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.
