Hi,

 

It's been a while since I've used AutoIt, but I'm having fun with it again.

I'm running on Windows 7 Pro, 64_bit. with AutoIt 3.3.14.2+ 

 

In my program, I've called Winlist(), so that I can get a list of all windows on the system.

I then iterate through the titles, and attempt to copy the title & handle of Windows I'm specifically interested in.

While this seems to be a very easy task, I'm having a strange problem copying the title & handle of the two windows that I'm interested in.

In the For loop: 

For $i = 1 To $AllWindowsCount

ConsoleWrite() displays the expected Title & handle, from the WindowsDupe array, so it appears that the copy from the $AllWindows array

works as expected.

However, when 

_ArrayDisplay($WindowsDupe)

is called after the for loop, $WindowsDupe is empty.

 

I wasn't able to find any functions in the help file, for copying entire arrays or certain elements, so I thought I would just copy them manually, as seen in the for loop.

What am I doing wrong with the WindowsDupe array?

 

Thanks

 

Thanks

 

My code is attached.

cappy2112,

The information is there, but because you make the Dupe array as big as the WinList return, the found data is hidden somewhere within it. Best to do something like this: 

#Region ;**** Directives created by AutoIt3Wrapper_GUI ****
    #AutoIt3Wrapper_Run_Tidy=y
#EndRegion ;**** Directives created by AutoIt3Wrapper_GUI ****
#include <MsgBoxConstants.au3>
#include <AutoItConstants.au3>
#include <Array.au3>

_Main()

; ******************************
; GLOBAL SETTINGS
;
AutoItSetOption("WinTitleMatchMode", 2) ; match ANY substring in the title
Break($BREAK_ENABLE)
;
; ******************************


Func FindAllWindows($titlematch)

    Local $NonHIWindowCount = 0
    Local $AllWindowsCount = 0
    Local $AllWindows
    Local $i
    Local $WindowsDupe[1][2] = [[0]]
    Local $TitleMatchCount = 0
    Local $temp

    $AllWindows = WinList()

    _ArrayDisplay(WinList)

    $AllWindowsCount = $AllWindows[0][0]
    MsgBox($MB_OK, "WINDOW COUNT", "There are " & $AllWindowsCount & " Windows")

    $TitleMatchCount = 0
    For $i = 1 To $AllWindowsCount

        If StringInStr($AllWindows[$i][0], $titlematch) <> 0 Then
            $TitleMatchCount += 1
            ReDim $WindowsDupe[$TitleMatchCount + 1][2]
            $WindowsDupe[$TitleMatchCount][0] = $AllWindows[$i][0] ; copy this HI window's title
            $WindowsDupe[$TitleMatchCount][1] = $AllWindows[$i][1] ; copy this HI window's handle
        EndIf
    Next

    ;$WindowsDupe[0][0] = $TitleMatchCount
    _ArrayDisplay($WindowsDupe, "Dupe array", Default, 8)

    Return $WindowsDupe ; return a list of all windows

EndFunc   ;==>FindAllWindows


Func _Main()


    Local $wHnd
    Local $hiWindowList
    Local $WindowCount
    Local $WindowList

    $WindowList = FindAllWindows("Untitled - Notepad")
    _ArrayDisplay($WindowList, "Returned", Default, 8)

    MsgBox($MB_OK, "AFTER RETURN", "RETURNED FROM FINDALLWINDOWS()")


EndFunc   ;==>_Main

Now the Dupe array is only as large as it needs to be.

Edit: I see JohnOne had the same idea.

ReDim $WindowsDupe[(UBound($AllWindows))  -1][2]

Why? All of the examples I've seen- including in the help file,
always show UBound(Array) +1.

Isn't dimension [2] out of bounds, for a 2D array??

 
 ReDim $WindowsDupe[$TitleMatchCount + 1][2]
 Please explain dimension [2], since this is a 2D array. Do array indices start at 0 or 1, in AutoIT?
