when a window is repainted, the child controls in it disappear.To prevent this I use: INVOKE SendMessage, WM_PAINT,ChildControl_handle, hDC,0 Is this correct or there is another way. Thanks. A nada
The parent window should have WS_CLIPCHILDREN as part of its style. This is automatic for WS_OVERLAPPED. I don't remember if it's true for WS_POPUP.
