C# Как сделать подсказку BalloonTool из приложения без формы

Question

Итак, я пытаюсь создать программу Simple Screenshot, и мне нужно, чтобы программа показывала подсказку BalloonTool, когда делается снимок экрана и когда программа настроена на запуск при запуске. Приведенный ниже код показывает всю мою программу, там нет ни формы, ни дизайнера. Просто программа, которая запускается из Program.cs, а не консольное приложение.

Теперь вам может не понадобиться все это, но я хочу убедиться, что я ничего не испортил в процессе, и да, мои Ресурсы найдены, и Значок установлен, я просто не понимаю, почему это не работает,

Я только что скопировал весь ваш код, есть небольшая проблема, но я не уверен, что вы скопировали ошибку вставки. Вам нужно держать HotKeyManagerPressed снаружи. У меня с этим сработало, вижу уведомление для меня это уведомление windows 10.

Answer 2

Вы не вызывали метод BalloonTip() в своем методе TakeFullScreenShotAsync().

    private static async void TakeFullScreenShotAsync()
    {
        await Task.Delay(750);//Allows task to be waited on for .75ths of a second. Time In ms.


        int width = Screen.PrimaryScreen.Bounds.Width;
        int height = Screen.PrimaryScreen.Bounds.Height;

        using (Bitmap screenshot = new Bitmap(width, height, PixelFormat.Format32bppArgb))
        {
            using (Graphics graphics = Graphics.FromImage(screenshot))
            {
                System.Drawing.Point origin = new System.Drawing.Point(0, 0);
                System.Drawing.Size screenSize = Screen.PrimaryScreen.Bounds.Size;
                //Copy Entire screen to entire bitmap.
                graphics.CopyFromScreen(origin, origin, screenSize);
            }

            //Check to see if the file exists, if it does, append.
            int append = 1;

            while (File.Exists($"Screenshot{append}.jpg"))
                append++;

            string fileName = $"Screenshot{append}.jpg";
            screenshot.Save(fileName, ImageFormat.Jpeg);

            // Call the Show Tip Message Here...
            BalloonTip();
        }
    }

Строка: hotKeyManager.Register(...) выдавала ошибку, так как у меня уже есть горячая клавиша, поэтому я заменяю ее на что-то еще, что работает для меня.
