Convert all words first letter to upper case (RegEx & Notepad++)

2017-10-02T00:24:00.001-07:00

From time to time we need to replace the first letter of many words to the upper case.

String: "word1" "word2" "word3 and/or word4"

Find part: "\b(\w)(\w+)"

Replace part: "\u$1\E$2"

Result: "Word1" "Word2" "Word3 And/Or Word4"

If we want to exclude any word, e.g and, or, so we can make this so:

String: "word1" "word2" "word3 and/or word4"

Find part: "\b(?!and|or)(\w)(\w+)"

Replace part: "\u$1\E$2"

Result: "Word1" "Word2" "Word3 and/or Word4"

JavaScript >>> save Objects/Arrays in localStorage/sessionStorage

2016-02-24T06:21:00.003-08:00

To save objects or arrays in localStorage/sessionStorage you should JSON.stringify the object or array:

var testObject = { 'one': 1, 'two': 2, 'three': 3 };window.localStorage.setItem("testObject", JSON.stringify(testObject));

To read a object/array from localStorage/sessionStorage you should JSON.parse the result of it:

var result = JSON.parse(window.localStorage.getItem("testObject");

ColdFusion/Kendo UI/Javascript >>> Kendo UI Grid ServerPaging

2016-02-17T05:37:00.002-08:00

Here is a simple example of serverPaging with Kendo UI and the related RESTful Service in ConldFusion:

Kendo UI/Javascript part:

$scope.source = new kendo.data.DataSource({
transport: {
read: function(options) {
$.ajax({
url: "http://localhost:8500/rest/Services/kendoservice",
// options.data contains data such take, skip, page and pageSize! This is needed for serverPaging!
data: options.data,
// "jsonp" is required for cross-domain requests; use "json" for same-domain requests
dataType: "json",
// function for success request
success: function(result) {
...
$scope.$apply();
}
// function for the case, if everything go wrong
, error: function(result) {
// notify the data source that the request failed
options.error(result);

$scope.$apply();
}
, chache: true
});
}
}
,pageSize: 15
, serverPaging: true
// definition of the response data:
// data >>> load data
// total >>> length of load data
, schema: {
data: "data",
total: "total"
}
});

In this request we give the paging data, such as take, skip, page, pageSize, as query parameters:

data: options.data

For functional server paging you must set next flags:

...
pageSize: 15,
serverPaging: true,
schema: {
data: "data",
total: "total"
}

On SCHEMA you can see, which keys your response must contain and other things. In this case your response JSON-object should contains two keys, 'data' and 'total'.

'data' contains array of JSON-objects.
'total' contains value of total row number!

Response example:

{"total":9557,"data":[{"index":1,"custCompany":"dfh"},{"index":5,"custCompany":"setes"}]}

ColdFusion RESTfull Service part:

component rest="true" restpath="/kendoservice" produces="application/json"
{
remote any function getKendoService(string take restArgSource="query", string skip restArgSource="query", string page restArgSource="query", string pageSize restArgSource="query") httpMethod="get"
{
var quotationElementList = new QuotationBaseDAO().listData();

var start = javaCast("int", skip) + 1;
var finish = start + javaCast("int", take);
var quotationList = ArrayNew(1);

for(i = start; i LT finish; i++){
if(i GTE ArrayLen(quotationElementList)){
break;
}

ArrayAppend(quotationList, quotationElementList[i]);
}
var response = serializeJSON({"data": quotationList, "total":ArrayLen(quotationElementList)});

// remove first two // chars, if existed!
if(response.startsWith("//") && Len(response) > 2){
response = response.substring(2);
}

return response;
}

}

In this webservice we use only skip and take parameter to calculate next entry point in the list and create new list with page data.

Coldfusion >>> REST Webservices

2016-02-17T01:27:00.001-08:00

The very good introduction and examples you can find here:

Below you can see a few examples of RESTful Webservices with different kinds of params (path, query) and only GET:

without params

component rest="true" restpath="/users" produces="application/json"
{
remote any function getUsers( ) httpmethod="GET"
{
var response = "";
...

return response;
}
}

Call: http://localhost:8080/rest/users

with param as part of the path in the call

component rest="true" restpath="/user" produces="application/json"
{
remote any function getUser(numeric userid restargsource="Path") httpmethod="GET" restpath="{userid}"
{
var response = "";
...

return response;
}
}

Call: http://localhost:8080/rest/user/12345

with param as query in the call
Notice: to use this case change restargsource to 'query' and you remove the restpath

component rest="true" restpath="/user" produces="application/json"
{
remote any function getUser(numeric userid restargsource="Query") httpmethod="GET"
{
var response = "";
...

return response;
}
}

Call: http://localhost:8080/rest/user?userid=12345

with more than one params:

CASE >>> params as part of the path:

component rest="true" restpath="/user" produces="application/json"
{
remote any function getUser(numeric userid restargsource="Path", numeric clientid restargsource="Path") httpmethod="GET" restpath="{userid, clientid}"
{
var response = "";
...

return response;
}
}

Call: http://localhost:8080/rest/user/12345/1

CASE >>> params in the query:

component rest="true" restpath="/user" produces="application/json"
{
remote any function getUser(numeric userid restargsource="Query", numeric clientid restargsource="Query") httpmethod="GET"
{
var response = "";
...

return response;
}
}

Call: http://localhost:8080/rest/user?userid=12345&clientid=1

CASE >>> mixed:

component rest="true" restpath="/user" produces="application/json"
{
remote any function getUser(numeric userid restargsource="Path", numeric clientid restargsource="Query") httpmethod="GET" restpath="{userid}"
{
var response = "";
...

return response;
}
}

Call: http://localhost:8080/rest/user/12345?clientid=1

Kendo UI >>> add row number to grid

2015-12-15T05:34:00.001-08:00

To add row number to kendo-grid you must make next steps:

1) create a counter variable:

var record = 0;

2) add the new column to your code:

columns: [
{
title: "#",
template: "#= ++record #",
width: 50
},{
field: "qtnumber",
title: "Nummer"
},{
field: "name",
title: "Name"
}
.....
]

3) write binding:

columns: [
...
],
dataBinding: function() {
record = (this.dataSource.page() -1) * this.dataSource.pageSize();
}

Note: the record variable should be defined as global. Also if you write this code in the global scope, so you can use record, in other case you should use window.record:

instead of

template: "#= ++record #"

write

template: "#= ++window.record #"

instead of

record = (this.dataSource.page() -1) * this.dataSource.pageSize()

write

window.record = (this.dataSource.page() -1) * this.dataSource.pageSize()

JavaScript >>> How to have a textarea to keep scrolled to the bottom

2015-09-02T05:11:00.000-07:00

To have auto-scroll function for <textarea> you can use next function for Javascript:

function scrollTextAreaToBottom(id){

if(id){

var element = document.getElementById(id);

element.scrollTop = element.scrollHeight;

}

Or for jQuery:

function scrollTextAreaToBottom(id){

if(id){

$(id).scrollTop($(id)[0].scrollHeight);

}

Anroid >>> create simple custom progress-bar (circle)

2015-08-17T14:29:00.001-07:00

Per default, you can not modify progress bar in Android, also for example change color. Therefore, we must create our own progress bar.

Step 1: create your circle progress bar image, e.g. with Gimp. And save it as wheel.png

Step 2: create mywheel.xml

<rotate xmlns:android="http://schemas.android.com/apk/res/android"    android:drawable="@drawable/wheel"    android:pivotX="50%"    android:pivotY="50%"    android:layout_height="wrap_content"    android:layout_width="wrap_content"    android:fromDegrees="0"
    />

With "duration" we can control the speed of the animation

Step 3: add ProgressBar to the View.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"    android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"    android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivityFragment"    android:background="@android:color/holo_blue_light"    >
    
    <ProgressBar        style="?android:attr/progressBarStyleLarge"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:id="@+id/progressBar"        android:layout_centerVertical="true"        android:layout_centerHorizontal="true"
        android:indeterminateDuration="1080"
        android:indeterminateDrawable="@drawable/mywheel"
        />

</RelativeLayout>

Android >>> change button background to transparent and highlight it on touch

2015-08-09T13:03:00.002-07:00

Problem:

we must set button background to transparent and highlight it on touch.

Solution:

to resolve this proble use only

android:background="?android:selectableItemBackground"

in your xml.

Example:

<Button    android:id="@+id/btnWriteConfig"    android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:text="Hold and tap the box to write configuration"    android:minHeight="40dp"    android:background="?android:selectableItemBackground"
    android:textColor="@android:color/white"    android:textStyle="bold"    android:layout_centerInParent="true"    />

Jasper Reports >>> Create custom scriptlet and use it in Jasper Soft

2015-07-30T07:41:00.002-07:00

A scriptlet is a Java class used to execute specific operations during report generation. Here is the simplest scriptlet implementation:

Additional we can use our (custom function) which we can use in Expresion Editor for example in Jasper Studio.

How to create a Scriptlet?

Step 1:
Create new Java Project in Eclipse and new class for example MyScriptlet.

Step 2:
Add jasperreports-X.X.X.jar to classpath. You find this lib for example in

C:\Program Files\Jaspersoft\Jaspersoft Studio-5.5.1.final\configuration\org.eclipse.osgi\bundles\413\1\.cp\lib\

Step 3:
Create new function

Step 4:
Create JAR for this: Right click on your project >>> click on 'Export' >>> choise 'Java' -> 'JAR file' >>> click on 'Next' >>> fill 'Select the export destination' >>> click on 'Finish'

How to use scriptlet in your project?

Step 1:
Create new Jasper Report Project: 'File' -> 'New' -> 'Project' >>> Select 'JasperReports Project' >>> click on 'Next' >>> set project name >>> click on 'Finish'

Step 2:
Create new Jasper Report: right click on your project >>> 'New' -> 'Jasper Report' >>> select 'Report Template' >>> click on 'Next' >>> set 'File name', also the report name >>> click on 'Next' >>> select your 'Data Adapter' or create one new >>> click on 'Finish'

Step 3:
Add MyScriptlet.jar, that we created above to classpath.

Step 4:
Now we have to set scriptlet in the report properties. See next image:

Step 5:
Create 'Text Field' (1) and double click on it to enter 'Expresion Editor' (2). Now select 'Parameters' (3) >>> 'REPORT_SCRIPTLET' (4). And on right side you can see your scriptlet function (5).

Note: In some case you can´t see the scriptlet functions. To resolve it, readd (remove and than add) scpriptlet JAR file to classpath and restart Jasper Soft.

Add an existing Android Studio project to GitHub

2015-07-27T13:42:00.000-07:00

At first we should enable the Version Control Integration in our project by pressing "VCS -> Enable Version Control Integration"

In the popup select Git for the version control system and click OK

Now right click on the project and select Git >>> + Add

And then Git >>> Commit Directory

or VCS >>> Commit Changes

In this popup set Commit Message and click Commit

In the next step we will push the changes. For this select VCS >>> Git >>> Push

and we will see next popup

Here click on "Define remote" and enter URL of the GitHub repository and click OK.

Now we will see above popup with data... And click Push...

As result we will we next error on the right top >>> Push rejected

This error is caused, because our repository contains files and we must pull this file as first. Also select VCS >>> Git >>> Pull

In the next popup click on Refresh button (1) then select Branches to merge (2) and click Pull (3).

And now we can repeat Push (VCS >>> Git >>> Push)...

Ready!!!

RS485 >>> pySerial and send data

2015-07-02T07:15:00.001-07:00

Problem:

I implemented a simple program in python for sending data over RS485 bus. Read data from bus was no problem, but send data over bus was without success.

RS485-configuration: 8N1 half-duplex

Solution:

Some boards resolve RTS over hardware, so you can write only ser.write('test') for sending data. But it was not in my case. So I had to set RTS programmatically, also:

ser.setRTS(True)
ser.write('test')
ser.setRTS(False)

VMware Player >>> serial port configuration

2015-06-24T06:33:00.003-07:00

Start VMware Player

1) select the target OS

2) click on 'Edit virtual machine settings' on right side

3) click on 'Add...' button

4) select 'Serial Port'

5) 'Next'

6) select 'Use physical serial port on the host'

7) 'Next'

8) select 'Auto detect' or a specific COM port

Note that to communicate with the VM through this serial port, you will have to connect another machine to the physical serial port (COM1 in this case) using a null modem cable. You cannot just run minicom on that same machine and connect to /dev/ttyS0

9) 'Finish'

10) 'OK'

11) and now 'Play virtual machine'

Ubuntu 14.04 >>> Problem Web + Python + PySerial

2015-06-24T00:17:00.000-07:00

Environment:

VMware Player 7
Ubuntu 14.04
Lighttpd
Python
PySerial

If I ´m trying to open ttyS0 so i become error [Errno 13] Permission denied: '/dev/ttyS0'

To solve this problem check next:

is the user in dialout group?

>>> cat /etc/group | grep dialout

if the user not in dialout group, so add them:

>>> usermod -a -G dialout root
>>> usermod -a -G dialout userXXX
>>> usermod -a -G dialout www-data

add rw-persmission to ttyS0

>>> chmod 666 /dev/ttyS0

Installation of new Linux-image on Toradex Colibri iMX6

2015-06-12T00:31:00.001-07:00

What we need

To create a Linux image we need next things:

Host PC with Linux distribution (best choise is Debian)
Micro SD-card with at least 1GB of free space, formatted with VFAT (FAT32)
A Linux image (can be downloaded here: http://developer.toradex.com/files/toradex-dev/uploads/media/Colibri/Linux/Images/)

Initial preparation:

download and extract the Colibri_iMX6_LinuxImageVx.yz.tar.bz2 package with root permissions.
mkdir /temp/imx6_image
cd /temp/imx6_image
wget http://developer.toradex.com/files/toradex-dev/uploads/media/Colibri/Linux/Images/Colibri_iMX6_LinuxImageV2.4Beta1_20150518.tar.bz2
bunzip2 Colibri_iMX6_LinuxImageV2Beta.tar.bz2
tar xvf Colibri_iMX6_LinuxImageV2Beta.tar

Now we must check availability of next tools. If not available than install this:

mtools
symlinks
parted
awk

As next step we must manipulate update.sh. For this open update.sh

cd /temp/imx6_image/Colibri_iMX6_LinuxImageV2.4
nano update.sh

and search for awk –V. Please replace –V through –W version and save file.

And now we can run the update.sh script with -o argument pointing to the mount point of above mentioned card (at this example SD-card was mounted to /media/toradex)

update.sh –o / media/toradex

If all went well, then next files must be available:

boot.vfat
configblock.bin
flash_blk.img
flash_eth.img
flash_mmc.img
imx6dl-colibri-cam-eval-v3.dtb
imx6dl-colibri-eval-v3.dtb
mbr.bin
root.ext3
u-boot.imx
uImage
versions.txt

Linux image Installation (here we use Iris board)

Connect the serial debug console to UARTA aka FFUART X13 using a null modem RS-232 cable and a 10 pin IDC to 9 pin D-sub male connector (DTK or Intel standard).
Now put micro SD card into the socket (Iris board >>> X10)
Apply power or reset
Hit any key to stop auto booting
Use the ‘run setupdate’ U-Boot command and then
Use the ‘run update’ U-Boot command

READY!!!

Check serial ports under Linux

2015-06-09T00:46:00.006-07:00

If you need to find out serial ports of your board so you can use dmesg for this:

root@colibri-imx6:/# dmesg | grep tty

And now you have for example next output:

[ 0.000000] console [tty1] enabled
[ 0.446753] 2020000.serial: ttymxc0 at MMIO 0x2020000 (irq = 58) is a IMX

Angstrom >>> angstrom-x11-vnc

2015-06-08T23:20:00.003-07:00

Install angstrom-x11vnc-init

opkg update
opkg upgrade
opkg install angstrom-x11vnc-init
reboot

Start x11vnc

x11vnc -display :0

Windows side

On Windows side install and start UltraVNC Viewer. Now put in the field 'VNC Server' the IP of your board + Port 0 (also for example 192.168.155.50:0)

Angstrom >>> install GlassFish

2015-05-21T05:10:00.000-07:00

I found a good instruction on java.net. But it is uncomplete.

Step 0 - 2 are OK.

But now you have to add enviroment variable to end of /etc/profile or ~/.profile.

PATH=/opt/glassfish4/bin:$PATH

As next you have to change permissions of asadmin.

>>>chmod 755 ~/glassfishv4/bin/asadmin

For information:

Default GlassFish Server’s port number: 8080

Default administration server’s port number: 4848

Administration user name: admin; password: none

And now you can forward with step 3...

The start-domain command has an optional domain name parameter, but the default is "domain1":

asadmin start-domain

The domains available are listed with the following command:

asadmin list-domains

Similarly to starting the domain, it can also be stopped with asadmin:

asadmin stop-domain

Angstrom >>> install Oracle JDK

2015-05-20T23:42:00.000-07:00

In the search for "How can i install Oracle JDK on Angstrom" i found this instruction. It is for BeagleBon.

Visit the JDK download page.

For Angstrom, download the "Linux ARM v6/v7 VFP Soft Float ABI" version.
For Debian, download the "Linux ARM v6/v7 Hard Float ABI" version.

Copy jdk-7u40-linux-arm-vfp-*.gz to your BeagleBone Black
Perform 'tar xzf jdk-7u40-linux-arm-vfp-*.gz' to extract the JDK
Perform 'export PATH=$PATH:/home/root/jdk1.7.0_40/bin' to add the JDK to your path
Perform 'export JAVA_HOME=/home/root/jdk1.7.0_40' to set the JAVA_HOME on your installation
Perform 'java -version' to verify your installation

Here i see that need "Linux ARM v6/v7 VFP Soft Float ABI". After all steps i typed "java -version" and had next error:

The cause for this error is that my board has not Software FPU but Hardware FPU... After installation of right version everything worked well...

The next problem i had is that enviroment variables are away after reboot. Also i had to add enviroment variables to my .profile. In BeagleBon .profile is in home directory. But on my board i have only a "system wide .profile" also /etc/profile.

After i changed /etc/profile and reboot everything worked well...

Angstrom >>> set static IP address

2015-05-20T06:53:00.003-07:00

To set static IP address install next connman packages:

connman
connman-angstrom-settings
connman-client
connman-dbg
connman-tests
connman-tools

In the next step get the name of your interface (service). All interfaces (services) you can see under /var/lib/connman. In my case it is ethernet_001523d5a38d8_cable.

Now to set static IP type next line:

$connmanctl config <service> --ipv4 manual  <ip address> <netmask> <gateway>

also for example

$connmanctl config ethernet_001523d5a38d8_cable --ipv4 manual

   192.168.10.101 255.255.254.0 192.168.10.1

Angstrom >>> change keyboard layout

2015-05-20T02:43:00.002-07:00

To set another keyboard layout in console for example to german, use

>>> setxkbmap de

but after reboot the previous keyboard layout is back.

For permanent change you must manipulate /etc/X11/xorg.conf. Add next lines to end of file:

Section "InputClass"
        Identifier "keyboard"
        MatchIsKeyboard "yes"
        Option "XkbLayout" "de"
        Option "XkbVariant" "nodeadkeys"
EndSection

Angstrom >>> install packages

2015-05-20T01:22:00.002-07:00

To install packages under Anstrom make next steps:

- update the list of available packages

>>> opkg update

'opkg' is the default package manager in Angstrom.

To search a package in the list use:

>>> opkg list | grep <package-name>

To install a package use:

>>> opkg install <package-name>

To see if a particular package is installed use

>>> opkg list-installed | grep <package-name>

How To - iterating hashtable in Java

2014-01-10T04:25:00.000-08:00

For iterating hashtable we can use Iterator or Enumeration:

Iterator:

Map<String, String> map = ...

Iterator<Map.Entry<String, String>> it = map.entrySet().iterator();

while (it.hasNext()) {
Map.Entry<String, String> entry = it.next();

String key = entry.getKey();
String val = entry.getValue();
...
}

Enumeration:

Map<String, String> map = ...

Enumeration<String> enumKey = map.keys();
while(enumKey.hasMoreElements()) {
    String key = enumKey.nextElement();
    String val = map.get(key);
    ...
}
