[resolved] [2.0] findwindow explanation

[cdubb07]

hi all, i was hoping that someone could explain findwindow to me and possibly give me an example on how to use it to bring a window "to front"? thanks

top of your code window ...

[COLOR=Blue]using[/COLOR] System.Runtime.InteropServices;

to use FindWindow ...

[[COLOR=Green]DllImport[/COLOR]([COLOR=Purple]"user32.dll"[/COLOR], EntryPoint = "FindWindowA")]
        [COLOR=Blue]private static extern[/COLOR] [COLOR=Green]IntPtr[/COLOR] FindWindow([COLOR=Blue]string[/COLOR] lpClassName, [COLOR=Blue]string[/COLOR] lpWindowName);
        [[COLOR=Green]DllImport[/COLOR]([COLOR=Purple]"user32.dll"[/COLOR])]
        [COLOR=Blue]private static extern int[/COLOR] BringWindowToTop([COLOR=Green]IntPtr[/COLOR] hwnd);
 
        [COLOR=Blue]private void[/COLOR] button1_Click([COLOR=Blue]object[/COLOR] sender, EventArgs e)
        {
            [COLOR=Green]/// in this case an open instance of Notepad in the background[/COLOR]
            [COLOR=Green]IntPtr[/COLOR] hwnd = FindWindow([COLOR=Purple]"Notepad"[/COLOR], [COLOR=Blue]null[/COLOR]);
            [COLOR=Green]/// if you have retreived a valid handle ...[/COLOR]
            [COLOR=Blue]if[/COLOR](!hwnd.Equals([COLOR=Green]IntPtr[/COLOR].Zero))
            {
                BringWindowToTop(hwnd);
            }
        }

I can't get this to work with any other program but Notepad, can somebody help?

You're probably using the wrong class name. See gigemboy's signature for a tool (WinID) that will allow you to determine the class name of an open window or else use Spy++.
