进行文件操作时，经常要用 VBA 选择目标文件夹，现提供实现代码：
1.FileDialog 属性
Sub Sample1()
With Application.FileDialog(msoFileDialogFolderPicker)
If .Show = True Then
MsgBox .SelectedItems(1)
End If
End With
End Sub
2.shell 方法
Sub Sample2()
Dim Shell, myPath
Set Shell = CreateObject("Shell.Application")
Set myPath = Shell.BrowseForFolder(&O0, "请选择文件夹", &H1 + &H10, "G:")
If Not myPath Is Nothing Then MsgBox myPath.Items.Item.Path
Set Shell = Nothing
Set myPath = Nothing
End Sub
