Hi,

I'm writing a program to copy files, and i would like to prevent windows-shutdown while copying. Basicly I know that a WM_QUERYENDSESSION message is sent to every window running.

I catch the message in the WinProc but to prevent my window and the OS from shutting down i have to return FALSE on the message. My question is how to do that (DefWindowProc returns TRUE for this Message). I tryed ReplyMessage, retn 0 but nothing works.

Thanks in advance.

Code:
mov eax, 0 ; or "xor eax, eax"
ret ; or "jmp .exitProc"
