    copied!<p>Im having an odd issue with my implementation of a BackgroundWorker class. It is inside my program that will run some tests (for some hardware which is not important for this question). Here is my code for the BackgroundWorker:</p> <pre><code>public AllTests(MainMenu p) { InitializeComponent(); WindowStartupLocation = WindowStartupLocation.CenterScreen; this.parent = p; generateCaseLabels(tc.getTCs()); var testThread = new BackgroundWorker(); // Tell the testthread what to do testThread.DoWork += (sender, args) =&gt; { List&lt;BaseTestCase&gt; cases = tc.getTCs(); foreach ( BaseTestCase test in cases ) { test.execute(); while (!test.Done) { Thread.Sleep(500); } if (test.Passed) { passed.Add(test); } else { failed.Add(test); } } }; // Start the TestReport after the testing is completed testThread.RunWorkerCompleted += (sender, args) =&gt; { TestReport newWindow = new TestReport(parent, passed, failed); testThread.CancelAsync(); // reset the testThread (?) log.append(this, "--- DONE TESTING --------------------"); newWindow.Show(); this.Close(); }; // Start the testthread testThread.WorkerSupportsCancellation = true; testThread.RunWorkerAsync(); } </code></pre> <p>The odd thing that happens with this code is when started for the first time it works great, but when again navigation to this <code>AllTests</code> window the <code>TestReport</code> window is instantly opened, indicating that the <code>testThread.RunworkerCompleted</code> is immediately called. So my question: Does anyone know a smart thing to do with resetting the BackgroundWorker or something, or have an answer for this weird behavior?</p> <p>BTW here's how i call the AllTests Window:</p> <pre><code> private void startTests(object sender, RoutedEventArgs e) { log.append(this, "--- STARTING ALL TESTS --------------------"); AllTests newWindow = new AllTests(parent); newWindow.Show(); this.Close(); } </code></pre> <p>Thanks for your help! Robbert.</p> <p>PS If i made any spelling errors or the question is not clear enough; please excuse me- english is not my native language and this is my first post on StackOverflow! Thanks!</p>
