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

The Visible property is designed to let you check the Visible state of a specific
form, but not modify it. To modify the Visible state of a form, use the Hide and
Show methods to change the form's Visible property.

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

The following sample Visual Basic 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
           ' 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
