GetShortPathName for dummies

I'm trying to get certain sounds to play through the sndPlaySound API, but it won't play any sound that has a space in the directory path. I poked around for a solution, and apparently the GetShortPathName function is supposed to do the trick. Problem is, I have absolutely no idea how to implement it. I've been tinkering with VB for years, but never progressed beyond the simple stuff. (The sndPlaySound function came from a script I downloaded a while back.)

Where exactly is the function supposed to go, and what code do I need to put in?

Code:

---

Private Declare Function GetShortPathName Lib "kernel32" Alias "GetShortPathNameA" (ByVal lpszLongPath As String, ByVal lpszShortPath As String, ByVal lBuffer As Long) As Long
Public Function GetShortPath(strFileName As String) As String
    'KPD-Team 1999
    'URL: http://www.allapi.net/
    'E-Mail: [email protected]
    Dim lngRes As Long, strPath As String
    'Create a buffer
    strPath = String$(165, 0)
    'retrieve the short pathname
    lngRes = GetShortPathName(strFileName, strPath, 164)
    'remove all unnecessary chr$(0)'s
    GetShortPath = Left$(strPath, lngRes)
End Function
Private Sub Form_Load()
    MsgBox GetShortPath("c:\Program Files\")
End Sub
