WPE Pro in C#?

Question

Hi, I think most of you know about WPE Pro (Winsock Packet Editor), was wondering if anyone knows how it works or has the source code of this tool? All i need is to make my own WPE Pro (clone) and add some other features to it. if anyone could provide me the basic functions of WPR Pro like read and send packet, please let me know. either PM or email me. here's the link if someone doesnt know wat is WPE Pro. http://wpepro.net/
