Default Restricting the # of digits after a decimal in a K

Greetings Everyone!
 I have a simple question in what is the correct way to restrict the number of digits after the decimal point? As shown with my code below I was able to create a textbox in which when a user enters value such as 1232.23232 is possible...however I want to make the textbox more user friendly I restricting digits after the decimal to 2. So it would look more like this 1232.23. Thank you for all your time..any guidance and help would be greatly appreciated.

Public Class Form1

Private Sub txtPayment_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtPayment.KeyPress
Const x As Integer = 2
If e.KeyChar = Chr(8) Then Exit Sub

Select Case e.KeyChar
Case "0" To "9"
'ok
Case "."
If (InStr(txtPayment.Text, ".")) <> x Then
e.Handled = True
Beep()
End If
Case Else
e.Handled = True
Beep()
End Select


End Sub
End Class

hi there...
idea (because there is many many ways to do this):

count the number of digits after the period and if you have two cancel the input...

by the way.. if you are using .Net, why are you using instr???
