These keys are used for moving around in documents or webpages and editing text. The functionality of these keys differs from program to program. They are labeled as F1, F2, F3, and so on, up to F12. The function keys are used to perform specific tasks.

The most frequently used control keys are Ctrl, Alt, the Windows logo key, and Esc.įunction keys. These keys are used alone or in combination with other keys to perform certain actions. These keys include the same letter, number, punctuation, and symbol keys found on a traditional typewriter.Ĭontrol keys.
The keys on your keyboard can be divided into several groups based on function: But did you know you can also use your keyboard to control your computer? Learning a few simple keyboard commands(instructions to your computer) can help you work more efficiently. Quite obviously you can programmatically reset these values.Whether you're writing a letter or calculating numerical data, your keyboard is the main way to enter information into your computer. IntLLKey = SetWindowsHookEx (WH_KEYBOARD_LL, LowLevelKeyboardProc, System. Private void Form1_Load ( object sender, EventArgs e ) Int hwnd = FindWindow ( "Shell_TrayWnd", "" ) Return CallNextHookEx ( 0, nCode, wParam, ref lParam ) Alt+Tab, Alt+Esc, Ctrl+Esc, Windows Key,īlnEat = ( (lParam. Public int LowLevelKeyboardProc ( int nCode, int wParam, ref KBDLLHOOKSTRUCT lParam ) Private static extern int ShowWindow ( int hwnd, int command ) Private static extern int FindWindow ( string className, string windowText ) Public static extern int CallNextHookEx ( int hHook, int nCode, int wParam, ref KBDLLHOOKSTRUCT lParam ) Public delegate int LowLevelKeyboardProcDelegate ( int nCode, int wParam, ref KBDLLHOOKSTRUCT lParam ) Public static extern int UnhookWindowsHookEx ( int hHook ) Public static extern int SetWindowsHookEx ( int idHook, LowLevelKeyboardProcDelegate lpfn, int hMod, int dwThreadId ) Then the context switches back to the application that generated the event. Instead, the context switches back to the process that installed the hook and it is called in its original context. However, the WH_KEYBOARD_LL hook is not injected into another process. If the input comes from a call to keybd_event, the input was “injected”.

The keyboard input can come from the local keyboard driver or from calls to the keybd_event function. The system calls this function every time a new keyboard input event is about to be posted into a thread input queue. The LowLevelKeyboardProc hook procedure is an application-defined or library-defined callback function used with the SetWindowsHookEx function.

The code snippet uses the LowLevelKeyboardProc which is: I will give you the the source of the method called hooks. I can’t name one, as I was looking into at least 15 which all held some useful peace of information. As for the rest I was reading many many articles, and they gave a lot of help.
Private void Form1_FormClosing ( object sender, FormClosingEventArgs e ) Important thing, don’t miss out this line: Let’s get down to business and start coding: If you change it’s value, the following registry entry gets created/modified: Software\Microsoft\Windows\CurrentVersion\Policies\System and the value of DisableTaskMgr gets set to 1. Select Remove Task Manager > Double-click the Remove Task Manager option. Navigate to: User Configuration > Administrative Templates > System > CTRL+ALT+DELETE Options.This is the place where you normally set the behaviour of the key combo. Open Start Menu > Run and enter gpedig.msc. Let’s see what we are about to do without programming anything. We will use C#’s Registry editing possibilities to set/change the group policy for the CTRL-ALT-DEL key sequence. CTRL-ALT-DEL combo is part of the SAS (Secure Attention Sequence) thus the solution to disable this is to write your own gina.dll ( Graphical Identification and Authentication).ĭon’t worry, I’m not looking into that as for now, I’m going to show you the work around. If you use this code it should be for your own fun or for learning purposes.Īfter doing some research on disabling keys or key combinations I found out that there are several ways of achieving the before mentioned key combos.
Before continue reading please note that this article doesn’t intend to call upon you to create nasty applications.
