标题: MFC如何把位图放置到剪接板上
实现步骤如下：

(1) 如果工程还没有支持OLE，添加下面代码：
#include <afxole.h>

并在初始化中添加下面代码：
OleInitialize(NULL);

(2) 下面代码将视的位图放置到剪接板上

void CMyView::OnEditCopy()
{

COLORREF BACKGROUND_COLOR = RGB(255,255,255);
tagSTGMEDIUM * data;
CBitmap * junk;
COleDataSource* pData = new COleDataSource;
data = new tagSTGMEDIUM;
junk = new CBitmap();
CClientDC cdc(this);
CDC dc;
dc.CreateCompatibleDC(&cdc);
CRect client;
//replace this with something that calculates
//the proper rectangle size
GetClientRect(client);
junk->CreateCompatibleBitmap(&cdc,client.Width(),client.Height());
dc.SelectObject(junk);
CBrush fill(BACKGROUND_COLOR);
dc.FillRect(client,&fill);
//replace this with something that draws to a CDC
OnDraw(&dc);
data->tymed = TYMED_GDI;
data->hBitmap = HBITMAP(*junk);
pData->CacheData( CF_BITMAP, data );
pData->SetClipboard();
delete data;
delete junk;

}
