zero footprint

How would you develop a zero footprint application, is the smart
client application a zero footprint application?
Thanks.

I'd first ask you to define "zero footprint application". What's that? The
only applications that consume no resources are the applications that are
not running at all.

Do you mean "web application"? Or perhaps "one-click installation"? Or
perhaps "application that requires no installation"? Or "application that
doesn't store any files"? Or...

sorry for the vague question. I think 'zero footprint' means client
box should not have any content of your application or the application
has to run in 'low' security, I am not sure??? I would like to know in
the following situations. Lets say if I had to create a 'smart client'
application, which is installed through 'click once' and it consumes
some files that are not in its data folder to do some 'file upload'. I
know you could create click once application to work as connected mode
only and disconnected mode also. If you were to run the click once app
in disconnected mode then it is not zero foot print. But if this
application would be a connected mode only, will the app be a 'zero
footprint' application, meaning no app or data is kept on client box?
What I know about connected mode also the application has to be
installed and I think it will get installed in a temp folder or some
(I not sure) and the content is not kept in definite place like other
offline programs.
Second part, if I have a web application what makes a zero footprint,
I thought by default, web apps are zero foot print apps. Does it mean,
you are not supposed to have any activex components or something like
it?

Well, first define zero footprint (do you mean zero-touch?).

A typical smart-client, however, could still be deployed in a number
of ways: ClickOnce, zero-touch, an installer or xcopy.
All of these except zero-touch will require space on the local disk.
Zero-touch typically requires first configuring the local computer to
silently trust the source (perhaps via caspol) - which is often quite
problematic in itself, and even *then* it might cache locally first,
again taking disk space.

Web-based (browser) apps might be described as zero footprint;
potentially (if not encrypted) it might take cache space in the temp
internet area, but that isn't long-term storage.

meaning no app or data is kept on client box?
ClickOnce pretty-much always downloads itself and runs locally (even
in online mode) - it just hides itself away in a system folder in the
user's profile. Strictly speaking there are some things you can do in
the manifest to delay-load parts of it, but mot times it isn't worth
the pain. If you use a settings file, then that will also save locally
(unless you customise it, perhaps using the new Orcas features). Any
other data is up to you to store, so only you can answer.

Zero-touch is an exe typically run directly from a local network
share; but by default the system won't trust this exe - hence it
requires pre-configuration (caspol) - and (as per other post) might
shadow-copy anyway (but not permenantly).

Browser apps I would suggest fit your description, and yes: they
shouldn't install their own ActiveX without a good reason ('cos it
won't work on many browsers or platforms - Win/IE only).

Perhaps it's an application that doesn't leave dirty footprints in your
house.

You never know :)
