I know this question is from way in the past but did you ever get to a solution?

I am in exactly the same place and having difficulty believing that getting a SongIterator object from the IDispatch result requires as much code as the MS manual pages seem to imply.

Please do share any solution or wisdom that you found

Regards

bump?

			
ISDBSongIterator* AllSongs = NULL;

IDispatch *iter;
iSDBApp->get_Database(&iSDBDatabase);
hRes = iSDBDatabase->QuerySongs(L"ID > 0",&iter);

if(hRes == S_OK)
{
	VARIANT_BOOL eof;
	hRes = ((ISDBSongIterator*)AllSongs)->get_EOF(&eof); //FAIL
}

if(hRes == S_OK)	
	ISDBSongData *song;
	hRes = ((ISDBSongIterator*)AllSongs)->get_Item(&song); //FAIL
}	

So I got up to Querying the DB with QuerySong, which work, but after that I don't know how to use the IDispatch returned by QuerySong,

I have tried to cast it to a SongIterator which is what it should return, but using it cause access violation.

Code:

[code]
ISDBSongIterator* AllSongs = NULL;

IDispatch *iter;
iSDBApp->get_Database(&iSDBDatabase);
hRes = iSDBDatabase->QuerySongs(L"ID > 0",&iter);

if(hRes == S_OK)
{
VARIANT_BOOL eof;
hRes = ((ISDBSongIterator*)AllSongs)->get_EOF(&eof); //FAIL
}

if(hRes == S_OK)
ISDBSongData *song;
hRes = ((ISDBSongIterator*)AllSongs)->get_Item(&song); //FAIL
}
[/code]

So i guess I cannot just cast IDispatch to ISDBSongIterator* as I did..

Can anyone help?

Btw, I am making a C++ Bridge to Sync iTunes & MediaMonkey Database
