" Simple file shares (dare I say even "sharepoint"?) make rich client
distribution fall-off-a-log easy and secure. "
The basic principle is:
- create a "startup" application that checks a "file share" for updates
and downloads them (all kinds of ways to do this - I myself never relied
on "file timestamps")
- the "file share" can be anything: FTP site, even using HTTP, and
Sharepoint can be used because you can access files via http links there
(although it is a MS product so gotta be careful :) )
- the main app also checks the file share for updates to the "startup"
app and downloads as necessary (can't overwrite an .exe in use... well,
not easily anyway)
From there you can add all kinds of security checking of the .exe
content, etc, to ensure someone did not compromise the file share. And
in one very paranoid case, we had a "secret sever" monitoring the
"visible/published" file share, comparing it to it's own version - and
if something was out of sync, log it, and copy over it from the "secret
server". But really, if someone hacked the enterprise network deep
enough to copy files around, figuring out where and what .exe to
substitute is probably not even a thought.
Using this approach I also added a little logic inside the .exe to
detect the operating system version and existence of other resources
(one program actually used MS Powerpoint via Automation - to my
chagrin... but that's what they wanted). I believe at one time I had an
application running on desktops with Windows 98, XP, Vista (which was a
pain in the a....), 7, all at the same time.
Compared to browser incompatibilities, bizarre rendering that experts
could not figure out, security snafus, and did I mention pathetic
performance.... desktop application distribution was a dream.
