XL97: Error Running Macro That Inserts Control into UserForm

• Microsoft Excel 97 for Windows

SYMPTOMS

In Microsoft Excel 97, when you run a Visual Basic for Applications macro in which you dimension a variable as a UserForm control, such as a check box, a list box, a scroll bar, or an option button, you may receive the following error message:

   Run-time error '13':
   Type mismatch

CAUSE

This behavior occurs when the following conditions are true:

• The control you are using is included in the Microsoft Forms 2.0 Object Library.

  For example, the line of code that dimensions the variable resembles any of the following examples:

        Dim X As CheckBox
        Dim Y As Label
        Dim Z As ListBox
        Dim A As OptionButton
        Dim B As ScrollBar
        Dim C As TextBox
  

      -and-
  

• You attempt to add a control to a UserForm using a line of code similar to the following example:

        Set X = UserForm1.Controls.Add("Forms.Checkbox.1", "Name", True)
  

Unless you add "MsForms." to the beginning of the data type in the Dim statement, Microsoft Excel assumes that you want to use the Microsoft Excel object type, not the type in the Microsoft Forms 2.0 Object Library. This causes a problem when you attempt to insert a control by using the Set statement.
