How can i get a client computer identifier in asp.net?
<p>all</p>

<p>Who can tell me how/whether I can get a client computer identifier in my asp.net/or javascript ? (The client is in network not local Intranet)</p>

<p>(What is the client computer indentifier? I think such as: Client computer MAC Address, or any hardware GUID (like CPU, Network Card, etc. )  ?)</p>

<p>Or whether any simplitify method to do it in HTML5?</p>

<p>Or whether I can get the client computer indentifier through ActiveX? (And how can i do use ActiveX, anyone who can give me some references, if the activeX can use C# to build is nice. )</p>

<p>(This is a business system, and customer is approved us to get their client computer hardware identifier, so how can i do in asp.net? )</p>
