my project is based on online tutorial.We r using a external kit (using MCP 2200 Micro controller).I have to get values from this kit to my project(to textbox).kit is connected by USB port.I got the dll of the kit. There r lot of keys in this kit just like a calculater. If I press a key(say 1) in the kit,the value(1) must be shown in textbox. The thing is I want to know how to use a dll in asp .net project. I added the dll by Reference and I got the methods used in the dll. Methods r working. But the thing is I don't know the actual process to get this output value from the kit to my textbox.
i'm trying hard to get the output...

Urgency deleted: It may be urgent to you, but it isn't to us. All that your stressing the urgency does is to make us think you have left it too late, and want us to do it for you. This annoys some people, and can slow a response.

You are saying you use a asp.net project. In this case, I think it is not possible for a server (connected to your MCP) to send an update to the client (the one who displays the textbox) without any request from the client.
With a WinForm project, I can imagine 2 solutions: events or polling.
Can you precise your project and the MCP2200 API possibilities?

You should talk to the people who created it - they should provide technical support and will know more about their product than we will. If they don't, then find another supplier and demand your money back!

I already talked with the people who created it.What hey did is they send me a PDF file which explains the methods used in dll. Since the methods and all in c++ i didnt understand anything..

So talk to them again, and explain that - they are paid to help you!
