Добавляем прогресс бар в иконку программы C#

Всем привет. Сегодня мы будем делать прогресс бар для иконки вашей программы, находящейся в "таск баре":


Нажимаем Проект -> Добавить класс


Назовем его TaskbarProgress.cs

Удаляем всё из него и вставляем этот код:

using System;
using System.Runtime.InteropServices;

public static class TaskbarProgress
{
public enum TaskbarStates
{
NoProgress = 0,
Indeterminate = 0x1,
Normal = 0x2,
Error = 0x4,
Paused = 0x8
}

[ComImportAttribute()]
[GuidAttribute("ea1afb91-9e28-4b86-90e9-9e9f8a5eefaf")]
[InterfaceTypeAttribute(ComInterfaceType.InterfaceIsIUnknown)]
private interface ITaskbarList3
{
// ITaskbarList
[PreserveSig]
void HrInit();
[PreserveSig]
void AddTab(IntPtr hwnd);
[PreserveSig]
void DeleteTab(IntPtr hwnd);
[PreserveSig]
void ActivateTab(IntPtr hwnd);
[PreserveSig]
void SetActiveAlt(IntPtr hwnd);

// ITaskbarList2
[PreserveSig]
void MarkFullscreenWindow(IntPtr hwnd, [MarshalAs(UnmanagedType.Bool)] bool fFullscreen);

// ITaskbarList3
[PreserveSig]
void SetProgressValue(IntPtr hwnd, UInt64 ullCompleted, UInt64 ullTotal);
[PreserveSig]
void SetProgressState(IntPtr hwnd, TaskbarStates state);
}

[GuidAttribute("56FDF344-FD6D-11d0-958A-006097C9A090")]
[ClassInterfaceAttribute(ClassInterfaceType.None)]
[ComImportAttribute()]
private class TaskbarInstance
{
}

private static ITaskbarList3 taskbarInstance = (ITaskbarList3)new TaskbarInstance();
private static bool taskbarSupported = Environment.OSVersion.Version >= new Version(6, 1);

public static void SetState(IntPtr windowHandle, TaskbarStates taskbarState)
{
if (taskbarSupported) taskbarInstance.SetProgressState(windowHandle, taskbarState);
}

public static void SetValue(IntPtr windowHandle, double progressValue, double progressMax)
{
if (taskbarSupported) taskbarInstance.SetProgressValue(windowHandle, (ulong)progressValue, (ulong)progressMax);
}
}

Код

using System;

using System.Runtime.InteropServices;



public static class TaskbarProgress

{

    public enum TaskbarStates

    {

        NoProgress = 0,

        Indeterminate = 0x1,

        Normal = 0x2,

        Error = 0x4,

        Paused = 0x8

    }



    [ComImportAttribute()]

    [GuidAttribute("ea1afb91-9e28-4b86-90e9-9e9f8a5eefaf")]

    [InterfaceTypeAttribute(ComInterfaceType.InterfaceIsIUnknown)]

        [PreserveSig]

        // ITaskbarList3

        [PreserveSig]

        void SetProgressValue(IntPtr hwnd, UInt64 ullCompleted, UInt64 ullTotal);

        [PreserveSig]

        void SetProgressState(IntPtr hwnd, TaskbarStates state);

    }



    [GuidAttribute("56FDF344-FD6D-11d0-958A-006097C9A090")]

    [ClassInterfaceAttribute(ClassInterfaceType.None)]

    [ComImportAttribute()]

    private class TaskbarInstance

    {

    }



    private static ITaskbarList3 taskbarInstance = (ITaskbarList3)new TaskbarInstance();

    private static bool taskbarSupported = Environment.OSVersion.Version >= new Version(6, 1);



    public static void SetState(IntPtr windowHandle, TaskbarStates taskbarState)

    {

        if (taskbarSupported) taskbarInstance.SetProgressState(windowHandle, taskbarState);

    }



    public static void SetValue(IntPtr windowHandle, double progressValue, double progressMax)

    {

        if (taskbarSupported) taskbarInstance.SetProgressValue(windowHandle, (ulong)progressValue, (ulong)progressMax);

    }

}

Класс готов! Переходим к реализации.

Переходим в тик вашего таймера для обновления статистики и вписываем:

TaskbarProgress.SetValue(this.Handle, count_checked, count_lines);

Код

TaskbarProgress.SetValue(this.Handle, count_checked, count_lines);

count_checked - переменная, отвечающая за количество проверенных строк
count_lines - переменная, отвечающая за общее количество строк

Для теста можно вписать

TaskbarProgress.SetValue(this.Handle, 70, 100);

Код

TaskbarProgress.SetValue(this.Handle, 70, 100);
