A simple library to access windows input API (such as system global hooks for input recording and simulate input events) easily using .Net (C#\VB .net).
An example of a simple code that captures keyboard input globally:
private void OnFormLoad() {
// Setup keyboard hook
keyboardHook.OnKeyboardEvent += KeyboardHook_OnKeyboardEvent;
keyboardHook.Install();
}
// This method will be called whenever the user types any key
private bool KeyboardHook_OnKeyboardEvent(uint key, BaseHook.KeyState keyState)
{
// Here goes you code that analyzes what to do with the captured input
return false;
}WinputManager allows you to capture Windows common input (mouse and keyboard) easily. It works at system global level which means all of the low level input is being captured (By using the SetWindowsHookEx winapi).
It is the new library of InputManager (originally written for the commercial use of Mouse Recorder Pro).
The current version only allows setting up hooks and listening to common user input (such as mouse & keyboard). Input simulation is not yet supported.
WinputManager allows you to perform the following:
- Recording mouse & keyboard input easily.
- Consume mouse and input events you wish not to be processed by the system.
- Code base was rebuilt - which means less bugs and a more reusable code flow.
- Exceptions are thrown when hooking fails
The library comes by default with a running working code example. You can run it just as any .Net project. Running it will open up an example window showing how to work with this library.
In order to use this library in your project please change the WinputManager project Output type to Class library (right clicking on Solution Explorer > WinputManager > Properties > Output type > Class library, and then rebuild it).
Using WinputManager you can easily capture mouse and keyboard inputs such as: mouse clicks, keyboard typing, mouse movements, mouse scrolling.
In order to the user input, you need to setup hooks using:
- KeyboardHook - a class reponsible of capturing keyboard events.
- MouseHook - a class reopnsible of capturing mouse events.
Your application will be notified by listening to any event the hook will raise.
KeyboardHook will only raise OnKeyboardEvent(uint key, KeyState keyState). MouseHook have 3 different events:
- OnMouseMove(int x, int y)
- OnMouseEvent(int mouseEvent)
- OnMouseWheelEvent(int wheelValue)
All of the events should return false if the event shouldn't be consumed or true if the event will be consumed. Returning true simply means that the system will stop delivering the input to target window\application.
Here is a simple example on how to use this library:
KeyboardHook keyboardHook = new KeyboardHook();
MouseHook mouseHook = new MouseHook();
void InstallHooks() {
// Setup keyboard hook
keyboardHook.OnKeyboardEvent += KeyboardHook_OnKeyboardEvent;
keyboardHook.Install();
// Setup mouse hook
mouseHook.OnMouseEvent += MouseHook_OnMouseEvent;
mouseHook.OnMouseMove += MouseHook_OnMouseMove;
mouseHook.OnMouseWheelEvent += MouseHook_OnMouseWheelEvent;
mouseHook.Install();
}
void UninstallHooks() {
keyboardHook.Uninstall();
mouseHook.Uninstall();
}
private bool KeyboardHook_OnKeyboardEvent(uint key, BaseHook.KeyState keyState)
{
Debug.WriteLine(String.Format("{0} key was {1}",
((Keys) key).ToString(),
keyState == BaseHook.KeyState.Keydown ? "pressed" : "released"));
return false;
}
private bool MouseHook_OnMouseWheelEvent(int wheelValue)
{
Debug.WriteLine(String.Format("{0} mouse wheel value captured",
(MouseHook.MouseWheelEvents) wheelValue).ToString());
return false;
}
private bool MouseHook_OnMouseMove(int x, int y)
{
Debug.WriteLine(String.Format("Mouse moved to: {0},{1}", x, y));
return false;
}
private bool MouseHook_OnMouseEvent(int mouseEvent)
{
Debug.WriteLine(String.Format("{0} mouse event occured", (MouseHook.MouseEvents) mouseEvent));
return false;
}
