MBS( "Socket.NewTCPSocket" )




Returns a new socket ID or error message.


Creates a new TCP Socket.
Socket reference numbers are starting at 29000 and counting up for each new socket.

If you call Socket.Connect, you don't need to use this method first as the connect function creates its own socket.


Create TCP Socket listening on a port:

Set Variable [$$sock; Value:MBS("Socket.NewTCPSocket")]
If [MBS("IsError")]
    Show Custom Dialog ["Failed to create Socket"; $$sock]
    Exit Script []
End If
Set Variable [$r; Value:MBS("Socket.SetNewConnectionHandler"; $$sock; Get(FileName); "NewConnection")]
Set Variable [$r; Value:MBS("Socket.SetErrorHandler"; $$sock; Get(FileName); "SocketError")]
Set Variable [$r; Value:MBS("Socket.Listen"; $$sock; TCP Receiver::ListenPort)]
If [MBS("IsError")]
    Show Custom Dialog ["Failed to create Socket"; $$sock]
    Exit Script []
End If
