need help to create transparent child window

[jennico]

from msdn: Flicker-free painting

Without WS_EX_COMPOSITED, flicker caused by a lot of child controls bothers me.

Enabling WS_EX_COMPOSITED ex-style bit makes flicker gone, but it causes 100% cpu load.

well, for me it does not raise cpu load, so WS_EX_COMPOSITED seems to be an excellent style to create layered child guis without flickering !!!!

thank you very much !

edit: btw why does it move faster when i move the mouse ????

When you move the mouse, the GUI receives mouse move messages. Depending on how your code is written, you may be picking them up for redrawing. There are many programs that it seems to happen to.
