getting drive letters

How does one obtain the CD Drive letter of a user's machine?

What are the commands for accessing the Registry? Are these done only with WinAPI?

Thanks.

Try something like this:

Option Explicit
Private Declare Function GetLogicalDriveStrings Lib "kernel32" Alias "GetLogicalDriveStringsA" (ByVal nBufferLength As Long, ByVal lpBuffer As String) As Long

Private Sub Form_Load()
    Dim lngRet As Long
    Dim strBuffer As String
    Dim intPost As Integer
    Dim strDrive As String
    
    strBuffer = Space(255)
    lngRet = GetLogicalDriveStrings(Len(strBuffer), strBuffer)
    
    intPost = InStr(strBuffer, vbNullChar)
    strDrive = Left(strBuffer, intPost - 1)
    List1.AddItem strDrive
    
    Do Until intPost = 0
        strDrive = Mid(strBuffer, intPost + 1, 3)
        List1.AddItem strDrive
        intPost = InStr(intPost + 1, strBuffer, vbNullChar)
    Loop
End Sub
