mouse events and system("cls") problem

ice-man6969

I've been using the following code and it works perfectly except for when I use the command "system("cls")" before using this code. How can I overcome that obstacle?
thanks in advance

The code:

HANDLE hInput;
   INPUT_RECORD ir;
   unsigned long nEvents;

       printf("Hit Escape to view other stuff...\n\n");

   hInput = GetStdHandle(STD_INPUT_HANDLE);
   while (1)
   {
       ReadConsoleInput(hInput, &ir, 1, &nEvents);
       if (ir.EventType == MOUSE_EVENT)
       {
           printf("Mouse Event: nEvents=%d x=%d y=%d button state=%ld\n",
           nEvents,
           ir.Event.MouseEvent.dwMousePosition.X,
           ir.Event.MouseEvent.dwMousePosition.Y,
           ir.Event.MouseEvent.dwButtonState);
       }
       else if (ir.EventType == KEY_EVENT)
       {
           printf("Keyboard Event: Events=%d bKeyDown=%d dwControlKeyState=%d"
               " uChar=%d wRepeatCount=%d wVirtualKeyCode=%d wVirtualScanCode=%d\n",
           nEvents, ir.Event.KeyEvent.bKeyDown, ir.Event.KeyEvent.dwControlKeyState,
           ir.Event.KeyEvent.uChar, ir.Event.KeyEvent.wRepeatCount,
           ir.Event.KeyEvent.wVirtualKeyCode, ir.Event.KeyEvent.wVirtualScanCode,
           ir.Event.MouseEvent.dwMousePosition.X,
           ir.Event.MouseEvent.dwMousePosition.Y,
           ir.Event.MouseEvent.dwButtonState);

           if (ir.Event.KeyEvent.wVirtualKeyCode == ESC)
               break;
       }
       else if (ir.EventType == FOCUS_EVENT)
       {
           printf("Focus Event: nEvents=%d bSetFocus=%d\n",
           nEvents, ir.Event.FocusEvent.bSetFocus);
       }
   }

   cout << "press a key...";
   getch();

The best solution would be, to avoid system("cls") completely

(btw, you should decide, whether you use C's printf()-Funktion or C++'s iostream's, but it's better not to mix them together)

Hm ice-man meinte ja, es mit dem system("cls") hinbekommen zu haben...

Die andere Sache mit void cls( HANDLE hConsole )
Damit komme ich nicht klar, was für ein handle soll ich denn übergeben, ich mein soll da ein "this" hin, immerhin ist es bei mir nur eine Consolenanwendung. Ich bin nicht ganz firm mit der Windowsprogrammierung...
