Sharing custom information between Publisher and Receiver

If you need to share information between two connected points we have two possible solutions: 

1. Send information via the message system

Could be implemented via SendMessageToPeer

Check out the Streamer/Receiver samples in %SDK_installation_path%\MPlatform SDK\Samples WebRTC\C#

For example: 
In the Streamer sample, we are trying to send a message via 

MainForm.cs lines 204-208

//with "" as peerID, message will be sent to all connected peers
m_objWebRTC.SendMessageToPeer("", textBoxMessage.Text);

In Receiver sample, we have a WebRTC event listener MainForm.cs lines 58-62
Where bsEventName = "message" and bsEventParam = message string value

private void M_objWebRTC_OnEventSafe(string bsChannelID, string bsEventName, string bsEventParam, object pEventObject)
  {         
           textBoxMessages.AppendText(string.Format("From: {0}, Type: {1}, Param: {2}\r\n", bsChannelID, bsEventName, bsEventParam));     
           releaseComObj(pEventObject);   
  }

2. Send information via custom properties.

Please note that all custom properties should have the prefix - "remote."

For example:

Setting the custom property 

m_objWebRTC.PropsSet("remote.CustomProps","value");

Getting the custom property

int nPeersCount;
string strPeerId, strHelp;
//Enumerate peers in room
m_objWebRTC.PropsOptionGetCount("peers_in_room", out nPeersCount);
for (int i = 0; i < nPeersCount; i++)
{
     m_objWebRTC.PropsOptionGetByIndex("peers_in_room", i, out strPeerId, out strHelp);
     int nPropsCount, nNode = 0;
     string strPropertyName, strPropertyValue = "";
     //Get exact peer properties
     m_objWebRTC.PropsGetCount("attributes_info::peers_in_room::" + strPeerId, out nPropsCount);
     for (int j = 0; j < nPropsCount; j++)
     {
           m_objWebRTC.PropsGetByIndex("attributes_info::peers_in_room::" + strPeerId, j, out strPropertyName, out strPropertyValue, out nNode);
            //Here we'll have all peer props including custom ones
      }
}
