Hi Chris & Gordon,i did not know visual studio has an ability like that. i believe i don't know how to use visual studio.. i realized that there are many features that i did not know especially about these breakpoints.
Hi Jean-Sebastian, thank you for your answer.. i will search the previous posts of you in the archives.. it will be really useful for me because even if i use ref_ptr all the time, i have memory leaks and i can't find them.. it will be useful for me... thanks...
