Hi,

I have recently been coding with VC++. I use an automation client to add an
equation to a word document hereunder:
     ......
     _Application app;
     app.CreateDispatch("Word.Application");
     app.SetVisible(TRUE);
     _variant_t vtNULL((long)DISP_E_PARAMNOTFOUND,
                                VT_ERROR);
     Documents docs(app.GetDocuments());
     _Document _doc(docs.Add(&vtNULL,
                                            &vtNULL,
                                            &vtNULL,
                                            &vtNULL));
     InlineShapes shapes(_doc.GetInlineShapes());
     _variant_t vtCls("Equation.3");
     LPDISPATCH lpDisp =
           shapes.AddOLEObject(&vtCls,
             &vtNULL,
             &vtNULL,
             &vtNULL,
             &vtNULL,
             &vtNULL,
             &vtNULL,
             &vtNULL);

          ......
the equation is inserted successfully and the inserting function returns a
pointer of type LPDISPATCH to the OLE object.

My question is, how can i add more content to the equation with this pointer?
Is there a type lib for "Microsoft Equation.3"?

Thanks in advance
