Hi,

 

You can test this code :

 

string text="Hello , do you see it ??";
   string html="<span class='MySystemMessage'>Hello , do you see it ??</span>";
   ChatPortal portal=ChatSystem.Instance.GetCurrentPortal();
   lock(portal)
   {
    ChatChannel[] channels=portal.GetStartedChannels();
    foreach(ChatChannel channel in channels)
    {
     ChatLobbyChannel lobby=channel as ChatLobbyChannel;
     if(lobby==null)
      continue;
     ChatPlaceUser[] pus=lobby.GetAllUsers();
     foreach(ChatPlaceUser pu in pus)
     {
      lobby.Manager.PushSTCMessage(pu.Connection,"SYS_ANNOUNCEMENT",null,text,html);
     }
    }
   }

 

Regards,
Terry
