Need help with ActiveWinamp plugin

**Konrad** · 11-10-2009, 11:23 AM

I'm using AutoIt, but I guess the case should be relatively easy.

I did take a look at the plugin dll with DLL Export viewer. This is what I got:

Code:

IApplication
-----------
ChangedStatus
ChangedTrack
ChangedVolume
PlaybackEOF
CancelTimer
ExecVisPlugin
GetIniDirectory
GetIniFile
GetSendToItems
GetWaVersion
Hwmn
LoadItem
MediaLibrary
Panning
Pause
Play
Playlist
PlayState
Position
PostMsg
Previous
Repeat
RestartWinamp
RunScript
SayHi
SendMsg
SendTimeout
ShowNotification
Shuffle
Skin
Skip
StopPlayback
UpdateTitle
Volume

IPlaylist
--------
Clear
Count
DeleteIndex
FlushCache
GetSelection
Hwnd
Item
Position
PostMsg
SendMsg
SwapIndex

IMediaItem
-----------
Album
Artist
ATRString
DbIndex
Enqueue
Filename
Genre
Insert
LastPlay
Length
Name
Playcount
Position
Rating
RefreshMeta
Title
Track
GetItem
Hwnd
Item
PostMsg
RunQueryArray
SendMsg

ISiteManager
-------------
arguments
AttachEvents
Desctiption
Quit

_IApplicationEvents
-------------------
ChangedStatus
ChangedTrack
ChangedVolume
PlaybackEOF

As you can see there are a few categories:
IApplication
IPlaylist
IMediaItem
ISiteManager
_IApplicationEvents

"play" is an IApplication command. The following code works:

Code:

$winamp=ObjCreate("ActiveWinamp.Application")
$winamp.play

I guessed I could create a new object for IPlaylist, something like:

Code:

$winamp=ObjCreate("ActiveWinamp.Playlist")
$winamp.clear

This DOESN'T work, though. I had to code it like this:

Code:

$winamp=ObjCreate("ActiveWinamp.Application")
$winamp.playlist.clear

This works. So far so good. I can access application and playlist commands. Now I want to access MediaItem commands.
I thought it would work the same, like this:

Code:

$winamp=ObjCreate("ActiveWinamp.Application")
$album=$winamp.mediaitem.album

But I always get an object error. Seems I didn't understand the principle. Can someone explain it to me, plase ?

I am posting this response with zero knowledge of AutoIt, and zero knowledge of any WinAMP plugins.

Code:

$winamp=ObjCreate("ActiveWinamp.Application")
$album=$winamp.mediaitem.album

I would assume that MediaItem is going to be an item in the playlist. But which item? So my first guess is that MediaItem is an array (or collection). So maybe try MediaItem(0) or MediaItem(1)

If that's not the case, you could try being more granular.

Code:

$winamp=ObjCreate("ActiveWinamp.Application")
$mItem=$winamp.mediaitem
$album=$mItem.album

Looks like Playlist is an object under application. That makes sense as to why you need to go Application.Playlist.

"MediaItem" is NOT an object under Application, BUT there is an object called "Item" under playlist. I would guess that this is an indexed property that returns things that conform to IMediaItem

So try accessing like:

Code:

$winamp=ObjCreate("ActiveWinamp.Application")
$mItem=$winamp.playlist.item(0)
$album=$mItem.album

or 

$winamp=ObjCreate("ActiveWinamp.Application")
$mItem=$winamp.playlist.item[0]
$album=$mItem.album

(note sure if it uses () or [] for index accesses.)

Then you would obviously increment the 0 to access other items.
