Check if a checkbox is checked

[BALA]

#include <GUIConstants.au3>

GUICreate("My GUI Checkbox")  ; will create a dialog box that when displayed is centered

$checkCN = GUICtrlCreateCheckbox ("CHECKBOX 1", 10, 10, 120, 20)

GUISetState ()       ; will display an  dialog box with 1 checkbox

; Run the GUI until the dialog is closed
While 1
    $msg = GUIGetMsg()
    
    If $msg = $GUI_EVENT_CLOSE Then ExitLoop
Wend

How would i be able to "check" if this checkbox is checked, and cause a dialog box to open when it it checked.

Read the Help File

; Example - Press the button to see the value of the radio boxes
; The script also detects state changes (closed/minimized/timeouts, etc).

#include <GUIConstants.au3>

Opt("GUICoordMode", 1)
GUICreate("Radio Box Demo", 400,280)

; Create the controls
$button_1 = GUICtrlCreateButton ("B&utton 1", 30, 20, 120, 40)
$group_1 = GUICtrlCreateGroup ("Group 1", 30, 90, 165, 160)
GUIStartGroup()
$radio_1 = GUICtrlCreateRadio ("Radio &0", 50, 120, 70, 20)
$radio_2 = GUICtrlCreateRadio ("Radio &1", 50, 150, 60, 20)
$radio_3 = GUICtrlCreateRadio ("Radio &2", 50, 180, 60, 20)

; Init our vars that we will use to keep track of GUI events
$radioval1 = 0    ; We will assume 0 = first radio button selected, 2 = last button
$radioval2 = 2

; Show the GUI
GUISetState ()

; In this message loop we use variables to keep track of changes to the radios, another
; way would be to use GUICtrlRead() at the end to read in the state of each control
While 1
   $msg = GUIGetMsg()
   Select
       Case $msg = $GUI_EVENT_CLOSE
         MsgBox(0, "", "Dialog was closed") 
         Exit
      Case $msg = $GUI_EVENT_MINIMIZE
         MsgBox(0,"", "Dialog minimized",2)
      Case $msg = $GUI_EVENT_MAXIMIZE
         MsgBox(0,"", "Dialog restored",2)
   
      Case $msg = $button_1
         MsgBox(0, "Default button clicked", "Radio " & $radioval1 )
         
      Case $msg >= $radio_1 AND $msg <= $radio_3
         $radioval1 = $msg - $radio_1

   EndSelect
WEnd

Just use a checkbox.

So I'm replacing the radio with a checkbox?

The problem is that I don't know which Event ID to use.

$GUI_CHECKED?

If GUICtrlRead($checkCN) = $GUI_CHECKED Then

Yes. Try that.

[martin]

Yes. Try that.

The help file doesn't directly show you how to get the state of a checkbox.

Here is a simple example

#include <GUIConstants.au3>

GUICreate("My GUI Checkbox")  ; will create a dialog box that when displayed is centered

$checkCN = GUICtrlCreateCheckbox ("CHECKBOX 1", 10, 10, 120, 20)

GUISetState ()       ; will display an  dialog box with 1 checkbox

; Run the GUI until the dialog is closed
While 1
    $msg = GUIGetMsg()
   
    If $msg = $GUI_EVENT_CLOSE Then ExitLoop
    
    If $msg = $checkCN Then
        $cstate = Bitand(GUICtrlRead($checkCN),$GUI_CHECKED)
        if $cstate = $GUI_CHECKED then MsgBox(0,'','$check is checked')
    EndIf
        
Wend

Okay, it works. Ironically, I found the answer all by myself

[James]

There ya go!

I'm having this problem. What was your solution?

[sandman]

Use this:

#include <GUIConstants.au3>

$blah = GUICtrlRead($yourcheckbox)
If $blah = $GUI_CHECKED Then
   ;do stuff
ElseIf $blah = $GUI_UNCHECKED Then
   ;do other stuff
EndIf
