numeric only textbox

i thought .net had a property to do this but i can't find it. what is the .net way to do it?

with keypress event

Code:

---

Private Sub OnKeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs)

  e.Handled = (Not Char.IsControl(e.KeyChar)) AndAlso _
    (Not Char.IsNumber(e.KeyChar)) AndAlso _
    (Not (Char.IsPunctuation(e.KeyChar) And _
    (((e.KeyChar = ".") And
    (Text.IndexOf(".") = -1)) Or _
    ((e.KeyChar = "-") And (SelectionStart = 0)))))

End Sub

---

that allows decimals and negative numbers also

also take not that if it is something you may use more often, you can create a class that inherits TextBox and change Private to Protected Overrides for the event. Now you have a reusable numeric only textbox class that retains all the orginal textbox functionality

Isnt inheritance awesome?

.handled ok thanks bro
