How do I store a list of names into a vector of CStrings?
Hi,
I've got a list of student names in C:\students.txt. It looks like this:
Adam
Zach
Caroline
Dave
etc.
I would like to store the names in a vector of CStrings. Can someone show me how to do this? Thanks.

MFC has a collection class - CStringArray, specifically for storing numbers of CString objects. That could be an alternative if you were interested.

normally you wouldn't mix MFC collection classes with STL objects. so i would suggest to using std::ifstream, std::getline, std::string and std::vector.
if you finally need to make a CString from a std::string it is simply like CString(stdstr.c_str()).

ok i think sara pointed out something i didn't think, to not mix MFC and STL. so, instead of using CString how can i accomplish what i want using only STL?
i'm familiar with vector and string...can you show me how to do the read/input part with ifstream and getline?

Well, IMO there's no problem with and nothing against mixing MFC and STL. If I i.e. implement a dialog application using MFC since it's easy to fast write dialog applications with MFC there's no reason not to use STL classes only because both MFC and STL have their own string and file classes.
So IMO it's a matter of taste and habits. I for myself use that class which best fits my current needs. But on the other hand I think if there's no real reason to prefer one of these one should choose MFC or STL in a consistent way since this can improve readability.
Anyhow, that's just my opinion ...

i don't mix these classes cause they have different concepts and interfaces. you necessarily will need to convert between equivalent classes what in my opinion is unnecessary and against object-orientation approach where each object has one class and not more.
