  • Strategy in exporting to Excel with formatting from ASP.NET?

    - by Jiho Han
    So this is another exporting to Excel question. I have a page that has a table with formatting by stylesheet. When I export the page by setting the ContentType to application/excel and Content-Disposition to attachment, I can export the table to Excel (not CSV). However, it loses all formatting. I think it's because Excel does not load CSS and I guess that's reasonable. So, in a scenario where I have to show the table on the web and also export to Excel, both with similar (even if not exact) formatting, what would be the best approach without using something like NPOI? I am trying to minimize the work and keep the single template if possible. Is it necessary for me to create two separate templates: one with stylesheet, the other with embedded style in the table itself for Excel? Having a single template with conditional formatting inside would be very messy. Any ideas?

  • webservice request issue with dynamic request inputs

  • Django comparing model instances for equality

    - by orokusaki
    I understand that, with a singleton situation, you can perform such an operation as: spam == eggs and if spam and eggs are instances of the same class with all the same attribute values, it will return True. In a Django model, this is natural because two separate instances of a model won't ever be the same unless they have the same .pk value. The problem with this is that if a reference to an instance has attributes that have been updated by middleware somewhere along the way and it hasn't been saved, and you're trying to it to another variable holding a reference to an instance of the same model, it will return False of course because they have different values for some of the attributes. Obviously I don't need something like a singleton , but I'm wondering if there some official Djangonic (ha, a new word) method for checking this, or if I should simply check that the .pk value is the same with: spam.pk == eggs.pk I'm sorry if this was a huge waste of time, but it just seems like there might be a method for doing this, and something I'm missing that I'll regret down the road if I don't find it.

  • cast across classloader?

    - by IttayD
    How can I do this: class Foo { public static Foo get() throws Exception { ClassLoader cl = new URLClassLoader(new URL[]{"foo.jar"}, null); // Foo.class is in foo.jar return (Foo)cl.loadClass("Foo").newInstance(); // fails on class cast } } What I need is for the JVM to consider the Foo instance from cl as if it is an instance of Foo from the classloader of the executing code. I have seen these approaches, none of them good for me (the above example is a toy example): Load the class (or a separate interface) by a class loader that is a parent of both the calling code and created classloader Serialize and deserialize the object.

  • Right clicking on QHeaderView inside of QTreeView

    - by taynaron
    I've written a descendant of QTreeView with multiple columns. I want to create a popup menu that appears whe nthe user right-clicks over the column headers. I have tried catching signals from QTreeView for this, but QTreeView doesn't seem to emit signals on the headers. QTreeView.header() does. I therefore believe I must either: 1: connect one of QHeaderView's signals to a popup function - I have been unable to find a signal that is triggered on a single right click - I have tried sectionClicked, sectionHandleDoubleClicked, sectionDoubleClicked, sectionPressed (not surprised the double click functions didn't catch a single right click - but they do catch a double right click) self.header().sectionClicked.connect(self.headerMenu) self.header().sectionHandleDoubleClicked.connect(self.headerMenu) self.header().sectionDoubleClicked.connect(self.headerMenu) self.header().sectionPressed.connect(self.headerMenu) or, 2: write a descendant of QHeaderView with my own MousePressEvent function, and use that for my headers. I have so far been unsuccessful in connecting the new header class to the QTreeView descendant. I keep getting a Segmentation Fault on runtime, with no more explanation. #in DiceView's init, where DiceHeaders is the QHeaderView descendant self.setHeader(DiceHeaders()) Any ideas?

  • Resolving HttpRequestScoped Instances outside of a HttpRequest in Autofac

    - by Page Brooks
    Suppose I have a dependency that is registered as HttpRequestScoped so there is only one instance per request. How could I resolve a dependency of the same type outside of an HttpRequest? For example: // Global.asax.cs Registration builder.Register(c => new MyDataContext(connString)).As<IDatabase>().HttpRequestScoped(); _containerProvider = new ContainerProvider(builder.Build()); // This event handler gets fired outside of a request // when a cached item is removed from the cache. public void CacheItemRemoved(string k, object v, CacheItemRemovedReason r) { // I'm trying to resolve like so, but this doesn't work... var dataContext = _containerProvider.ApplicationContainer.Resolve<IDatabase>(); // Do stuff with data context. } The above code throws a DependencyResolutionException when it executes the CacheItemRemoved handler: No scope matching the expression 'value(Autofac.Builder.RegistrationBuilder`3+<c__DisplayClass0[MyApp.Core.Data.MyDataContext,Autofac.Builder.SimpleActivatorData,Autofac.Builder.SingleRegistrationStyle]).lifetimeScopeTag.Equals(scope.Tag)' is visible from the scope in which the instance was requested.

  • Problem connecting to postgres with Kohana 3 database module on OS X Snow Leopard

Any ideas are welcome. One other note is that I know my build of PHP can access this postgresql db since I'm able to manage the db using phpPgAdmin. But I have yet to determine what phpPgAdmin is doing differently to connect to the db than what Kohana 3 is attempting. Bart

  • How do you reconcile IDisposable and IoC?

    - by Mr. Putty
    I'm finally wrapping my head around IoC and DI in C#, and am struggling with some of the edges. I'm using the Unity container, but I think this question applies more broadly. Using an IoC container to dispense instances that implement IDisposable freaks me out! How are you supposed to know if you should Dispose()? The instance might have been created just for you (and therefor you should Dispose() it), or it could be an instance whose lifetime is managed elsewhere (and therefor you'd better not). Nothing in the code tells you, and in fact this could change based on configuration!!! This seems deadly to me. Can any IoC experts out there describe good ways to handle this ambiguity?

  • How to produce a merged RSS feed (from DokuWiki and Serendipity)

    - by symcbean
    Hi, I've got an application developed on top of DokuWiki. I'd like to provide a 'News' page providing the latest updates from the internal RSS feed, some other feeds maintained in Serendipity and potentially other locations. Although its trivial to attach feed parsers to each one individually, I'd like to aggregate this into a single list (possibly a single RSS feed). Both the DokuWiki and Serendipity servers are not connected to the internet - so I can't use an external service for this - looking for code. Anybody got any ideas? TIA C.

  • Odd ActiveRecord model dynamic initialization bug in production

    - by qfinder
    I've got an ActiveRecord (2.3.5) model that occasionally exhibits incorrect behavior that appears to be related to a problem in its dynamic initialization. Here's the code: class Widget < ActiveRecord::Base extend ActiveSupport::Memoizable serialize :settings VALID_SETTINGS = %w(show_on_sale show_upcoming show_current show_past) VALID_SETTINGS.each do |setting| class_eval %{ def #{setting}=(val); self.settings[:#{setting}] = (val == "1"); end def #{setting}; self.settings[:#{setting}]; end } end def initialize_settings self.settings ||= { :show_on_sale => true, :show_upcoming => true } end after_initialize :initialize_settings # All the other stuff the model does end The idea was to use a single record field (settings) to persist a bunch of configuration data for this object, but allow all the settings to seamlessly work with form helpers and the like. (Why this approach makes sense here is a little out of scope, but let's assume that it does.) Net-net, Widget should end up with instance methods (eg #show_on_sale= #show_on_sale) for all the entires in the VALID_SETTINGS array. Any default values should be specified in initialize_settings. And indeed this works, mostly. In dev and staging, no problems at all. But in production, the app sometimes ends up in a state where a) any writes to the dynamically generated setters fail and b) none of the default values appear to be set - although my leading theory is that the dynamically generated reader methods are just broken. The code, db, and environment is otherwise identical between the three. A typical error message / backtrace on the fail looks like: IndexError: index 141145 out of string (eval):2:in []=' (eval):2:inshow_on_sale=' [GEM_ROOT]/gems/activerecord-2.3.5/lib/active_record/base.rb:2746:in send' [GEM_ROOT]/gems/activerecord-2.3.5/lib/active_record/base.rb:2746:inattributes=' [GEM_ROOT]/gems/activerecord-2.3.5/lib/active_record/base.rb:2742:in each' [GEM_ROOT]/gems/activerecord-2.3.5/lib/active_record/base.rb:2742:inattributes=' [GEM_ROOT]/gems/activerecord-2.3.5/lib/active_record/base.rb:2634:in `update_attributes!' ...(then controller and all the way down) Ideas or theories as to what might be going on? My leading theory is that something is going wrong in instance initialization wherein the class instance variable settings is ending up as a string rather than a hash. This explains both the above setter failure (:show_on_sale is being used to index into the string) and the fact that getters don't work (an out of bounds [] call on a string just returns nil). But then how and why might settings occasionally end up as a string rather than hash?

  • ASP.Net MVC Where do you convert from Entities to ViewModels?

    - by Pino
    Title pretty much explains it all, its the last thing I'm trying to work into our project. We are structured with a Service Library which contains a function like so. /// <summary> /// Returns a single category based on the specified ID. /// </summary> public Category GetCategory(int CategoryID) { var RetVal = _session.Single<Category>(x => x.ID == CategoryID); return RetVal; } Now Category is a Entity (We are using Entity Framework) we need to convert that to a CategoryViewModel. Now, how would people structure this? Would you make sure the service function returned a CategoryViewModel? Have the controller pull the data from the service then call another function to covnert to a view model?

  • How many SQL Server DBAs does an organization need?

    - by RickHeiges
    "How many SQL Server DBAs do we need?" - This is a question that often comes up in conversations with customers. Essentially, customers want to know if they have enough DBAs or too many. This is not a trivial question. If you do some research online via your favorite search engine, you will most likely come across numbers such as 40-65 DBs per DBA (for SQL Server). I remember finding another number relating to storage space instead of the number of DBs; the range was 3-5TB per DBA. I have had custoemrs...(read more)

  • OpenCV in Python can't scan through pixels

  • How to hide (in Thunar and Nautilus) a directory without putting a dot in its name?

    - by Ivan
    Usually Linux programs store user's settings in ~/.* directories. But unfortunately some developers (of some applications I need) do not follow this rule and don't start their settings storage folders names with a dot. This results in never-user-used folders cluttering (not the right word perhaps, as there are not many, but they annoy anyway) a home directory. Renaming them is not an option, as the applications won't find them in this case (and will create them again). Is there a way to hide a folder having no dot starting its name from being displayed in common file system browsers (I actually use Thunar of XFCE, alongside with Midnight Commander and Krusader, but wouldn't mind to know about Nautilus too).

  • How are minimum system requirements determined?

    - by Michael McGowan
    We've all seen countless examples of software that ships with "minimum system requirements" like the following: Windows XP/Vista/7 1GB RAM 200 MB Storage How are these generally determined? Obviously sometimes there are specific constraints (if the program takes 200 MB on disk then that is a hard requirement). Aside from those situations, many times for things like RAM or processor it turns out that more/faster is better with no hard constraint. How are these determined? Do developers just make up numbers that seem reasonable? Does QA go through some rigorous process testing various requirements until they find the lowest settings with acceptable performance? My instinct says it should be the latter but is often the former in practice.

  • How to manage the default Java SwingWorker thread pool?

    - by Guy Lancaster
    I've got an application that uses 2 long-running SwingWorker tasks and I've just encountered a couple of Windows computers with updated JVMs that only start one of the them. There are no errors indicated so I have to assume that the default thread pool has only a single thread and therefore the second SwingWorker object is getting queued when I try to execute it. So, (1) how do I check check how many threads are available in the default SwingWorker thread pool, and (2) how do I add threads if I'm going to need more? Anything else that I should know? This apparent single-thread thread-pool situation goes against all of my expectations. I'm setting up a ThreadPoolExecutor but this seems so wrong...

  • setIncludesSubentities: in an NSFetchRequest is broken for entities across multiple persistent store

    - by SG
    Prior art which doesn't quite address this: http://stackoverflow.com/questions/1774359/core-data-migration-error-message-model-does-not-contain-configuration-xyz I have narrowed this down to a specific issue. It takes a minute to set up, though; please bear with me. The gist of the issue is that a persistentStoreCoordinator (apparently) cannot preserve the part of an object graph where a managedObject is marked as a subentity of another when they are stored in different files. Here goes... 1) I have 2 xcdatamodel files, each containing a single entity. In runtime, when the managed object model is constructed, I manually define one entity as subentity of another using setSubentities:. This is because defining subentities across multiple files in the editor is not supported yet. I then return the complete model with modelByMergingModels. //Works! [mainEntity setSubentities:canvasEntities]; NSLog(@"confirm %@ is super for %@", [[[canvasEntities lastObject] superentity] name], [[canvasEntities lastObject] name]); //Output: "confirm Note is super for Browser" 2) I have modified the persistentStoreCoordinator method so that it sets a different store for each entity. Technically, it uses configurations, and each entity has one and only one configuration defined. //Also works! for ( NSString *configName in [[HACanvasPluginManager shared].registeredCanvasTypes valueForKey:@"viewControllerClassName"] ) { storeUrl = [NSURL fileURLWithPath:[[self applicationDocumentsDirectory] stringByAppendingPathComponent:[configName stringByAppendingPathExtension:@"sqlite"]]]; //NSLog(@"entities for configuration '%@': %@", configName, [[[self managedObjectModel] entitiesForConfiguration:configName] valueForKey:@"name"]); //Output: "entities for configuration 'HATextCanvasController': (Note)" //Output: "entities for configuration 'HAWebCanvasController': (Browser)" if (![persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:configName URL:storeUrl options:options error:&error]) //etc 3) I have a fetchRequest set for the parent entity, with setIncludesSubentities: and setAffectedStores: just to be sure we get both 1) and 2) covered. When inserting objects of either entity, they both are added to the context and they both are fetched by the fetchedResultsController and displayed in the tableView as expected. // Create the fetch request for the entity. NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; [fetchRequest setEntity:entity]; [fetchRequest setIncludesSubentities:YES]; //NECESSARY to fetch all canvas types [fetchRequest setSortDescriptors:sortDescriptors]; [fetchRequest setFetchBatchSize:20]; // Set the batch size to a suitable number. [fetchRequest setAffectedStores:[[managedObjectContext persistentStoreCoordinator] persistentStores]]; [fetchRequest setReturnsObjectsAsFaults:NO]; Here is where it starts misbehaving: after closing and relaunching the app, ONLY THE PARENT ENTITY is fetched. If I change the entity of the request using setEntity: to the entity for 'Note', all notes are fetched. If I change it to the entity for 'Browser', all the browsers are fetched. Let me reiterate that during the run in which an object is first inserted into the context, it will appear in the list. It is only after save and relaunch that a fetch request fails to traverse the hierarchy. Therefore, I can only conclude that it is the storage of the inheritance that is the problem. Let's recap why: - Both entities can be created, inserted into the context, and viewed, so the model is working - Both entities can be fetched with a single request, so the inheritance is working - I can confirm that the files are being stored separately and objects are going into their appropriate stores, so saving is working - Launching the app with either entity set for the request works, so retrieval from the store is working - This also means that traversing different stores with the request is working - By using a single store instead of multiple, the problem goes away completely, so creating, storing, fetching, viewing etc is working correctly. This leaves only one culprit (to my mind): the inheritance I'm setting with setSubentities: is effective only for objects creating during the session. Either objects/entities are being stored stripped of the inheritance info, or entity inheritance as defined programmatically only applies to new instances, or both. Either of these is unacceptable. Either it's a bug or I am way, way off course. I have been at this every which way for two days; any insight is greatly appreciated. The current workaround - just using a single store - works completely, except it won't be future-proof in the event that I remove one of the models from the app etc. It also boggles the mind because I can't see why you would have all this infrastructure for storing across multiple stores and for setting affected stores in fetch requests if it by core definition (of setSubentities:) doesn't work.
