To set the border style of Windows Forms at design time
In the Properties window, set the FormBorderStyle property to the style you want.
Choosing a border style will control the presence of the Minimize and Maximize boxes on the title bar. To turn their functionality on or off, but leave them present, see the following procedure, "To disable the Minimize and Maximize buttons on Windows Forms."
The border style of a form is set using the FormBorderStyle enumeration. Setting or changing the border style of your form in code is merely a matter of setting the FormBorderStyle property to one of the values of this enumeration.
An example of a form that has a definitive border style is a dialog box, which uses the FixedDialog border style.
