How to send message to each client?

[hungtt]

Hi Mone! Thanks for the reply, I've connected between metadata adapter and the data adapter through the setFeed. On the web client, I use "DynaScrollTable" to recieve messages from the "NotifyUserMessage" function on the metada adapter. Here is my code:

               var group = "im_" + userName;
			var schema = ["fromNick", "toNick", "message"];			
			var imTable = new DynaScrollTable(group, schema, "DISTINCT");			
			imTable.setDataAdapter("PROXY_HS_MARKETDATA");
			imTable.setSnapshotRequired(false);			
			imTable.setPushedHtmlEnabled(false); 
			imTable.setMaxDynaRows("unlimited");
			imTable.setUpwardScroll(true);
imTable.setAutoScroll("ELEMENT","message_scroll"); 									
			imTable.onChangingValues = function(domNode, visualUpdateInfo) {			 
			  if (visualUpdateInfo != null) {
				var from = visualUpdateInfo.getServerValue("fromNick");	
			//Don't recieve message from DataAdater 	
				alert(from); 				
			  }
			};					
			pushPage.addTable(imTable, "messages");

And here is DataAdapter Code:

  
// Call by Metadata to notify to client
public void sendMessage(string from, string to, string message)
        {
            if (localListener != null)
            {                
                IDictionary dic = new Hashtable();                                
                dic.Add("fromNick", from);
                dic.Add("toNick", to);
                dic.Add("message", message);  
                localListener.OnUpdate(dic);                            
            }
        }

I don't know why the web client doesn't receive any messages.
Thanks and Regards!
