Accept Connection on Socket

See more Socket/SSL/TLS Examples

Demonstrates how to create a TCP/IP socket, listen on a port, accept an incoming connection, and send a "Hello World" message to the client. Visual Basic 6.0

Dim success As Long
success = 0

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

' This example will listen at port 5555 and allows for a backlog
' of 25 pending connection requests.
