Below is a simplified version of what I use in my tracing and error
handling.
It is used to build a message that includes information of both the stack
frame and
a message string/ID/severity

So, to answer your question, you can get information of the stack at any
time (and not only in case of exception handling)

If you want the information to be available in Release mode, you have to go
under
project property -> configuration property -> build (Release) and set
Generate Debug information to True.
