Body
I am trying to download files from ftp server with this code: <pre><code>using (System.IO.FileStream fileStream = System.IO.File.OpenWrite(filePath)) { byte[] buffer = new byte[4096]; int bytesRead = responseStream.Read(buffer, 0, 4096); while (bytesRead > 0) { fileStream.Write(buffer, 0, bytesRead); bytesRead = responseStream.Read(buffer, 0, 4096); } } </code></pre> The creation of responseStream: <pre><code>System.IO.Stream responseStream = GetFileAsStream(url, username, password, false); public static System.IO.Stream GetFileAsStream(string ftpUrl, string username, string password, bool usePassive) { System.Net.FtpWebRequest request = (System.Net.FtpWebRequest)System.Net.WebRequest.Create(ftpUrl); request.KeepAlive = false; request.ReadWriteTimeout = 120000; request.Timeout = -1; request.UsePassive = usePassive; request.Credentials = new System.Net.NetworkCredential(username, password); request.Method = System.Net.WebRequestMethods.Ftp.DownloadFile; System.IO.Stream fileResponseStream; System.Net.FtpWebResponse fileResponse = (System.Net.FtpWebResponse)request.GetResponse(); fileResponseStream = fileResponse.GetResponseStream(); return fileResponseStream; } </code></pre> It works fine with smaller files but when a file is bigger (e.g. 150mb) the process hangs. For some reason the program does not understand that it has completed the download and it still tries to read more bytes. I prefer answers which do not include using external libraries. Thank you

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.
