Dynamically calling a variable using another variable.

Recommended Posts

iizy

Hi all,

This is my first post I am a c style programmer making a small script for USB related maintenance tasks.

I would like to call a variable using the value of another variable, for example(in php):

<?php

$myvar = "foobar";

$a = "myvar";

echo ${$a};

?>

This will output "foobar"

I would like to do something similar or know if this is possible in auto before i continue writing my little script.

Thank you,

-Nick

AFAIK...

$myvar = "foobar";

$a = "myvar";

for $a to equal "foobar", No way!

Did you just mean this?

$myvar = "foobar"

$a = $myvar

msgbox(0, "Result", $a)

Edit: If not, I think your ship is sunk . . . Unless you could use a work around of some sort . . . .

AutoIt has the functions Eval, Execute and Assign. Just read the helpfile for more information.

iizy,

This should give you an idea of the range of options available in Autoit:

Dim $myvar = "foobar";

$a = Eval("myvar")
ConsoleWrite("Eval: " & $a & @CRLF)

$a = Execute("$myvar")
ConsoleWrite("Execute: " & $a & @CRLF)

Assign($a, $myvar)
ConsoleWrite("Assign : " & $a & @CRLF)

I am sure one of these meets your requirements. :-)

I thank you all for your responses Eval is what I used.

$a = "foobar"
$mytest = "a"

MsgBox(0,"",Eval($mytest))

This works as expect to output foobar.

Hope others find these posts useful.

Thank you all,

Nick

I have to apologize Nick. I did not know that code would work. I am still in shock.

Thx
