GlobalMouseHook hook = new GlobalMouseHook();
hook.StatusChanged += OnStatusChanged;
hook.Start();

private void OnStatusChanged(sender s, MouseHookEventArgs e)
{
    // X Position = e.X
    // Y Possition = e.Y

    if (e.MessageType == MouseHookMessageType.MouseMove)
    {
        // Do Something

        DispatcherQueue.TryEnqueue(() =>
        {
            // Update UI Here
        });
    }

    if (e.MessageType == MouseHookMessageType.LeftButtonDown)
    {
        // Do Something
    }
}

Since the GlobalMouseHook operates on a different thread, you’ll need to update the UI in the StatusChanged event via a DispatcherQueue. Failing to do so will result in an exception.

Example with HookLevel

You can restrict the hook to your application window by specifying the TargetWindowHandle and Hook Level.

GlobalMouseHook hook = new GlobalMouseHook();
hook.TargetWindowHandle = myWindowHwnd;
hook.Level = HookLevel.Application;
