mouse event when resizing window

Hi

I want a message box pops up after resizing window, but not during resizing it.

I tried with

Code:

---

case  WM_LBUTTONDOWN:
  message = FALSE;
  return 0;

case WM_LBUTTONUP:
  showData = TRUE;
  return 0;

/*...*/

case WM_PAINT:
  if(message)
    MessageBox(0,"the window got resized","ok",MB_OK);
 return 0;

---

but it never worked, what can I do for it, thanks!!

Whilst the user is resizing the window it is sent a stream of WM_SIZING messages. When the resizing operation is complete, it is sent a WM_SIZE message. Process these if you want to respond to resizing events.

Thanks, but it always sends a message to WM_SIZE even when I am resizing it. :(

All I want is just not updating window until I stop resizing it. any other way else?

Give WM_EXITSIZEMOVE a try.

Thanks, it seems ok, but I met some problems:

Code:

---

case WM_EXITSIZEMOVE:
      showData = TRUE;
      return 0;

case WM_PAINT:
 
        hdc = BeginPaint (hwnd, &ps) ;
        GetClientRect (hwnd, &rect) ;
      if(showData)
      {
          Ellipse(hdc, 100, 100, 109, 109);
                                   
      }
 
      showData = FALSE;

    EndPaint (hwnd, &ps) ;
                         
    return 0 ;

it still didn't show the ellipse, seems WM_PAINT message has been sent serveral times after WM_EXITSIZEMOVE, but therotically, WM_PAINT only is called once in my mind, what's wrong with it :(!!
