I totally didn't understand the part about not making use of an EventHandler

public Form1()

    // Create a TextBox control.
    TextBox tb = new TextBox();
    this.Controls.Add(tb);
    tb.KeyPress += new KeyPressEventHandler(keypressed);
}

private void keypressed(Object o, KeyPressEventArgs e)
{
    // The keypressed method uses the KeyChar property to check
    // whether the ENTER key is pressed.

    // If the ENTER key is pressed, the Handled property is set to true,
    // to indicate the event is handled.
    if (e.KeyChar == (char)Keys.Return)

The only programmers that are better C# programmers, are those who look like this ->

if (e.Keycode == Keys.Enter)
    e.Handled = true;
