Vorbis - Nov 2003 - Ogg Vorbis use in the Visual Basic .net environment

Heya everyone,

I'm planning on putting functionality into a Visual Basic program to be able
to play back Ogg Vorbis encoded multimedia files and I'm having difficulty
finding out how. Would anyone have any ideas on how I could do this? Perhaps
if I were able to use the Ogg Vorbis libraries as a .dll file and call its
functions from within the VB program - that might work. So does anyone have
any pointers on how I could go about doing this? I'm a bit new to Visual
Basic .net  :/

 

Thanks,

Ian

Well, not having used VB.NET, I don't know exactly how to import functions, 
but since you're under time pressure, here's some guesses on how to do
it.
If .NET has interfaces to DirectX, you might be able to install the 
DirectShow filters and either use some generic interface to play any 
supported files, or script Windows Media Player.  You could probably also 
script other players, including "command line" players.

As for VB syntax, the following worked a long time ago for me with VB 5 -
I'm
not sure how .NET differs, though.  It's possible .NET has a class to 
abstract external functions:

Declare Function GetSystemDirectory Lib "kernel32" Alias \
"GetSystemDirectoryA" (ByVal lpBuffer As String, ByVal nSize As Long)
As Long
