inserting bmp in file
-
I am using folowing code to insert BMP in RichEdit. InsertPlotBitmap(CString szFileName) { USES_CONVERSION; SCODE sc = ::CreateILockBytesOnHGlobal(NULL, TRUE, &m_lpLockBytes); if (sc != S_OK) AfxThrowOleException(sc); ASSERT(m_lpLockBytes != NULL); sc = ::StgCreateDocfileOnILockBytes(m_lpLockBytes, STGM_SHARE_EXCLUSIVE|STGM_CREATE|STGM_READWRITE, 0, &m_lpStorage); if (sc != S_OK) { VERIFY(m_lpLockBytes->Release() == 0); m_lpLockBytes = NULL; AfxThrowOleException(sc); } // CString szFileName=strSmile; // attempt to create the object sc = ::OleCreateFromFile(CLSID_NULL, T2COLE(szFileName), IID_IUnknown, OLERENDER_DRAW, NULL, NULL, m_lpStorage, (void **) &m_lpObject); if ( sc != S_OK ) { TCHAR * lpMsgBuf; ::FormatMessage( FORMAT_MESSAGE_ALLOCATE_BUFFER | FORMAT_MESSAGE_FROM_SYSTEM, NULL, ::GetLastError(), MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), (LPTSTR) &lpMsgBuf, 0, NULL ); CString msg( lpMsgBuf ); msg += _T("\n\n\n" ); msg += szFileName; AfxMessageBox( msg, MB_OK ); ::LocalFree( lpMsgBuf ); return; } // m_lpObject is currently an IUnknown, convert to IOleObject if (m_lpObject != NULL) { LPUNKNOWN lpUnk = m_lpObject; m_lpObject = QUERYINTERFACE(lpUnk, IOleObject); lpUnk->Release(); if (m_lpObject == NULL) AfxThrowOleException(E_OUTOFMEMORY); } // cache the IViewObject interface m_lpViewObject = QUERYINTERFACE(m_lpObject, IViewObject2); if (m_lpViewObject == NULL) return; // setup for advises; we assume that OLE cleans them up properly LPADVISESINK lpAdviseSink = (LPADVISESINK)GetInterface(&IID_IAdviseSink); // set up view advise VERIFY(m_lpViewObject->SetAdvise(DVASPECT_CONTENT, 0, lpAdviseSink) == S_OK); // the server shows these in its user-interface // (as document title and in File Exit menu) m_lpObject->SetHostNames(T2COLE(AfxGetAppName()), T2COLE(_T("Test"))); // all items are "contained" -- this makes our reference to this object // weak -- which is needed for links to embedding silent update.
