COM Container for office file
-
Hi, All... I am writing a COM container using MFC OLE classes. The purpose of the container is to display and/or print MS Word doc as portion of a bigger display/plot. For this I am trying to get the Enhance Metafile representation of the word doc file using MSWord as COM Server. I have had limited success in the sense that only first page of the document is visible in the metafile. Here is what I have tried: CMyContainerDoc* pDoc = new CMyContainerDoc; //derived from COleDocument CMyCtrlItem* pCtrlItem = new CMyCtrlItem(pDoc); //derived from COleClientItem pCtrlItem->CreateFromFile("mytestfile.doc"); //path and name of a MS word file CSize clientSize; BOOL bRet = pCtrlItem->GetCachedExtent(&clientSize, DVASPECT CONTENT); HDC hDC = ::CreateEnhMetaFile(NULL, "c:\\drawtest.emf", 0, NULL); CDC::FromHandle(hDC)->HIMETRICtoLP(&clientSize); CRect rect( 0, 0, clientSize.cx, clientSize.cy); pCtrlItem->Draw(CDC::FromHandle(hDC), &rect, DVASPECT CONTENT); HENHMETAFILE hMetaFile = CloseEnhMetaFile( hDC ); DeleteEnhMetaFile( hMetaFile); This results in just the first page of document to be represented in the metafile. How could I get the whole document in the metafile? 2. Alternatively, I tried to use GetData function of IDataObject interface . It returns success status code, but when I try to use the metafile handle, returned through STGMEDIUM structure, it still contains only the first page. Here is the relevant code: FORMATETC fmtetc; fmtetc.cfFormat = CF METAFILEPICT; fmtetc.dwAspect = DVASPECT CONTENT; fmtetc.ptd = NULL; fmtetc.tymed = TYMED MFPICT; fmtetc.lindex = -1; STGMEDIUM stgMed; memset(&stgMed, 0, sizeof(stgMed)); LPDATAOBJECT lpDataObject = 0; pCtrlItem->m lpObject->QueryInterface(IID IDataObject, (void**)&lpDataObject); sc = lpDataObject->GetData( &fmtetc, &stgMed ); LPMETAFILEPICT pMF = (LPMETAFILEPICT)GlobalLock(stgMed.hEnhMetaFile); //Draw the picture. HDC hDC2 = ::CreateEnhMetaFile(NULL, "c:\\testGetdata.emf", 0, NULL); BOOL bRetPlay = PlayMetaFile(hDC2, pMF->hMF); GlobalUnlock(stgMed.hEnhMetaFile); ReleaseStgMedium(&stgMed); HENHMETAFILE hMetaFile = CloseEnhMetaFile( hDC2 ); DeleteEnhMetaFile( hMetaFile ); Here again, the metafile testGetData.emf contains just the first page of the document. Is there something I am missing here? Or if there is another better way of achieving the intended results. any suggestion appriciated ! Thanks in Advance Vishal
