Keyboard

NuGet build

A library that uses the Windows low-level keyboard hook (WH_KEYBOARD_LL) to raise an event when a key is pressed, with COM support.

Targets .NET Framework 4.6.2+ and .NET 8 (net8.0-windows).

Usage

Install the package, then use the namespace:

dotnet add package EzeIO.Keylogger

using Eze.IO.Workspace;

Subscribe to key presses

static void Main(string[] args)
{
    DetectKey.OnKeyPressed += OnKeyPress_Handled;
}

static void OnKeyPress_Handled(LoggedKeys keys)
{
    VirtualKeys k = keys.Key;
    if (k == VirtualKeys.Enter)
    {
        // User pressed the 'Enter' key
    }
}

Adding the first handler installs the hook; removing the last handler (-=) uninstalls it. DetectKey.IsDetecting reports whether the hook is currently installed.

LoggedKeys exposes the pressed key as a VirtualKeys value (Key) and its name (KeyName).

COM

DetectKeyFactory (ProgId Eze.IO.Workspace.DetectKeyFactory) exposes the same event to COM clients such as VBScript or VBA, once the .NET Framework build is registered with regasm /codebase Keyboard.dll. Set Detect to true to start raising OnKeyPressed.

Building

dotnet build Keylogger.sln
dotnet pack src/Keyboard.csproj -c Release -o artifacts

The hook is a Windows API and runs on Windows only.
