    <p>I have a windows service written in C# that acts as a proxy for a bunch of network devices to the back end database. For testing and also to add a simulation layer to test the back end I would like to have a GUI for the test operator to be able run the simulation. Also for a striped down version to send out as a demo. The GUI and service do not have to run at the same time. What is the best way to achieve this duel operation?</p> <p>Edit: Here is my solution combing stuff from <a href="https://stackoverflow.com/questions/421516">this question</a> , <a href="https://stackoverflow.com/questions/200163/am-i-running-as-a-service">Am I Running as a Service</a> and <a href="https://stackoverflow.com/questions/255056/install-a-net-windows-service-without-installutil-exe/255062#255062">Install a .NET windows service without InstallUtil.exe</a> using <a href="http://groups.google.co.uk/group/microsoft.public.dotnet.languages.csharp/browse_thread/thread/4d45e9ea5471cba4/4519371a77ed4a74" rel="nofollow noreferrer">this excellent code</a> by <a href="https://stackoverflow.com/users/23354/marc-gravell">Marc Gravell</a></p> <p>It uses the following line to test if to run the gui or run as service.</p> <pre><code> if (arg_gui || Environment.UserInteractive || Debugger.IsAttached) </code></pre> <p>Here is the code.</p> <pre><code> using System; using System.Collections; using System.Collections.Generic; using System.Linq; using System.Windows.Forms; using System.ComponentModel; using System.ServiceProcess; using System.Configuration.Install; using System.Diagnostics; namespace Form_Service { static class Program { /// /// The main entry point for the application. /// [STAThread] static int Main(string[] args) { bool arg_install = false; bool arg_uninstall = false; bool arg_gui = false; bool rethrow = false; try { foreach (string arg in args) { switch (arg) { case "-i": case "-install": arg_install = true; break; case "-u": case "-uninstall": arg_uninstall = true; break; case "-g": case "-gui": arg_gui = true; break; default: Console.Error.WriteLine("Argument not expected: " + arg); break; } } if (arg_uninstall) { Install(true, args); } if (arg_install) { Install(false, args); } if (!(arg_install || arg_uninstall)) { if (arg_gui || Environment.UserInteractive || Debugger.IsAttached) { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(new Form1()); } else { rethrow = true; // so that windows sees error...

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
