Dear Team,

one morning, I tried to start OQ2014 and I got this error message and it would not start anymore:

Code:
---------------------------
Error
---------------------------
System.InvalidOperationException: There is an error in XML document (65, 3). ---> System.Xml.XmlException: Unexpected end of file has occurred. The following elements are not closed: Streamer, Streamers, Configuration. Line 65, position 3.

   at System.ComponentModel.BackgroundWorker.OnDoWork(DoWorkEventArgs e)

---------------------------
OK   
---------------------------


I have tried to uninstall, deleted all data and reinstall, same error. Any idea what the reason might be?

Regards
Mike

Hello,
looks like the configuration file was corrupted.
You can try delete it(or all config files)

location of the folder:
%AppData%\SmartQuant Ltd\OpenQuant 2014\config

thx. deleted all config files.

configuration.xml was corrupted.

it ended the file like this:
Code:
   ......
    </Streamer>
    <Streamer>
      <TypeName>SmartQuant.BarStreamer, SmartQuant, Version=1.2.0.0, Culture=neutral, PublicKeyToken=023ca4f8a69375d5</TypeName>


so it did not close the Streamer and Streamers for sure.

Regards
Mike

since OQ does not generate backup files by itself, this could help you to generate backup files and delete old files after x days:
I put this into my realtime scenario code...

Code:
//requirement: Install 7-zip from http://www.7-zip.org
         string appData = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData);   
         string strCmdText= string.Format("a \"{1}" + @"\SmartQuant Ltd\Backup {0}.7z" + "\" \"{1}" + @"\SmartQuant Ltd\OpenQuant 2014\" + "\" -ssw",DateTime.Now.ToString("yyyy MM dd HHmm"),appData);
         //Console.WriteLine(strCmdText);
         System.Diagnostics.Process cmd = new System.Diagnostics.Process();
         cmd.StartInfo.FileName = @"C:\Program Files\7-Zip\7z.exe";
         cmd.StartInfo.RedirectStandardInput = true;
         cmd.StartInfo.RedirectStandardOutput = true;
         cmd.StartInfo.CreateNoWindow = false;
         cmd.StartInfo.UseShellExecute = false;
         cmd.StartInfo.Arguments = strCmdText;
         cmd.Start();
         Console.WriteLine(cmd.StandardOutput.ReadToEnd());
         
         var files = new System.IO.DirectoryInfo(appData + @"\SmartQuant Ltd\").GetFiles("*.7z");
         foreach (var file in files)
         {
            if (DateTime.UtcNow - file.CreationTimeUtc > TimeSpan.FromDays(10))
            {
               System.IO.File.Delete(file.FullName);
            }
         }
