Writing a Client DVC Module

To write a dynamic virtual channel (DVC) client module, you must first implement and register a Remote Desktop Connection (RDC) client plug-in. The DVC plug-in is an implementation of IWTSPlugin, registered as a Component Object Model (COM) object.

Note  The plug-in must be implemented in a free-threading model. Apartment-model implementation is not supported.
 

The following is a list of interfaces that are implemented by objects that are instantiated by the plug-in.

InterfaceDescription
IWTSPlugin

Allows for the Remote Desktop Connection (RDC) client plug-in to be loaded by the Remote Desktop Connection (RDC) client.

IWTSListenerCallback

Notifies the Remote Desktop Connection (RDC) client plug-in about incoming requests on a particular listener.

IWTSVirtualChannelCallback

Receives notifications about channel state changes or data received. Each instance of this interface is associated with one instance of IWTSVirtualChannel.

 

The following is a list of interfaces that are implemented by objects that are instantiated by the Remote Desktop Connection (RDC) client, and are part of the framework.

InterfaceDescription
IWTSVirtualChannelManager

Manages all Remote Desktop Connection (RDC) client plug-ins, DVC listeners, or static virtual channels.

IWTSListener

Manages configuration settings for each listener for the DVC connection.

IWTSVirtualChannel

Controls the channel state, as well as writes on the channel.

 

The following illustration shows the relationship between the Remote Desktop Connection (RDC) client and the Remote Desktop Connection (RDC) client plug-in.
