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

Dim listenSocket As New 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.
Dim success As Boolean
success = listenSocket.BindAndListen(5555,25)
If (success <> True) Then
    System.DebugLog(listenSocket.LastErrorText)
    Return
End If

// Get the next incoming connection
// Wait a maximum of 20 seconds (20000 millisec)
Dim connectedSocket As Chilkat.Socket
connectedSocket = listenSocket.AcceptNextConnection(20000)
If (listenSocket.LastMethodSuccess = False) Then
    System.DebugLog(listenSocket.LastErrorText)
    Return
End If

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

// Send a "Hello World!" message to the client:
success = connectedSocket.SendString("Hello World!")
If (success <> True) Then
    System.DebugLog(connectedSocket.LastErrorText)

    Return
End If

// Close the connection with the client.
// Wait a max of 20 seconds (20000 millsec)
success = connectedSocket.Close(20000)

System.DebugLog("success!")
