• What is the purpose of the canonical view volume?

  - by breadjesus

  I'm currently learning OpenGL and haven't been able to find an answer to this question. After the projection matrix is applied to the view space, the view space is "normalized" so that all the points lie within the range [-1, 1]. This is generally referred to as the "canonical view volume" or "normalized device coordinates". While I've found plenty of resources telling me about how this happens, I haven't seen anything about why it happens. What is the purpose of this step?

• /manual/cache folder on my server?

  - by MrZombie

  Hi all, On our site's server, once managed by someone who's no longer with us, there's a folder named "/manual/cache" which contains txt files named+like+this, mostly using pornographic-related keywords. The content is mainly spam-like gibberish. My assumption on the matter is that it's somehow used to spam search engines, but I might be wrong, which is the reason of my question here. Any idea what it might mean/contain? As an additionnal note, the person's hiring period oddly correspond to the dates of the files, which seem to have automagically stopped being generated after the date we parted ways.

• How do I open 2 instances of the same file in notepad++ side by side with their own scrollbars in a single Notepad++ window?

  - by Qlidnaque

  I remember doing this a long time ago and have forgotten how I had done it. I like to do this when I have long html or php files to edit and I need part of the code from further down the file in a place nearer to the top, or when I want to compare different parts of the same file. There was a way to do this without opening two instances of Notepad++ and when I clicked on save, it made the saved changes in both instances of the opened file (whereas if I have 2 windows of Notepad++ opened simultaneously, it will prompt me to either update or not update the second opened instance if the first one was saved midway.)

• Move / SVMOTION Replica / Source from Datastore to another

  - by Gdriver

  Hi, I need to evacuate 2 Datastores. Now the only things on those 2 datastores are 4 replica / source machines. These are productive ones which means, there are a lot of linked clones linked to these replicas. So there is no way to recompose these ones. If I would unprotect the entity the linked clones wouldn´t work anymore right? Is there a way to move the replicas to another datastore without "killing" the linked clones?

• getJSON not working if the mvc model view controller has a parameter

  - by Paul

  I'm having an issue with a callback. I'm not even getting an error in Firebug. If I alert before and after the getjson call both alerts show but the getjson call doesn't fire. public ActionResult TestPage() { return View(); } public ActionResult LoadMapLonLats(int mapId) { //some code return Json(_myMaps); } $("#Search").click(function() { $.getJSON("LoadMapLonLats", { mapId: 73 }, loadDbMap); }); function loadDbMap(maps) { alert('m'); $.each(maps, function(i) { alert(maps[i]); }); } As long as I leave TestPage without a parameter is works. If I add a parameter to TestPage(int id) then the call back to LoadMapLonLats doesn't work. Seems odd. Of course TestPage is the page I'm loading so I need to do some work here before rendering the page. Not sure why adding a parameter to the view would break the callback to another function. //this breaks he callback to LoadMapLonLats public ActionResult TestPage(int id) { return View(); } Any ideas? Seems like this may be related, if not sorry I can post a new thread.

• Set focus on textbox in WPF from view model (C#) & wPF

  - by priyanka.sarkar

  I have a TextBox and a Button in my view. Now I am checking a condition upon button click and if the condition turns out to be false, displaying the message to the user, and then I have to set the cursor to the text box control. if (companyref == null) { Lipper.Nelson.AdminClient.Main.Views.ContactPanels.CompanyAssociation cs = new Lipper.Nelson.AdminClient.Main.Views.ContactPanels.CompanyAssociation(); MessageBox.Show("Company does not exist.", "Error", MessageBoxButton.OK, MessageBoxImage.Exclamation); cs.txtCompanyID.Focusable = true; System.Windows.Input.Keyboard.Focus(cs.txtCompanyID); } The above code is in the view model. The CompanyAssociation is the view name. But the cursor is not getting set in the TextBox.

• Is there a way to update a ViewModel in MVC2?

  - by Juvaly

  This code works: [HttpPost] public ActionResult Edit(int id, FormCollection fc) { Movie movie = ( from m in _ctx.Movie.Include("MovieActors") where m.MovieID == id select m ).First(); MovieActorViewModel movieActor = new MovieActorViewModel(movie); if (TryUpdateModel(movieActor)) { _ctx.ApplyPropertyChanges(movieActor.Movie.EntityKey.EntitySetName, movieActor.Movie); _ctx.SaveChanges(); } return View(movieActor); } However, I am not sure how to test this, and in general would much rather have the method take a typed model like: [HttpPost] public ActionResult Edit(MovieActorViewModel movieActor) Is this possible? What changes to my MovieActorViewModel class do I need to make in order to enable this? That class looks like this: public class MovieActorViewModel { public Movie Movie { get; set; } public Actor Actor { get; set; } public PublisherDealViewModel(Movie movie) { this.Movie = movie; this.Actor = ( from a in this.Movie.Actors where a.ActorID == 1 select a ).First(); } } The view is typed (inherits ViewPage) simple: <% using (Html.BeginForm()) {%> Movie Title: <%= Html.TextBoxFor(model=>model.Movie.Title) %><br/> Actor Name: <%= Html.TextBoxFor(model=>model.Actor.Name) %> <% } %>

• Why declare "private List contactInfos" without a generic ("private List <ContactInfo> contactInfos"

  - by g_imp

  In this example from the App Engine docs, why does the example declare contactInfos like this (no Generics): import javax.jdo.annotations.Element; // ... @Persistent @Element(dependent = "true") private List contactInfos; instead of like this, using a Generic: import javax.jdo.annotations.Element; // ... @Persistent @Element(dependent = "true") private List <ContactInfo> contactInfos;

• Where should 'CreateMap' statements go?

  - by jonathanconway

  I frequently use AutoMapper to map Model (Domain) objects to ViewModel objects, which are then consumed by my Views, in a Model/View/View-Model pattern. This involves many 'Mapper.CreateMap' statements, which all must be executed, but must only be executed once in the lifecycle of the application. Technically, then, I should keep them all in a static method somewhere, which gets called from my Application_Start() method (this is an ASP.NET MVC application). However, it seems wrong to group a lot of different mapping concerns together in one central location. Especially when mapping code gets complex and involves formatting and other logic. Is there a better way to organize the mapping code so that it's kept close to the ViewModel that it concerns? (I came up with one idea - having a 'CreateMappings' method on each ViewModel, and in the BaseViewModel, calling this method on instantiation. However, since the method should only be called once in the application lifecycle, it needs some additional logic to cache a list of ViewModel types for which the CreateMappings method has been called, and then only call it when necessary, for ViewModels that aren't in that list.)

• Why Does the iPad Main View Refuse to go FullScreen?

  - by dugla

  I am doing an imaging app for iPad and it requires use of the entire screen. The approach I have used on iPhone does not appear to work on iPad. In Interface Builder I have set the UIToolbar to translucent.This code echos the dimensions of the main view before and after requesting fullscreen. (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { [self.window addSubview:self.viewController.view]; NSLog(@"Hello Popover AD - application did Finish Launching With Options - viewSize: %f %f BEFORE", self.viewController.view.bounds.size.width, self.viewController.view.bounds.size.height); [self.viewController setWantsFullScreenLayout:YES]; [self.viewController.view layoutIfNeeded]; NSLog(@"Hello Popover AD - application did Finish Launching With Options - viewSize: %f %f AFTER", self.viewController.view.bounds.size.width, self.viewController.view.bounds.size.height); [self.window makeKeyAndVisible]; return YES; } This is what NSlog has to say: Hello Popover AD - application did Finish Launching With Options - viewSize: 768 1004 BEFORE Hello Popover AD - application did Finish Launching With Options - viewSize: 768 1004 AFTER Can someone please tell me what I am doing incorrectly here? Note, on iPhone I set fullscreen within the init method of the relevant ViewController. Can view resizing only be done in a ViewController? My ultimate goal is a fullscreen view nicely tucked underneath a translucent status bar and tool bar. I will retract the status/tool bars when user interaction begins in the main view. Thanks, Doug

• Android: how to tell if a view is scrolling

  - by Dave

  in iPhone, this would be simple---each view has a scrollViewDidScroll method. I am trying to find the equivalent in Android. My code works, but it isn't giving me what I want. I need to execute code the entire duration that a view is scrolling. So, even though I use OnGestureListener's onScroll method, it only fires when the finger is on the screen (it's not really named correctly---it should be called "onSlide" or "onSwipe", focusing on the gesture rather than the UI animation). It does not continue to fire if the user flicks the view and it is still scrolling for a few moments after the user lifts his finger. is there a method that is called at every step of the scroll? public class Scroll extends Activity implements OnGestureListener { public WebView webview; public GestureDetector gestureScanner; public int currentYPosition; public int lastYPosition; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); webview = new WebView(this); setContentView(webview); webview.loadUrl("file:///android_asset/Scroll.html"); gestureScanner = new GestureDetector(this); currentYPosition = 0; lastYPosition = 0; } public boolean onTouchEvent(final MotionEvent me) { return gestureScanner.onTouchEvent(me); } public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) { // I do stuff here. return true; }

• Handling one-to-many relationship with ZF partialLoop

  - by snaken

  Lets say i'm listing musical artists, each artist has basic information like Name, Age etc. stored in an artist table. They also have entries in an Albums table (album name/album cover etc), referencing the artist table using the artist id as a foreign key. I have the Model_Artist (Artist.php) file: class Model_Artist extends Zend_Db_Table_Abstract { protected $_name = 'artist'; protected $_dependentTables = array('Model_ArtistAlbums'); public function fetchArtistss() { $select = $this->select(); return $this->fetchAll($select); } } and to the Model_ArtistAlbums (ArtistAlbums.php) file class Model_ArtistAlbums extends Zend_Db_Table_Abstract { protected $_name = 'albums'; protected $_referenceMap = array( 'Artists' => array( 'columns' => 'alb_art_id', 'refTableClass' => 'Model_Artist', 'refColumns' => 'art_id' ) ); // etc } in my controller: public function indexAction() { /* THIS WORKS $art = new Model_Artist(); $artRowset = $art->find(1); $art1 = $artRowset->current(); $artalbums = $art1->findDependentRowset('Model_ArtistAlbums'); foreach($artalbums as $album){ echo $album->alb_title."<br>"; } */ $arts = new Model_Artist(); $this->view->artists = $arts->fetchArtists(); } in the view file: $this->partial()->setObjectKey('artist'); echo $this->partialLoop('admin/list-artists.phtml', $this->artists); but with this code in artists/list-artists.phtml: foreach($this->artist->findDependentRowset('albums') as $album): // other stuff endforeach; i get this error: Fatal error: Call to a member function findDependentRowset() on a non-object A var_dump of $this->artist = NULL.

• Geocoding Chinese addresses using Google Maps API in Python?

  - by Jack Low

  I have looked into Geopy and googlemaps (http://py-googlemaps.sourceforge.net/) and they both do not work for Chinese addresses. My app is stored on the Google App Engine. What I want to do is to parse a file containing addresses of restaurants in Hong Kong, and then Geocode the addresses and store the Lat and Lng in the datastore. How do I do this?

• Set initial view with SkpWriter in Google Sketchup C++ SDK

  - by Peter Olsson

  How do you set the initial view for the model in an SKP file created with the SkpWriter in Google Sketchup C++ SDK? There has been an example in an older version of the SDK. Part of the source is posted here. I'm trying to use: m_pDoc->GetModel()->SetCamera(cameraDefn); The problem is that I'm not able to create a valid atlast::sketchup::CCameraDefinition. Non of the examples in the above post works: atlast::sketchup::CCameraDefinition cameraDefn; cameraDefn.Set(atlast::geometry::CPoint3d(793.838, -1262.6, 2603.16), atlast::geometry::CPoint3d(567.977, 338.199, 398.932), atlast::geometry::CUnitVector3d(-0.112657, 0.798459, 0.591415)); and: atlast::sketchup::CCameraDefinition cameraDefn; cameraDefn.Set(atlast::geometry::CPoint3d(793.838, -1262.6, 2603.16), atlast::geometry::CPoint3d(567.977, 338.199, 398.932), atlast::geometry::CUnitVector3d(-0.112657, 0.798459, 0.591415)); In the end I want the initial view to be the view you get from pressing the icon for Zoom extents followed by the Iso icon (the other way around is also ok). Right now I would settle for creating a valid atlast::sketchup::CCameraDefinition. Any better way to achieve this in the SKP-file?
