>Gentlemen, I need help.
>
>I have a html or .chm file for my help file.
>In my computer it works great. In a few of my customers, it works Okay.
>However, in most of my customers when they click on the menu help file, nothing happens. They can't get to the .chm help files.
>Some of them do have windows XP so I'm not sure what the problem is.
>
>My code:
>

>xdirect = SYS(5)+SYS(2003)
>DO case
>     CASE Which = 1
>          ShellExec(xdirect+"\HELPFILE.PDF")
>     CASE Which = 2
>          ShellExec(xdirect+"\SCGHELP.CHM")
>     CASE Which = 3
>          do oldprtinstr
>     OTHERWISE
>          DO oldprtinstr
>ENDCASE
>

>As you can see, I have added a choice of the PDF file which always seems to work fine. It is a collection of the html file. It does the job but the html help file would be much nicer and easier to use by the customer.
>
>Because the .chm file always works in my computer, I can't figure out what is wrong.
>
>What am I doing wrong ?
>Is there another code besides ShellExec to use ?
>
>Thanks,
>Loren
