  1. i am trying to figure out how a server can connect to a client Over the internet. In this is script. The client connects to the server on the same machine (localhost) and executes the commands from the client. How can I change that instead communicating over localhost to communicate over the internet with tcp ipaddress and a port. What i actually need help of is 1. The server will open a port and listen to communication from a No-ip address 2. I input the no-ip address and correct port in the client side, and when i click on connect, it connects to the server if its online This is the client #include <GuiConstantsEx.au3> THIS IS THE CLIENT #include <NamedPipes.au3> #include <StaticConstants.au3> #include <WinAPI.au3> #include <WindowsConstants.au3> ;
