    <p>I have a program where i am trying to call REST API of amazon.Here is the code</p> <pre><code>int main() { char * serveraddr = "myuser.s3.amazonaws.com"; int iProtocolPort = 0; char szSmtpServerName[64] = ""; char szBuffer[4096] = ""; char szMsgLine[1024] = ""; SOCKET hServer; WSADATA WSData; LPHOSTENT lpHostEntry; LPSERVENT lpServEntry; SOCKADDR_IN SockAddr; // Load command-line args lstrcpyA(szSmtpServerName, serveraddr); // Attempt to intialize WinSock (1.1 or later) if(WSAStartup(WINSOCK_VERSION, &amp;WSData)) { return 1; } // Lookup email server's IP address. lpHostEntry = gethostbyname(szSmtpServerName); if(!lpHostEntry) { cout &lt;&lt; "Cannot find SMTP mail server " &lt;&lt; szSmtpServerName &lt;&lt; endl; return 1; } // Create a TCP/IP socket, no specific protocol hServer = socket(PF_INET, SOCK_STREAM, IPPROTO_TCP); if(hServer == INVALID_SOCKET) { cout &lt;&lt; "Cannot open mail server socket" &lt;&lt; endl; return 1; } // Use the HTTP default port if no other port is specified iProtocolPort = htons(80); // Setup a Socket Address structure SockAddr.sin_family = AF_INET; SockAddr.sin_port = iProtocolPort; SockAddr.sin_addr = *((LPIN_ADDR)*lpHostEntry-&gt;h_addr_list); // Connect the Socket if(connect(hServer, (PSOCKADDR) &amp;SockAddr, sizeof(SockAddr))) { cout &lt;&lt; "Error connecting to Server socket" &lt;&lt; endl; printf("Last error = %d\n",WSAGetLastError()); return 1; } int content_len = 0; char *query=NULL; char * tpl = (char *)"POST /test.txt?uploads HTTP/1.1\r\nHost: %s\r\n" "Authorization: AWS ABCDEFDGHIJKLMN:%s\r\n" "Date: %s\r\n\r\n"; //Get Time stamp char *currdate = currentDateTime(); char *sign = NULL; char signString [32]= {0}; //Generate sign string int ret = GenedateSignature(&amp;sign,currdate); memcpy(signString,sign,28); query = (char *)malloc(512*(sizeof(char ))); if(query == NULL) { LogMessage(LOG_FILE,"\nQuery == NULL \n"); return FALSE; } memset(query,0,512); content_len=0;//strlen((char*)Status); sprintf(query, tpl, (char*)serveraddr,signString,currdate); //Send data int r = send(hServer, query, strlen(query), 0); //Recv data recv(hServer, szBuffer, sizeof(szBuffer), 0); printf("\n%s",szBuffer); free(query); // Close server socket and prepare to exit. closesocket(hServer); WSACleanup(); return 0; } </code></pre> <p>when i send the data i get the number of bytes written but when i call recv i get <strong><em>"404 not found error"</em></strong></p> <p>Is it possible to call the REST API like this? If yes What i am doing wrong?</p> <p>Thanks</p>

    1. COThe API stuff looks ok (although there could be something subtle wrong?) but you really should check the return value from `send` and `recv`. It might be only sending half your data!

    2. COWhat is the POST on test.txt supposed to do? Have you checked that the file is there? Does a similar call work in some other programming language or tool?

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).
