So there is no need to override OnNcPaint, you can do all of the painting in OnPaint void CMainFrame::OnPaint()
When using DwmExtendFrameIntoClientArea, it means frame is extended in to client area. I want to remove the unknown title bar without any side effect.ĭoes anyone could provide me a good solution or suggestion? Furthermore, my program cannot capture the minimum, maximum and the close button message on my custom caption bar anymore. If I remove WS_THICKFRAME, the unknown cation bar will disappear, but I cannot resizing the border of my window. I found out the unknown caption is caused by WS_THICKFRAME in the cs.style. However, my window appears another unknown caption title bar under Windows 10.
