Only one application instance

[Jose Fco Bonnin]

Hi, I would like to check if there is running any instance of my application, in order to set the focus on it if the user try to start a new one. Any idea? Thank you.

Something like this:

Int32 RunningProcesses = Process.GetProcessesByName(Process.GetCurrentProcess().ProcessName ).Length;
if ( RunningProcesses >= 1 ) {
MessageBox.Show( "already running the program" );
}
