推荐答案

当任何事件触发你的代码时，我想你要问的是做一些像

When whatever event triggers your code, I think what you are asking is to do something like

if (this.WindowState == FormWindowState.Minimized) this.WindowState = FormWindowState.Maximized;

因此，如果你的窗口被最小化，当定时器事件触发时，你的表格将最大化。



我会想象你检查计时器被触发的日期和时间，然后显示表格，如果日期是正确的（而不是为每个你想要提醒的日期安排一个计时器），但你说你是一个新手 - 所以去你喜欢的任何东西并从那里成长。



timer.Stop将停止你的计时器。

So if your window is minimised, when the timer event triggers, your form will be maximised.

I would imagine you check for the date and time when the timer is triggered, then show the form if the date is the right one (rather than having a timer for each date you want to be reminded of) but you say you are a novice - so go for whatever you are comfortable with and grow from there.

timer.Stop will stop your timer.

计时器？！您想让您的应用程序运行多年吗？ :-)



你宁愿需要一些服务来创建一个报告发送你需要的东西。当然，您可以开发适当的Windows服务。当您注销时，只有一项服务会继续工作，即使您重新启动系统，它也会启动，您使用启动模式自动（ http://msdn.microsoft.com/en-us/library/windows/desktop/aa384896%28v=vs.85%29 .aspx [ ^ ]。



但Windows已经提供了为此类设计的服务。它已与Windows捆绑并启用;你可以在不同的层面上使用它。它被称为Window Task Scheduler，请参阅 http://en.wikipedia.org/wiki/Windows_Task_Scheduler [ ^ ]。



首先，您可以使用命令行实用程序AT.EXE或CSHTASKS.EXE（替换AT.EXE）来安排事件，请参阅：

http://en.wikipedia.org/wiki/At_%28Windows%29 [ ^ ]，

http://en.wikipedia.org/wiki/Schtasks [ ^ ]，

http://technet.microsoft .com / zh-cn / library / bb490866.aspx [ ^ ]，

http://msdn.microsoft.com/en-us/library/windows/desktop/bb736357%28v=vs.85%29 .aspx [ ^ ]。



您还可以使用Window Task Scheduler API，请参阅：

http://msdn.microsoft.com/en-我们/ library / windows / desktop / aa383614％28v = vs.85％29.aspx [ ^ ]，

http://msdn.microsoft.com/en-us/library/windows/desktop/aa383608%28v= vs.85％29.aspx [ ^ ] 。



要了解如何在.NET中使用它，请参阅此CodeProject文章：用于.NET的新任务计划程序类库 [ ^ ]。

Timer?! Do you want to keep your application running for years? :-)

You would rather need some service which creates a report sends what you need. Of course, you can develop appropriate Windows Service. Only a service will keep working when you log out, and even if you restart the system, it will be started, it you use start mode "Automatic" (http://msdn.microsoft.com/en-us/library/windows/desktop/aa384896%28v=vs.85%29.aspx[^]).

But Windows already provides the service designed for such things. It is already bundled with Windows and enabled; you can use it on different levels. It is called Window Task Scheduler, see http://en.wikipedia.org/wiki/Windows_Task_Scheduler[^].

First, you can schedule events using command-line utilities AT.EXE or CSHTASKS.EXE (which is replacing AT.EXE), see:
http://en.wikipedia.org/wiki/At_%28Windows%29[^],
http://en.wikipedia.org/wiki/Schtasks[^],
http://technet.microsoft.com/en-us/library/bb490866.aspx[^],
http://msdn.microsoft.com/en-us/library/windows/desktop/bb736357%28v=vs.85%29.aspx[^].

And you also can use Window Task Scheduler API, please see:
http://msdn.microsoft.com/en-us/library/windows/desktop/aa383614%28v=vs.85%29.aspx[^],
http://msdn.microsoft.com/en-us/library/windows/desktop/aa383608%28v=vs.85%29.aspx[^].

To see how can you use it with .NET, see this CodeProject article: A New Task Scheduler Class Library for .NET[^].

到显示屏幕的表单中心，在构造函数中的设计计时器on上将Forms StartPosition属性设置为 CenterScreen 。

To display your Form center of the screen, set the Forms StartPosition property as CenterScreen on design timer on in your constructor.
