I also need to replace any 0x00 (NULL) chars with 0x01 when copying to the
CString
Is this possible ?

Then ensure you build for non-Unicode (ANSI/MBCS) and just use
CString.

Are you sure you really want this to be a string?

You might be best doing what Tom suggests and handle each character
individually in a loop.

If you are building a Unicode app, you can't use CStringA.

One solution is to abandon a 12-year old and seriously out-of-date compiler and MFC.

If you have an ANSI NUL-terminated string (no embedded NUL characters, 8-bit character
set) the solution is

CByteArray buffer;
....set bytes in CByteArray
CString result;
LPWSTR p = T2CW(buffer.GetData());
result = p;
return result;

Read my essay on my MVP Tips site on CString techniques.
