Thread: Playlists and ID3 tags in VB?

hey BJ, as far as m3u files go that is really easy to work out.... just open as a text file in VB, the first line ignore - m3u headder ID.

second line is the time of the track in seconds (easy to work out mins/secs from that in VB) after the comma is the mp3 title/ID3 tag, etc.

And the third line is the filename relative to the saved location of the m3u playlist.


make sense? or would a small code snippet I wrote help?

Easy! I always look at the simple stuff from a tuff way first

thanks

Bj

watch how quickly VB will crap out on u doing that with a huge file. Your best choice is to use c/c++ for this type of operation.

how big is a playlist gonna get seriously? Im using this method for playlist in excess of 500+ tracks no problems. I think the issue of VB's speed with this operation is not critical in the slightest.

not gettin worked up Charles..... go easy on VB..... it aint all bad eh?!

10 thousand mp3's in a list......no probs

thats your aim, or is that what you have tested. if tested, thats a sweet amount of playlist crunchin!

True. Tested at 9973 to be closer to the truth....it loads them within 5 secs or so. It takes 12 minutes for Winamp to make me the playlist though

Hey The only thing I can't suss, is how the hell do you get a listbox to display the extracted name, but when you click on it, refer it to the actual song file location? I can get a list full of nicely edited mp3 tags in the listbox, it's just I'm not too sure how to get the songs to reference to the actual location.....
Any ideas?

Store everything in a collection, and as you populate the list box, add the filename and index (from the listbox) to the collection. Then when you need to get the filename, just loop through the collection with the index.

For what it's worth, VB can handle arrays up to 64 Gig, so I doubt that it will have much of a problem dealing with even the largest MP3 playlist.
