LittleEndian = True Var writeFile As FolderItem = FolderItem. ShowOpenFileDialog ( 'text' ) If readFile Nil Then Var ReadStream As BinaryStream = BinaryStream. This functionality is used for various protocols, such as FTP. Then you can check the Port property to see which port the OS picked. In that case, the OS will pick a port for you and listen on it. This trick can be very useful when you do things like Listen on port 0. This will be a random-seeming port number. Or, if you connect to a socket on port 8080, once the connection occurs, you can check to see what port the OS has bound you to. You need to set the port property explicitly before any call to Listen or Connect as the Port property will be modified to reflect what the actual bound port is during the various stages of operation.įor instance, if you listen on port 8080 and a connection comes in, you can check the Port property to ensure that you're still listening on port 8080 (that the port hasn't been hijacked). This is due to security features built into the underlying OS. On most operating systems, attempting to bind to a port less than 1024 causes a Error event to fire with an error number 107 unless the application is running with administrative permissions. The Password to use to log into the SMTP server. This example specifies that the TCPSocket will use the first Network Interface on the user's computer. If you wish to send broadcast packets out, then you should not bind to a specific interface because the behavior is undefined. The behavior is OS-dependent it appears to work on Windows but not on other supported operating systems.

In the case of UDPSockets, if you assign a non- Nil value, the socket may not be able to receive broadcast messages. Leaving this property set to Nil will use the currently selected interface. You can get the network interface(s) of the user's computer by calling the GetNetworkInterface method of the System module. Specifies which network interface the socket should use when binding.
