Property ControlBox=false Use event FormClosing and set e.Cancel=true.

You can set

Form.ControlBox=false;

but this also removes the Min, Max, and system menu from the form as well. To grey out the Close box, override the CreateParms getter:

    protected override CreateParams CreateParams
        {
        get
            {
            CreateParams parms = base.CreateParams;
            parms.ClassStyle |= 0x200;  // CS\_NOCLOSE
            return parms;
            }
        }

you can do it like this

this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;

but, you need to write methods such as 'MovingForm'or 'ResizeForm' or something else by yourself.
