I have it working with www.microsoft.com but when i change the domain to www.atomic-gaming.info (my domain) i get an error 12029 and if i change the link to www.yahoo.com i get an error 12017</p> <p>code</p> <pre><code> DWORD dwSize = 0; DWORD dwDownloaded = 0; LPSTR pszOutBuffer; BOOL bResults = FALSE; HINTERNET hSession = NULL, hConnect = NULL, hRequest = NULL; // Use WinHttpOpen to obtain a session handle. hSession = WinHttpOpen( L"WinHTTP Example/1.0", WINHTTP_ACCESS_TYPE_DEFAULT_PROXY, WINHTTP_NO_PROXY_NAME, WINHTTP_NO_PROXY_BYPASS, 0 ); WinHttpSetOption(hSession, WINHTTP_OPTION_REDIRECT_POLICY_ALWAYS,NULL,NULL); // Specify an HTTP server. if( hSession ) hConnect = WinHttpConnect( hSession, L"www.microsoft.com", INTERNET_DEFAULT_HTTPS_PORT, 0 ); // Create an HTTP request handle. if( hConnect ) hRequest = WinHttpOpenRequest( hConnect, L"GET", NULL, NULL, WINHTTP_NO_REFERER, WINHTTP_DEFAULT_ACCEPT_TYPES, WINHTTP_FLAG_SECURE ); // Send a request. if( hRequest ) bResults = WinHttpSendRequest( hRequest, WINHTTP_NO_ADDITIONAL_HEADERS, 0, WINHTTP_NO_REQUEST_DATA, 0, 0, 0 ); // End the request. if( bResults ) bResults = WinHttpReceiveResponse( hRequest, NULL ); // Keep checking for data until there is nothing left. if( bResults ) { do { // Check for available data. dwSize = 0; if( !WinHttpQueryDataAvailable( hRequest, &amp;dwSize ) ) printf( "Error %u in WinHttpQueryDataAvailable.\n", GetLastError( ) ); // Allocate space for the buffer. pszOutBuffer = new char[dwSize+1]; if( !pszOutBuffer ) { printf( "Out of memory\n" ); dwSize=0; } else { // Read the data.

    2. CO@Waldermort For what it's worth, 12029 is ERROR_WINHTTP_CANNOT_CONNECT and 12017 is ERROR_WINHTTP_OPERATION_CANCELLED

    3. CO@IgorTandetnik I was hoping to encourage the poster to first use google to identify the error, perhaps giving him insight into what his problem might be. On another note, I really wish MS had used enumerations instead of error codes, making them easier to read.

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).
