I recently got into this article. It makes a chat server and people can connect to it like an AIM. The problem how would I disconnect from the server from the client. Because if I close the client application when its connected to the server it will crash the server as well. Please let me know if anyone has any solutions...
Thanks
Wherever in your code the crash is occurring, you need to set a try/catch block to catch a Connection Closed exception.

I am facing web socket issue with https://appr.tc and unable to create or join the room.
Is there any temporary break down at the server end?
its Apprtc signalling server issue. It will be back soon.
Permament solution would be to set up your own Collider server

I can find WL.Client.connect to connect a client - so far so good. How can I do the opposite however? (I have good reason to do this, rest assured.)
I think that for this purpose, what you'd actually need to do is to "restart the session" with the server. Try using WL.Client.ReloadApp.
What do you mean by disconnect? WL app does not maintain an open connection. HTTP connection is closed each time response is returned from a server. Do you mean WL.Client.logout() ?
I have a WCF service hosted in the IIS (IIS 8). The service is in a Per Call Mode and the concurrency mode is set to Multiple. I have around 600 clients connecting to it. It has a HTTPS end point. It also has a net.tcp endpoint but that is not used. Not all but some of my clients face a very weird problem. The client stops working after using for a while. I have error logging and at the client side I see the error which says
There was no end point listening at ...
There are no errors on the server, or the service. The service seems to be working fine. I can browse to the service page from a browser and other clients are still able to use the service. Running a trace is also not helping. I have spent enough time trying to figure it out but with no luck. Further more, on the same computer just restarting the client seems to work and connect to the same service. The client is a WinForms Application.
I performed a DNS flush on my machine and even that does not help.
What could be the possible issue? The things that hit my mind are that maybe the client is unable to resolve the name, but that is contradictory to it connecting in the first place.
The service maybe down, but my other clients are still using the same and they do not face problems.
It might be a problem with the client machine as it Uses Win XP but I am not sure if that would cause a problem.
Or it might be a problem because of intermittent internet connection.
Has anyone ever faced such a problem before? Some insight would be really helpful
IIS can only serve a limited number of clients at a time. It will then place additional requests onto a queue. That queue is also limited. When that queue fills up then IIS returns a 500 error, which is interpreted as "There was no end point listening at ..."
You should try this piece of code.
public void Main()
{
while(thereIsStillThisProblem)
{
var pc = new Pc();
pc.OS = new Windows2012();
pc.Start();
pc.Software.Add(new ServiceHost());
}
}

Edit: Just remembered that there is one more thing you can do, if you are using .net 4.5. I will let Jon Skeet explain.
I am new to WCF, I am trying to upload files to remote server using a windows service and WCF. When i run my code i get the below error.
An unhandled exception of type 'System.ServiceModel.EndpointNotFoundException' occurred in mscorlib.dll
Additional information: Could not connect to net.tcp://74.208.195.53:5000/. The connection attempt lasted for a time span of 00:00:21.0122019. TCP error code 10060: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 74.208.195.53:5000.
I tried using the sample project provided in this link http://www.codeproject.com/KB/WCF/WCFDownloadUploadService.aspx
I read in other blogs that, the port has to be allowed throught the firewall on the server.i did that even tried turning off the firewall on the server but it dint help.
Can someone please guide me how i could get this issue resolved.Any help would be highly appreciated. I am using win7 and the remote server is windows server 2008.
Thanks
In some circumstances you need to enable tcp on the server. this post might help
Friends,
I wrote a Socket Client which will send the Socket Server some data and get some response from Server. This process will be running once in every 2 seconds.
Now what I need to know is How we can identify the connection lost between Server and Client?
I need this to be implemented in the Client side. If there is no connection then Client should automatically close the connection. Once the connection with the server is available in the next attempt it should connect automatically.
Thanks in advance!
I'm not a vb.net developer, but this is how it works in most languages.
Writing to a lost/closed connection will fail, the client will then know that he needs to reconnect.
It's never possible to know if a connect attemt to a server will succedd before you have done it, so your client should try to reconnect in a loop with a sleep/wait period in between each connection attempt.
