>把文本放置到剪接板上： CString source; //put your text in source if(OpenClipboard()) { HGLOBAL clipbuffer; char * buffer; EmptyClipboard(); clipbuffer = GlobalAlloc(GMEM_DDESHARE, source.GetLength()+1); buffer = (char*)GlobalLock(clipbuffer); strcpy(buffer, LPCSTR(source)); GlobalUnlock(clipbuffer); SetClipboardData(CF_TEXT,clipbuffer); CloseClipboard(); } 从剪接板上获取文本： char * buffer; if(OpenClipboard()) { buffer = (char*)GetClipboardData(CF_TEXT); //do something with buffer here //before it goes out of scope } CloseClipboard();
<DIV class=tc>HANDLE GetClipboardData(UINT Form) Form为剪贴板数据格式 CF_TEXT为文本数据格式,也可以是图形数据格式或其它定义的数据格式， 返回值为剪的板数据的内存控制句柄，如果为NULL表示地址无效。</DIV>

给你一个完整代码好了 CDC* pDC = GetDC();//获得DC OnPrepareDC(pDC);//设置DC的滚动属性，与ScollView的滚动有关 UINT m_cfDraw=RegisterClipboardFormat("Draw_zgj"); CBase *m_usrCurrentObject; CGraphDoc* pDoc = GetDocument(); COleDataObject dataObject; //连接剪贴板 dataObject.AttachClipboard(); if (dataObject.IsDataAvailable(m_cfDraw)) //判断指定的格式是否存在 { //得到内存文件指针 CFile* pFile = dataObject.GetFileData(m_cfDraw); if (pFile != NULL) { //建立用于读取的文档对象 CArchive ar(pFile, CArchive::load); TRY { //针对ar,调用对象的序列化函数。 pDoc->m_CopyaObjects.Serialize(ar); } CATCH_ALL(e) { ar.Close(); delete pFile; THROW_LAST(); } END_CATCH_ALL ar.Close(); delete pFile;//关键是这里，利用内存文件 } } int xoffset=0,yoffset=0; int i; m_usrCurrentObject = pDoc->m_CopyaObjects[0]; xoffset=PastePoint.x-m_usrCurrentObject->m_x1; yoffset=PastePoint.y-m_usrCurrentObject->m_y1; for(i = pDoc->m_CopyaObjects.GetSize()-1; i >= 0; i--) { m_usrCurrentObject = pDoc->m_CopyaObjects; m_usrCurrentObject->m_x1+=xoffset; m_usrCurrentObject->m_x2+=xoffset; m_usrCurrentObject->m_y1+=yoffset; m_usrCurrentObject->m_y2+=yoffset; } if(pDoc->m_CopyaObjects.GetSize()>300&&pDoc->m_aObjects.GetSize()>300){AfxMessageBox("粘贴大量元件会造成程序长时间无响应");return;} CopyToArray(&pDoc->m_CopyaObjects,&pDoc->m_aObjects,0); CopyToArray(&pDoc->m_CopyaObjects,&pDoc->m_TemplateObjects,1); //MoveSelGraph(&pDoc->m_CopyaObjects,point1.x,point1.y,5); Invalidate();
