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（)
{
cstring strdevicename=m_strdevicename;
lpdispatch pdisp;
lpunknown punk;
clsid clsid;
const int nwordnum=10;
const cstring wordprog[]=
{
"word.application.7 "
, "word.application.8 "
, "word.application.9 "
, "word.application.10 "
, "word.application.11 "
, "word.application.12 "
, "word.application.13 "
, "word.application.14 "
, "word.application.15 "
, "word.application.16 "
};
uses_conversion;
cstring strwordprog;
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;
}
if（::getactiveobject（clsid, null, &punk) == s_ok)//如果word已经打开
{
verify（punk-> queryinterface（iid_idispatch,
（void**) &pdisp) == s_ok);
m_app.attachdispatch（pdisp);
punk-> release（);
m_bwordopen=true;
trace（ " attach complete\n ");
}
else
{
if（!m_app.createdispatch（strwordprog))//创建word对象 这里创建失败
{
trace（ "create failed\n ");
return;
}
m_bwordopen=false;
trace（ " create complete\n ");
}
m_app.setvisible（true);//显示word窗口
lpdispatch pdocuments;
pdocuments=m_app.getdocuments（);
documents documents;
documents.attachdispatch（pdocuments);
lpdispatch pdocument;
variant filename;
filename.vt=vt_bstr;
filename.bstrval=strdevicename.allocsysstring（);
variant confirmconversions, readonly;

//在外层已经处理了，如果文件在存在，那一定是打开的
cfilefind filefinder;
if（filefinder.findfile（strdevicename))
pdocument=documents.open（&filename, &confirmconversions, &readonly,
&addtorecentfiles, &passworddocument, &passwordtemplate,
&revert, &writepassworddocument, &writepasswordtemplate,
&format);
else
pdocument=documents.add（);
m_document.attachdispatch（pdocument);
lpdispatch pselection;
