Hi all,

I've a vb application that uses the crystal report to display some reports.
User have the option to export the report to pdf format. My question is that
the report that the users export out, I do not want to them to be able to do
any changes (i.e. convert to word doc, do the changes and convert back to
pdf).

I understand that the crystal report is not able to accomplish this. Can
anyone please advice? I tried looking at the Adobe Acrobat SDK, but I think
that it might take me a least a month to figure it out :-(

Thanks,
Simon
 
Hi Spam Catcher,

Thanks for your reply. Will this able to prevent user from able to edit the
pdf document? Also, I see the code is in C#, will I be able to use in
vb.net?

C# and VB.NET are both languages of the .NET platform. So yes, while the
syntax is different, the code is compatible.

I believe once you signed a PDF, the user cannot edit the file. If they do,
they'll render the signature invalid.
