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

When you press the X box on the form. The Form1_Closing is done first, then the Form1_Closed is done.

The e.Cancel = True in the Form1_Closing - prevents Form1_Closed from being called therefore, leaving your form still active.
