If you are using STL::string you must do the cast explicitly by calling the c_str member function, for example: // assuming you are compiling for multi-byte (8-bit) strings STL::string s1; ... No hassle at all) Anyways I still have a few questions: 1) Ex: Code: typedef std::basic_string
If the std::string contains a string using the system default encoding (assuming windows, here), then you can find the length of the required wide character buffer and perform the transcoding using What other advantages would UNICODE have? Instead of using a std::string, use a std::wstring (also called a std::basic_string
How can I declare independence from the United States and start my own micro nation? Or if you want to do it all by hand you have to allocate the buffer by new or malloc.
