  • deriving from NSTabViewItem

    - by Jonny
    I'm writing a Cocoa app. One dialog has 3 tabs, some of the tabs needs more loading time, so I want to load them lazily. Since each Tab is a NSTabViewItem class, so I'm trying to derive from it and overriding its view property. In the view getter method, I use a ViewController to load a view and returns out. In Debugging, I found NSTabViewItem -view method is get called correctly, but after that NSTabView tries to set Initial FirstResponder and crashed with message: * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'In -[NSTabViewItem setInitialFirstResponder:], the first responder must descend from the tab view item's view. (Item: Invalid responder: )' I tried to override the -initialFirstResponder method to return a sub-view of my loaded view, but it still crashes the same place. does anyone know how to get it work correctly? Also is it correct way to do this by deriving the NSTabViewItem? thanks! -Jonny

  • BoundingBox created from mesh to origin, making it bigger

    - by Gunnar Södergren
    I'm working on a level-based survival game and I want to design my scenes in Maya and export them as a single model (with multiple meshes) into XNA. My problem is that when I try to create Bounding Boxes(for Collision purposes) for each of the meshes, the are calculated from origin to the far-end of the current mesh, so to speak. I'm thinking that it might have something to do with the position each mesh brings from Maya and that it's interpreted wrongly... or something. Here's the code for when I create the boxes: private static BoundingBox CreateBoundingBox(Model model, ModelMesh mesh) { Matrix[] boneTransforms = new Matrix[model.Bones.Count]; model.CopyAbsoluteBoneTransformsTo(boneTransforms); BoundingBox result = new BoundingBox(); foreach (ModelMeshPart meshPart in mesh.MeshParts) { BoundingBox? meshPartBoundingBox = GetBoundingBox(meshPart, boneTransforms[mesh.ParentBone.Index]); if (meshPartBoundingBox != null) result = BoundingBox.CreateMerged(result, meshPartBoundingBox.Value); } result = new BoundingBox(result.Min, result.Max); return result; } private static BoundingBox? GetBoundingBox(ModelMeshPart meshPart, Matrix transform) { if (meshPart.VertexBuffer == null) return null; Vector3[] positions = VertexElementExtractor.GetVertexElement(meshPart, VertexElementUsage.Position); if (positions == null) return null; Vector3[] transformedPositions = new Vector3[positions.Length]; Vector3.Transform(positions, ref transform, transformedPositions); for (int i = 0; i < transformedPositions.Length; i++) { Console.WriteLine(" " + transformedPositions[i]); } return BoundingBox.CreateFromPoints(transformedPositions); } public static class VertexElementExtractor { public static Vector3[] GetVertexElement(ModelMeshPart meshPart, VertexElementUsage usage) { VertexDeclaration vd = meshPart.VertexBuffer.VertexDeclaration; VertexElement[] elements = vd.GetVertexElements(); Func<VertexElement, bool> elementPredicate = ve => ve.VertexElementUsage == usage && ve.VertexElementFormat == VertexElementFormat.Vector3; if (!elements.Any(elementPredicate)) return null; VertexElement element = elements.First(elementPredicate); Vector3[] vertexData = new Vector3[meshPart.NumVertices]; meshPart.VertexBuffer.GetData((meshPart.VertexOffset * vd.VertexStride) + element.Offset, vertexData, 0, vertexData.Length, vd.VertexStride); return vertexData; } } Here's a link to the picture of the mesh(The model holds six meshes, but I'm only rendering one and it's bounding box to make it clearer: http://www.gsodergren.se/portfolio/wp-content/uploads/2011/10/Screen-shot-2011-10-24-at-1.16.37-AM.png The mesh that I'm refering to is the Cubelike one. The cylinder is a completely different model and not part of any bounding box calculation. I've double- (and tripple-)-checked that this mesh corresponds to this bounding box. Any thoughts on what I'm doing wrong?

  • .net Listview control will only display largeIcon.

    - by Redshirt
    I'm using the RC of visual Studio 2010. Writing a .net 3.5 application. When I launch the app, the listview control only shows in LargeIcon view. This is not the view I want. I've set the View property in the designer with no success. I've even tried to explicitly set the view during runtime lvAvailableItems.View = View.Tile; Has anyone else had this issue, and if so what was your workaround.

  • Implement System.Web.Caching.Cache Object in a controller to cache specific query

    - by Julien
    Hello World! I'm Julien and I have a question is it correct to implement my caching object like this in my controller : public class HomeController : BaseController { public static Cache cachingControl = new Cache(); ... And I Use it like this : public ActionResult Home() { IndexViewData view = new IndexViewData(); view.UserId = UserId; if (cachingControl.Get("viewHome") != null) { view = (IndexViewData)cachingControl.Get("viewHome"); } else { view.allAdsList = AllAds(5000, 0); if (Request.QueryString["voirTous"] != null) view.loadGeneral(true); else view.loadGeneral(false); cachingControl.Insert("viewHome", view); } view.adsList = SetupSearch(5, false, 0); return View(view); } But When I Call this line : if (cachingControl.Get("viewHome") != null) { They trow me the error NullErrorException But I know it can be null this is why i'm put this condition to Do you have an alternative or a tips for me thank you! P.S.: I Know that the code is weird :P but I must to support it ... Julien

  • How to make ASP.Net MVC checkboxes keep state

    - by myotherme
    I have the following situation: I have a class Product that can have a confirmation from various Stations. So I have a ViewModel that holds the Product information, and a list of stations, and all the ProductStationConfirmations. public class ProductViewModel { public Product Product { get; private set; } public List<Station> Stations { get; private set; } public Dictionary<string, ProductStationConfirmation> ProductStationConfirmations { get; private set; } public ProductViewModel(int productID) { // Loads everything from DB } } In my partial view for inserting/editing I iterate over the stations to make a checkbox for each of them: <div class="editor-label"> <%= Html.LabelFor(model => model.Product.Title)%> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.Product.Title)%> <%= Html.ValidationMessageFor(model => model.Product.Title)%> </div> <fieldset> <legend>Station Confirmations</legend> <% foreach (var station in Model.Stations) { %> <div class="nexttoeachother"> <div> <%= Html.Encode(station.Name) %> </div> <div> <%= Html.CheckBox("confirm_"+station.ID.ToString(), Request["confirm_"+station.ID.ToString()] == null ? Model.ProductStationConfirmations.ContainsKey(Entities.ProductStationConfirmation.MakeHash(Model.Product.ID, station.ID)) : Request["confirm_" + station.ID.ToString()].Contains("true") ) %> </div> </div> <% } %> </fieldset> This works and I can process the Request values to store the confirmed Stations, but it is really messy. I made it this way to preserve the state of the checkboxes between round trips if there is a problem with the model (missing title, bad value for decimal, or something that can only be checked server-side like duplicate tile). I would expect that there is a nicer way to do this, I just don't know what it is. I suspect that I need to change the shape of my ViewModel to better accommodate the data, but i don't know how. I am using MVC 2.

  • How do I create a UISplitView manually?

    - by Mark
    I have an app that is going to navigate to a UISplitView (inside another view altogether) like so: - (void) switchToMyDayView { NSLog(@"Show My Day Screen"); if (self.myDayController.view.superview == nil) { if (self.myDayController == nil) { MyDayController *myController = [[MyDayController alloc] initWithNibName:@"MyDay" bundle:nil]; self.myDayController = myController; [myController release]; } [homeScreenController.view removeFromSuperview]; [self.view insertSubview:self.myDayController.view atIndex:0]; } } Which is done on the main navigation screen Now, the MyDayController has a XIB called MyDay.xib which has these items: File's Owner: MyDayController First Responder: UIResponder Split View Controller ---->Navigation Controller ---->Navigation Bar ----> Table View Controller ----> Navigation Item ---->View Controller So, I need some more components here, I need a UITableViewController and a UISplitViewControllerDelegate correct? I was going to just implement these protocols in my MyDayController, is this sort of standard? So, after the code above, I get an error: -[UIViewController _loadViewFromNibNamed:bundle:] loaded the "MyDay" nib but the view outlet was not set. so, how can I fix it using the UISplitViewController? I know that the UISplitViewController has a view property, but I cannot use it/connect it up in IB can I? Thanks a lot Mark

  • Pattern for sharing data between views (MVP or MVVM)

    - by Dovix
    What is a good pattern for sharing data between related views?. I have an application where 1 form contains many small views, each views behaves independently from each other more or less (they communicate/interact via an event bus). Every so often I need to pass the same objects to the child views. Sometimes I need this same object to be passed to a child view and then the child passes it onto another child itself contains. What is a good approach to sharing this data between all the views contained within the parent form (view) ? I have looked into CAB and their approach and every "view" has a "root work item" this work item has dictionary that contains a shared "state" between the views that are contained. Is this the best approach? just a shared dictionary all the views under a root view can access? My current approach right now is to have a function on the view that allows one to set the object for that view. Something like view.SetCustomer(Customer c); then if the view contains a child view it knows to set it on the child view ala: this.childview1.SetCustomer(c); The application is written in C# 3.5, for winforms using MVP with structure map as a IoC/DI provider.

  • How to switch to user perspective in Blender

    - by Cyanophage
    I've just started using Blender (v2.63) for the first time. I have used a lot of 3d modelling programs in the past but Blender's controls seem to be set up differently and it's taking a while to get used to it. The thing that is really bugging me at the moment is switching from user perspective to front/side/top views. I have my view in perspective mode and I want to switch to front view in orthographic mode and then switch back to the view I had before. It seems that the only way is to press numpad-0 to go to camera view, rotate the screen a bit to get rid of the annoying black outline and then switch it back to perspective mode. Then sometimes when I go back to front view it's in perspective mode which is annoying as you never want front view in perspective, only orthographic mode. My question: Is there a way I can be in my user view in perspective mode, switch to front/side/top views in orthographic mode and then switch back to where I was before in my user mode and be back in perspective mode?

  • SharePoint 2010 Data Retrival Techinques

    - by Jayant Sharma
    In SharePoint, we have two options to perform CRUD operation.1. using server side code2. using client side codeusing server side code, we have 1. CAML2. LINQusing client side code, we have 1. Client Object Model    1.1.      Managed Client Object Model     1.2.     Silverlight Client Object Model    1.3.     ECMA Client Object Model2. SharePoint Web Services3. ADO Data Service (based on REST Web Services)4. Using RPC Call (owssvr.dll)Which and when these options are used depend upon requirements. Every options are certain advantages and disadvantages. So, before start development of any new sharepoint project, it is important to understand the limitations of different methods.Server Object Model is used when our application is host on the same server on which sharepoint is installed. while Client Side code is used to access sharepoint from client system. In SharePoint 2010 specially Client Object Model (COM) are introduced to perform the sharepoint operations from client system. Advantage of CAML:    -  It is fast.    -  Can be use it from all kind of technology like Silverlight, or Jquery    -  You can use U2U CAML Query builder to generate CAML Query.Disadvantage Of CAML:    - Error Prone, as we can detect the error only at runtimeAdvantage of LINQ:    -  Object Oriented technique (Object Relation Model)    -  LINQ  to SharePoint provider are working with Strongly Type List Item Objects, So intellisence are present at runtime    -  No need of knowledge of CAML    -  Less Error Prone as it as it uses C# syntex.    -  You can compare two Fields of SharePoint ListDisadvantage Of LINQ:    -  List Attachment is not supported in SPMetal Tool    -  Created By, Created, Modified and Modified By Fields are not created by SPMetal Tool.    -  Custom fields are not created by SPMetal Tools    -  External Lists are not supported    -  Though at backend LINQ genenates CAML Query so it is slower than directly using CAML in Code.  Advantage of Client Object Model    -  Used to access sharepoint from client system    -  No WebServer is required at Client End    - Can use Silverlight and JavaScripts to make better and fast User experienceDisadvantage of Client Object Model    -  You cannot use RunwithEleveatedPrivilege    - Cross Site Collection query are not possible    - Lesser API's are availableADO.Net Data Services:    -  Only List based operations are possible, other type of operations are not possible.SharePoint Web Services and RPC Call:    - Previously it was used in SharePoint 2007 but after the introduction  of Client Object Model,  Microsoft recommends not to use Web Services to fetch data from SharePoint. In SharePoint 2010 it is avaliable only for backward compatibility.Ref: http://msdn.microsoft.com/en-us/library/ee539764Jayant Sharma

  • Blender DirectX exporter to Panda3D

    - by jakebird451
    I have been experimenting with Panda3D lately. I have a character made in Blender with various bones and currently with one animation that I wish to export to a *.x format for Panda3D. My current attempt was to export the model was to first export with bones [Armatures] by checking the "Export Armatures" button in the export menu (file name: char.x). Thanks to the *.x file format, I read the file and it seems to have the same bone structure format as the model (with parenting and matrix positional data). The second export was selecting Animations - Full Animation to provide just the animation (file name: char_idle.x). The models exported just fine. I am not sure about the animation yet, but the file seems to be just fine. This is my code for loading the model into python & Panda3D: self.model = Actor("char.x",{"char_idle.x"}) When I run the program the command line provides a couple of errors, the main errors of interest are: :Actor(warning): char.x is not a character! and ... File "C:\Panda3D-1.8.0\direct\actor\Actor.py", line 284, in __init__ if (type(anims[anims.keys()[0]])==type({})): AttributeError: 'set' object has no attribute 'keys' The first error is the most interesting to me. The model works if I leave the animation dictionary blank. With no animations loaded the character appears in its un-animated T position, however the actor warning still shows up. The character should include the various bones when I exported the model right? I am not that experienced with blender, I'm just a programmer. So if the problem lies in blender please try to keep that in mind when posting a reply. I'll try my best to keep up. I also tried to print out the bone structure without any animations loaded and it provides a similar error with the line print self.model.listJoints(): File "C:\Panda3D-1.8.0\direct\actor\Actor.py", line 410, in listJoints Actor.notify.error("no part named: %s" % (partName)) File "C:\Panda3D-1.8.0\direct\directnotify\Notifier.py", line 132, in error raise exception(errorString) StandardError: no part named: modelRoot I really hope it is a simple exporting fix.

  • Shoulda: How would I use an instance variable outside of a setup or should block?

    - by TheDeeno
    I'm trying to do something like the following: @special_attributes = Model.new.methods.select # a special subset @special_attributes.each do |attribute| context "A model with #{attribute}" setup do @model = Model.new end should "have some special characteristic" assert @model.method(attribute).call end end end However, @special_attributes is out of scope when running the unit tests, leaving me with a nil object on line 2. I can't figure out where to define it to bring it in scope. Any thoughts?

  • Ensure your view and function meta data is upto date.

    - by simonsabin
    You will see if you use views and functions that SQL Server holds the rowset metadata for this in system tables. This means that if you change the underlying tables, columns and data types your views and functions can be out of sync. This is especially the case with views and functions that use select * To get the metadata to be updated you need to use sp_refreshsqlmodule. This forces the object to be “re run” into the database and the meta data updated. Thomas mentioned sp_refreshview which is a...(read more)

  • certain Smarty tags don't work in OpenX templates

    - by mikez302
    I am on a team that is developing an OpenX plugin, and I am responsible for the UI. I noticed that if I use certain Smarty tags in my template, the app doesn't work and I see an error message, similar to this: Plugin by name 'Html_select_date' was not found in the registry; used paths: default_views_helpers_: /openx/www/admin/plugins/myApp/application/modules/default/views/helpers/ OX_OXP_UI_View_Helper_: /openx/www/admin/plugins/myApp/application/../library/OX/OXP/UI/View/Helper/ OX_UI_View_Helper_: /openx/www/admin/plugins/myApp/application/../library/OX/UI/View/Helper/ Zend_View_Helper_: Zend/View/Helper/ (stack trace) The stack trace looks like this: #0 /openx/www/admin/plugins/myApp/library/Zend/View/Abstract.php(1117): Zend_Loader_PluginLoader-load('Html_select_dat...') #1 /openx/www/admin/plugins/myApp/library/Zend/View/Abstract.php(568): Zend_View_Abstract-_getPlugin('helper', 'html_select_dat...') #2 /openx/www/admin/plugins/myApp/library/OX/UI/Smarty/SmartyWithViewHelper.php(25): Zend_View_Abstract-getHelper('html_select_dat...') #3 /openx/var/templates_compiled/%2Fdefault%2Fviews%2Fscripts%2Findex%2Fview-reports.html^%%E8^E80^E80B56F2%%view-reports.html.php(38): OX_UI_Smarty_SmartyWithViewHelper-callViewHelper('html_select_dat...', Array) #4 /openx/lib/smarty/Smarty.class.php(1274): include('/openx...') #5 /openx/www/admin/plugins/myApp/library/OX/UI/View/SmartyView.php(103): Smarty-fetch('/openx...') #6 /openx/www/admin/plugins/myApp/library/Zend/View/Abstract.php(832): OX_UI_View_SmartyView-_run('/openx...') #7 /openx/www/admin/plugins/myApp/library/OX/UI/View/SmartyView.php(151): Zend_View_Abstract-render('index/view-repo...') #8 /openx/www/admin/plugins/myApp/library/OX/UI/View/Helper/WithViewScript.php(23): OX_UI_View_SmartyView-render('index/view-repo...') #9 /openx/www/admin/plugins/myApp/application/modules/default/views/helpers/ViewReports.php(5): OX_UI_View_Helper_WithViewScript::renderViewScript('index/view-repo...', Array) #10 /openx/www/admin/plugins/myApp/application/modules/default/controllers/IndexController.php(98): Default_Views_Helpers_ViewReports-renderPage() #11 /openx/www/admin/plugins/myApp/library/Zend/Controller/Action.php(512): IndexController-viewReportsAction() #12 /openx/www/admin/plugins/myApp/library/Zend/Controller/Dispatcher/Standard.php(288): Zend_Controller_Action-dispatch('viewReportsActi...') #13 /openx/www/admin/plugins/myApp/library/Zend/Controller/Front.php(945): Zend_Controller_Dispatcher_Standard-dispatch(Object(Zend_Controller_Request_Http), Object(Zend_Controller_Response_Http)) #14 /openx/www/admin/plugins/myApp/application/bootstrap.php(117): Zend_Controller_Front-dispatch() #15 /openx/www/admin/plugins/myApp/public/index.php(7): require('/openx...') #16 {main} This does not happen with all Smarty tags. For example, I can use {if}, {foreach}, or {assign} tags without any problems. But whenever I try to use {html_select_date}, {html_image}, or {html_table}, I get the errors. In case this matters, the programmer who is designing the plugin copied the openXWorkflow plugin and made some changes. I noticed that the openXWorkflow plugin has a file (openx/plugins_repo/openXWorkflow/www/admin/plugins/openXWorkflow/library/OX/UI/Smarty/SmartyCompilerWithViewHelper.php) with a class that overrides the default Smarty compiler, supposedly with the ability to compile shorthands for calling ZF view helpers. That file has a list of Smarty functions, but the list is incomplete. If I add the functions to the list, or simply delete the file, my template works fine, but I don't like to change library files. It may make the app hard to maintain, and I don't know if it will mess up something else. The file has the comment "There is no easy access to the list of Smarty's built-in functions so we need to list them here. HTML-specific functions are not included as we cover HTML generation separately.", so it seems like certain Smarty functions may be disabled on purpose for some reason. Will anything bad happen if I try to use them? If, for example, I want to use the {html_select_date} tag in my template, how would I go about doing that? Keep in mind that much of this stuff is new and unfamiliar to me. This is my first time ever using OpenX or Smarty, and I only have a little bit of experience with the Zend framework. Please let me know if we are using the wrong approach.

  • Nested Model binding in ASP.NET MVC2. fields_for from rails equivalent

    - by dagda1
    Hi, I am looking for some examples of how to do model binding in ASP.NET MVC2 for COMPLEX objects. All the exmples I can find are of simple objects with no child collections or child objects. If I have an Expense object with a child ExpensePayment object. In rails, child objects are rendered with the HTML name attributes like this: expense[expense_payment][net] Rails uses fields_for to render child objects. How can I accomplish something similar in ASP.NET MVC2? Cheers Paul

  • What is the best way to handle autorotation with multiple subview?

    - by thangnguyen
    I am learning and programing an application. I do this project based on what I learned from the book Beginning iphone 3 development. I have two main questions here: I would like to create a multi utility application so I need multiple-view. I have a main view controller which will control switching between views. In this example I have two views A and B. I have 2 view controller A and B which will handles all of events on these 2 views. I have 2 nib files viewA.xib and viewB.xib. One of the uitility is reading PDF. So I create another class which handle the PDF file which can load a PDF page call PDFview. From Interface Builder, I selected class identity for view of the viewB.xib as PDFView class. The result is I can switching between View A and view B. View B will display the content of the PDF page. I am not sure if my solution is right or wrong but now I don't know how to handle the autorotation. The rotation will active the view controller B. But the PDFView handle how to display the PDF on the View. Could you please tell me how I should handle this in a right way? Second question: Should I create the subview automatically? In case I need to do the swipe page animation, how can I do that? I think that I need to load another subview so I can do the animation when swap view. But I think this solution will waste the resource. I can just load another page of the PDF, but in this case I don't know how to use animation? Please tell me how I should solve this? I highly appreciate your time reading and answering my question. Thang Nguyen

  • Adding a generic image field onto a ModelForm in django

    - by Prairiedogg
    I have two models, Room and Image. Image is a generic model that can tack onto any other model. I want to give users a form to upload an image when they post information about a room. I've written code that works, but I'm afraid I've done it the hard way, and specifically in a way that violates DRY. Was hoping someone who's a little more familiar with django forms could point out where I've gone wrong. Update: I've tried to clarify why I chose this design in comments to the current answers. To summarize: I didn't simply put an ImageField on the Room model because I wanted more than one image associated with the Room model. I chose a generic Image model because I wanted to add images to several different models. The alternatives I considered were were multiple foreign keys on a single Image class, which seemed messy, or multiple Image classes, which I thought would clutter my schema. I didn't make this clear in my first post, so sorry about that. Seeing as none of the answers so far has addressed how to make this a little more DRY I did come up with my own solution which was to add the upload path as a class attribute on the image model and reference that every time it's needed. # Models class Image(models.Model): content_type = models.ForeignKey(ContentType) object_id = models.PositiveIntegerField() content_object = generic.GenericForeignKey('content_type', 'object_id') image = models.ImageField(_('Image'), height_field='', width_field='', upload_to='uploads/images', max_length=200) class Room(models.Model): name = models.CharField(max_length=50) image_set = generic.GenericRelation('Image') # The form class AddRoomForm(forms.ModelForm): image_1 = forms.ImageField() class Meta: model = Room # The view def handle_uploaded_file(f): # DRY violation, I've already specified the upload path in the image model upload_suffix = join('uploads/images', f.name) upload_path = join(settings.MEDIA_ROOT, upload_suffix) destination = open(upload_path, 'wb+') for chunk in f.chunks(): destination.write(chunk) destination.close() return upload_suffix def add_room(request, apartment_id, form_class=AddRoomForm, template='apartments/add_room.html'): apartment = Apartment.objects.get(id=apartment_id) if request.method == 'POST': form = form_class(request.POST, request.FILES) if form.is_valid(): room = form.save() image_1 = form.cleaned_data['image_1'] # Instead of writing a special function to handle the image, # shouldn't I just be able to pass it straight into Image.objects.create # ...but it doesn't seem to work for some reason, wrong syntax perhaps? upload_path = handle_uploaded_file(image_1) image = Image.objects.create(content_object=room, image=upload_path) return HttpResponseRedirect(room.get_absolute_url()) else: form = form_class() context = {'form': form, } return direct_to_template(request, template, extra_context=context)

  • Unrecognised selector sent to instance uitableview

    I'm getting error: Unrecognised selector sent to instance, upon inspection, I see there is an issue in this section of code, and more specifically: [self.tableView insertSubview:ovController.view aboveSubview:self.parentViewController.view]; - (void) searchBarTextDidBeginEditing:(UISearchBar *)theSearchBar { if(searching) return; //Add the overlay view. ovController = [[OverlayViewController alloc] initWithNibName:@"OverlayView" bundle:[NSBundle mainBundle]]; CGFloat yaxis = self.navigationController.navigationBar.frame.size.height; CGFloat width = self.view.frame.size.width; CGFloat height = self.view.frame.size.height; //Parameters x = origion on x-axis, y = origon on y-axis.
