Re: Get ASCII value for character when higher than 127

Thanks, this helped me further a bit. But I'm still not able to get
the correct int value for the special characters. For example, when I
reset a users password to the following:

??Abc1????p$%^

The int values that are written to my textfile for the password file
are:

0-61-0-87-0065-0098-0099-0049-0-58--110-0-61-0-85-0112-

And this should be:

0130-0065-0098-0099-0049-0159-0137-0112-0036-0037-0094-

Any idea what it is I'm still doing wrong? My code now looks like
below.

Thanks again,
Sandra
