I have a timer that is created in a subclass of CListView :

void CResultsView::OnInitialUpdate()
{
:
SetTimer( REFRESH_VIEW_TIMER_ID, iScreenRefreshRate, NULL);
}

From elsewhere in my MFC application, I wish to stop the above timer

using KillTimer() . How can this be done? I want a pointer to the
CResultsView object, but it is declared:

protected:
CResultsView(); // protected constructor used by dynamic
creation
DECLARE_DYNCREATE(CResultsView)

glchin:

The protected constructor has protected you (pun intended) from making a
beginner mistake. To kill your timer, you must not create a new
CResultsView object; rather you should get a pointer to the existing
CResultsView object, and call some public method on it. This method
should kill the timer, using the ID that is (presumably) known to the
CResultsView object that created it.

Be sure you understand the difference between classes and objects.
