Keyboard Input in Visual C

1. Select the Form and go to its Properties
2. Change the KeyPreview property to True
3. Add the following line of code to the public Form1() section:

this.KeyDown += new KeyEventHandler(Form1_KeyDown);

so it should look something like this:

public Form1()
{
    InitializeComponent();
    this.KeyDown += new KeyEventHandler(Form1_KeyDown);
}

1. Add the following section of code

<sounrce lang="csharp">

       private void Form1_KeyDown(object sender, System.Windows.Forms.KeyEventArgs e)
       {
           switch (e.KeyCode)
           {
               case Keys.Left:
                   //add code that you want to run when the Left key is hit
                   break;

               case Keys.Right:
                   //add code that you want to run when the Right key is hit
                   break;

               case Keys.Up:
                   //add code that you want to run when the Up key is hit
                   break;

               case Keys.Down:
                   //add code that you want to run when the Down key is hit
                   break;

               default:
                   return;
           }
       }
