You find the state of the checkbox. If the state include $GUI_CKECKED then it is checked.

$IsChecked = GuiCtrlRead($ChkBox1) = $GUI_CHECKED

EDIT: Corrected wrong advice

$IsChecked = BitAnd(GuiCtrlGetState($ChkBox1),$GUI_CHECKED)

Can you give descriptive example because still I didn't get that result. Can you know how can I know the checkbox ObjectType

Apologies, GuiCtrlGetState doesn't return with the checked state information, as the help says

Function GUICtrlGetStateFunction GUICtrlGetStateAs opposed to GUICtrlRead this function returns ONLY the state of a control enabled/disabled/hidden/show/dropaccepted

whereas GuiCtrlRead only return the checked state of a check box, as in Authenticity's example.

Here is correct way:

#include <GuiConstants.au3>

Global $hGUI
Global $CheckBox

$hGUI = GUICreate('Test', 100, 50)
$CheckBox = GUICtrlCreateCheckbox('Unchecked', 10, 15, 80, 23)

GUISetState()
While 1
    Switch GUIGetMsg()
        Case $CheckBox
            If IsChecked($CheckBox) Then
                GUICtrlSetData($CheckBox, 'Checked')
            Else
                GUICtrlSetData($CheckBox, 'Unchecked')
            EndIf
        Case $GUI_EVENT_CLOSE
            ExitLoop
    EndSwitch
WEnd

GUIDelete()
Exit

Func IsChecked($control)
 Return BitAnd(GUICtrlRead($control),$GUI_CHECKED) = $GUI_CHECKED
EndFunc

This works fine also in case checkbox has other styles than checked/unchecked at the same time - for example disabled,...

No, I think you are wrong Zedna. I used to think that but I tried GuiCtrlRead with disabled and enabled check boxes and it still gives the correct result.

#include <GuiConstantsEx.au3>

Global $hGUI
Global $CheckBox, $CheckEnable, $Btn

$hGUI = GUICreate('Test', 170, 250)
$CheckBox = GUICtrlCreateCheckbox('Unchecked', 10, 15, 80, 23)
$Btn = GUICtrlCreateButton("read checkbox state", 5, 90, 130, 22)
$CheckEnable = GUICtrlCreateCheckbox("disabled checkbox state ", 10, 150, 120, 22)
GUISetState()
$chkEnabled = True
While 1
    Switch GUIGetMsg()
        Case $CheckBox
            If GUICtrlRead($CheckBox) = $GUI_CHECKED Then
                GUICtrlSetData($CheckBox, 'Checked')
            Else
                GUICtrlSetData($CheckBox, 'Unchecked')
            EndIf
        Case $Btn
            $IsChecked = GuiCtrlRead($CheckBox) = $GUI_CHECKED
            ConsoleWrite($IsChecked & ', ' & Hex($GUI_CHECKED) & @CRLF)
            If GuiCtrlRead($CheckBox) = $GUI_UNCHECKED Then
                MsgBox(262144, "check box is", 'UnChecked')
            Else
                MsgBox(262144, "check box is", 'checked')
            EndIf

        Case $CheckEnable
            ConsoleWrite("check en" & @CRLF)
            $ChkEnabled = Not $ChkEnabled
            If $ChkEnabled Then
                GUICtrlSetState($CheckBox, $GUI_ENABLE)
                GUICtrlSetData($CheckEnable, "disabled checkbox state ")
            Else
                GUICtrlSetData($CheckEnable, "enabled checkbox state ")
                GUICtrlSetState($CheckBox, $GUI_DISABLE)
            EndIf

        Case $GUI_EVENT_CLOSE
            Exit;Loop
    EndSwitch
WEnd

I agree with you people, but here all the examples for new checkbox (that we need to create first then checking the property). That is not my question I have already a checkbox, I don't want to use GUICtrlCreateCheckbox, just I want to know the property of the existing checkbox

No, I think you are wrong Zedna. I used to think that but I tried GuiCtrlRead with disabled and enabled check boxes and it still gives the correct result.

$CheckEnable = GUICtrlCreateCheckbox("disabled checkbox state ", 10, 150, 120, 22)
GUISetState()
$chkEnabled = True
While 1
    Switch GUIGetMsg()
        Case $CheckBox
            If GUICtrlRead($CheckBox) = $GUI_CHECKED Then

lol sorry, I think we all misunderstood the subject. Lookup ControlCommand() in the help file, "IsChecked", "".
