How to call Visual C dll and .Net dll at clientside?

[Tom]

I'm developing c# Asp.net application (rewriting VB6 Application)
and I have a few questions :

How to call (1) How to call dll
(2) Net dll at clientSide ?
I guess that I have to use JavaScipt.
also, will I get security messagebox each time I use it ?

Generally speaking you can't do this, at least, not natively...

This is one of the fundamental differences between an application which runs
on the desktop and one which runs in a browser. All modern browsers are
designed specifically to prevent any interaction with the hardware (and
software) of the machine on which they are running, for obvious security
reasons.

You can, of course, write an ActiveX control which can do virtually
anything, but this will mean that you will be restricted to Internet
Explorer and you will have to ramp security right down just to get the
ActiveX control to run.

Silverlight offers more possibilities, especially version 2 which is still
in beta testing:

The simplest thing is probably to explain what you're trying to do...
