    <p>My application is running in Windows and I have to send some requests to the server. I am currently using libcurl.</p> <p>However there is a limitation when proxy server with authentication is involved before the request sent out to the server.</p> <p>I explored the options in libcurl but i could not able to make it work. If i hardcode the username / password it works. But I do not want to get the user name and password by my application; I would prefer that libcurl can requests these at the start of a transfer.</p> <p>Is there a different library i can use like winhttp or libcurl is the best one to use?</p> <p>Below are the curl settings done before making the request</p> <pre><code>curlResultCode = curl_easy_setopt(curlHandle, CURLOPT_URL, urlString.data()); curlResultCode = curl_easy_setopt(curlHandle, CURLOPT_WRITEFUNCTION, receiveDataCallback); curlResultCode = curl_easy_setopt(curlHandle, CURLOPT_WRITEDATA, &amp;curlPerformStorage); curlResultCode = curl_easy_setopt(curlHandle, CURLOPT_USERAGENT, "libcurl-agent/1.0"); curlResultCode = curl_easy_setopt(curlHandle, CURLOPT_FOLLOWLOCATION, 1); if(NULL != GetWindowsProxyConfig().lpszProxy){ LPWSTR wStr = GetWindowsProxyConfig().lpszProxy; char* buffer = new char[100]; wcstombs(buffer, wStr, 100) ; curlResultCode = curl_easy_setopt(curlHandle, CURLOPT_PROXY, "&lt;proxy_name&gt;"); curlResultCode = curl_easy_setopt(curlHandle, CURLOPT_PROXYPORT, &lt;number&gt;); curlResultCode = curl_easy_setopt(curlHandle, CURLOPT_HTTPAUTH, CURLAUTH_NONE); curlResultCode = curl_easy_setopt(curlHandle, CURLOPT_PROXYAUTH, CURLAUTH_BASIC); } else { curlResultCode = curl_easy_setopt(curlHandle, CURLOPT_PROXY, "&lt;proxy_name&gt;"); curlResultCode = curl_easy_setopt(curlHandle, CURLOPT_PROXYPORT, &lt;number&gt;); curlResultCode = curl_easy_setopt(curlHandle, CURLOPT_HTTPAUTH, CURLAUTH_NTLM); curlResultCode = curl_easy_setopt(curlHandle, CURLOPT_PROXYAUTH, CURLAUTH_NTLM); } curlResultCode = curl_easy_setopt(curlHandle, CURLOPT_USE_SSL, CURLUSESSL_ALL); curlResultCode = curl_easy_setopt(curlHandle, CURLOPT_SSL_VERIFYPEER, 1); curlResultCode = curl_easy_setopt(curlHandle, CURLOPT_SSL_VERIFYHOST, 2); if(proxyStr.length() &gt; 0){ curlResultCode = curl_easy_setopt(curlHandle, CURLOPT_HTTPPROXYTUNNEL, 1L); } curlResultCode = curl_easy_setopt(curlHandle, CURLOPT_FAILONERROR, 1); curlResultCode= curl_easy_setopt ( curlHandle, CURLOPT_ERRORBUFFER, errorbuffer ); int nConnectionTimeout = curlPerformStorage.GetConnectionTimeOut(); if (nConnectionTimeout &gt; 0) { curlResultCode = curl_easy_setopt(curlHandle, CURLOPT_CONNECTTIMEOUT, nConnectionTimeout); } int nTransferTimeout = curlPerformStorage.GetTransferTimeOut(); if (nTransferTimeout &gt; 0) { curlResultCode=curl_easy_setopt(curlHandle, CURLOPT_TIMEOUT, nTransferTimeout); } curlResultCode = curl_easy_setopt(curlHandle, CURLOPT_PROGRESSFUNCTION , ProgressCallback); if (curlResultCode == CURLE_OK) { curlResultCode = curl_easy_setopt(curlHandle, CURLOPT_NOPROGRESS, FALSE); curlResultCode= curl_easy_setopt(curlHandle, CURLOPT_PROGRESSDATA , &amp;curlPerformStorage); } curlResultCode = curl_easy_perform(curlHandle); if (curlResultCode != CURLE_OK) { } else { } curl_easy_reset(curlHandle); return curlResultCode; </code></pre>

    1. COWhat limitation are you referring to? If authentication works by hard coding the credentials it will work by providing them dynamically as well. Instead of just dumping libcurl post an SSCCE of how you're setting up and sending the HTTP request and see if the actual problem you're having can be resolved.

    2. COI think you have a better chance of fixing your problem if you post an SSCCE and an outline of what you're doing and what results you get.

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).
