Skype4COM.dll how to determine which chat a message came from?

Question

C++ / C#

Goodnight.
There is Skype4COM.dll and the Skype conference itself, there is also a self-written auto-responder, but it works when someone writes to the conf, how to avoid this? I searched for a long time, but did not find it. In general, you need to somehow get information, namely: from where the message came from (from the user or from the conference)

Answer 1

message.chat.type

Answer 2

It’s easier to take Skype4J built under c# https://habrahabr.ru/post/263099/ (there is also an example of using it with a chat definition)
