the code that does the send is:
TCHAR data[]="AAAAAAAA";
sock.Send(data,wcslen(data));
am I sending the half data?
The above code is wrong because it lacks "coherence" (I hope it is the right
english word...).
i.e. you are using TCHAR in the first line, so that means that you are going
to develop Unicode-aware code (because TCHAR can be expanded as char or
wchar_t).
But:
1) You don't decorate your string with _T() (i.e. should be TCHAR data[] =
_T("AAA....");)
2) You use wcslen, which is the Unicode (wchar_t) version of strlen (but
with TCHAR strings you should use _tcslen, which expands to strlen or wcslen
as TCHAR expands to char or wchar_t)
If you are sending text encoded as UTF-8 (which IMHO is the best practice,
as others already wrote), you should use char (or BYTE) as base character,
so you may consider translating your code like this:
char data[] = "...";
// ... or data from ::WideCharToMultiByte
// with CP_UTF8, to convert
// from Unicode UTF-16 (wchar_t) to UTF-8
...Send( data, strlen(data) );
(Note that you may want to send also the terminating \0, so the receiver can
understand when data ends...)
