Hi Larrson, Truncated Hashing. See http://www.codeproject.com/useritems/InstallationID.asp. In a nutshell, grab the entire hash from the obhect, then extract bytes[0 - 4].
As for the integer conversion, look the the Integer class ctors. Jeff On 11/9/07, Larrson <[EMAIL PROTECTED]> wrote: > > Hi all, > > I've got lost a bit.
