Calling _ArraySearch; with 2D array; getting error.

[agreiner]

I have an array ($variables), which has 2 dimensions (0 = name, 1 = value). I am trying to search the array to return the value for a given name. I know that I missing something very simple, yet I have no idea what it is.

_ArraySearch($variables,$name,0,0,0,0,0,0)

When I try to run this, I get:

ERROR: _ArraySearch() previously called with expression on Const ByRef param(s).

Can someone point me in the right direction?

Thanks

agreiner,

Welcome to the AutoIt forum.

Please post all of your script - there is something wrong with the way you have declared $variables and/or $name by the look of it.

Edit: And it looks as is you have not set the $iSubItem parameter correctly if you are looking for the second column.

P.S. When you post code please use Code tags. Put [autoit] before and [/autoit] after your posted code.

Unfortunately, I am not allowed to post all of my code (non-disclose agreement); however, I will work on extracting the important bits and see if I can reproduce the issue (that way I can post it, without violating my non-disclose).

agreiner,

Fine - but we need some working(ish) code which demonstrates the same problem.

Melba,

Thanks for the help. You resolved my issue with:

there is something wrong with the way you have declared $variables and/or $name by the look of it.

While attempting to reproduce this issue, I realized that I had declared $variables as Global, then tried to declare it again in the Local scope, later in the script. This code works:

#include <Array.au3>
;Create the XML Object
$o = ObjCreate("Msxml2.DOMDocument")
$o.load("C:\Documents and Settings\agreiner\Desktop\forumexample.xml")
$o.setProperty("SelectionLanguage", "XPath")
$oVariables = $o.selectNodes("//test/variables/variable")
;Count the variables
$varcount = 0
For $oVariable In $oVariables
$varcount+=1
Next
;Declare variables array
Global $variables[$varcount][2]
;populate the variables array
$i = 0
For $oVariable In $oVariables
$variables[$i][0] = _NodeGetValue($oVariable.attributes.getNamedItem("name"))
$variables[$i][1] = _NodeGetValue($oVariable.attributes.getNamedItem("value"))
$i+=1
Next
;sort the array alphabetically by variable name (not needed)
;_ArraySort($variables,0,0,0,0)
MsgBox(0,"Var1",VariableFindValue("Var1"))
Func VariableFindValue($name)
$check = _ArraySearch($variables,$name,0,0,0,0,1,0)
If $check < 0 Then
  Return @error
EndIf
Return $variables[$check][1]
EndFunc
Func _NodeGetValue(Const $oNode, $vDefault = "")
    If Not IsObj($oNode) Then Return SetError(1, 0, $vDefault)
    Return $oNode.value
EndFunc

Edit: I guess an xml snippet may be useful as well:

<?xml version='1.0' encoding='UTF-8'?>
<test>
<variables>
  <variable name="var3" value="0"/>
  <variable name="var2" value="2"/>
  <variable name="var1" value="8"/>
  <variable name="var5" value="5"/>
  <variable name="var4" value="6"/>
</variables>
</test>

agreiner,

Nice to see the remote debugging skills are still up to scratch!
