MouseX and MouseY return coordinates with respect to the top-left corner of the user's monitor. The Window and Control classes contain MouseX and MouseY properties that are referenced to the window (in the case of the Control class, the control's parent window).

Multiple Interface Support

Multiple network interface support enables you to write applications that can bind to different NIC cards installed on a user's machine. For example, you can use this to write tunneling applications. To see what interfaces are installed on the user's machine, you can use the GetNetworkInterface method and assign the obtained interface object to a NetworkInterface property of the SocketCore class.
