Comment faire pour supprimer les touches de changement de tâche (winkey, alt-tab, alt-esc, ctrl-esc) en utilisant le crochet de bas niveau du clavier dans c #

J'ai le code complet pour désactiver Touche Windows , Alt + Tabet ainsi de suite..

Et maintenant je suis en fournissant le code suivant comme référence pour les autres:

    /* Code to Disable WinKey, Alt+Tab, Ctrl+Esc Starts Here */
//Structure contain information about low-level keyboard input event 
[StructLayout(LayoutKind.Sequential)]
private struct KBDLLHOOKSTRUCT
{
public Keys key;
public int scanCode;
public int flags;
public int time;
public IntPtr extra;
}
//System level functions to be used for hook and unhook keyboard input  
private delegate IntPtr LowLevelKeyboardProc(int nCode, IntPtr wParam, IntPtr lParam);
[DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
private static extern IntPtr SetWindowsHookEx(int id, LowLevelKeyboardProc callback, IntPtr hMod, uint dwThreadId);
[DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
private static extern bool UnhookWindowsHookEx(IntPtr hook);
[DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
private static extern IntPtr CallNextHookEx(IntPtr hook, int nCode, IntPtr wp, IntPtr lp);
[DllImport("kernel32.dll", CharSet = CharSet.Auto, SetLastError = true)]
private static extern IntPtr GetModuleHandle(string name);
[DllImport("user32.dll", CharSet = CharSet.Auto)]
private static extern short GetAsyncKeyState(Keys key);
//Declaring Global objects     
private IntPtr ptrHook;
private LowLevelKeyboardProc objKeyboardProcess;
private IntPtr captureKey(int nCode, IntPtr wp, IntPtr lp)
{
if (nCode >= 0)
{
KBDLLHOOKSTRUCT objKeyInfo = (KBDLLHOOKSTRUCT)Marshal.PtrToStructure(lp, typeof(KBDLLHOOKSTRUCT));
//Disabling Windows keys 
if (objKeyInfo.key == Keys.RWin || objKeyInfo.key == Keys.LWin || objKeyInfo.key == Keys.Tab && HasAltModifier(objKeyInfo.flags) || objKeyInfo.key == Keys.Escape && (ModifierKeys & Keys.Control) == Keys.Control)     
{
return (IntPtr)1; //if 0 is returned then All the above keys will be enabled
}
}
return CallNextHookEx(ptrHook, nCode, wp, lp);
}
bool HasAltModifier(int flags)
{
return (flags & 0x20) == 0x20;
}
/* Code to Disable WinKey, Alt+Tab, Ctrl+Esc Ends Here */

À l'Intérieur de l'Form_Load();

   private void Form_Load(object sender, EventArgs e)
{
ProcessModule objCurrentModule = Process.GetCurrentProcess().MainModule;
objKeyboardProcess = new LowLevelKeyboardProc(captureKey);
ptrHook = SetWindowsHookEx(13, objKeyboardProcess, GetModuleHandle(objCurrentModule.ModuleName), 0);  
}
