OFF98: Compile Error Using the Visible Property of UserForms

• Microsoft Word 98 Macintosh Edition
• Microsoft Excel 98 Macintosh Edition
• Microsoft PowerPoint 98 Macintosh Edition

SYMPTOMS

When you attempt to set or change the Visible property of a UserForm, you receive the following error message:

   Compile error:

   Wrong number of arguments or invalid property assignment.

CAUSE

This error occurs when you attempt to modify a read-only property. For example, the following sample Microsoft Visual Basic for Applications code generates the error:

   Sub HideForm()
      UserForm1.Visible = False ' Generates a Compile error.
   End Sub

   Sub ShowForm()
      UserForm1.Visible = True  ' Generates a Compile error.
   End Sub

NOTE: The following code samples assume your form is named UserForm1. Replace UserForm1 with the name of your form or a reference to your form.

How to Use the Show and Hide Methods

The following sample Visual Basic code hides a UserForm:

   Sub HideForm()
      UserForm1.Hide
   End Sub

   Sub ShowForm()
      UserForm1.Show
   End Sub

How to Use the Visible Property

The following sample Visual Basic code checks the Visible property of a form:

   Sub CheckFormState()

      ' Determine whether the form is visible.
      If UserForm1.Visible = True Then
         ' Do something when the form is visible.
      End If

      ' Determine whether the form is hidden.
      If UserForm1.Visible = False Then
          ' Do something when the form is hidden.
      End If

   End Sub
