I'm from IP controls access to the IP, but always appear this problem, the project will use UNICODE programming, so I ask you a great god is there any solution to

 
//load socket character 
The UpdateData (TRUE); 
UpdateWindow (); 
WSADATA WSADATA; 
Int err; 
WVersionRequested=MAKEWORD (1, 1); 
Err=WSAStartup (wVersionRequested, & amp; WsaData); 
If (err!=0) 
{
return; 
} 
If (LOBYTE (wsaData wVersion)!=1 | | HIBYTE (wsaData wVersion)! 
=1){
WSACleanup (); 
return; 
} 
//create a socket 
SockClient=socket (AF_INET SOCK_STREAM, 0). 
If (INVALID_SOCKET==sockClient) 
{
MessageBox (_T (" socket creation failed!" )); 
return ; 
} 
SOCKADDR_IN addrSrv; 
Cstrings serv_addr. 
Unsigned char * pIP; 
DWORD dwIP; 
((CIPAddressCtrl *) GetDlgItem (IDC_IPADDRESS1)) - & gt; GetAddress (dwIP); 
PIP=(unsigned char *) & amp; DwIP; 
//type does not match the problems 
Serv_addr. The Format (L "% % u. % u. % u. U", * (pIP) + 3), * (pIP) + 2), * (pIP) + 1), * pIP); 
//addrSrv sin_addr. S_un. S_addr=inet_addr (" 172.25.11.17 ");//the server's IP 
AddrSrv. Sin_addr. S_un. S_addr=inet_addr (serv_addr. The GetBuffer (1));//conversion server IP address 
AddrSrv. Sin_family=AF_INET; 
//addrSrv sin_port=htons (11110);//the server port 
AddrSrv. Sin_port=htons (_ttoi (mID_PORT)); 
The connect (sockClient, (SOCKADDR *) & amp; AddrSrv, sizeof (SOCKADDR));//send a connection request to the server 

CodePudding user response:

If use MFC, why not use CSocket? Other associated with IP control directly linked into a dword,

CodePudding user response:

Convert unicode to char

CodePudding user response:

WCHAR turn char * *
WideCharToMultiByte ()

CodePudding user response:

I used the USES_CONVERSION;
In added T2A inet_addr function transformation, preliminary tests successfully

CodePudding user response:

Direct use CW2A API is the simplest
