Repeater
等控件.
绑定数据源后,在ItemTemplate添加label,
设定label的Text为某列的值.
不懂可以加我QQ问.注明"dotnet"
比如说这样添加的计时器:
Dim Timer1 As New Timer
你要在合适的地方开始,比如窗体Load事件中,这样:
Timer1.Interval = 1000 '单位毫秒,1000毫秒=1秒
Timer1.Enabled = True '启用计时器
然后在代码窗口上方下拉列表里选择Timer1的Tick事件,自动添加代码:
Private Sub Timer1_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles Timer1.Tick
End Sub
这是计时器触发的事件,每秒触发一次,在这里面输入循环判断是否有日程即可。提示:你可以用Now对象获取当前的日期和时间。
