Tulpep PopupNotifier 不适用于计时器 [英] Tulpep PopupNotifier not working with Timer

问题描述

using System;
using System.Data.SQLite;
using System.Drawing;
using System.Timers;
using System.Windows.Forms;
using Tulpep.NotificationWindow;   

public partial class Form1 : Form
{
    System.Timers.Timer timer = null;

    public Form1()
    {
        InitializeComponent();
    }

    private void buttonStart_Click(object sender, EventArgs e)
    {
        if (timer == null)
        {
            timer = new System.Timers.Timer();
            timer.Elapsed += new System.Timers.ElapsedEventHandler(ObjTimer_Elapsed);
            timer.Interval = 10000;
            timer.Start();
        }
    }

    private void ObjTimer_Elapsed(object sender, ElapsedEventArgs e)
    {
        try
        {
            PopupNotifier pop = new PopupNotifier();
            pop.TitleText = "Test";
            pop.ContentText = "Hello World";
            pop.Popup();

          //MessageBox.Show("");      !!!  here is problem  !!!
        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.Message);
        }
    }
}

这里我使用 Tulpep 通知来创建桌面通知.我的表单中有一个开始按钮.单击开始按钮时，计时器开始弹出桌面通知.但它仅在我不对 MessageBox.Show(""); 发表评论时才显示通知.如果我删除或评论 MessageBox.Show(""); 它不显示通知.我在这两种情况下都进行了调试，两种情况都没有错误或异常.

Here i am using Tulpep notification for create desktop notification. I have one start button in my form. When start button clicked, timer start to pop desktop notification. But it is shows notification only when i not comment on MessageBox.Show("");. and if i remove or comment MessageBox.Show(""); it is not showing notification. I debug in both case, there is no error or exception in both case.

有人知道为什么会这样吗?

Is any one have idea why is this happening?

我使用的是 .net framework 4.5.2，visual studio 2015，windows 8.

推荐答案

PopupNotifier 需要在 UI-Thread 之外调用.由于您的计时器的处理程序在不同的线程中运行，您需要调用您的表单来解决问题.

PopupNotifier needs to be called out of the UI-Thread. Since the handler of your timer runs in a different thread you need to invoke your form to solve the problem.

this.Invoke((MethodInvoker)delegate
{
    PopupNotifier pop = new PopupNotifier();
    pop.TitleText = "Test";
    pop.ContentText = "Hello World";
    pop.Popup();
});
