Dear friend,

1.
i need to work out with a device DLL (it has events, methods, properties) on client machine,
whereas the data for this device is from database (ASP .NET)...

i need to create a new object from a DLL class, add the event handler, add the event trigger, methods and properties..
and especially this DLL will listen to USB port, send status all the time and trigger event if a card is detected.

could you pls tell me how to do it in Javascript ?

below is the source code in windows app (C#), but i can not find
sample code to do it in JavaScript...

Thank you,

hendy
