bmp.LoadBitmap(IDB_BITMAP7);
bmp.GetBitmap(&bmpInfo);

pOldBmp = dcMemory.SelectObject(&bmp);

x = bmpInfo.bmWidth;
y = bmpInfo.bmHeight;

lrBorderWidth = ( x > m_nFrameWidth+m_nBorderWidth ) ? x : m_nFrameWidth+m_nBorderWidth;

winDC.StretchBlt( 0,m_nCaptionHeight,lrBorderWidth,winRC.Height()-m_nCaptionHeight,&dcMemory,0,0,x,y,SRCCOPY );
winDC.StretchBlt( winRC.Width()-lrBorderWidth,m_nCaptionHeight,lrBorderWidth,
winRC.Height()-m_nCaptionHeight,&dcMemory,0,0,x,y,SRCCOPY);

dcMemory.SelectObject(pOldBmp);
bmp.DeleteObject();

推荐答案

您必须处理所有其他NC ..消息(WM_NCCALCSIZE，WM_NCPAINT，WM_NCHITTEST等).如何处理它们，请阅读SDK文档.为了防止圆角的Window布局，应将窗口区域设置为0(SetWindowRgn(0)).
问候.

You have to handle all the other NC.. messages (WM_NCCALCSIZE, WM_NCPAINT, WM_NCHITTEST and so on). How to handle them read the SDK documentation. To prevent the roundrect Window layout you should set the window region to 0 (SetWindowRgn(0)).
