Access .Net through Javascript

[Mark Broadbent]

Does anybody know of any good url references that give good examples of
accessing .net dlls or exes through Javascript. I cannot do this through
aspx or asp pages but only client side .html code.

Mark,

With a good browswer you cannot reach a database which is on the clientside
using Javascript.

Javascript is developped to protect users from that.

Cor, thanks but that is not the question I asked. I want to call .NET code
(either a dll or exe) from Javascript. The security settings on a browser
can be changed -so this should be possible.

database? ?

can you not access an the properties/methods of a .NET control running on
the client IE?
can remember syntax, but where you embed a .NET object using <object> tag,
referencing a server side .net dll and class??

Sam,

You mean probably the rich client, that was what I was thinking as well
about.

However it would need a lot of security settings from which I don't know if
it is possible. Again is the main option in my opinion when it is develloped
to prevent access to the files. That was the reason why I did not show it
earlier.

One approach is to use a webservice. So you expose your business layer thru
the webservice. On your client, you attach your javascript to the webservice
using the webservice behavior. This is strictly client-side.

Another approach is to use XML-HTTP. In this approach, you would instantiate
the xml-http object and use it to make calls into the .net layer from the
client/html page.

Both these approaches rely on IE 5+ only.
