using System;
using System.Collections.Generic;

using System.Data;
using System.Diagnostics;
using System.Drawing;
using System.Linq;
using System.Runtime.InteropServices;
using System.Text;

namespace Klikacz____TzPw
{

public partial class Form1 : Form
{
    \[DllImport(dllName: "User32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)\]

    public static extern void mouse\_event(int dwFlags, int dx, int dy, int cButtons, int dwExtraInfo);

    private const int LEFTUP = 0x0004;
    private const int LEFTDOWN = 0x0002;

    public Form1()
    {
        InitializeComponent();
        this.ActiveControl = button1;
        button1.Focus();
    }

    private void Click\_clock\_Tick(object sender, EventArgs e)
    {
        Random rnd = new Random();
        int maxcps = (int)Math.Round(1000.0 / (trackBar1.Value + 0 \* 0.2));
        int mincps = (int)Math.Round(1000.0 / (trackBar1.Value + 0 \* 0.4));

        try
        {
            Click\_clock.Interval = rnd.Next(mincps, maxcps);
        }

        catch
        {
            //Ignored..
        }

        bool mousdown = MouseButtons == MouseButtons.Left;
        if (mousdown)
        {
            mouse\_event(dwFlags: LEFTUP, dx: 0, dy: 0, cButtons: 0, dwExtraInfo: 0);
            Thread.Sleep(millisecondsTimeout: rnd.Next(1, 6));
            mouse\_event(dwFlags: LEFTDOWN, dx: 0, dy: 0, cButtons: 0, dwExtraInfo: 0);
        }

    }

    private void button1\_Click(object sender, EventArgs e)
    {
        if (button1.Text.Contains("Uruchom"))
        {
            Click\_clock.Start();
            button1.Text = "Wstrzymaj";
        }
        else
        {
            Click\_clock.Stop();
            button1.Text = "Uruchom";
        }
    }

    private void trackBar1\_Scroll(object sender, EventArgs e)
    {
        CPSValue.Text = "CPS = " + trackBar1.Value.ToString();
    }
}

1. you can keep things in your app running, whether or not your app is the current active application, by using a Timer, or having a some form of 'while loop. advice : don't use a 'while loop. 2) when your app is not active ... it can still get messages by using a GlobalKeyBoardHook it defines, and registers, that intercepts some keyboard combination of keys. warning: you override some other app's keyboard hooks, and you are in trouble. I believe what you probably need to use is the SystemTray app model, and CP has several articles that will show you how to use that: [^] However, if what you want is some kind of stealth monitoring app: you won't get help with that here.
