example code

<input name="text" value="" onkeypress="inputValidation()">
<script type="text/vbscript">
Sub inputValidation
With window.event
msgbox .keyCode
End With
End Sub
</script>

when i press key "0" then msgbox = 48
when i press key "0" on the internet part of keyboard, then msgbox = 48

----------------------------------------------------------------
<input name="text" value="" onkeydown="inputValidation()">
<script type="text/vbscript">
Sub inputValidation
With window.event
msgbox .keyCode
End With
End Sub
</script>

when i press key "0" then msgbox = 48
when i press key "0" on the internet part of keyboard, then msgbox = 96

why it is ? , why when i use onkeydown or onkeypress i get different keyCodes ?

Not sure why it is doing this but have you tried seeing what onkeyup returns??

I suspect it is something about how the "internet" part of the keyboard is setup up. What do you mean my Internet part anyway?
