WindowsInput

Capture and Simulate Keyboard and Mouse Input

WindowsInput provides simple .NET (C#) classes to capture and simulate Keyboard and mouse input using Win32's SetWindowsHook and SendInput. All of the interop is done for you and there is a simple programming model for everything.

NuGet

Install-Package WindowsInput

Prerequisites

• Windows: .Net 4.6.1+

Samples

Run Notepad using the Keyboard...

publicasyncTaskRunNotepad(){awaitWindowsInput.Simulate.Events()//Hold Windows Key+R.ClickChord(KeyCode.LWin,KeyCode.R).Wait(1000)//Type "notepad".Click("notepad").Wait(1000)//Press Enter.Click(KeyCode.Return).Wait(1000)//Type out our message..Click("These are your orders if you choose to accept them...").Click("This message will self destruct in 5 seconds.").Wait(5000)//Hold Alt+F4.ClickChord(KeyCode.Alt,KeyCode.F4).Wait(1000)//Press Tab then Enter..Click(KeyCode.Tab,KeyCode.Return)//Do it!.Invoke();

Capture Keys from the Keyboard and disable the 'a' key:

publicstaticvoidMain(){using(varKeyboard=WindowsInput.Capture.Global.KeyboardAsync()){//Capture all events from the keyboardKeyboard.KeyEvent+=Keyboard_KeyEvent;Console.ReadLine();}}privatestaticvoidKeyboard_KeyEvent(objectsender,EventSourceEventArgs<KeyboardEvent>e){if(e.Data?.KeyDown?.Key==WindowsInput.Events.KeyCode.A||e.Data?.KeyUp?.Key==WindowsInput.Events.KeyCode.A){e.Next_Hook_Enabled=false;}}

Text Snippet Replacement

This example waits for someone to type 'aaa' (three A's in a row) and then replaces the text with 'Always Ask Albert'.

publicstaticTaskDo(){using(varKeyboard=WindowsInput.Capture.Global.KeyboardAsync()){varListener=newWindowsInput.EventSources.TextSequenceEventSource(Keyboard,newWindowsInput.Events.TextClick("aaa"));Listener.Triggered+=(x,y)=>Listener_Triggered(Keyboard,x,y);;Listener.Enabled=true;Console.WriteLine("The keyboard is now listening for sequences. Try typing 'aaa' in notepad.");Console.WriteLine("Press enter to quit...");Console.ReadLine();}returnTask.CompletedTask;}privatestaticasyncvoidListener_Triggered(IKeyboardEventSourceKeyboard,objectsender,WindowsInput.EventSources.TextSequenceEventArgse){e.Input.Next_Hook_Enabled=false;varToSend=WindowsInput.Simulate.Events();for(inti=1;i<e.Sequence.Text.Length;i++){ToSend.Click(WindowsInput.Events.KeyCode.Backspace);}ToSend.Click("Always ask albert!");//We suspend keyboard events because we don't want to accidently trigger a recursive loop if our//sending text actually had 'aaa' in it.using(Keyboard.Suspend()){awaitToSend.Invoke();}}

Trigger text on a special key combination

publicstaticTaskDo(){using(varKeyboard=WindowsInput.Capture.Global.KeyboardAsync()){varListener=newWindowsInput.EventSources.KeyChordEventSource(Keyboard,newChordClick(KeyCode.Control,KeyCode.Alt,KeyCode.Shift));Listener.Triggered+=(x,y)=>Listener_Triggered(Keyboard,x,y);Listener.Reset_On_Parent_EnabledChanged=false;Listener.Enabled=true;Console.WriteLine("The keyboard is now listening for chords. Try typing 'CONTROL+ALT+SHIFT' in notepad.");Console.WriteLine("Press enter to quit...");Console.ReadLine();}returnTask.CompletedTask;}privatestaticasyncvoidListener_Triggered(IKeyboardEventSourceKeyboard,objectsender,WindowsInput.EventSources.KeyChordEventArgse){varToSend=WindowsInput.Simulate.Events();ToSend.Click("You pressed the magic keys.");using(Keyboard.Suspend()){awaitToSend.Invoke();}}
