TWebBrowser 屏蔽右键菜单

//Here's the code to disable the context menu (the one a user gets when it right-clicks inside a TWebBrowser) for TWebBrowser in a Delphi application:

function MouseProc(nCode: Integer; wParam, lParam: Longint): LongInt; stdcall;

var

   classbuf: array[0..255] of Char;

const

   ie = 'Internet Explorer_Server';

begin

   case nCode < 0 of

     True:

       Result := CallNextHookEx(MouseHook, nCode, wParam, lParam) ;

     False:

       case wParam of

       WM_RBUTTONDOWN, WM_RBUTTONUP:

       begin

         GetClassName(PMOUSEHOOKSTRUCT(lParam)^.HWND, classbuf, SizeOf(classbuf)) ;

         if lstrcmp(@classbuf[0], @ie[1]) = 0 then

           Result := HC_SKIP

         else

           Result := CallNextHookEx(MouseHook, nCode, wParam, lParam) ;

       end

       else

       begin

         Result := CallNextHookEx(MouseHook, nCode, wParam, lParam) ;

       end;

     end; //case wParam

   end; //case nCode

end; (*MouseProc*)

//Form OnCreate

procedure TWebBrowserForm.FormCreate(Sender: TObject) ;

begin

   MouseHook := SetWindowsHookEx(WH_MOUSE, MouseProc, 0, GetCurrentThreadId()) ;

end;

//Form OnDestroy

procedure TWebBrowserForm.FormDestroy(Sender: TObject) ;

begin

   if MouseHook <> 0 then UnHookWindowsHookEx(MouseHook) ;

end;
