Developing Hello World Application in Blackberry

Those have experience in .net and are new to mobile application development, will find this article useful for developing your first application on blackberry mobile.

For developing blackberry mobile application you need to have pre-requisite installed on your computer (see my other article for installing pre-requites for blackberry development).

For short, you should have installed :

• Blackberry plug-in for Visual Studio 2005/2008

If you have this plug-in in your visual studio then move ahead.

Step 1.

• Open Visual Studio
• On File Menu-> New Project
• Select Blackberry from left panel -> Blackberry MDS Runtime Application
• Name your application to BlackberryHelloWold

Note: Please remember when you'll click OK "MDS development server" will start in system tray.

You'll see blackberry mobile screen available on your visual studio along with blackberry controls onto the left side.

Step 2.

• Drag a TextBox from the toolbox to the blackberry form
• Click right button of mouse on TextBox and select Properties
• In Properties window (right side), change name to txtName
• Now drag a button and drop it to the form just below the txtName (TextBox)
• Change its name to btnOK
• Change its Text to OK from Property window
  
• Double click on the button (btnOK)
• Form1_btnOK_Click() will be appeared in .js file (this creates .js file not cs file) and write the following in for display text in dialog box.

function Form1_btnOK_Click()
{
    Dialog.display(Form1.txtName.value);
}

• Now Run your application (just click play symbol available in your visual studio)

This will start simulator (Just Looks like that you are running your application in mobile). Wait for some time your application will be loaded automatically.

Note: please check with Symentic Client Firewall this should not block your ports, otherwise your application will stuck and will not be run.
