Защита процесса от закрытия в Диспетчер Задач

Пример в консоли​

Создадим класс HwdTask:

using System;

public class HwdTask
{
static public IntPtr FindHWD(string title)
{
return DataImport.FindWindow(null, title);
}
static public IntPtr FindHWDEx(IntPtr main, IntPtr child, string title)
{
return DataImport.FindWindowEx(main, child, null, title);
}
}

Код

using System;

 

public class HwdTask

{

    static public IntPtr FindHWD(string title)

    {

        return DataImport.FindWindow(null, title);

    }

    static public IntPtr FindHWDEx(IntPtr main, IntPtr child, string title)

    {

        return DataImport.FindWindowEx(main, child, null, title);

    }

}

Создадим класс DataImport:

using System;
using System.Runtime.InteropServices;

internal class DataImport
{
[DllImport("user32.dll", SetLastError = true)]
public static extern IntPtr FindWindow(string lpClassName, string lpWindowName);
[DllImport("user32.dll", SetLastError = true, CharSet = CharSet.Unicode)]
public static extern IntPtr FindWindowEx(IntPtr parentHandle, IntPtr childAfter, string lclassName, string windowTitle);
[DllImport("user32.dll")]
public static extern IntPtr SetWindowPos(IntPtr hWnd, int hWndInsertAfter, int x, int y, int cx, int cy, int uFlags);
}

Код

using System;

using System.Runtime.InteropServices;

 

internal class DataImport

{

    [DllImport("user32.dll", SetLastError = true)]

    public static extern IntPtr FindWindow(string lpClassName, string lpWindowName);

    [DllImport("user32.dll", SetLastError = true, CharSet = CharSet.Unicode)]

    public static extern IntPtr FindWindowEx(IntPtr parentHandle, IntPtr childAfter, string lclassName, string windowTitle);

    [DllImport("user32.dll")]

    public static extern IntPtr SetWindowPos(IntPtr hWnd, int hWndInsertAfter, int x, int y, int cx, int cy, int uFlags);

}

Используем:

using System;
using System.Collections.Generic;
using System.Text;

namespace DataForceInvisible
{
class Program
{
static void Main(string[] args)
{
Console.Title = "DataForceInvisible [|=|ack]";
IntPtr task = HwdTask.FindHWD("Диспетчер задач Windows");
if (!task.Equals(IntPtr.Zero))
{
IntPtr proc = HwdTask.FindHWDEx(task, IntPtr.Zero, "Процессы");
if (!proc.Equals(IntPtr.Zero))
{
IntPtr kills = HwdTask.FindHWDEx(proc, IntPtr.Zero, "&Завершить процесс");
if (!kills.Equals(IntPtr.Zero))
DataImport.SetWindowPos(kills, 0, -1000, -1000, 300, 300, 0x44);
}
}
Console.ReadKey();
}
}
}

namespace DataForceInvisible

{

    class Program

    {

        static void Main(string[] args)
