    <p>I'm interacting a website using <code>HttpRequest</code>s in C#<br> I can read the page contents but when i try to post some information back to the server, everything works correctly but not about the value of <code>TextArea</code>s in the page...<br> The text I'm trying to set for them is in <strong>Persian (Farsi)</strong> and the page I'm receiving is set for <strong>Windows-1256</strong> encoding... </p> <p>The problem is that the content of the <code>textarea</code> is not shown as I expect in Farsi! </p> <p><strong>Update:</strong> here is the code I use to send the request: </p> <pre><code>public static string PostMultipart(string URL, List&lt;RequestParameterInfo&gt; parameters, List&lt;string&gt; cookies, string referer, string acceptLanguage, string acceptCharset, object KeepAliveValue) { HttpWebRequest request = (HttpWebRequest)WebRequest.Create(new Uri(URL)); var boundary = "---------------------------7dc283270344"; var messageBytes = Encoding.UTF8.GetBytes("--" + boundary); foreach (var item in parameters) { var prefixBytes = Encoding.UTF8.GetBytes("\n"); var itemBytes = item.ToBytes(); var postfixBytes = Encoding.UTF8.GetBytes("\n--" + boundary); var startIndex = messageBytes.Length; Array.Resize&lt;byte&gt;(ref messageBytes, messageBytes.Length + itemBytes.Length + prefixBytes.Length + postfixBytes.Length); prefixBytes.CopyTo(messageBytes, startIndex); itemBytes.CopyTo(messageBytes, startIndex + prefixBytes.Length); postfixBytes.CopyTo(messageBytes, startIndex + prefixBytes.Length + itemBytes.Length); } var lastPostfixBytes = Encoding.UTF8.GetBytes("--"); var startIndex2 = messageBytes.Length; Array.Resize&lt;byte&gt;(ref messageBytes, messageBytes.Length + lastPostfixBytes.Length); lastPostfixBytes.CopyTo(messageBytes, startIndex2); request.Headers.Clear(); request.Accept = "application/x-ms-application, image/jpeg, application/xaml+xml, image/gif, image/pjpeg, application/x-ms-xbap, */*"; request.Headers.Add(HttpRequestHeader.Pragma, "no-cache"); request.ContentLength = messageBytes.Length; request.Referer = referer; request.UserAgent = "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .NET4.0C; .NET4.0E; InfoPath.3)"; request.ContentType = "multipart/form-data; boundary=" + boundary; request.Headers.Add(HttpRequestHeader.AcceptEncoding, "gzip, deflate"); request.Headers.Add(HttpRequestHeader.AcceptLanguage, acceptLanguage); if (!string.IsNullOrWhiteSpace(acceptCharset)) request.Headers.Add(HttpRequestHeader.AcceptCharset, acceptCharset); if (KeepAliveValue is Boolean) request.KeepAlive = (bool)KeepAliveValue; else request.Headers.Add(HttpRequestHeader.KeepAlive, (string)KeepAliveValue); request.Expect = null; request.CookieContainer = new CookieContainer(); foreach (var item in cookies) request.CookieContainer.SetCookies(new Uri(URL), item); request.AllowWriteStreamBuffering = true; request.Method = "POST"; using (var strm = request.GetRequestStream()) { strm.Write(messageBytes, 0, messageBytes.Length); } string resPage = ""; using (HttpWebResponse response = (HttpWebResponse)request.GetResponse()) { using (StreamReader srResponse = new StreamReader(response.GetResponseStream())) { resPage = srResponse.ReadToEnd(); } } return resPage; } </code></pre>

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).
