Re: proper way to close a socket?

I have a problem with CAsynsocket. I can connect to a remote socket. When I
want to close the connection, I just delete the socket object (which closes
the connection) and have no problems.

But if I've started to connect to a remote socket that doesn't exist (or
doesn't accept), and I delete the local socket object while waiting for
the connection, I sometimes get an assert in CAsyncSocket::DoCallBack().
See below. Actually, it's not in the middle of an Accept call because I
test with an address and port that I know doesn't exist.

Any idea how I should be doing this so as not to crash my program?

Thanks,

Bill

void PASCAL CAsyncSocket::DoCallBack(WPARAM wParam, LPARAM lParam)
{
if (wParam == 0 && lParam == 0)
 return;

// Has the socket be closed?
CAsyncSocket* pSocket = CAsyncSocket::LookupHandle((SOCKET)wParam, TRUE);

// If yes ignore message
if (pSocket != NULL)
 return;

pSocket = CAsyncSocket::LookupHandle((SOCKET)wParam, FALSE);
if (pSocket == NULL)
{
 // Must be in the middle of an Accept call
 pSocket = CAsyncSocket::LookupHandle(INVALID_SOCKET, FALSE);
 ASSERT(pSocket != NULL);
<-------------------------------------------------asserts here sometimes
but not always.
 pSocket->m_hSocket = (SOCKET)wParam;
 CAsyncSocket::DetachHandle(INVALID_SOCKET, FALSE);
 CAsyncSocket::AttachHandle(pSocket->m_hSocket, pSocket, FALSE);
