Hello guys. When I have some kind of painting which regularly change in a MDI window (like simple colorful rectangles) and a docking pane attached to this window in auto hide mode I get the following results:
At the moment when the pane expands (shows) by pressing the tab button the colored rectangles are drawn straight trough the pane and scrabbles it. The pane is not redrawn until it doesn't hide. Attached modified one of the original samples

Please help me to fix this problem?

void CMDIPanesView::OnTimer(UINT nIDEvent)
{
// TODO: Add your message handler code here and/or call default
m_color = RGB(rand()%255, rand()%255, rand()%255);

Invalidate(false);
}

Add clip styles to your view:

BOOL CMDIPanesView::PreCreateWindow(CREATESTRUCT& cs)
{
cs.style |= WS_CLIPCHILDREN|WS_CLIPSIBLINGS;

return CView::PreCreateWindow(cs);
}

Thanks a lot for your help. It works ok now. I actually saw the same recommendation in another post and tried it but without success because i did not put the code on the right place.
