    <p>After lots and lots of trials, I found a solution that I like now. Basically, it works like this: 1. Get the Process ID of the process that you started 2. Pass this PID to a slightly modified version of SendSignal.exe, which sends Ctrl-C instead of Ctrl-Break</p> <p>Both steps are not completely straight forward, but nearly. For 1. you need to get the PID. Java does not provide any native way to get it. There are a number of threads discussing about how to do that best. I decided for one where you need to now the name (see getProcessIDs() in the code below).</p> <p>For 2. you need to have a tool that sends CTRL-C to a given PID. Again, Java does not do this. There are different ways to do it (e.g. using a wrapper in python or so), but all of them are somewhat complicated. I found the easiest one is to use a .exe-File to do the job. For this, I modified SendSingal.exe. You can get the sourcecode here: 1. Then, simply replace all occurences of "BREAK" (also in lowercase letters) by "C" and recompile.</p> <p>Rename the exe to SendSignalC.exe and put it in a subfolder ext\ of where you start Java. Then run the code below and happily call e.g. SendCTRLC.sendCtrlC("howeveryourprogramiscall.exe").</p> <pre><code>/** * Sends CTRL-C to running processes from Java (in Windows) * and ca get ProcessID(s) for a given process name. * IMPORTANT! * This function NEEDS SendSignalC.exe in the ext\ subdirectory. * @author Kai Goergen */ import java.io.*; import java.util.*; public class SendCTRLC() { /** * Get all PIDs for a given name and send CTRL-C to all * @param processName * @return */ public static List&lt;String&gt; sendCTRLC(String processName) { // get all ProcessIDs for the processName List&lt;String&gt; processIDs = getProcessIDs(processName); System.out.println("" + processIDs.size() + " PIDs found for " + processName + ": " + processIDs.toString()); for (String pid : processIDs) { // close it sendCTRLC(Integer.parseInt(pid)); } return processIDs; } /** * Send CTRL-C to the process using a given PID * @param processID */ public static void sendCTRLC(int processID) { System.out.println(" Sending CTRL+C to PID " + processID); try { Process p = Runtime.getRuntime().exec("cmd /c ext\\SendSignalC.exe " + processID); StreamGobbler.StreamGobblerLOGProcess(p); } catch (IOException e) { e.printStackTrace(); } } /** * Get List of PIDs for a given process name * @param processName * @return */ public static List&lt;String&gt; getProcessIDs(String processName) { List&lt;String&gt; processIDs = new ArrayList&lt;String&gt;(); try { String line; Process p = Runtime.getRuntime().exec("tasklist /v /fo csv"); BufferedReader input = new BufferedReader (new InputStreamReader(p.getInputStream())); while ((line = input.readLine()) != null) { if (!line.trim().equals("")) { // Pid is after the 1st ", thus it's argument 3 after splitting String currentProcessName = line.split("\"")[1]; // Pid is after the 3rd ", thus it's argument 3 after splitting String currentPID = line.split("\"")[3]; if (currentProcessName.equalsIgnoreCase(processName)) { processIDs.add(currentPID); } } } input.close(); } catch (Exception err) { err.printStackTrace(); } return processIDs; } } </code></pre> <p>PS: I would love to attach SendSignalC.exe here, but I don't think that I'm allowed to. Anyhow, the changes are simple and straight-forward if you have a running cpp-compiler...</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.
