  • Strategy for unsubscribing event handlers

    - by stiank81
    In my WPF application I have a View that is given a ViewModel, and when given this View it adds event handlers to the ViewModel's PropertyChanged event. When some action occur in the GUI I remove the View and add another View to the holding container - where this new one is bound to the same ViewModel. After this has happened the old View still keeps handling PropertyChanged events in the ViewModel. I'm assuming this happens because the View hasn't been collected by the Garbage Collector yet, and therefore is alive? Well - I need it to stop. My assumption is that I need to manually detach the event handler from the ViewModel? Is there a best-practice on how to handle this?

  • Upgrading Agent Controllers in Oracle Enterprise Manager Ops Center 12c

    - by S Stelting
    Oracle Enterprise Manager Ops Center 12c recently released an upgrade for Solaris Agent Controllers. In this week's blog post, we'll show you how to upgrade agent controllers. Detailed instructions about upgrading Agent Controllers are available in the product documentation here. This blog post uses an Enterprise Controller which is configured for connected mode operation. If you'd like to apply the agent update in a disconnected installation, additional instructions are available here. Step 1: Download Agent Controller Updates With a connected mode Ops Center installation, you can check for product updates at any time by selecting the Enterprise Controller from the left-hand Administration navigation tab. Select the right-hand Action link “Ops Center Downloads” to open a pop-up dialog displaying any new product updates. In this example, the Enterprise Controller has already been upgraded to the latest version (Update 1, also shown as build version 2076) so only the Agent Controller updates will appear. There are three updates available: one for Solaris 10 X86, one for Solaris 8-10 SPARC, and one for all versions of Solaris 11. Note that the last update in the screen shot is the Solaris 11 update; for details on any of the downloads, place your mouse over the information icon under the details column for a pop-up text region. Select the software to download and click the Next button to display the Ops Center license agreement. Review and click the check box to accept the license agreement, then click the Next button to begin downloading the software. The status screen shows the current download status. If desired, you can perform the downloads as a background job. Simply click the check box, then click the next button to proceed to the summary screen. The summary screen shows the updates to be downloaded as well as the current status. Clicking the Finish button will close the dialog and return to the Browser UI. The download job will continue to run in Ops Center and progress can still be viewed from the jobs menu at the bottom of the browser window. Step 2: Check the Version of Existing Agent Controllers After the download job completes, you can check the availability of agent updates as well as the current versions of your Agent Controllers from the left-hand Assets navigation tab. Select “Operating Systems” from the pull-down tab lets to display only OS assets. Next, select “Solaris” in the left-hand tab to display the Solaris assets. Finally, select the Summary tab in the center display panel to show which versions of agent controllers are installed in your data center. Notice that a few of the OS assets are not displayed in the Agent Controllers tab. Ops Center will not display OS instances which do not have an Agent Controller installation. This includes Enterprise Controllers and Proxy Controllers (unless the agent has been activated on the OS instance) and and OS instances using agentless management. For Agent Controllers which support an update, the version of agent software (in this example, 2083) appears to the right of the currently installed version. Step 3: Upgrade Your Agent Controllers If desired, you can upgrade agent controllers from the previous screen by selecting the desired systems and clicking the upgrade button. Alternatively, you can click the link “Upgrade All Agent Controllers” in the right-hand Actions menu: In either case, a pop-up dialog lets you start the upgrade process. The first screen in the dialog lets you choose the upgrade method: Ops Center provides three ways to upgrade agent controllers: Automatic Upgrade: If Agent Controllers are running on all assets, Ops Center can automatically upgrade the software to the latest version without requiring any login credentials to the system SSH using a single set of credentials: If all assets use the same login credentials, you can apply a single set to all assets for the upgrade process. The log-in credentials are the same ones used for asset discovery and management, which are stored in the Plan Management navigation tab under Credentials. SSH using individual credentials: If assets use different login credentials, you can select a different set for each asset. After selecting the upgrade method, click the Next button to proceed to the summary screen. Click the Finish button to close the pop-up dialog and start the upgrade job for the agent controllers. The upgrade job runs a series of tasks in parallel, and will upgrade all agents which have been selected. Once the job completes, the OS instances in your data center will be upgraded and running the latest version of Agent Controller software.

  • Any way to trigger interface orientation check?

    - by Johnny Tee
    My app is going from a flipside view (only one orientation) to its main view (can have any sort of orientation. When I go from flipside back to main view, the main view's orientation is not checked and changed immediately. I need a way to trigger the built in orientation check that happens in willRotateToInterfaceOrientation so that the orientation is correct when the user goes from flipside view to main view. Any help is appreciated. I saw another question about this but didn't see a definitive answer. Thanks!

  • UITableViewController's TableView becomes NULL

    - by Travis
    I have UITableViewController (initiated by the Navigation-based app project template). I am overriding loadView and putting up an alternative view (w/ a UILabel and UIActivityIndicator) to display while the table's contents is loading. When the loading is done, I remove the loading view and try to display the table view but I see that it's NULL. So in the simulator I see my loading view and then when the loading's done the view disappears but my tableview never comes. I'm confused what the difference is between self.view and self.tableView in my UITableViewController and how I can exchagn

  • UIView animation doesn't work first time

    - by BobC
    Hello everybody, I have a seachButton in the navigation bar which upon hitting calls following method: - (IBAction)search:(id)sender { if (nil == searchViewController) searchViewController = [[SearchViewController alloc] initWithNibName:@"SearchViewController" bundle:nil]; searchViewController.view.backgroundColor = [UIColor clearColor]; [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:1.0]; [UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:searchViewController.view cache:NO]; [self.view addSubview:searchViewController.view]; [UIView commitAnimations]; } It should load SearchViewController.xib which contains a view with UISearchBar and two buttons. When I call the search method for the first time, the view appears very quickly with some weird animation, when I call it again, the animation is alright. Does anyone have a clue what could be wrong?

  • Global variable life in Javascript - destroyed on a reload?

    - by Paul Nathan
    (I am learning Javascript) Problem: A page I am working on has 2 views, a data entry view with a textbox and a data rendering view. There is a a href src="currentpage#" link that switches between the 2 views. In order to transmit data from view to view, the javascript parses it from the current HTML and pushes it into the correct form for the other view. This is ugly and I want to refactor it out, ideally into some sort of global where it can be neatly rendered down into the view on command (I'm refactoring the code base to a point where I can AJAX it from a server). However, I am not certain about scoping rules and variable life in JS.

  • Lazy Tables app from iphone

    - by Warrior
    I am new to iphone development. I have parsed a youtube file and displaying its contents with the image in the table view. But the scrolling has become slower because of displaying image.So i want to display the image as the lazy tables program from apple docs.Since they have used navigation based application , their rootviewcontroller loads first and then the delegate class call the parsing ,and when they reload the table view, the contents are displayed. The data array count shows 25. I am using a view controller to display the tables on the present modal view, more over when i run my application, first delegate methods call the parsing. So when i click the youtube icon in my landing page it navigates to table view. So by this time data array count shows 0. I have created table view in interface builder and set the outlets to the file owner properly. Please help me out. I want to increasing the scrolling performance. Thanks.

  • Xml files stop being served by IIS6 after allowing .net to process the .xml extension

    - by Brian Surowiec
    I added a route into my site to allow for a sitemap and everything worked fine in IIS7 but once I deployed the route stopped working. Since the live server is running IIS6 I needed to put a new mapping in for .xml to be processed by .net and then it started to work. My issue though is on every other xml file on the site now. I keep getting a 404 error when trying to view xml files, but the sitemap.xml route works. Is this a routing issue or an IIS setup issue? Here are my routes if it will help routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "Gallery-Group-View", "Projects/{groupId}", new { controller = "Gallery", action = "GalleryList", groupId = "" }); routes.MapRoute( "Gallery-List-View", "Projects/{groupId}/{galleryId}", new { controller = "Gallery", action = "GalleryView", groupId = "", galleryId = "" }); routes.MapRoute( "Sitemap", "Sitemap.xml", new { controller = "XML", action = "Sitemap" } ); routes.MapRoute( "Default", "{controller}/{action}/{id}", new { controller = "Home", action = "Index", id = "" } );

  • pushViewController for same instance - only for animation purpose

    - by techastute
    Hi there, I am having single table view in a view controller. That table view lists the countries first. When I click on a country(row), it has to push the same view controller's view with cities under that country. I need to see the slide animation, which we usally get while pushing views in navigator. Is it possible to use the pushViewController for the same view controller by calling the tableView reloadData with city data (This should happen when country is selected) ? Please let me know whether it is possible.. Thanks in advance.. Raj

  • Android WebViewClient problem

    - by deSelby
    I've defined a private class that extends WebViewClient and set my WebView's client to an instance of that class (webView01.setWebViewClient(new Callback());). The class definition is as follows: private class Callback extends WebViewClient { public void onLoadResource (WebView view, String url) { } public void onPageStarted (WebView view, String url, Bitmap favicon) { } public void onPageFinished (WebView view, String url) { Animation anim = AnimationUtils.loadAnimation(MyNews.this, R.anim.webviewanim); view.startAnimation(anim); } public void onReceivedError (WebView view, int errorCode, String description, String failingUrl) { } public boolean shouldOverrideUrlLoading (WebView view, String url) { Log.e("loading url", url); return false; } } My problem is that onPageFinished is definitely getting called, but shouldOverrideUrlLoading is never being called. What am I doing wrong here?

  • noindex, follow on list views?

    - by Fabrizio
    On one of our client's website we have lot's of list views with links to detail views. (Image a blog with the posts overview and the single pages). The detail views don't change, but the list views will change when new items come up. The pages displaying the list view don't contain any other valuable content. So my question is: Does it make sense to define meta "noindex, follow" on the list view pages (and of course "index, follow" on the detail views) to prevent search engines to point to the list views when the keyword is found in the title or teaser of the list view. By the time the visitor clicks on the list view search result it might have changed and the content is not visible anymore, whereas if he goes directly to the single view he will definitly find what he was searching for? Related question: The startpage also contains mainly a list view. Is it a bad idea to have the start page not indexed? Any SEO gurus here? :) Thanks, Fabrizio.

  • Ruby get inheriting class

    - by Brian D.
    I'm working on creating my first plugin for rails. I'm still pretty new to ruby and I was wondering if its possible to get the inheriting class? For example, I'm trying to create a plugin that will allow unit testing and functional testing when you are not using migrations. What I'm trying to do is initialize a class variable named controller to be initialized to the type of controller that is being tested. If I have a base class ControllerTest: class ControllerTest < Test::Unit::TestCase attr_accessor :controller def initialize super @controller = "call function that will find the inheriting classes name and create an instance of that controller type." end end So what I'm currently stuck on is getting the name of the inheriting class. Is this possible? And if not, does anyone know another way on how I could go about implementing this? Thanks in advance.

  • ASP.NET MVC Actions that return different views, or just make a ton of Actions?

    - by Nate Bross
    So, I am in a situation, where I need to display a different view based on the "Role" that the authenticated user has. I'm wondering which approach is best here: [Authorize(Roles="Admin")] public ActionResult AdminList(int? divID, int? subDivID) { var data = GetListItems(divID.Value, subDivID.Value); return View(data); } [Authorize(Roles = "Consultant")] public ActionResult ConsultantList(int? divID, int? subDivID) { var data = GetListItems(divID.Value, subDivID.Value); return View(data); } or should I do something like this [Authorize] public ActionResult List(int? divID, int? subDivID) { var data = GetListItems(divID.Value, subDivID.Value); if(HttpContenxt.User.IsInRole("Admin") { return View("AdminList", data ); } if(HttpContenxt.User.IsInRole("Consultant") { return View("ConsultantList", data ); } return View("NotFound"); }

  • ASP.NET MVC: Route to URL

    - by JamesBrownIsDead
    What's the easiest way to get the URL (relative or absolute) to a Route in MVC? I saw this code here on SO but it seems a little verbose and doesn't enumerate the RouteTable. Example: List<string> urlList = new List<string>(); urlList.Add(GetUrl(new { controller = "Help", action = "Edit" })); urlList.Add(GetUrl(new { controller = "Help", action = "Create" })); urlList.Add(GetUrl(new { controller = "About", action = "Company" })); urlList.Add(GetUrl(new { controller = "About", action = "Management" })); With: protected string GetUrl(object routeValues) { RouteValueDictionary values = new RouteValueDictionary(routeValues); RequestContext context = new RequestContext(HttpContext, RouteData); string url = RouteTable.Routes.GetVirtualPath(context, values).VirtualPath; return new Uri(Request.Url, url).AbsoluteUri; } What's a better way to examine the RouteTable and get a URL for a given controller and action?

  • Loading different portrait/landscape UIViews

    - by Tronic
    Hi, I have following View COntroller structure: ScrollViewController LandscapeViewController PortraitViewController Each with its own .nib The app starts in landscape mode where many landscape views are added to a scrollview. Each landscape view has its specific portrait view, so I have to assign like ID's to each of this views. Can you tell me, how I can load the specific portrait view for each landscape view when rotating the device? Do I have to make two scroll views? One for landscape, one for portrait? Or is it possible to just scroll through the landscape scrollview an load just one portrait view with the right content based on an ID? How could I implement that? The data comes from a property list. Thanks in advance!

  • fuzzy DISTINCT Values

    - by user982853
    I have a database of real estate listings and need to return a list of neighborhoods. Right now I am using mysql DISTINCT which returns all of the distinct values. My probelm is that there is a lot of neighborhoods that have similar names: example: Park View Sub 1 Park View Park View Sub 2 Park View Sub 3 Great Lake Sub 1 Great Lake Sub 2 Great Lake Great Lake Sub 3 I am looking for an easy php or mysql solution that would recognize that "Park View" and "Great Lake" already exists and ONLY return "Park View" and "Great Lake". My initial thought is to some how get the sort order by length so that the short values are at the top and then loop through using strstr. This sound like a large task I am wondering if there is a function either in mysql or php that would easily do this.

  • TTPhotoViewController thumbnails rotate but images don't

    - by Koray Balci
    I have PhotoTest1Controller very similiar to the one in Three20 samples. I implemented necessary shouldRotate methods in necessary places in UITabBarController and UINavController derived classes as well as the table that contains PhotoTest1Controller. A funny thing is happening, when in thumbnail mode, the view rotates properly, but when showing a picture it does not respond to rotation. Moreover, If I rotate in thumbnail view and then switch to single image view in that rotation, I find that the image is properly rotated in the background. It only ignores rotation when it is the topmost view! So, my understanding is that shouldRotate events are properly propagated, but for some reason single image view does not rotate when in top view, unlike the example code which is %98 equal to my code...

  • ASP.NET MVC Generic Controllers and Spring.NET

    - by Jason
    Hello, I am creating an application using ASP.NET MVC (2) and Spring.NET. Since most of my Controller implementations just implement the similar CRUD operations, I would like to just create a single Generic controller, as explained here: http://stackoverflow.com/questions/848904/in-asp-net-mvc-is-it-possible-to-make-a-generic-controller However, the above example doesn't take DI frameworks into consideration. What I'm thinking is to create this (warning: this is an ugly mass of code I need help with): public SpringGenericControllerFactory : DefaultControllerFactory { public IController CreateController(RequestContext requestContext, string controllerName) { // Determine the controller type to return Type controllerType = Type.GetType("MyController").MakeGenericType(Type.GetType(controllerName)); // Return the controller return Activator.CreateInstance(controllerType) as IController; } } The entries in objects.xml would look something like this: <object id="controllerFactory" type="Application.Controllers.SpringGenericControllerFactory" /> <object id="DepartmentController" factory-method="CreateController" factory-object="controllerFactory" /> Can anyone pick through this and offer advice?

  • IconDownloader, problem with lazy downloading

    - by Junior B.
    My problem is simple to be described but it seems to be hard to solve. The problem is loading icons, with a custom class like IconDownloader.m provided by an official example from Apple, avoiding crashes if I release the view. I've added the IconDownloader class to my app, but it's clear that this approach is good only if the tableview is the root. The big problem is when the view is not the root one. F.e: if I start to scroll my second view (the app now load the icons) and, without leaving it the time to finish the download, I go back to root, the app crash because the view that have to be updated with new icons doesn't exist anymore. One possible solution could be implement an OperationQueue in the view, but with this approach I've to stop the queue when I change the view and restart it when I come back and the idea to have N queues don't make me enthusiastic. Anyone found a good solution for this problem?

  • TabHost disappears after locking the phone and reopening it:

    - by Emil Adz
    I have a weird issue with my TabHost in my FragmentActivity that contains a ViewPager. The problem is that when I close my phone (press the power button) while I use my application, and then I turn back the phone and my application gets reopened, at this point my TabHost is missing. So the closing of my phone is causes the TabHost to disappear. My guess would be that I need to save my tabHost state in the saveInstanceState object, and restore it in onResume I only have no idea how it's done. here is my code for the FragmentActivity: public class TabsViewPagerFragmentActivity extends FragmentActivity implements ViewPager.OnPageChangeListener, TabHost.OnTabChangeListener { static final String TAG = TabsViewPagerFragmentActivity.class.getSimpleName(); private TabHost mTabHost; private ViewPager mViewPager; private HashMap<String, TabInfo> mapTabInfo; public ViewPagerAdapter mPagerAdapter; private TextView tvReportName, tvTabTitle; private Button bBackToParameters; private Dialog progressDialog; private SGRaportManagerAppObj application; private int numberOfTabs = 0; private Display display; public static final int POPUP_MARGIN = 6; LeftSideMenu leftSideMenu; public void NotifyTabActivityViewPagerAdapter() { mPagerAdapter.notifyDataSetChanged(); } public ViewPagerAdapter getTabActivityViewPagerAdapter() { return mPagerAdapter; } public ViewPager getTabActivityViewPager() { return mViewPager; } public void setCurrentTabTitle (String title) { tvTabTitle.setText(title); Log.d(TAG, "set tab title from activity: "+title); } /** * Maintains extrinsic info of a tab's construct */ private class TabInfo { private String tag; private Class<?> clss; private Bundle args; private Fragment fragment;
