    <p>I have code (my c++ socket server) but I don't know How can I always open. My server will close. when It already send to client It will close itself. But I want it to wait others client and never closed. How can I do it ? Oh I use multi-threaded too.</p> <p>please,Help me.</p> <p>and here is my code</p> <pre><code>int main(void) { HANDLE hThread[3]; DWORD dwID[3]; DWORD dwRetVal = 0; hThread[0] = CreateThread(NULL,0,(LPTHREAD_START_ROUTINE)ThreadTwo,NULL,0,&amp;dwID[0]); dwRetVal = WaitForMultipleObjects(3, hThread, TRUE, INFINITE); CloseHandle(hThread[0]); return 0; } long WINAPI ThreadTwo(long lParam) { WSADATA wsaData; SOCKET ListenSocket = INVALID_SOCKET, ClientSocket = INVALID_SOCKET; struct addrinfo *result = NULL, hints; char recvbuf[DEFAULT_BUFLEN]; int iResult, iSendResult; int recvbuflen = DEFAULT_BUFLEN; iResult = WSAStartup(MAKEWORD(2,2), &amp;wsaData); if (iResult != 0) { printf("WSAStartup failed with error: %d\n", iResult); return 1; } ZeroMemory(&amp;hints, sizeof(hints)); hints.ai_family = AF_INET; hints.ai_socktype = SOCK_STREAM; hints.ai_protocol = IPPROTO_TCP; hints.ai_flags = AI_PASSIVE; iResult = getaddrinfo(NULL, DEFAULT_PORT, &amp;hints, &amp;result); if ( iResult != 0 ) { printf("getaddrinfo failed with error: %d\n", iResult); WSACleanup(); return 1; } ListenSocket = socket(result-&gt;ai_family, result-&gt;ai_socktype, result-&gt;ai_protocol); if (ListenSocket == INVALID_SOCKET) { printf("socket failed with error: %ld\n", WSAGetLastError()); freeaddrinfo(result); WSACleanup(); return 1; } iResult = bind( ListenSocket, result-&gt;ai_addr, (int)result-&gt;ai_addrlen); if (iResult == SOCKET_ERROR) { printf("bind failed with error: %d\n", WSAGetLastError()); freeaddrinfo(result); closesocket(ListenSocket); WSACleanup(); return 1; } freeaddrinfo(result); iResult = listen(ListenSocket, SOMAXCONN); if (iResult == SOCKET_ERROR) { printf("listen failed with error: %d\n", WSAGetLastError()); closesocket(ListenSocket); WSACleanup(); return 1; } printf("Waiting for client\n"); ClientSocket = accept(ListenSocket, NULL, NULL); if (ClientSocket == INVALID_SOCKET) { printf("accept failed with error: %d\n", WSAGetLastError()); closesocket(ListenSocket); WSACleanup(); return 1; } printf("Client acctped.\n"); closesocket(ListenSocket); do { iResult = recv(ClientSocket, recvbuf, recvbuflen, 0); if (iResult &gt; 0) { printf("Bytes received: %d\n", iResult); recvbuf[iResult] = '\0'; printf(recvbuf); char* testsend = "222 333\n444 555\n666 777" ; iSendResult = send( ClientSocket, testsend , strlen(testsend)+1 , 0 ); if (iSendResult == SOCKET_ERROR) { printf("send failed with error: %d\n", WSAGetLastError()); closesocket(ClientSocket); WSACleanup(); return 1; } printf("Bytes sent: %d\n", iSendResult); } else if (iResult == 0) printf("Connection closing...\n"); else { printf("recv failed with error: %d\n", WSAGetLastError()); closesocket(ClientSocket); WSACleanup(); return 1; } } while (iResult &gt; 0); iResult = shutdown(ClientSocket, SD_SEND); if (iResult == SOCKET_ERROR) { printf("shutdown failed with error: %d\n", WSAGetLastError()); closesocket(ClientSocket); WSACleanup(); return 1; } system("pause"); closesocket(ClientSocket); WSACleanup(); return 0; } </code></pre> <p>thank again.</p>

    1. CO`closesocket(ListenSocket);` -- is that intentional? What'll let you `accept()` on the next client...?

    2. COShould I delete closesocket(ListenSocket),that is closeSocket, and replace with accept() ??

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
