    text
    copied!<p>I have a very old legacy Java application that I'd like to automate from C#. The problem is we don't have the source code of the application and the programmer has long since left the company. I could probably 'decompile' the .jar file but I'm no java programmer either, and I don't think that having access to the source code (without comments) will get me any further.</p> <p>So far i managed to (kinda successfully) automate the application's login dialog, using the following code (I'm polling in a loop because there might be more than one instance of the Java app):</p> <pre><code>while (true) { var processes = Process.GetProcesses().Where(p =&gt; p.MainWindowTitle.Equals("Title of Java Login Window")); foreach (var process in processes) { var handle = process.MainWindowHandle; SetForegroundWindow(handle); await Task.Delay(500); SendKeys.SendWait("the password"); SendKeys.SendWait("{TAB}"); SendKeys.SendWait("the username"); SendKeys.SendWait("{ENTER}"); await Task.Delay(3000); } await Task.Delay(500); } </code></pre> <p>Now the problem is I'm unable to grab the contents of the Java window. For example, there might be a problem with the login, like a wrong user or password. So I wan't to check the Java window for login failure messages.</p> <p>Is there a way to access the actual content (text) of the Java window?</p> <p>Also, all instances of the Java Application share the same PID, because in reality it's just one java.exe process running all the applications. Is there a way to differentiate between the applications? It obviously can't be done using the PID ...</p>
