VB如何实现一个按钮，点击按钮之后就能够浏览电脑中的文件夹，当选中文件夹之后显示该文件下的所有Excel文

VB2010的可以吗？ “能够浏览电脑中的文件夹”你指在什么 地方什么组件内浏览？”当选中文件夹之后”这里的“选中”是什么操作？ 

...............

vb6的：

Private Sub Command1_Click()

    With CommonDialog1

        .DialogTitle = "打开Ecxel文件"

        .Filter = "EXCEL文件|*.xls;*.xlsx"

    .ShowOpen

    End With

End Sub
