here is a script i put together, the last login UDF post i made was badly written and i decided to reattempt the idea because i got bored
this script is much more reliable and a thousand times less confusing anyways here are the examples

;using flag 0
 
#include "Login.au3"
 
_createAccount("pieeater", "hello");Creates the account to the file "Accounts.crypt"
 
$valid = _login(0);Starts the login
 
If $valid = 1 Then;Checks the return of the login
    MsgBox(0, "Win", "you got logged in! good job!");if your login was succesful then this will run
Else
    MsgBox(0, "Lose", "you are NOT logged in!");if you failed at the login this will run
EndIf

Example 2

;using flag 1
 
_createAccount("pieeater", "hello");Creates the account to the file "Accounts.crypt"
 
$uName = _login(1);Starts the login
 
If $uName <> 1 Then;Checks the return of the login
    MsgBox(0, "Win", "you got logged in! Your username is " & $uName & "!");if your login was succesful then this will run
Else
    MsgBox(0, "Lose", "you are NOT logged in!");if you failed at the login this will run
EndIf

i know i included it in the UDF but flag 0 is used if you only want to know if the login was succesful, and flag 1 is used if you want the username returned to.

please leave suggestions since i only have 2 functions in this UDF and i would like to add to it whenever i get a chance

hope you like it,
pieeater

Nice, I once found I gui example here and started doing stuff with it and ended up with and it sort of got out of hand and I stopped working on it, but when you run it, if you right click the help icon, a little menu comes down and if you click that, you get the login box.

I like the idea behind your script so I upgraded it to use sqlite and and now its 20% cooler.

thanks for the upgrade, i've never used sqlite so ill have to have a look at the code to understand it but thanks anyway

Don't worry about understanding SQL, the script functions that were put in your script make it like 50% easier than using the crypt functions you originally had.


These are the two only functions that are relevant and matter-

_SetDataEx($Data, $Table, $Address, $UKEY = "SALT")

_GetDataEx($Table, $Address, $UKEY = "SALT")

I paste those functions to every script I make that requires managing data, and it ads a layer of difficulty by using the database, which a newbie probably won't understand right away, especially since the data in it is encrypted.

And if you'd like to encrypt stuff even more, look into CryptProtectData API, it encrypts stuff so only the user who encrypted it can fetch it back.

A have a UDF for it here somewhere in my script bank folder, gotta look for it...
