Windows messages

[Nick]

Hi There,

I'm just trying to find a range of Windows values that are unused? I
was previously using 500's but this has started to cause issues, is there a
range of values that are unused? I would rather not have to resort to
WM_USER or whatever to value is for *custom* messages. Thanks loads in
advance!!!

i suggest you go above 0x8000 (WM_APP). too much going on at 0x400
(WM_USER). 500's (near 0x200) are in the range owned by windows, so you are
asking for trouble there.

WinAPI SDK suggests to use WM_USE + your value for your custom
messages.

If I append a menu item to the system menu & handle the click event in
WndProc, I always start at 1000
