Hi,

I was wondering if it were possible to call a .dll file created in .NET
from a Javascript function?

Thanks,
Roshawn
 
Roshawn,

This is not possible to call the DLL directly from Javascript as Javascript
is a client-side technology and the DLL resides on the server. You could
have Javascript post back to the page with some sort of variable in the
querystring or a hidden input and parse the postback in the code behind.

JS is not meant to execute anything that is not "client oriented". It is
there to "enhance" user experience with the wonderful internet browser.
Example: If I arrive at a website and I want to have that special
experience, then I would say, yes, please download this, say an "Activex
control", and I will risk myself to open it. However, I do not want to see
JS that executes a program behind the scene from somewhere else that I am
not aware of !

Thank you for your responses.

However, being a newbie ASP.NET programmer, I've done some reading in
the last couple of hours.

I've now learned of the uses of the <script> section of an ASP.NET page.
I understand that this section can become server-side code if marked
correctly (ie. runat="server").

Here's what I'm trying to do. Code in the <script> section would do a
particular operation. The results of that operation I'd like to use in
a JavaScript function.

Can this be done?

Thanks,
Roshawn
 
Thanks for the link.

If you all haven't noticed, there's a lot of talk on the web regarding
Google Suggest.

Wow very cool - I think a lot more sites are going to implement this
provided there is a good way to handle multi-browser support as well as the
database load.

In addition to the Javascript script remoting link I sent you, you could
also check out Dart's Live Controls. Dart Live Controls is a set of
prepackaged controls allowing dynamic client side callbacks in ASP.NET 1.1
Or I guess you could wait for ASP.NET 2.0 with it's built in IE only Client
Side Callbacks.

I'm already using the Thycotic remoting interface for a project of mine and
it works quite well and has a great price too : )
