vb.net 2003 win form minimize & maximize enabled close disabled

[woodsprite]

Hello all,

I would like to disable use of the windows form ControlBox "X" or close button with out losing the minimize or maximize buttons. Setting the ControlBox = false removes all three options.

I've tried trapping in the Form.Closing event and it ignores all attempts to abort the cancel and closes the form anyway.

If anyone has any suggestions on how I can either disable the "X" or close button of the form ControlBox or prevent the form from closing in the Form.Closing event I would greatly appreciate it.

This site explains how to do something close enough to what I wanted

Unfortunately when you maximize the form the "X" becomes enabled again, to fix this you have to set the MaximizeBox property for the form to false.

If anyone finds anything better, please let me know. Thank you.

overide the Read Only Property CreateParams

in VB

    Protected Overrides ReadOnly Property CreateParams() As CreateParams
        Get
            Dim CS_NOCLOSE As Integer = Int32.Parse("200", Globalization.NumberStyles.HexNumber)
            Dim cp As CreateParams = MyBase.CreateParams
            cp.ClassStyle = CS_NOCLOSE
            Return cp
        End Get
    End Property

in C#

        protected override CreateParams CreateParams
        {
            get
            {
                const int CS_NOCLOSE = 0x200;
                CreateParams cp = base.CreateParams;
                cp.ClassStyle |= CS_NOCLOSE;
                return cp;
            }
        }
