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
