• a question about flex preloaders

  - by dubbeat

  Hi, I'm moving to a pure as3 environment into flex and I have a question about preloaders. For one of my apps in particular when the swf loaded I would add a screen with an animated preloader. Then at a particular point in my code when I know all of my xml has been parsed, UI built and all initiliztion done I dispatch a "done" event which removes the preloader. How can I achieve this is flex? I've only ever really seen flex preloaders that are percentage based which I believe represent the actual loading of the swf itself?

• Problem with events and ParseControl

  - by Richard Edwards

  I'm adding a control (linkbutton) dynamically using ParseControl and it's fine except when I specify an event handler. If I use: Dim c As Control = ParseControl("<asp:LinkButton id=""btnHide"" runat=""server"" text=""Hide"" OnClick="btnHide_Click" />") it correctly adds the control to the page but the click event doesn't fire. If instead I find the control in the controls collection and manually wire up the event it works fine. I've tried loading in both Page_Init and Page_Load and it's the same thing either way. Any ideas?

• Avoid application becoming unresponsive on download

  - by baron

  Hi I have an application which downloads a file from a network location and then displays that files information. It uses WebClient.DownloadFile to achieve this. The problem is, when the user clicks a button to start the download, the application becomes unresponsive until the file has downloaded. This gives the impression the application may have hung. I would like to seek ideas which would avoid this scenario. Though my solution will need to be 'as quick and cheap as possible' I would be interested in hearing about custom loaders that have been built, or some sort of loading symbol / progress bar / sand time clock thingy : ) Thanks for reading.

• How to rotate an image properly in JPanel (Java)

  - by Bruce

  Hi guys, I'm working on rotating a loaded image. I set the graphics on a JPanel and then use standard AffineTransform in order to rotate it, say, 45 degrees. Unfortunately, the image is being cut, if it exceeds the panel area. How may I force JPanel to add scrolls to itself (while loading an image file, I would like to adjust the size of JPanel by adding the scrolls, without adjusting the size of JFrame). Or, in other words, how to correctly rotate the whole image? Thank you in advance for the reply!

• Textures loaded with NSOperation are blank

  - by Omega

  So I call this method: -(void)beginExecution { NSOperationQueue *queue = [NSOperationQueue new]; NSInvocationOperation *operation = [[NSInvocationOperation alloc] initWithTarget:self selector:@selector(execute) object:nil]; [queue addOperation:operation]; [operation release]; } Which triggers this: -(void)execute { [[CCSpriteFrameCache sharedSpriteFrameCache]addSpriteFramesWithFile:@"MyTexture.plist"]; loaded = YES; // This tells me whenever loading is done. } However, when I create a sprite and try to use the texture MyTexture.png, the sprite is a blank canvas. Why is that?

• audio error in vmware running mac os x

  - by PenguinSource

  simple synchronous loading of an audio file (.mp3) in a cocos2d app makes my vmware disconnect the sound. the error is display bottom right, saying 'error in creating sound stream; sound is disconnected' i read that it might be cause of my vmware's version (mine is 8) but I'm looking for a fix, not to downgrade to another version. before i get that error, the sound on the system works just fine (youtube, etc) the exact code im calling is.. [CDSoundEngine setMixerSampleRate: CD_SAMPLE_RATE_MID]; [[CDAudioManager sharedManager] setResignBehavior: kAMRBStopPlay autoHandle:Yes]; soundEngine = [SimpleAudioEngine sharedEngine]; [soundEngine preloadBackgroundMusic:@"somemp3.mp3"]; [soundEngine playBackgroundMusic:@"somemp3.mp3"]; maybe the bit rate is too high .. ? thanks

• Many Associations Leading to Slow Query

  - by Joey Cadle

  I currently have a database that has a lot of many to many associations. I have services which have many variations which have many staff who can perform the variation who then have details on themselves like name, role, etc... At 10 services with 3 variations each and up to 4 out of 20 staff attached to each service even doing something as getting all variations and the staff associated with them takes 4s. Is there a way I can reduce these queries that take a while to process? I've cut down the queries by doing eager loading in my DBM to reduce the problems that arise from 1+N issues, but still 4s is a long query for just a testing stage. Is there a structure out there that would help make such nested many to many associations much quicker to select? Maybe combining everything past the service level into a single table with a 'TYPE' column ?? I'm just not knowledgable enough to know the solution that turns this 4s query into a 300MS query... Any suggestions would be helpful.

• jquery fancy box

  - by André Alçada Padez

  Hi, i'm using fancy box for some content editing in my backoffice. I recently added an image manager wich i create with javascript. It's kind of like a fancybox, but i had to do it from scractch for it to be able to overlay the first one. My problem is this: I want to have the user being able to press the escape key to close my manager, but if i use $(window).keypress when i press the esc key, both the boxes close. I have tried $(window).unbind('keypress') when i start loading my box, and i have tried to look through the fancybox js file, but it is minimized. Does anyone know how i can disable and afterwards enable the escape key (during runtime) on the fancybox? Thanx

• Inheritance - initialization problem

  - by dumbquestion

  I have a c++ class derived from a base class in a framework. The derived class doesn't have any data members because I need it to be freely convertible into a base class and back - the framework is responsible for loading and saving the objects and I can't change it. My derived class just has functions for accessing the data. But there are a couple of places where I need to store some temporary local variables to speed up access to data in the base class. mydata* MyClass::getData() { if ( !m_mydata ) { // set to NULL in the constructor m_mydata = some_long_and complex_operation_to_get_the_data_in_the_base() } return m_mydata; } The problem is if I just access the object by casting the base class pointer returned from the framework to MyClass* the ctor for MyClass is never called and m_mydata is junk. Is there a way of only initializing the m_mydata pointer once?

• Making a jQuery selection in IE on html added via .load()

  - by Joel Crawford-Smith

  Scenario: I am using jQuery to lazy load some html and change the relative href attributes of all the anchors to absolute links. The loading function adds the html in all browsers. The url rewrite function works on the original DOM in all browsers. But In IE7, IE8 I can't run that same function on the new lazy loaded html in the DOM. //lazy load a part of a file $(document).ready(function() { $('#tab1-cont') .load('/web_Content.htm #tab1-cont'); return false; }); //convert relative links to absolute links $("#tab1-cont a[href^=/]").each(function() { var hrefValue = $(this).attr("href"); $(this) .attr("href", "http://www.web.org" + hrefValue) .css('border', 'solid 1px green'); return false; }); I think my question is: whats the trick to getting IE to make selections on DOM that is lazy loaded with jQuery? This is my first post. Be gentle :-) Thanks, Joel

• Load local Html file doesn't refer the js file in UIWebView

  - by Hero Vs Zero

  I am working with UIWebView project and I want to load an HTML file from a project resource. It is working fine when I run from the URL, but when I view the HTML file locally, JS files are not loaded. Loading the local HTML local file doesn't refer to js files in UIWebView. Here's my code to load the HTML file project local resource and does't refer the js file: NSString *path = [[NSBundle mainBundle] pathForResource:@"textfile" ofType:@"txt"]; NSError *error = nil; NSString *string = [[NSString alloc] initWithContentsOfFile:path encoding:NSUTF8StringEncoding error:&error]; NSString *path1 = [[NSBundle mainBundle] bundlePath]; NSURL *baseURL = [NSURL fileURLWithPath:path1]; NSLog(@"%@ >>> %@",baseURL,path); [webview loadHTMLString:string baseURL:baseURL]; This code doesn't find JS files in UIWebView, even though it loads image files from the project resource successfully.

• What is the best way to lazy load doubleclick ads that use document.write?

  - by user560585

  Ads requested through via doubleclick often get served from an ad provider network that returns javascript that in turn performs document.write to place ads in the page. The use of document.write requires that the document be open, implying that the page hasn't reached document.complete. This gets in the way of deferring or lazy loading ad content. Putting such code at page bottom is helpful but doesn't do enough to lower all-important "page-loaded" time. Are "friendly iframes" the best we have? Is there any other alternative such as a clever way to override document.write?

• Using the windows api and C++, how could I load an exe from the hard drive and run it in its own thread?

  - by returneax

  For the sake of learning I'm trying to do what the OS does when launching a program ie. parsing a PE file and giving it a thread of execution. If I have two exe's one called foo.exe and the other bar.exe, how could I have foo.exe load the contents of bar.exe into memory then have it execute from there in its own thread? I know how to get it into memory using MapViewOfFile or by simple loading the contents on the hard drive into a buffer. I'm assuming simply copying the contents of bar.exe on disk into its own suspended thread and running it wouldn't work. I am semi-familiar with PE file internals. All help is very much appreciated, of course :)

• load a word document inside window browser

  - by netNewbi3

  Hi, I have a page that dynamically links to a document that opens in a new page (the document is stored in a database as binary data and I loaded using the following code: Response.ClearContent() Response.ContentType = myReader("MIMEType").ToString() Response.AddHeader("Content-Disposition", "inline; filename=" & myReader("Filename")) Response.BinaryWrite(myReader("DocBD")) Response.End() This works ok. However some documents have restricted access and before loading the document the user is redirected to a login page. After entering username and passowrd the document is loaded. If it is a pdf file for example, it loads in the same login page, but when it is a word or excel document it opens outside the browser window and the login page remains in the background. Is ther a way to force a word or excel document to open inside the browser window? Many thanks.

• Rails 2.3.5 table populated by fixtures at end of test run rather than at start

  - by rlandster

  I start with a test database containing the schema but with no data in the tables. I run a test like so cd test/ ruby unit/directive_test.rb I get failures indicating that the code found no data in the data tables. However, I look at the tables after running that test and the data is now in the the table. In fact, if I immediately run the test again I get no failures. So it appears that the fixture is being loaded into the table too late for one of my modules to find it. When are the fixtures loaded? After or before the app/model/*.rb files are executed? If it is after the models are executed is there a way to delay the loading? This issue is also relevant when running rake test:units since that task clears the test data after it finished.

• Weird landscape UITabBarController Application startup

  - by Stefano Verna

  Hi there. My application is quite simple, but I have some problems when it starts. I setted in the Info.plist to be landscaped, but it seems to ignore the order. In fact, when the app is loading the Simulator is landscaped, but then it returns in portrait mode. This is the hierarchy of the views and controllers: MainViewController (extends UITabBarController just to override shouldAutorotateToInterfaceOrientation:) Three extended UITableViewControllers as tabs (also those have the shouldAutorotateToInterfaceOrientation correctly setted up). If I kinda force the orientation of the device to Landscape with: [[UIDevice currentDevice] setOrientation: UIInterfaceOrientationLandscapeRight]; Then for an instant the Simulator flashes in portrait mode, and then it goes landscaped. The problem is that in this way, the auto-rotation animations gets started, which is something I cannot tollerate. I just want a fixed, landscaped application. Any clues? Am I missing something?

• Collectable<T> serialization, Root Namespaces on T in .xml files.

  - by Stacey

  I have a Repository Class with the following method... public T Single<T>(Predicate<T> expression) { using (var list = (Models.Collectable<T>)System.Xml.Serializer.Deserialize(typeof(Models.Collectable<T>), FileName)) { return list.Find(expression); } } Where Collectable is defined.. [Serializable] public class Collectable<T> : List<T>, IDisposable { public Collectable() { } public void Dispose() { } } And an Item that uses it is defined.. [Serializable] [System.Xml.Serialization.XmlRoot("Titles")] public partial class Titles : Collectable<Title> { } The problem is when I call the method, it expects "Collectable" to be the XmlRoot, but the XmlRoot is "Titles" (all of object Title). I have several classes that are collected in .xml files like this, but it seems pointless to rewrite the basic methods for loading each up when the generic accessors do it - but how can I enforce the proper root name for each file without hard coding methods for each one? The [System.Xml.Serialization.XmlRoot] seems to be ignored.

• Simplest way to extend doctrine for MVC Models

  - by RobertPitt

  Im developing my own framework that uses namespaces. Doctrine is already integrated into my auto loading system and im now at the stage where ill be creating the model system for my application Usually i would create a simple model like so: namespace Application\Models; class Users extends \Framework\Models\Database{} which would inherit all the default database model methods, But with Doctrine im still learning how it all works, as its not just a simple DBAL. I need to understand whats the part of doctrine my classes would extend where i can do the following: namespace Application\Models; class Users Extends Doctrine\Something\Table { public $__table_name = "users"; } And thus within the controller i would be able to do the following: public function Display($uid) { $User = $this->Model->Users->findOne(array("id" => (int)$id)); } Anyone help me get my head around this ?
