You should put the 'detecting part' of your program on a worker thread in order to keep the GUI responsive. Have a look at Threading (MSDN)[^].

The way I would do it is to create a form which holds the message and which either does the GetProcesses in a background thread or in the Shown event handler (background is better) and closes when it is done.
You then use ShowDialog on the message form in your main form and it returns when the form closes so you can get the result.

does the back ground be attach to the form.cs Designer like the way we do as Load,click,KeyDown,KeyPress,FormClosed,FormClosing,Enter in the property menue or is it just a method like

private void backgroundWorker1_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
// This method runs on the main thread.
Words.CurrentState state =
(Words.CurrentState)e.UserState;
this.LinesCounted.Text = state.LinesCounted.ToString();
this.WordsCounted.Text = state.WordsMatched.ToString();
}
?
