Regarding message send in singnal R

Question

Hello friends I have developed many to many chat application using signal R it is working perfectly fine.But i am getting one problem in developing one thing..that is typing message to the reciever for example:- there are two user online user x and user y.now when user x is typing message..on user y window it should come.."user x is typing message.." but when i send this message to group it is getting displayed on both screen..I want to display it on reciever screen only

This is the code

public void Send(string message, string groupName, string Istypingmessage)
{
    if (Clients != null)
    {

        string[] words = message.Split(':');
        string trim = words[0].Trim();
        string imagetag = "<img width=\"32px\" height=\"32px\" src=\"userimages/" + trim + ".jpg" + "\"" + "></img> ";
        Clients.Group(groupName).addMessage(message, groupName, words[0], imagetag, Istypingmessage);


    }
}

where here typing message=0 means normal message and 1 means "user x is typing that message" This is the key press event

 //keypress event of textbbox here..
        $(".ChatText").live('keyup', function () {
            if($(".ChatText").val().length > 0)
            {
               var messsage_typing=$("#hdnUserName").val() + " is typing...";
               var strGroupName = $(this).parent().attr('groupname');
                if (typeof strGroupName !== 'undefined' && strGroupName !== false)
                    chat.server.send($("#hdnUserName").val() + ' : ' + messsage_typing, $(this).parent().attr('groupname'),"1");

            }
        });
        //end of keypress

and this is add message code

  chat.client.addMessage = function (message, groupName,recievername,imagetag,Istypingmessage) {

            if ($('div[groupname=' + groupName + ']').length == 0) {
                var chatWindow = $("#divChatWindow").clone(true);
                $(chatWindow).css('display', 'block');
                $(chatWindow).attr('groupname', groupName);

                $("#chatContainer").append(chatWindow);
                //buggy code do not delete..
                //remove all previous li
                $('div[groupname=' + groupName + ']').find('ul li').remove();
                //replace header tag with new name
                $('div[groupname=' + groupName + ']').find('a').html(recievername);
                $("#chatContainer").draggable();
                $("#chatContainer").css('cursor','move');
            }
            if(Istypingmessage=="0")
            {
                 var stringParts = message.split(":");
                 var username = stringParts[0];
                 var message = stringParts[1];
                 //this code is for continous message sent
                 var lastliusername=$('div[groupname=' + groupName + '] ul li').eq(-2).find('div.designnone').html();               
                 if(lastliusername!=null && $.trim(username)==$.trim(lastliusername))
                 {
                    $('div[groupname=' + groupName + '] ul li').eq(-2).find('div.designmessage').append("<span class='spansameuser'>" + message + "</span>");
                    //end of this code is for continous message sent
                 }
                 else 
                 {
                    $('div[groupname=' + groupName + ']').find('ul').append("<li><div class='design'>" + imagetag + "</div><div class='designnone'> " + username + "</div><div class='designmessage'> " + message + " </div></li><li class='cleardivbetweenmsg'></li>");
                 }

             }
             else 
             {
                    $('div[groupname=' + groupName + ']').find('ul').append("<li><span>Hellos</span></li>");
             }
             $("#messages").scrollTop($("#messages")[0].scrollHeight);
        };

How can i display typing message to my reciever instead of on both screens..please help me out..In short i want to send my message only to reciever of group not to sender of the group Thanks

Answer 1

If you want to send a message to all clients in a group except for the sender, you can use Clients.OthersInGroup:

 Clients.OthersInGroup(groupName).addMessage(/*...*/);

This is the equivalent to passing the sender's connection ID as a second parameter to Clients.Group making it an excluded connection ID.

 Clients.Group(groupName, Context.ConnectionId).addMessage(/*...*/);

The method signature for Clients.Group is: public dynamic Group(string groupName, params string[] excludeConnectionIds).
