标题: 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;
}
