I have tested this with four old apps with a Delphi TListBox class control (Reshacker etc.),
however, YMMV... 
 
Check that the TITLE and CLASS text are correct, or preferably,  
copy the window/control text from the au3info tool to the clipboard by double clicking the title/class/advanced mode text. 
 
Run this with the Report Access Definitions window open. 
You'll need to be running SciTE for the consolewrites. 
 
Good Luck 
 
 #Include <GuiListBox.au3>
Global $sWin = "[TITLE:Report Access Definitions; CLASS:TfrmRad]"
Global $sCtrl = "[CLASS:TListBox; INSTANCE:1]"
Global $sTxtBuf, $sTxt
Global $hParent = WinGetHandle($sWin)
ConsoleWrite('+$hParent = ' & $hParent & @CRLF)
If IsHWnd($hParent) = 0 Then Exit MsgBox(4096, "TfrmRad", "Error: Window handle not returned")
Global $hTListBox = ControlGetHandle($hParent, "", $sCtrl)
ConsoleWrite('+$hTListBox = ' & $hTListBox & @CRLF)
If IsHWnd($hParent) = 0 Then Exit MsgBox(4096, "TListBox", "Error: Control handle not returned")
For $i = 0 To _GUICtrlListBox_GetCount($hTListBox) -1
	$sTxt = "Index[" & $i & "] Text: " & _GUICtrlListBox_GetText($hTListBox, $i)
	$sTxtBuf &= $sTxt & @CRLF
	ConsoleWrite('-' & $sTxt & @CRLF)
Next
MsgBox(4096, "Report Access Definitions", $sTxtBuf)
