Try CreateFile and WriteFile.

string s = "file.dat";

HANDLE hFile = CreateFile(s.c_str(),       // name of the write
                   GENERIC_WRITE,          // open for writing
                   0,                      // do not share
                   NULL,                   // default security
                   CREATE_ALWAYS,          // Creates a new file, always
                   FILE_ATTRIBUTE_NORMAL,  // normal file
                   NULL);                  // no attr. template
DWORD writesBytes;
bool writeok = WriteFile(hFile, &Current_Doc, sizeof(Current_Doc), &writesBytes, NULL);

CloseHandle(hFile);
