Bio 2.1.7

Bio

Full control of input on any level.

✅ Why choose Bio?

Bio allows monitoring keyboard input on any level of abstraction. It provides an easy-to-use wrapper for the native Win32 low-level keyboard hook as well as the class for working with detected input in a sophisticated way with a rich set of information about each input event.

🔩 Usage

Low-level Hook

using Bio;

using var hook = new KeyboardHook();
hook.Set();
hook.KeyDown += Hook_HandleLowLevelInputMessage;
hook.KeyUp += Hook_HandleLowLevelInputMessage;
hook.Mute();
hook.Unmute();

void Hook_HandleLowLevelInputMessage(object? sender, KeyboardInputMessage e)
{
    var wm = e.WM;
    var lowLevelKeyInfo = e.KBDLLHOOKSTRUCT;
}

High-level Input Detector

using Bio;
using Bio.Win32;

using var keySpy = new KeySpy();
keySpy.Activate();
keySpy.InputDetected += KeySpy_HandleHighLevelInputEvent;
keySpy.Mute();
keySpy.Unmute();

void KeySpy_HandleHighLevelInputEvent(object? sender, KeyInfo e)
{
    // KeyInfo is basically an advanced version of ConsoleKeyInfo that supports all keys and can differentiate between left and right modifier keys.
    VK vkCode = e.VK;
    char keyChar = e.KeyChar;
    ConsoleKey consoleKey = e.ConsoleKey;
    ModifierKeys modifierKeys = e.ModifierKeys;
}

Input Synthesizer

using Bio;
using Bio.Win32;

KeyboardInput.SynthesizePress(VK.LSHIFT, VK.KEY_A);
KeyboardInput.Synthesize(WM.KEYDOWN, VK.KEY_0);
KeyboardInput.Synthesize(WM.KEYUP, VK.KEY_0);
