  • WebUIView is very slow

    - by Shamil
    Hello, I'm building a custom RSS reader app with incorporated feed link view (UIWebView). Using the following code, when the view, containing WebUIView is loaded, it takes about 6 seconds before anything is outputted to the user: -(void)viewDidLoad{ [super viewDidLoad]; NSString *urlString = [[[self appDelegate] currentlySelectedBlogItem]linkUrl]; NSURL *url = [NSURL URLWithString:urlString]; NSURLRequest *requestObj = [NSURLRequest requestWithURL:url]; [_webview loadRequest:requestObj]; [_webview setScalesPageToFit:YES]; } Any ideas why UIWebView is being so slow? I've checked the URL input, it's clean and what I'd expect it to be. I'm building for iOS 3.0 as base deployment target.

  • What can you do in the ant Task.init() method?

    - by skiphoppy
    I'm developing a few custom ant tasks that all need to initialize the same objects. I wanted to initialize those object's in a common superclass that extends from Task, in the init() method. But I see from the lifecycle of an ant task that init() gets called before the tasks child elements and attributes are set. So all of the data I need for initializing those objects is unavailable during init(), if I am reading right. So, why is init() called at this point? What do you even know that you could use in init()? What could it be used for? (And is there some other method that I can rely on to be called before execute(), but after my data is available?)

  • Rendering problem with UITableview

    - by Spider-Paddy
    I have a very strange problem with a UITableview within a navigation controller on the iPhone simulator. Of the cells displayed, only some are correctly rendered. They are all supposed to look the same but the majority are missing the accessory I've set, scrolling the view changes which cell has the accessory so I suspect it's some sort of cell caching happening, although the contents are correct for each cell. I also set an image as the background and that was also only displaying sporadically but I fixed that by changing cell.backgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"yellow-bar_short.png"]]; (which also only rendered a random cell with the background) to cell.backgroundColor = [[UIColor alloc] initWithPatternImage:[UIImage imageNamed:@"yellow-bar_short.png"]]; I now need to fix the problem with the accessory only showing on a random cell. I tried moving the code from cellForRowAtIndex to willDisplayCell but it made no difference. I put in a log command to confirm that it is running through each frame. Basically it's a table view (UITableViewCellStyleSubtitle) that gets its info from a server & is then updated by a delegate method calling reload. Code is: -(void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath { NSLog(@"%@", [NSString stringWithFormat:@"Setting colours for cell %i", indexPath.row]); // Set cell background // cell.backgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"yellow-bar_short.png"]]; cell.backgroundColor = [[UIColor alloc] initWithPatternImage:[UIImage imageNamed:@"yellow-bar_short.png"]]; cell.textLabel.backgroundColor = [UIColor clearColor]; cell.detailTextLabel.backgroundColor = [UIColor clearColor]; // detailTableViewAccessory is a view containing an imageview in this view's nib // i.e. nib <- view <- imageview <- image cell.accessoryView = detailTableViewAccessory; } // Called by data fetching object when done -(void)listDataTransferComplete:(ArticleListParser *)articleListParserObject { NSLog(@"Data parsed, reloading detail table"); self.currentTotalResultPages = (((articleListParserObject.currentArticleCount - 1) / 10) + 1); self.detailTableDataSource = [articleListParserObject.returnedArray copy]; // make a local copy of the returned array // Render table again with returned array data (neither of these 2 fixed it) [self.detailTableView performSelectorOnMainThread:@selector(reloadData) withObject:nil waitUntilDone:NO]; // [self.detailTableView reloadData]; // Re-enable necessary buttons (including table cells) letUserSelectRow = TRUE; [btnByName setEnabled:TRUE]; [btnByPrice setEnabled:TRUE]; // Remove please wait message NSLog(@"Removing please wait view"); [pleaseWaitViewControllerObject.view removeFromSuperview]; } I only included code that I thought was relevant, can supply more if needed. I can't test it on an iPhone yet so I don't know if it's maybe just a simulator anomaly or a bug in my code. I've always gotten good feedback from questions, any ideas?

  • iPhone - NSURLConnection does not receive data

    - by Jukurrpa
    Hi, I have a pretty weird problem with NSURLRequest. I'm using them to make an asynchronous image loading in an UITableView. The first time the tableView displays, all connections from NSURLRequests open correctly but receive absolutely no data, regardless of how long I wait. But as soon as I scroll down in the tableView, the newly created requests for the new cells work perfectly! The only way for the images on top of the tableView to load is to make them disappear by scrolling down and then up again, in order to create new requests. Here is what I do in "cellForRowAtIndexPath": UITableViewCell* cell = [tableView dequeueReusableCellWithIdentifier:@"Cell"]; if (cell == nil) { cell = [[UITableViewCell alloc] initWIthFrame:CGRectMake(0, 0, 300, 60)]; AsyncUIImageView imageView = [[AsynUIImageView alloc] initWithFrame:CGRectMake(0, 0, 60, 60)]; imageView.tag = IMG_VIEW // an enum for tags [cell addSubView:imageView]; [imageView release]; } AsyncUIImageView imageView = (AsyncUIImageView*)[cell viewWithTag:IMG_VIEW]; // I do a few cache checks here, but if the image aint cached I do this: [imageView loadImageFromURL:@"http://someurl.com/somepix.jpg"]; // all urls are different, just an example The AsyncUIImageView inherits from UIImageView and contains an NSURLConnection which opens upon calling the loadImageFromURL method: (void) loadImageFromURL:(NSString*)filename { if (self.connection != nil) [self.connection release]; if (self.data != nil) [self.data release]; NSURLRequest* request = [NSURLRequest requestWithURL:[[NSURL alloc] initWithString:fileName] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:10.0]; self.connection = [[NSURLConnection alloc] initWithRequest:request delegate:self]; if (self.connection == nil) return; self.data = [[NSMutableData data] retain]; } I've created the delegate methods "connection: didReceiveData", which appends received data to self.data and "connectionDidFinishLoading" which sets the image and closes the connection once the transfer is complete. These work, but are never called for the first requests I create. I suspect this bug to come from the main thread not giving the first requests the control so they can execute themselves, as the same behavior happens if I keep my finger on the screen after a scroll: connections open themselves, but no data is received until I stop touching the screen. What am I doing wrong?

  • How do you configure firefox to open an application without prompting the user?

    - by Peter
    I've got a serverside app that send down a custom mime-type file "application/x-optibase". Firefox prompt user user to save or open the file and if the user clicks open the correct application launches so I believe I have mimeType.rdf configured correctly I've gone into about:config and set browser.helperApps.neverAsk.openFile to application/x-optibase and browser.helpApps.alwaysAsk.force to false According to the minimal documentation out there this should enable the application to automatically open when the user downloads the file but it doesn't seem to work. Any ideas? Thanks.

  • Python 3-compatibe HTML to text converter preserving basic structure under permissive licence?

    - by hawk64
    I am looking for a relatively simple HTML to text converter which displays links and works on strings. So far I have tried lynx but performance is too bad, html2text which gives weird and verbose markdown output and is under GPLv3 which is too restrictive for my (BSD-licensed) project, http://effbot.org/librarybook/formatter-example-3.py using htmllib.HTMLParser with formatter.AbstractFormatter and a custom writer, however htmllib.HTMLParser is drpeceated and has been removed from Python 3. So is there any simple, performant, Python 3-compatible HTML to text converter under a permissive license such as MIT/BSD/Apache and the like? Edit: I dont just need something to strip HTML-Tags but also to preserve the basic structure of the HTML, that is output that somewhat resembles that of Lynx.

    My app is a very simple "one page" type app- It has Default.aspx I'm basically trying to get, for example: www.myappurl.com/this is my text I want to get hold of "this is my text" from the above example. This will be displayed on the page (for now) I didn't really want to have to use any complext url rewriting things for this...

  • Why is this CustomValidator client function not firing?

    - by xaisoft
    I have a dropdown with the Id of "BACKGROUND" and if nothing is selected or the value is other, it should fire my client side validation function, but it is not. Am I missing something? I have the following client side function: function cv26(oSrc, args) {//BACKGROUND,BG_OTHER alert("cv26"); var otherCtrl = document.getElementById("BG_OTHER"); args.IsValid = (args.Value != " ") || (otherCtrl.value.length > 0); } My Custom validator looks like this: <asp:CustomValidator ID="cv26" runat="server" ErrorMessage="26.

  • Android animation doesn't work, probably some kind of screen redraw problem.

    - by BenIOs
    I have created a custom component in my program by extending a ViewGroup. This component listens to touch events and are supposed to start animations when the user has move their finger past some certain points. I'm able to start animations while the user is touching the screen. But I'm not able to start animations if the user doesn't move their finger. It's probably that the phone thinks it doesn't have to update the screen if the user isn't moving their finger. I added some logs and according to them the animation starts and ends but it doesn't draw on the screen. I have the same problems when starting an animation with a timer. I use AlphaAnimations and TranslateAnimations on ImageViews. I have tried to use invalidate() both on the component and the ImageView but it doesn't help. Anyone who has an idea how to solve this?

  • Jsp cache problem

    - by idiotgenius
    I use javascript and css to build a multi-level drop down menu with following markups: <ul> <li>menu item 1</li> <ul> <li><a href="#">sub menu menu item 1</a></li> ................. This markup is generated by a custom JSTL tag <mui:menu .../> which loads menu data from a database. I hope my jsp page can behave like this: if menu data has not changed since last time I visited the page, just use browser's cache otherwise load from database... How can I do it? I don't know much detail about cache mechanism.

    Taking Sql this quarter and not having any luck with the following question: The height of players in feet (inches/12). Include their name. Hint: Calculation or derived field. Be sure to give the calculated field a column header. We're learning the basic Select statment and didn't find any reference on how to make custom data at w3schools. I'm using Microsoft SQL server Management Express Here's my statment so far: select nameLast, nameFirst, height from Master where height (I assume its something like 'Player_Height' = height/12) order by nameLast, nameFirst, height Thanks for the help

  • How to add JS/CSS files to Joomla modules?

    - by Apache Fan
    I am starting out with Joomla and am writing a simple Joomla module. I am using some custom CSS and JS in my module. Now when I distribute this module I need my JS/CSS files to go with the ZIP. I have added my files in my module ZIP file. This is what i need to know - How do I refer to these CSS/JS files in my module so that even if I distribute the module as a zip i would not have to send the css/js files separately? I tried looking at different solutions including http://www.howtojoomla.net/how-tos/development/how-to-add-cssjavascript-to-your-joomla-extension But I was not able to figure out what the URL for the JS/CSS file should be? I am using Joomla 1.7 hosted on a cloud hosting site. Thanks

  • Get list of running processes, get active process (and it's application) Flex/AIR

    - by Adam Kiss
    Hello, just a quickie (or maybe not:] ): Is it possible to get somehow list of running applications/processes and, while running in background, check which process is active? Additionally - if somehow, the answer was yes, is it possible to react for change of active window / application react just as if it was Event, or bind to it custom event (e.g. Event.SystemActiveAppChange)? Thank you for answers as well as pointers. EDIT: Due to probable missunderstanding, I mean local applications - on your win/mac/linux machine - I would like to (in process of learning of language) track what apps I use the most, make a little graph maybe? So, the point is: in AIR app, developed in FLEX, I would like to get/list all running applications/processes, as well as which one is active (on user's PC/Mac/Linux)

  • Secure to store an ID in an ASP.NET control ID?

    - by Curtis White
    I'm auto-generating a form in my ASP.NET page. This is already tested and working. I want to know if: If there are any security problems with storing the database ID as part of my controls ID? I can see think of 2 issues: the id will be visible in page source (not really important in this case), and the possibility someone could change the name of the control somehow? This second possibility is more serious. Is this a potential problem and how to void it? If there would be a better preferred way to associate a unique data with any type of control? Is it possible to store a custom item in the viewstate for the control?

  • Problem with JPopupMenu in a JTree

    - by Alex
    Hi guys I have this issue. In a custom JTree I implemented a JPopupMenu to display different JMenuItem according to the node selected using a MouseListener. The JPopupMenu is shown when the mouse right button is clicked. The problem is that if I don’t choose an Item from the PopupMenu but instead I select another node in the tree, either with right or left buttons, this event is never caught by the tree MouseListener Could anyone point me in the right direction to solve this? In case an example is available I’ll appreciate it. Thanks.

  • User Defined Class as a Template Parameter

    - by isurulucky
    Hi, I' m implementing a custom STL map. I need to make sure that any data type (basic or user defined) key will work with it. I declared the Map class as a template which has two parameters for the key and the value. My question is if I need to use a string as the key type, how can I overload the < and operators for string type keys only?? In template specialization we have to specialize the whole class with the type we need as I understand it. Is there any way I can do this in a better way?? What if I add a separate Key class and use it as the template type for Key? Thank You!!

  • Universal control - simple question about dock and anchor

    - by Vytas999
    I use Visual Studio .NET to develop internal applications. I create a Windows control that will display custom status bar information. Different developers will use the control to display the same information in many different applications. The control must always be displayed at the bottom of the parent form in every application. It must always be as wide as the form. When the form is resized, the control should be resized and repositioned accordingly. How should I do that in the best way and why? A)Create a property to allow the developers to set the Dock property of the control. Set the default value of the property to AnchorStyle.Bottom. B) Create a property to allow the developer to set the Anchor property of the control. Set the default value of the property to AnchorStyle.Bottom.

  • app.config and 64-bit machines

    - by Dale Lutes
    I have an app that works fine on 32-bit systems, but fails on XP 64 bit systems. I've tracked it down to the connection string defined in my app.config thus: <connectionStrings> <clear/> <add name="IFDSConnectionString" connectionString="Data Source=fdsdata;Initial Catalog=IFDS; Trusted_Connection=true;Connect Timeout=0" providerName="System.Data.SqlClient" /> </connectionStrings> When I try to reference it in code, I find that the ConfigurationManager.ConnectionStrings collection only contains the LocalSqlServer connection string from the machine.config file and not my custom string. Another oddity is that it works fine when I run the app out of Visual Studio. It is only when I run out of the release folder that the connection string does not get defined. The application's .exe.config file is there in the release folder along with the .exe file and is up to date.

  • Replacing text with a link in jQuery

    - by Eli
    I'm trying to replace a small part of text in a large HTML document with my own element which I create on the fly. The text may be a huge bulk of text, html, images, what-ever, and what I want is to find the first (or all) the position of a certain string, and replace it with an element that I create using $('< span'). Using simple text.replace('the string', $('< span')); doesn't do the trick (I'm left with [object Object] and not the actual < span that I want. The reason I don't just inject direct HTML is because I want to retain all the binds that are related to the object I'm creating. and doing a replace with a custom ID, and then attaching binds to the ID after the HTML has been altered, seems a bit dirty. Thanks for the help! :)

  • WPF layout calls MeasureOverride repeatedly in increments of 2?

    - by Scott Whitlock
    I've run into a case where I have a custom Panel (inherits from Panel) and I'm using it as an ItemsPanel in a ListView. When I resize the container that it's in, if I resize it smaller, my panel's MeasureOverride function gets called once, but if I resize it larger (let's say from 100 to 300), it calls MeasureOverride and ArrangeOverride for every value between 100 and 300, in increments of 2 (so 102, 104, etc.). The weird thing is that the container resizes right away (its size gets to 300 immediately). It doesn't seem to matter what I return from MeasureOverride - it just does this. I wish I could make it happen in a really small application and post it here, but I haven't been able to reproduce it like that yet. I can reproduce it all day in my app though. Does anyone know what could cause this?
