Hey,
I seem to be having problems where the view is drawing over a pane when its dynamically popped up (Unpinned).
Its an SDI application. The application's view receives refresh messages about once a second and repaints itself.
When I unpin the pane but have it visible, the main view draws over both the pane frame and the contents of the pane. I have created the contents of the pane with WS_CLIPSIBLINGS but that made any difference.
Any pointers?

1) Need WS_CLIPCHILDREN too!
2) Be sure you're only painting in OnPaint() or OnDraw(), and using the provided HDC/CDC.

Hi,
Thanks for the fast reply!
The CWnd Objects that sit in my pane, are created with the WS_CLIPCHILDREN and WS_CLIPSIBLINGS styles. However this doesn't seem to change anything. The Docking pane frames themselves are created with these Styles (In the DockingPaneManager I think) but they too are still getting overdrawn.
The painting is done in OnPaint using a PaintDC. However it is all refreshed by a function in the Mainframe that calls RedrawWindow for the view.

Does your frame window use a splitter window, by any chance?

You say "a paint DC," are you sure it's the one for the window you're painting; i.e.:
void CMyWnd::OnPaint()
{
CPaintDC dc(this);
//etc//
}
