调用PowerPoint的Dispatch接口，将PPT装换为图片

//首先导入一堆的东西 #import "MSO9.DLL" named_guids, rename("RGB", "MsoRGB") #import "VBE6EXT.OLB" #import "MSPPT9.OLB" \ rename("RGB", "MsoRGB") \ rename("DialogBox", "MsoDialogBox") \ rename("CopyFile", "MsoCopyFile") \ rename("ReplaceText", "MsoReplaceText") \ rename("ExitWindows", "MsoExitWindows"), \ rename("FindText", "MsoFindText") // 然后使用VS生成MSPPT9.OLB中的Dispatch包装类，当然，你也可以自己用最原始的接口写。 { CApplication oApp; if( !oApp.CreateDispatch( _T("PowerPoint.Application")) ) { AfxMessageBox( _T("无法启动PowerPoint，请确认您的机器上已经正确安装PowerPoint!") ); return; } { CPresentations oPresentations(oApp.get_Presentations()); LPDISPATCH lpDispPresentation = oPresentations.Open( m_strFilePath, TRUE, 0L, FALSE); if( lpDispPresentation == NULL ) AfxMessageBox( _T("打开文件失败!") ); else { CPresentation oPresentation(lpDispPresentation); const LPCTSTR OUTPUT_FILE_FORMAT = _T("png"); const long OUTPUT_IMG_WIDTH = 1024; const long OUTPUT_IMG_HEIGHT = 768; oPresentation.Export( strPath, OUTPUT_FILE_FORMAT, OUTPUT_IMG_WIDTH, OUTPUT_IMG_HEIGHT); oPresentation.Close(); } } oApp.Quit(); }
