全局鉤子鎖定鍵盤(Delphi)//可以鎖所有鍵盤按鍵和任意組合鍵,但對于ALT+TAB,CTRL+ALT+DEL無效!

//DLL代碼如下

Library KillKB;

uses Wintypes, WinProcs;

Var
    oldHook: HHook;

function KBHooKProc(code: Integer; wParam: WPARAM;lParam: LPARAM):LRESULT;stdcall; export;
Begin
If code < 0 Then
   Result := CallNextHookEx( oldHook, code, wparam, lparam )
Else
   Result := 1;
end;

function DisableKeyboard: Boolean; export;
Begin
    oldHook := SetWindowsHookEx(WH_KEYBOARD,KBHooKProc,HInstance, 0 );
    DisableKeyboard := oldHook <> 0;
End;

procedure EnableKeyboard; export;

If oldHook <> 0 Then Begin
    UnhookWindowshookEx( oldHook );
    oldHook := 0;
End;
