Defining the Border Style

The previous examples are both simple, fixed-size forms that have no minimize or restore button. The border style of the form object controls how a form is shown and if it can be resized.

Listing 3.1.4 shows a very simple Windows Forms application with a sizable client area.

Listing 3.1.4 resize.cs: A Simple Resizable Windows Forms Application

using System;
using System.Drawing;
using System.ComponentModel;
using System.WinForms;


public class SizeApp : System.WinForms.Form
{

  public   SizeApp()
  {
    this.Text = "SizeApp";
    this.MaximizeBox = true;
    this.BorderStyle = FormBorderStyle.Sizable;
  }

  static void Main()
  {
    Application.Run(new SizeApp());
  }


}

Building and running this application will result in a resizable application that can also be minimized to the taskbar and restored in the normal way.
