Reading MP3/WMA Information in FoxPro

A recent post on a newsgroup was looking for a tool that would let them read MP3 tag information (artist, genre, etc). After doing some looking in the new VFP 9 "Fox Media Player" solution sample, it's simply a matter of working with the Windows Media Player COM component.

oPlayer = createobject("WMPlayer.OCX.7")
loItems = oPlayer.MediaCollection
loSong= loItems.add("c:\what time is it.mp3")
? loSong.duration
? loSong.getItemInfo("Artist")
? loSong.getItemInfo("Title")
? loSong.getItemInfo("Album")

Best of all, you can also set the information back again:

loSong.SetItemInfo("Artist","Kane Gang")

I used to rely on a variety of media tools to help catalog my music but using the WMPlayer OCX, I have placed them all into one big Fox table and from there, I update the tags, refresh my files all in a database format that I'm comfortable with.

The other benefit is that I know I'm changing the actual file instead of just some external database cache (like most players have). This makes my music collection work much better on my AudioTron or other Windows Media Center Extender devices.

There's a lot more to the WMPlayer control as well.

You can drop it onto a form and have your own player right in your application and then manage it programmatically.

CurrentPlaylist returns a collection of what's in the current playlist. There is no Add method here but instead AppendItem and InsertItem to place them at different locations in the player. These methods don't take strings to the music file though. They need to take song pointers.

loPlay= oPlayer.currentPlaylist
loSong = oPlayer.mediaCollection.add("music\what time is it.mp3")

When controlling a song, you use the Controls property

oPlayer.Controls.Play && Play the song

FYI - the PlayState property tells you what's currently happening.

0 - Undefined
1 - Stopped
2 - Paused
3 - Playing
4 - ScanForward
5 - ScanReverse
6 - Buffering
7 - Waiting
8 - MediaEnded
9 - Transitioning
10 - Ready
11 - Reconnecting

Now you can manage your entire music library properly via VFP!

Attending Southwest Fox 2019 could change your life - Find out how

Southwest Fox is coming up in October and as I do every year, I spoke with the organizers Rick , Doug and Tamar on the FoxShow. Deadlines for Southwest Fox: Super-saver price (before July 1): $695 Early-bird price (before August 1): $770 Regular price (August 1 and later): $820 This year, I took a different approach with separate shows for each organizer but the main message is still the same : July 1st is their Go/No-Go date. Conferences don't talk about this very often. I don't think developers really question if Apple will hold their WWDC in June or Microsoft will hold their Build conference - but that's because those conferences are vendor-led. Southwest Fox is a community-driven conference - it's not driven by a company with an agenda. Listen to the interviews and you can hear how important each of the organizers feel the live connection between speakers and among attendees.

Well, that explains CodePlex...

In a move that will be sure to anger open source (or rather anti-paid software, anti-Microsoft open source)  zealots, Microsoft is planning to buy GitHub . A year ago, I mused about why Microsoft would shut down CodePlex and how the world needs competing source code repositories to be strong. I'm not the only one per this Slashdot article  : "...   people have warned about GitHub becoming as large as it did as problematic because it concentrates too much of the power to make or break the open source world in a single entity, moreso because there were valid questions about GitHubs financial viability...." - Jacques Mattheij I will be interested in seeing this play out - whether developers jump ship or not. Have all the efforts Microsoft has made in pushing towards open source be seen as genuine or will all the zealots jump ship or maybe even attack? Microsoft's comment about why they shut down CodePlex referred to how spammers were using CodePlex. Well, GitHub

FoxInCloud Stats

FoxInCloud sent this link a while back about their statistics regarding visits to their site: What's interesting here is the breakdown of people. Yes, I think it's understandable that the Fox community is getting older. Another factor is the growth of the mobile and web environments taking over development. These environments really do push people towards the newer non-SQL or free SQL/hosted environments but more towards hosted storage options like Amazon and Google. A tool like FoxInCloud that helps MOVE existing applications to the cloud inherently competes with those environments. But FoxInCloud also allows developers to extend their application further by giving them a starting point using Javascript and the basic CSS (such as Bootstrap). If you're not rebuilding your application from scratch, it's certainly a great step forward. FoxPro VFP
