Hi guys,

I am developing a web page in which I want to allow the user to run a DLL which is present in the client PC.The Dll performs some functions on the client PC and gives back information to the User on the Web Form itself.

I currently have idea of only to run the DLL on the server side and getting the values on the clients Web Form but for the above situation which is quite opposite to this one, I dont have any clues.

Can Remoting provide the solution?

Can nebody tell me how to do that?
Thanks in advance

Regards,
SANJAY KABRA

ASP.NET on server == HTML on the client.

You will have to have the user download something, or you'll need to write some kind of clientside user control (.htc) or a java applet or....

Long story short, you are limited to what you can do in HTML, JavaScript and Client plugins. However, what about using some web services? If the client downloads a small program, it could talk to your web application thru web services directly to the server.

Hi plonie,
Thanks for prompt response. About the WebService I am thinking this way.

When the Client Opens the Web Page he will have a download link which will download a Windows Services DLL and register and run that windows service.
This service on running will run the DLL present in the client PC and the information obtained from that client DLL will be passed on to the Web Service on the Server. But the whole process should occur in the background. In the mean time, user on the Web Page will be getting "Wait.." message.

When the WebService gets the Information from the client it has to notify and fill the page opened by the client with the retrieved information

I hope you got the whole scenario.

Now the questions are.
How the Windows Services will be downloaded, installed and run silently by just clicking a button on the Web Form?
Can the Windows Service run another DLL?
Can the Windows Service pass the information to the WebService on the Server?
How will the WebService notify the WebPage on the Client PC,about the retrieved information

Question:
1) Here lies the main problem. There are major security restrictions that prevent this from happening. If there weren't, then there would be nothing to preventing me from writing a little program that formats your hard drive, or something equally destructing. You'll need to write some kind of component that downloads. I don't know plugins are written in and how they are downloaded, but that's essentially what you need to do.

2) Once the client has your program on their machine, it can call other programs on their machine.

3) The program they download could most certainly call your web service and pass it information.

4) This is another problem. The web service will be called by the client side program, so it can't tell the browser where to go. You'll need to write something in the program running on the client that points the browser to a page. I don't know how to do this.
