Using a variable as an array index?

[Zachlr]

I don't remember reading that it was impossible, or that it was possible for that matter. Why won't the code below work?

$Filters_FilterNames = IniReadSectionNames(@WorkingDir & "\Filters.ini")
For $iFilter = 1 To $Filters_FilterNames[0]
    $Filters_Filter[$iFilter] = GUICtrlCreateMenuItem($Filters_FilterNames[$iFilter], $Filters)
Next

I get

Expected a "=" operator in assignment statement.:

$Filters_Filter[$iFilter] = GUICtrlCreateMenuItem($Filters_FilterNames[$iFilter], $Filters)

$Filters_Filter^ ERROR

Well, your example isn't complete enough to be sure, but declaring the array might get you a bit further along...

$Filters_FilterNames = IniReadSectionNames(@WindowsDir & "\win.ini")
Dim $Filters_Filter[$Filters_FilterNames[0] + 1]
For $iFilter = 1 To $Filters_FilterNames[0]
    $Filters_Filter[$iFilter] = GUICtrlCreateMenuItem($Filters_FilterNames[$iFilter], $Filters)
Next

first you use:

$Filters_FilterNames = IniReadSectionNames(@WindowsDir & "\win.ini")

then

$Filters_FilterNames[$iFilter]

so you have a var and array with the same name. if you look @ this source.

easy example

Local array[20]
$temp = 0

While temp > 20
    array[$temp] = $temp
    $temp = $temp + 1

But IniReadSectionNames() declares an array doesn't it?

$Filters_FilterNames = IniReadSectionNames(@WindowsDir & "\win.ini")

$Filters_FilterNames[$iFilter]

I'm not sure I quite understand what you mean. Maybe I should explain what I am trying to do first.

Upon start-up my script is supposed to read an ini file that contains information about each filter. I then creates a menu item from the section name. It also must declare a variable different from that of the filter names, so that the script can tell when it is clicked. I want to create an array of control IDs for each menu item, using a loop. The loop should repeat for each new filter name, and write a variable (the control ID) in an array.

I hope that makes a little more sense. Thanks.

Yes, IniReadSectionNames() declares and returns an array for you.

Your second array you build in your loop that consists of control ID's returned by GUICtrlCreateMenuItem wasn't declared though. Didn't inserting a Dim/Local/Global for the second array get you past this trouble spot?

Alternatively, is it just a typo? Did you mean to create the menu item and store its control ID in place of the section name in the same array? Then you just need to fix the array names to match: "$Filters_FilterNames" gets the output from IniReadSectionNames(), then you used "$Filters_Filter" inside the loop.

Doh! I was declaring a variable instead of an array. My script now works as it should. Thanks.

No, I the section names and the control IDs are both referenced later, so the need to be different. Thanks for the reply though.
