老师你好，我想问一下我有个窗口是用于录入的，有上一页，下一页，我的效果是如果他上一页就显示上一页的跟进时间，如果是下一页就显示下一页的跟进时间，就不会一点击就一直显示在那里老师您好，这是我的代码Dim d As Date = Date.Today.adddays(val(e.Form.Controls("Label20").text))Dim dt As Date = format(d,"yyyy-MM-dd 23:59:59"
)Dim t As TimeSpan = dt - Date.Now '计算现在离今天的24时整还差多少时间e.Form.Controls("Label29").Text = "剩余" & t.Days & "天" & t.Hours & "小时" & t.Minutes & "分" & t.Seconds & "秒"
Dim Lbl As WinForm.Label = e.Form.Controls("Label29")If Lbl.ForeColor = Color.Red Then Lbl.ForeColor = Color.BlackElse Lbl.ForeColor = Color.RedEnd If
