Hi,
I need to convert a CString to a wstring. Actual I do it while initialize the wstring (std::wstring path(sTempBuffer);) , but now I need to do it in a function. So how to convert a CString to a allway initialized wstring?

If you have UNICODE set, just use

CString test;
wstring wstr = (LPCTSTR) test;

there is a wstring constructor that accepts 'const char *'
CString is equivalent to LPCTSTR, which is the same as 'const char *'

so, you should be able to use

CString a = "test"';
std::wstring st(a);

On, and if it is an ANSI CString, make that

#include <ios>
using namespace std;

CString test;
string tmp = (LPCTSTR) test;
wstring wstr = widen(tmp.begin(),tmp.end());
