Body
<p>It's not as hard as you think. All you need to do is call the following method, passing in the command line for the restarted instance:</p> <pre><code>public static void RestartMe(string commandLine) { var myId = Process.GetCurrentProcess().Id; var myPath = Assembly.GetEntryAssembly().CodeBase.Replace("file:///", ""); var systemPath = typeof(object).Assembly.CodeBase.Replace("file:///", ""); var tempPath = Path.GetTempFileName(); File.WriteAllText(tempPath + ".cs", @" using System; using System.Diagnostics; public class App { public static void Main(string[] args) { try { Process.GetProcessById(" + myId + @").WaitForExit(); } catch {} Process.Start(""" + myPath + @""", Environment.CommandLine); } }"); var compiler = new ProcessStartInfo { FileName = Path.Combine(Path.GetDirectoryName(systemPath), "csc.exe"), Arguments = tempPath + ".cs", WorkingDirectory = Path.GetDirectoryName(tempPath), WindowStyle = ProcessWindowStyle.Hidden, }; var restarter = new ProcessStartInfo { FileName = tempPath + ".exe", Arguments = commandLine, WindowStyle = ProcessWindowStyle.Hidden, }; Process.Start(compiler).WaitForExit(); Process.Start(restarter); // No WaitForExit: restarter WaitForExits us instead File.Delete(tempPath); File.Delete(tempPath + ".cs"); Environment.Exit(0); } </code></pre> <p>How it works: This actually does create another "restarter" program but does it painlessly and automatically. The restarter program has the current process id and the executable filename built right into it. It will always find the compiler because NET Framework version ships with a compatible csc.exe in the same folder as System.dll.</p>

Guidance

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.
