Watching a SOCKET programming found when the server will also call the following code after closed,-CodePudding

 void CChatDlg: : ServerClose ()//server close call 
{
if (! M_ServerOnline) 
{
return; 
} 
CSocket sock. 
SOCKADDR_IN SockAddr.

SockAddr. Sin_port=htons (m_ListenPort); 
The sock. The Create (); 
The sock. Connect ((SOCKADDR *) & amp; SockAddr, sizeof (SockAddr)); 
DWORD I=GetLastError (); 
If (m_bExit) 
{
PostMessage (WM_CLOSE); 
} 
}

This is not shut down the server to create a connection and connection SOCKET

CodePudding user response:

See the IP, to create a connection within the machine,

CodePudding user response:

It is ok that this code directly away
Simply write blather, perhaps is disorderly copy paste lane
Reality in addition to the beginner, novice, who would have to write code in CSocket? Let alone write a server-side code in CSocket

CodePudding user response:

Have to get rid of what is the effect?

CodePudding user response:

The

reference 3 floor VisualEleven response:

have removed what effect?

You didn't see it CSocket is created within the function? A function which is automatically destroyed, there is a hair effect.
Remove directly, it is ok to keep global parameters of several modified

Do you take the if (m_bExit)
{
PostMessage (WM_CLOSE);
}
Also commented out?
