Two words from a list, all combos.

[Auio42TheWin]

Hello people!

I've tried SO many things, but I just can't wrap my head around this... I don't see how it's possible!

How would I have a list of names ("Joe","Tom","Elizabeth","Alexander")  and then do a msgbox for each possible pair?

for i.e

Joe and Tom

Joe and Elizabeth

Tom and Elizabeth

Alexander and Joe

Tom and Alexander

Like if the list of names were in a notepad document.

what do I do? I've searched forever and came upon a few examples of something like this, and I've tried modifying them to do what I want but I can't. Here is one of them. It doesn't do what I want,  but it's something like it... i've really tried modifying it to do what I want but I can't. 

/edit - i modified it a bit to show you the kind of stuff i've tried

Run("notepad.exe")
WinWaitActive("")
Sleep(500)
$Letter = StringSplit("Alexander","Elizabeth","Tom","Jerry")
Combi("")
Func Combi($Str, $MaxLen)
Dim $i
        Send("Combination = " & $Str & @CRLF)
;       Sleep(50)
        Return
    EndIf
    For $i = 1 to $Letter[0]
        Combi($Str & $Letter[$i])
    Next
EndFunc

Put them all into an array, like you're doing, and use _ArrayPermute to get all the permutations of the elements of the array.

; Declare a 1-dimensional array, return an Array of permutations

#include <Array.au3>

Local $aArray[4] = ["Alexander","Elizabeth","Tom","Jerry"]
Local $aNewArray = _ArrayPermute($aArray, ",") ;Using Default Parameters
_ArrayDisplay($aNewArray, "Array Permuted")

Just be warned though, as you add more elements to the array, the longer it's going to take to give you any results and you'll eventually hit a point where you run out of memory.

That code is broken. (/edit: i mean the code in the OP.)

Try this:

#include <Array.au3>

$letter = StringSplit("Alexander,Elizabeth,Tom,Jerry", ",", 2)

For $x In $letter
    For $y In $letter
        If StringCompare($x, $y) <> 0 Then
            ConsoleWrite($x & " and " & $y & @CRLF)
        EndIf
    Next
Next

Note that the code above will list "Tom and Jerry" and "Jerry and Tom" as two separate outcomes. If you don't want that, try:

#include <Array.au3>

$letter = StringSplit("Alexander,Elizabeth,Tom,Jerry", ",")

For $x = 1 to $letter[0] - 1
    For $y = $x + 1 to $letter[0]
        If StringCompare($letter[$x], $letter[$y]) <> 0 Then
            ConsoleWrite($letter[$x] & " and " & $letter[$y] & @CRLF)
        EndIf
    Next
Next

Brewman, note that Auio42TheWin (whatever that may mean ) wanted pairs, not a 4-element permutation.

.... You guys are so amazing!

How do you learn how to write stuff like that? Please tell me.

How do you like... put your brain in that state? 

I sound so dumb, thank you again!

No, you do not sound dumb, you sound inexperienced. Dumb is when you fail to formulate your question carefully and still expect a useful answer.

Practice. Lots of practice. It's all a puzzle where you have a large degree of freedom in the workings of the pieces.

If you wouldn't mind, could you tell me how it works? 

I've been looking over it and trying to understand it and recreate it.

I know what this does : "$letter = StringSplit("Alexander,Elizabeth,Tom,Jerry", ",")" 

What it does is removes the commas.

Auio, you don't need to quote the entire post, it clutters the thread. Also, if you do quote, put your normal text outside of the quote box

Do you have a specific question about my code? Because it seems pretty straightforward. What is it you have trouble understanding?
