我获得我机器上WORD的版本为Word.Application.8 
我在用CreateDispatch("Word.Application.8") 但创建失败 
在CreateDispatch函数中的AfxGetClassIDFromString()函数 返回为0
偶谁能解释下吗?
谢谢叻.

初始化函数代码如下:

void COutputWord::Init()

, "Word.Application.12"
, "Word.Application.13"
, "Word.Application.14"
, "Word.Application.15"
, "Word.Application.16"
};

for(int nWordID=0; nWordID < nWordNum; ++nWordID)
{
::CLSIDFromProgID(A2OLE(WordProg[nWordID]), &clsid); //从注册表中获得信息 
if(clsid != GUID_NULL)
{
strWordProg=WordProg[nWordID];
break;
}
}

if(clsid == GUID_NULL)
{
return;
}

{

} 
else
