Variable Scope Issues

8 posts in this topic

I have been at this for over an hour and can't see anything wrong with the code...I have global variables declared yet variables WILL NOT UPDATE.

Any ideas guys?

 

#include <GUIConstantsEx.au3>
#include <SliderConstants.au3>
#include <WindowsConstants.au3>
#include <GuiSlider.au3>
#include <Timers.au3>
#Region ### START Koda GUI section ### Form=
Global $SlideVal = 0, $Timer = _Timer_Init()
$Form1 = GUICreate("Form1", 128, 600)
$Slider1 = GUICtrlCreateSlider(32-8, 0, 128, 600, BitOR($TBS_VERT,$TBS_TOP,$TBS_LEFT,$TBS_BOTH,$TBS_FIXEDLENGTH))
GUICtrlSetResizing(-1, $GUI_DOCKHCENTER+$GUI_DOCKVCENTER)
;GUIRegisterMsg($WM_NOTIFY, "MY_WM_COMMAND")
;GUIRegisterMsg($WM_NOTIFY, "MY_WM_COMMAND")
GUISetState(@SW_SHOW)
_GUICtrlSlider_SetThumbLength($Slider1, 64)
;Assign("SlideVal",GuiCtrlRead($Slider1),2)

#EndRegion ### END Koda GUI section ###
While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch
    If NOT GUICtrlRead($Slider1) = $SlideVal Then
        $Elapsed = _Timer_Diff($Timer)
            ConsoleWrite($Elapsed&"|"&$SlideVal&"|"&GUICtrlRead($Slider1)&@CRLF)
        If $Elapsed < 500 Then
            ConsoleWrite($Elapsed&"|"&$SlideVal&"|"&GUICtrlRead($Slider1)&@CRLF)
            $Timer = _Timer_Init()
        ElseIf _Timer_Diff($Timer) = _Timer_Diff("") OR _Timer_Diff($Timer) > 1000 Then
            ConsoleWrite($Elapsed&"|"&$SlideVal&"|"&GUICtrlRead($Slider1)&@CRLF)
            $Timer = _Timer_Init()
        EndIf
        $SlideVal = GUICtrlRead($Slider1)
    EndIf

WEnd

What is what? What is what.

It's quite difficult to tell exactly what you are trying to accomplish, but at least this reads the slider:

When using Not, wrap the expression in parenthesese e.g. Not (This == Something). There was a topic about this last week.

It's quite difficult to tell exactly what you are trying to accomplish, but at least this reads the slider:

The problem is that  even though I declared $Timer, and $SlideVal in the global scope, when I try changing it...It does not change. Basically the function of this script was to calculate the time between slider ticks. Earlier i used WM_NOFITY to do this...but the $Timer = TimerInit() was in WM_NOTIFY Function, so it was always returning about 8MilliSec no matter how  slow or fast I moved that slider. And when $Timer declaration to global scope...TimerDiff started throwing me the same value as if I executed TimerDiff("").

My goal is to create a slider that actually slides/glides with momentum, and when it hits one of the extremes (min or max) it should bounce back as if it was hitting a rubber bumper.
 

Yeah! Don't open 4 identical threads next time.

Not to be a pain, but I have had variable scope issues before, did research on the forums, and found nothing.

 

When using Not, wrap the expression in parenthesese e.g. Not (This == Something). There was a topic about this last week.

Thanks,  never figured out why NOT didn't work very well, so i usually just used "<>"

Well <> is case-insensitive, so sometimes you need to use == and Not for strings.

Biatu,

 

Not to be a pain, but I have had variable scope issues before, did research on the forums, and found nothing

That does not excuse you from creating 4 identical threads this morning. I deleted 2 of them immediately and moved the single response in the third to this thread before deleting that one too - which leaves us with just this remaining thread. :)

Now the occasional double post can easily happen because of forum latency - but 4 at one time is just spamming. Please do not do it again. ;)
