ASCII and Unicode transfer

    We can use the windows API WideCharToMultiByte()transfer to each other.

    The code is as fellows:

#ifdef _UNICODE     char pstrService[HOSTNAME_SIZE];     WideCharToMultiByte(CP_ACP, 0, pstrService, -1, strServiceName, sizeof(pstrService), NULL, NULL ); #else     WCHAR pstrService[MAX_PATH] = {0};     MultiByteToWideChar(CP_ACP, 0, (LPCSTR)cstrText.GetBuffer(), -1, pstrService, sizeof(pstrService)); #endif
