  • Writing an unthemed view while still using Orchard shapes and helpers

    - by Bertrand Le Roy
    This quick tip will show how you can write a custom view for a custom controller action in Orchard that does not use the current theme, but that still retains the ability to use shapes, as well as zones, Script and Style helpers. The controller action, first, needs to opt out of theming: [Themed(false)] public ActionResult Index() {} .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } Then, we still want to use a shape as the view model, because Clay is so awesome: private readonly dynamic _shapeFactory; public MyController(IShapeFactory shapeFactory) { _shapeFactory = shapeFactory; } [Themed(false)] public ActionResult Index() { return View(_shapeFactory.MyShapeName( Foo: 42, Bar: "baz" )); } As you can see, we injected a shape factory, and that enables us to build our shape from our action and inject that into the view as the model. Finally, in the view (that would in Views/MyController/Index.cshtml here), just use helpers as usual. The only gotcha is that you need to use “Layout” in order to declare zones, and that two of those zones, Head and Tail, are mandatory for the top and bottom scripts and stylesheets to be injected properly. Names are important here. @{ Style.Include("somestylesheet.css"); Script.Require("jQuery"); Script.Include("somescript.js"); using(Script.Foot()) { <script type="text/javascript"> $(function () { // Do stuff }) </script> } } <!DOCTYPE html> <html> <head> <title>My unthemed page</title> @Display(Layout.Head) </head> <body> <h1>My unthemed page</h1> <div>@Model.Foo is the answer.</div> </body> @Display(Layout.Tail) </html> Note that if you define your own zones using @Display(Layout.SomeZone) in your view, you can perfectly well send additional shapes to them from your controller action, if you injected an instance of IWorkContextAccessor: _workContextAccessor.GetContext().Layout .SomeZone.Add(_shapeFactory.SomeOtherShape()); Of course, you’ll need to write a SomeOtherShape.cshtml template for that shape but I think this is pretty neat.

  • UINavigationController inside tabbar loading a child root view

    - by Doug
    Hi guys, Firstly i'll preface by saying that i am a complete Cocoa touch/objective c noob (.Net dev having a dabble) I have searched on Google as well as here but cannot seem to find an easy solution. I have a UItabbarcontroller view with a UINavigationController inside its first tab I have the root view for this UINavigationController stored in a seperate class and NIB as i am trying to seperate the data viewing from the data loading (i'm going to reuse the table list in multiple places in my database) and simply pass the root view its data using a loading method and have it take it from there. What i want to happen: App loads and loads the first view of the tab bar (A UINavigationController) The UINavigationController inside the first view loads a root view (a UIViewController with a table view) and sets its title The UINavigationController loads the data from a web service and parses it The UINavigationController sends the data to a loading method inside the UIViewController Am i thinking about this completely wrongly? What currently happens: the first tab bar loads with an empty uinavigationcontroller (no table view) the data methods fire and get the webservice data this child view gets sent its data using the loading method the tableview delegate events fail to fire inside the child view telling it to load the data into the table I just can't seem how to load my second view inside the root view of the navigation controller and then send it my data?

  • How can I programmatically add more than just one view object to my view controller?

    - by BeachRunnerJoe
    I'm diving into iPhone OS development and I'm trying to understand how I can add multiple view objects to the "Left/Root" view of my SplitView iPad app. I've figured out how to programmatically add a TableView to that view based on the example code I found in Apple's online documentation... RootViewController.h @interface RootViewController : UITableViewController <NSFetchedResultsControllerDelegate, UITableViewDelegate, UITableViewDataSource> { DetailViewController *detailViewController; UITableView *tableView; NSFetchedResultsController *fetchedResultsController; NSManagedObjectContext *managedObjectContext; } RootViewController.m - (void)loadView { UITableView *newTableView = [[UITableView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame] style:UITableViewStylePlain]; newTableView.autoresizingMask = UIViewAutoresizingFlexibleHeight|UIViewAutoresizingFlexibleWidth; newTableView.delegate = self; newTableView.dataSource = self; [newTableView reloadData]; self.view = newTableView; [newTableView release]; } but there are a few things I don't understand about it and I was hoping you veterans could help clear up some confusion. In the statement self.view = newTableView, I assume I'm setting the entire view to a single UITableView. If that's the case, then how can I add additional view objects to that view alongside the table view? For example, if I wanted to have a DatePicker view object and the TableView object instead of just the TableView object, then how would I programmatically add that? Referencing the code above, how can I resize the table view to make room for the DatePicker view object that I'd like to add? Thanks so much in advance for your help! I'm going to continue researching these questions right now.

  • Scroll view to bottom while keyboard is hiding

    - by Manu
    Hi! I'm using a scroll view to move my view and show certain text fields (that otherwise would be hidden) when the keyboard shows. I basically resize the scroll view to make room for the keyboard, and then scroll up the view smoothly with "scrollRectToVisible", which works perfectly. After that, I can scroll and edit the rest of the text fields without lowering the keyboard, which is what I intend. The problem comes when I want to hide the keyboard again. I have been able to lower the keyboard and scroll down the view to its original position without a problem, but I have been unable to make that transition smooth. At the moment I use the following: - (void)keyboardWillHide: (NSNotification *)notif { CGRect topRect = CGRectMake(0, 0, 1, 1); [scrollview scrollRectToVisible:topRect animated:YES]; scrollview.frame = CGRectMake(0, 0, scrollviewWidth, scrollviewHeight); } I create a CGRect at the top, which I then move into view with "scrollRectToVisible". That works fine and commences the scrolling right when the keyboard is hiding (I use "keyboardWillHide" and not "keyboardDidHide" because the scroll view frame is still missing its lower part). The problem comes when I resize the scroll view frame back to its original dimensions (which I need to do), because then the scrolling is interrupted and the view drops to the bottom suddenly (as there is nothing else to scroll). This causes a glitch, which is why I cannot complete the transition smoothly. Any ideas on how could I lower the keyboard while scrolling the view down smoothly? Should I be scrolling up a bigger view, instead of resizing it? That way I would not have to restore the scroll view frame dimensions when lowering the keyboard, or would I? Thanks very much in advance!

  • why need select privileges on *.* to use view?

    - by profy
    I have a problem using view with MySQL server 5.0 (5.0.92) I cannot use view with a user granted like that : GRANT USAGE ON *.* TO 'testuser'@'' IDENTIFIED BY PASSWORD '**********'; GRANT ALL PRIVILEGES ON `testuser`.* TO 'testuser'@''; I can create view, but when I try to select in, I have this messages : ERROR 1356 (HY000): View 'testuser.v' references invalid table(s) or column(s) or function(s) or definer/invoker of view lack rights to use them I need to "GRANT SELECT ON . TO 'testuser'@''" to make select working on the view. Why ? Do you know a solution to use VIEW's without the select privileges on . ? Thanks a lots for your answers.

  • View HTML Tags and Webpage Combined in Firefox

    - by Asian Angel
    Do you want an easier way to see a webpage’s html tags without viewing the source code in a separate window? Now you can view the webpage and tags combined in the same window using the X-Ray extension for Firefox. Before Usually if you want to see the source code behind a webpage you have to view it in a separate window. If you are only interested in a specific section then you have to search through the entire set of code just to find what you are looking for. After The X-Ray extension will let you see the document’s tags (including class and ID names) “side by side” with the webpage in the same tab. You can use either the context menu or the tools menu to access the X-Ray command. Here is the same webpage section shown in the first screenshot above. It may look a little odd at first until you get used to seeing both together. Note: You can return the webpage to its’ normal view by either clicking on the X-Ray command again or refreshing the page. The code for part of the sidebar on the same webpage… Followed by one of the sets of links at the end. Looking at another example suppose you are interested in how part of the main feed is set up. Being able to see how a particular element is set up directly in the webpage is certainly better than searching through the entire page of code. Conclusion If you design webpages and want an easy way to see how someone else’s website is coded then you may want to give this extension a try.

  • Given the presentation model pattern, is the view, presentation model, or model responsible for adding child views to an existing view at runtime?

    - by Ryan Taylor
    I am building a Flex 4 based application using the presentation model design pattern. This application will have several different components to it as shown in the image below. The MainView and DashboardView will always be visible and they each have corresponding presentation models and models as necessary. These views are easily created by declaring their MXML in the application root. <s:HGroup width="100%" height="100%"> <MainView width="75% height="100%"/> <DashboardView width="25%" height="100%"/> </s:HGroup> There will also be many WidgetViewN views that can be added to the DashboardView by the user at runtime through a simple drop down list. This will need to be accomplished via ActionScript. The drop down list should always show what WidgetViewN has already been added to the DashboardView. Therefore some state about which WidgetViewN's have been created needs to be stored. Since the list of available WidgetViewN and which ones are added to the DashboardView also need to be accessible from other components in the system I think this needs to be stored in a Model object. My understanding of the presentation model design pattern is that the view is very lean. It contains as close to zero logic as is practical. The view communicates/binds to the presentation model which contains all the necessary view logic. The presentation model is effectively an abstract representation of the view which supports low coupling and eases testability. The presentation model may have one or more models injected in in order to display the necessary information. The models themselves contain no view logic whatsoever. So I have a several questions around this design. Who should be responsible for creating the WidgetViewN components and adding these to the DashboardView? Is this the responsibility of the DashboardView, DashboardPresentationModel, DashboardModel or something else entirely? It seems like the DashboardPresentationModel would be responsible for creating/adding/removing any child views from it's display but how do you do this without passing in the DashboardView to the DashboardPresentationModel? The list of available and visible WidgetViewN components needs to be accessible to a few other components as well. Is it okay for a reference to a WidgetViewN to be stored/referenced in a model? Are there any good examples of the presentation model pattern online in Flex that also include creating child views at runtime?

  • View the Real Links Behind Shortened URLs in Chrome

    - by Asian Angel
    When you encounter shortened URLs there is always that worry in the back of your mind about where they really lead to. Now you can get a “sneak peak” at the real links behind those URLs with the View Thru extension for Google Chrome. The URL Shortening services officially supported at this time are: bit.ly, cli.gs, ff.im, goo.gl, is.gd, nyti.ms, ow.ly, post.ly, su.pr, & tinyurl.com. Before When you encounter a shortened URL you are pretty much on your own in deciding whether to trust that link or not. It would really be nice if you could just hover your mouse over those links and know where they will lead ahead of time. After Once you have the extension installed you are ready to access that link viewing goodness. Please note that you will need to reload any pages that were open prior to installing the extension. For our first example we chose a shortened URL from “bit.ly”. As you can see the entire link behind the shortened URL is displayed very nicely…no hidden surprises there! Note: There are no options to worry with for the extension. Another perfect result for the “goo.gl URL” shown below. View Thru will certainly remove a lot of the stress related to clicking on shortened URLs. Bonus Find Just out of curiosity we looked for a shortened URL not listed as being officially supported at this time. We found one with the “http://nyti.ms/” domain and View Thru showed the link perfectly…so be sure to give it a try on other services too. Conclusion If you worry about where a shortened URL will really lead you then the View Thru extension can help alleviate that stress.

  • Compute directional light frustum from view furstum points and light direction

    - by Fabian
    I'm working on a friends engine project and my task is to construct a new frustum from the light direction that overlaps the view frustum and possible shadow casters. The project already has a function that creates a frustum for this but its way to big and includes way to many casters (shadows) which can't be seen in the view frustum. Now the only parameter of this function are the normalized light direction vector and a view class which lets me extract the 8 view frustum points in world space. I don't have any additional infos about the scene. I have read some of the related Questions here but non seem to fit very well to my problem as they often just point to cascaded shadow maps. Sadly i can't use DX or openGl functions directly because this engine has a dedicated math library. From what i've read so far the steps are: Transform view frustum points into light space and find min/max x and y values (or sometimes minima and maxima of all three axis) and create a AABB using the min/max vectors. But what comes after this step? How do i transform this new AABB back to world space? What i've done so far: CVector3 Points[8], MinLight = CVector3(FLT_MAX), MaxLight = CVector3(FLT_MAX); for(int i = 0; i<8;++i){ Points[i] = Points[i] * WorldToShadowMapMatrix; MinLight = Math::Min(Points[i],MinLight); MaxLight = Math::Max(Points[i],MaxLight); } AABox box(MinLight,MaxLight); I don't think this is the right way to do it. The near plain probably has to extend into the direction of the light source to include potentional shadow casters. I've read the Microsoft article about cascaded shadow maps http://msdn.microsoft.com/en-us/library/windows/desktop/ee416307%28v=vs.85%29.aspx which also includes some sample code. But they seem to use the scenes AABB to determine the near and far plane which I can't since i cant access this information from the funtion I'm working in. Could you guys please link some example code which shows the calculation of such frustum? Thanks in advance! Additional questio: is there a way to construct a WorldToFrustum matrix that represents the above transformation?

  • iPhone landscape navigation back action shows vertical view transition?

    - by Code Shogun
    I have a regular UINavigationController and I push a series of UIViewController into the stack. The view transition for push controller is horizontal animation transition: [self.navigationController pushViewController:controller animated:YES]; However, when I press the Back button on the navigation bar, the view transition animation is vertical (vertically dropping down the previous controller/view). I don't seem to find any way to make this horizontal. This happens only in Landscape mode. Portrait mode the transition all happens as horizontal flip transition. Can anyone shed any light on this? Thanks

  • Spark View Engine: How to set default master page name?

    - by Dave
    I use Spark View Engine with nested master pages. I have Application.spark which defines the basic layout of the website. Then there are several other masters which themselves use Application.spark as master page (Default.spark, SinlgeColumn.spark, Gallery.spark, ...) If no master page is specified in a view file, then automatically Application.spark is choosen by the Spark View Engine. Since almost all my pages use "Default.spark" as master, is there a way to configure this globally? The other possibilities would be: Set the master in each spark file individually <use master="Default" />. But that's really annoying. Rename my master files (Default.spark <- Application.spark) but that really doesn't make any sense in naming.

  • What's the best way to check if the view is visible on the window?

    - by bhups
    What's the best way to check if the view is visible on the window? I have a CustomView which is part of my SDK and anybody can add CustomView to their layouts. My CustomView is taking some actions when it is visible to the user periodically. So if view becomes invisible to the user then it needs to stop the timer and when it becomes visible again it should restart its course. But unfortunately there is no certain way of checking if my CustomView becomes visible or invisible to the user. There are few things that I can check and listen to: onVisibilityChange //it is for view's visibility change, and is introduced in new API 8 version so has backward compatibility issue onWindowVisibilityChange //but my CustomView can be part of a ViewFlipper's Views so it can pose issues onDetachedFromWindows //this not as useful onWindowFocusChanged //Again my CustomView can be part of ViewFlipper's views. So if anybody has faced this kind of issues please throw some light.

  • Can I include a view in Kohana 3 that is not within `application/views`?

    - by alex
    I am building a staff area for a website, which is completely different to the main brochure style site. I have 2 Kohana systems setup. I realise they can both share the same system and modules folder. Now, with the second one, I want to make the main template view a view in a different folder. I tried this in my base controller $this->template = DOCROOT . '../~new2/application/views/template.php'; But Kohana is looking for it in its own views folder as evident by the error I received. I even put a var_dump(file_exists($this->template)); // true to be sure it was finding the correct file. Is there a way to add a template file that is not within the views folder, without hacking the core Kohana code (and if I'm lucky not extending and overloading the view class).

Does anyone know if it's possible? Thanks!

  • Google Earth 6–It’s All About Trees & Better Street View

    - by Gopinath
    The latest version of Google Earth is all about viewing 3D models of trees that we can see as we walk through the streets in Google Earth and integrated street views. Tech Crunch says ..trees are obviously a hugely important part of the Earth. To get them into Google Earth, the search giant has made 3D models of over 50 different species of trees. And they’ve included over 80 million of them in various places around the world including Athens, Berlin, Chicago, New York City, San Francisco, and Tokyo. The other big addition to this latest version of Google Earth is Integrated Street View. To be clear, Google has had a form of Street View in Google Earth since 2008, but now it’s fully a part of the experience. This means that you can go all the way from space, right down to Street View seamlessly. Check the embedded video to know more about Google Earth 6 features This article titled,Google Earth 6–It’s All About Trees & Better Street View, was originally published at Tech Dreams.

  • How to get Passive FTP Working Through an Iptables Firewall?

    - by user1133248
    I have an iptables firewall running on a Fedora Linux server that is basically being used as a firewall router and OpenVPN server. That's it. We have been using the same iptables firewall code for YEARS. I did make some changes on 21 December to re-route a mySQL port, but given what has happened I've completely backed those changes out. Sometime after those changes were made and backed out passive FTP, served from a vsftpd process, stopped working. We use a passive ftp client to FLING (that's the name of the ftp client running under Windows! :-) ) images from our remote telescopes to our server. I believe it is something in the firewall code because I can drop the firewall and the FTP file transfer (and connecting to the ftp site with Internet Explorer to see the file list) works. When I raise the iptables firewall, it stops working. Again, this is code that we'd been using for years. However, I felt that maybe there was something I missed, so we had a .bak file from 2009 that I used. Same behavior, passive ftp does not work. So, I went and rebuilt the firewall code line by line to see what line was causing the problem. Everything worked until I put the line -A FORWARD -j DROP in very near the end. Of course, if I am correct, this is the line that basically "turns on" the firewall, saying drop everything except for the exceptions I've made above. However, this line has been in the iptables code probably since 2003. So, I'm at the end of my rope, and I still can't figure out why this has stopped working. I guess I need an expert on iptables configuration. Here is the iptables code (from iptables-save) with comments. # Generated by iptables-save v1.3.8 on Thu Jan 5 18:36:25 2012 *nat # One of the things that I remain ignorant about is what these following three lines # do in both the nat tables (which we're not using on this machine) and the following # filter table.

  • Panning with the OpenGL Camera / View Matrix

    - by Pris
    I'm gonna try this again I've been trying to setup a simple camera class with OpenGL but I'm completely lost and I've made zero progress creating anything useful. I'm using modern OpenGL and the glm library for matrix math. To get the most basic thing I can think of down, I'd like to pan an arbitrarily positioned camera around. That means move it along its own Up and Side axes. Here's a picture of a randomly positioned camera looking at an object: It should be clear what the Up (Green) and Side (Red) vectors on the camera are. Even though the picture shows otherwise, assume that the Model matrix is just the identity matrix. Here's what I do to try and get it to work: Step 1: Create my View/Camera matrix (going to refer to it as the View matrix from now on) using glm::lookAt(). Step 2: Capture mouse X and Y positions. Step 3: Create a translation matrix mapping changes in the X mouse position to the camera's Side vector, and mapping changes in the Y mouse position to the camera's Up vector. I get the Side vector from the first column of the View matrix. I get the Up vector from the second column of the View matrix. Step 4: Apply the translation: viewMatrix = glm::translate(viewMatrix,translationVector); But this doesn't work. I see that the mouse movement is mapped to some kind of perpendicular axes, but they're definitely not moving as you'd expect with respect to the camera. Could someone please explain what I'm doing wrong and point me in the right direction with this camera stuff?

  • Problem dismissing multiple modal view controllers

    - by Sheehan Alam
    I am having trouble getting my modal view controllers to display properly. I have a parent view controller that is the delegate for modal view A. In modal view A I am presenting modal view B, and having the delegate dimiss modal view A. When modal view B appears it seems to display but the screen dims, and the UI locks up, but the app doesn't crash. I set animation settings to NO and I am still getting the same issue.

  • Passing a ManagedObjectContext to a second view

    - by amo
    I'm writing my first iPhone/Cocoa app. It has two table views inside a navigation view. When you touch a row in the first table view, you are taken to the second table view. I would like the second view to display records from the CoreData entities related to the row you touched in the first view. I have the CoreData data showing up fine in the first table view. You can touch a row and go to the second table view. I'm able to pass info from the selected object from the first to the second view. But I cannot get the second view to do its own CoreData fetching. For the life of me I cannot get the managedObjectContext object to pass to the second view controller. I don't want to do the lookups in the first view and pass a dictionary because I want to be able to use a search field to refine results in the second view, as well as insert new entries to the CoreData data from there. Here's the function that transitions from the first to the second view. - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { // Navigation logic may go here -- for example, create and push another view controller. NSManagedObject *selectedObject = [[self fetchedResultsController] objectAtIndexPath:indexPath]; SecondViewController *secondViewController = [[SecondViewController alloc] initWithNibName:@"SecondView" bundle:nil]; secondViewController.tName = [[selectedObject valueForKey:@"name"] description]; secondViewController.managedObjectContext = [self managedObjectContext]; [self.navigationController pushViewController:secondViewController animated:YES]; [secondViewController release]; } And this is the function inside SecondViewController that crashes: - (void)viewDidLoad { [super viewDidLoad]; self.title = tName; NSError *error; if (![[self fetchedResultsController] performFetch:&error]) { // <-- crashes here // Handle the error... } } - (NSFetchedResultsController *)fetchedResultsController { if (fetchedResultsController != nil) { return fetchedResultsController; } /* Set up the fetched results controller. */ // Create the fetch request for the entity. NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; // Edit the entity name as appropriate. // **** crashes on the next line because managedObjectContext == 0x0 NSEntityDescription *entity = [NSEntityDescription entityForName:@"SecondEntity" inManagedObjectContext:managedObjectContext]; [fetchRequest setEntity:entity]; // <snip> ... more code here from Apple template, never gets executed because of the crashing return fetchedResultsController; } Any ideas on what I am doing wrong here? managedObjectContext is a retained property. UPDATE: I inserted a NSLog([[managedObjectContext registeredObjects] description]); in viewDidLoad and it appears managedObjectContext is being passed just fine. Still crashing, though. Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '+entityForName: could not locate an NSManagedObjectModel for entity name 'SecondEntity''

  • Animation not start immediately when the target view is out of window

    - by funnything
    Hi. When I apply some animation to the view, which is out of window, the animation not start immediately. And then, I scroll the screen to show the animation target view, the animation will start. I hope to the animation will start immediately when it apply. Any ideas? Bellow is sample code. Thank you. public class AnimationValidationActivity extends Activity { private ViewSwitcher _viewSwitcher; private Button _button; /** * utility method for animation */ private Animation buildTranslateAnimation( float fromXDelta , float toXDelta , float fromYDelta , float toYDelta ) { Animation ret = new TranslateAnimation( fromXDelta , toXDelta , fromYDelta , toYDelta ); ret.setDuration( 1000 ); return ret; } /** * build view in place of layout.xml */ private View buildView() { ScrollView ret = new ScrollView( this ); ret.setLayoutParams( new LinearLayout.LayoutParams( LinearLayout.LayoutParams.FILL_PARENT , LinearLayout.LayoutParams.WRAP_CONTENT ) ); LinearLayout parent = new LinearLayout( this ); parent.setLayoutParams( new LinearLayout.LayoutParams( LinearLayout.LayoutParams.FILL_PARENT , LinearLayout.LayoutParams.WRAP_CONTENT ) ); parent.setOrientation( LinearLayout.VERTICAL ); ret.addView( parent ); _viewSwitcher = new ViewSwitcher( this ); _viewSwitcher.setLayoutParams( new LinearLayout.LayoutParams( LinearLayout.LayoutParams.FILL_PARENT , 100 ) ); parent.addView( _viewSwitcher ); View spacer = new View( this ); spacer.setLayoutParams( new LinearLayout.LayoutParams( LinearLayout.LayoutParams.FILL_PARENT , getWindow() .getWindowManager().getDefaultDisplay().getHeight() ) ); parent.addView( spacer ); _button = new Button( this ); _button.setText( "button" ); parent.addView( _button ); return ret; } @Override public void onCreate( Bundle savedInstanceState ) { super.onCreate( savedInstanceState ); setContentView( buildView() ); _viewSwitcher.setFactory( new ViewSwitcher.ViewFactory() { @Override public View makeView() { TextView view = new TextView( AnimationValidationActivity.this ); view.setLayoutParams( new ViewSwitcher.LayoutParams( ViewSwitcher.LayoutParams.FILL_PARENT , ViewSwitcher.LayoutParams.FILL_PARENT ) ); view.setBackgroundColor( 0xffffffff ); view.setText( "foobar" ); return view; } } ); _button.setOnClickListener( new View.OnClickListener() { @Override public void onClick( View v ) { _viewSwitcher.setInAnimation( buildTranslateAnimation( _viewSwitcher.getWidth() , 0 , 0 , 0 ) ); _viewSwitcher.setOutAnimation( buildTranslateAnimation( 0 , - _viewSwitcher.getWidth() , 0 , 0 ) ); int color = new Random().nextInt(); _viewSwitcher.getNextView().setBackgroundColor( 0xff000000 | color & 0xffffff ); _viewSwitcher.showNext(); } } ); } }

  • PASS Summit 2012: keynote and Mobile BI announcements #sqlpass

    - by Marco Russo (SQLBI)
    Today at PASS Summit 2012 there have been several announcements during the keynote. Moreover, other news have not been highlighted in the keynote but are equally if not more important for the BI community. Let’s start from the big news in the keynote (other details on SQL Server Blog): Hekaton: this is the codename for in-memory OLTP technology that will appear (I suppose) in the next release of the SQL Server relational engine. The improvement in performance and scalability is impressive and it enables new scenarios. I’m curious to see whether it can be used also to improve ETL performance and how it differs from using SSD technology. Updates on Columnstore: In the next major release of SQL Server the columnstore indexes will be updatable and it will be possible to create a clustered index with Columnstore index. This is really a great news for near real-time reporting needs! Polybase: in 2013 it will debut SQL Server 2012 Parallel Data Warehouse (PDW), which will include the Polybase technology. By using Polybase a single T-SQL query will run queries across relational data and Hadoop data. A single query language for both. Sounds really interesting for using BigData in a more integrated way with existing relational databases. And, of course, to load a data warehouse using BigData, which is the ultimate goal that we all BI Pro have, right? SQL Server 2012 SP1: the Service Pack 1 for SQL Server 2012 is available now and it enable the use of PowerPivot for SharePoint and Power View on a SharePoint 2013 installation with Excel 2013. Power View works with Multidimensional cube: the long-awaited feature of being able to use PowerPivot with Multidimensional cubes has been shown by Amir Netz in an amazing demonstration during the keynote. The interesting thing is that the data model behind was based on a many-to-many relationship (something that is not fully supported by Power View with Tabular models). Another interesting aspect is that it is Analysis Services 2012 that supports DAX queries run on a Multidimensional model, enabling the use of any future tool generating DAX queries on top of a Multidimensional model. There are still no info about availability by now, but this is *not* included in SQL Server 2012 SP1. So what about Mobile BI? Well, even if not announced during the keynote, there is a dedicated session on this topic and there are very important news in this area: iOS, Android and Microsoft mobile platforms: the commitment is to get data exploration and visualization capabilities working within June 2013. This should impact at least Power View and SharePoint/Excel Services. This is the type of UI experience we are all waiting for, in order to satisfy the requests coming from users and customers. The important news here is that native applications will be available for both iOS and Windows 8 so it seems that Android will be supported initially only through the web. Unfortunately we haven’t seen any demo, so it’s not clear what will be the offline navigation experience (and whether there will be one). But at least we know that Microsoft is working on native applications in this area. I’m not too surprised that HTML5 is not the magic bullet for all the platforms. The next PASS Business Analytics conference in 2013 seems a good place to see this in action, even if I hope we don’t have to wait other six months before seeing some demo of native BI applications on mobile platforms! Viewing Reporting Services reports on iPad is supported starting with SQL Server 2012 SP1, which has been released today. This is another good reason to install SP1 on SQL Server 2012. If you are at PASS Summit 2012, come and join me, Alberto Ferrari and Chris Webb at our book signing event tomorrow, Thursday 8 2012, at the bookstore between 12:00pm and 12:30pm, or follow one of our sessions!

  • ASSIMP in my program is much slower to import than ASSIMP view program

    - by Marco
    The problem is really simple: if I try to load with the function aiImportFileExWithProperties a big model in my software (around 200.000 vertices), it takes more than one minute. If I try to load the very same model with ASSIMP view, it takes 2 seconds. For this comparison, both my software and Assimp view are using the dll version of the library at 64 bit, compiled by myself (Assimp64.dll). This is the relevant piece of code in my software // default pp steps unsigned int ppsteps = aiProcess_CalcTangentSpace | // calculate tangents and bitangents if possible aiProcess_JoinIdenticalVertices | // join identical vertices/ optimize indexing aiProcess_ValidateDataStructure | // perform a full validation of the loader's output aiProcess_ImproveCacheLocality | // improve the cache locality of the output vertices aiProcess_RemoveRedundantMaterials | // remove redundant materials aiProcess_FindDegenerates | // remove degenerated polygons from the import aiProcess_FindInvalidData | // detect invalid model data, such as invalid normal vectors aiProcess_GenUVCoords | // convert spherical, cylindrical, box and planar mapping to proper UVs aiProcess_TransformUVCoords | // preprocess UV transformations (scaling, translation ...) aiProcess_FindInstances | // search for instanced meshes and remove them by references to one master aiProcess_LimitBoneWeights | // limit bone weights to 4 per vertex aiProcess_OptimizeMeshes | // join small meshes, if possible; aiProcess_SplitByBoneCount | // split meshes with too many bones. Necessary for our (limited) hardware skinning shader 0; cout << "Loading " << pFile << "... "; aiPropertyStore* props = aiCreatePropertyStore(); aiSetImportPropertyInteger(props,AI_CONFIG_IMPORT_TER_MAKE_UVS,1); aiSetImportPropertyFloat(props,AI_CONFIG_PP_GSN_MAX_SMOOTHING_ANGLE,80.f); aiSetImportPropertyInteger(props,AI_CONFIG_PP_SBP_REMOVE, aiPrimitiveType_LINE | aiPrimitiveType_POINT); aiSetImportPropertyInteger(props,AI_CONFIG_GLOB_MEASURE_TIME,1); //aiSetImportPropertyInteger(props,AI_CONFIG_PP_PTV_KEEP_HIERARCHY,1); // Call ASSIMPs C-API to load the file scene = (aiScene*)aiImportFileExWithProperties(pFile.c_str(), ppsteps | /* default pp steps */ aiProcess_GenSmoothNormals | // generate smooth normal vectors if not existing aiProcess_SplitLargeMeshes | // split large, unrenderable meshes into submeshes aiProcess_Triangulate | // triangulate polygons with more than 3 edges //aiProcess_ConvertToLeftHanded | // convert everything to D3D left handed space aiProcess_SortByPType | // make 'clean' meshes which consist of a single typ of primitives 0, NULL, props); aiReleasePropertyStore(props); if(!scene){ cout << aiGetErrorString() << endl; return 0; } this is the relevant piece of code in assimp view code // default pp steps unsigned int ppsteps = aiProcess_CalcTangentSpace | // calculate tangents and bitangents if possible aiProcess_JoinIdenticalVertices | // join identical vertices/ optimize indexing aiProcess_ValidateDataStructure | // perform a full validation of the loader's output aiProcess_ImproveCacheLocality | // improve the cache locality of the output vertices aiProcess_RemoveRedundantMaterials | // remove redundant materials aiProcess_FindDegenerates | // remove degenerated polygons from the import aiProcess_FindInvalidData | // detect invalid model data, such as invalid normal vectors aiProcess_GenUVCoords | // convert spherical, cylindrical, box and planar mapping to proper UVs aiProcess_TransformUVCoords | // preprocess UV transformations (scaling, translation ...) aiProcess_FindInstances | // search for instanced meshes and remove them by references to one master aiProcess_LimitBoneWeights | // limit bone weights to 4 per vertex aiProcess_OptimizeMeshes | // join small meshes, if possible; aiProcess_SplitByBoneCount | // split meshes with too many bones. Necessary for our (limited) hardware skinning shader 0; aiPropertyStore* props = aiCreatePropertyStore(); aiSetImportPropertyInteger(props,AI_CONFIG_IMPORT_TER_MAKE_UVS,1); aiSetImportPropertyFloat(props,AI_CONFIG_PP_GSN_MAX_SMOOTHING_ANGLE,g_smoothAngle); aiSetImportPropertyInteger(props,AI_CONFIG_PP_SBP_REMOVE,nopointslines ? aiPrimitiveType_LINE | aiPrimitiveType_POINT : 0 ); aiSetImportPropertyInteger(props,AI_CONFIG_GLOB_MEASURE_TIME,1); //aiSetImportPropertyInteger(props,AI_CONFIG_PP_PTV_KEEP_HIERARCHY,1); // Call ASSIMPs C-API to load the file g_pcAsset->pcScene = (aiScene*)aiImportFileExWithProperties(g_szFileName, ppsteps | /* configurable pp steps */ aiProcess_GenSmoothNormals | // generate smooth normal vectors if not existing aiProcess_SplitLargeMeshes | // split large, unrenderable meshes into submeshes aiProcess_Triangulate | // triangulate polygons with more than 3 edges aiProcess_ConvertToLeftHanded | // convert everything to D3D left handed space aiProcess_SortByPType | // make 'clean' meshes which consist of a single typ of primitives 0, NULL, props); aiReleasePropertyStore(props); As you can see the code is nearly identical because I copied from assimp view. What could be the reason for such a difference in performance? The two software are using the same dll Assimp64.dll (compiled in my computer with vc++ 2010 express) and the same function aiImportFileExWithProperties to load the model, so I assume that the actual code employed is the same. How is it possible that the function aiImportFileExWithProperties is 100 times slower when called by my sotware than when called by assimp view? What am I missing? I am not good with dll, dynamic and static libraries so I might be missing something obvious. ------------------------------ UPDATE I found out the reason why the code is going slower. Basically I was running my software with "Start debugging" in VC++ 2010 Express. If I run the code outside VC++ 2010 I get same performance of assimp view. However now I have a new question. Why does the dll perform slower in VC++ debugging? I compiled it in release mode without debugging information. Is there any way to have the dll go fast in debugmode i.e. not debugging the dll? Because I am interested in debugging only my own code, not the dll that I assume is already working fine. I do not want to wait 2 minutes every time I want to load my software to debug. Does this request make sense?

  • Level selection view - similiar to Angry Bird's

    - by Piotr
    I am making game and need to prepare view for level selection. Could you recommend me some opensource library which could I use? I need icons to vibrate after long pressing one of them, some callbacks after choosing them, possibility to prepare custom icon's view, page control and horizontal scrolling. I was trying to use OpenSpringBoard but weirdly couldn't see scrollview and pagecontrol working in this project - it seems that there's possibility to use only one page. On the other hand, myLauncher(https://github.com/dlinsin/myLauncher) isn't so easy to include in project, as I need a seperate view with some delegate methods. I need to be compatible with iOS 4.2
