How to Detect cf4 leak pointer cost

Jul 05, 2007 · Detecting Memory Leaks. Memory leaks can occur either in the stack, unmanaged heap, or the managed heap. There are many ways to find out that memory is leaking, like memory increasing in the Task Manager. Before starting to correct the memory problem, you need to determine the kind of memory which is leaking.
