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
