XL2000: Error Running Macro That Inserts Control into UserForm

In Microsoft Excel 2000, when you run a Microsoft 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:

This behavior occurs when the following conditions are true:

• The control you are using is included in the Microsoft Forms 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)
  					

This behavior occurs because these controls exist in both the Microsoft Excel Object Library, which applies to dialog sheets, and in the Microsoft Forms Object Library, which applies to UserForms.

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 Object Library. This causes a problem when you attempt to insert a control by using the Set statement.

1. Type MsForms. at the beginning of the data type in the Dim statement. For example, change the examples in the "Cause" section to the following:

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

2. Set the variable to the control that you want to add using Visual Basic code.
