McAfee and Async Sockets

Possible Problem With Sockets 2.0 Implementation in .NET 2 with McAfee Software?

McAfee (Privacy Filter and Personal Firewall) installs it's own TCP/IP driver layer. This new driver does not seem to support sockets correctly. When attempting to connect to a remote server IPv4 TCP/IP using the Async BeginConnect you get "not supported on this object type" (unistall the Mcafee driver and it all works fine). If you do a sync connect using Connect the connection is established . However, if you then try to do an async send after connecting you don't just get an exception you get a full blown unmanaged general protection fault. This seems to be a pretty big problem has anyone else out there experienced it or maybe got a work around?

I'd guess they don't support binding to a completion port, or something like that. In the first instance complain to McAfee since their stack is at fault. It's possible that the kernel simply has a specific list of things that can bind to completion ports.

For some uses of the asynchronous pattern, .NET queues a work item to the thread pool and simply runs the synchronous version on the thread pool thread. For sockets, it's different: asynchronous I/Os are used. If the OS supports it - NT, 2000, XP, 2003 and successors - the socket is bound to a completion port which is a highly scalable way of receiving I/O completion notifications; otherwise it uses overlapped I/Os. In any case, the notification that the I/O is complete ends up on the thread pool, which then calls your callback function.

.NET 2.0 adds a new property to the Socket class which can be used to force the overlapped I/O mechanism and turn off the completion port feature: UseOnlyOverlappedIO. Set to true to stop it using the completion port. This may work around the problem, but McAfee really should fix it - .NET 1.x will always use the completion port if it's available.

Thanks for your help, I tried enabling the UseOnlyOverlappedIO property on the Socket but it did not seem to have any impact. When the BeginConnect is executed I still receive the error "The attempted operation is not supported for the type of object referenced". If I remove McAfee this line works fine. Below is a code snippet in case I am missing something. I have raised this with McAfee and Microsoft but I suspect it's going to be a case of bug ping pong for a while.

// Create remote end point and prepare socket (m_sHost="www.google.co.uk" m_iPort=80)<br />
ipendRemote = new IPEndPoint(Dns.GetHostEntry(m_sHost).AddressList[0], m_iPort);<br />
m_sockDestination = new Socket(ipendRemote.AddressFamily, SocketType.Stream, ProtocolType.Tcp);<br />
<br />
// Attempt Mcafee fix<br />
m_sockDestination.UseOnlyOverlappedIO = true;<br />
                <br />
// Start the connection process<br />
m_sockDestination.BeginConnect(ipendRemote, new AsyncCallback(this.OnConnected), m_sockDestination);

I've just seen a blog post[^] by the Windows Networking development team talking about how Layered Service Providers behave with a mix of different sockets. This might have some impact on your problem, I'm not sure.

If you're still having the problem, you could try posting a comment to that blog entry.

Hi to all,
How to run an exe of a code written in .Net Framework, on an PC without having installed .Net on it?

Basically, you can't. Without the .NET Framework, none of the classes that you are using in your code exist and, therefore, the code won't run. You have to install the framework.

Create a deployment project by selecting: File/New/Project/Other project types/Setup and Deployment

From here you can use the wizard or just select the setup type. You can make a requirement that the target have the framework installed. If it does not, then it you can select it to go out the internet and download or you can provide the file in your deployment. You can download the dotnetfx.exe (.Net Framework 2.0 Redist) from the Microsoft downloads site.

I have one vb.net windows application with one form; this is a small utility program. This Zip the content of the specific folder in a certain interval and copy the content in to some other place & keep the folder empty always. While running the application this sits in System tray as icon. This runs in the server always (24 X 7). This application I want to run as a windows service, because when ever server gets restarted, I have to run this application manually.

I tried to put this in windows service, it's running, but my problem is, I don't know how to launch the system try icon while running the service. I want once the service starts; my utility exe icon should come in system tray. Help me out in this.

Thanks,
Rajasekaran.

Add a Notify Icon control to your service or VB form. This Notify Icon with sit on System Tray. Handle certain click events with this control.

If necessary, and a Context Menu control in association with the Notify Icon. Add as many Menu Items as you wish. Handle a click event with each Menu Item.

The constructor of ObjectDisposedException take a mandatory string argument.
I never know what string to use and I tend to use the following:
"this"
GetType().Name
"Handle"

What is it supposed to be?

Well just include something the receiver can use to evaluate what exactly happend. When using Controls for example it should most probably be the Name of the Control. 'This' and 'handle' are in my opinion rather bad. The receiver of the exception will immdiately aks himself: What handle?!?
So just take something descriptive. Instead of using some non saying constant you could better make the parameter Null (which is allowed in this case - ObjectDisposedException will create a slightly different message).

I did a test and Control, for example, return the Class name (that is: "Control", I think I will do that...)
it's obvious with the stack trace anyway! D'Oh! | :doh:

Use the following namespaces:
