25,899,116 | 0 | Powershell Environment Setup <p>This is a very quick question because I'm nervous to break my batch file/java environment or make my laptop explode.</p> <p>I used to used to execute a .bat file from cmd.exe to set my environment to java which worked and that but now I've upgraded to Windows Powershell.</p> <p>I've created a Powershell .ps version of the .bat file to set my java environment path as bellow.</p> <pre><code>echo "setting environment to Java" $env:path="$env:Path;C:\Program Files\Java\jdk1.8.0\bin" </code></pre> <p>This works fine but I was wondering if it's possible to include a second line to add the JDBC to the classpath as well</p> <pre><code>echo "setting environment to Java" $env:path="$env:Path;C:\Program Files\Java\jdk1.8.0\bin" $env:path="$env:Path;C:\Program Files (x86)\MySQL\MySQL Connector J" </code></pre> <p>just wanted a second opinion to avoid breaking everything (which I have done before).</p> <p>Will this end up setting my environment and adding an additional classpath or will it just overwrite the environment with just the MySQL Connector path.</p> |

14,197,211 | 0 | <p>Technically, the distinction is not really made between "unrecoverable error" and "recoverable error", but between checked exceptions and unchecked exceptions. Java <em>does</em> distinguish between them as follows:</p> <ul> <li>you <em>must</em> declare a checked exception in your <code>throws</code> clause; if using a method which throws a checked exception in a <code>try</code> block, you must either <code>catch</code> said exception or add this exception to your method's <code>throws</code> clause;</li> <li>you <em>may</em> declare an unchecked exception in your <code>throws</code> clause (not recommended); if using a method which throws an unchecked exception in a <code>try</code> block, you <em>may</em> <code>catch</code> that exception or add this exception to your method's <code>throws</code> clause (not recommended either).</li> </ul> <p>What is certainly not recommended, unless you <em>really</em> know what you are doing, is to "swallow" any kind of unchecked exception (ie, <code>catch</code> it with an empty block).</p> <p><code>Exception</code> is the base checked exception class; <code>Error</code> and <code>RuntimeException</code> are both unchecked exceptions, and so are all their subclasses. You will note that all three classes extend <code>Throwable</code>, and the javadoc for <code>Throwable</code> states that:</p> <blockquote> <p>For the purposes of compile-time checking of exceptions, Throwable and any subclass of Throwable that is not also a subclass of either RuntimeException or Error are regarded as checked exceptions.</p> </blockquote> <p>Classical examples of (in)famous unchecked exceptions:</p> <ul> <li><code>OutOfMemoryError</code> (extends <code>Error</code>);</li> <li><code>StackOverflowError</code> (extends <code>Error</code>);</li> <li><code>NullPointerException</code> (extends <code>RuntimeException</code>);</li> <li><code>IllegalArgumentException</code> (extends <code>RuntimeException</code>);</li> <li>etc etc.</li> </ul> <p>The only real difference between <code>Error</code> and <code>RuntimeException</code> is their estimated severity level, and is a "semantic" difference, not a technical difference: ultimately, both behave the same. Some IDEs (Intellij IDEA comes to mind) will also yell at you if you catch an <code>Error</code> but do not rethrow it.</p> |
30,327,271 | 0 | <p>Another possible workaround is instead of <code>Visibility</code> property use <code>Opacity</code>. In this case calling <code>Focus()</code> actually sets focus.</p> |

4,867,515 | 0 | <p>This is strange, if I'm reading your code correctly. Is there a reason that you can't maintain the collection and modify it (as opposed to re-creating it) so that you don't need to <code>RaisePropertyChanged</code> at all? That's what <code>ObservableCollection(of T)</code> does, after all. </p> <p>As I'm reading it, it might as well be an <code>IEnumerable(of T)</code>.</p> <p>(Creating a new <code>ObservableCollection(of T)</code> in a property getter is almost always a mistake. A <code>ReadOnlyObservableCollection(of T)</code> makes a lot more sense in that context.)</p> |

24,932,015 | 0 | <p>the empty view positioning in the layout is done 100% by the developer. Yes, that is by design, Android in general favours flexibility than easy of coding.</p> <p>If you look in the <a href="https://android.googlesource.com/platform/frameworks/base/+/refs/heads/master/core/java/android/widget/AdapterView.java" rel="nofollow"><code>AdapterView</code> source code</a> you'll see what I'm talking about, around line 737 you'll see this</p> <pre><code>mEmptyView.setVisibility(View.VISIBLE); </code></pre> <p>and this</p> <pre><code>if (mEmptyView != null) mEmptyView.setVisibility(View.GONE); </code></pre> <p>that means, all that the <code>ListView</code> do with the <code>emptyView</code> object you're passing is calling <code>setVisibility(boolean)</code> on it.</p> <p>So, now that we know it's just a normal layout, with no special treatment it's easier to handle it. If you don't want to write on your layout again and again the same XML for empty view, you can (should) have a empty_view.xml with just the empty view and inside each of your XML with the list you position the empty_view.xml using the <code><include></code> tag. Like this: <a href="http://developer.android.com/training/improving-layouts/reusing-layouts.html" rel="nofollow">http://developer.android.com/training/improving-layouts/reusing-layouts.html</a> and on the code you simply call:</p> <pre><code>listview.setEmptyView(root.findViewById(R.id.empty_view)); </code></pre> <p>or you can do it by code still... but that will involve setting layout params for the "parent" to proper organise it.</p> <p>hope it helps.</p> |

7,018,235 | 0 | <p>There are 2 things you can do in this instance.</p> <p>First of all you are correct, it is not accepting it because it is now a comma seperated list.</p> <p>Basically what you need to do is parse out that comma seperated list and use a function with an IN clause in your main query. Here's a very good article explaining how to do this:</p> <p><a href="http://blogs.lessthandot.com/index.php/DataMgmt/DataDesign/ssrs_multi_value_parameters" rel="nofollow">http://blogs.lessthandot.com/index.php/DataMgmt/DataDesign/ssrs_multi_value_parameters</a></p> <p>Otherwise another method would be to return everything in your SQL code and filter on the SSRS side. The way to do this would be to remove your where clause in SQL which filters your vouchers. This will then bring back all vouchers. In SSRS then set up a parameter the same way you normally would for a multi select parameter. Then in SSRS design view, you right click your table and go to properties. There is then a tab called filters. You can set up the filter here by saying do not show these vouchers. Basically it hides them.</p> <p>The first way I explanined is definitely the best way to do it as it is faster and can be re-used in the long run. It is very simple once all the function are setup.</p> |

28,872,797 | 0 | <p>Personally, for the admin account I won't go with the basic Spring Security user service, mainly because it lacks the flexibility of a DB-based user management approach. Indeed, you probably don't want to have your admin credentials established once for all, since they can be guessed or stolen or simply forgotten.</p> <p>Conversely, both password <strong>modification and recovery mechanisms</strong> should be put in place for all accounts, including the admin one (provided you use a trusted email account for password recovery, but this is a reasonable assumption).</p> <p>Getting concrete, my approach is the following: I use an <code>AuthenticationManager</code> where I inject a <code>CustomUserDetailService</code></p> <pre><code> <authentication-manager alias="authenticationManager"> <authentication-provider user-service-ref="customUserDetailsService" > <password-encoder ref="passwordEncoder" /> </authentication-provider> </authentication-manager> <b:bean id="passwordEncoder" class="org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder" /> </code></pre> <p>which is the following</p> <pre><code> @Service public class CustomUserDetailsService implements UserDetailsService{ @Autowired @Qualifier("userDaoImpl") private UserDao userDaoImpl; @Override @Transactional public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException { User user = userDaoImpl.loadByUsername(username); if (user != null) return user; else throw new UsernameNotFoundException(username + " not found."); } } </code></pre> <p>this works for all users, not only the admin.</p> <p>Now it comes <strong>the problem of having the admin account full functional when the application starts</strong>. This is accomplished by using an <strong>initialization</strong> bean to be executed at startup, detailed in the following</p> <pre><code> @Component public class Initializer { @Autowired private HibernateTransactionManager transactionManager; @Autowired @Qualifier("userDaoImpl") private UserDao userDao; @Autowired private CredentialsManager credentialsManager; private String resetPassword = "makeItHardToGuess"; private String adminUsername = "admin"; @PostConstruct private void init() { //since we are executing on startup, we need to use a TransactionTemplate directly as Spring may haven't setup transction capabilities yet TransactionTemplate trxTemplate = new TransactionTemplate(transactionManager); trxTemplate.execute(new TransactionCallbackWithoutResult() { @Override protected void doInTransactionWithoutResult(TransactionStatus status) { buildAdmin(); } }); } private void buildAdmin() { //here I try to retrieve the Admin from my persistence layer ProfiledUser admin = userDao.loadByUsername(adminUsername); try { //If the application is started for the first time (e.g., the admin is not in the DB) if(admin==null) { //create a user for the admin admin = new ProfiledUser(); //and fill her attributes accordingly admin.setUsername(adminUsername); admin.setPassword(credentialsManager.encodePassword(resetPassword)); admin.setAccountNonExpired(true); admin.setAccountNonLocked(true); admin.setCredentialsNonExpired(true); admin.setEnabled(true); admin.setEulaAccepted(true); Authority authority = new Authority(); authority.setAuthority("ROLE_ADMIN"); admin.getAuthorities().add(authority); } //if the application has previously been started (e.g., the admin is already present in the DB) else { //reset admin's attributes admin.setPassword(credentialsManager.encodePassword(resetPassword)); admin.getAuthorities().clear(); Authority authority = new Authority(); authority.setAuthority("ROLE_ADMIN"); admin.getAuthorities().add(authority); admin.setAccountNonExpired(true); admin.setAccountNonLocked(true); admin.setCredentialsNonExpired(true); admin.setEnabled(true); } userDao.save(admin); } catch (Exception e) { e.printStackTrace(); System.out.println("Errors occurred during initialization. System verification is required."); } } } </code></pre> <p>please note that the <code>@PostConstruct</code> annotation does not guarantee that spring has its transaction services available, that's why I had to manage the transaction my own. Please refer to <a href="http://stackoverflow.com/questions/19876637/how-to-get-transactions-to-a-postconstruct-cdi-bean-method/20740252#20740252">this</a> for more details.</p> |

The program '[73048] iisexpress.exe' has exited with code 0 (0x0). </code></pre> <p>However this can be temporarily fixed by 'emulating' in Internet Explorer and then with Chrome again, but this fix must be applied on every reboot in order for it to work.</p> <p>Why is this happening, and how can I properly debug in Chrome without the webserver exiting?</p> <p>I read <a href="http://stackoverflow.com/questions/19568762/how-can-i-prevent-visual-studio-2013-from-closing-my-iis-express-app-when-i-end">How can I prevent Visual Studio 2013 from closing my IIS Express app when I end debugging?</a> but however none of the solutions helped me in this respect, and that the issue is that Visual Studio seems to be closing <code>iisexpress.exe</code> when the debugging has started.</p> <p>Chrome runs each tab in a separate process (sandboxing), so perhaps it could be that Visual Studio is expecting Chrome's 'base' PID when Chrome actually spawns an entirely new PID for the new tab created when the 'emulator' starts?</p> <p>Is there any solution to this other than use Internet Explorer (or the 'fix') for debugging the site?</p> <p><a href="https://www.youtube.com/watch?v=GQKgpMPg6HM&feature=youtu.be" rel="nofollow">I have recorded what's happening here, and I still find it odd that Internet Explorer is able to 'cure' the problem temporarily.</a> </p> <p>I am using Visual Studio 2013 Ultimate with Windows 8.1 Pro (Media Centre Edition) and Chrome 40.0.2214.93 m.</p> |

23,643,308 | 0 | <p>Here are my thoughts. I would NEVER have any replication going on between dev and production. That's just way too risky in my opinion and not a Best Practice. Maybe that's not exactly what you're doing I'm not sure.</p> <p>Here's what I do and as far as I know everyone on my team:</p> <p>Our Dev server has a test database. This is a COPY from production. Personally I refresh it now and then so it's basically a snapshot.</p> <p>We have a local template for all dev work. We program in the template and refresh the test database. Typically we don't need to do a "restart task http" as part of the refresh process UNLESS we make a change to a managed bean or are working with SXD. Then yes we refresh the dev application and restart the server and test.</p> <p>In the OLD days I would have a production template on the production server. This was not a replica of anything but it inherited design from the DEV template. So to promote updates to production I'd first refresh the production template from the dev version. Then refresh the production app from the production template.</p> <p>In the world of source control and SourceTree where you have a feature branch, develop branch and default/production branch that kinda eliminates the need for a production template. I'm not in love with that but it is what it is. So we refresh production from our local templates and rely on SourceTree to make sure it's the correct branch at the time we refresh. I think it's a little more risky but this allows the ability to do real hotfixes and stuff.</p> <p>Historically I've not needed to do a restart task http but I've not promoted anything that uses SXD and even my managed bean promotions have been limited to this point. But I imagine I will need to do more with restarting the http task.</p> |

40,266,027 | 0 | <p>You can find the approximate number of active threads in the <code>ThreadPoolExecutor</code> by calling the <code>getActiveCount</code> method on it. However you shouldn't need to.</p> <p>From the <a href="https://docs.oracle.com/javase/8/docs/api/java/util/concurrent/Executors.html#newFixedThreadPool-int-" rel="nofollow">Java documentation for Executors.newFixedThreadPool</a></p> <blockquote> <p>Creates a thread pool that reuses a fixed number of threads operating off a shared unbounded queue. At any point, at most nThreads threads will be active processing tasks. If additional tasks are submitted when all threads are active, they will wait in the queue until a thread is available. If any thread terminates due to a failure during execution prior to shutdown, a new one will take its place if needed to execute subsequent tasks. The threads in the pool will exist until it is explicitly shutdown.</p> </blockquote> <p>So you should be able to keep submitting tasks to the thread pool and they will be picked up and run as threads become available.</p> <p>I also note that you are wrapping your tasks in <code>Thread</code> objects before submitting them to the thread pool which is not necessary.</p> |

In VS2010 you can write this:</p> <pre><code> AddHandler m_switchImageTimer.Tick, Sub(s, e) LoadNextImage() </code></pre> <p>In earlier versions, you need to either change the LoadNextImage() method declaration or use a little private helper method with the correct signature:</p> <pre><code> AddHandler m_switchImageTimer.Tick, AddressOf SwitchImageTimer_Tick ... Private Sub SwitchImageTimer_Tick(sender As Object, e As EventArgs) LoadNextImage() End Sub </code></pre> |
