reference a variable within a variable

[dwaynek]

is there a way to reference a variable name via a variable?

eg i want to create a bunch of radio buttons but instead of doing :

$radio1 = GUICtrlCreateRadio ("this is radio1", 10, 10)

for each radio button... i want to do something like:

$i=0

$top=10

while $i < 10

$i=$i+1

$radioname = "$radio" & $i

MsgBox(0, "", $radioname)

$radioname = GUICtrlCreateRadio ($avArray[$i-1], 10, $top)

$top=$top+20

WEnd

but the problem is when i get to:

Case BitAND(GUICtrlRead($radio1), $GUI_CHECKED) = $GUI_CHECKED

it reports that $radio1 is not a defined variable.

any ideas?

This line

$radioname = "$radio" & $i

sets $radioname to have the value $radio1 if $i is 1 etc. It doesn't change the variable name.

When you later say

$radioname = GUICtrlCreateRadio ($avArray[$i-1], 10, $top)

then $radioname now has the value which represents the radio button and no longer the value $radio1.

What you need, and what might not be obvious from the link EndFunc gave you, is an array.

Hers's how you code could be changed to use an an array of radio buttons.

Dim $radioButton[10]; assume we want no more than 10 of them
$i=0
$top=10
while $i < 10
    MsgBox(0, "", "$radioButton[" & $i & "]"
    $radioButton[$i] = GUICtrlCreateRadio ($avArray[$i-1], 10, $top)
    $top=$top+20
        $i=$i+1;<--- I moved this line to the end of the loop
WEnd

;Then there should be no problem when you get to

Case BitAND(GUICtrlRead($radioButton[1]), $GUI_CHECKED) = $GUI_CHECKED

this is awesome! exactly what i needed.
