CByteArray is class library of MFC.
You can use this class like as CString , CStringArray.
You can set/get some data from it by [] operator.

It's easy to use. check the website,

Hi,

I'm a complete newbie, with no formal training trying to learn from a bunch
of books. Unfortunately, there is much not in those basic books.

First, I'm programming a WIN32 app which is an add-on. I do need to include
windows.h, and it would seem this prevents me from using any MFC stuff.

Is the CByteArray class an MFC thing?

Can I do something like this:

    CByteArray mac;
    mac.SetSize(MAC_DIM);

    for( int i = 0; i < MAC_DIM; i++ )
    {
        macAddress[i] = guid.Data4[i+2];
    }

meaning access the elements with array syntax?

Finally, I'm completely lost on how to write a functinon

    void MyClass::Buffer2HexString( CByteArray& , string& );

which, will return the array of bytes as a hex string, meaning convert the
byte array to a string of hex digits that can be printed easily.

Might even be better to just return a string object, but what is really just
driving me crazy is the proper "UNICODE" aware way to do the above for a
small array of 6 bytes.
