C++ COde for GetDVDID

I found a code for managed .net developing. The job is to make a class that represent this code in C++. Features: - UnManaged C++ - Class have to work in MSVC Unicode projects - Class have to work in MSVC 2008 and above - Return value is a CString - All header and Libs have to be added / linked in header - Input is a CString with drive letter like "D:\" Code: public static string GetDVDID(string Drive) { long id = 0; int hr; object comobj = null; [login to view URL] status; [login to view URL] dvdGraph = ([login to view URL])new [login to view URL](); hr = [login to view URL](null, [login to view URL], out status); [login to view URL](hr); hr = [login to view URL](typeof([login to view URL]).GUID, out comobj); [login to view URL](hr); [login to view URL] dvdInfo = ([login to view URL])comobj; //comobj = null; [login to view URL](Drive + ":\\VIDEO_TS", out id); const int HEXADECIMAL = 16; String HexID = [login to view URL](id, HEXADECIMAL); return HexID; }
