Socket (gb.net)

This class implements a socket client to allow your programs to connect with socket servers. TCP and Local (Unix sockets) connections are implemented.

Symbols

This class inherits Stream in gb.

Properties		Methods
ByteOrder EndOfFile EndOfLine Handle Id		Close

This class is creatable.

Properties		Methods		Events
Host LocalHost LocalPort Path Port RemoteHost RemotePort Status		Connect Peek		Closed Error Found Read Ready

This class performs its work asynchronously, so the program will not be stopped while connecting, sending or receiving data.

This class is a derived from the class Stream, so you can use standard Stream & Input/Output functions to send and receive data, and to close the socket.

Sockets can be used if the library "gb.net" is included in the project. To include this library use the menu [Project] [Properties] [Components] tick the component "gb.net".

Example

' Gambas class file

PUBLIC MySock AS Socket

PUBLIC SUB Button1_Click()

  DIM sBuf AS String

  MySock = NEW Socket
  MySock.Connect("localhost", 7000)

  DO WHILE (MySock.Status <> 7) AND (MySock.Status > 0)
    WAIT 0.1
  LOOP

  IF MySock.Status <> 7 THEN
    PRINT "Error"
    QUIT
  END IF

  sBuf = "Hello over there.\n"
  WRITE #MySock, sBuf, Len(sBuf)

  DO WHILE Lof(MySock) = 0
    WAIT 0.1
  LOOP
  READ #MySock, sBuf, Lof(MySock)
  PRINT sBuf

  CLOSE #MySock

END

Remarks to this Example

Even if here the polling is shown, you should rather use callbacks to react on different states.
See Network Programming, the tutorial about the usage of networking. There are comments to each line of this example.
There is another example in the distribution under Networking ClientSocket.
