You can easily handle the WM_PAINT standard windows message in the WindowProc() virtual method of your CExtResizablePropertyPage-derived class: LRESULT CYourPropertyPage::WindowProc(
UINT message, WPARAM wParam, LPARAM lParam )
{
if( message == WM_PAINT )
{
CRect rcClient;
GetClientRect( &rcClient );
CPaintDC dcPaint( this );
CExtMemoryDC dc( &dcPaint, &rcClient );
bool bTransparent = false;
if( g_PaintManager->GetCb2DbTransparentMode( this ) )
{
CExtPaintManager::stat_ExcludeChildAreas(
dc,
GetSafeHwnd(),
CExtPaintManager::
stat_DefExcludeChildAreaCallback
);
if( g_PaintManager->PaintDockerBkgnd( true, dc, this ) )
bTransparent = true;
} // if( g_PaintManager->GetCb2DbTransparentMode( this ) )
if( ! bTransparent )
dc.FillSolidRect(
&rcClient,
g_PaintManager->GetColor(
CExtPaintManager::CLR_3DFACE_OUT,
this
)
);
///////////////////////////////////////////////////

return 0;
} // if( message == WM_PAINT )
return
CExtResizablePropertyPage::
WindowProc( message, wParam, lParam );
}
