Easier is to just manage closing of the form with the queryclose event:

Private Sub UserForm_QueryClose(Cancel As Integer, CloseMode As Integer)
'Prevent user from closing with the Close box in the title bar.
If CloseMode < 1 Then Cancel = 1
UserForm1.Caption = "Use the close button"
End Sub


If you still want to remove the X button, then you need to use the Windows
API.
