My KeyDown / KeyUp / KeyPress events are not firing; I can't figure out what
I'm doing wrong.  The code I'm using is basically straight from the manual.

"this" refers to my Windows.Forms.Form object.

[CODE]
this.KeyDown += new
System.Windows.Forms.KeyEventHandler(this.MainForm_KeyDown);
this.KeyPress += new
System.Windows.Forms.KeyPressEventHandler(this.MainForm_KeyPress);
this.KeyUp += new System.Windows.Forms.KeyEventHandler(this.MainForm_KeyUp);
[/CODE]

And for implementations I simply have:

[CODE]
private void MainForm_KeyDown(object sender, KeyEventArgs e)
{
  MessageBox.Show("KeyDown Event!");
  statusBar.Text = e.KeyCode.ToString();
}
private void MainForm_KeyUp(object sender, KeyEventArgs e)
{
  MessageBox.Show("KeyUp Event!");
  statusBar.Text = e.KeyCode.ToString();
}
private void MainForm_KeyPress(object sender, KeyPressEventArgs e)
{
  MessageBox.Show("KeyPress Event!");
  statusBar.Text = e.KeyChar.ToString();
}
[/CODE]

The message boxes are not coming up and the status bar is not changing when
I hit keys.  What am I doing wrong?
