| re: How to embedd webcam control in webpage ?
You can't actually access the client's operating system when developing ASP.NET application.
The only way you'll be able to access the webcam and audio is to access the client's operating system.
To do this you'll either have to use an ActiveX control (which is not advisable because of the malicious reputation that ActiveX has earned it's self, and the fact that they only run in Internet Explorer, and the fact that only Windows users will be able to use your feature). Or you could try using Silverlight.
I recommend looking into using Silverlight for this application.
