Question about WM_xxx Messages

[Zaph-0]

Hi,

is there a certain range where I can define my WM_xxx messages without causing any problems to windows messagehandlers ?

How about > 1000000 ?

Have a look at WM_USER+x:

Just a small remark...in general you can use both 'WM_USER' or 'WM_APP' for user-defined messages. However, you should rather use 'WM_APP' as a base for your user-defined messages since it provides less problems. Windows itself uses the range 'WM_USER + x' for several messages therefore you can run into conflict problems pretty easy...

Thanx for the additional info!
