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();
}
