I am using VC6.
Is there a way to copy a CByteArray to a CString?

Something like this:

CByteArray ba;
ba.Add('H');
ba.Add('e');
ba.Add('l');
ba.Add('l');
ba.Add('o');

CStringA str( reinterpret_cast<LPCSTR>( ba.GetData() ),
ba.GetSize() );

Does the CByteArray contain any embedded NUL characters? What is the character encoding
used in the CByteArray (ANSI, Unicode UTF-8, Unicode UTF-16?)

For example, if I have a message from an embedded controller (ANSI), then I would do

CByteArray msg;
....
msg.SetSize(SOME_VALUE_HERE);
ReadDevice(msg);
....
// I could do this

CStringA text((LPCSTR)msg.GetData());
CString result(text);
return result;


Note that this works correctly in Unicode and ANSI builds.

In the above example, the byte array is a NUL-terminated sequence of 8-bit characters.

But you need to say a *lot* more than you did about what is in the CByteArray!

Just to add to what the others have said, it might be worth it to do a small
loop (through the array) and add each character to the CString using += or
SetAt() checking for nulls in the array. I don't think there is a
restriction on the nulls nad it might goof up your string (unless that's
what you intend of course).

As I said, I am using VC6 and CStringA doesnt work
