OnIdle() doesn't work

I've a problem with the CApp::OnIdle()-routine:

In my SDI-App I installed an OnIdle() that works perfectly. Now I want to show a fullscreen-animation after a button is pushed and I want to use the OnIdle -routine to check for updating the (full) screen (20Hz or so). Therefore I create a new Wnd (with WS_POPUP|WS_MAXIMIZE|WS_VISIBLE style and all the stuff) and draw a bitmap to it. That's ok. But from then on my OnIdle() won't be called unless I move the mouse or press a key. As far as I found out this behaviour depends on the size of the created Wnd. If the mouse isn't in the client-area of the new Wnd during the creation, OnIdle is called. But only as long as I don't move the mouse(!) (no matter if inside or outside the new Wnd). Keypressing is ok.

Has anyone an idea of how to work around that?

Thanks

OnIdle will only be called while you return TRUE.

The other possibility would be to create a timer and use WM_TIMER to do your animation.

Excellent! I returned CWinApp::OnIdle(lCount)
as suggested by the class-wizzard. (Another example of "You better don't rely on things like class-wizzard if you haven't coded the stuff by hand yet and know exactly what's going on".)

btw OnTimer is too slow for animations....
