C++ convert from string to LPCWSTR As you know, std::string is char* type, while LPCWSTR ,LPWSTRor CString is
C++ convert from LPCWSTR to string To convert fromLPCWSTRtostring, can split into two steps, first step convert fromCStringtowchar_t, 2nd step, convert fromwchar_ttochar*, as below code shows, //convert from CString to char* , first from CString to wchar_t then to char *wchar_twCharStri...

String is converted usingMultiByteToWideChar() If conversion failed, raise COM exception. And nowSysAllocString()is called. I hope MS coders do not use that function for their product development, otherwise we can crash almost every product they have produced according to this_com_util::ConvertSt...
