Re: How do controls get connected to variables in a CFormView?
The controls are associated with variables by DDX_Control calls in
DoDataExchange of your view class. These calls are added automatically
by the wizard if you add the control variables this way: right-click on
the control in the dialog template, select Add Variable.
You can add the same calls by hand once you see what the wizard does for
one of them.

Thank you for your reply. As near as I can tell, the code for the two
classes is the same. When does DDX_Control() first get called?
Should my variable be associated with a window by the time
OnInitialUpdate() gets called?
// TODO: Add your specialized code here and/or call the base class
The call to CView::OnInitialUpdate() causes the initial DDX_Control()
calls. So control variables first become ready to use at the TODO.
