OnGotFocus Problem

I am deriving a class from TextBox to implement a NumericBox. I am
overriding OnGotFocus and OnLostFocus methods but On GotFocus is causing
problems. Actually the commented lines are causing problems. These throw
Win32 exception that windows was unable to create handle. I dunno wats
wrong. Plz help

protected override void OnGotFocus(EventArgs e)
{
//this.TextAlign=HorizontalAlignment.Left;
//this.SelectionStart=base.Text.Length;
base.OnGotFocus(e);
}

protected override void OnLostFocus(EventArgs e)
{
this.TextAlign=HorizontalAlignment.Right;
base.OnLostFocus(e);
}

causing problem. Any Clues ???
