I mislabeled my code. This is actually the tube material
"70-30 Cu-Ni", "90-10 Cu-Ni", "Admiralty Metal", "Aluminum Brass",
"Aluminum Bronze", "Arsenical Copper", "Cold-Rolled Low Carbon Steel", "Copper Iron 194 (Olin 194)",
"Titanium Grades 1 & 2", "304 SS", "316/317 SS", "N08367 (AL6XN)",
"S43035 (TP439)", "S44660 (Sea-Cure)", "S44735 (AL29-4C)"
versus the tube gauge {12, 14, 16, 18, 20, 22, 23, 24, 25};
Which when matched up in x, y matrix returns the HEI gauge correction factor.

Problem is I can pass the VBA string to C++, but have had no success in checking it against the tube material values as shown above

Why this extra characters at the end?

...then why it is displaying extra characters when i am using ReadFile method.

Is there any problem in my code.

int main()
{
  myFile mObj;
  BYTE* hSrc = new BYTE[27];
  mObj.ReadBytes(hSrc,26);
  hSrc[26] = '\0';
  std::cout<<hSrc;
  return 0;
