WIN32 Edit box avec le style ES_NUMBER

J'ai fait un petit truc à la va vite, semble aller.
Me suis contenté de l'event killfocus, tu adapteras.

Une dialog avec 2 EDIT en ES_NUMBER :

WNDPROC OldProcEdNum;

void FrmtEditNbr(HWND hed)
{
  char buf[20], res[20], *c, *d, a;
  DWORD len;
  len = GetWindowText(hed, buf, 19);
  if(0 >= (long) len) return;
  c = buf;
  d = buf;
  while(a = *c) {
    c++;
    if(a != 32) *d++ = a;
  }
  *d = 0;
  len = d - buf;
  c = buf;
  d = res;
  if(len < 4) {
    while(*d = *c) {c++; d++;}
    goto dispRES;
  }
  len %= 3;
  if(len) {
    do {
      *d++ = *c++;
    } while(--len);
    *d++ = 32;
  }
  while(*d++ = *c++) {
    if(++len == 3) {
      *d++ = 32;
      len = 0;
    }
  }
  *(d - 2) = 0;
dispRES: SetWindowText(hed, res);
}

LRESULT CALLBACK EdProcNbr(HWND hwnd, UINT mssg, WPARAM wParam, LPARAM lParam)
{
  if(mssg == WM_PASTE) return 0;
  if(mssg == WM_KILLFOCUS) FrmtEditNbr(hwnd);
  return CallWindowProc(OldProcEdNum, hwnd, mssg, wParam, lParam);
}

void onInitDlg(HWND hdlg)
{
  HWND hctrl;
  SetClassLongPtr(hdlg, GCLP_HICON, (long)LoadIcon(0, IDI_APPLICATION));
  hctrl = GetDlgItem(hdlg, IDED_NBR1);
  SendMessage(hctrl, EM_LIMITTEXT, 13, 0);
  OldProcEdNum = (WNDPROC) SetWindowLong(hctrl, GWL_WNDPROC, (long) EdProcNbr);
  hctrl = GetDlgItem(hdlg, IDED_NBR2);
  SendMessage(hctrl, EM_LIMITTEXT, 13, 0);
  SetWindowLong(hctrl, GWL_WNDPROC, (long) EdProcNbr);
}
