有关wordoperation打开某一文件的问题

[nudt_zdk]

我用word Application类对word文件进行处理

想打开一个word文件 但发现open函数有十二个参数设置

现在不知道如何设置这些参数 请高手指教 谢谢

LPDISPATCH Open(VARIANT* FileName,
VARIANT* ConfirmConversions,
VARIANT* ReadOnly,
VARIANT* AddToRecentFiles,
VARIANT* PasswordDocument,
VARIANT* PasswordTemplate,
VARIANT* Revert,
VARIANT* WritePasswordDocument,
VARIANT* WritePasswordTemplate,
VARIANT* Format,
VARIANT* Encoding,
VARIANT* Visible);

我有一个另存为的函数的参数设置例子

_Document doc=app.GetActiveDocument();//得到ActiveDocument
CComVariant FileName(_T("c:\\Hello.doc")); //文件名
CComVariant FileFormat(0);
CComVariant LockComments(false),Password(_T(""));
CComVariant AddToRecentFiles(true),WritePassword(_T(""));
CComVariant ReadOnlyRecommended(false),EmbedTrueTypeFonts(false);
CComVariant SaveNativePictureFormat(false),SaveFormsData(false);
CComVariant SaveAsAOCELetter(false);


doc.SaveAs(&FileName,&FileFormat,&LockComments,&Password,
&AddToRecentFiles,&WritePassword,&ReadOnlyRecommended,
&EmbedTrueTypeFonts,&SaveNativePictureFormat,&SaveFormsData,
&SaveAsAOCELetter);
