite(s, 0, br, sizeof(BugRecord));

MemHandleUnlock(DBEntry);

I'm sure that many of you spotted a problem. This isn't the full bug record, it does not contain a string. If you have to store data which does not involve strings, or the strings are of a fixed size, then life is easy. However, as I often say, space on the Palm is at a premium, and so if we have strings in our data, we must take steps to ensure that each record takes up the smallest amount of space possible. In order to do this, we need to undergo a process commonly referred to as 'packing' our struct into a record. In order to do this we create two struts, one which contains Char *'s, and the other which simply contains Char arrays with a length of 1. Here are the real structs from the Bug Squasher demo application.

typedef struct {

  DateType DateEntered;

  UInt8 nBugSeverity;

  UInt8 nBugType;

  char * szBugDesc;

} BugRecord;

typedef struct

  DateType DateEntered;

  UInt8 nBugSeverity;

  UInt8 nBugType;

  char szBugDesc[1];

} PackedBugRecord;

In this case we only have one string, but the example holds for as many strings as you would like. Because the only way to find the value of the nth string is to unpack all n strings, you should always place the most important strings at the top of the string list, and all non string information before that. Storing variable length records causes us to need another function, which we will use within a helpful function we write, called PackBug. The API function is called MemHandleResize, and it takes a record and a new length and like most Palm functions returns an Err which is 0 if there were no problems. Here is our PackBug function.

void PackBug(BugRecord *br, MemHandle DBEntry)

 UInt16 length = 0;

 Char *s;

 UInt16 offset = 0;

 length = (UInt16) (sizeof(BugRecord) + StrLen(br->szBugDesc) + 1);

 if (MemHandleResize(DBEntry, length) == errNone)

  s = (Char *) MemHandleLock(DBEntry);

  DmWrite(s, 0, br, sizeof(*br));

  DmStrCopy(s, OffsetOf(PackedBugRecord, szBugDesc), br->szBugDesc);

  MemHandleUnlock(DBEntry);

As you can see, we calculate the length of the record by the size of the struct and the length of the string, plus one for the null terminator. Obviously if you are storing more than one string then will need to store enough space to null terminate them all. Note also that the Palm API provides a function called OffsetOf, which allows us to find the offset within a struct of the string in question. The C standard library contains similar constructed called offsetof, and once again the Palm API provides an alternative which is easy to remember, and simply capitalises the words of the standard function.

Naturally having packed our bug, we also need to unpack it. This is simply a matter of assigning the right value to the variables within the struct. Obviously, if we had more than one string, we would need to use StrLength to figure out the right position for the start of each string in order to assign them. In The code looks like this.

void UnpackBug(BugRecord *bug, const PackedBugRecord *pBug)

 bug->DateEntered = pBug->DateEntered;

 bug->nBugSeverity = pBug->nBugSeverity;

 bug->nBugType = pBug->nBugType;

 bug->szBugDesc = pBug->szBugDesc;

Reading back our records

In this example I have used a GUI component which we have not yet discussed, namely a list. The list has been set to be ownerdrawn, and a callback has been set which will be passed the index of the item to draw. The details of this will be covered in a future article. Our strategy is to use the index passed into the overdrawn function to retrieve the appropriate record from our database and render it. This has the advantage of saving us from making a copy of our entire database, saving both space and processor time. There are two ways to search for a record, by index or by unique ID. The unique ID is not as exciting as it sounds, the search is still sequential and therefore has linear growth in complexity. It's far more common to search by index, but if you have the ID, the API is DmFindRecordByID, and it takes a database, a unique ID and a pointer which returns the index of the item. The DmQueryRecord function takes a database and a record number and returns a record handle or NULL to indicate failure. Here is the full code we use in our list callback to read a record.

Err err = 0;

MemHandle myRecord = DmQueryRecord(gDB, itemNum);

if (!myRecord)

    err = DmGetLastErr();

else

    PackedBugRecord *prec = (PackedBugRecord *) MemHandleLock(myRecord);

 BugRecord * rec = (BugRecord*) MemPtrNew(sizeof(BugRecord));

 UnpackBug(rec, prec);

After using WinDrawChars to render our data, we call MemHandleFree to free our records. We do not need to free the record data, because it was never copied out of the database.

Deleting Records

Deleting records is easy, just use DmRemoveRecord(gDB, nIndex), where gDB is your handle to a database, and nIndex is the record to delete.

Some other stuff

Records have a 64k limit, there is a way to overcome this, but I am not familiar with it. Each record also has a record attributes area, which is one byte in size and contains a deleted bit, a secret bit, a dirty bit, a busy bit and a 4 bit category. Records when they are deleted are not necesarily removed from the Palm. DmRemoveRecord deletes them entirely, DmDeleteRecord deletes the record but keeps the header and sets the bit, and DmArchiveRecord does not delete the record, but sets the bit. The reason for these differences is syncronisation, another future topic, which basically involves moving data between a Palm and a desktop application. Deleted records are moved to the end of the database and are not visible, even if they are still there. They are typically always removed at the next syncronisation.

Databases also have their own header, where data like the name, creator, and type is stored, along with some application specific data. This is the place to store data you want to keep only once for the entire database. Additionally, databases can be sorted, through the provided DmInsertionSort and DmQuickSort functions, both of which use a function pointer to allow the programmer to specify the sort order. Insertion while maintaining sort is provided by the DmFindSortPosition API, inserting into an existing record index causes all records below that one to be moved down accordingly.

Although I am unable to comment beyond what the Palm API can tell you about these functions, they seem worthwhile, we have a database at work with 40,000 records and without some sort of binary search, the search times are somewhat untenable.

Introduction

In the following article, I will demonstrate how to write an application for Palm OS, which makes use of network sockets provided by the system library NetLib. Using the methods described here, one can create an application functionally similar to Linux wget, downloading a file of choice from the internet using the HTTP protocol. I will assume that the reader is familiar with the basics of programming for the Palm OS platform.

Socket programming under Palm OS hardly differs from programming it under Unix-like systems. Therefore, everyone who has done this before under Unix should have no problems whatsoever applying their solution in the Palm OS case.

Initializing NetLib

In order to avail oneself of the benefits provided by a system library, one has to first determine its reference number. It is required in order to use any function belonging to that particular library. One should be careful here not to lose the reference number going from function to function, as that would make it impossible for the program to use any function belonging to that library. We obtain the reference number by calling SysLibFind(), providing a pointer to our variable (AppNetRefnum) as its parameter. Of course, the library we are looking for must be present in the system, and has to have already been loaded; while there should be no problems with this in the case of NetLib, it is wise to protect oneself against the errors returned by SysLibFind().

Having already obtained the reference number of our library, we can open and initialize it with the NetLibOpen() function; of course, we have to pass the reference number as one of its arguments. The function will try to bring up all network interfaces that have already been configured, so if there are none available, it will return an error. If NetLib has already been opened, the error returned by the function will be netErrAlreadyOpen – which can be safely ignored, as it merely informs us that opening the library was not necessary. This is worth remembering in order not to abort the whole operation due to this error.

One other thing one should do before beginning to play with sockets is testing the network connections. For this, one should use the NetLibConnectionRefresh() function, which checks and optionally opens (if we pass true as its second argument) all connections.

Once we are done with all the required operations on the socket, we should clean the system up by closing NetLib with the NetLibClose() function; this will protect the program from errors like netErrAlreadyOpen, later on.

Addressing

The addresses of a socket under Palm OS is stored in an appropriate structure, just like under Unix. Since in our case we use the addresses of Internet sockets, we can use the NetSocketAddrINType structure, in which we store three values. The address family determines the syntax of an address. We will be connecting to the Internet, so will be using IP addresses (we write netSocketAddrINET as this value). What remains are the number of the port and the IP address of the remote host. If the user provides a host name instead of an IP address, it will have to be resolved; fortunately the NetLibGetHostByName() can help us with this. In order to use it, we will need another structure that will store the host information – NetHostInfoBufType. The NetLibGetHostByName() function's arguments will then be the string containing the name of the host and a pointer to the output structure. After the function has been executed, NetHostInfoBufType contains an array called address, in which all IP addresses of the host in question are stored. The size of the address array depends on the netDNSMaxAddresses constant, so it can contain more than one IP address. We, on the other hand, are only interested in one, so we will just refer to the value stored under address[0]. Having thus obtained the host's IP address, we can write it into the aforementioned NetSocketAddrINType address structure.

We will then make use of this structure in order to attach our socket to a remote host.

Listing 1. Initialization of the NetLib library

Err err, errcode;
UInt8 allup;
UInt16 AppNetRefnum = 0;

// Look for a system library

err = SysLibFind("Net.lib", &AppNetRefnum);
if (err || !AppNetRefnum) return err;

// Open NetLib

NetLibOpen(AppNetRefnum, &errcode);
if (errcode && errcode != netErrAlreadyOpen)
return errcode;

// Refresh network connections

NetLibConnectionRefresh(AppNetRefnum,
true, &allup, &errcode);
if (errcode) {
NetLibClose(AppNetRefnum, true);
return errcode;
}
(...)
NetLibClose(AppNetRefnum, true);

Sockets

The time has come to actually open a network socket. In order to do this, we will need some information. To begin with, we need the domain – the value that we passed to the NetSocketAddrINType as the address family (netSocketAddrINET). Next, we will define the type of the socket, i.e., whether the connection is to use datagrams or streams; in our case, we have to specify netSocketTypeStream. We shall also have to choose an appropriate protocol, depending on the type of the socket; for a streaming socket, the right protocol will be TCP (netSocketProtoIPTCP). We are going to pass all this information as arguments to the NetLibSocketOpen() function, which in turn returns a socket descriptor that we are going to store in a NetSocketRef-type variable. We will be using this descriptor of an open socket in all the operations on this socket.

We have already got an open network socket and an address structure, so it is high time to establish a connection to the remote host (unless one uses datagram sockets, in which case, no connections have to be established, and we just provide the address data of an appropriate host in all send or receive operations on the socket). To connect a socket to the remote host, we use the NetLibSocketConnect() function, taking as parameters the socket descriptor and a pointer to the address structure. Now we can finally communicate with the remote host using the socket descriptor.

Having finished our communication, we close the network socket by calling the NetLibSocketClose() function.

Communicating with the remote host

After the connection has been established, the actual conversation with the server is just a question of sending queries and receiving replies. There are two functions we use in sending and receiving data – NetLibSend() and NetLibReceive(). The arguments they both take are the socket descriptor we have obtained earlier, a character string as a buffer of data to be sent or for data to be received, and a value defining the length of the buffer. Both functions return the number of bytes which have been transmitted – a very useful feature for verifying the accuracy of the communication. When a function returns zero, it implies that the server has closed the socket, meaning that all the data has been sent.

In the case of datagram sockets, we also have to provide a pointer to the address structure, along with its size.

At this point of our application, it is time to start considering the way, i.e., the protocol, of communication with the server. We have to know what to send to the server and what answers are to be expected. In the case of wget, the protocol used is HTTP, hence we too will be sending and receiving HTTP headers. The responses of an HTTP server consist of the header and the data. The header can tell us what the name and the size of the transmitted file is, giving us information about how many bytes we should write to a file and under what name. The headers can also contain appropriate error messages, which should be taken into account in the error-handling function of our application.

Listing 2. Addressing and communication with a remote host

Collapse

char host[] = "www.palmtop.pl";
char buffer[40]; // A buffer for sent/received data

int bytes = 1;
NetSocketRef sock;
NetSocketAddrINType addr;
NetHostInfoBufType hostinfo;

NetLibGetHostByName(
AppNetRefnum, host, &hostinfo, -1, &errcode);

if (errcode) return errcode;
addr.family = netSocketAddrINET;
addr.port = 80;
addr.addr = hostinfo.address[0];

// Open a network socket

sock = NetLibSocketOpen(
AppNetRefnum, netSocketAddrINET, netSocketTypeStream,
netSocketProtoIPTCP, -1, &errcode);

// Connect the socket to the specifi ed host and port

NetLibSocketConnect(AppNetRefnum, sock, &addr,
sizeof(addr), -1, &errcode);
if (errcode) {
 NetLibSocketClose (AppNetRefnum, sock, -1, &err);
 return errcode;
}

// Transmit the contents of the buffer through

// the socket to the host

NetLibSend(AppNetRefnum, sock, buffer,
StrLen(buffer), 0, 0, 0, -1, &errcode);

// Retrieve data from the socket to the buffer

while(bytes > 0)
bytes = NetLibReceive(AppNetRefnum, sock,
buffer, 40, 0, 0, 0, -1, &errcode);

// Close the network socket

NetLibSocketClose(AppNetRefnum, sock, -1, &errcode)

Communication with the user

While the data transmission is taking place, it would not hurt to keep the user informed about the progress of the data flow. For this purpose, the creators of Palm OS have created a special interface called Progress Manager.

Using Progress Manager, we can display and control the contents of a progress window. What is to be displayed in this window is controlled by a programmer-defined function called PrgCallbackFunc. A number of different progress states can be declared, e.g., Connecting, Retrieving, or Disconnecting. Just before connecting to the remote host, we open the progress window, calling the PrgStartDialog function, and giving it the title of the window and a pointer to the callback function; all further operations on the window's contents are to be performed with the PrgUpdateDialog function. This function makes it possible to switch between different progress states, provide the callback function with additional text output, or display an error message. Another thing worth mentioning here is the PrgUserCancel macro, which checks whether the user has not cancelled the operation while it was in progress.

1. Creat a file .r and go to the Settings to map the extension r with
PalmRez
2. This file .r has the header that looks like :

#define hsNavFlags   defaultStartStateValue = 0x00000000, \
     objectFocusStartState  = 0x00000001, \
     appFocusStartState     = 0x00000002

#define hsNavObjectFlags none             = 0x0000, \
     skip             = 0x0001, \
     forceInteraction = 0x0002, \
     bigButton        = 0x8000
type 'fnav' {
unsigned integer = 1;      /* resource version */
unsigned integer = $$Countof(ObjectArray);
unsigned integer = 20;      /* size of header */
unsigned integer = 8;      /* size of list elements */
unsigned longint hsNavFlags;    /* navigation flags */
unsigned integer;       /* ID of initial focus object */
unsigned integer = 0;      /* hint ID of jump to object */
unsigned integer = 0;      /* hint ID of bottom left object */
fill word;

array ObjectArray {
unsigned integer;      /* ID of object */
unsigned integer hsNavObjectFlags;  /* object flags */
unsigned integer;      /* ID of above object */
unsigned integer;      /* ID of below object */
};
};

resource 'fnav' ( MainForm )
{
objectFocusStartState,
MainFileTestButton,
{
MainFileTestButton, 0, 0, MainInputTestButton,

Changing the Application name in palm

noreply@blogger.com (sumesh) — Tue, 19 Feb 2008 04:42:00 +0000

There are several places you need to replace the word "starter" with "NewName":

1. It's not required, but you might want to rename starter.c as NewName.c. If you do that, then you will have to add NewName.c to your project. Highlight Source in the project window, then click menu items Project, then Add Files... to add NewName.c to your project. Then you should delete starter.c from the project by selecting it and pressing the delete key.

2. You should change all of the following settings for the starter project. Select Edit, then Starter Settings from the menu, then:
a) Under Target Name, change the name from "Starter" to "NewName".
b) Under 68K Target, change the file name from "Starter.tmp" to "NewName.tmp".
c) Under PalmRez Post Linker, change the output file from "Starter.prc" to "NewName.prc".
d) Also under PalmRezPostLinker, change the Mac Resource Files from "Starter.tmp" to "newName.tmp". This file name must be the same as thefile name in step b.

e) click the Save button to save the project settings.

3. Finally, you need to change the name the launcher uses for your app. To do this, open starter.rsrc from the project window. Change the Application Icon Name from "Starter" to "NewName". (You might also want to change the name of the resource file. If you are using windows, that is slightly painful because the file is stored in two parts: \Rsc\Starter.rsrc and \Rsc\Resource.frk\starter.rsrc. So you have to rename both files, then add NewName.rsrc to your project.

4. One other thing you might want to rename is the header file generated by constructor, StarterRsc.h. To do that, open Constructor, rename "StarterRsc.h" to "NewName.h", and save the resource. Then you have to open NewName.c (formerly Starter.c) and change the line '#include "StarterRsc.h"' to '#include "NewName.h"'.

5. And, You probably should rename Starter.mcp to NewName.mcp The easiest way to do that is with Windows explorer. Alternatively, you could select File, then Save a Copy As... from the CodeWarrior menu to save the project file with the new name. But then you'd have two copies and would still have to delete starter.mcp.

And to change the default apps bitmap ( Icon )

Open your resource file with Constructor, then highlight Icons, and press ctrl-K to create a new icon. Give it a name. Make sure its ID is 1000. Then double-click it to open the icon editor. Draw your picture, close the editor, save the resource file, and compile your project. You can also make color icons using Icon Families instead of Icons.

Top Ten Languages

noreply@blogger.com (sumesh) — Thu, 17 Jan 2008 10:49:00 +0000

10. French -- Number of speakers: 129 million
Often called the most romantic language in the world, French is spoken in
tons of countries, including Belgium, Canada, Rwanda, Cameroon, and Haiti.
Oh, and France too.. We're actually very lucky that French is so popular,
because without it, we might have been stuck with Dutch Toast, Dutch
Fries, and Dutch kissing (ew!).
To say "hello" in French, say "Bonjour" (bone-JOOR).

9. Malay—Indonesian Number of speakers: 159 million
Malay-Indonesian is spoken - surprise - in Malaysia and Indonesia.
Actually, we kinda fudged the numbers on this one because there are many
dialects of Malay, the most popular of which is Indonesian. But they're
all pretty much based on the same root language, which makes it the ninth
most-spoken in the world.Indonesia is a fascinating place; a nation made
up of over 13,000 islands it is the sixth most populated country in the
world. Malaysia borders on two of the larger parts of Indonesia (including
the island of Borneo), and is mostly known for its capital city of Kuala
Lumpur.
To say "hello" in Indonesian, say "Selamat pagi" (se-LA-maht PA-gee).

8. Portuguese -- Number of speakers: 191 million
Think of Portuguese as the little language that could. In the 12th
Century, Portugal won its independence from Spain and expanded all over
the world with the help of its famous explorers like Vasco da Gama and
Prince Henry the Navigator. (Good thing Henry became a navigator . . .
could you imagine if a guy named "Prince Henry the Navigator" became a
florist?) Because Portugal got in so early on the exploring game, the
language established itself all over the world, especially in Brazil
(where it's the national language), Macau, Angola, Venezuela, and
Mozambique.
To say "hello" in Portuguese, say "Bom dia" (bohn DEE-ah).

7. Bengali -- Number of speakers: 211 million
In Bangladesh, a country of 120+ million people, just about everybody
speaks Bengali. And because Bangladesh is virtually surrounded by India
(where the population is growing so fast, just breathing the air can get
you pregnant), the number of Bengali speakers in the world is much higher
than most people would expect.
To say "hello" in Bengali, say "Ei Je" (EYE-jay).

6. Arabic -- Number of speakers: 246 million
Arabic, one of the world's oldest languages, is spoken in the Middle East,
with speakers found in countries such as Saudi Arabia, Kuwait, Iraq,
Syria, Jordan, Lebanon, and Egypt. Furthermore, because Arabic is the
language of the Koran, millions of Moslems in other countries speak Arabic
as well. So many people have a working knowledge of Arabic, in fact, that
in 1974 it was made the sixth official language of the United Nations.
To say "hello" in Arabic, say "Al salaam a'alaykum" (Ahl sah-LAHM ah
ah-LAY-koom) .

5. Russian -- Number of speakers: 277 million
Mikhail Gorbachev, Boris Yeltsin, and Yakov Smirnoff are among the
millions of Russian speakers out there. Sure, we used to think of them as
our Commie enemies. Now we think of them as our Commie friends. One of the
six languages in the UN, Russian is spoken not only in the Mother Country,
but also in Belarus, Kazakhstan, and the U.S. (to name just a few places).
To say "hello" in Russian, say "Zdravstvuite" (ZDRAST-vet- yah).

4. Spanish -- Number of speakers: 392 million
Aside from all of those kids who take it in high school, Spanish is spoken
in just about every South American and Central American country, not to
mention Spain, Cuba, and the U.S. There is a particular interest in
Spanish in the U.S., as many English words are borrowed from the language,
including: tornado, bonanza, patio, quesadilla, enchilada, and taco grande
supreme.
To say "hello" in Spanish, say "Hola" (OH-la).

3. Hindustani -- Number of speakers: 497 million
Hindustani is the primary language of India's crowded population, and it
encompasses a huge number of dialects (of which the most commonly spoken
is Hindi). While many predict that the population of India will soon
surpass that of China, the prominence of English in India prevents
Hindustani from surpassing the most popular language in the world. If
you're interested in learning a little Hindi, there's a very easy way:
rent an Indian movie. The film industry in India is the most prolific in
the world, making thousands of action/romance/ musicals every year.
To say "hello" in Hindustani, say "Namaste" (Nah-MAH-stay) .

2. English -- Number of speakers: 508 million
While English doesn't have the most speakers, it is the official language
of more countries than any other language. Its speakers hail from all
around the world, including the U.S., Australia, England, Zimbabwe, the
Caribbean, Hong Kong, South Africa, and Canada. We'd tell you more about
English, but you probably feel pretty comfortable with the language
already. Let's just move on to the most popular language in the world.
To say "hello" in English, say "What's up, freak?" (watz-UP-freek) .

1. Mandarin -- Number of speakers: 1 billion+

Surprise, surprise, the most widely spoken language on the planet is based
in the most populated country on the planet, China. Beating second-place
English by a 2 to 1 ratio, but don't let that lull you into thinking that
Mandarin is easy to learn. Speaking Mandarin can be really tough, because
each word can be pronounced in four ways (or "tones"), and a beginner will
invariably have trouble distinguishing one tone from another. But if over
a billion people could do it, so could you. Try saying hello!
To say "hello" in Mandarin, say "Ni hao" (Nee HaOW). ("Hao" is pronounced
as one syllable, but the tone requires that you let your voice drop
midway, and then raise it again at the end.)
