cd tray insert notification

Are there any way to know if there is a disc in the cd/dvd-player without searching for any files? Is there a flag set somewhere in windows when a disc is inserted?

VB Code:

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
 
Private Function IsCDInDrive(ByVal strCDDriveLetter As String) As Boolean
   Dim strStatus As String * 128
   'open the device
   mciSendString "open " & strCDDriveLetter & ": type cdaudio alias cddrive wait", vbNullString, 0, 0
   'see if there's something in the drive
   mciSendString "status cddrive media present", strStatus, Len(strStatus), 0
   'close the device
   mciSendString "close cddrive", vbNullString, 0, 0
   'the string will contain "true" or "false" which can be easily converted
   IsCDInDrive = CBool(Left$(strStatus, InStr(strStatus, vbNullChar) - 1))
End Function

or u can use FSO

VB Code:

Private Sub Command1_Click()
    Dim fso As New FileSystemObject
    Dim drv As Drive
    Set drv = fso.GetDrive("A:")
    If drv.IsReady Then
        MsgBox "drive is ready"
    Else
        MsgBox "drive not ready"
    End If
End Sub

Thanks! Works great. :-)
