INmChannelFt
Use the INmChannelFt interface methods to manage the file exchange between members of a conference.
When to Implement
You do not need to implement this interface because the NetMeeting 3 run time provides the INmChannelFt implementation on the File Transfer Channel Object. However, you need to implement the corresponding event handler methods for INmChannelFtNotify.
When to Use
Call the INmChannelFt methods from your NetMeeting client application to check the state of a file transfer channel or to set and retrieve the channel's properties. Before calling any of the INmChannelFt methods listed below, users should confirm that the NMCH_FTbit is set for this channel by using INmSysInfo::GetNmchCaps to retrieve the local system channel capabilities.
