Dynamically create variables?

[Sunaj]

Hi, I've been trying to do dynamic initialization of variables with autoit.. like so:

....
$i = 1
    While $i <= UBound($SomeArray) - 1
        $Menu & $i = GUICtrlCreateMenuItem($SomeArray[$i], $OptionsContext)
        GUICtrlSetOnEvent ($Menu & $i,"Hotkey" & $i)
        $i = $i + 1
    WEnd
....

This is obviously not working - but are there any hacks that could achieve dynamic variable initiation?

make $Menu an array.

Thanks f quick reply - unfortunately DIM'ing menu as an array produces the following errors:

==> Array variable has incorrect number of subscripts or subscript dimension range exceeded.:

$Menu[$i] = GUICtrlCreateMenuItem($SomeArray[$i], $OptionsContext)

^ ERROR

make $Menu an array.

dim $Menu[1]
$i = 1
    While $i <= UBound($SomeArray) - 1
        $Menu[$i - 1] = GUICtrlCreateMenuItem($SomeArray[$i], $OptionsContext)
        GUICtrlSetOnEvent ($Menu[$i - 1],"Hotkey" & $i)
        $i = $i + 1
    ReDim $Menu[$i]
    WEnd

Does that work?

Dude - seriously thanks a lot! - had resorted to static initialization which is just a bad solution... now its all working perfectly.

Cheers

dim $Menu[1]
$i = 1
    While $i <= UBound($SomeArray) - 1
        $Menu[$i - 1] = GUICtrlCreateMenuItem($SomeArray[$i], $OptionsContext)
        GUICtrlSetOnEvent ($Menu[$i - 1],"Hotkey" & $i)
        $i = $i + 1
    ReDim $Menu[$i]
    WEnd

Hi PsaltyDS; this looks very promising - also easier to understand the code in this way..! I am already using arrays f a lot of other data in my prg but just had trouble when it came to using them for GUICtrlCreate's (the way I did it caused errors..etc). Well, with the code below I can see that those are troubles of the past - will do implementation of this new code tomorrow. Will report back on progress, very good and easy to grasp posting you made. Thanks

You can create variables with names created in string operations, the commands are Assign() and Eval(). But in a year on this forum, and many posts on this topic, nobody yet has come up with a good reason for doing this instead of an array.

If you haven't learned arrays yet, do so. It will make everything you do with lists of data easier and more stable in the future. Do it this way with an array:

; Include statement at the top of your script
#include <array.au3>

Dim $aMenu[1]
For $i = 1 To UBound($SomeArray) - 1
    _ArrayAdd($aMenu, GUICtrlCreateMenuItem($SomeArray[$i], $OptionsContext)
    GUICtrlSetOnEvent ($aMenu[$i] ,"Hotkey" & $i)
Next
$aMenu[0] = Ubound($aMenu) - 1oÝ÷ Øíz»ay¦è½ç(uë'^¶»§³*.«Þjv«­¬¨~ö«¦åzW§Øm«¢{Z{-à­®R²íéè­zk4ߦz{´ríj)춢éí¡ûhµ©fz{¢µé¬âÓ~1éîÖØk»Múhǧº)ÿÊ'µ¨§¶¢{k¢R°Z+y§!éîצjw¯z{_ºw-è|z-쵶îd{(§þ(Z±·Ç­N,yû§rبÌ"XZ½ëhmç^rV«yÜ!Èjyèµ·¢w¢©h¢(ʦmÁ©í¶Þ¶§ØZ¶Ëkj× É.r¥v"Ûazf¥Ú(ãâ-zgîËb¢v§v+pYd0'!¢w°jËç-yÖò¶PD²§+¡«­¢+Øì%¹±ÕÍÑѵ¹ÐÐѡѽÀ½å½ÕÈÍÉ¥ÁÐ(¥¹±Õ±ÐíÉÉä¹ÔÌÐì((ìQ¡¥ÉÍÐÁÉнå½ÕÈÍÉ¥Áи¸¸()¥´ÀÌØí5¹ÕlÅt)½ÈÀÌØí¤ôÄQ¼U   ½Õ¹ ÀÌØíM½µÉÉ䤴Ä(%}ÉÉå ÀÌØí5¹Ô°U%

Actually I found a very good reason to use the Assign() and Eval() commands.

http://www.autoitscript.com/forum/index.php?showtopic=33815

I have an array that has the same name for a group of items. The array can change but the name could still exist for a different set of items. I used it to populate a TreeView control. It allowed me to assign the control a name that could exist again.

I think I used it correctly anyway.

Nice function! Having extracted your depth in $mLEN, however, I think you can derive from that exactly how many strings or array elements it will take to describe the complete tree. You have certainly shown excellent use of Assign() and Eval(), but I think it could be done with arrays. I'll give it a shot when I get some time on a Windows box.

That doesn't change the fact that you have a working function already that shows clean use of those tools. Nice job.

[sulfurious]

Thank you.

The one thing I woudl improve upon is the amount of time it takes to walk through the directory chosen. A simple program file directory is not bad, but a large directory with many subdirectories is somewhat slow.

Ups .. slow reply on this one: got everything to work as intended! For anyone wanting to use the nice example posted by PsaltyDS there's a missing ")" in this line.

....
_ArrayAdd($aMenu, GUICtrlCreateMenuItem($SomeArray[$i], $OptionsContext)) ; fixed here

Thanks f all the inputs to this post
