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.
