在文档视图结构里面的view里面有OnDraw()函数吧
CBitmap bitmap;
HBITMAP hbitmap;
hbitmap = ::LoadImage("*.bmp",IMAGE_BITMAP,NULL,LR_LOADFROMFILE);//可能有几个参数不对,查一下就好了OnDraw(CDC* pDC)
{
    bitmap.attach(hbitmap);
    CDC memdc;
    CRect rect;
    GetClientRect(&rect);
    memdc.CreateCompatibleDC(pDC);
    memdc.SelectObject(&bitmap);
    pDC->BitBlt(0,0,rect.right,rect.bottom,&memdc,0,0,SRCCOPY);
}

回复人： stoneywang(喜欢飞) :显示不出来啊！
//CBitmap bitmap;
//HANDLE  hbitmap;
//hbitmap = ::LoadImage(NULL,
//   "f:\\a1.bmp",
//   IMAGE_BITMAP,
//   NULL,
//   NULL,
//   LR_LOADFROMFILE);
    bitmap.LoadBitmap("f:\\a1.bmp");    CDC memdc;
    CRect rect;
    GetClientRect(&rect);
    memdc.CreateCompatibleDC(pDC);
    memdc.SelectObject(&bitmap);
    pDC->BitBlt(0,0,rect.right,rect.bottom,&memdc,0,0,SRCCOPY);

bitmap.LoadBitmap("f:\\a1.bmp");如果要选择图片，应该使用LoadImage

就用LoadImage不行么?里面参数设置也很简单的,我是有点不记得了

VCKBASE上代码到是很多，不过还是看看相关知识的比较好

你可以用SetDIBToDevice（）啊，这个函数很好用的。偶用的挺好的。

LoadImage與LoadBitmap都可以資源名稱的圖片，但僅僅LoadImage可以直接使用圖片的地址信息來讀取

具體代碼如下:
     // HDRAWDIB m_hDrawDIB;
//#include <Vfw.h>
         m_hDrawDIB = DrawDibOpen();  //
if(m_hDrawDIB)
{
DrawDibStart(m_hDrawDIB,25);
}         CBitmap bmp;
BITMAP bitmap;
HBITMAP hbitmap = NULL;
CRect rect; GetClientRect(&rect);

HDC dc = ::GetDC(m_hWnd);
hbitmap = (HBITMAP)::LoadImage( AfxGetResourceHandle(),
MAKEINTRESOURCE(IDB_PIC), IMAGE_BITMAP, 0, 0,////IDB_PIC未需要加載的資源
LR_CREATEDIBSECTION | LR_DEFAULTSIZE /*| LR_LOADFROMFILE*/ );
bmp.Attach(hbitmap);

bmp.GetBitmap(&bitmap);

BITMAPINFOHEADER hdr;
ZeroMemory(&hdr,sizeof(BITMAPINFOHEADER));
hdr.biSize = sizeof(BITMAPINFOHEADER);
hdr.biHeight = bitmap.bmHeight;
hdr.biWidth = bitmap.bmWidth;
hdr.biPlanes = 1;
hdr.biBitCount = bitmap.bmBitsPixel;
hdr.biCompression = BI_RGB;
hdr.biSizeImage = 0;//bitmap.bmWidth*bitmap.bmHeight*(hdr.biBitCount >> 3);
hdr.biXPelsPerMeter = 0;
hdr.biYPelsPerMeter = 0;
hdr.biClrUsed = 0;
hdr.biClrImportant = 0;

DrawDibDraw(m_hDrawDIB,dc,
0,0,
rect.Width(),
rect.Height(),
&hdr,
bitmap.bmBits,
0,0,-1,
-1,
DDF_SAME_HDC);

bmp.Detach();
::ReleaseDC(m_hWnd,dc);
::DeleteObject(hbitmap);

OnDraw(CDC* pDC)
{
    CBitmap bitmap;
    HBITMAP hbitmap;
    hbitmap = (HBITMAP)LoadImage(NULL,"*.bmp",IMAGE_BITMAP,0,0,LR_CREATEDIBSECTION|LR_DEFAULTSIZE|LR_LOADFROMFILE);
    bitmap.attach(hbitmap);
    CDC memdc;
    CRect rect;
    GetClientRect(&rect);
    memdc.CreateCompatibleDC(pDC);
    memdc.SelectObject(&bitmap);
    pDC->BitBlt(0,0,rect.right,rect.bottom,&memdc,0,0,SRCCOPY);
}这样绝对可以显示位图,要求不高的话,这个就将就着用把
