Private Sub Command1_Click()
    Dim ShellApp, oPanel, FolderItem1, FolderItem2, oItem
    Set ShellApp = CreateObject("Shell.Application")
    Set oPanel = ShellApp.NameSpace(0)
    Set FolderItem2 = Nothing
    For Each FolderItem1 In oPanel.Items
      If FolderItem1.Name = "我的电脑" Then
        Set FolderItem2 = FolderItem1.Getfolder: Exit For
      End If
        Debug.Print FolderItem1.Name
    Next
    If FolderItem2 Is Nothing Then
      MsgBox "找不到项目！"
      Exit Sub
    End If
    Set oItem = Nothing
    For Each oItem In FolderItem2.Items
        Debug.Print oItem.Name
    Next
End Sub

输出结果如下：
