Javascript to generate Query String

For my future reference, I know that I will need this later on.

function create_request_string(theForm)
{
var reqStr = "";

for(i=0; i < theForm.elements.length; i++)
{
isFormObject = false;

switch (theForm.elements[i].tagName)
{
case "INPUT":

switch (theForm.elements[i].type)
{
case "text":
case "hidden":
reqStr += theForm.elements[i].name + "=" + encodeURIComponent(theForm.elements[i].value);
isFormObject = true;
break;

case "checkbox":
if (theForm.elements[i].checked)
{
reqStr += theForm.elements[i].name + "=" + theForm.elements[i].value;
}else{
reqStr += theForm.elements[i].name + "=";
}
isFormObject = true;
break;

case "radio":
if (theForm.elements[i].checked)
{
reqStr += theForm.elements[i].name + "=" + theForm.elements[i].value;
isFormObject = true;
}
}
break;

case "TEXTAREA":

reqStr += theForm.elements[i].name + "=" + encodeURIComponent(theForm.elements[i].value);
isFormObject = true;
break;

case "SELECT":
var sel = theForm.elements[i];
reqStr += sel.name + "=" + sel.options[sel.selectedIndex].value;
isFormObject = true;
break;
}

if ((isFormObject) && ((i+1)!= theForm.elements.length))
{
reqStr += "&";
}

}

return reqStr;
}

My first blackberry application. MyLampu

Previously, I’m having a problem to run my apps on blackberry device. It’s giving me attempts-to-access-a-security-api-error. After getting my BlackBerry JDE Signature key, now I can run it without a problem.

In Eclipse, it will show something like below. We can see the required RIM Runtime API(RRT) has been signed

MyLampu is a simple application where it starts the video camera, and the flash light comes on immediately.

It’s something like a torchlight.

It’s cool right ? you can write your own Java code and communicate with your blackberry device

p/s: anyone into blackberry programming ?

p/s: I’m having a very big problem in my life…but I won’t blog it here.. Perhaps time will be my best medicine.Good luck to me.

Advance Shell Command – Remove .svn folders in Windows.

If you are using subversion source control, you should know that there are hidden folders named .svn inside your project. If you need to deploy the apps to the server, you should consider to remove all the .svn folder first.

Thanks to Jon Galloway. I found out the easiest way to do that.

Step 1. Copy below code, put it into the file and name it to whatever.reg

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Folder\shell\DeleteSVN]
@="Delete SVN Folders"

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Folder\shell\DeleteSVN\command]
@="cmd.exe /c \"TITLE Removing SVN Folders in %1 && COLOR 9A && FOR /r \"%1\" %%f IN (.svn) DO RD /s /q \"%%f\" \""

Step 2. Right click the file and merge.

How to change SVN URL in Eclipse

For whatever reason, sometimes you will need to change your SVN URL. Perhaps you need to place the server to a new building and change the ip address. After the changes, you cannot commit to that server using your eclipse.
