A Multiple Selection based Control Tracker Often in developing designer and CAD related applications, one needs the functionality of moving and resizing selected objects around. MFC run-time provides one class i.e. CRectTracker that does something like this, but it has several shortcomings, the most important one being that it does not have functionality for multiple object selection and resizing. This article introduces a class, CControlTracker that does much more than what CRectTracker does
