TCHAR is just a macro that is defined to be either char* or wchar_t*, depending on whether your program is compiled with UNICODE or not. If not UNICODE then use just simple assignment to convert to std::string. If the program is UNICODE then use one of the conversion functions, such as wcstombs(). That function works ok with English language, but I don't know about other languages.
