Universal function to check for entered digits only

[John Smith]

Hello,

I'd like to create a function that will allow users to only enter
numbers in some textboxes. I'm trying to create only one function and
call it for each textbox.keypres s event instead of creating one for
each textbox.

This is what I have (and works):

Private Function DigitsOnly(ByVa l sender As System.Object, ByVal e As
System.Windows. Forms.KeyPressE ventArgs) Handles _
txtOrderNumber. KeyPress

' set the Order Number textbox to accept only digits, the
Backspace, the Tab, or the Enter key.
If Not (Char.IsNumber( e.KeyChar) OrElse AscW(e.KeyChar) = 8
OrElse AscW(e.KeyChar) = 9 OrElse AscW(e.KeyChar) = 13) Then
e.Handled = True
End If

End Function

However, how do I create it without stating the textbox handler
(Handles txtOrderNumber. KeyPress) so I can call it from any textbox,
pass the textbox name as the object to be handled and then execute it?

For example,

' call the DigitsOnly function
DigitsOnly(txtM yOtherTextBox.n ame)
Right now if I try to create a variable for this and use it I get an
error stating "Handles clause requires a WithEvents variable).

Thanks for all your help guys (and gals)!

How about creating a custom order number textbox?
