The problem is, when you press ENTER again to clear the message box,
your text box eventually gets another "key up" message, and shows
another message box.

Put the code in a KeyPress event handler instead, and this problem
won't occur:

private void txtJobName_KeyPress(object sender,
System.Windows.Forms.KeyPressEventArgs e)
{
if (e.KeyChar == 13) {
MessageBox.Show("xyz");
txtJobName.Focus();
}
}
