VK_F4 je virtual kod za F4.
Imam ba hook za sve poruke.
Sada kada obrađujem tu poruku ako je neki kjluč sa tastature onda mogu dobiti njegov key kode.

Code:

function MsgFilterFunc(Code: Integer; wParam, lParam: Longint): Longint;
var
  MMFHandle: THandle;
  MMFData: PMMFData;
  Kill: boolean;
begin
  Result := 0;
  MMFHandle := OpenMMF(MMFName);
  if MMFHandle <> 0 then
  begin
    MMFData := MapMMF(MMFHandle);
    if MMFData <> nil then
    begin
      if (Code < 0) or (wParam = PM_NOREMOVE) then
        {
          The CallNextHookEx function passes the hook information to the
          next hook procedure in the current hook chain.
        }
        Result := CallNextHookEx(MMFData.NextHook, Code, wParam, lParam)
      else
      begin
        Kill := False;

        with TMsg(Pointer(lParam)^) do
        begin
          // Kill Numbers
          if (wParam >= 48) and (wParam <= 57) then Kill := True;
          // Kill Tabulator
          if (wParam = VK_TAB) then Kill := True;
        end;

          //Example to disable all the start-Key combinations
        case TPMsg(lParam)^.message of
          WM_SYSCOMMAND: // The Win Start Key (or Ctrl+ESC)
            if TPMsg(lParam)^.wParam = SC_TASKLIST then Kill := True;

          WM_HOTKEY:
            case ((TPMsg(lParam)^.lParam and $00FF0000) shr 16) of
              VK_D,      // Win+D        ==> Desktop
              VK_E,      // Win+E        ==> Explorer
              VK_F,      // Win+F+(Ctrl) ==> Find:All (and Find: Computer)
              VK_M,      // Win+M        ==> Minimize all
              VK_R,      // Win+R        ==> Run program.
              VK_F1,     // Win+F1       ==> Windows Help
              VK_PAUSE:  // Win+Pause    ==> Windows system properties
                begin
                  Kill := True;
                  showmessage(IntToStr(TPMsg(lParam)^.wParam));
                end;
            end;
        end;
        if Kill then TPMsg(lParam)^.message := WM_NULL;
        Result := CallNextHookEx(MMFData.NextHook, Code, wParam, lParam)
      end;
      UnMapMMF(MMFData);
    end;
    CloseMMF(MMFHandle);
  end;
end;

Kako sada da u ovom primjeru saznam da li pritinuto Ctrl+Alt+Delete??
