    <p>I have written a service which starts a java.exe or ruby.exe (I know there are some solutions but I need my own service for some reasons).</p> <p>The service works find so far, I gather my configs from the registry, then start the services. When the service get stopped I get my processes and send a .Kill(). So far so good. But I found out, that the .Kill() is a problem due the fact that the ruby.exe (I use thin to start a service) or the java.exe (I start a SOLR with it) listen on a tcp socket port. If this port get in use and I kill the process windows will block the ports for 72 seconds (by design).</p> <p>If I do a solr:start and a thin -start from a shell command shell and stop it using the Ctrl+C the processes terminate and the port is available to use instantly.</p> <p>So my guess is: If I manage to send a ctrl-c to the process it terminate correctly.</p> <p>So I found this thread <a href="https://stackoverflow.com/questions/3719126/how-to-run-an-exe-from-windows-service-and-stop-service-when-the-exe-process-quit">How to Run an exe from windows service and stop service when the exe process quits?</a> where a proof of concept is posted. But by starting a process from a window service I don't have a windowHandle.</p> <p>I start my service like this:</p> <pre><code>m_process.StartInfo = new ProcessStartInfo { FileName = "java" , Arguments = arguments , UseShellExecute = true , WorkingDirectory = workDirectory , CreateNoWindow = false }; m_process.Start(); </code></pre> <p>Where arguments contais the jetty data to start the SOLR or in the ruby case I use "ruby.exe thin start ...".</p> <p>Now on stopping the service I tried:</p> <pre><code>[DllImport("user32.dll", CharSet = CharSet.Auto)] public static extern IntPtr FindWindow(string lpClassName, string lpWindowName); [DllImport("user32")] public static extern int SetForegroundWindow(IntPtr hwnd); [DllImport("user32.dll", SetLastError = true)] public static extern void SwitchToThisWindow(IntPtr hWnd, bool fAltTab); foreach (int i in m_processList) { MyLogEvent(Process.GetProcessById(i).MainModule.ModuleName); MyLogEvent(Process.GetProcessById(i).MainWindowTitle); try { IntPtr ptr = FindWindow(null, Process.GetProcessById(i).MainWindowTitle); { SetForegroundWindow(ptr); Thread.Sleep(1000); InputSimulator.SimulateModifiedKeyStroke(VirtualKeyCode.CONTROL, VirtualKeyCode.CANCEL); // SendKeys.Send("^{BREAK}"); Thread.Sleep(1000); } //Process.GetProcessById(i).Kill(); } catch(Exception ex) { MyLogEvent(ex.ToString()); Process.GetProcessById(i).Kill(); } } </code></pre> <p>But as I don't have a WindowTitle, I guess I don't even have a window I can't allocate the process like this.</p> <p>So does anyone have a idea how I can allocate process and send the stop signal to it? I can live with just killing the process, but this just a service restart impossible without waiting a long time. Thanks for any hints, tips and solutions.</p>

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.
