TITLE   :PRB: Type Mismatch Using OLE Automation to Word 97
PRODUCT :Microsoft FoxPro
PROD/VER:3.0 3.0b 5.00 5.0a 8.0 97
OPER/SYS:
KEYWORDS:kberrmsg kbvfp kbVS97sp1fix kbVS97sp2fix

======================================================================
-------------------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Visual FoxPro for Windows, versions 3.0, 3.0b, 5.0, 5.0a, on platform(s):
    - the operating system: Microsoft Windows NT 
    - the operating system: Microsoft Windows 95 
-------------------------------------------------------------------------------

SYMPTOMS
========

When using OLE automation to interact with Microsoft Word 97 and the Visual
Basic for Applications language, certain commands return the following error to
Visual FoxPro:

   OLE error code 0x80020005: Type Mismatch.

CAUSE
=====

This problem is caused by a problem in the way Word 97 returns mismatched errors
from the OLE DISPATCH methods.

RESOLUTION
==========

There are two ways to solve the error:

1. Use the equivalent Word.Basic methods with the WordBasic property within the
   Word.Application object. See the example below.

2. Use only the Word.Basic object.

STATUS
======

Microsoft has confirmed this to be a bug in the Microsoft products listed at the
beginning of this article. This bug has been fixed in Visual Studio 97 Service
Pack 2.

For more information on the Visual Studio 97 Service Pack 2, please see the
following article in the Microsoft Knowledge Base:

MORE INFORMATION
================

Starting with Word 97, OLE automation from other applications, such as Visual
FoxPro, can access the Word 97 Visual Basic for Applications (VBA) objects by
issuing the CreateObject("Word.Application") command in Visual FoxPro. However,
some of the methods used in Word 97 VBA return errors back to the client
application. When an error is returned to the client application, like Visual
FoxPro, it may be necessary to use older Word Basic statements and functions in
conjunction with the newer Word.Application methods and properties. The purpose
of the WordBasic property is to return an Automation object (Word.Basic) that
includes methods for all the WordBasic statements and functions available in
Word version 6.0 and Word for Windows 95.

To accomplish this while there is reference created to the Word.Application
object, preface the Word.Basic statement or function with the WordBasic
property, then follow with the desired Word.Basic statement or function. See the
code example below.

The ActiveDocument.SaveAs method is not the only method that returns the above
error, it is the only one covered in this article. Again if the error is
returned, try using one of the covered workarounds.

Steps to Reproduce Behavior
---------------------------

The following code can be entered in the Command window, in a program, or in a
method on a form:

   

      oWord=CreateObject("Word.Application")
      oWord.Documents.Add
      oWord.Selection.InsertAfter("This is a test")
      oWord.Visible=.T.
      *The line below will error. But this is a valid Word VBA command
      oWord.ActiveDocument.SaveAs("Mydoc")
      oWord.Quit

To avoid the above error, revert back to the WordBasic equivalent command.
Replace the ActiveDocument.SaveAs above with the following line:

   

      oWord.WordBasic.FileSaveAs("Mydoc")    && Will save document

Another option is to use only the Word.Basic object model. Enter the following
code in the Command window, in a program, or in a method on a form:

   

      oWord=CreateObject("Word.Basic")
      oWord.FileNew
      oWord.Insert("This is a test")
      oWord.AppShow
      oWord.FileSaveAs("Mydoc")
      oWord.FileQuit
