Spotify Grab Now Playing and Track Elapsed/Duration

Recommended Posts

Thanks to LarsJ's excellent UIASpy application I was able to grab the now playing and track elapsed / duration from Spotify in about 15 minutes


You will need junkew's CUIAutomation2.au3 from the above UDF


#include "CUIAutomation2.au3"
Global Enum $eSpotify_Elapsed = 0, $eSpotify_Duration, $eSpotify_NowPlaying, $eSpotify_Elems

Func Example()
    Local $a_oSpotify = Spotify_InitInterface()
    Local $iErr = @error
    Local $sErr = @extended
    If $iErr Then
        MsgBox(16, "Error", "Unable to parse Spotify App " & @CRLF & "Error (" & $iErr & ") " & $a_oSpotify)

    Local $sElapsed, $sDuration
    Local $sNowPlaying = ""
    Local $iElapsed = 0, $iDuration = 0

    For $j = 0 To 120
        If $iElapsed = 0 Then
            $a_oSpotify[$eSpotify_NowPlaying].GetCurrentPropertyValue($UIA_NamePropertyId, $sNowPlaying)
            $sNowPlaying = NowPlaying_Proper($sNowPlaying)
            $a_oSpotify[$eSpotify_Duration].GetCurrentPropertyValue($UIA_NamePropertyId, $sDuration)
            $iDuration = TimeStringtoSeconds($sDuration)

        $a_oSpotify[$eSpotify_Elapsed].GetCurrentPropertyValue($UIA_NamePropertyId, $sElapsed)
        $iElapsed = TimeStringtoSeconds($sElapsed)
        ToolTip($sNowPlaying & @CRLF & $iElapsed & " / " & $iDuration & "s")

EndFunc   ;==>Example

Func TimeStringtoSeconds($sHMS)
    Local $aTime = StringSplit($sHMS, ":")
    Local $iMultiplier = 1
    Local $iSeconds = 0
    If IsArray($aTime) Then
        For $i = $aTime[0] To 1 Step -1
            $iSeconds += $aTime[$i] * $iMultiplier
            $iMultiplier *= 60
    Return $iSeconds
EndFunc   ;==>TimeStringtoSeconds

Func NowPlaying_Proper($sNowPlaying)
    Local Const $sSearchNowPlaying = "Now Playing: "
    Local Const $sDelim = " by "
    Local $sProper = ""
    Local $sRes = StringReplace($sNowPlaying, $sSearchNowPlaying, "")
    Local $aRes = StringSplit($sRes, $sDelim, 2 + 1) ;$STR_ENTIRESPLIT (1), $STR_NOCOUNT (2)

    If IsArray($aRes) Then $sProper = $aRes[1] & " - " & $aRes[0]

    Return $sProper

      Hi there, 
      I'm new in AutoIt forms and using AutoIt to automate desktop application (able to automate the application normally but facing issue when I've to re-run the application twice within the same script...so need help in this please)
      here is the steps then followed by the issue in a brief : 
      1- run application . 
      2- do some actions (click menus,activate windows,set texts..)
      3- close the application. 
      4- run the application again & access the same controls.
      5- open the same windows again (like step 2)
      6- perform some validations (by getting texts from some text boxes)
      7- close the application again (and repeat 1-7 for 15 times in average )
      The issue 
      * all controls are accessible in the first run and actions done successfully on controls (for steps 1-3) BUT from the second run of the application from step-4 it's able to set focus only the main application window.
      Note: only unique properties used to while mapping the controls. 
      Error that appear in the console :
      UIAWrappers.au3" (1673) : ==> Array variable has incorrect number of subscripts or subscript dimension range exceeded.: $x = Int($t[1] + ($t[3] / 2)) $x = Int($t[1] + (^ ERROR  
      Simple spy code  of one of the controls that has this strange issue(menubar&view menu Item): 
      ;~ *** Standard code maintainable *** #include "UIAWrappers.au3" AutoItSetOption("MustDeclareVars", 1) _UIA_setVar("oP1","Title:=XXX;controltype:=UIA_WindowControlTypeId;class:=WindowsForms10.Window.8.app") ;main app form xxx _UIA_setVar("oP2","Title:=menuStrip1;controltype:=UIA_MenuBarControlTypeId;class:=WindowsForms10.Window.8.app") ;menuStrip1 ;~ $oUIElement=_UIA_getObjectByFindAll("View.mainwindow", "title:=View;ControlType:=UIA_MenuItemControlTypeId", $treescope_subtree) _UIA_setVar("oUIElement","Title:=View;controltype:=UIA_MenuItemControlTypeId;class:=") ;ControlType:=UIA_MenuItemControlTypeId;classname:=") ;~ Actions split away from logical/technical definition above can come from configfiles ;~_UIA_Action("oP1","highlight") _UIA_Action("oP1","setfocus") ;~_UIA_Action("oP2","highlight") _UIA_Action("oP2","setfocus") _UIA_action("oUIElement","highlight") ;~_UIA_action("oUIElement","click")

      Hello guys
      I would like to be able to change songs on spotify using shourtcuts on my keyboard due to the fact i don't own a keyboard with extra keys providing this feature.
      Therefor I've made a script binding my keys to make this possible, but i have a few issues and I think there is a easier or better way of creating this script. I hope someone can have a look and tell me what i could improve.
      Some of the issues are:
      I have to wait a little time before i will be able to change song right after i just changed. (I can't spam ALT + Right) Doesn't work when im inside a game. This is actually a big issue for me.  
      My current code which works:
      HotKeySet("!{left}", "Previous") HotKeySet("!{right}","naeste") HotKeySet("!{down}","current") HotKeySet("{DEL}","quit") While 1 Sleep(100) WEnd Func naeste() Sleep(400) ControlSend("Spotify", "", "", "^{right}") EndFunc Func Previous() Sleep(400) ControlSend("Spotify", "", "", "^{left}") EndFunc Func Current() Local $song = WinGetTitle("Spotify", "") TrayTip("", $song, 1) EndFunc Func quit() Exit 0 EndFunc - AliOzturk
