I assume you mean for Win95 or NT.

This function returns the CDROM drive letter, or "" if none found:

Private Declare Function GetDriveType Lib "kernel32" Alias _
     "GetDriveTypeA" (ByVal sDrive As String) As Long
Private Const DRIVE_CDROM = 5

Public Function GetCDRomDrive() As String
 Dim i As Integer
 Dim sDrive As String
 GetCDRomDrive = ""      ' in case none found
 For i = 0 To 25
  sDrive = Chr$(i + 64)
  If GetDriveType(sDrive & ":\") = DRIVE_CDROM Then
   GetCDRomDrive = sDrive
   Exit For
  End If
 Next
End Function

Hope this helps, good luck!
