  • AJAX deeplinking with jQuery Address

    - by antosha
    Hello, I have a website which has many pages: For example: HOME: http://mywebsite.com/index.html SOME PAGE: http://mywebsite.com/categorie/somepage.html I decided to make my pages load dynamically with AJAX without reloading the page. So I decided to use jQuery Address plugin ( http://www.asual.com/jquery/address/docs/ ) in order to allow deeplinking and Back-Forward navigation: <script type="text/javascript" src="uploads/scripts/jquery.address-1.2rc.min.js"></script> <script type="text/javascript"> $('a').address(function() { return $(this).attr('href').replace(/^#/, ''); }); </script> Now, after installing the plugin, if I go on http://mywebsite.com/index.html (HOME) and click on SOME PAGE link, jquery successfully loads the http://mywebsite.com/categorie/somepage.html without reloading the page and the address bar on my browser displays: http://mywebsite.com/index.html/#/categorie/somepage.html which is great! However, the problem is: if I copy this dynamically generated URL: http://mywebsite.com/index.html/#/categorie/somepage.html into a web browser address bar, it will take into my website index.html page and not to the "SOME PAGE" page. Also, The Forward/Back buttons don't work correctly, they only replace the address in the URL bar but the content stays the same. I suppose that I need to write some JavaScript rule that associates the dynamic URL with the correct page? Some help would be appreciated. Thanks :)

  • Programmatically implementing an interface that combines some instances of the same interface in var

    - by namin
    What is the best way to implement an interface that combines some instances of the same interface in various specified ways? I need to do this for multiple interfaces and I want to minimize the boilerplate and still achieve good efficiency, because I need this for a critical production system. Here is a sketch of the problem. Abstractly, I have a generic combiner class which takes the instances and specify the various combinators: class Combiner<I> { I[] instances; <T> T combineSomeWay(InstanceMethod<I,T> method) { // ... method.call(instances[i]) ... combined in some way ... } // more combinators } Now, let's say I want to implement the following interface among many others: Interface Foo { String bar(int baz); } I want to end up with code like this: class FooCombiner implements Foo { Combiner<Foo> combiner; @Override public String bar(final int baz) { return combiner.combineSomeWay(new InstanceMethod<Foo, String> { @Override public call(Foo instance) { return instance.bar(baz); } }); } } Now, this can quickly get long and winded if the interfaces have lots of methods. I know I could use a dynamic proxy from the Java reflection API to implement such interfaces, but method access via reflection is hundred times slower. So what are the alternatives to boilerplate and reflection in this case?

  • Why is this code invalid in C#?

    - by mmattax
    The following code will not compile: string foo = "bar"; Object o = foo == null ? DBNull.Value : foo; I get: Error 1 Type of conditional expression cannot be determined because there is no implicit conversion between 'System.DBNull' and 'string' To fix this, I must do something like this: string foo = "bar"; Object o = foo == null ? DBNull.Value : (Object)foo; This cast seems pointless as this is certainly legal: string foo = "bar"; Object o = foo == null ? "gork" : foo; It seems to me that when the ternary branches are of different types, the compiler will not autobox the values to the type object...but when they are of the same type then the autoboxing is automatic. In my mind the first statement should be legal... Can anyone describe why the compiler does not allow this and why the designers of C# chose to do this? I believe this is legal in Java...Though I have not verified this. Thanks. EDIT: I am asking for an understanding of why Java and C# handle this differently, what is going on underneath the scenes in C# that make this invalid. I know how to use ternary, and am not looking for a "better way" to code the examples. I understand the rules of ternary in C#, but I want to know WHY... EDIT (Jon Skeet): Removed "autoboxing" tag as no boxing is involved in this question.

  • UISearchDisplayController not working when created in code??

    - by Nick Bedford
    I'm working on a tab bar application and one of the tabs has a UISearchDisplayController hooked up to a UISearchBar. It's all connected up in the NIB and is working. When I tap the search bar, the Scope and Cancel buttons fly in etc, and the search delegate updates the results table correctly. However, I'm trying to implement the same code in the viewDidLoad message instead of the NIB, however when I delete the search display controller from the NIB and uncomment my code to create the same controller in the function, it doesn't work. It's as if there's some fundamental connection not being made so that all my search delegate functionality isn't being called. Here's my working NIB version of the Search Display Controller. It's hooked up to the search bar, the UINavigationController subclass (MASearchController) and the root view of that is hooked up as the searchContentsController. Now this is what you would expect to do in code to create the same, right? What I'm doing is leaving the UISearchBar in the NIB to eliminate one piece of the puzzle at a time in code. // [MASearchController viewDidLoad] UISearchDisplayController *searchController = [[[UISearchDisplayController alloc] initWithSearchBar:searchBar contentsController:[[self viewControllers] objectAtIndex:0]] autorelease]; [searchController setDelegate:self]; [searchController setSearchResultsDelegate:self]; [searchController setSearchResultsDataSource:self]; I've checked all objects at run time and they all check out. Essentially I've deleted the search display controller from the NIB and then put in the code to create it in the viewDidLoad message. Why would this not work? The search keyboard comes up but none of my search and button animation functionality work???

  • UINavigationBar is getting buttons from another view

    - by Rafael Oliveira
    I have three Views, Splash, Login and List. From Splash I just wait and then Push Login View, with the Navigation Bar hidden. In Login I Show the NavigationBar, hide the BackButton1 and add a new RightButton1, then I check if Settings.bundle "login" and "pass" are set. If so, I push List View. Otherwise I stay in the Login view waiting for the user to fill the form and press a button. In List View I add a new RightButton2 and a new BackButton2. The problem is that if Settings.bundle data is not null, and in Login View I quickly push List View the RightButton1 appears in List View, or no buttons appear at all, or only BackButton2 doesn't appear... The most strange thing of all is that everything was OK and all of sudden it started to get messy. Login View: // Making the Navigation Bar Visible [self.navigationController setNavigationBarHidden:NO animated:NO]; // Hiding the Back Button in THIS view (Login) [self.navigationItem setHidesBackButton:YES]; // Inserting the Logout Button for the Next View (List) UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:@"Logout" style:UIBarButtonItemStylePlain target:nil action:nil]; self.navigationItem.backBarButtonItem = backButton; [backButton release]; UIBarButtonItem* newAccountButton = [[UIBarButtonItem alloc] initWithTitle:@"New Account" style:UIBarButtonItemStylePlain target:self action:@selector(newAccountButtonPressed)]; self.navigationItem.rightBarButtonItem = newAccountButton; [newAccountButton release]; List View // Making the Navigation Bar Visible [self.navigationController setNavigationBarHidden:NO animated:NO]; UIBarButtonItem* aboutButton = [[UIBarButtonItem alloc] initWithTitle:@"About" style:UIBarButtonItemStylePlain target:self action:@selector(aboutButtonPressed)]; self.navigationItem.rightBarButtonItem = aboutButton; [aboutButton release]; Any ideas ?

  • jQuery does not return a JSON object to Firebug when JSON is generated by PHP

    - by Keyslinger
    The contents of test.json are: {"foo": "The quick brown fox jumps over the lazy dog.","bar": "ABCDEFG","baz": [52, 97]} When I use the following jQuery.ajax() call to process the static JSON inside test.json, $.ajax({ url: 'test.json', dataType: 'json', data: '', success: function(data) { $('.result').html('<p>' + data.foo + '</p>' + '<p>' + data.baz[1] + '</p>'); } }); I get a JSON object that I can browse in Firebug. However, when using the same ajax call with the URL pointing instead to this php script: <?php $arrCoords = array('foo'=>'The quick brown fox jumps over the lazy dog.','bar'=>'ABCDEFG','baz'=>array(52,97)); echo json_encode($arrCoords); ?> which prints this identical JSON object: {"foo":"The quick brown fox jumps over the lazy dog.","bar":"ABCDEFG","baz":[52,97]} I get the proper output in the browser but Firebug only reveals only HTML. There is no JSON tab present when I expand GET request in Firebug.

  • Remove clear button (grey x) to the right of UISearchBar when cancel button tapped

    - by David Foster
    Right, to begin my question, here's some screenies of the problem already solved by the Spotify app: Spotify's Step 1: Standard UISearchBar not in editing mode. Spotify's Step 2: UISearchBar now in editing mode. Search term entered. Cancel button slides in from the right, and the clear button (grey x) appears. Spotify's Step 3: Cancel button pressed; keyboard slides out and the search bar is no longer in editing mode. Search term remains and the grey x button is now hidden. At present, the following code fires off when my cancel button is pressed: - (void)searchBarCancelButtonClicked:(UISearchBar *)searchBar { [searchBar resignFirstResponder]; [searchBar setShowsCancelButton:NO animated:YES]; } Which results in: My Step 3: Search bar now not in editing mode. Cancel button and keyboard has slid out. Search term remains but so does the grey x. So, my question is this: given that -resignFirstResponder (and -endEditing:, FYI) does not hide the grey x button when a search bar has had text entered into it, how does one hide it? Thanks again, friends.

  • How does VS 2005 provide history across all TFS Team Projects when tf.exe cannot?

    - by AakashM
    In Visual Studio 2005, in the TFS Source Control Explorer, these is a top-level node for the TFS Server itself, with a child node for each Team Project. Right-clicking either the server node or the node for a Team Project gives a context menu on which there is a View History item. Selecting this gives you a History window showing the last 200 or so changesets, either for the specific Team Project chosen, or across all Team Projects. It is this history across all Team Projects that I am wondering about. The command-line tf.exe history command provides (as I understand it) basically the same functionality as is provided by the VS TFS Source Control plug-in. But I cannot work out how to get tf.exe history to provide this across-all-Team-Projects history. At a command line, supposing I have C:\ mapped as the root of my workspace, and Foo, Bar, and Baz as Team Projects, I can do C:\> tf history Foo /recursive /stopafter:200 to get the last 200 changesets that affected Team Project Foo; or from within a Team Project folder C:\Bar> tf history *.* /recursive /stopafter:200 which does the same thing for Team Project Bar - note that the wildcard *.* is allowed here. However, none of these work (each gives the error message shown): C:\> tf history /recursive /stopafter:200 The history command takes exactly one item C:\> tf history *.* /recursive /stopafter:200 Unable to determine the source control server C:\> tf history *.* /server:servername /recursive /stopafter:200 Unable to determine the workspace I don't see an option in the docs for tf for specifying a workspace; it seems to only want to determine it from the current folder. So what is VS 2005 doing? Is it internally doing a history on each Team Project in turn and then sticking the results together?? note also that I have tried with Power Tools; tfpt history from the command line gives exactly the same error messages seen here

  • Blueprint CSS & Boks: strange behavior with prepend and append in FF and Chrome

    - by Shyam
    Hi, I am working a bit with Blueprint CSS framework and I stumbled upon Boks. I am pretty unfamiliar with the BPCSS framework, but it seems that when using prepend and append, Firefox and Chrome (both) are not liking the input. I generated the code from Boks and for my newbe eye-sight, I can't directly see what went wrong in the export. Even though the span-sizes are correct, they are mutated :S Please help me! <div class="container showgrid"> <!-- first row --> <div class="span-3 prepend-2" id="bar-menuitems"> </div> <div class="span-6 prepend-4" id="banner-logo"> </div> <div class="span-3 prepend-4 append-2 last" id="bar-socialmedia"> </div> <!-- second row --> <div class="clear span-20 prepend-2 append-2 last" id="pane-graphics"> </div> <!-- third row --> <div class="clear span-5 prepend-2" id="banner-xx1"> </div> <div class="span-5" id="banner-xx2"> </div> <div class="span-5" id="banner-xx3"> </div> <div class="span-5 append-2 last" id="banner-xx4"> </div> <!-- last row --> <div class="clear span-6 prepend-9 append-9 last" id="bar-footer"> </div> </div>

  • MVC: capture route url's and pass them to javascript function

    - by Tim Geerts
    Short:Is there a way to have a route-definition that will pass the "CONTROLLER/ACTION" string value to a javascript function in stead of actually going straight for the controller action? More:I have a masterpage which contains the navigation of the site. Now, all the pages need this navigation wrapped around it at all times, but because I didn't want the navigation to constantly load with each pagecall, I changed all my pages to partialviews. These partial views are loaded via the JQuery.Load() method whenever a menu item is clicked in the navigation. This all worked very good, up till now because I noticed it's also a requirement of the website to be able to link directly to page X, rather then default.aspx. So, as an example:The main page is my "default.aspx" page, this utilizes my master page with the nagivation around it. And each call to a new page uses a javascript function that loads that particular partial view inside a div that is known in my masterpage. So, the url never changes away from "default.aspx", but my content changes seemlesly. The problem is, those url's also need to be available when typed directly into the address bar. But, they're partial views, so loading them directly from the address bar makes them display without any masterpages around them. Therefore my question if it might be possible to capture the route typed into the address bar and pass that on to my javascript function that will load that route in the content div. (I hope I explained it ok enough, if not, feel free to ask more information)

  • Skip makefile dependency generation for certain targets (e.g. `clean`)

    - by Shtééf
    I have several C and C++ projects that all follow a basic structure I've been using for a while now. My source files go in src/*.c, intermediate files in obj/*.[do], and the actual executable in the top level directory. My makefiles follow roughly this template: # The final executable TARGET := something # Source files (without src/) INPUTS := foo.c bar.c baz.c # OBJECTS will contain: obj/foo.o obj/bar.o obj/baz.o OBJECTS := $(INPUTS:%.cpp=obj/%.o) # DEPFILES will contain: obj/foo.d obj/bar.d obj/baz.d DEPFILES := $(OBJECTS:%.o=%.d) all: $(TARGET) obj/%.o: src/%.cpp $(CC) $(CFLAGS) -c -o $@ $< obj/%.d: src/%.cpp $(CC) $(CFLAGS) -M -MF $@ -MT $(@:%.d=%.o) $< $(TARGET): $(OBJECTS) $(LD) $(LDFLAGS) -o $@ $(OBJECTS) .PHONY: clean clean: -rm -f $(OBJECTS) $(DEPFILES) $(RPOFILES) $(TARGET) -include $(DEPFILES) Now I'm at the point where I'm packaging this for a Debian system. I'm using debuild to build the Debian source package, and pbuilder to build the binary package. The debuild step only has to execute the clean target, but even this causes the dependency files to be generated and included. In short, my question is really: Can I somehow prevent make from generating dependencies when all I want is to run the clean target?

  • Java Swing Threading with Updatable JProgressBar

    - by Anthony Sparks
    First off I've been working with Java's Concurency package quite a bit lately but I have found an issue that I am stuck on. I want to have and Application and the Application can have a SplashScreen with a status bar and the loading of other data. So I decided to use SwingUtilities.invokeAndWait( call the splash component here ). The SplashScreen then appears with a JProgressBar and runs a group of threads. But I can't seem to get a good handle on things. I've looked over SwingWorker and tried using it for this purpose but the thread just returns. Here is a bit of sudo-code. and the points I'm trying to achieve. Have an Application that has a SplashScreen that pauses while loading info Be able to run multiple threads under the SplashScreen Have the progress bar of the SplashScreen Update-able yet not exit until all threads are done. Launching splash screen try { SwingUtilities.invokeAndWait( SplashScreen ); } catch (InterruptedException e) { } catch (InvocationTargetException e) { } Splash screen construction SplashScreen extends JFrame implements Runnable{ public void run() { //run threads //while updating status bar } } I have tried many things including SwingWorkers, Threads using CountDownLatch's, and others. The CountDownLatch's actually worked in the manner I wanted to do the processing but I was unable to update the GUI. When using the SwingWorkers either the invokeAndWait was basically nullified (which is their purpose) or it wouldn't update the GUI still even when using a PropertyChangedListener. If someone else has a couple ideas it would be great to hear them. Thanks in advance.

  • Interpolating environment variables into a string in Ruby using String#scan

    - by robc
    I'm trying to interpolate environment variables into a string in Ruby and not having much luck. One of my requirements is to do something (log an error, prompt for input, whatever) if a placeholder is found in the initial string that has no matching environment variable. It looks like the block form of String#scan is what I need. Below is an irb session of my failed attempt. irb(main):014:0> raw_string = "need to replace %%FOO%% and %%BAR%% in here" => "need to replace %%FOO%% and %%BAR%% in here" irb(main):015:0> cooked_string << raw_string => "need to replace %%FOO%% and %%BAR%% in here" irb(main):016:0> raw_string.scan(/%%(.*?)%%/) do |var| irb(main):017:1* cooked_string.sub!("%%#{var}%%", ENV[var]) irb(main):018:1> done irb(main):019:1> end TypeError: cannot convert Array into String from (irb):17:in `[]' from (irb):17 from (irb):16:in `scan' from (irb):16 from :0 If I use ENV["FOO"] to manually interpolate one of those, it works fine. I'm banging my head against the desk. What am I doing wrong? Ruby is 1.8.1 on RHEL or 1.8.7 on Cygwin.

  • Cross-domain templating with Javascript

    - by Husky
    I'm currently building a Javascript library that can be used to easily create embeddable media based on the URL of a media file, and then be controlled using Javascript methods and events (think something like the Flash / Silverlight JW player). Of course, i could simply cat all the html tags from the Javascript library and send that to the browser: function player(url) { document.write('<object type="foo"><param name="something" value="bar">' + <param name="source" value=" + url + '/></object>'); } But i think this is a very ugly practice that tends to create unmanageable code that is unreadable when you review it a few weeks later. So, a templating solution seems to be the way to go. I've been looking to EJS because it loads the templates using AJAX, so you can manage your templates in separate file instead of directly on the HTML page. There's one 'gotcha' with that: my library needs to be completely cross-domain: the library itself could be located on foo.com while the serving site could be located on bar.com. So if bar.com would want to add a media player using the library it needs to do an AJAX call to a template located on foo.com, which won't work because of the same-origin policy in browsers. AFAIK, there's no library that uses something like JSONP to read and write templates to get around this problem. Could anyone point me to a solution for this problem?

  • Adding a UIPickerView over a UITabBarController

    - by Kai
    I'm trying to have a UIPickerView slide from the bottom of the screen (over the top of a tab bar) but can't seem to get it to show up. The actual code for the animation is coming from one of Apple's example code projects (DateCell). I'm calling this code from the first view controller (FirstViewController.m) under the tab bar controller. - (IBAction)showModePicker:(id)sender { if (self.modePicker.superview == nil) { [self.view.window addSubview:self.modePicker]; // size up the picker view to our screen and compute the start/end frame origin for our slide up animation // // compute the start frame CGRect screenRect = [[UIScreen mainScreen] applicationFrame]; CGSize pickerSize = [self.modePicker sizeThatFits:CGSizeZero]; CGRect startRect = CGRectMake(0.0, screenRect.origin.y + screenRect.size.height, pickerSize.width, pickerSize.height); self.modePicker.frame = startRect; // compute the end frame CGRect pickerRect = CGRectMake(0.0, screenRect.origin.y + screenRect.size.height - pickerSize.height, pickerSize.width, pickerSize.height); // start the slide up animation [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:0.3]; // we need to perform some post operations after the animation is complete [UIView setAnimationDelegate:self]; self.modePicker.frame = pickerRect; // shrink the vertical size to make room for the picker CGRect newFrame = self.view.frame; newFrame.size.height -= self.modePicker.frame.size.height; self.view.frame = newFrame; [UIView commitAnimations]; // add the "Done" button to the nav bar self.navigationItem.rightBarButtonItem = self.doneButton; }} Whenever this action fires via a UIBarButtonItem that lives in a UINavigationBar (which is all under the FirstViewController) nothing happens. Can anyone please offer some advice?

  • does anyone know of good delphi docking components?

    - by X-Ray
    we'd like to add movable panels to an application. presently we've used DevExpress docking library but have found them to be disappointingly quirky & difficult to work with. it also has some limitations that aren't so great. auto-hide, pinning, and moving of pages by drag-and-drop are all features we'd like to use. the built-in delphi docking doesn't seem to be full-featured enough to do the things we need (also see sample below). perhaps i should dig deeper into delphi's docking abilities...my initial impression is that they seem very toolbar-oriented rather than something i can drop a frame into. i'm not experienced at docking topics. my only experience has been with the DevExpress docking library where i needed to programmatically create & dock panels. is it my imagination or are DevExpress's products unduly difficult to use/learn? the DevExpress Ribbon Bar component compared to the d2009 Ribbon Bar was certainly a useful experience. i will migrate to the d2009 Ribbon Bar as soon as convenient to do so. it was refreshingly straight-forward to learn and use. a sharp contrast compared to the DevExpress equivalent. if it takes 4x as longer to make it using the DevExpress equivalent, it's time to change direction. what would you suggest in regard to the docking library? thank you for your suggestions/comments!

  • Python print statement prints nothing with a carriage return

    - by Jonathan Sternberg
    I'm trying to write a simple tool that reads files from disc, does some image processing, and returns the result of the algorithm. Since the program can sometimes take awhile, I like to have a progress bar so I know where it is in the program. And since I don't like to clutter up my command line and I'm on a Unix platform, I wanted to use the '\r' character to print the progress bar on only one line. But when I have this code here, it prints nothing. # Files is a list with the filenames for i, f in enumerate(files): print '\r%d / %d' % (i, len(files)), # Code that takes a long time I have also tried: print '\r', i, '/', len(files), Now just to make sure this worked in python, I tried this: heartbeat = 1 while True: print '\rHello, world', heartbeat, heartbeat += 1 This code works perfectly. What's going on? My understanding of carriage returns on Linux was that it would just move the line feed character to the beginning and then I could overwrite old text that was written previously, as long as I don't print a newline anywhere. This doesn't seem to be happening though. Also, is there a better way to display a progress bar in a command line than what I'm current trying to do?

  • Adjust size of MPMediaPickerController's view ?

    - by Mr.Gando
    In my application I don't use the upper bar that displays Wi-Fi/Date/Time because it's a game. However I need to be able to let my user to pick his music, so I'm using a MPMediaPickerController. The problem is, that when I present my controller, the controller ends up leaving a 10 pixels ( aprox ) bar at the top of the screen, just in the place the Wi-Fi/Date/Time bar, should be present. Is there a way I could make my MPMediaPickerController bigger ? or to be presented upper in the screen ? // Configures and displays the media item picker. - (void) showMediaPicker: (id) sender { MPMediaPickerController *picker = [[MPMediaPickerController alloc] initWithMediaTypes: MPMediaTypeAnyAudio]; [[picker view] setFrame:CGRectMake(0, 0, 320, 480)]; picker.delegate = self; picker.allowsPickingMultipleItems = YES; picker.prompt = NSLocalizedString (@"AddSongsPrompt", @"Prompt to user to choose some songs to play"); [self presentModalViewController:picker animated: YES]; [picker release]; } There I tried to set the size to 320x480 but no luck, the picker is still presented and leaves a space in the upper part of the screen, could anyone help me ? Btw, here's how it looks: I have asked a bit, and people told me this could indeed be a bug, what do you guys think ?

  • How much should the AppDelegate do?

    - by Rudiger
    I'm designing quite a large App and on startup it will create sessions with a few different servers. As they are creating a session which is used across all parts of the app its something I thought would be best in App Delegate. But the problem is I need the session progress to be represented on the screen. I plan to have a UIToolBar at the bottom of the main menu which I don't want to cover with the progress bar but cover the UIView above it.So the way I see it I could do it a few different ways. 1) Have the App Delegate establish the sessions and report the progress to the main menu class so it can represent it in the progress bar (will I have any issues doing this if the sessions are created in a separate thread?), 2) have the App delegate display the main menu (UIView with a bunch of buttons and UIToolBar) and have it track and display the progress (I have never displayed anything in the App Delegate but assume you can do this but its not recommended) or 3) have the App Delegate just push the main menu and have the mainMenu class create the sessions and display the progress bar. 4) I think the other way to do it is to create the sessions in a delegate class and have the delegate set to mainMenu rather than self (AppDelegate), although I've never used anything other then self so not sure if this will work or if I will be able to close the thread (through calling super maybe?) as its running in the AppDelegate rather than the delegate of the class. As I've kinda said before the sessions are being created in a class in a separate thread so it wont lock the UI and I think the best way is the first but am I going to have issues having it running in a separate thread, reporting back to the app delegate and then sending that message to the mainMenu view? I hope that all makes sense, let me know if you need any further clarification. Any information is appreciated Cheers,

  • How do I reliably get the size of my iPhone view taking rotations into consideration?

    - by Sebastian Celis
    My application uses a UITabBarController, multiple UINavigationControllers, and supports autorotation. In order to properly layout the subviews within each UIViewController's main view, I really need to know the size available to the UIViewContoller. I need this size to take the UINavigationBar, the UITabBar, and the status bar all into account, and thus only return the size available to the content view. I thought for sure I could use the following from within the UIViewController's code: CGRect viewControllerBounds = [[self view] bounds]; However, there are a couple of issues with this approach: The first time the view is loaded, viewControllerBounds reports the view as being 320 pixels wide by 460 pixels tall. This is wrong. With a status bar and a navigation bar showing, the height should only be 416 pixels. However, if I rotate the simulator to landscape and then rotate back, the height of viewControllerBounds changes to 416. If I rotate the first view in the navigation controller to landscape mode and then push another view controller onto the stack, viewControllerBounds for the new view reports a width of 300 pixels and a height of 480 pixels. So the view's bounds didn't even take the rotation into account. Is there a better way to do this? I really don't want to have to start hardcoding the widths and heights of all the various UI elements the iPhone OS provides. I have tried setting the autoresizing mask of the UIViewController's view, but that doesn't seem to change anything. The views definitely seem to be displaying properly. When I set a background color that view looks like it takes up all of the space available to it. Any pointers would be greatly appreciated.

  • Strange GWT serialization exception when overiding method of serialized object

    - by Flueras Bogdan
    Hi there! I have a GWT serializable class, lets call it Foo. Foo implements IsSerializable, has primitive and serializable members as well as other transient members and a no-arg constructor. class Foo implements IsSerializable { // transient members // primitive members public Foo() {} public void bar() {} } Also a Service which handles RPC comunication. // server code public interface MyServiceImpl { public void doStuff(Foo foo); } public interface MyServiceAsync { void doStuff(Foo foo, AsyncCallback<Void> async); } How i use this: private MyServiceAsync myService = GWT.create(MyService.class); Foo foo = new Foo(); ... AsyncCallback callback = new new AsyncCallback {...}; myService.doStuff(foo, callback); In the above case the code is running, and the onSuccess() method of callback instance gets executed. But when I override the bar() method on foo instance like this: Foo foo = new Foo() { public void bar() { //do smthng different } } AsyncCallback callback = new new AsyncCallback {...}; myService.doStuff(foo, callback); I get the GWT SerializationException. Please enlighten me, because I really don't understand why.

  • Adding shortcut for WiX file in a different fragment.

    - by matt
    I'm using heat.exe to generate fragments similar to this: <Fragment> <DirectoryRef Id="INSTALLDIR"> <Component Id="id1" Guid="*"> <File Id="fid1" KeyPath="yes" Source="SourceDir\Foo1.dll" /> </Component> <Component Id="id2" Guid="*"> <File Id="fid2" KeyPath="yes" Source="SourceDir\Foo2.dll" /> </Component> <Component Id="id3" Guid="*"> <File Id="fid3" KeyPath="yes" Source="SourceDir\Bar.exe" /> </Component> </DirectoryRef> </Fragment> <Fragment> <ComponentGroup Id="Components"> <ComponentRef Id="id1" /> <ComponentRef Id="id2" /> <ComponentRef Id="id3" /> </ComponentGroup> </Fragment> These fragments are stored in the auto-generated wxs file. I'm then adding them into my feature (in the main WiX file) like so: <ComponentGroupRef Id="Components"/> This works fine. However, I'd also like to add a shortcut to Bar.exe to my start menu. I ideally want to do this in my main wix file, with the Bar.exe component still residing in the auto-generated wxs file. How would I approach this problem without modifying the auto-generated code?
