I need to eject a specific CD-Drive using WMI if possible.
and I dont have windows media player installed so this ocx trick doesnt work.
any solutions to do this ?

(using a shellexec inside the vbs is ok but only if it works for win2k and XP )

thanks in advance

Try...


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

Public Sub SetCDState(pbState As Boolean)
    If pbState Then
        Call mciSendString("Set CDAudio Door Open", 0&, 0&, 0&)
    Else
        Call mciSendString("Set CDAudio Door Closed", 0&, 0&, 0&)
    End If
End Sub

... Just Call The Sub With True To Open And False To Close

Oh I Didn't Quite Read "specific" So I Don't Know If That Will Get The Right One. I'm Not Sure On The Functions Total Properties But You May Have To Tinker Around To Get It To Work For You.

Try the following

' Needs Windows Media Player installed

Set oWMP = CreateObject("WMPlayer.OCX.7")
Set colCDROMs = oWMP.cdromCollection

if colCDROMs.Count >= 1 then
    For i = 0 to colCDROMs.Count - 1
        colCDROMs.Item(i).Eject
    Next  ' cdrom
End If

'Alternative mathod without media player

'AS mentioned above, (using a shellexec inside the vbs is ok but only if it works for win2k and XP)
'This maybe what you are looking for.

 'Try this,


'Note: the CD drive cannot be close using the (Shell.Application) technique.

    Const ssfDRIVES = &H11  ' namespace constant (drives folder = 17)...
    Const cdromDrvLtr = "G:\"  ' specify your cd-rom drive letter...
   
      Set oSH = CreateObject("Shell.Application")
      ' open the cd-rom drawer...
      oSH.NameSpace(ssfDRIVES).ParseName(cdromDrvLtr).InvokeVerb "E&ject"
