通过使用process.start在vb.net中调用.exe来显示Windows通知

Question

我有一个vb.net程序，用Process.start()调用.exe关于这个.exe的简短摘要：它从WebServer下载文件并在下载开始时发送一些Windows通知..如果我刚开始我的“LiveUpdate”，这个算法工作正常.exe“文件。

这是我在vb.net代码中的调用：

Process.Start(location & "LiveUpdate.exe", "-f "settings.ini")

这是我的c＃通知方法

public void Popup(string title, string description, Icon systemIcon, ToolTipIcon icon = ToolTipIcon.Info)
        {
            var notification = new NotifyIcon()
            {
                Visible = true,
                Icon = systemIcon, //SystemIcons.Information,
                BalloonTipIcon = icon,
                BalloonTipTitle = title,
                BalloonTipText = description
            };
            Task.Run(() => OpenAndCloseNotification(notification, 2));
        }

        public void OpenAndCloseNotification(NotifyIcon notification, int secconds)
        {
            var milisecconds = secconds * 1000;
            notification.ShowBalloonTip(milisecconds);
            Thread.Sleep(milisecconds);
            notification.Dispose();
        }

好吧，vb.net不允许弹出Windows - 通知？如果您需要，我会附上更多代码，提前谢谢。

对不起，来晚了

这就是它的外观，您可以更改背景图像并删除透明胶片。如果不这样做，请选择具有普通背景的背景，因此它将该颜色设置为透明，并且仅保留中心图像的形状。

自Windows 10以来，我也遇到过许多Windows通知问题。我不知道它取决于什么，但有时是有效的，有些则不然。

你试图直接在clic的按钮事件上显示通知吗？至少那样你会检查它是否有效。

无论如何，最后我必须做的是创建我自己的通知，其中一个表单在所需时间内显示在桌面的角落。

如果您对此解决方案感兴趣，我会向您展示代码
