How to convert BYTE to CString?

This is what I am trying to do:

struct fileData
{
      CString empNo[10];
      CString empName[27];
};

extern fileData *      m_fileData;
BYTE buffer[44];
DWORD dwRead;
do
      {
            i = 0;
            dwRead = myFile.Read(buffer, 44);
            m_fileData[i].empNo = buffer[10]; // This doesn't work, since assigning to a CSTring
            i++;
      }
      while (dwRead > 0);

How do I assign the byte values to my string? Any help would would be appreciated

Thanks.
