Socket Error 10049
Below is the code I am using. IPHostEntry localMachineInfo = Dns.GetHostEntry(Dns.GetHostName()); IPEndPoint localEP = new IPEndPoint(localMachineInfo.AddressList[0], System.Convert.ToInt32(tbPort.Text)); TcpListener listener = new TcpListener(localEP); listener.Start(); When debugging this code I notice that right after listener object is created I see error code 10042 (An unknown, invalid, or unsupported option or level was specified in a getsockopt or setsockopt call). am I missing a configuration setup ?

Best Regards, Rizwan aka RizwanSharp Friday, February 09, 2007 4:16 PM All replies 0 Sign in to vote The Socket Error Code 10042 says : Bad Protocol Option. In my point of view using TcpListener should not raise such type of exception because unlike the direct use of Socket you cannot specify wrong arguments in Constructor but TcpListener is well formed socket with right protocol selection. Â Your code also seem totally fine. I would only suggest you to see what IP is in AddressList[0], Is it a valid IP. Besides this you can also try: TcpListener listener = new Listener(IPAddress.Any, port); listner.Start(); Does this make a difference? Best Regards, Rizwan aka RizwanSharp Thursday, February 08, 2007 6:27 PM 0 Sign in to vote It did not make a difference. Actually I've just noticed that before creating the TcpListener object, I am getting error code 10045 (operation not supported) when executing the following line of code. IPHostEntry localMachineInfo = Dns.GetHostEntry(Dns.GetHostName()); <==== Error Code = 10045

Simple project, taking a picture with camera and trying to upload to web server. Every single attempt throws a 10040, message too long and no request socket error goes out. Have tried with HttpRequest and tried again tonight with sockets, always getting a 10040. Tried to change the socket buffer size and it throws a 10042: sock.SetSocketOption(System.Net.Sockets.SocketOptionLevel.Tcp, System.Net.Sockets.SocketOptionName.SendBuffer, xxxxxx) Only way I can get it to work is by splitting the byte array into several chunks and sending it over several requests, but that takes wayyyy too long. Was working with HttpRequest in 4.2, this problem started in 4.3 socket error 10054 for me... can't seem to wrap my mind around it. John Employee Reply #1 — Posted 2yr ago by John | Employee Reply #1 — Posted 2yr ago by John | Employee @johndgaf - The 10042 error is because that option is not supported in NETMF. How big is the buffer you are passing to the socket send function? Can you show a small snippet of how you send the data in chunks that is too slow? And what board are you using? johndgaf Newbie 190 exp Reply #2 — Posted 2yr ago by johndgaf | Newbie | 190 exp Reply #2 — Posted 2yr ago by johndgaf | Newbie | 190 exp I'm using a FEZ Spider. Trying to pass a camera captured picture, request is somewhere around 230 KB. I'm just splitting the picture data array into smaller arrays and sending them with a standard POST request to get it to work, but it's taking about 6 requests per picture to avoid the 10040 exception. HttpRequest request = HttpHelper.CreateHttpPostRequest("http://192.168.0.10/s/u.php", POSTContent.CreateBinaryBasedContent(picArray[upSuccess].PictureData), "image/jpeg"); request.ResponseReceived += new HttpRequest.ResponseHandler(request_ResponseReceived); request.SendRequest(); This was working in 4.2, as soon as I upgraded to 4.3 the exact same code produced the 10040. Basically now I'm just sending that same request multiple times with different post data becau
Whenever I create a new socket in either VB or C# using the following code...

ErrorCode 10042 int Can anyone shed some light on what is happening here? It is not raising an Exception in my app, but it is preventing any communication using the socket.....

I saw this too on google. This is happening when I create a new Socket object from the Dot Net framework. I have resolved the issue with my procedure and it now appears to work, although the socketexception still occurs.. I think the problem is that a TCP stream cannot broadcast like udp so tyhis is "standard" behaviour...
