To convert CString to std::wstring:

CString hi("Hi");
std::wstring hi2(hi);

And to go the other way, use c_str():

std::wstring hi(L"Hi");
CString hi2(hi.c_str());

This should work as CString has operator LPCTSTR() defined:

CString s;
std::wstring s1 = s;

Try this:

std::wstring strString((LPCTSTR)strCString);

Why use a C cast for that? A fellow-worker of mine once was in the position that he had to find explicit casts, as some of them didn't work on the platform he needed to port a 4MLoC project to. He praised everyone who used C++' explicit casts (you can grep for them) and fought hard to ban all C-style casts, since they were so hard to find. – sbi Jan 11 '10 at 11:10

CString s = _T("Привет");
USES_CONVERSION;
std::wstring ws(A2W((LPCTSTR)s));
