Hi there,

Can some plz suggest me a way to show .ppt files on my website that
can't be copied or saved by user using asp.net.

any idea !!!!

thankx
 
If you mean not being copied/saved as *.ppt file, then the only way is not
to post the presentation as *.ppt file. You could convert it to PDF file,
for example.

If you mean not copying the content/image in any format, then you cannot
prevent that, unless you do not shaw it on the net at all.
 
the only way is to supply your own client application that displays the
ppt (the web file should be encrypted). the browser always downloads the
file to the file cache and calls the app to display it.

If that's really the case, tell your boss to put the files on his own
webserver, where he denies access to anyone apart from himself.

I use a login with username and password up front. Then only persons with
appropriate credentials get access to specific files. All sorts of filtering
can be done that way. I have a SQL table containing userID's and like 10
different access items per user.

So it means that the PPT files are actually not just stored on the
server, but have to be displayed to someone, do I understand correctly?
In that case, in order to be displayed, they need to be downloaded first.

In that case, Bruce Barker's suggestion is the only possible way.

The point which *you* don't seem to understand is that everything which is
displayed in a browser is downloaded to the client machine... That includes
the HTML, JavaScript, binaries etc... If you don't want a file to be
downloaded to the client machine, don't show it in a browser - it really is
as simple as that...

This question comes up fairly regularly, most often in the case of people
who are selling images e.g. photographs via their website - people need to
see the photos so that they know what they're buying, but if they can just
right-click the image and do Save As, they will have no incentive to buy...

Another interesting statement you make is "My boss wants..." - often bosses
can benefit from a bit of expectation management... I suggest you go through
this thread with your boss and try to explain why his / her requirements are
unrealistic...

Finally, what are you (or your boss) *actually* worried about here...? What
will happen if one of your PowerPoint presentations is downloaded...?

From what I heard, the glaciers and the north pole will melt, and the
level of the sea will rise by at least a meter. Oh wait, I believe I am
thinking of another catastrophe...

A PDF version could be viewed by anyone, and the full PPT may be downloaded
by users with correct credentials. But even with a PDF view it will be hard
to prevent copying, at least the printscreen will be there.
