Sorry, I don't have a clue what you want.


Scripts & functions Organize Includes Let Scite organize the include files

Yahtzee The game "Yahtzee" (Kniffel, DiceLion)

LoginWrapper Secure scripts by adding a query (authentication)

_RunOnlyOnThis UDF Make sure that a script can only be executed on ... (Windows / HD / ...)

Internet-Café Server/Client Application Open CD, Start Browser, Lock remote client, etc.

MultipleFuncsWithOneHotkey Start different funcs by hitting one hotkey different times

(my pirate voice) me thinks he be wanting a land lubber to translate that there code to AutoIt, hoping that ye not be disinclined to acquiesce to his request.


Spoiler

“Hello, ladies, look at your man, now back to me, now back at your man, now back to me. Sadly, he isn’t me, but if he stopped using ladies scented body wash and switched to Old Spice, he could smell like he’s me. Look down, back up, where are you? You’re on a boat with the man your man could smell like. What’s in your hand, back at me. I have it, it’s an oyster with two tickets to that thing you love. Look again, the tickets are now diamonds. Anything is possible when your man smells like Old Spice and not a lady. I’m on a horse.”

Looka a bit like Assembly code and gibberish to me.


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

How to ask questions the smart way!

I hereby grant any person the right to use any code I post, that I am the original author of, on the autoitscript.com forums, unless I've specifically stated otherwise in the code or the thread post. If you do use my code all I ask, as a courtesy, is to make note of where you got it from.
