Visually remove/disable close button from title bar .NET

Question

I have been asked to remove or disable the close button from our VB .NET 2005 MDI application. There are no native properties on a form that allow you to grey out the close

Answer 1

What jmweb said here is OK as well. The X close button won't go if you cancel the event on form closing. But doing so, you need to release the processes the form needs and then closing the form.

Me.Dispose()
Me.Close()

This worked for me using Menu Strip.
