need help in iniread/write and GUICtrlCreateCheckbox

[BitByte]

I'm new to AutoIt and i'm still learning on it. i got problem in read/write for a checkbox. need advice.

#include <ButtonConstants.au3>
#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>

$Checkbox1 = IniRead("myfile.ini", "section2", "key", "1")
#Region ### START Koda GUI section ### Form=
$Form1 = GUICreate("Form1", 141, 47, 192, 124)
$Checkbox1 = GUICtrlCreateCheckbox("Checkbox1", 14, 14, 97, 17)
GUISetState(@SW_SHOW)
#EndRegion ### END Koda GUI section ###

While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
    Case $GUI_EVENT_CLOSE
        inwrite()
            Exit

    EndSwitch
WEnd

func inwrite()
    IniWrite("myfile.ini", "section2", "key", GUICtrlRead($Checkbox1))
EndFunc

can someone guide me and correct my error? thank you

BitByte,

I presume you want to save the state of your checkbox to the ini file and then read in the value to reset the checkbox on start. The code you have is nearly there...

Let us talk about the IniWrite first. When you use GUICtrlRead on a Checkbox it returns the state of the checkbox, which can be a whole range of numbers - look in the Help file for GUICtrlRead. So we really need to extract the checked/unchecked value from this composite with BitAND. You code it like this:

If BitAND(GUICtrlRead($Checkbox1), $GUI_CHECKED) = $GUI_CHECKED Then
    $CheckboxChecked = 1
Else
    $CheckboxChecked = 0
EndIf

I know it looks overcomplicated, but it is the only way when you deal with states. Then when you write your ini file, you use $CheckboxChecked as the value and you get 1 = checked, 0 = unchecked.

So, now we have the ini file written in a way we can use, let us look at how we can get the checkbox to reflect the ini value on start. Alas, your $Checkbox1 = IniRead line will not work! We need to get the stored value into a variable and then tell the checkbox what state to adopt. Take a look at this version of your code:

#include <ButtonConstants.au3>
#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>

$Initial_State = IniRead("myfile.ini", "section2", "key", "1")

#Region ### START Koda GUI section ### Form=
$Form1 = GUICreate("Form1", 141, 47, 192, 124)
$Checkbox1 = GUICtrlCreateCheckbox("Checkbox1", 14, 14, 97, 17)
If $Initial_State = 1 Then GUICtrlSetState($Checkbox1, $GUI_CHECKED)
GUISetState(@SW_SHOW)
#EndRegion ### END Koda GUI section ###

While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            inwrite()
            Exit
    EndSwitch
WEnd

Func inwrite()
    If BitAND(GUICtrlRead($Checkbox1), $GUI_CHECKED) = $GUI_CHECKED Then
        $CheckboxChecked = 1
    Else
        $CheckboxChecked = 0
    EndIf
    IniWrite("myfile.ini", "section2", "key", $CheckboxChecked)
EndFunc   ;==>inwrite

I hope everything is clear - please ask if not.
