I need some help with playing a sound file via the MCI Windows API. I added this line to my VB .net "Module"...

Code:
Public Declare Function mciSendString Lib "winmm.dll" Alias "mciSendStringA" (ByVal lpstrCommand As String, ByVal lpstrReturnString As String, ByVal uReturnLength As Integer, ByVal hwndCallback As Integer) As Integer
and I am attempting to call it via a Public Sub called PlaySoundFile.. like this:

Code:
Public Sub PlaySoundFile(SoundFile As String)
Call mciSendString("open " & SoundFile, CStr(0), 0, 0)
Call mciSendString("play " & SoundFile, CStr(0), 0, 0)
End Sub
But it is not working.. what am I doing wrong? I am trying to use it in a command button like this:

Code:
Call PlaySoundFile("C:\Users\PathToSoundFile")
