You can pass it with the dwStyle parameter to Create()/CreateEx() or set it in the resource editor
properties if it's a control on a dialog resource.

On WM_LBUTTONDOWN
   Capture the mouse (::SetCapture())
   Create a timer for the desired interval of increments (::SetTimer())
On WM_TIMER   
   Increment displayed field
   Call ::InvalidateRect(hWnd, NULL, bErase) on displayed field control
   Call ::UpdateWindow(hWnd) on displayed field control
On WM_LBUTTONUP
   Kill the timer (::KillTimer())
   Release the mouse (::ReleaseCapture())
