You have multi-posted to comp.lang.c++ and alt.comp.lang.learn.c-c++ and
for all I know to more groups.

Please don't.

Re your question you can parse the filename in the code it's passed to,
that means, scanning from the right to find the rightmost delimiter such
as / or \. Standard C++ does not provide any means to get the "bare"
file name directly. And DOT NOT is OFF TOPIC in comp.lang.c++, which
deals only with the C++ language (and some general, portable libraries).

The .NET environment is also off-topic in alt.comp.lang.learn.c-c++ - but
(as you are undoubtedly aware) the question was a reasonable one, for which
portable solutions, such as the one you gave, exist.
