crystal report problem

[Agnes]

I write the invoice by using crystal report in vb.net .
I can export it into *.pdf very well, However, it can also export to word,
excel also.
we are afraid that the user export the invoice into excel format and then
amend it by himself.
Can I allow the crystal report export to *.pdf only ?? or make their excel
or word file (read only) ???
Thanks a lot

Re: crystal report problem

Agnes,

Even PDF documents can be modified, so I don't think that would be a
solution. Why is it a problem that the user can modify the invoice? I'm
assuming that the report is simply an electronic copy of the invoice details
stored in your system. If that's so, it shouldn't matter if the invoice is
modified. I probably don't understand your problem, so please enlighten me.
:-)

Re: crystal report problem

The invoice 'print out copy' must be amend by the user since my client
receive the petty cash thr the invoice, He afraid that some bad guy amend
the amount of the invoice (e.g from 1000 to 1100), He will receive the cash
1100, HOwevever, there is only $1000 in the computer system. That bad guy
just give back $1000 to a/c system .

Re: crystal report problem

Hmm, yes I do see your problem. Maing a file read-only in the normal sense,
by setting a file system attribute isn't a valid option, as that's easily
bypassed. I'm no expert on this matter, but would Windows Rights Management
Services be something you can use for this,
http://www.microsoft.com/windowsserv.../default.mspx?

I obviously don't know your system well enough, but would it be possible to
send a copy of the original document automatically, or print out a copy with
some sort of watermarking or similar, for the user to deliver with the
amended copy? Just a thought.
