Variable variables

[reecieboy]

Are "variable variables" possible...

I believe thats what they're called

Local $var = "Product"
Local $num = 1 ;GUICtrlRead($Product_Number)
if StringIsAlNum($num) Then
   $var & $num = "Info"
   MsgBox(0, "", $Product1)
EndIf

a variable is set from the value of both $var and $num creating $Product1

I appreciate any help on this matter as it would help me use alot less code in my current project.

Thanks in advance

Through string manipulation... Ie. Eval(), Assign(), Execute() etc.

Local $var = "Product"
Local $num = 1 ;GUICtrlRead($Product_Number)
if StringIsAlNum($num) Then
   Assign($Var & $Num, "Info")
   MsgBox(0, "", $Product1)
EndIf

You can do that with Assign(), but that's rarely a good solution. Instead, look at using array(s) to store the data. There's a Array tutorial in the wiki that may be of your interest.

Thanks to both. My intention is that i have multiple gui controls with similar handles

for example

$Product1

$Product2

$Product3

so on an so forth..

so i really need to GUICtrlRead($var & $num) if you know what i mean, I forsee that not being possible with Assign

GuiCtrlRead(Eval($Var & $Num))

There ya go.

As AdmiralAlkex already stated, it would be a better idea to use arrays here:

Dim $array[6]
$array[0] = 5
For $i = 1 To $array[0]
    $array[$i] = GuiCtrlCreateInput("...")
Next
 
;and later on:
 
For $i = 1 To $array[0]
    GuiCtrlRead($array[$i])
Next

On a side note, which may be of interest. With AutoIt, many operations will convert a number to a string automatically, and vice versa. For example the use of the operator &= will concatenate two numbers and return a string. It makes a lot of coding easier, but it can be confusing sometimes. The functions Number() and String() are sometimes needed to alter the variable type.
