Reading Binary files

[BoudewijnEctor]

Hi, I need to build an app to open some kind of file (it kan be any kind: .exe .html .txt .hex --> really everything) as a binary (or hexadecimal file), after that I need to convert this file to a hexadecimal file with checksums. I know how to do the last thing, but I could use some help in opening files as binaries!

If you are using MFC:

//Open a binary file called: "somefile.ext"
CFile MyFile;         // file variable
unsigned char nByte;  // binary buffer

if( MyFile.Open(TEXT("somefile.txt"), CFile::modeRead | CFile::shareDenyNone | CFile::typeBinary) )
{
  // read data and print to output
  while(MyFile.Read(&nByte,1))
    std::cout<
