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
|
||
|
|
.
