在c＃中显示线程内的balloontip [英] Show balloontip inside thread in c#

问题描述

我的项目有一个名为inHour的字符串设置，在主窗体中，用户可以更改该字符串，这是一种特定的小时和分钟格式：hh：mm tt。



现在，假设我已将默认小时更改为下午4:50当实时到达该字符串时（通过使用DateTime.Now.ToString（hh：mm tt）== inHour），系统托盘中会显示一个ballontip（通过使用notifyIcon）。



因此，比较时间条件位于FormLoad中启动的线程内。如果时间到达下午4:50 balloontip显示但它仍然可见，因为线程没有停止。



我尝试将int设置为0，然后将其设置为i ++，所以我用了一段时间条件，检查当int i不等于0时它将检查是否是时间显示balloontip但是如果我设置然后i为0线程将不会继续，如果我改变小时再次测试它将无法工作，因为我等于0并且没有再次设置为无限。



那么我怎样才能找到检查时间的方法，显示气球提示并重新开始所有过程？



提前谢谢，CCB

解决方案

您可以使用定时显示而不是每次都在线程中显示：

  var  icon =  new  NotifyIcon （）; 
 icon.ShowBalloonTip（ 1000 ， 气球title， 气球文字，ToolTipIcon.None）

My project has a string setting named inHour, and in the main form the user is able to change that string, which is a specific hour and minute formatted this way: hh:mm tt.

Now, let's say I have changed the default hour to 4:50 p.m. When real time reaches that string (by using DateTime.Now.ToString("hh:mm tt") == inHour), a ballontip is shown in the system tray(by using notifyIcon).

So, the comparing time condition is inside a thread that is started at the FormLoad. If time reaches 4:50 p.m. the balloontip shows but it stays visible because the thread has not stopped.

I tried declaring an int set to 0, then set it as i++, so I used a while condition, checking that while int i is not equal to 0 it will check if it is time to show the balloontip but if I set then i to 0 the thread will not continue and if I change the hour to test again it will not work because i is equal to 0 and has not set to infinite again.

So how can I find a way to check for time, show balloontip and start again all the process?

Thanks in advance , CCB

解决方案

You can use timed display instead of showing in thread every time:

var icon = new NotifyIcon();
icon.ShowBalloonTip(1000, "Balloon title", "Balloon text", ToolTipIcon.None)
