VS2010 Single Document MFC by loading bitmap files as client area background

Implementation results:

This is actually a very common function, everyone will consider to their own simple project to do a background interface. In fact, just overload the OnEraseBkgnd () function in the view class.

The code is as follows:

BOOL Cdddview:: OnEraseBkgnd(CDC*PDC) {//TODO: Add the Message Handler code and/or call the default value hereCStringstring("B.bmp"); Hbitmap Hbitmap=(HBITMAP):: LoadImage(AfxGetInstanceHandle (),string, Image_bitmap,1024x768,768, lr_createdibsection|Lr_loadfromfile);//very Important:not Call the SUPER CLASS FUNCTIONCPAINTDC DC (this);if(Hbitmap==NULL)return FALSE;     CBitmap bitmap; Bitmap.Attach (HBITMAP);     BITMAP bmp; Bitmap.Getbitmap (&BMP);    CDC MEMDC; Memdc.CreateCompatibleDC (PDC); CBitmap*Poldbitmap=Memdc.SelectObject (&Bitmap);    CRect rect; GetClientRect (&RECT); Pdc -Setstretchbltmode (Coloroncolor);//This mode does not set the words can cause serious distortion of the picturePdc -STRETCHBLT (0,0, rect.Width (), rect.Height (),&MEMDC,0,0Bmp.Bmwidth,bmp.Bmheight,srccopy); Memdc.SelectObject (POLDBITMAP); Memdc.DeleteDC ();//Remove DC    return TRUE; }

By the way, change the title bar of the project:

BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs){    if!CFrameWndEx::PreCreateWindow(cs) )        returnFALSE;    // TODO: 在此处通过修改    //  CREATESTRUCT cs 来修改窗口类或样式    cs.&=~FWS_ADDTOTITLE;    cs.= _T("XXX系统");    returnTRUE;}

There may be some formatting problems when loading bitmaps, here are the discussion stickers:
