stripped all the buggy stuff (i hope).
only whois and http acces in this but easy 2 implement in any script.

it contains 2 files.
1) the loader script.
2) the actual support script
both files and the pxwsa.dll should be inside the scripts/libs/ folder.

when openend you get a table called Sock with all the events/handlers/functions from the support script.

sock.lua
Code: [Select]
--[[ WsaSocket loader for PXwsa.dll from bluebear.

usage:
add the folowing line to your script.
require("libs/sock.lua")
and save this file as sock.lua inside your scripts/libs/ folder.

Sock = require("libs/WsaSocket")
if Sock then
Sock.Init()
else
SendToAll("WsaSocket", "failed to load WSA sockets library. "..
"http://www.thewildplace.dk/site/download.php?list.11"
)
end
OnWsaConnected = Sock.OnWsaConnected
OnWsaSendComplete = Sock.OnWsaSendComplete
OnWsaDataArrival = Sock.OnWsaDataArrival
