Hi,
Thanks I saw the code and made it to suit my requirement
It working fine with windows but gives error on Lunux hostinf asp webserver

Microsoft VBScript runtime error '800a0005'
Invalid procedure call or argument: 'asc'
func.asp, line 39

if u have used ...please tell me what could be the reason
error in in this function

Function lngConvert2(strTemp)
lngConvert2 = clng(asc(right(strTemp, 1)) + ((asc(left(strTemp, 1)) * 256)))
End function

Thanks

Try to not use CLng or CStr, i have some problems with that...
Try to use just Int or Str, but in your example u dont need to convert an number(Asc() return an number) to an number.

Function lngConvert2(strTemp)
    lngConvert2 = Asc(Right(strTemp, 1)) + Asc(Left(strTemp, 1) * 256

Hope this works... ________
