window handle

WindowFromPoint PROTO :DWORD,:DWORD

The win32.hlp file is misleading here, you put the 2 co-ordinates in the 2 DWORD parameters. To get the screen co-ordinates, I think you need to use SetCapture and trap the WM_MOUSEMOVE message to get the co-ordinates. This will involve converting them between client and screen co-ordinates with the two conversion functions, ScreenToClient() and ClientToScreen() Regards, hutch@pbq.com.au edit added code tags This message was edited by Hiroshimator, on 2/16/2001 7:48:20 PM
