Module Name:
TSRDPRemoteDesktopClient
Abstract:
This is the TS/RDP implementation of the Remote Desktop Client class.
The Remote Desktop Client class hierarchy provides a pluggable C++
interface for remote desktop access, by abstracting the implementation
specific details of remote desktop access for the client-side
The TSRDPRemoteDesktopClass implements remote-desktopping
with the help of an instance of the MSTSC ActiveX client control.
