_ArrayFindAll doesn't work with variable :(

Hello again dear AutoIt Community.

Today I have a problem regarding Arrays. The faulty code is shown below.

$oIE = _IECreate($idURL, 0, 1, 1, 0)
_IELoadWait($oIE)

$links = _IELinkGetCollection($oIE)

Global $aTxt[1]

Local $iIndex = 0

For $link in $links
   _ArrayInsert($aTxt, $iIndex, $link.innerText)
   $iIndex += 1
   ConsoleWrite("$Number of Texts (links) = " & $iIndex & @CRLF)
Next

If IsArray($aTxt) Then
   _ArrayDisplay($aTxt, "1D array")
EndIf

;This works
;If _ArrayFindAll($aTxt, "Fairy") Then
;   MsgBox(0, "Success", "Found all instances and saved it in an array (apparently), BUT WHERE?")
;EndIf

;This results in an error
Local $aiResult = _ArrayFindAll($aTxt, "Fairy")

If IsArray($aiResult) Then
   _ArrayDisplay($aiResult)
Else
   MsgBox(0, @error, "$aiResult is not an array." & @CRLF & "Error Code " & $aiResult)
EndIf

ConsoleWrite("The code executed without errors." & @CRLF)
Exit

The symptoms I'm experiencing are that I cannot get hold of an array that should have been created by "_ArrayFindAll". The only thing I'm presented with is an error code "-1" (sets the @error flag to non-zero).

I'd be very grateful for anyone willing to help out. Many Thanks in advance,

Also to add, There is certainly at least a dozen of instances where the Substring "Fairy" appears, so that's not the problem as I see it.

Well, without the URL I could only throw shit on a wall, but you are improperly using the return of _arrayfindall()

 

You can't:

If _ArrayFindAll($aTxt, "Fairy") Then
       MsgBox(0, "Success", "Found all instances and saved it in an array (apparently), BUT WHERE?")
EndIf

Because that's not how the return of _ArrayFindAll Works.  Just look at this code:  

#include <Array.au3>

Global $aTxt[0]

_ArrayAdd($aTxt,"")
_ArrayAdd($aTxt,"")
_ArrayAdd($aTxt,"")
_ArrayAdd($aTxt,"")
_ArrayAdd($aTxt,"")

Local $iIndex = 0

If IsArray($aTxt) Then
   _ArrayDisplay($aTxt, "1D array")
EndIf

;This works
If _ArrayFindAll($aTxt, "Fairy") Then
       MsgBox(0, "Success", "Found all instances and saved it in an array (apparently), BUT WHERE?")
EndIf

;This results in an error
Local $aiResult = _ArrayFindAll($aTxt, "Fairy")

If IsArray($aiResult) Then
   _ArrayDisplay($aiResult)
Else
   MsgBox(0, @error, "$aiResult is not an array." & @CRLF & "Error Code " & $aiResult)
EndIf

ConsoleWrite("The code executed without errors." & @CRLF)
Exit

Clearly there is no "Fairy" in the array, but the message box displays.

 

This works just fine:

#include <Array.au3>

Global $aTxt[0]

_ArrayAdd($aTxt,"Fairy")
_ArrayAdd($aTxt,"")
_ArrayAdd($aTxt,"Fairy")
_ArrayAdd($aTxt,"")
_ArrayAdd($aTxt,"Fairy")

Local $iIndex = 0

If IsArray($aTxt) Then
   _ArrayDisplay($aTxt, "1D array")
EndIf

;This results in an error
Local $aiResult = _ArrayFindAll($aTxt, "Fairy")

If IsArray($aiResult) Then
   _ArrayDisplay($aiResult)
Else
   MsgBox(0, @error, "$aiResult is not an array." & @CRLF & "Error Code " & $aiResult)
EndIf

ConsoleWrite("The code executed without errors." & @CRLF)
Exit

So clearly the problem is the wall. (your source array)

      today i liked to share an small example with you
      which it an function to read the registry values as an array
      the result array is 2d array witch
      $a_array[n][0] = value name
      $a_array[n][1] = value Data
      $a_array[0][0] = values count
      here's the function

      #include <Array.au3> #include <WinAPIReg.au3> #include <APIRegConstants.au3> Local $a_array = _RegReadToArray("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run") If @error Then     MsgBox(16, "error", @error)     Exit EndIf _ArrayDisplay($a_array) Func _RegReadToArray($s_RegKey)     Local $a_KeySplitInfo = StringSplit($s_RegKey, "\\", 2)     If UBound($a_KeySplitInfo) <= 1 Then         $a_KeySplitInfo = StringSplit($s_RegKey, "\", 2)         If UBound($a_KeySplitInfo) <= 1 Then Return (1, 1, 0)     EndIf     Local $H_KeyInfo = "", $s_RegKeyInfo = ""     Switch $a_KeySplitInfo[0]         Case "hklm", "HKEY_LOCAL_MACHINE", "hklm64", "HKEY_LOCAL_MACHINE64"             $H_KeyInfo = $HKEY_LOCAL_MACHINE         Case "hkCu", "HKEY_CURRENT_USER", "hkCU64", "HKEY_CURRENT_USER64"             $H_KeyInfo = $HKEY_CURRENT_USER         Case "hkCr", "HKEY_CLASSES_ROOT", "HKCR64", "HKEY_CLASSES_ROOT64"             $H_KeyInfo = $HKEY_CLASSES_ROOT         Case "HKU", "HKEY_USERS", "HKU64", "HKEY_USERS64"             $H_KeyInfo = $HKEY_USERS         Case Else             Return SetError(2, 2, 0)     EndSwitch     _ArrayDelete($a_KeySplitInfo, 0)     $s_RegKeyInfo = _ArrayToString($a_KeySplitInfo, "\")     Local $H_KeyInfoOpen = _WinAPI_RegOpenKey($H_KeyInfo, $s_RegKeyInfo, $KEY_READ)     Local $A_KeyInfo = _WinAPI_RegQueryInfoKey($H_KeyInfoOpen)     If @error Then Return SetError(1, 1, 0)     _WinAPI_RegCloseKey($H_KeyInfoOpen)     Local $A_RegVal[$A_KeyInfo[2] + 1][2]     Local $iV = 1, $s_RegRead = ""     While 1         $s_RegVal = RegEnumVal($s_RegKey, $iV)         If @error <> 0 Then ExitLoop         $s_RegRead = RegRead($s_RegKey, $s_RegVal)         If Not (@error) Then             $A_RegVal[$iV][0] = $s_RegVal             $A_RegVal[$iV][1] = $s_RegRead         EndIf         $iV += 1     WEnd     $A_RegVal[0][0] = UBound($A_RegVal) - 1     If $A_RegVal[0][0] >= 1 Then         Return $A_RegVal     Else         Return SetError(3, 3, 0)     EndIf EndFunc   ;==>_RegReadToArray
