MFC in socket programming, under the unicode data is received garbled, how to solve-CodePudding

In unicode, consult everybody, fairy,

How hair is how close, general network transmission in utf-8, internationally

how to use utf-8, just learning is not very will

Receiving and sending to the===="" "

Receiving part
Char szTemp [200].
Int n=Receive (szTemp, 200);
SzTemp [n]=0;

CStringA szBuf (szTemp);
Cstrings sTemp (szBuf);

Send some
The UpdateData ();

M_ListWords. AddString (_T (" send: ") + m_sWords);

CodePudding user response:

The sending part also use char * bai, just to guarantee the type consistent character set on both ends

CodePudding user response:

At the same time use WCHAR or CHAR
Use TCHAR, send length * sizeof (TCHAR)

CodePudding user response:

With a char array to receive, then char [] to cstrings

CodePudding user response:

If the client and the server is written, all with the same coding formats,
If the service side live client is bill writing, use utf-8.
Conversion method is as follows:

Would be * UTF8ToUnicode (const char * STR)
{
Int textlen=0;
The result would be *;
Textlen=MultiByteToWideChar (CP_UTF8, 0, STR, 1, NULL, 0).
Result=(*) would be malloc sizeof ((textlen + 1) * (would));
Memset (result, 0, sizeof (textlen + 1) * (would));
MultiByteToWideChar (CP_UTF8, 0, STR, 1, (LPWSTR) result, textlen);
Return the result.
