Hello,
I need to develop a web site for a learning centre in asp.net 2.0.
They want to deliver part of their courses on-line. The customer will have a
username and password to access a reserved area.
In this area, they need to show some powerpoint files resuming the lessons.
The end users can or cannot have powerpoint installed on their computer,
so I though that a ppt viewer is needed.

There are a couple of check in "Folder Option" -> "File Types" that
can change the behaviour of our web application:

"Browse in same window": if it's not checked, the ppt is loaded outside a
web page
"Confirm open after download": if it's checked, the system ask if you want
to open the file or download it into your system.

Is there a way to bypass the user configuration on the machine, in order to
be sure that he will always open the file in the browser window as we expect?

Do I need to develop a custom control for that?

Any hints will be appreciated.

Thanks!
