• Cannot display converted value inside xml field

  - by zurna

  PS: My bad, there was not an error. I forgot to upload the latest version to the server... I have multimedias and images table. I save images in multimedias table with their images table id numbers. Then whenever I need image's url, with a simple function I get it from images table. The problem I am having is when I try to display image's url inside ImageURL, it just does not happen. This is very annoying. xml output <?xml version='1.0' encoding='windows-1254' ?> <rows><row id='1'> <MultimediaTitle>Hagi Goals</MultimediaTitle> /FLPM/media/images/5Y2K4T5V_sm.jpg <ImageURL><![CDATA[]]></ImageURL> <Videos> <VideoID id='1'><VideoURL>/FLPM/media/videos/0H7T9C0F.flv</VideoURL></VideoID> <VideoID id='2'><VideoURL>/FLPM/media/videos/9L6X9G9J.flv</VideoURL></VideoID> </Videos> </row> </rows>

• Proper QUuid usage in Qt ? (7-Zip DLL usage problems (QLibrary, QUuid GUID conversion, interfaces))

  - by whipsnap

  Hi, I'm trying to write a program that would use 7-Zip DLL for reading files from inside archive files (7z, zip etc). Here's where I'm so far: #include QtCore/QCoreApplication #include QLibrary #include QUuid #include iostream using namespace std; #include "7z910/CPP/7zip/Archive/IArchive.h" #include "7z910/CPP/7zip/IStream.h" #include "MyCom.h" // {23170F69-40C1-278A-1000-000110070000} QUuid CLSID_CFormat7z(0x23170F69, 0x40C1, 0x278A, 0x10, 0x00, 0x00, 0x01, 0x10, 0x07, 0x00, 0x00); typedef int (*CreateObjectFunc)( const GUID *clsID, const GUID *interfaceID, void **outObject); void readFileInArchive() { QLibrary myLib("7z.dll"); CreateObjectFunc myFunction = (CreateObjectFunc)myLib.resolve("CreateObject"); if (myFunction == 0) { cout outArchive; myFunction(&CLSID_CFormat7z, &IID_IOutArchive, (void **)&outArchive); } int main(int argc, char *argv[]) { QCoreApplication a(argc, argv); readFileInArchive(); return a.exec(); } Trying to build that in Qt Creator will lead to following error: cannot convert 'QUuid*' to 'const GUID*' in argument passing How should QUuid be correctly used in this context? Also, being a C++ and Qt newbie I haven't yet quite grasped templates or interfaces, so overall I'm having trouble getting through these first steps. If someone could give tips or even example code on how for example an image file could be extracted from ZIP file (to be shown in Qt GUI later on*), I would highly appreciate that. My main goal at the moment is to write a program with GUI for selecting archive files containing image files (PNG, JPG etc) and displaying those files one at a time in the GUI. A Qt based CDisplayEx in short.

• Converting Source ASCII Files to JPEGs

  - by CommonsWare

  I publish technical books, in print, PDF, and Kindle/MOBI, with EPUB on the way. The Kindle does not support monospace fonts, which are kinda useful for source code listings. The only way to do monospace fonts is to convert the text (Java source, HTML, XML, etc.) into JPEG images. More specifically, due to pagination issues, a given input ASCII file needs to be split into slices of ~6 lines each, with each slice turned into a JPEG, so listings can span a screen. This is a royal pain. My current mechanism to do that involves: Running expand to set a consistent 2-space tab size, which pipes to... a2ps, which pipes to... A small Perl snippet to add a "%%LanguageLevel: 3\n" line, which pipes to... ImageMagick's convert, to take the (E)PS and make a JPEG out it, with an appropriate background, cropped to 575x148+5+28, etc. That used to work 100% of the time. It now works 95% of the time. The rest of the time, I get convert: geometry does not contain image errors, which I cannot seem to get rid of, in part because I don't understand what the problem is. Before this process, I used to use a pretty-print engine (source-highlight) to get HTML out of the source code...but then the only thing I could find to convert the HTML into JPEGs was to automate screen-grabs from an embedded Gecko engine. Reliability stank, which is why I switched to my current mechanism. So, if you were you, and you needed to turn source listings into JPEG images, in an automated fashion, how would you do it? Bonus points if it offers some sort of pretty-print process (e.g., bolded keywords)! Or, if you know what typically causes convert: geometry does not contain image, that might help. My current process is ugly, but if I could get it back to 100% reliability, that'd be just fine for now. Thanks in advance!

• Have something loaded only when JList item is visibile

  - by elvencode

  Hello, i'm implementing a Jlist populated with a lot of elements. Each element corresponds to a image so i'd like to show a resized preview of them inside each row of the list. I've implemented a custom ImageCellRenderer extending the Jlabel and on getListCellRendererComponent i create the thumbnail if there'snt any for that element. Each row corresponds to a Page class where i store the path of the image and the icon applied to the JLabel. Each Page object is put inside a DefaultListModel to populate the JList. The render code is something like this: public Component getListCellRendererComponent( JList list, Object value, int index, boolean isSelected, boolean cellHasFocus) { Page page = (Page) value; if (page.getImgIcon() == null) { System.out.println(String.format("Creating thumbnail of %s", page.getImgFilename())); ImageIcon icon = new ImageIcon(page.getImgFilename()); int thumb_width = icon.getIconWidth() > icon.getIconHeight() ? 128 : ((icon.getIconWidth() * 128) / icon.getIconHeight()); int thumb_height = icon.getIconHeight() > icon.getIconWidth() ? 128 : ((icon.getIconHeight() * 128) / icon.getIconWidth()); icon.setImage(getScaledImage(icon.getImage(), thumb_width, thumb_height)); page.setImgIcon(icon); } setIcon(page.getImgIcon()); } I was thinking that only a certain item is visibile in the List the cell renderer is called but i'm seeing that all the thumnails are created when i add the Page object to the list model. I've tried to load the items and after set the model in the JList or set the model first and after starting appending the items but the results are the same. Is there any way to load the data only when necessary or do i need to create a custom control like a JScrollPanel with stacked items inside where i check myself the visibility of each elements? Thanks

• What is the best way to do scoped finds based on access control rules in Rails?

  - by Rafael Szuminski

  Hi I need to find an elegant solution to scoped finds based on access control rules. Essentially I have the following setup: Users Customers AccessControl - Defines which user has access to another users data Users need to be able to access not just their own customers but also shared customers of other users. Obviously something like a simple association will not work: has_many :customers and neither will this: has_many :customers, :conditions => 'user_id in (1,2,3,4,5)' because the association uses with_scope and the added condition is an AND condition not an OR condition. I also tried overriding the find and method_missing methods with the association extension like this: has_many :customers do def find(*args) #get the user_id and retrieve access conditions based on the id #do a find based on the access conditions and passed args end def method_missing(*args) #get the user_id and retrieve access conditions based on the id #do a find based on the access conditions and passed args end end but the issue is that I don't have access to the user object / parent object inside the extension methods and it just does not work as planned. I also tried default_scope but as posted here before you can't pass a block to a default scope. Anyhow, I know that data segmentation and data access controls have been done before using rails and am wondering if somebody found an elegant way to do it. UPDATE: The AccessControl table has the following layout user_id shared_user_id The customer table has this structure: id account_id user_id first_name last_name Assuming the the following data would be in the AccessControl table: 1 1 1 3 1 4 2 2 2 13 and so on... And the account_id for user 1 is 13 I need to be able to retrieve customers that can be best described with the following sql statement: select * from customers where (account_id = 13 and user_id = null) or (user_id in (1,3,4))

• Is it possible to pull a webpage or content from the web into a widget on the android home screen

  - by cdg

  Hi there. I have a php web page that will randomize an image that is 158x154. I was able to get the android application to work, but would also like to get it to work as a widget. How the heck can I get a widget to pull information from the net? I got the widget to work and layout correctly with a black sample image. I have tried to look at the wiki sample, but it is a bit too complicated for my little brain to grasp. The data that gets pulled looks something like: <html><body bgcolor="#000000">center> <a href="http://www.website.com" target="_blank"> <img border="0" src="http://www.webiste.com//0.gif"></a> <img src="http://www.webiste.com" style="border:none;" /> </center></body></html> Help please. I am pulling my hair out trying to figure this out.

• SASS mixin for swapping images / floats on site language (change)

  - by DBUK

  Currently using SASS on a website build. It is my first project using it, tried a little LESS before and liked it. I made a few basic mixins and variables with LESS, super useful stuff! I am trying to get my head around SASS mixins, and syntax, specifically for swapping images when the page changes to a different language, be that with body ID changing or <html lang="en">. And, swapping floats around if, for example, a website changed to chinese. So a mixin where float left is float left unless language is AR and then it becomes float right. With LESS I think it would be something like: .headerBg() when (@lang = en) {background-image:url(../img/hello.png);} .headerBg() when (@lang = it) {background-image:url(../img/ciao.png);} .header {.headerBg(); width: 200px; height:100px} .floatleft() when (@lang = en) { float: left;} .floatleft() when (@lang = ar) { float: right;} .logo {.floatleft();} Its the syntax I am having problems with combined with a brain melting day.

• Why is this unordered list formatting differently in IE7?

  - by Joel

  I'm better about getting things to look good in IE8, FF, and Safari, but IE7 still throws curve balls at me... Please check out this page and scroll down below the nav bar: http://rattletree.com/instruments.php It should become obvious when viewing in FF vs IE7. For some reason the formatting of the list is pushing the list items down on the page... any tips? <ul class="instrument"> <li class="imagebox"><img src="/images/stuff.jpg" width="247" height="228" alt="Matepe" /></li> <li class="textbox"><h3>Matepe</h3><p>This text should be to the right of the image but drops below the image in IE7</p></li> </ul> css: ul.instrument { text-align:left; display:inline-block; } ul.instrument li { list-style-type: none; display:inline-block; } li.imagebox { display:inline; margin:20px 0; padding:0px; vertical-align:top; } li.imagebox img{ border: solid black 1px; } li.textbox { display:inline; } li.textbox p{ margin:10px; width:340px; display:inline-block; }

• Rebuilding old (2010) django project in 2012

  - by birgit

  I am trying to make an old Django project run again. After seemingly having solved issues with old sorl.thumbnail versions and deprecated expressions I now get this error when running python manage.py runserver I also tried to copy & paste my old files into a new Django project and get the exactly same error.

• CSS to specify positions over a scanned document

  - by itsols

  I'm trying to write the CSS rules to position text over a scanned document. Reason: The document is a pre-printed form. I am trying to position the text on-screen so that it relates to the 'spaces' on the actual form. Issue: Although I position the values using centimeters, they don't seem to get aligned with the ones on the actual page. I can see this misalignment since my scanned image is in the background of the page. What I've tried: I used a ruler to physically measure the locations and specify them with CSS. But on-screen, it doesn't tally. I used the scanned image to position the CSS values. Then the printout is not correct. I even scaled the scanned page using Inkscape to the exact dimensions in centimeters and took into account all margins, etc... What I need: I am trying to correctly show the output values on-screen AND have them print in the correct manner as well. I know that using two CSS sheets (one for print) is an option. But I'm developing this program away from where the actual printing is to be done. So is there a convenient way of matching the exact screen locations with those on the actual/final prinout? Thanks!

• jQuery Ajax call for buttons on a list

  - by lloydphillips

  I have a list of data that i have in a view from an asp.net mvc application. It's a list of stock and I have two images (a plus and a minus) on the end of each row which will allow me to increase or decrease stock quantity. It works fine at present with a call to the mvc action but since the list is long I want to use jQuery and AJAX to have the call go without a refresh. I want to do this with unobtrusive javascript so don't want onclick handlers on my images. Since I'm just starting out with jQuery I have no idea how I can iterate all the images and add the function. Here are the images with the form tags as they stand: <td> <% using (Html.BeginForm("Increase", "Stock", new { Id = item.StockId })) {%> <input type="image" src="/Content/Images/bullet_add.png" style="margin-left:20px;" /> <% } %> </td> <td><% using (Html.BeginForm("Decrease", "Stock", new { Id = item.StockId })) {%> <input type="image" src="/Content/Images/bullet_delete.png" style="margin-left:10px;" /><% } %> </td> Can anyone help me out a little? Many thanks. Lloyd

• Cannot change font size /type in plots

  - by Sameet Nabar

  I recently had to re-install my operating system (Ubuntu). The only thing I did differently is that I installed Matlab on a separate partition, not the main Ubuntu partition. After re-installing, the fonts in my plots are no longer configurable. For example, if I ask the title font to be bold, it doesn't happen. I ran the sample code below on my computer and then on my colleague's computer and the 2 results are attached. This cannot be a problem with the code; rather in the settings of Matlab. Could somebody please tell me what settings I need to change? Thanks in advance for your help.

• How can I get HTML to link to a browser (or system) specified URL?

  - by MrHatken

  Hi All, I'd like to be able to create a "HTML link" that the user can click on and be taken to an URL (location) specified either in the browser (preferences?) or system environment. Is this possible? Any suggestions on how to do it please? For example, it may look something like this (or alternatively it could be a clickable image or even a submit button): "Click here to go to your preferred news site." When the user clicks on "here" the browser would go to a location specified not in the HTML but somehow in the browser (preferences?) or some system environment variable (OS specific etc.) Of course, the user would have to set up this preference or environment variable (or have some local application or better Web page that could set it - when approved by the user). This is sort of like most OS these days allow you to set "preferred app" for image processing or playing media. I would like to set preferred Web sites for certain tasks. Thanks for any suggestions. Hopefully with Javascript and modern browsers and perhaps HTML 5 something like this is possible. Cheers, Ashley.

• How would I combine these two codes, PHP and HTML?

  - by user1887109

  This is what I have currently: <html> <body oncontextmenu="return false;" bgcolor="5385ab"> <p align=center><a href="test.php"><img src="image.png"/></a></p> </body> </html> I need the <body> part and to combine this PHP geo-redirect code with "test.php" also including the "image.png" Here is the PHP code: <?php require_once("geoip.inc"); $gi = geoip_open("/var/lib/GeoIP/GeoIP.dat",GEOIP_STANDARD); $country_code = geoip_country_code_by_addr($gi, $_SERVER['REMOTE_ADDR']); geoip_close($gi); if($country_code == 'FR') { header('Location: http://www.test.php'); } else { header('Location: http://www.yahoo.com/'); } ?> I'm not familiar with PHP so I have no idea how to even go about testing these two together. Hope you can help! Thank you.

• How do I distribute my slightly customized Linux in VirtualBox?

  - by goodrone

  Suppose I've got some Arch Linux installation which I'd like to distribute among students with (sometimes very) basic Linux knowledge to make them able to compile C programs in an environment very similar to that in the university. (Things like Cygwin or MinGW seem to be inappropriate here.) I also choose VirtualBox as a holder for the virtual system. The question is: how do I distribute it? I mean: installing VirtualBox on the target machine (if not still installed) uncompressing and copying my image file (.VDI) registering the image (so that VirtualBox could see it when launched) configuring the guest system in VirtualBox (network, memory, etc.) optionally installing PuTTY to simplify interfacing with the guest Linux Should I create an installer? Which one? Or just write some .BAT-scripts? (Target host system is Windows, mostly XP and Vista.) I definately don't want to have a webpage with screen shot explaining where to click and what to press, because it's boring. Additionaly, what will be the best (the most user-friendly) way to configure network when the guest Linux system is run for the first time?

• Cannont Update control in WPF custom control

  - by Fazi

  I have created a custom control which holds a button in it. The button is styled, so as to hold a grid with two rows, an image in the first and a TextBlock in the second. I have written an Event Handler for the custom control. When the mouse enters the path of the object the MouseEnter event fires, where I try to change the TextBlock's FontSize and Foreground color, however the control does not update. In contrast, I have tried to modify an regular TextBlock's(not part a custom control and controltemplate) properties, and they update correctly, on the fly. What am I missing here?? Here is the code for the event handler: private void ThemeButton_MouseEnter(object sender, MouseEventArgs e) { InitializeProperties(); TextElement.FontSize = 16; TextElement.Text = "new text"; TextElement.Foreground = Brushes.Red; TextBlock element = MainWindow.FindChild<TextBlock>(MainWindow.StartWindow, "textField"); element.Text = "new text for regular textblock"; element.Foreground = Brushes.Red; } InitializeProperties is a methid that initializes TextElement(typeof TextBlock) and ImageElement(typeof Image) properties. They are not null. The properties are just regular .NET properties.

• Why would the same web form control render different "onclick" logic based on the page structure?

  - by zk812

  It was hard to title this question. :) I have a user control that is used to display a list of lookup items in my database and a delete button for each item (Editor User Control below). The delete button has an onClientClick event used to display a confirmation dialog in JavaScript. On page one, the confirmation pops up and functions correctly. The overall structure is: Master Page Page Editor User Control List of items with delete button On page two, the confirmation pops up but regardless of the answer, the page posts back anyway. The structure of this page is: Master Page Page User Control Editor User Control List of items with delete button For some reason, this makes a difference in how the delete button is rendered. Page one: <input type="image" name="ctl00...RequestTypesDataList$ctl01$ctl01" src="Images/Disable.png" alt="Delete" onclick="return ProcessDeleteCommand(1);" /> Page two: <input type="image" name="ctl00...RequestTypesDataList$ctl07$ctl01" src="Images/Disable.png" alt="Delete" onclick="return ProcessDeleteCommand(2);WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions(&quot;ctl00$ContentPlaceHolder1$RequestCreator1$RequestTypeEditor1$RequestTypesDataList$ctl07$ctl01&quot;, &quot;&quot;, true, &quot;&quot;, &quot;&quot;, false, false))" /> Does anyone know why page two renders WebForm_DoPostBackWithOptions after my JS check? It's causing the postback regardless of the confirmation choice.

• Android - BitmapFactory.decodeByteArray - OutOfMemoryError (OOM)

  - by Bob Keathley

  I have read 100s of article about the OOM problem. Most are in regard to large bitmaps. I am doing a mapping application where we download 256x256 weather overlay tiles. Most are totally transparent and very small. I just got a crash on a bitmap stream that was 442 Bytes long while calling BitmapFactory.decodeByteArray(....). The Exception states: java.lang.OutOfMemoryError: bitmap size exceeds VM budget(Heap Size=9415KB, Allocated=5192KB, Bitmap Size=23671KB) The code is: protected Bitmap retrieveImageData() throws IOException { URL url = new URL(imageUrl); InputStream in = null; OutputStream out = null; HttpURLConnection connection = (HttpURLConnection) url.openConnection(); // determine the image size and allocate a buffer int fileSize = connection.getContentLength(); if (fileSize < 0) { return null; } byte[] imageData = new byte[fileSize]; // download the file //Log.d(LOG_TAG, "fetching image " + imageUrl + " (" + fileSize + ")"); BufferedInputStream istream = new BufferedInputStream(connection.getInputStream()); int bytesRead = 0; int offset = 0; while (bytesRead != -1 && offset < fileSize) { bytesRead = istream.read(imageData, offset, fileSize - offset); offset += bytesRead; } // clean up istream.close(); connection.disconnect(); Bitmap bitmap = null; try { bitmap = BitmapFactory.decodeByteArray(imageData, 0, bytesRead); } catch (OutOfMemoryError e) { Log.e("Map", "Tile Loader (241) Out Of Memory Error " + e.getLocalizedMessage()); System.gc(); } return bitmap; } Here is what I see in the debugger: bytesRead = 442 So the Bitmap data is 442 Bytes. Why would it be trying to create a 23671KB Bitmap and running out of memory?

• Windows 7 Mobile ListBox uncustomizable?

  - by Roy

  I've just recently started development using Visual Studio 2010 Express for Windows Phone and I put in a ListBox. I can't seem to manipulate the formatting. No matter what I do, the background is black/gray, the selected items have a blue border, and there is padding between the items in the listbox (i'm using images). Here is my code: Xaml: <Grid x:Name="ContentGrid" Grid.Row="1"> <Grid Name="gallery"> <Grid.RowDefinitions> <RowDefinition Height="370" /> <RowDefinition Height="150" /> </Grid.RowDefinitions> <Border BorderBrush="Red" Width="450" CornerRadius="4" BorderThickness="2" Background="Red" Margin="10,30,20,10" Padding="6,6,6,6"> <Image Grid.Row="0" Grid.Column="0" Height="360" x:Name="imgPreview"/> </Border> <ListBox x:Name="lbScrollGallery" Grid.Row="1" Grid.Column="0" Padding="0" VerticalAlignment="Top" Width="450" SelectionChanged="ScrollerSelectionChanged" d:LayoutOverrides="HorizontalAlignment" ScrollViewer.HorizontalScrollBarVisibility="Hidden"> <ListBox.ItemsPanel> <ItemsPanelTemplate> <StackPanel Orientation="Horizontal"/> </ItemsPanelTemplate> </ListBox.ItemsPanel> <ListBox.ItemTemplate> <DataTemplate> <Image Width="100" Height="100" Stretch="Fill" Name="imgSource" VerticalAlignment="Center" Source="{Binding Path=Url}" /> </DataTemplate> </ListBox.ItemTemplate> </ListBox> </Grid> </Grid> Is there some way I can customize the listbox? Like change the background to red or make the padding between different items 0?

When I execute class B, I got this error, java.lang.NullPointerException at A.test_Login(A.java:32) at B.test_kk(savefile.java:58) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at junit.framework.TestCase.runTest(TestCase.java:168) at junit.framework.TestCase.runBare(TestCase.java:134) at com.thoughtworks.selenium.SeleneseTestCase.runBare(SeleneseTestCase.j ava:212) at junit.framework.TestResult$1.protect(TestResult.java:110) at junit.framework.TestResult.runProtected(TestResult.java:128) at junit.framework.TestResult.run(TestResult.java:113) at junit.framework.TestCase.run(TestCase.java:124) at junit.framework.TestSuite.runTest(TestSuite.java:232) at junit.framework.TestSuite.run(TestSuite.java:227) at junit.textui.TestRunner.doRun(TestRunner.java:116) at junit.textui.TestRunner.doRun(TestRunner.java:109) at junit.textui.TestRunner.run(TestRunner.java:77) at B.main(B.java:77) I hope someone must have tried this before. I may miss something here.

• Canvas maximization bug?

  - by mitjak

  I must've killed over an hour on what seems to me like strange behaviour that happens in Firefox, Safari and Chrome. Here is some code: <!doctype html> <html> <head> <title>Watch me grow scrollbars!</title> </head> <body onload="resizeCanvas()"> <canvas id="canvas"></canvas> </body> </html> <script type="application/javascript"> function resizeCanvas() { var canvas = document.getElementById("canvas"); canvas.setAttribute("height", window.innerHeight); canvas.setAttribute("width", window.innerWidth); } </script> Basically, the canvas always seems to maximize 'too much', and the window grows scrollbars on both sides. I've tried using various ways of obtaining the document dimensions, including nesting canvas in a 100% wide & tall absolutely positioned div, as well as extracting the document.documentElement.clientWidth/Height properties. Just to be sure I'm not going insane, I've placed an image in place of the canvas, and voila, the same code worked perfectly to stretch the image out to document dimensions. What am I doing wrong here? I'm too tired to understand. Must.. drink.. something.

• how can you have the same form handle by javascript multiple times on the same page?

  - by DeChamp

  I have a thumb gallery where I am using ajax/javascript to submit a form per image to report the image as broken seamlessly along with php. The form and script is templated so the script is in the header and then the form is printed multiple times on the same page with a hidden field with a different id for the value per thumb. So basically this is what i have. javascript in header just a quick idea of the forms i have. Just a quick idea not what I actually have. image1 followed by the form image2 followed by the form So when you hit the button it basically submits all of the forms at the same time. I am sure it can be fixed with a (this) or something like that so it only submits a single form at a time. Let me know please. $(function() { $(".submit").click(function() { var imgId = $("#imgId").val(); var dataString = 'imgId='+ imgId; if(imgId==''){ $('.success').fadeOut(200).hide(); $('.error').fadeIn(200).show(); $('.error').fadeOut(200).hide(); }else{ $.ajax({ type: "POST", url: "inc/brokenImgReport.php", data: dataString, success: function(){ }); $('.error').fadeOut(200).hide(); $('.success').fadeIn(200).show(); setTimeout(function() { $('.success').fadeOut(200); }, 2000); } return false; }); });

• How to "reset" subviews of scrollview for new items?

  - by Tom Tallak Solbu

  I have a MasterViewController displaying Items. Selecting an Item (ItemA), displays images of ItemA in a DetailViewController. The DeatilViewController contains a scrollView, displaying all the images. When tableView:didSelectRowAtIndexPath is called, the images is added to an UIImageView, that is tagged and added as a subview to a scrollview. NSUInteger i; for (i = 1; i <= numberOfImages; i++) { NSString *imageName = [ItemAImages objectAtIndex:i-1]; UIImage *image = [UIImage imageNamed:imageName]; UIImageView *imageView = [[UIImageView alloc] initWithImage:image]; imageView.tag = i; [scrollView addSubview:imageView]; } Works fine. But when I go back to the MasterViewController, and selects a ItemB, the ItemA is still displayed, like the iPhone simulator refuses to forget the previous scrollview,containing ItemA images. I have tried [subview removeFromSuperview]; which results in either no scrollview at all, or no effect. Depending on when this method is called. How can I "reset" the scrollview for the next Item?

• inconsistent setTexture behavior in cocos2d on iPhone after using CCAnimate/CCAnimation

  - by chillid

  Hi, I have a character that goes through multiple states. The state changes are reflected by means of a sprite image (texture) change. The state change is triggered by a user tapping on the sprite. This works consistently and quite well. I then added an animation during State0. Now, when the user taps - setTexture gets executed to change the texture to reflect State1, however some of the times (unpredictable) it does not change the texture. The code flows as below: // 1. // Create the animation sequence CGRect frame1Rect = CGRectMake(0,32,32,32); CGRect frame2Rect = CGRectMake(32,32,32,32); CCTexture2D* texWithAnimation = [[CCTextureCache sharedTextureCache] addImage:@"Frames0_1_thinkNthickoutline32x32.png"]; id anim = [[[CCAnimation alloc] initWithName:@"Sports" delay:1/25.0] autorelease]; [anim addFrame:[CCSpriteFrame frameWithTexture:texWithAnimation rect:frame1Rect offset:ccp(0,0)]]; [anim addFrame:[CCSpriteFrame frameWithTexture:texWithAnimation rect:frame2Rect offset:ccp(0,0)]]; // Make the animation sequence repeat forever id myAction = [CCAnimate actionWithAnimation: anim restoreOriginalFrame:NO]; // 2. // Run the animation: sports = [[CCRepeatForever alloc] init]; [sports initWithAction:myAction]; [self.sprite runAction:sports]; // 3. stop action on state change and change texture: NSLog(@"Stopping action"); [sprite stopAction:sports]; NSLog(@"Changing texture for kCJSports"); [self setTexture: [[CCTextureCache sharedTextureCache] addImage:@"SportsOpen.png"]]; [self setTextureRect:CGRectMake(0,0,32,64)]; NSLog(@"Changed texture for kCJSports"); Note that all the NSLog lines get logged - and the texture RECT changes - but the image/texture changes only some of the times - fails for around 10-30% of times. Locking/threading/timing issue somewhere? My app (game) is single threaded and I only use the addImage and not the Async version. Any help much appreciated.
