Platform Invoke Tutorial

2010-09-19T03:22:00.000-07:00

Q. what achually it is?
Platform Invocation Services (PInvoke) allows managed code (for example code written in C sharp)to call unmanaged functions that are implemented in a DLL( for example th ecode you write in CUDA and create a dll of it).

for this you are required to tell your C Sharp Application that your application CONTAIN A CALL TO DLL.
1. USE NAMESPACE:: System.Runtime.InteropServices.
2. you must provide the C# compiler with a declaration of the unmanaged function.
for this include fallowing statiment just After the constructor of your class.

[DllImport("STRING PATH OF DLL ")]
public static extern RETURN TYPE FUNTION NAME ( @ PARAMS);

Declare the method with the static and extern C# keywords.
1 why static :: to associate the dll method with the calling class.
2. why extern:: to tell C sharp compiler that the method is from outside( not belongs to C sharp class).
3.RETURN TYPE :: It is the return type of the funtion which is being declared in C dll .
here the important thing is thats C# does not support various return type as C ( like pointer )
hence we are required to convert these return type into C# compitable return type.
4. Funtion name:: may or may not be same as DLL funtion name.
5.Formal params to function:: the are also not supported and required to get change.

creating dll of C using visual studio for plateform invoke form C sharp.

If you approach to write CUDA program or some other application. For which you are required to build dll of C program such that you could create the GUI for that application in language like C sharp.

For this structure of your C program is supposed to be as::

extern "C"             //
       {
           __declspec(dllexport) returntype funtionname (...)
                   {
                   ....................................the boby of your funtion................

                   }
         }
1.extern "C":::extern "C" is meant to be recognized by a C++ compiler and to notify the compiler that the noted function is (or to be) compiled in C style..since you are working in VC++ hence its good to write.

2.__declspec(dllexport):: when we pass a function to a dll it is always necessary to tell which function is to be include and which is not required.
These attributes explicitly define the DLL's interface to its client, which can be the executable file or another DLL. Declaring functions as dllexport eliminates the need for a module-definition (.DEF) file, at least with respect to the specification of exported functions.

STEP 2: making DLL:
visual studio> project > project property> Configuration property> configuration type=Dynamic Library (.dll)

ACTIVE-X

2010-06-09T12:59:00.000-07:00

ActiveX is a framework for defining reusable software components in a programming language independent way. Software applications can then be composed from one or more of these components in order to provide their functionality.^[1]

It was introduced in 1996 by Microsoft as a development of its Component Object Model (COM) and Object Linking and Embedding (OLE) technologies and is commonly used in itsWindows operating system, although the technology itself is not tied to it.

Many Microsoft Windows applications — including many of those from Microsoft itself, such as Internet Explorer, Microsoft Office, Microsoft Visual Studio, and Windows Media Player — use ActiveX controls to build their feature-set and also encapsulate their own functionality as ActiveX controls which can then be embedded into other applications. Internet Explorer also allows embedding ActiveX controls onto web pages.

ActiveX controls — small program building blocks — can serve to create distributed applications that work over the Internet through web browsers. Examples include customized applications for gathering data, viewing certain kinds of files, and displaying animation.

One can compare ActiveX controls in some sense to Java applets: programmers designed both of these mechanisms so that web browsers could download and execute them. However, they also differ:

Java applets can run on nearly any platform, while ActiveX components officially operate only with Microsoft's Internet Explorer web browserand the Microsoft Windows operating system.^[2]
Programmers can grant to ActiveX controls a much higher level of control over Windows than Java applets ever achieve, making them more powerful but also potentially more dangerous.

Malware, such as computer viruses and spyware, can be accidentally installed from malicious websites using ActiveX controls (drive-by downloads).

Programmers can write ActiveX controls in any language that supports COM component development, including the following languages/environments:

C++ either directly or with the help of libraries such as ATL or MFC^[3]
C#, and any other language built on the .NET Framework^[4]
Borland Delphi
Visual Basic

Common examples of ActiveX controls include command buttons, list boxes, dialog boxes, and the Internet Explorer browser.

WINDOWS CE

2010-06-09T12:55:00.000-07:00

Windows CE (also known officially as Windows Embedded Compact or Windows Embedded CE post version 6.0 ^[2]^[3], and sometimes abbreviated WinCE) is an operating system developed by Microsoft for minimalistic computers and embedded systems. Windows CE is a distinct operating system^{[citation needed]} and kernel, rather than a trimmed-down version of desktop Windows. Microsoft licenses Windows CE to OEMs and device makers. The OEMs and device makers can modify and create their own user interfaces and experiences, while Windows CE provides the technical foundation to do so. It is not to be confused with Windows XP Embedded which is NT-based. Windows CE is supported on Intel x86 and compatibles, MIPS, ARM, and Hitachi SuperH processors.

Windows CE is optimized for devices that have minimal storage—a Windows CE kernel may run in under a megabyte of memory. Devices are often configured without disk storage, and may be configured as a “closed” system that does not allow for end-user extension (for instance, it can be burned into ROM). Windows CE conforms to the definition of a real-time operating system, with a deterministic interrupt latency. From version 3 and onward, the system supports 256 priority levels^[4] and uses priority inheritance for dealing with priority inversion. The fundamental unit of execution is the thread. This helps to simplify the interface and improve execution time.

Microsoft has stated that the ‘CE’ is not an intentional initialism, but many people believe CE stands for ‘Consumer Electronics’ or ‘Compact Edition’. Microsoft says it implies a number of Windows CE design precepts, including “Compact, Connectable, Compatible, Companion, and Efficient.”^[5] The first version, known during development under the code name “Pegasus”, featured a Windows-like GUI and a number of Microsoft's popular applications, all trimmed down for smaller storage, memory, and speed of the palmtops of the day.

Since then, Windows CE has evolved into a component-based, embedded, real-time operating system. It is no longer targeted solely at hand-held computers^[6]. Many platforms have been based on the core Windows CE operating system, including Microsoft's AutoPC, Pocket PC 2000, Pocket PC 2002, Windows Mobile 2003, Windows Mobile 2003 SE, Windows Mobile 5.0, Windows Mobile 6, Smartphone 2002, Smartphone 2003, Portable Media Center and many industrial devices and embedded systems. Windows CE even powered select games for the Dreamcast, was the operating system of the Gizmondo handheld, and can partially run on modified Xbox game consoles.

A distinctive feature of Windows CE compared to other Microsoft operating systems is that large parts of it are offered in source code form. First, source code was offered to several vendors, so they could adjust it to their hardware. Then products like Platform Builder (an integrated environment for Windows CE OS image creation and integration, or customized operating system designs based on CE) offered several components in source code form to the general public. However, a number of core components that do not need adaptation to specific hardware environments (other than the CPU family) are still distributed in binary only form.

Relationship to Windows Mobile, Pocket PC, and SmartPhone

Often Windows CE, Windows Mobile, and Pocket PC are used interchangeably - in part due to their common origin. This practice is not entirely accurate. Windows CE is a modular/componentized operating system that serves as the foundation of several classes of devices. Some of these modules provide subsets of other components' features (e.g. varying levels of windowing support; DCOM vs COM), others which are separate (Bitmap or TrueType font support), and others which add additional features to another component. One can buy a kit (the Platform Builder) which contains all these components and the tools with which to develop a custom platform. Applications such as Excel Mobile/Pocket Excel are not part of this kit. The older Handheld PC version of Pocket Word and several other older applications are included as samples, however.

Windows Mobile is best described as a subset of platforms based on a Windows CE underpinning. Currently, Pocket PC (now called Windows Mobile Classic), SmartPhone (Windows Mobile Standard), and PocketPC Phone Edition (Windows Mobile Professional) are the three main platforms under the Windows Mobile umbrella. Each platform utilizes different components of Windows CE, as well as supplemental features and applications suited for their respective devices.

Pocket PC and Windows Mobile is a Microsoft-defined custom platform for general PDA use, and consists of a Microsoft-defined set of minimum profiles (Professional Edition, Premium Edition) of software and hardware that is supported. The rules for manufacturing a Pocket PC device are stricter than those for producing a custom Windows CE-based platform. The defining characteristics of the Pocket PC are the digitizer as the primary human interface device and its extremely portable size.

The SmartPhone platform is a feature rich OS and interface for cellular phone handsets. SmartPhone offers productivity features to business users, such as email, as well as multimedia capabilities for consumers. The SmartPhone interface relies heavily on joystick navigation and PhonePad input. Devices running SmartPhone do not include a touchscreen interface. SmartPhone devices generally resemble other cellular handset form factors, whereas most Phone Edition devices use a PDA form factor with a larger display.

THE DARK SIDE OF NTFS

2010-06-09T12:33:00.000-07:00

What is NTFS?
It is the abbreviation of New Technology File System - Windows NT's preferred file system.
What is an alternate data stream (ADS)?
In NTFS, a file consits of different data streams. One stream holds the security information (access
rights and such things), another one holds the "real data" you expect to be in a file. There may be another
stream with link information instead of the real data stream, if the file actually is a link. And there may
be alternate data streams, holding data the same way the standard data stream does.
What is wrong with alternate data streams?
I could say: Nothing, they work as expected and as documented (yes, Microsoft did document this
feature).
But stop - there is something wrong: They are totally hidden. You can have a file with 1 byte in the
official main data stream and some hundred MB in one or more alternate data streams. What do you
expect the dir command, file manager or explorer to show as the size of this file? It is 1 byte!
That means a user can hide quite a lot of data in alternate data
streams and nobody will know?
So it is.
But a user does need certain special priviledges to use
alternate data streams?
No. Even guest can create such streams in every file where he has write access for.

How does somebody create an ADS?
You can do it on the command prompt, like notepad visible.txt:hidden.txt. This will
create an hidden stream hidden.txt in the file visible.txt. It doesn't matter if the file exists
or not.
How does somebody copy data into an ADS?
type atextfile > visible.txt:hidden2.txt.
This will create another hidden stream hidden2.txt in the file visible.txt.
How does somebody copy text data from an ADS into a
"normal" file?
more < visible.txt:hidden2.txt > newfile.txt.
This will create a file newfile.txt from the hidden stream hidden2.txt in the file visible.
txt.
How does somebody copy binary data from an ADS into a
"normal" file?
cat visible.txt:hidden.exe > hack.exe.
This will create a file hack.exe from the hidden stream hidden.exe in the file visible.txt.
(Cat is a tool from the Ressource Kit.)
How does somebody delete an ADS?
Let us assume you know there is a file important.exe with an ADS attached to it. The file is very
important and the ADS very dangerous. You need to hold the main stream and delete the ADS. Let us
assume there is no FAT drive on your network, otherwise you could move the file to this drive and than
move it back again. All you need to do is:
ren important.exe temp.exe
cat temp.exe > important.exe
del temp.exe
The method above does not work when the ADS is attached to a directory. If you need to remove,
for instance c:\Windows:harmful.exe without reinstalling Windows, you could use this trick. (If you use
NT 5.x, you need a copy of Notepad.exe from NT 4!)

1. Open the ADS with Notepad:
C:\NT4Tools\Notepad.exe c:\Windows:harmful.exe
2. Delete the entire content of the ADS
3. Close notepad. It will ask whether you want to save your changes
4. Answer YES
5. Notpad will tell you that the file is empty and that it will delete it
Now you are done, the ADS is gone.
Can somebody add an ADS to a directory entry instead of a
file?
Yes, it works the same way.
What possibilities does Microsoft provide to check if there are
alternate data streams on my NTFS disks?
Do you expect they care?
But if the sum of available and used storage on a hard disk is
much less than it's size, I want to know a way to check if there
are alternate data streams on my NTFS disks!
You can move all files onto a FAT drive and back to the NTFS drive. This way all alternate data streams
will be deleted, because FAT does not know how to save this kind of data.

REGISTRY THE INTRO

2010-03-12T03:50:00.000-08:00

DEFINITION: The Windows 9x/NT/2000/ME/XP Registry is a complex, unified, system wide, continually referenced during operation database, used for centrally storing, locating, editing and administering system, hardware, software and user configuration information, following a hierarchical structure.
It was introduced to replace the text/ASCII based MS -DOS configuration (.BAT, .SYS) and MS Windows initialization (.INI) files.

Structure of Registry in windows 9X is Different from that of Windows NT,2000 and XP.

Windows 95/98/ME :In these operating systems Registry is stored in these 5 files, with the Hidden, Read-only attributes for write-protection purposes, usually located in the %WinDir% folder (default is C:\Windows)
."

SYSTEM.DAT = stores persistent hardware and software settings related to the system it resides on, contained in the (HKEY_CLASSES_ROOT = Windows 95 and 98 only) and HKEY_LOCAL_MACHINE Hive keys.
USER.DAT = stores user specific and software settings contained in the HKEY_CURRENT_USER Hive key. If more than one user, then multiple user profiles enable each user to have their own separate USER.DAT file, located in %WinDir%\Profiles\%UserName%. When a user logs on, Windows OS (down)loads both USER.DAT files: the one from the local machine %WinDir% (global user settings), and the most recent one from the local machine %WinDir%\Profiles\%UserName%, or from the central (host) server if user profiles reside on a network (local user settings).
CLASSES.DAT = stores persistent data contained in the HKEY_CLASSES_ROOT Hive key, found only on Windows ME.
SYSTEM.DA0 and USER.DA0 = automatically created backups of SYSTEM.DAT and USER.DAT from the last successful Windows GUI startup, and found only on Windows 95

Windows NT/2000/XP :Registration Database is contained in these 5 files located in the %SystemRoot%\System32\Config folder (default is C:\Winnt\System32\Config for Windows NT/2000 or C:\Windows\System32\Config for Windows XP):

DEFAULT = stores the HKEY_USERS\.Default key.
SAM = stores the HKEY_LOCAL_MACHINE\Sam key.
SECURITY = stores the HKEY_LOCAL_MACHINE\Security key.
SOFTWARE = stores the HKEY_LOCAL_MACHINE\Software key.
SYSTEM = stores the HKEY_LOCAL_MACHINE\System key and the HKEY_CURRENT_CONFIG Hive key,

these files located in the %SystemRoot%\Profiles\%UserName% folder:
NTUSER.DAT and USRCLASS.DAT (Windows XP only) = store the HKEY_CURRENT_USER Hive key,

Editing Registry

Always make sure that you know what you are doing when changing the registry or else just one little mistake can crash the whole system. That's why it's always good to back it up!

To view the registry (or to back it up), you need to use the Registry Editor tool. There are two versions of Registry Editor:

:To modify the Registry, you need to use a Registry Editor:

Regedit.exe (Windows 95/98/ME/NT/2000/XP) = located in %WinBootDir% (%SystemRoot%) has the most menu items and more choices for the menu items. You can search for keys and subkeys in the registry.
Regedt32.exe (Windows NT/2000/XP) = located in %SystemRoot%\System32,enables you to search for strings, values, keys, and subkeys. This feature is useful if you want to find specific data.

Registry Structure

For ease of use, the Registry is divided into five separate structures that represent the Registry database in its entirety. These five groups are known as Keys, and are discussed below:

HKEY_CURRENT_USER
This registry key contains the configuration information for the user that is currently logged in. The users folders, screen colors, and control panel settings are stored here. This information is known as a User Profile.

HKEY_USERS
In windowsNT 3.5x, user profiles were stored locally (by default) in the systemroot\system32\config directory. In NT4.0, they are stored in the systemroot\profiles directory. User-Specific information is kept there, as well as common, system wide user information.

HKEY_LOCAL_MACHINE
This key contains configuration information particular to the computer. This information is stored in the systemroot\system32\config directory as persistent operating system files, with the exception of the volatile hardware key.

HKEY_CLASSES_ROOT
The information stored here is used to open the correct application when a file is opened by using Explorer and for Object Linking and Embedding. It is actually a window that reflects information from the HKEY_LOCAL_MACHINE\Software subkey.

HKEY_CURRENT_CONFIG
The information contained in this key is to configure settings such as the software and device drivers to load or the display resolution to use. This key has a software and system subkeys, which keep track of configuration information.

"Add\delete programs to run every time Windows starts

You can start or stop programs from executing at boot up by adding or deleting them to/from the run Keys in the Registry. Windows loads programs to start in the following order; Program listed in the Local Machine hive, then the Current User hive, then theWin.ini Run= and Load = lines. then finally programs in your Start Up folder.

To add or remove programs in the Registry
1.Open RegEdit
2.Go to the desired Key
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows \CurrentVersion \Run
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows \CurrentVersion \RunServices
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows \CurrentVersion \Run
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows \CurrentVersion \RunServices
3. Add a new String Value and name it anything you like
4. For the value data, enter the path and executable for the program you want to run.

By adding the value to the HKEY_CURRENT_USER hive instead allows the program to start only when that user is logged on.

If you add the value to the RunOnce key the program will run once and be removed from the key by Windows."

2.Go to HKEY_CLASSES_ROOT\Directory\Shell
3.Right-click on Shell and select New Key
4.Type in the name of the key and press the Enter key
5.In the Default name that shows in the right hand panel, you can add a title with a '&' character in front of the letter for a shortcut
6.Right-click on the key you just created and create another key under it called command
7.For the value of this command, enter the full path and program you want to execute
8.Now when you right click on the Start Button, your new program will be there.
9.For example, if you want Word to be added, you would add that as the first key, the default in the right panel would be &Word so when you right click on the Start Button, the W would be the Hot Key on your keyboard. The value of the key would be C:\Program Files\Office\Winword\Winword.exe"

"Changing the MaxMTU for faster Downloads

There are four Internet settings that can be configured, you can get greater throughput (faster Internet downloads) by modifying a few settings.
They are the MaxMTU, MaxMSS and DefaultRcvWindow, and DefaultTTL

1.Open RegEdit
2.Go to
HKEY_LOCAL_MACHINE\System\CurrentControlset\ Services\ Class\ net\ 000x
(where x is your particular network adapter binding.)
3.Right click on the right panel
4.Select New\String Value and create the value name IPMTU
5.Double click on it and enter then the number you want. The usual change is to 576
6.Similarly, you can add IPMSS and give it a value of 536

(Windows 9X)You can set DefaultRcvWindow, and DefaultTTL by adding these string values to HKEY_LOCAL_MACHINE\ System\ CurrentControlset\ Services\ VXD\ MSTCP
Set the DefaultRcvWindow to'5840'and the DefaultTTL to '128'

Note: These settings will slow down your network access speed slightly, but you will probably not even see the difference if you are using a network card. If you are using Direct Cable you should see a sight difference."

DELETING REGISTRY KEYS

2010-03-12T03:27:00.000-08:00

There are two ways to delete a key from the Registry from the Command line. At the Windows Command line:

RegEdit /l location of System.dat /R location of User.dat /D Registry key to delete
You cannot be in Windows at the time you use this switch.

Or you can create a reg file as such:
REGEDIT4

[-HKEY_LOCAL_MACHINE\the key you want to delete]
Note the negative sign just behind the[
Then at the Command line type:
1. RegEdit C:\Windows\(name of the regfile)."
