Please suggest me any link of creating a webserver / web service in Win7CE VC# ?
Have you checked this link http://developer.toradex.com/knowledge-base/how-to-implement-ethernet-client-and-server-in-vc
You can try work with sockets from System.Net.Sockets namespace. You can use AJAX and for example XMLHttpRequest to build active page.
You can see the idea here
It’s not on C# but it’s good for understanding how to built your own web-server with sockets.
