Hi, I'm wondering if it is possible to pass arrays to a custom function.
Code:
01: colors = red`nblue`ngreen
02: StringSplit, color_array, colors, `n
03:
04: process_array(color_array)
05:
06: process_array(passed_array)
07: {
08:     global
09:     MsgBox %passed_array1%
10:    ;MsgBox %color_array1%
11: }

This does not recognize the passed array. I like to avoid calling the direct array name like the line 10. Is there a way to do it?

Code:
colors = red`nblue`ngreen
StringSplit, color_array, colors, `n

process_array(color_array)

process_array(passed_array)
{
    global
    MsgBox % %passed_array%1
   ;MsgBox %color_array1%
}


Is that what you want?

No, I mean I'd like to retrive the array elements in the function.

In this case, I've expected the code above would return 'red' because %passed_array1% corresponds to %color_array1%, but it doesn't.

Pass the name of the array as literal text. The variable color_array has no value.
Code:
colors = red`nblue`ngreen
StringSplit, color_array, colors, `n

process_array("color_array")
return

process_array(passed_array)
{
    global
    MsgBox % %passed_array%1
   ;MsgBox %color_array1%
}

thanks jaco, I never imagined it could be done that way.

So, here is my script which checks if a passed array contains repeated elements. Regarding the line 14 and 16, why couldn't they be written in an usual way like %arrayname0% and arrayname%A_Index%?

Code:
01:   colors = red`nblue`ngreen`nred`n
02:   StringSplit, color_array, colors, `n
03:
04:   if chk_same_element("color_array")
05:      MsgBox True
06:   else
07:      MsgBox False
08:      
09:   chk_same_element(arrayname)
10:   {
11:      global
12:      num_chk := %arrayname%0
13:      counter := 0
14:      Loop, %num_chk% ;1. Loop, %arrayname0% didn't work
15:      {
16:         array_element%A_Index% := %arrayname%%A_Index%   ;2. arrayname%A_Index% didn't work
17:         if array_element%A_Index%
18:         {
19:            counter += 1
20:            chked_elements%counter% := array_element%A_Index%
21:         }
22:      }
23:      repeated =
24:      Loop, %counter%
25:      {
26:         chkelement := chked_elements%A_Index%
27:         scan_number := A_Index
28:         Loop, %counter%
29:         {   
30:            if (A_Index = scan_number)
31:               continue
32:            else if (chkelement = chked_elements%A_Index%)
33:            {
34:               repeated := true   
35:               break
36:            }   
37:         }
38:      }
39:      if repeated
40:         return true
41:      else
42:         return false
43:   }

oh, sorry for the empty post, seems like the forum doesn´t like some links.

to cut it short: you are dereferencing in these lines. check:
Code:

and please don´t put line numbers in front of your code, it´s annoing. Thanks

There was a small pow-wow about this a few months ago, the easiest way to enter the link in and have the forum display it properly is to use %28 and %29 in place of the left and right parenthesis in the URL.
