Socket management functions

The following functions are used to manage sockets:


SocketAccept	Run on the server, this function accepts a request for connecting to an existing socket found on the server.
SocketChangeTransmissionMode	Changes the transmission mode used on a socket.
SocketClientInfo	Allows the server to get information about the current client socket.
SocketClose	Closes a socket or a connection to a server socket.
SocketConfigure	Configures the use of Socket functions.
SocketConnect	Connects a client computer to a given socket.
SocketConnectBluetooth	Connects a client computer to a specific Bluetooth socket.
SocketConnectInfrared	Connects a client computer to a given socket via the infrared port.
SocketConnectSSL	Used to establish a secure connection to an SSL server.
SocketCreate	Creates a socket.
SocketCreateBluetooth	Creates a socket using a Bluetooth device.
SocketCreateInfrared	Creates a socket that uses the infrared port.
SocketCreateSSL	Creates a secure socket according to the SSL protocol.
SocketCreateUDP	Creates a socket that uses the UDP protocol.
SocketDeny	Run on the server, this function refuses a request for connection to an existing socket found on the server.
SocketExist	Checks the existence of socket.
SocketProxy	Specifies whether TCP sockets and WebSockets must go through a SOCKS5 proxy to execute requests.
SocketRead	Retrieves a message sent by another socket.
SocketWaitForConnection	Run on the server, this function is used to wait for a connection request coming from the client sockets.
SocketWrite	Writes a message intended to another socket.
WebSocketClientConnect	Establishes a connection between the client and a WebSocket server.
WebSocketClientConnectSSL	Establishes an SSL connection between the client and a WebSocket server.

Unit examples (WINDEV): Sending a fax

[ + ] Sending a fax with WINDEV. The fax can be sent via a fax server or via a modem properly installed and configured on the user computer.

Complete examples (WINDEV): WD Live Messaging

[ + ] This example presents the "Socket" functions of WINDEV.
The following topics are presented in this example:
1/ How to connect to a socket
2/ How to create a socket
Summary of the example supplied with WINDEV:
This example present the different functions for socket management supplied with WINDEV. To use this example, a list of contacts must be entered in your address book. The contacts must be identified by a name and the IP address of their computer. When the application is started, the program searches for the accessible contacts (which means the ones who have started this application on their computer). When you double-click a "connected" contact, a discussion window is opened, giving you the ability to communicate with the contact

Training (WINDEV): WD Using sockets

[ + ] This example presents the use of the "Socket" functions of WINDEV in Client/Server.
The following topics are presented in this example:
1/ How to connect to a socket
2/ How to accept a request for connection
3/ How to write or read on a socket
Summary of the example supplied with WINDEV:
This example presents the different functions for socket management supplied with WINDEV. To use this example, a first instance of the example must be started in "server" mode. Then, by specifying the name of the computer that will be used as server and a nickname, you can connect to this application in "client" mode. You now have the ability to send messages to all the connected users. In this example, a thread and a socket are associated with each connection.

Sample components (WINDEV): WD Trace Socket

[ + ] The purpose of this example is to trace everything that occurs on a communication via socket, on a specific address, on a specific port. This example allows you to understand the principle of dialog via socket between two applications.
Therefore, in the applications that dialog via socket, even if no trace option as implemented by the developers, you will have he ability to view all the exchanges performed on the socket.
This example also enables you to understand the operating mode of the network protocols based on the sockets: POP3, SMTP, FTP, HTTP, and so on.
Note for the users who are experienced in network communication:
This example does not allow you to trace the UDP packages (only the TCP communications can be traced).
