I need to know how to detect if the CDrom drive is open or closed, and have it return a value, so a different picture can be displayed, depending on the cdtrays status.

' Code assumes VB5
' Add to a module
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


' To check if the door is closed and close it if
' it is not already closed.
Private Sub Command2_Click()
status = mciSendString("Set CDAudio Door Closed Wait", 0&, 0, 0)

    If (status <> 0) Then
        ' Do this code if the door is closed
        ' Display Closed CD Picture
    Else
        ' Do this code if the door is not closed
        ' Display Open CD Picture
    End If
End Sub

' A statement like the following will check if the door is open
' and open it if it is not
status = mciSendString("Set CDAudio Door Open Wait", 0&, 0, 0)
