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
