You're not being naïve at all. Maybe I did not express myself correctly. The way my system works is this:
Whenever a user, previously authorized by his/her password to examine the documents, wants to read a doc, xls, pdf file, it is the program that pulls the requested file and shows it in the screen for the user to read. I then use the _environment.vcx that ships with VFP to shell execute the document. It can be read, modified, saved, printed, emailed, etc. This are precisely the possibilities I want to prevent the users to have. I just want them to read, and only read the Word, Excel or PDF document. No modifying, printing, saving, emailing...... Of course if they use their cell phone to take a picture of the screen, well, then I'm screwed, but other than that..... Am I clear now? Rafael El 01/06/2011 15:30, Joel N.
