Using jna for branding and consumption

Question

I am making an automatic clicker that uses jna to connect global keyboard and mouse input. For the keyboard, use http://code.google.com/p/goldriver/source/browse/trunk/king/src/jnacontrib/w32keyhook/KeyHook.java?r=36 .

I was wondering if there is any possible way to use a key event so that other applications do not handle it?

Fixed with the return of the new LRESULT (1);

Now I have a problem with not continuing with the rest of the code, here is the source. My program continues to listen to keyboard input and does not even continue to show a graphical interface.

public class GUI extends javax.swing.JFrame{ ArrayList<MEvent> events; public static final int RUNNING = 0; public static final int PAUSED = 1; public static final int STOPPED = 2; public static final int LISTENING = 3; private int process = STOPPED; private String display; private JTable Events; DefaultTableModel list; Loader loader; private static MouseHook mh; static private KeyHook kh; static GUI gui; Robot robot; /** Creates new form GUI */ public GUI() { initComponents(); loader = new Loader(this); events = new ArrayList<MEvent>(); list = new DefaultTableModel(); mh = new MouseHook(this,list); mh.setMouseHook(); list.addColumn("Type"); list.addColumn("X"); list.addColumn("Y"); list.addColumn("Sleep"); try { robot = new Robot(); } catch (AWTException ex) {} displayProcess(process); Events.setModel(list); kh = new KeyHook(this); kh.run(); } public static void main(String args[]) { java.awt.EventQueue.invokeLater(new Runnable() { public void run() { gui = new GUI(); gui.setVisible(true); } }); } } public class KeyHook implements Runnable{ private static volatile boolean quit; private static HHOOK hhk; private static LowLevelKeyboardProc keyboardHook; private GUI gui; User32 lib; HMODULE hMod; public boolean isHooked = false; public KeyHook(final GUI gui) { this.gui = gui; lib = User32.INSTANCE; hMod = Kernel32.INSTANCE.GetModuleHandle(null); Native.setProtected(true); } @Override public void run() { keyboardHook = new LowLevelKeyboardProc() { public LRESULT callback(int nCode, WPARAM wParam, KBDLLHOOKSTRUCT info) { if (nCode >= 0) { switch (wParam.intValue()) { case WinUser.WM_KEYUP: switch(info.vkCode){ //F7 case 0x76: System.out.println("F7"); gui.listen(); break; //F8 case 0x77: System.out.println("F8"); gui.stopListening(); break; //F9 case 0x78: //System.out.println("F9"); //gui.start(); break; //F10 case 0x79: //gui.pause(); break; //F11 case 0x7A: //gui.stop(); break; //ESC case 0x1B: quit = true; break; } break; case WinUser.WM_KEYDOWN: break; case WinUser.WM_SYSKEYUP: break; case WinUser.WM_SYSKEYDOWN: break; } } return new LRESULT(1);//lib.CallNextHookEx(hhk, nCode, wParam, info.getPointer());// } }; hhk = lib.SetWindowsHookEx(WinUser.WH_KEYBOARD_LL, keyboardHook, hMod, 0); //noinspection ConstantConditions new Thread() { public void run() { while (!quit) { try { Thread.sleep(10); } catch (Exception e) { e.printStackTrace(); } } System.err.println("unhook and exit"); lib.UnhookWindowsHookEx(hhk); System.exit(0); } }.start(); // This bit never returns from GetMessage int result; MSG msg = new MSG(); while ((result = lib.GetMessage(msg, null, 0, 0)) != 0) { if (result == -1) { System.err.println("error in get message"); break; } else { System.err.println("got message"); lib.TranslateMessage(msg); lib.DispatchMessage(msg); } } lib.UnhookWindowsHookEx(hhk); } } 

Answer 1

Yes don't call

 return lib.CallNextHookEx(hhk, nCode, wParam, info.getPointer()); 

In the callback method ... but it's kind of an evil thing, isn't it? And if not evil, it is potentially dangerous.
