The problem with your approach is when you have support for UNICODE. CString support both non-unicode and unicode while std::string support only non-unicode strings. Take a look at this post[^] to see how support both unicode and non-unicode strings. I also suggest you have a look at this excellent article[^] to get a better grip on all the different strings and 'conversions'.

And what's the problem? Are you doing a UNICODE build? :)

Yes i am building in UNICODE mode

Then

CString sFirstName=_T("Foo"), sLastName=_T("Goo");
CT2A sANSIFullName(sFirstName + sLastName);
std::string sResult(sANSIFullName);

:)

No need to be integralist, my friend :rolleyes: i.e. I usually don't make philosophical assumptions on the reason behind the question. If he really needs a std::string (maybe he need to call a function of a library out of his control), then the proposed code works; on the other hand, since he probably needs that, someone else already gave the right links to get more insights on using UNICODE or ANSI strings in his own project. :)

but we are not sheeps, we are thinking human being too, and answering the board also means advising well... Using CT2A() or CW2A() will potentially loose data if the OP is using "true" wide-characters (those which really need more than 1 byte to be). Using std::wstring will not though. BTW, your point about the external lib is true ;)
