XL: GP Fault/Error Using For Each Statement with OLE Object Type

ID: Q119570

The information in this article applies to:

Microsoft Excel for Windows, versions 5.0, 5.0c
Microsoft Excel for Windows 95, versions 7.0, 7.0a
Microsoft Excel 97 for Windows
Microsoft Excel for the Macintosh, versions 5.0, 5.0a

SYMPTOMS

If you use the For Each...Next statement in a Visual Basic module in Microsoft Excel, and you declare the variable used to iterate through the elements of the collection as an OLE object type, such as MenuItem, you may receive one of the following error messages when you run the macro.

Microsoft Excel 97 for Windows and Microsoft Excel for the Macintosh, version 5.0

Run-time error '13':
Type mismatch

In Microsoft Excel for Windows, versions 5.0 and 7.0

General Protection (GP) fault in module VBA.DLL

When you receive this error message, the program stops responding (hangs).

CAUSE

This behavior occurs only if an error is encountered while the objects are being retrieved from the collection This problem may occur with object types that include MenuItem, Sheet, and DrawingObject.

For example, if you run the following procedure


   Sub Show_Menu_Items()
       Dim m as MenuItem
       For Each m In Activemenubar.Menus("Tools").MenuItems
           MsgBox m.Caption
       Next
   End Sub

and a command on the Tools menu contains a submenu, you will receive the error message described in the "Symptoms" section of this article.

When you click End, Debug or Goto in the error message dialog box, you receive a GP fault in module VBA.DLL at 0023:2723.

To avoid receiving a GP fault when you use the For Each...Next statement in a Visual Basic module, declare the variable used to iterate through the elements of the collection as Variant type, or Object type instead of as an OLE object type as in the following example:


   Sub Show_Menu_Items()
       Dim m as Object
       For Each m In ActiveMenuBar.Menus("Tools").MenuItems
           MsgBox m.Caption
       Next
   End Sub

Note that in Microsoft Excel 97, and Microsoft Excel for the Macintosh, version 5.0, you still receive the "type mismatch" error message, but you do not receive the GP fault. To avoid receiving this error message, use the workaround in this article.

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article.
