Looked at other people's code, want to change, the old error when receiving data,
what to do?
Code:

 UINT recv_thd (LPVOID p) 
{
Int res; 
Char MSG [1024]. 
CString s; 
=(CCFileDlg *) AfxGetApp CCFileDlg * DLG () - & gt; GetMainWnd (); 
DLG - & gt; The update (" in THD "); 

While (1) 
{
If ((res=recv (sock, MSG, 1024, 0))==1) 
{
DLG - & gt; The update (" lost connection "); 
break; 
} 
The else 
{
MSG (res)='\ 0'; 
//MSG (res)=0; 
DLG - & gt; The update (" server: "+ cstrings (MSG)); 
////////////////////////////////////////////add//
Cstrings data; 
Data=https://bbs.csdn.net/topics/msg; 
Cstrings str1; 
Cstrings str2; 
Cstrings str3; 
Cstrings str4; 
Cstrings str5; 
Cstrings machine_num; 

AfxExtractSubString (machine_num, data, 0, '#'); 
AfxExtractSubString (str1, data, 1, '#'); 
AfxExtractSubString (str2, data, 2, '#'); 
AfxExtractSubString (str3, data, and 3, '#'); 
AfxExtractSubString (str4, data, 4, '#'); 
AfxExtractSubString (str5, data, 5, '#'); 
If (machine_num=="m1") 
{
DLG - & gt; M1_zhuansu=str1; 
DLG - & gt; M1_qiansheng=str2; 
DLG - & gt; M1_niandu=str3; 
DLG - & gt; M1_dingchang=str4; 
DLG - & gt; M1_chanliang=str5; 
} 
DLG - & gt; The UpdateData (false); 

} 
} 

//closesocket (sock); 
return 0; 
}

You send a custom message to the UI thread thread, in the message response function of the UI thread to break up the information, and then display in different edit box.

There must be a string split agreement...
