Array of pointers

12 posts in this topic

Why does this happen and is there a way to create the array of pointers.? Thanks...

$aCtrl[1] = GUICtrlCreateButton("Button Test", 0, -1)
$aCtrl^ ERROR

yes. The entire code:

#include <GUIConstantsEx.au3>

Opt('MustDeclareVars', 1)

Example()

Global $aCtrl[2]
Func Example()
    Local $Button_1, $Button_2, $msg
    GUICreate("My GUI Button") ; will create a dialog box that when displayed is centered
    
    Opt("GUICoordMode", 2)
    $aCtrl[0] = GUICtrlCreateButton("Run Notepad", 10, 30, 100)
    $aCtrl[1] = GUICtrlCreateButton("Button Test", 0, -1)

    GUISetState()      ; will display an  dialog box with 2 button

    ; Run the GUI until the dialog is closed
    While 1
        $msg = GUIGetMsg()
        Switch $msg
            Case $GUI_EVENT_CLOSE
                ExitLoop
            Case $aCtrl[0]
                Run('Notepad.exe')    ; Will Run/Open Notepad
            Case $aCtrl[1]
                MsgBox(0, 'Testing', 'Button 2 was pressed')    ; Will demonstrate Button 2 being pressed
        EndSwitch
    WEnd
EndFunc   ;==>Example

Easy: change

Example()

Global $aCtrl[2]

... to:

Global $aCtrl[2]

Example()

/edit: still, this error is everything but indicative...

You declare the Global variable $aCtrl AFTER the function call, so it hasn't been seen by the script yet, so your array variable isn't declared.


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

Hello rdwray,

Actually, I don't see the array declared. I see controls assigned to an array.

You have to declare an array with its size before using it.

#include <GUIConstantsEx.au3>

Opt('MustDeclareVars', 1)

Example()

Global $aCtrl[2]
Func Example()
    Local $Button_1, $Button_2, $msg
    Local $aCtrl[2] ;Declare arrays like this or with Dim, Global
    GUICreate("My GUI Button") ; will create a dialog box that when displayed is centered
    
    Opt("GUICoordMode", 2)
    $aCtrl[0] = GUICtrlCreateButton("Run Notepad", 10, 30, 100)
    $aCtrl[1] = GUICtrlCreateButton("Button Test", 0, -1)

    GUISetState()      ; will display an  dialog box with 2 button

    ; Run the GUI until the dialog is closed
    While 1
        $msg = GUIGetMsg()
        Switch $msg
            Case $GUI_EVENT_CLOSE
                ExitLoop
            Case $aCtrl[0]
                Run('Notepad.exe')    ; Will Run/Open Notepad
            Case $aCtrl[1]
                MsgBox(0, 'Testing', 'Button 2 was pressed')    ; Will demonstrate Button 2 being pressed
        EndSwitch
    WEnd
EndFunc   ;==>Example

Edit: This worked for me

Edit: I overlooked where you had declared it, I was expecting it inside the functions, sorry. moving the declaration above the call for the function should work for you

#include <GUIConstantsEx.au3>
 
Opt('MustDeclareVars', 1)

Global $aCtrl[2]

Example()

Func Example()
    Local $Button_1, $Button_2, $msg
    GUICreate("My GUI Button") ; will create a dialog box that when displayed is centered

    Opt("GUICoordMode", 2)
    $aCtrl[0] = GUICtrlCreateButton("Run Notepad", 10, 30, 100)
    $aCtrl[1] = GUICtrlCreateButton("Button Test", 0, -1)

    GUISetState()      ; will display an  dialog box with 2 button

    ; Run the GUI until the dialog is closed
    While 1
        $msg = GUIGetMsg()
        Switch $msg
            Case $GUI_EVENT_CLOSE
                ExitLoop
            Case $aCtrl[0]
                Run('Notepad.exe')    ; Will Run/Open Notepad
            Case $aCtrl[1]
                MsgBox(0, 'Testing', 'Button 2 was pressed')    ; Will demonstrate Button 2 being pressed
        EndSwitch
    WEnd
EndFunc   ;==>Example

Are you sure? I copypasted your script and only changed the order of those two lines. That works perfectly here...

#include <GUIConstantsEx.au3>

Opt('MustDeclareVars', 1)

Global $aCtrl[2]
Example()

Func Example()
    Local $Button_1, $Button_2, $msg
    GUICreate("My GUI Button") ; will create a dialog box that when displayed is centered

    Opt("GUICoordMode", 2)
    $aCtrl[0] = GUICtrlCreateButton("Run Notepad", 10, 30, 100)
    $aCtrl[1] = GUICtrlCreateButton("Button Test", 0, -1)

    GUISetState()      ; will display an  dialog box with 2 button

    ; Run the GUI until the dialog is closed
    While 1
        $msg = GUIGetMsg()
        Switch $msg
            Case $GUI_EVENT_CLOSE
                ExitLoop
            Case $aCtrl[0]
                Run('Notepad.exe')    ; Will Run/Open Notepad
            Case $aCtrl[1]
                MsgBox(0, 'Testing', 'Button 2 was pressed')    ; Will demonstrate Button 2 being pressed
        EndSwitch
    WEnd
EndFunc   ;==>Example

Returned same error:

That's odd, because I came up with the same solution and it worked for me. If you move the declaration statement above the Example() line in the code, I get no errors.

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

@SadBunny seems like we're crossing paths today in here :x

Spammer, you were right, it is working. Our messages are getting posted in the wrong order.
