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



RESOLUTION
Microsoft provides programming examples for illustration only, without warranty either expressed or implied. This includes, but is not limited to, the implied warranties of merchantability or fitness for a particular purpose. This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements. 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



STATUS
This behavior is by design. Microsoft welcomes suggestions or comments about changes in functionality and product design.
