line 44 ImageSearch error when launching another script using ImageSearch

[dwaynek]

my 2nd script works fine when triggered on its own. but when i launch my 1st script which then triggers the 2nd script, i get a line 44 error. anyone know why that is?

 

here's my 1st script:

 

#include <ImageSearch.au3>

Run("C:\Program Files (x86)\AutoIt3\AutoIt3.exe " & chr(34) & "d:\my documents\bat\test2.au3" & chr(34))

 

here's my 2nd script:

#include <Array.au3>
#include <File.au3>
#include <Date.au3>
#include <Debug.au3>
#include <ImageSearch.au3>

Local $x, $y
Local $search = _ImageSearchArea('D:\My Documents\imagesearch\thinkorswim_7x4(1&5m).png', 1, 0, 0, 500, 400, $x, $y, 0)
    sleep(100)
    ;WinMove($hArray[$i][1], "",-3848,-8, 3856,2136)
    ;msgbox(0,"",$search)
    If $search = 1 Then
        ;msgbox(0,"","Moving to -3850,0,1936,1070")
        WinMove($hArray[$i][1], "",-3850,0,1936,1070)
        sleep(100)
        Local $pos=WinGetPos($hArray[$i][1])
        While $pos[0] <> -3850 Or $pos[1] <> 0 Or $pos[2] <> 1936 Or $pos[3] <> 1070
            WinMove($hArray[$i][1], "",-3850,0,1936,1070)
            sleep(100)
            $pos=WinGetPos($hArray[$i][1])
            ;msgbox(0,"",$pos)
            FileWriteLine($hFileOpen, "$pos: " & $pos)
        WEnd
        $cnt+=1
    Else
        ;msgbox(0,"","Moving to -1929,0,1936,1070")
        WinMove($hArray[$i][1], "",-1929,0,1936,1070)
        sleep(100)
        $pos=WinGetPos($hArray[$i][1])
        While $pos[0] <> -1929 Or $pos[1] <> 0 Or $pos[2] <> 1936 Or $pos[3] <> 1070
            WinMove($hArray[$i][1], "",-1929,0,1936,1070)
            sleep(100)
            $pos=WinGetPos($hArray[$i][1])
        WEnd
    EndIf

I think I may have come across this issue b4 playing around with image search.  You can just go into the image search au3 and change that line from if $result[0] etc to something like

if IsArray($result) and $result[0]="0" then return 0

That way it won't try to access like an array unless it's sure that it is one.

got another error after making that change...

;change this

if $result[0]="0" then return 0

; to this

if not IsArray($result) or $result[0]="0" then return 0

 

I had a feeling something like that would happen. That should fix it.

@dwaynek, can you post a copy of the ImageSearch.au3 you are using?

I suspect he is using that source. ImageSearch Usage Explanation

Here’s the thing, for ImageSearch.au3 that exact line 44 array subscript error has been encountered literally a dozen times, including in the thread you linked.

But I have used the same functions, e.g. _ImageSearchArea(), without problem.  But I am using _ImageSearch.au3 (with a leading underscore), which can be found here:

 

I think maybe it’s a newer version??

Anyway, the functions always return an array and if nothing is found then $result[0]=0, just like the error is expecting.

thanks, i tried the new version, seems to work better.
