Symptoms

When you attempt to set or change the Visible property of a UserForm, you may receive the following error message:
Compile Error: Function or interface marked as restricted, or the function uses an Automation type not supported in Visual Basic.

Cause

This behavior can occur when you attempt to modify a read-only property. For example, the following sample Microsoft Visual Basic for Applications code generates the error message described in the "Symptoms" section:
Sub HideForm()
   UserForm1.Visible = False ' Generates a Compile error.
End Sub
Sub ShowForm()
   UserForm1.Visible = True  ' Generates a Compile error.
End Sub

To modify the Visible state of a form, use the Hide and Show methods to change the form's Visible property.

NOTE: The following sample code assumes that 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 code hides a UserForm:
Sub HideForm()
   UserForm1.Hide
End Sub
				
The following sample code shows a UserForm:
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
      MsgBox "The form is visible"
      ' Do something when the form is visible.
   End If
   ' Determine whether the form is hidden.
   If UserForm1.Visible = False Then
       MsgBox "The form is hidden"
       ' Do something when the form is hidden.
   End If
End Sub
