Can VBA issue a command to eject a CD?
 

I have a VBA program that reads a file created from a DVD/CD. I then by
hand eject the disc. Can VBA issue a command to eject the disc?

Can VBA issue a command to eject a CD?
 

Try this:

Option Explicit
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

Sub OpenCDDrive()

mciSendString "Set CDAudio Door Open", 0&, 0, 0

End Sub


Sub CloseCDDrive()

mciSendString "Set CDAudio Door Closed", 0&, 0, 0

End Sub

Where are you setting which drive to open/close?

This does the default audio drive.
You can specify the drive letter like this:

Option Explicit
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

Sub OpenCDDrive(Optional strDriveLetter As String)

If Len(strDriveLetter) = 0 Then
mciSendString "Set CDAudio Door Open", 0&, 0, 0
Else
mciSendString "open " & strDriveLetter & _
": type CDAudio alias drive" & strDriveLetter, 0&, 0, 0
mciSendString "set drive" & strDriveLetter & " door open", 0&, 0, 0
End If

End Sub

Sub CloseCDDrive(Optional strDriveLetter As String)

If Len(strDriveLetter) = 0 Then
mciSendString "Set CDAudio Door Closed", 0&, 0, 0
Else
mciSendString "open " & strDriveLetter & _
": type CDAudio alias drive" & strDriveLetter, 0&, 0, 0
mciSendString "set drive" & strDriveLetter & " door closed", 0&, 0, 0
End If

End Sub


Sub test()

OpenCDDrive "D"

End Sub

You can specify the drive letter like this:

Thanks. It works like a charm. I'm not sure what is considered the default.
One reads CDs/DVDs and is called "J". The other read/writes CDs/DVDs and is
called "D". I would consider the one that reads only the default.

As I've added hard drives the letters have become scrambled and I haven't
bothered to change them.

You probably won't need it, but there are lots of other
commands you can pass to this API.
