XL98: Run-time Error Using For Each Loop with OLE Object Type (192279)

SYMPTOMS

If you use the For Each...Next statement in a Visual Basic for Applications macro, 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 the following error message when you run the macro procedure:

Run-time error '13':
Type mismatch

CAUSE

This problem 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

you will receive the error message described in the "Symptoms" section of this article.

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 an error message 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

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:
