If you are using the MCI OCX, you can invoke the Command method with the "Eject" command

MCI1.Command = "Eject"

To open and close CD-Drive door through Visual Basic:

--
Private Declare Function mciSendString Lib "winmm.dll" Alias "mciSendStringA" (ByVal lpstrCommand As String, _
ByVal lpstrReturnString As String, ByVal uReturnLength As Long, ByVal hWndCallback As Long) As Long

Function vbmciSendString(ByVal Command As String, ByVal hWnd As Long) As String
    Dim Buffer As String
    Dim dwRet As Long

    Buffer = Space$(100) ' Create a buffer
    dwRet = mciSendString(Command, ByVal Buffer, Len(Buffer), hWnd)
    vbmciSendString = Buffer
End Function

Private Sub cmdOpen_Click()
  ' Pass 0 or Me.hWnd to 2nd parameter
  Call vbmciSendString("set cdaudio door open", 0)
End Sub

Private Sub cmdClose_Click()
  Call vbmciSendString("set cdaudio door closed", 0)
End Sub

latin_man,

  Did my comment suit your requirement? The code:
  Call vbmciSendString("set cdaudio door open", 0)
is to open the cd door (no matter with or without cd inside).
