从其高/低持久性ID检索iTunes Track对象 [英] Retrieve an iTunes Track object from its high/low persistent ID

问题描述

我尝试使用AutoHotkey（v1.1）和iTunes Windows 11从其持久ID检索轨道对象。脚本工作正常，直到我尝试使用 ItemByPersistentID method。

I'm trying to retrieve a track object from its persistent ID using AutoHotkey (v1.1) and iTunes Windows 11. The script works well until I try to use the ItemByPersistentID method.

objITunesunesApp := ComObjCreate("iTunes.Application")
objITunesLibrary := objITunesunesApp.Sources.Item(1)
objITunesPlaylist := objITunesLibrary.Playlists.Item(1)
objITunesTrack := objITunesPlaylist.Tracks.Item(1)

; Test if objects are OK
MsgBox, % objITunesTrack.Name ; Display the song name - OK

; Get high and low IDs
intIDHigh := objITunesunesApp.ITObjectPersistentIDHigh(objITunesTrack)
intIDLow := objITunesunesApp.ITObjectPersistentIDLow(objITunesTrack)
MsgBox, %intIDHigh% %intIDLow% ; Display: "-1071797520 -947434212" OK

; Try to get the track again using the persistent IDs
objTrackByID := objITunesLibrary.ItemByPersistentID(intIDHigh, intIDLow)
; Error:  0x80020006 - Name unknown
; Specifically: ItemByPersistentID

MsgBox, % "objTrackByID.Name: " . objTrackByID.Name ; name empty

我调用 ItemByPersistentID 办法？感谢。

推荐答案

刚刚在原始脚本中找到错误：

Just found the error in the original script:

objTrackByID := objITunesPlaylist.Tracks.ItemByPersistentID(intIDHigh, intIDLow)

ItemByPersistentID 是追踪集合的方法。
