Have you looked into SetWindowLong/GetWindowLong and also (believe
it or not SetClassLong/GetClassLong). I seem to remember that solving a
similar issue with SetClassLong one time.
If not, you may be into WM_NCPAINT, e.g....
case WM_NCPAINT:
{
HDC hdc;
hdc = GetDCEx(hwnd, (HRGN)wParam, DCX_WINDOW|DCX_INTERSECTRGN);
// Paint into this DC
ReleaseDC(hwnd, hdc);
}
