Looping With $Variale Help

[John4]

I have a piece of code that I use to set all the checkoxes on the page to on, and another section of code to turn them off. Below is a brief chunk...

Func JobSelectAll()

GUICtrlSetState($Checkbox_2, $GUI_CHECKED)

GUICtrlSetState($Checkbox_3, $GUI_CHECKED)

GUICtrlSetState($Checkbox_4, $GUI_CHECKED)

... and on and on

All my check boxed are sequentially numbered. Is there an easier way to loop from $Checkbox_2 to $Checkbox_45 in a loop or something?

Thanks, John

Use an array

Use an array

Sorry, arrays are kind foriegn to me. Maybe a short example? Thanks, John

Does this help?

; array example

Dim $array[11]

For $i = 1 to UBound($array)
    $array[$i] = $i
    MsgBox(0,'Array:', 'Array index ' & $i & ' Value = ' & $array[$i])
Next

Instead of numbering individual variables, arrays allow you to use 1 variable for several values

Heres a short example that works with 5 checkboxes

#include <GuiConstants.au3>

Global $Checkbox[6] ;declares the the checkboxes variable is an array

$GUI = GUICreate("Checkbox Demo", 150, 250) 
$Checkbox[1]= GUICtrlCreateCheckbox("Box 1", 10, 10)
$Checkbox[2]= GUICtrlCreateCheckbox("Box 2", 10, 40)
$Checkbox[3]= GUICtrlCreateCheckbox("Box 3", 10, 70)
$Checkbox[4]= GUICtrlCreateCheckbox("Box 4", 10, 100)
$Checkbox[5]= GUICtrlCreateCheckbox("Box 5", 10, 130)
$All = GuiCtrlCreateButton("Check All", 10, 160, 130, 30)
$Clear = GuiCtrlCreateButton("Uncheck All", 10, 200, 130, 30)
GUISetState()

While 1
    $Msg= GUIGetMsg()
    Switch $Msg
        Case $GUI_EVENT_CLOSE ;people clicked close
            Exit
        Case $All ;pushed select all
            For $i = 1 to 5
                GUICtrlSetState($Checkbox[$i], $GUI_CHECKED)
            Next
        Case $Clear ;pushed uncheck all
            For $i = 1 to 5
                GUICtrlSetState($Checkbox[$i], $GUI_UNCHECKED)
            Next
    EndSwitch
WEnd

That worked great! Thanks.

Just curious, why does the Global $Checkbox[6] have to be one greater than the actual number of variables? I have 45 checkboxs and had to set the Global to 46.

Thanks again, John

because when you declare i with "$checkbox[5]" five is how many "parts" you want it to have, now it starts off counting those parts as 0

so if you used 5, you would have to make your five checkboxes

Box 0, box 1, box 2, box 3, box 4

instead of 1,2,3,4,5

I just like counting starting from 1

I thought I would add something that I just found - now why this is not the definition of an array in the help file I will never know. I am not trying to say anything about the person that created the help file, but maybe it can be redone to include some better examples - I hope not to start anything, I have said this in the past.

Here is a definition of using arrays - http://www.autoitscript.com/wiki/index.php?title=Arrays
