MFC如何把增强元文件复制到剪接板

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::OnEditCopyWmf()
{
        tagSTGMEDIUM * data;
        CClientDC dcRef( this );
        data = new tagSTGMEDIUM;
        CMetaFileDC * dcMeta;
        dcMeta = new CMetaFileDC();
        COleDataSource* pData = new COleDataSource;
        CRect lmbr;
        GetClientRect(lmbr);
        //replace "ImageName" with a description of this image
        dcMeta->CreateEnhanced(&dcRef, NULL, NULL,"ImageName\0Copy\0\0" );
        dcMeta->SetMapMode(MM_TEXT);
        //actually draw to the device context
        OnDraw(dcMeta);
        //done drawing
        data->tymed = TYMED_ENHMF;
        data->hEnhMetaFile = dcMeta->CloseEnhanced();
        pData->CacheData( CF_ENHMETAFILE, data );
        pData->SetClipboard();
        delete dcMeta;
        delete data;
}
