• Embeded video displayed over html

  - by Sergey Osypchuk

  Site which I am developing has a menu with drop downs, which is always on top and content is scrollable. Some of content are embeded video from various sources, which appears over top navigation. For youtube, we find solution by adding extra parameter: <param name="wmode" value="opaque" /> which resolve this issue, but what can i do to fix other video sources? You may see issue on this page - http://cars.topics.ua/ru/Topic/ViewGoodie/176768, please scroll down to see video positioned in front of html.

• Received memory warning and app crashes - iphone

  - by Anand Gautam

  I am creating an app using ARC but my app is crashing due to Received memory warning. The App is working fine in simulator. But in case of iphone device, If i run the app for few minutes then on doing anything, the app crashes straightaway. I have checked my app by xcode instrument. My app folder size is 6 MB but all memory allocation is showing 63 MB on xcode instrument. Because of this reason, presentViewController-Animated-Completion is getting slow during navigation. Does anyone have any solution why this is happening?

• Strange centering problem in Firefox and IE8

  - by Davy8

  The navigation bar on my site http://hungryathome.net doesn't center properly on Firefox and IE8 Standards mode. It centers properly in IE7 Compatability mode and in Chrome. What's odd is that setting a Margin on the div (id="navlinks") to 4px or more will make it center properly. Any less will result in it being slightly off-center. I changed the values back and forth in Firebug and it's confusing the heck out of me. Any explanation for why that's happening?

• UIWebView in multithread ViewController

  - by Tao

  I have a UIWebView in a viewcontroller, which has two methods as below. The question is if I pop out(tap back on navigation bar) this controller before the second thread is done, the app will crash after [super dealloc], because "Tried to obtain the web lock from a thread other than the main thread or the web thread. This may be a result of calling to UIKit from a secondary thread.". Any help would be really appreciated. -(void)viewDidAppear:(BOOL)animated { [super viewWillAppear:animated]; NSInvocationOperation *operation = [[NSInvocationOperation alloc] initWithTarget:self selector:@selector(load) object:nil]; [operationQueue addOperation:operation]; [operation release]; } -(void)load { [NSThread sleepForTimeInterval:5]; [self performSelectorOnMainThread:@selector(done) withObject:nil waitUntilDone:NO]; }

• Looking for C# framework for plotting scientific data: 2d/3d ...

  - by Ivan

  I need to visualize some scientific calculations. I generally prefer reusing code if there is already a good available instead of inventing wheels each time, that's why I am asking. I need a C# code to draw charts (just outputting a bitmap is ok) of 2d (y=f(x)) and 3d (z=f(x,y)) digital data sets (where any axis can be float, int or datetime), sometimes combined. If I go here and click 3D in the navigation bar on the left, there I can see what I need. But the cheapest version costs $759 there, looks scary for a hobby project of an east-european student :-(

• How can one use the "Add view" dialog in Visual Studio efficiently when working with ASP.NET MVC?

  - by Marek

  Does anyone else think that the add view dialog in VS is useless or is it just me? Why is there no search/filtering in there? I can not even paste the type name (without namespace) there to speed up the view creation. Plus, there are a lot of irrelevant classes there, including classes from all referenced libraries. Am I missing something or Microsoft never did any usability testing with that?? Is it possible to filter out types/assemblies in the dialog and/or better navigation compared to manually scrolling the combobox with all the types listed? Is it possible to include only types from a particular directory/assembly/namespace? (the ViewModels namespace for example) EDIT: As it seems from the answers that there is no usable workaround for this, I have filed a suggestion at Connect: https://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?FeedbackID=507784 Please vote for the suggestion if you find this is an important issue.

• View Window Not Opening in Interface Builder

  - by senfo

  When I double click the XIB file in Xcode, Interface Builder typically launches a few different windows, one of which is the View window. For some reason, however, the View window isn't opening for one of my XIB files. If I open any of the other XIB files, however, the View window does open. I'm not sure if there's a way to manually launch the View window (I looked through all of the menu items and couldn't find a way) or if I broke something in my XIB. Update: I created a connection from the app delegate to a navigation controller, which seemed to break something. When I cleared that connection, the View window came back.

• facebook iphone app architecture

  - by xoail

  does anyone know or predict how facebook's iphone app architecture could look like? More specific to what could be built into the app (client) what could be rendered on demand? Do you think the main menu layout of the app (where all the navigation buttons are there) are on the client or being rendered dynamically? Similarly apps like NYTimes or US News, what portion is done on the client and what is rendered dynamically. What could be the best way to render things on-demand. Would it be ok to use to UIWebView and render most of the app in it? A quick overview would help. Thank you!

• UITableView with Core Data and fetchedResultsController - don't want to call it at start up

  - by zebulon

  Hi all, I started with the Navigation-based application. I have a UITableView that shows the content fetched from CoreData - using the - (NSFetchedResultsController *)fetchedResultsController from the template. The thing is that I don't want to fill the TableView with the results at the start-up, instead I want to fill the TableView with the results from a search. In my app I have an UITextField, where the user can type a string. And from that string, using predicate, I want to fill the UITableView with the results. In other words, at start-up, the UITableView should be empty and later filled with the search-results. Does anyone have an idea on how to accomplish this? Thanks in advance! EDIT: Solved it by moving out if (![fetchedResultsController_ performFetch:&error]) { and calling it later. I feel a bit stupid ;)

• Slowness of Netbeans Platform Apps - how to mitigate?

  - by user559298

  Hi, We are developing a commerical application (pretty complex) in java using Netbeans IDE. We have 2 options in netbeans to create it- 1. Develop Java desktop app 2. Netbeans Platform app We have requirement that application startup and response times should be very very fast, should be modular etc. We did Proof of Technology by creating apps using both approaches mentioned above. We found Netbeans platform apps are very slow during startup and during screen navigation compared to pure Swing based desktop apps. We tried to implement suggestions provided at http://wiki.netbeans.org/Category:Performance:FAQ and in other blogs and forums to improve on speed of the app but were not successful. We feel for creating a complex desktop app Netbeans platform app would be better suited, but its not meeting our performance requirements (startup and response times, memory footprints, CPU usage guidelines etc). Can any one guide us on how to mitigate our problem of improving performance of Netbeans Platforms apps? Thanks in advance for your help. -bhan

  What is the best practice for opening a map from the mobile internet explorer on windows phone 7? On BlackBerry you use a JavaScript method and on Android/iOS you simply link to a google maps URL.

• iphone sdk: Table view not working in the first 5 tabs but in the more view

  - by LHT

  Hi, I only started with sdk but this problem is bugging me now for a view days: I created a UITableView and added it to my Tabs. When this TableView is in the first 4 Tabs and u go look at it, it only shows the items on the table but when clicking on them nothing happens (it doesn't go to the next view). BUT when i put this same tab behind the 5th so it goes in the automatic MORE view everything works fine. I'm assuming this is because this more view is implementing some kind of table class. But i can't figure it out. I compared all the files with a working example but it seems to be all the same. ah ya my current project is a window based application. Though i copied most of the code from a navigation based application. Any ideas?

• Did anyone see the spasticNav.js Menu for jQuery ?

  - by Ricky

  Helooo all, If anyone doesn't know what i'm talking about, this is the link: http://net.tutsplus.com/tutorials/html-css-techniques/how-to-build-a-lava-lamp-style-navigation-menu/ How can i click the menu, and make it “stick” :) without reloading the whole page ? The plugin takes a static state of the tag UL – and run the plugin on it. which mean that if i move the “currentPageItem” from the first LI tag and give it to the next LI tag – the spasticNav doesn’t run for each object again. it still “remembers” the old state. ( because the .js file run only once at the top of the page ) So what should I add to the code in order to get dynamic “Click” event ? ( without reloading the whole page [ ajax ] ) Does anyone have any ideas about this specific plugin ? Thanks.

• JQuery Tooltip and Scrollable Fix

  - by KrippledShark

  I have set up the navigation on my site using a scrollable div created with Flowplayer's JQuery tools. I also want to add a tooltip to the individual images within the scrollable div. The problem is the tooltip needs to appear outside of the div. I can adjust the height of the div so you can see the tooltip, but the tooltip is still constrained inside another div. Here is the link to my code. http://staging.asla.org/sustainablesites/TestAGAIN.html Is there a way to make this tooltip (div) appear out of it's containing divs?

• ASP.NET: Unable to validate data.

  What is the cause of this exception in ASP.NET?

• TabBar implementation issue in iphone

  - by iPhoneDev

  Hi, My project is navigation based template and it was running fine until I made changes in some child view. I need to add 4 Tab in some child view. So what I did is create a TabBarController programmatically on ViewDidLoad as: // (void)viewDidLoad { [super viewDidLoad]; helpView = [[HelpView alloc] initWithNibName:@"HelpView" bundle:nil]; settingView = [[SettingView alloc] initWithNibName:@"SettingView" bundle:nil]; tabBarController = [[UITabBarController alloc] init]; tabBarController.viewControllers = [NSArray arrayWithObjects:helpView,settingView,nil]; [self.view addSubview:[tabBarController view]]; } I am able to add two view in tab bar but not Tab Title. Please let me know what I am missing to display Title on tab button. ( Is a NavigationBased project) Thanks

• Polishing an user interface

  - by elec

  Looking for examples of some "final touches" to enhance an existing (raw) user interface. I.e nothing related to the core functionalities of the application, but rather examples of all these little details which give an application a "polished" look (new fonts, change in layout, more descriptive labels...others ?) The target platform will be a mobile platform (android/iphone). Note that I'm severly graphically impaired regarding colour and shape combinations, so anything too sophisticated will probably pass me by completely ;)

• Is it a good idea to work on header files only, just at the start of the project?

  - by m4design

  To explain my point further, I'm a beginner in programming, and I'm working on a small project. Instead of separating the .cpp file from the header file, I'm implementing the code in the header files, and making one .cpp file for testing. I do this to have less files, hence easier navigation. Then later I'll separate the code as it should be. Will this cause any problems? should I continue doing that? Thanks.

• Animated status bar style transition, a la iPod app

  - by Ben Williamson

  In the iPod app, the navigation views have the default status bar style, and the Now Playing view is in the black style. The transition between them is animated with a crossfade. I want to do that. My first attempt: [UIView beginAnimations:@"whatever" context:nil]; [UIView setAnimationDuration:0.5]; self.navigationController.navigationBar.barStyle = UIBarStyleBlack; [UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleBlack [UIView commitAnimations]; No joy, it pops to black. Takers?

• iPad: How Do I Limit the Number of Tabs in UITabBarController?

  - by Chris_K

  I'm converting an iPhone app to a universal app, which leaves me with a UITabBarController as the root view controller for a UISplitViewController. That is, the tab bar appears at the bottom of the left-hand view when the iPad is in landscape mode. On the iPhone, the system automatically limited the number of tabs shown in the tab bar to 5. But on the iPad simulator (which is all I have at the moment), my tab bar has 8 tabs, including the More tab. What gives? Thanks. Update: Since I had no luck finding an answer to this question, I gave up on using a tab bar interface in my iPad-flavored app. Instead, I added one more level to the navigation controller drill-down. That ends up working fine for this app.
