Inserted OLE Object in my own control fails to display equations RRS feed

  • Question

  • My team made a control used to edit text and picture etc. We added an "Insert OLE Object" function used to insert files like word and excel. The sudo-code is: 

    COleInsertDialog dlg;

    COleClientItem *pItem = NULL;

    ...

     select files

           ... 

      // Initialize the item from the dialog data.

    if (!dlg.CreateItem(pItem))

    {

    AfxThrowMemoryException();  // any exception will do

    return ;

            } 

            .....

            Display the OLE in the View

            .....

      

           The codes work in most cases, but when I try to insert a Word file containing math equations, the math equations can't be displayed correctly and a lot of question marks are  displayed instead.
