This can be achieved by windows api's

Add the definitions inside your class

[DllImportAttribute( "User32.dll" )]
private static extern int FindWindow( String ClassName, String
WindowName );
[DllImportAttribute( "User32.dll" )]
private static extern int SetForegroundWindow( int hWnd );


//to activate an application
int hWnd = FindWindow( null, "This is my Application Title" );
if( hWnd > 0 )
{
SetForegroundWindow( hWnd );
}

This is approach will not work when at user desktop there is an explorer
window open with same title as your application title.

Manish,

Multiple instances of same application will have same titiles. To over come
this, we have to get process ids, to identify which one we want to activate.

for example

Process [] apps = Process.GetProcessesByName("TestAppName")

Now if we decide which one we want from this process list to be activated,
pass the handle to SetForegroundWindow() function to activate it.

example:

SetForegroundWindow(app[0].Handle.ToInt32 ()); //assuming that 1st process
id is the one we want to activate.
