Hi

Can any one help me out. I am trying to read from a serial port in an asp.net application.
I have downloaded and installed the ActiveX control from ActiveComport Serial Port Toolkit and have tried to implement it in the code behind, but it does not read anything..
Does any one know a way I can achieve this?

Thanks for any suggestions.

Hi Rajesh

I have tried using the serial port class but am getting authentication exception errors.
All I want to do is get the data from a serial port on a client pc into a text box on the web page.
From there I want to check that value against a values in a sql db and bring up the information on it.
Using the serial port class would be ideal. Do you have any idea how to with asp.net?

Thanks,

Chris

If it's a 3rd party library, it would be best to talk to their tech support.

Hi.,

So you want to access client Serial Port from your web pages , this leads to some security issues while accessing the client resources., but you can do it with embed Active X in your web pages., but client will get a warning while accessing this components.

Limitations:
[1] Your users will get a security warning prompting them to download the ActiveX component, even when you have had it digitally signed.

[2] If you decide to scrap your VB Comonent and go with a .NET ActiveX object, you're going to need to make sure the user has the .NET framework on his/her machine.

[3] Netscape/Mozilla is less than friendly with ActiveX components.

Thanks & Regards
