Dialog Box WM_PAINT problem

[Elbios]

1. 0% CPU means that app does nothing, so noting happens and nothing changes...

well i meant 0-1% because the app won't require more, obviously 25% is ridiculous for such an app which makes me think that the WM_PAINT message is being repeatedly sent by the OS (why?)

2. WM_PAINT message is sent from Windows to your App window ... when the system or another application makes a request to paint a portion of an application's window. So if you ignore this request and do nothing - northing is shown!

I see, but how should I handle this request exactly?
