* This example requires the Chilkat API to have been previously unlocked.
* See Global Unlock Sample for sample code.

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Socket')
loListenSocket = CreateObject('Chilkat.Socket')

* Bind to a port and listen for incoming connections:
* This example will listen at port 5555 and allows for a backlog
* of 25 pending connection requests.
lnSuccess = loListenSocket.BindAndListen(5555,25)
IF (lnSuccess <> 1) THEN
    ? loListenSocket.LastErrorText
    RELEASE loListenSocket
    CANCEL
ENDIF

* Get the next incoming connection
* Wait a maximum of 20 seconds (20000 millisec)

loConnectedSocket = loListenSocket.AcceptNextConnection(20000)
IF (loListenSocket.LastMethodSuccess = 0) THEN
    ? loListenSocket.LastErrorText
    RELEASE loListenSocket
    CANCEL
ENDIF

* Set maximum timeouts for reading an writing (in millisec)
loConnectedSocket.MaxReadIdleMs = 10000
loConnectedSocket.MaxSendIdleMs = 10000

* Send a "Hello World!" message to the client:
lnSuccess = loConnectedSocket.SendString("Hello World!")
IF (lnSuccess <> 1) THEN
    ? loConnectedSocket.LastErrorText
    RELEASE loConnectedSocket
    RELEASE loListenSocket
    CANCEL
ENDIF

* Close the connection with the client.
* Wait a max of 20 seconds (20000 millsec)
lnSuccess = loConnectedSocket.Close(20000)
