Playing a sound

How do I do to playa a sound (.mp3, .wav....) when I click a button?
Thanks!

Code:

---

Private Declare Function PlaySound Lib "winmm.dll" Alias "PlaySoundA" (ByVal lpszName As String, ByVal hModule As Long, ByVal dwFlags As Long) As Long

Private Sub Command1_Click()
    PlaySound "C:\MyFile.wav", 0&, &H1
End Sub
