Module Name:
RemoteDesktopClient
Abstract:
The CRemoteDesktopClient class is the parent
class for the Remote Desktop class hierarchy on the client-side.
It helps the CRemoteDesktopClientHost class to implement
the ISAFRemoteDesktopClient interface.
The Remote Desktop 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 of
.
