help with WM_CREATE

[zhao]

I want to show a msgbox when one program create a window,but my code does not work.

#include <GUIConstants.au3>
Global Const $WM_CREATE = 0x1

GUIRegisterMsg($WM_CREATE, "MY_WM_CREATE")

while 1
wend

Func MY_WM_CREATE($hWnd, $Msg, $wParam, $lParam)
MsgBox(0,"","someone create a window")
EndFunc   ;==>MY_WM_CREATE

And I want to get the handle of the new window ,but I still have no ideas.

As I can know GUIRegisterMsg() works with YOUR GUI windows.

So use WinList and/or WinExists functions ...
