globalmousekeyhook: A C# repository from froggy96

NEWS!

Added support for detection of key combinations and sequences see: Quickstart - Detecting Key Combinations and Seuqnces

What it does?

This library allows you to tap keyboard and mouse, to detect and record their activity even when an application is inactive and runs in background.

Prerequisites

Windows: .Net 4.0+

Installation and sources

  nuget install MouseKeyHook

Usage

private IKeyboardMouseEvents m_GlobalHook;

public void Subscribe()
{
    // Note: for the application hook, use the Hook.AppEvents() instead
    m_GlobalHook = Hook.GlobalEvents();

    m_GlobalHook.MouseDownExt += GlobalHookMouseDownExt;
    m_GlobalHook.KeyPress += GlobalHookKeyPress;
}

private void GlobalHookKeyPress(object sender, KeyPressEventArgs e)
{
    Console.WriteLine("KeyPress: \t{0}", e.KeyChar);
}

private void GlobalHookMouseDownExt(object sender, MouseEventExtArgs e)
{
    Console.WriteLine("MouseDown: \t{0}; \t System Timestamp: \t{1}", e.Button, e.Timestamp);

    // uncommenting the following line will suppress the middle mouse button click
    // if (e.Buttons == MouseButtons.Middle) { e.Handled = true; }
}

public void Unsubscribe()
{
    m_GlobalHook.MouseDownExt -= GlobalHookMouseDownExt;
    m_GlobalHook.KeyPress -= GlobalHookKeyPress;

    //It is recommened to dispose it
    m_GlobalHook.Dispose();
}

(also have a look at the Demo app included with the source)

How it works?

This library attaches to windows global hooks, tracks keyboard and mouse clicks and movement and raises common .NET events with KeyEventArgs and MouseEventArgs, so you can easily retrieve any information you need:

Mouse coordinates
Mouse buttons clicked
Mouse drag actions
Mouse wheel scrolls
Key presses and releases
Special key states

Additionally, there are MouseEventExtArgs and KeyEventExtArgs which provide further options:

Input suppression
Timestamp
IsMouseDown/Up
IsKeyDown/Up.
