Thank you, Steve - I see, you include the editor, too :thumbu

I'm wondering why do you preserve ebx in MsgLoop? :wink Should be:
MsgLoop proc
LOCAL msg:MSG
; push ebx
lea ebx, msg
; jmp getmsg
msgloop:
invoke TranslateMessage, ebx
invoke DispatchMessage, ebx
;getmsg:
invoke GetMessage,ebx,0,0,0
test eax, eax
jnz msgloop
; pop ebx
ret
Lingo,
EBX is specified in the Intel ABI as needing to be preserved.
This would be the preferred code form if it in fact mattered. I have seen problems in the past with not calling GetMessage() before the other two calls so I ensure it runs first.
MsgLoop proc
LOCAL msg:MSG
push ebx
lea ebx, msg
invoke GetMessage,ebx,0,0,0
msgloop:
invoke TranslateMessage, ebx
invoke DispatchMessage, ebx
invoke GetMessage,ebx,0,0,0
test eax, eax
jnz msgloop
pop ebx
ret
MsgLoop endp
Only CALLBACK procs, specified by the MSDN, need preserving the EBX,ESI,EDI registers if you will modify them...but MsgLoop and Main are not CALLBACK procs! :wink
i am sure this is something simple

Thanks Hutch.
The demo also works on XP Home Edition Sp2.
