If you omit this from your method, it may solve your problem. It's quick & easy. Michael "DeveloperX" http://haywirerobotics.com/cannot-access/maven-cannot-access-class.html

Don't close your Socket until you are finished with it. The handler socket returned by EndAccept() or EndReceive() is class Socket and will dispose itself 'in silence', poor thing. However I've expected the framework to provide support for this - i.e. Object name: 'System.Net.Sockets.Socket'. http://stackoverflow.com/questions/2034582/c-sharp-cannot-access-a-disposed-object

Cheers Apr 11 '07 #4 P: n/a Michael Rubinstein The situation described by Mike is guaranteed to raise an exception in AcceptCallback() when the server socket is closed. I disassembed the System.Net.Sockets.Socket after posting this and I think I've sussed it. Cannot Access A Disposed Object C# Triggering an event or would even better.

Thanks for your help guys, this one is one of them bugs that always gets you, the ones which aren't in the code! Check If Object Is Disposed C# I've also made a couple of little changes like moving the button state code into the try blocks. I also don't see how a protected method Dispose() could be overridden in a derived class, or for that matter overriding the (non-virtual) Socket.Close(). This is created in another method just before the unsafe method call and seems purely related to tidying up some bits and pieces first.

The time now is 01:31 PM. If so, you can't do that, as the .Close() method calls dispose, and you get that error. Object name: 'System.Net.Sockets.Socket'. ..but I can't seem to handle it! Socket Async UDP - How to handle client crash Async Socket..

  6. In that sense, Win32 asynchronous socket model behaves better - no matter how the handler socket was closed, the window registered in WSAAsyncSelect() gets notification.

Check If Object Is Disposed C#

As you had it on an error the buttons would be in an unusable state. So it seems to be by design. Cannot Access A Disposed Object Sslstream The socket then would tell the 'owner' object that it is about to 'bite the dust' and since state objects should be used in callbacks anyway it should be possible to Cannot Access A Disposed Object Object Name System Servicemodel Channels Servicechannel So you hardcast a socketstateobject to a socket and wonder what's happend :confused: Try this: SocketStateObject sso = (SocketStateObject)ar.AsyncState; Socket s = sso.WorkSocket; Permalink Posted 4-Dec-09 6:03am AndyP19652.1K Updated

Both Close and Dispose could be overriden in a derived Socket class I guess to give the user a chance to tidy up their code, or wrap up the socket code I didn't mean much.

I would expect that putting a reference to it in your AsyncState would stop the GC collecting it, so are you disposing of it somewhere else?I don't have a simple answer, StackTrace: at System.Net.Sockets.Socket.BeginSend(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags, SocketError& errorCode, AsyncCallback callback, Object state)07:21 01:53 SMTPD(5c7d0001eed3fe1d) at System.Net.Sockets.Socket.BeginSend(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags, AsyncCallback callback, Object state)07:21
