I try to write a simple MFC - Word Automation to save for every 1 minute. I follow this article : http://www.codeproject.com/KB/office/MSOfficeAuto.aspx

And this is what Im trying to implement , I'm new to COM so I think there's problem here: my VBA is generated by Word 2010:

ActiveDocument.SaveAs2 FileName:="1.docx", FileFormat:=wdFormatXMLDocument _
    , LockComments:=False, Password:="", AddToRecentFiles:=True, _
    WritePassword:="", ReadOnlyRecommended:=False, EmbedTrueTypeFonts:=False, _
     SaveNativePictureFormat:=False, SaveFormsData:=False, SaveAsAOCELetter:= _
    False, CompatibilityMode:=14

And my code to implement VBA code above :

{
    COleVariant varName(L"b.docx");
    COleVariant varFormat(L"wdFormatXMLDocument");
    COleVariant varLockCmt((BYTE)0);
    COleVariant varPass(L"");
    COleVariant varReadOnly((BYTE)0);
    COleVariant varEmbedFont((BYTE)0);
    COleVariant varSaveNativePicFormat((BYTE)0);
    COleVariant varForms((BYTE)0);
    COleVariant varAOCE((BYTE)0);
    VARIANT x;
    x.vt = VT_I4;
    x.lVal = 14;
    COleVariant varCompability(&x);;

    VARIANT result;
    VariantInit(&result);
    _hr=OLEMethod(  DISPATCH_METHOD, &result, pDocApp, L"SaveAs2",10,
                    varName.Detach(),varFormat.Detach(),varLockCmt.Detach(),varPass.Detach(),varReadOnly.Detach(),
                    varEmbedFont.Detach(),varSaveNativePicFormat.Detach(),varForms.Detach(),varAOCE.Detach(),varCompability.Detach()
                 );
}

I get no error from this one, but it doesn't work.
