without data loss?

Please help... urgent...

Thanx in advance.... Looking forward for the response....

Try to use a meaningful title for your posts.

BYTE is unsigned char.

The answer to this question should, IMO, depend on whether you are in an
ANSI or Unicode build. In ANSI build, I think you should (a) cast to
const char* (aka LPCSTR), and (b) use CString constructor. In Unicode
build you should (a) cast to const char*, (b) convert to wide string
using MultiByteToWideChar() or one of the A2W conversion routines, and
(c) use the CString constructor.

However, as it happens, CString has a constructor that takes a const
unsigned char and that works in either build (a bad feature, IMO), so
you can use that if you want to do the conversion using the local code page.

This sounds like a loaded question, but I'll bite (pun intended).

Assumming your working in the MCBS world and no embedded nulls in the
BYTE *str then the following should work fine.

const BYTE buffer[] = "This is my string";
const BYTE *str = &buffer[0];

CString myString( str ); // no loss of data
CString two;
two = str; // makes a copy
