INmChannelAppShare
Use the INmChannelAppShare interface to find running applications on the local computer that are being shared or are capable of being shared and to retrieve information about the sharing state of the local computer.
When to Implement
You do not need to implement this interface because the NetMeeting 3 run time provides the INmChannelAppShare implementation on the Application Sharing Channel object. However, you need to implement the corresponding event-handler methods for INmChannelAppShareNotify.
When to Use
Call the INmChannelAppShare methods from your NetMeeting client application to check the state of an application-sharing channel or to set and retrieve the channel's properties. Before calling any of the following INmChannelAppShare methods, users should confirm that the NMCH_SHARE bit is set for this channel by using INmSysInfo::GetNmchCaps to retrieve the local system channel capabilities.
