How to make textbox accept just numbers(from 0 - 9)?

see http://www.eworldui.net/CustomControls/NumericBox.aspx

Imports Microsoft.VisualBasic
       
        Dim MyInt As Integer
        If IsNumeric(txtbox.Text) Then MyInt = txtbox.Text
        If MyInt >= 0 And MyInt <= 9 Then
            'do something
        Else
            'err msg
        End If

Actually I want to use a validator control, like comparevalidator.

i think the required field validator allows you to put in a min and max value....

I do not want range validation I just want to accept numbers, no aphabatic characters.

RainMan82... you think bad :)
