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.



WORKAROUND
Microsoft provides programming examples for illustration only, without warranty either expressed or implied. This includes, but is not limited to, the implied warranties of merchantability or fitness for a particular purpose. This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements. 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.



MORE INFORMATION
An OLE object type is a type of object exposed by a program through Automation. Some of the types of objects that Microsoft Excel exposes through Automation include Application, File, and Sheet. In the following example, the variable MySheet is declared as Sheet type: Dim MySheet as Sheet
