In visual basic 2005 express edition what is a code for making it so that only certain characters can be allowed in a text box?

Hi, You can write code in keypressed event for any control and validate whether only allowed Characters are keyed in. Private sub Txt_MyTexbox.KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs)
Select Case LCase(e.KeyChar)
Case "A"
Case "B"
Case "0"
Case "2"
Case "9"
End Select
End Sub

Like this you can check for any key and validate.
Hope this helps
