byte. For the kind of Unicode that Windows uses it's pretty academic as you

But how is that simpler than doing *sizeof(TCHAR)? Note that unlike your
approach, which
actually requires scanning the string, the .GetLength uses the precomputed
length and will
be faster for long strings. It seems a needlessly convoluted solution to
__inline GetByteLength(const CString &s) { return s.GetLength() *
sizeof(TCHAR); }
Note this works correctly whether the CString is in a Unicode or ANSI
build.

void classA::A(const CString &strMsg)
{
pLocal = new ClassB (PBYTE(LPCTSTR(strMsg)), strMsg.GetLength());
}
Just i case if strMsg is as below
CString strMsg = _T("HaiThere");
int nLen = strMsg.GetLength(); //This returns 8
When strMsg is unicode actually the Byte length is 16. But GetLenght()
returns 8. Inside ClassB i am just getting the length from the
constructor
and retrieving only that about of password..
For example only "H_a_i_T_" of the Msg can be used
So how do we get the whole Byte Length..
There is no method in CString class to get the byte length
CString is supposed to be used with strings of characters. That may be
single byte, multi byte or wide characters. All that really matters is the
number of characters. So there is no urget need for a function to get the
length of the string in bytes. If you need the number of bytes used, for
whatever reason, you have to write such a function yourself. To do that
independent of the character set actually used, you might try something
like
this:
size_t GetByteLength(CString const& str)
{
PCTSTR begin = str;
PCTSTR end = _tcschr(begin, 0);
return reinterpret_cast<BYTE*>(end) -
reinterpret_cast<BYTE*>(begin);
}
