Dim lvw As WinForm.ListView = e.Form.Controls("ListView1")
Dim vr As WinForm.ListViewRow = lvw.Current '获取ListView的当前行
If vr Is Nothing Then '如果不存在当前行,也就是内有选定任何一行

Dim ps As Integer = Tables("员工").FindRow(dr)
If ps >= 0 Then

    Forms("员工信息").Open
    For Each cl As WinForm.ListViewColumn In lvw.Columns '逐列更新值
        vr(cl.Name) = r(cl.Name)
