Asynchronous server socket using C#

Sun, 15 Nov 2009 00:00:00 GMT

The TcpListener class provides simple methods that listen for and accept incoming connection requests in blocking synchronous mode. You can use either a TcpClient or a Socket to connect with a TcpListener. Create a TcpListener using an IPEndPoint, a Local IP address and port number, or just a port number. Specify Any for the local IP address and 0 for the local port number if you want the underlying service provider to assign those values for you. If you choose to do this, you can use the LocalEndpoint to identify the assigned information.
Use the Start method to begin listening for incoming connection requests. Start will queue incoming connections until you either call the Stop method or it has queued MaxConnections. Use either AcceptSocket or AcceptTcpClient to pull a connection from the incoming connection request queue. These two methods will block. If you want to avoid blocking, you can use the Pending method first to determine if connection requests are available in the queue.

COM+ Automation using C#

Sat, 15 Mar 2008 00:00:00 GMT

The COM+ catalog is the underlying data store that holds all COM+ configuration data. Whenever you do any kind of COM+ administration, you are reading and writing data stored in the catalog. The only way that you can access the catalog is through the Component Services administrative tool or through the COMAdmin library.
Security
To change data on the COM+ catalog, you need to have authority as an administrator. An application using the COMAdmin objects must be running under a user account that is assigned to the Administrators role on the system application on the machine that it is trying to administer.
