• CSS - 2 divs side-by-side, one floated - how do I make the other fit next to it without overlapping?

  - by Artem Russakovskii

  I have had the following problem for a while and I am really not sure how to solve it. The problem can currently be observed here: http://www.androidpolice.com/2009/11/16/the-not-so-good-the-bad-and-the-ugly-my-list-of-20-problems-with-htc-hero/ - feel free to use this for Firebugging. There are 2 notions here: a table of contents (toc) and notes. A note usually takes 100% of the post width and everything is fine. However, when a note appears next to a toc, the toc starts overlapping and covering the note (I set z-index:1 on the toc because otherwise the note covered it, which was even worse). It's interesting to point out that the text of the note doesn't get covered by the toc - only the note div itself does. In IE7, it's even worse - the note div jumps down to under the toc and leaves a lot of empty space (2nd screenshot). So, how can I solve this? The ideal solution would have the note div occupy 100% of the visible space - i.e. it would resize itself to fit right next to the toc when needed. Any points appreciated. Thank you! Here are some screenshots for future reference: in IE7:

• Combining data sets without losing observations in SAS

  - by John

  Hye guys, I know, another post another problem :D :(. I took a screenshot to easily explain my problem. http://i39.tinypic.com/rhms0h.jpg As you can see I want to merge two tables (again), the Base & Analyst table. What I want to achieve is displayed in the right bottom corner table. I’m calculating the number of total analysts and female analysts for each month in the analyst table. In the base table I have different observations for one company (here company Alcoa with ticker AA). When I use the following command: data want; merge base analyst; by month ; run; I get the right up corner problem. My observations in the main table are being narrowed down to only 4 observations (for each different year one observation, 2001, 2002, 2005, 2006). What I want is that the observations are not reduced but that for every year the same data is being placed as shown in the right bottom corner. What am I missing in my merge command? In both tables I have month as a time count variable ( the observations in my base table are monthly) on which I need to merge. For clarity I added 2 screenshots of my real databases in SAS. The base table: http://i42.tinypic.com/dr5jky.jpg The analyst table: http://i40.tinypic.com/eqpmqq.jpg Here is what my merged table looks like: http://i43.tinypic.com/116i62s.jpg You can clearly see that the merged table only has four observations left for AA (one for each unique year) instead of the original 8. Anyone an idea to solve this?

• iPhone: Cell imageViews repeating when loaded from url

  - by araid

  I'm developing a demo RSS reader for iPhone. I obviously have a tableview to display the feeds, and then a detailed view. Some of this feeds have a thumbnail that I want to display on cell.imageview of the table, and some don't. The problem is that when scrolling the table, loaded thumbnails start repeating on other cells, and I end up with a thumbnail on every cell. Here's a piece of my code. I may upload screenshots later - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{ UITableViewCell * cell = [tableView dequeueReusableCellWithIdentifier: @"rssItemCell"]; if(nil == cell){ cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@"rssItemCell"]autorelease]; } BlogRss *item = [[[self rssParser]rssItems]objectAtIndex:indexPath.row]; cell.textLabel.text = [item title]; cell.detailTextLabel.text = [item description]; cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; // Thumbnail if exists if(noticia.imagePath != nil){ NSData* imageData; @try { imageData = [[NSData alloc]initWithContentsOfURL:[NSURL URLWithString:item.imagePath]]; } @catch (NSException * e) { //Some error while downloading data } @finally { item.image = [[UIImage alloc] initWithData:imageData]; [imageData release]; } } if(item.image != nil){ [[cell imageView] setImage:item.image]; } return cell; } Any help will be very appreciated.

• Processing RSS/RDF via xml.dom.minidom

  - by Bill

  I'm trying to process a delicious rss feed via python. Here's a sample: ... <item rdf:about="http://weblist.me/"> <title>WebList - The Place To Find The Best List On The Web</title> <dc:date>2009-12-24T17:46:14Z</dc:date> <link>http://weblist.me/</link> ... </item> <item rdf:about="http://thumboo.com/"> <title>Thumboo! Free Website Thumbnails and PHP Script to Generate Web Screenshots</title> <dc:date>2006-10-24T18:11:32Z</dc:date> <link>http://thumboo.com/</link> ... The relevant code is: def getText(nodelist): rc = "" for node in nodelist: if node.nodeType == node.TEXT_NODE: rc = rc + node.data return rc dom = xml.dom.minidom.parse(file) items = dom.getElementsByTagName("item") for i in items: title = i.getElementsByTagName("title") print getText(title) I would think this would print out each title, but instead I get basically get blank output. I'm sure I'm doing something stupid wrong, but no idea what?

• Pass Variable to Java Method from an Ant Target

  - by user200317

  At the moment I have a .properties file to store settings related to the framework. Example: default.auth.url=http://someserver-at008:8080/ default.screenshots=false default.dumpHTML=false And I have written a class to extract those values and here is the method of that class. public static String getResourceAsStream(String defaultProp) { String defaultPropValue = null; //String keys = null; try { InputStream inputStream = SeleniumDefaultProperties.class.getClassLoader().getResourceAsStream(PROP_FILE); Properties properties = new Properties(); //load the input stream using properties. properties.load(inputStream); defaultPropValue = properties.getProperty(defaultProp); }catch (IOException e) { log.error("Something wrong with .properties file, check the location.", e); } return defaultPropValue; } Throughout the application I use method like follows to just exact property needed, public String getBrowserDefaultCommand() { String bcmd = SeleniumDefaultProperties.getResourceAsStream("default.browser.command"); if(bcmd.equals("")) handleMissingConfigProperties(SeleniumDefaultProperties.getResourceAsStream("default.browser.command")); return bcmd; } But I have not decided do a change to this and use ant and pass a parameter instead of using it from .properties file. I was wondering how could I pass a value to a Java Method using ANT. Non of these classes have Main methods and will not have any main. Due to this I was unable to use it as a java system properties. Thanks in advance.

• Inconsistent height of text input elements between Firefox and WebKit

  - by Trevor Burnham

  OK, I realize that this is something of an eternal question, but here goes: I've got a single text input, <input type="text" name="whatever" /> and I've specified its font-family, font-size and padding. Yet, even on the same machine (my Mac, let's say), the input has a different height in Firefox (3.6) than it does in Chrome or Safari. Specifically, Firefox adds a little bit more padding below the text. And no, specifying height in pixels doesn't achieve consistency either. Is there any way to achieve text input height consistency across Gecko- and WebKit-based browsers (let alone IE and Opera) without resorting to JavaScript? And if I must use JavaScript, has someone already devised a jQuery plugin or something to easily do this? Update: Here's what not to do. The jqTransform plugin lets you skin form elements and promises that they'll look the same across browsers. Here's how the demo input looks in Chrome 5 on my Mac: and here's how the same input looks in Firefox 3.6.4: I haven't altered these screenshots in any way, just cropped them. Now, my first reaction is, "Ugh, I don't want to support Firefox." But there are currently more Firefox users than Safari and Chrome users combined, so that's not an option. Someone, please help! I just want my forms to look the same across modern, standards-compliant browsers! And by "look the same," I'm not talking about the outline on selection or anything like that; I'm just talking about having the same width, height, and text placement!

• Play framework does not return page and static content

  - by Anton

  I'm using play framework in production for one of my web projects. From time to time Play does not render main page or does not return some of the static content files. I have attached few screenshots below. First screenshot displays firebug console, loading of the site is stucked at the beginning, when serving home page. Second screenshot display fiddler console, when 2 static resources are not loading. This issue is hard to reproduce, it happens 1 of 15 time, I have to delete cache data and reload page. (pressing CRTL-F5 in FF). Issue can be reproduced in most of the browsers. Initially, I was thinging that there is something wrong with hosting provider. But I have changed hosting provided and issue has not gone. Version of the play is 1.2.2. Play is running as standalone server. Not sure, but probably deploying Play to Jetty/Tomcat/Resin would help. Also I'm thinging about rewriting application to another stack (well-known for me - j2ee, spring, whatever) I have no idea how to debug and resolve this issue. Any clue ? Has anyone faced same issue with Play before ?

• CSS Background image in Redmine template arbitrarily not loading

  - by Pekka

  I`m in the process of building a template for Redmine (a project management system based on Ruby on Rails.) Ruby is running on a virtual server from a Bitnami.org installation package. The OS is Windows. The template essentially consists of a styles.css file. In that file, I have the following line: #header { padding: 0px; padding-top: 48px; background-color: #62DFFF; background-image: url(../images/bkg.jpg) background-position: center bottom; background-repeat: repeat-x; height:150px; } It's a header element with a background image. The problem: This background image arbitrarily appears and disappears when reloading. Say you reload ten times in twenty seconds; the image will appear in two instances, and be missing in the 18 others. I would have put this down to server problems, but the weird thing is that when it's missing, the request for the image doesn't appear in Firebug's net tab at all. Even if it were cached, the request should be there. Raw screenshots of the identical page on two reloads: I am 100% sure the CSS file does not change in between. I have examined both instances with Firebug and the CSS is identical. It happens in both Firefox and Chrome so it must be something basic I'm overlooking. What could be causing a browser not to load a resource at all? I have zero idea about Ruby nor Rails - getting Redmine running and customized is all I have ever had to do with this platform - so I don't really know where to look. Apache's, Mongrel's and Redmine's error logs look fine, though.

• Providing lat/long AND title in iOS Maps URL seems to cause zoom level to be ignored

  - by Ian Howson

  I'm writing an iOS app that shows a location in Maps upon a user action. I'd like to drop a pin with a description and zoom in to show map detail. If I invoke Maps with the url http://maps.google.com/maps?q=-33.895851,151.18483+(Some+Description)&z=19 I get a pin with 'Some Description', but the zoom level is ignored. This does work on the Google Maps website. If I use http://maps.google.com/maps?q=-33.895851,151.18483&z=19 the zoom works, but I get no pin. I've tried a few combinations of ?q=, ?ll= and ?sll=, but so far, nothing will change zoom and show a description. Any clues? Just so we're really clear, here are some screenshots. I want this to work on a real device (i.e. with iOS Maps). The simulator uses Google Maps through Safari. Here's what I see with URL 1 ([[UIApplication sharedApplication] openURL:[NSURL URLWithString: @"http://maps.google.com/maps?q=-33.895851,151.18483+(Some+Description)&z=19"]];) This is URL 2 ([[UIApplication sharedApplication] openURL:[NSURL URLWithString: @"http://maps.google.com/maps?q=-33.895851,151.18483&z=19"]];): This is relikd's suggestion ([[UIApplication sharedApplication] openURL:[NSURL URLWithString: @"http://maps.google.com/maps?z=19&q=-33.895851,151.18483+(Some+Description)"]];): I want the image I see in screenshot 2, but with a pin and a description.

• Binding update on adds news series to WPF Toolkit chart (instead of replacing/updating series)

  - by Mal Ross

  I'm currently recoding a bar chart in my app to make use of the Chart class in the WPF Toolkit. Using MVVM, I'm binding the ItemsSource of a ColumnSeries in my chart to a property on my viewmodel. Here's the relevant XAML: <charting:Chart> <charting:ColumnSeries ItemsSource="{Binding ScoreDistribution.ClassScores}" IndependentValuePath="ClassName" DependentValuePath="Score"/> </charting:Chart> And the property on the viewmodel: // NB: viewmodel derived from Josh Smith's BindableObject public class ExamResultsViewModel : BindableObject { // ... private ScoreDistributionByClass _scoreDistribution; public ScoreDistributionByClass ScoreDistribution { get { return _scoreDistribution; } set { if (_scoreDistribution == value) { return; } _scoreDistribution = value; RaisePropertyChanged(() => ScoreDistribution); } } However, when I update the ScoreDistribution property (by setting it to a new ScoreDistribution object), the chart gets an additional series (based on the new ScoreDistribution) as well as keeping the original series (based on the previous ScoreDistribution). To illustrate this, here are a couple of screenshots showing the chart before an update (with a single data point in ScoreDistribution.ClassScores) and after it (now with 3 data points in ScoreDistribution.ClassScores): Now, I realise there are other ways I could be doing this (e.g. changing the contents of the original ScoreDistribution object rather than replacing it entirely), but I don't understand why it's going wrong in its current form. Can anyone help?

• Firefox extension: How to inject javascript into page and run it?

  - by el griz

  I'm writing a Firefox extension to allow users to annotate any page with text and/or drawings and then save an image of the page including the annotations. Use cases would be clients reviewing web pages, adding feedback to the page, saving the image of this and emailing it back to the web developer or testers taking annotated screenshots of GUI bugs etc. I wrote the annotation/drawing functionality in javascript before developing the extension. This script adds a <canvas> element to the page to draw upon as well as a toolbar (in a <div>) that contains buttons (each <canvas> elements) for the different draw tools e.g. line, box, ellipse, text, etc. This works fine when manually included in a page. I now need a way for the extension to: Inject this script into any page including pages I don't control. This needs to occur when the user invokes the extension, which can be after the page has loaded. Once injected the init() function in this script that adds the canvas and toolbar elements etc. needs to be run somehow, but I can't determine how to call this from the extension. Note that once injected I don't need this script to interact with the extension (as the extension just takes a screenshot of the entire document (and removes the added page elements) when the user presses the save button in the extension chrome).

• CasperJS Load next page in loop

  I've been working on a script which collates the scores for a list of user from a website. One problem is though, I'm trying to load the next page in the while loop, but the function is not being loaded... this.thenOpen("http://www.url.com?ul=" + currentName + "&sortdir=desc&sort=lastfound", function (id) { return function () { this.capture("Screenshots/" + json.username[id] + ".png"); if (!casper.exists(x("//*[contains(text(), 'That username does not exist in the system')]"))) { if (casper.exists(x('//*[@id="ctl00_ContentBody_ResultsPanel"]/table[2]'))){ this.thenEvaluate(tgsagc.tagNextLink); tgsagc.cacheCount = 0; tgsagc.continue = true; this.echo("------------ " + json.username[id] + " ------------"); while (tgsagc.continue) { this.then(function(){ this.evaluate(tgsagc.tagNextLink); var findDates, pageNumber; pageNumber = this.evaluate(tgsagc.pageNumber); findDates = this.evaluate(tgsagc.getFindDates); this.echo("Found " + findDates.length + " on page " + pageNumber); tgsagc.checkFinds(findDates); this.echo(tgsagc.cacheCount + " Caches for " + json.username[id]); this.echo("Continue?

• When I get the Force Close dialog, I have a Report button. Where did it come from?

  - by BenTobin

  I feel a little bit silly asking this, but I haven't been able to find any answers on my own. My Force Close dialog has a "Report" button. I think it's a great idea, and I wish everyone had it. At first, I thought it must be something I turned on without realizing it, but not only can't I find any setting that I might have touched, I also can't find any reference to this button existing on the Internet. I have a Droid, and I know 4 other people with Droids, and they say they don't have the option to report Force Closes. Am I special? Am I just missing something? The "report" button has been there for at least a few weeks now. When I use the Report button, I get a screen with a "feedback" field and a checkbox for "Include system data". Below that , it says "Information from feedback reports will be shown to the developer of the application." Under that are Preview and Send buttons. As a developer, I've never received one of these reports. I'd try to send a report to myself, but it seemingly only shows the button for apps installed from the market, and I don't know of a way to crash my production app. I suppose I could publish a simple crashing app just to try it out, but I thought I'd ask you folks first. Edit: You can view screenshots here: http://bentobin.com/crashReportImages/

• How Can I Compress Texture in OpenGL on iPhone/iPad?

  - by nonamelive

  Hi, I'm making an iPad app which needs OpenGL to do a flip animation. I have a front image texture and a back image texture. Both the two textures are screenshots. // Capture an image of the screen UIGraphicsBeginImageContext(view.bounds.size); [view.layer renderInContext:UIGraphicsGetCurrentContext()]; image = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); // Allocate some memory for the texture GLubyte *textureData = (GLubyte*)calloc(maxTextureSize*4, maxTextureSize); // Create a drawing context to draw image into texture memory CGContextRef textureContext = CGBitmapContextCreate(textureData, maxTextureSize, maxTextureSize, 8, maxTextureSize*4, CGImageGetColorSpace(image.CGImage), kCGImageAlphaPremultipliedLast); CGContextDrawImage(textureContext, CGRectMake(0, maxTextureSize-size.height, size.width, size.height), image.CGImage); CGContextRelease(textureContext); // ...done creating the texture data [EAGLContext setCurrentContext:context]; glGenTextures(1, &textureToView); glBindTexture(GL_TEXTURE_2D, textureToView); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR); glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, maxTextureSize, maxTextureSize, 0, GL_RGBA, GL_UNSIGNED_BYTE, textureData); // free texture data which is by now copied into the GL context free(textureData); Each of the texture takes up about 8MB memory, which is unacceptable for an iPhone/iPad app. Could anyone tell me how can I compress the texture to reduce the memory. I'm a complete newbie to OpenGL. Any help would be appreciated!

• What is the appropriate HTML 5 element for a hero unit/showcase?

  - by deb

  A lot of marketing and content-heavy sites showcase the page's primary content using large text and/or images, sometimes with a slider, containing a call to action for signing up for a service, or downloading an app, etc.. I'm not sure what this design element is called, I got the term hero unit from twitter bootstrap: http://twitter.github.com/bootstrap/components.html#typography I think most of you know what I'm trying to describe... If it's not clear I can add screenshots or links to this question. I looked at a few different sites, and some put this hero unit inside a ASIDE element, others use SECTION, ARTICLE and even HEADER. Using twitter bootstrap as an example again: <header class="jumbotron masthead"> <div class="inner"> <h1>Bootstrap, from Twitter</h1> <p>Simple and flexible HTML, CSS, and Javascript for popular user interface components and interactions.</p> <p class="download-info"> Is HEADER the most appropriate tag for this type of content? Or should I use ASIDE, ARTICLE or SECTION?

• Check for child duplicates

  - by ebb

  My console app will loop through each User to get their Websites, so that it can take new screenshots of them. However, to prevent taking screenshot of the same website twice I have to check whether there already has been taken screenshot of the website, while looping through another users websites. My current solution is: Database: User |--> ID: 1 |--> FirstName: Joe |--> ID: 2 |--> FirstName: Stranger Websites |--> ID: 1 |--> UserID: 1 |--> URL: http://site.com |--> ID: 2 |--> UserID: 2 |--> URL: http://site.com Console app: static void RenewWebsiteThumbNails() { Console.WriteLine("Starting renewal process..."); using (_repository) { var websitesUpdated = new List<string>(); foreach (var user in _repository.GetAll()) { foreach (var website in user.Websites.Where(website => !websitesUpdated.Contains(website.URL))) { _repository.TakeScreenDumpAndSave(website.URL); websitesUpdated.Add(website.URL); Console.WriteLine(new string('-', 50)); Console.WriteLine("{0} has successfully been renewed", website.URL); } } } } However, it seems wrong to declare a List for such a scenario, just to check whether a specific URL already has been added... any suggestions for an alternative way?

• Border of single th spreads to neighboring th when colspan set on td row below

  - by Samuel Hapak

  Having following html code: <table> <tr><th>First</th><th class='second'>Second</th><th class='third'>Third</th><th>Fourth</th></tr> <tr><td>Mike</td><td colspan=2 >John</td><td>Paul</td></tr> </table>? And following css: table { border-collapse: collapse; } td, th { border: 1px black solid; } td { border-top: none; } th { border-bottom: none; } th.second { border-bottom: 3px green solid; } th.third { } ? I would expect as result one table with 3px solid green line below the second th cell. Instead of that in Chrome, I have solid green border below both the second and the third th cell. In the firefox, results are just as expected. Is this browser bug, or my code is illegal? You can see example at http://jsfiddle.net/tt6aP/3/ PS: Try to set th.third { border-bottom: 2px solid red; } And then try to raise it to 3px. This is even more strange.

• Issue scrolling table view with content inset

  - by Rog

  Hi all, I am experiencing a weird scrolling issue and I was hoping someone could give me a hand in trying to identify why this is happening. I have included the part of my code that I think is relevant to the question but am happy to update this post with whatever else is needed. I have implemented a pull to refresh view in the tableview's content inset area. The refresh fires an Async NSURLConnection that pulls data from a webserver, parses the relevant information and refreshes the table as required. This is where the refresh process kicks off: - (void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate{ if (scrollView.contentOffset.y <= - 65.0f && !self.reloading) { self.reloading = YES; [self reloadTableViewDataSource]; [refreshHeaderView setState:EGOOPullRefreshLoading]; [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:0.2]; self.tableView.contentInset = UIEdgeInsetsMake(60.0f, 0.0f, 0.0f, 0.0f); [UIView commitAnimations]; } } Problem is if I start to scroll whilst the content inset is "visible" (i.e. during reload) I get this weird behaviour where my table sections do not scroll all the way to the top - see screenshot for a clear visual of what I am trying to describe here. I have included a couple of screenshots below that clearly identify what is happening at the moment. Has anyone experienced this before? Any ideas on what I should be looking at to try and fix it? Many thanks in advance, Rog And this is the result if I start scrolling the table. The orange bit at the top of the image is the actual navigation bar, where I would expect the table section (date 1 December 2010) to be.

• Defined outlets, connected them, they all returns (null)

  Hi! I'm trying to play with a WebView. I made an outlet: IBOutlet UIWebView *browser; Defined it as a property: @property (nonatomic, retain) IBOutlet UIWebView *browser; Synthethized it: @synthesize browser; Finally, I connected it in Interface Builder, really it is. Then I try to do something with it i.e.: [browser loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://apple.com"]]]; Or also: Etape *etape = [[Etape alloc] init]; NSString *html = [etape generateHTMLforEtape:[current_etape objectAtIndex:0]]; [browser loadHTMLString:html baseURL:nil]; [etape release]; I get no errors, I tried to Build & Analyse, no notices or warnings or errors.. I've been searching for one whole day, please help me :/ Thanks a lot! EDIT: Here's screenshots of my connections for my WebView: EDIT: That is how I call the view: DetailViewController *dvController = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:[NSBundle mainBundle]]; dvController.workflow_id = parent_id; Etape *etape = [[Etape alloc] init]; dvController.etapes = [etape getEtapes:parent_id]; [etape release]; [self.navigationController pushViewController:dvController animated:YES]; [dvController release];

• CodeIgniter - Image Validation & Thumbnailing

  - by Sebhael

  I'm currently trying to create a function that validates and creates thumbnails for images on upload - but I'm quite lost on what I'm doing. I'm assuming I'm off on my terminology so I'm not really getting any search results to help point me in the right direction. My playground is a form with 6 upload fields that are required. One of these fields is for a simple 32x32 icon image, another a portrait orientation (most likely) photo, and then 4 standard desktop screenshots -- and I'm using CodeIgniter as my framework. I would like to create a function that validates/thumbnails images, and only have to call it on the validation if at all possible. I know I can achieve this per-image, since the documentation for CI is quite through on this - but to reduce redundancy I'm looking for the better option. Outside of that, I don't even actually understand in full how to manipulate images unless it's just $this-input-post('field') - then calling all functions onto this? I don't know, I'm confused and posting on the actual CI forums has yielded me nothing - so all I'm really looking for is a point in the right direction to understanding what I'm trying to achieve here. This also all might not make any sense, I know it doesn't to me - but I can explain more if needed. Thanks in advance.

• UIWebView autosize issue only on iOS 4.3

  - by troop231

  I am trying to figure out how to fix this bug that only occurs on iOS 4.3. When the application launches, it displays a PDF that is scaled to fit in the UIWebView. It behaves perfectly until you pinch to zoom on the document, and then rotate it, leaving behind a black area. If you don't pinch to zoom, it doesn't leave the black area. I don't understand why this is a iOS 4.3 only issue. Screenshot of the issue: I've been trying to solve this problem awhile now, and would greatly appreciate your help. Thank you. Screenshots of the .xib settings: The code I'm using is: .h: #import <UIKit/UIKit.h> @interface ViewController : UIViewController { UIWebView *webView; } @property (nonatomic) IBOutlet UIWebView *webView; @end .m: #import "ViewController.h" @interface ViewController () @end @implementation ViewController @synthesize webView; - (BOOL)shouldAutorotateToInterfaceOrientation: (UIInterfaceOrientation)interfaceOrientation { if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) { return YES; } else { return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown); } } - (void)viewDidLoad { [super viewDidLoad]; NSString *urlAddress = [[NSBundle mainBundle] pathForResource:@"test" ofType:@"pdf"]; NSURL *url = [NSURL fileURLWithPath:urlAddress]; NSURLRequest *requestObj = [NSURLRequest requestWithURL:url]; [webView loadRequest:requestObj]; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; } @end

• Periodic GPU performance problem

  - by Peter Lillevold

  Hi folks! I have a WinForms application that uses XNA to animate 3D models in a control. The app have been doing just fine for months but recently I've started to experience periodic pauses in the animation. Setting out to investigate what is going on I have established these facts: It (currently) happens on my machine only Removing everything from my render loop does not improve the problem In 2. I didn't actually remove everything, I limited my loop to set the viewport on my GraphicsDevice and then do a GraphicsDevice.Present. Trying to dig further I fired up PIX to capture some statistics. Screenshots of two PIX runs can be viewed here (Run6) and here (Run14). Run6 is using my original render loop and Run14 is using the bare-bones Present loop. PIX tells me that the GPU is periodically doing something, and I assume this is causing the pauses. What could be the cause of this? Or how do I go about finding out what the GPU is actually doing? Note: I'm using XNA 3.1 on a Windows 7 x64 dual-core machine with 8GB RAM. Note2: also posted this question on the XNA Creators forums here.

• iPhone rotation woes

  - by skooter500

  I have been spending many frustrating hours trying to get rotations working on the iPhone version of Tunepal. Firstly, I have a tab bar controller, with a navigation controller controlling each of the views. I actually only want one of my views to be able to rotate and that is the TuneDisplay. I have a subclassed the UITabBarController and overridden theshouldAutorotateToInterfaceOrientation: (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation) interfaceOrientation { if (self.selectedViewController != nil) { return [self.selectedViewController shouldAutorotateToInterfaceOrientation:interfaceOrientation]; } else { return (interfaceOrientation == UIInterfaceOrientationPortrait); } } In each of the view controllers for each of the tabs I have overridden the method and returned YES for each orientation I want to support. All well and good and everything works as it should. If I try and do a rotation on a tab that doesn’t support the rotation, nothing happens. The problem occurs if I move from a tab thats rotated to a tab that isnt supposed to support that rotation. The new tab is displayed rotated too! Screenshots for all this are included here: http://tunepal.wordpress.com/2010/04/20/rotation-woes/ Is there any way I can make it rotate back to portrait on tapping the tab? I have tried the unsupported setOrientation trick, but firstly it doesnt work correctly and secondly I received a warning from Apple for including it in my last build. If (as I suspect) there is no way to limit this behavior: How do I make the microphone image scale when I rotate the device? How do I make the buttons and the progress bar expand to fit the witdh of the toolbar? Also, one of the tabs that rotates ok has a table, with a search bar. The first time I rotate to the right or to the left, I get a black bar to the right of the search bar. If I subsequently rotate back and rotate again, the bar disappears! I have enabled the struts and springs things on the search bar in the interface builder and it looks like it should behave correctly. Any ideas about how to fix this? Ideas, feedback much appreciated Bryan

• jQuery fade li elemet and cycle it when mouse hovered.

  - by Pennf0lio

  I'm trying to recreate an effect in jQuery, where an element(<li> <img>) will be cycled and has a fading effect when hovered. The '<li>' contains '<img>' (image screenshots). when the mouse is on top of element it will keep cycling all that are in '<ul>' with a fading effect. when the mouse is away it will stop cycling the list. I also want to add a pager where you can navigate to the list. My Existing Code: link text My Problem: The current code has some problem with the pagination, it added all images that can be seen on the code. instead of 1-8 only, it continued to add another 1-8 and another. Second problem is, It also start cycling and fading when the page loads. The cycling and fading should only be working when the mouse is on top of the element. I don't know if the 'Cycle Plugin' is really required on this approach, I wan't it to be minimal as much as possible. I just use 'Cycle Plugin' because it's a quick answer to my problem. The effect i'm trying to achieve: link text (WARNING: Contains some Pornography), Sorry of my example, I tried finding other alternative but no luck. Thanks and merry xmas!
