  不清楚你说的该如何使用

  我现在的做法 

  对于word文档

  hr = CLSIDFromProgID(L"Word.Application", &clsid); //通过ProgID取得CLSID

  hr = GetActiveObject(clsid, NULL, &pUnk); //查找是否有WORD程序在运行

  hr = pUnk->QueryInterface(IID_IDispatch, (LPVOID *)&app);

   

  对于ppt文档

  hr = CLSIDFromProgID(L"PowerPoint.Application", &clsid);//通过ProgID取得CLSID

  hr = GetActiveObject(clsid, NULL, &pUnk);//查找是否有WORD程序在运行

  hr = pUnk->QueryInterface(IID_IDispatch, (LPVOID *)&app);

   

  我现在做的话，只能先用word来检测一遍，再用ppt来检测一边。如果L"Word.Application"能换成L"office.Application",取出后再通过Application.name来判断那就方便多了。
