• sIFR3: controlling a and a:hover styles inside replaced through CSS rather than JS

  - by sneeuwitje

  For graceful degrading and minimal coding for the sIFR feature on my websites I would want to define styles in CSS as much as possible. Here's what I do: Define a H3 tag to be replaced by sIFR3. H3 comes in varying colors by CSS depending on it's container, say body.blue-txt h3{ color: #009CDA; } body.white-txt h3{ color: #FFFFFF; } body.etc... H3 might contain an anchor (I'm aware of semantical issues, but that's just how it is ... sorry) With setting sIFR.useStyleCheck = true; sIFR3 will show replaced normal H3 text with correct color, but when it contains a link, it shows the Flash default #0000FF .... All fine; I can tweak e.g. blue text in sifr-config.js by using the css-parameter for sIFR.replace(): sIFR.replace(futura, { selector: 'body.blue-txt h3', css: 'a {color: #009CDA; }, a:hover { color: #009CDA; text-decoration: underline; }' }); But that would have to be coded for every single text-color in my sIFR replacements in both JS and CSS. So I would want to make the sIFR.useStyleCheck setting just respect the CSS in sifr-config.css like: body.blue-txt h3{ color: #009CDA; } body.blue-txt h3 a{ color: #009CDA; } body.blue-txt h3 a:hover{ color: #009CDA; text-decoration: underline; } Only this doesn't seem to work ... the link text keeps popping up as #0000FF and the hover is not underlined. Is this just Not A Feature (Yet), or am doing something wrong?

• Problems playing multiple sounds using AVPlayer (NOT AVAudioPlayer)

  - by myetter37

  I'm trying to play a background song in my iPhone game and also have sound effects, using the AVFoundation framework and AVPlayerItem. I've scoured the Internet for help with AVPlayerItem and AVPlayer but I'm only finding stuff about AVAudioPlayer. The background song plays fine, but when the character jumps, I have 2 problems: 1) On the initial jump ([player play] inside jump method), the jump sound effect interrupts the background music. 2) If I try to jump again, the game crashes with the error "AVPlayerItem cannot be associated with more than one instance of AVPlayer" My professor told me to create a new instance of AVPlayer for each sound I want to play, so I'm confused. I'm doing data driven design, so my sound files are listed in a .txt and then loaded into a NSDictionary. Here's my code: - (void) storeSoundNamed:(NSString *) soundName withFileName:(NSString *) soundFileName { NSURL *assetURL = [[NSURL alloc] initFileURLWithPath:[[NSBundle mainBundle] pathForResource:soundName ofType:soundFileName]]; AVURLAsset *mAsset = [[AVURLAsset alloc] initWithURL:assetURL options:nil]; AVPlayerItem *mPlayerItem = [AVPlayerItem playerItemWithAsset:mAsset]; [soundDictionary setObject:mPlayerItem forKey:soundName]; NSLog(@"Sound added."); } - (void) playSound:(NSString *) soundName { // from .h: @property AVPlayer *mPlayer; // from .m: @synthesize mPlayer = _mPlayer; _mPlayer = [[AVPlayer alloc] initWithPlayerItem:[soundDictionary valueForKey:soundName]]; [_mPlayer play]; NSLog(@"Playing sound."); } If I move this line from the second method into the first: _mPlayer = [[AVPlayer alloc] initWithPlayerItem:[soundDictionary valueForKey:soundName]]; The game does not crash, and the background song will play perfectly, but the jump sound effect does not play, even though the console is showing "Playing sound." on each jump. Thank you

• Having Uploadify e-mail a link to download the file

  - by kwek-kwek

  Uploadify is a jQuery plugin that allows the easy integration of a multiple (or single) file uploads on your website. It requires Flash and any backend development language. An array of options allow for full customization for advanced users, but basic implementation is so easy that even coding novices can do it. I wanted to ask if It is possible to sends out a link of a file that has just been uploaded wioth the e-mail notification of Uploadify. Here is the code for uploadify.php : <?php if (!empty($_FILES)) { $tempFile = $_FILES['Filedata']['tmp_name']; $targetPath = $_SERVER['DOCUMENT_ROOT'] . $_REQUEST['folder'] . '/'; $targetFile = str_replace('//','/',$targetPath) . $_FILES['Filedata']['name']; // $fileTypes = str_replace('*.','',$_REQUEST['fileext']); // $fileTypes = str_replace(';','|',$fileTypes); // $typesArray = split('\|',$fileTypes); // $fileParts = pathinfo($_FILES['Filedata']['name']); // if (in_array($fileParts['extension'],$typesArray)) { // Uncomment the following line if you want to make the directory if it doesn't exist // mkdir(str_replace('//','/',$targetPath), 0755, true); move_uploaded_file($tempFile,$targetFile); echo "1"; // } else { // echo 'Invalid file type.'; // } } //define the receiver of the email $to = '[email protected]'; //define the subject of the email $subject = 'Test email'; //define the message to be sent. Each line should be separated with \n $message = "Hello World!\n\nThis is my first mail."; //define the headers we want passed. Note that they are separated with \r\n $headers = "From: [email protected]\r\nReply-To: [email protected]"; //send the email $mail_sent = @mail( $to, $subject, $message, $headers ); //if the message is sent successfully print "Mail sent". Otherwise print "Mail failed" echo $mail_sent ? "Mail sent" : "Mail failed"; ?>

• Trigger for ComboBox in Silverlight

  - by Budda

  Is there any possibility to display selected item of the ComboBox (after popup closing) in a way that is different from its displaying in DropDown List (There are players number and name in the dropdown list, but after list closing I want to see only its number). How can I change a background for the player with some Flag? As far as I know, all of that can be done with triggers, but are they supported in Silverlight 4, VS2010, Silverlight Toolkit 4? In my case the following code <ComboBox ItemsSource="{Binding PlayersAll}" SelectedItem="{Binding Path=SelectedPlayer, Mode=TwoWay}" > <ComboBox.ItemTemplate> <DataTemplate> <ToolkitControls:WrapPanel Orientation="Horizontal"> <TextBlock Text="{Binding TeamNumber}"/> <TextBlock Text=" - "/> <TextBlock Text="{Binding ShortName}"/> </ToolkitControls:WrapPanel> <DataTemplate.Triggers> <Trigger Property="HasError" Value="True"> <Setter Property="Background" TargetName="FlagSet" Value="Red"/> </Trigger> </DataTemplate.Triggers> </DataTemplate> </ComboBox.ItemTemplate> </ComboBox> gives an error: The property 'Triggers' does not exist on the type 'DataTemplate' in the XML namespace 'http://schemas.microsoft.com/winfx/2006/xaml/presentation' what is wrong here? Here are my namespaces: xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:navigation="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Navigation" xmlns:data="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Data" xmlns:ToolkitControls="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Toolkit"

• Wysiwyg with image copy/paste

  - by jW

  First, I understand that an image cannot be "copied" from a local machine into a website. I understand that it must be uploaded. I am a web programmer, and am familiar with common web wysiwyg tools such as TinyMCE and FCKEditor. My question is if there exists a program or web module or something of the sort that works will perform an automatic upload of images for a wysiwyg. I have a client that is constantly complaining about not being able to copy/paste documents with images from MS Word into a wysiwyg to create content on their website. I have looked into TX Text Control (http://labs.textcontrol.com/) and was looking into a possibly flash wysiwyg that could upload the file automatically behind the scenes. I don't know if this exists, and google did not much help me in my search, so I thought I would ask other coders. I am open to any sort of server technology, or browser requirements. I am looking for some browser based tool instead of an application tool such as Dreamweaver or otherwise. If no good solution to the problem exists, I am willing to accept that at this point. Note: This was a request from a client, and to me it seemed rather unreasonable. I decided to gather community advice instead of just tell the client 'No' and the options here have been extremely helpful and informative in presenting possible solutions.

• PHP CURL Google Calendar using Private URL

  - by MooCow

  I'm trying to get an array of events from Google Calendar using the Private URL. I read the Google API document but I want to try doing this without using the ZEND library since I have no idea what the eventual server file structure is and avoid having other people edit the codes. I also did a search before posting and ran into the same condition where PHP CURL_EXEC returns false with the URL but I get a JSON file if the URL is open using a web browser. Since I'm using the Private URL, do I really need to authenticate against the Google server using ZEND? I'm trying to have PHP clean up the array before encoding it for Flash. $URL = <string of the private URL from Google Calendar> $ch = curl_init($URL); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); $data = curl_exec($ch); curl_close($ch); $result = json_decode($data); print '<pre>'.var_export($data,1).'</pre>'; Screen output >>> false

• Programmer Puzzle: Encoding a chess board state throughout a game

  - by Andrew Rollings

  Not strictly a question, more of a puzzle... Over the years, I've been involved in a few technical interviews of new employees. Other than asking the standard "do you know X technology" questions, I've also tried to get a feel for how they approach problems. Typically, I'd send them the question by email the day before the interview, and expect them to come up with a solution by the following day. Often the results would be quite interesting - wrong, but interesting - and the person would still get my recommendation if they could explain why they took a particular approach. So I thought I'd throw one of my questions out there for the Stack Overflow audience. Question: What is the most space-efficient way you can think of to encode the state of a chess game (or subset thereof)? That is, given a chess board with the pieces arranged legally, encode both this initial state and all subsequent legal moves taken by the players in the game. No code required for the answer, just a description of the algorithm you would use. EDIT: As one of the posters has pointed out, I didn't consider the time interval between moves. Feel free to account for that too as an optional extra :) EDIT2: Just for additional clarification... Remember, the encoder/decoder is rule-aware. The only things that really need to be stored are the player's choices - anything else can be assumed to be known by the encoder/decoder. EDIT3: It's going to be difficult to pick a winner here :) Lots of great answers!

• what is the best way to stream a audio file to website users/listners

  - by Naveen Chamikara Gamage

  I'm developing a music site which will stream audio files stored in a server to users, audio files will be played through flash player placed in a webpage.. As I heard I need to use a streaming media server for streaming audio files ( like 2mb to 3mb in size).. Do I need to use one? I found some streaming media server softwares like http://www.icecast.org - but as in their documentation, It is used for streaming radio stations and live streaming purposes, but I just need to stream audio files faster and in low size (low bandwidth) with good quality.. I heard I need to encode the audio files first and then send them to listeners and in their end audio files need to be decoded again. Is that true? How can I do that? if I need to use a special web server, where should I host my files? Any good hosting providers? if I host audio files in a normal web server, they will use HTTP or TCP to deliver my audio files to users/ listners but I found that HTTP and TCP are not good ways to use for multi media purposes like streaming audio and video files, and they are used for delivering HTML and stuff. I found I should use RSTP or UDP for streaming audio files.. What should I use? I know that .MP3 files has much better quality than the other formats but it also gives huge size to the audio files.. which format should I use for audio files? Most of the best quality audio files are more than 7mb so I'm planning to convert them my self using a software so I could get low size files with some level of good quality. If I'm converting my audio files what is the good BITRATE I should use for my files? Any known best softwares for converting audio files while keeping quality in a good level? Note** - I know that I will not need complex requirements at the beginning of the site but I wanted to what are the best ways like they are using for soundcloud.com

• Google Maps Api android key

  Hi, I have some trouble testing my Android application which includes the google maps API. The ooficial API example worked just fine but if I copy the code into my own project it keeps saying: "The application has stopped unexpectedly".

• Rich faces and dataTable

  - by ortho

  Hi all :) I have the question regarding rich faces and beans. I have a jsp page that is using richfaces and inside it I have the: rich:extendedDatatable component, that takes data from my MainBean as ArrayList (this bean queries the mySQL and puts results to the ArrayList that populates the dataTable later on). There are 4 columns in datatable, first 3 are h:outputLabels and the last one is checkbox. Now I have a question: how can I get information from selected row ? I mean, when user clicks checkbox, I want to take the id/name or whatever that is associated to this particular row, then when user clicks on Apply changed a4j: button I will update the database and when user logs in back again he will see updated info: e.g. checkbox is selected/not selected now because the user checked that. I believe that is a simple query for someone who worked with it. For me ex. flash developer it would be easy in as3, but here I didnt find the solution yet, please help. Thank you in advance, Kindest regards

• Abstract Base Class or Class?

  - by Mohit Deshpande

  For my semester project, my team and I are supposed to make a .jar file (library, not runnable) that contains a game development framework and demonstrate the concepts of OOP. Its supposed to be a FRAMEWORK and another team is supposed to use our framework and vice-versa. So I want to know how we should start. We thought of several approaches: 1. Start with a plain class public class Enemy { public Enemy(int x, int y, int health, int attack, ...) { ... } ... } public class UserDefinedClass extends Enemy { ... } 2. Start with an abstract class that user-defined enemies have to inherit abstract members public abstract class Enemy { public Enemy(int x, int y, int health, int attack, ...) { ... } public abstract void draw(); public abstract void destroy(); ... } public class UserDefinedClass extends Enemy { ... public void draw() { ... } public void destroy() { ... } } 3. Create a super ABC (Abstract Base Class) that ALL inherit from public abstract class VectorEntity { ... } public abstract class Enemy extends VectorEntity { ... } public class Player extends VectorEntity { ... } public class UserDefinedClass extends Enemy { ... } Which should I use? Or is there a better way?

• glitchy stuttery iphone game loop

  - by Adam

  This is a problem I've been trying to solve for a few days now, and I've looked at the various solutions on stackoverflow and nothing has really seemed to work for me. I'm making an iPhone game with OpenGLES graphics and accelerometer input, at this point it's very simple, but the rendering is already pretty bad... it stutters and seems to jump back or forward in time. It doesn't happen a lot, but it happens enough to be a problem. I mean, who wants to play a game where a bullet gets magically transported into the player, and then it's game over? No one. I've tried using NSTimer for the game loop, I've tried using a separate thread (with a frame rate and continuously) I've tried using different frame rates, from 30FPS to 60FPS (It seems to have a max frame rate around 45FPS, but no problems at 30FPS) I've tried using timeIntervalSince1970 and CFGetAbsoluteTime to measure loop time, with no noticeable diffence Anyone have any ideas on what is the best way to get this looking better? One of the posts I've read suggested running the simulation at a fixed frame rate and then just render as fast as possible, does that seem like a good idea?

• searching article for names in the database before submitting article to the database

  - by zurna

  I want to create a function that will search through a text, find names those match with existing names in the database and add links to those names before submitting the article to the database. i.e. text: Chelsea are making a change now as goalscorer Nicolas Anelka is replaced by in-form Florent Malouda who can do no wrong lately. Nicolas Anelka exists in the database in the Players table with ID column equals to 1. I want text to be converted to Chelsea are making a change now as goalscorer a href="player.asp=ID=1"Nicolas Anelka/a is replaced by in-form Florent Malouda who can do no wrong lately. I know my code is logically wrong but I could build the correct logic. Function PlayerStats (ArticleDesc) If IsNull(ArticleDesc) Then Exit Function SQL = "SELECT PlayerID, PlayerName" SQL = SQL & " FROM Players" ' SQL = SQL & " WHERE PlayerID = "& &"" Set objPlayer = objConn.Execute(SQL) Do While NOT objPlayer.EOF ArticleDesc = Replace(ArticleDesc, objPlayer("PlayerName"), "!"&objPlayer("PlayerName")&"!") PlayerStats = ArticleDesc Loop objPlayer.MoveNext End Function

• Flex: How to resize DisplayObject to fit panel in Flex application

  - by ohm

  I am trying to attach some of my actionscript class, inherited from Sprite, to my Flex application by attaching it to a UIComponent, then add UIComponent to a panel. However, the size of my Sprite class appears to be larger than the panel. So, I try to resize it using DisplayObject.scale property, but I need to know the size of my container. Since I try to make my code reusable, I figure that I should let my Sprite class handle the resize by getting it via its parent property (let's say, I can resize it by set this.scaleX = this.parent.Width/this.width or something like this) However, my Sprite class's parent, which is the UIComponent, has width/height of 0. So, my question is: 1) Is there any better way to resize DisplayObject class to fit its container when attached to Flex object? 2) If you know, why my UIComponent's size remain 0 and my DisplayObject still appears at its full size? Here's my code, using Flash Builder 4: private var loader:Loader = new Loader(); private function testLoader():void { var urlRequest:URLRequest = new URLRequest("http://localhost/welcome.png"); loader.load(urlRequest); loader.contentLoaderInfo.addEventListener(Event.COMPLETE,onLoaderLoadComplete); } private function onLoaderLoadComplete(e:Event):void { loader.contentLoaderInfo.removeEventListener(Event.COMPLETE,onLoaderLoadComplete); var ui : UIComponent = new UIComponent(); ui.addChild(loader); panelTest.addElement(ui); trace("ui.width = " + ui.width); trace("ui.height = " + ui.height); trace("loader.width = " + loader.width); trace("loader.height = " + loader.height); trace("panelTest.width = " + panelTest.width); trace("panelTest.height = " + panelTest.height); } And this is the result when run: ui.width = 0 ui.height = 0 loader.width = 571 loader.height = 411 panelTest.width = 480 panelTest.height = 320

• Modularity in Flex

  - by Fernando

  I'm working on a pretty big application for Flex/Air. We are using GraniteDS and Tide to interact with the model from our Java EE server. I've been reading about modularization and Modules in Flex. The application has already been built, and I'm figuring a way out to re-design some classes and parts. From what I've read so far, I understand a Module is a different swf which can be dynamically load. Most of the tutorials/documentation are oriented to Flash "programmers" who are using Flex or Air instead of real developers, so that makes online resources harder to get. What I can't understand - yet - is how to encapsulate ActionScript classes or MXML views under this module. I've separated some of the code into libraries. For example, the generated code from Granite is in a "server" library. But I would like to separate parts of the logic with its Moderators, Controllers and Views. Are modules the way to go? Is there a "modules for dummies" or "head first Flex Modules for programmers" like tutorial in order to get a better perspective in order to build my architecture? When to choose libraries and when to choose modules? I'm using Flex 3.5, and a migration to Flex 4 is way far into the future, so no Flex 4 answers please, thanks!

• What is best strategy to handle exceptions & errors in Rails?

  - by Nick Gorbikoff

  Hello. I was wondering if people would share their best practices / strategies on handling exceptions & errors. Now I'm not asking when to throw an exception ( it has been throroughly answered here: SO: When to throw and Exception) . And I'm not using this for my application flow - but there are legitimate exceptions that happen all the time. For example the most popular one would be ActiveRecordNotFound. What would be the best way to handle it? The DRY way? Right now I'm doing a lot of checking within my controller so if Post.find(5) returns Nil - I check for that and throw a flash message. However while this is very granular - it's a bit cumbersome in a sense that I need to check for exceptions like that in every controller, while most of them are essentially the same and have to do with record not found or related records not found - such as either Post.find(5) not found or if you are trying to display comments related to post that doesn't exist, that would throw an exception (something like Post.find(5).comments[0].created_at) I know you can do something like this in ApplicationController and overwrite it later in a particular controller/method to get more granular support, however would that be a proper way to do it? class ApplicationController < ActionController::Base rescue_from ActiveRecord::RecordInvalid do |exception| render :action => (exception.record.new_record? ? :new : :edit) end end

  - by eugeneK

  Hi, i have this error on one of my sites. Searched thought all project found no Dictionary of some kind.

• Prefix for element not bound

  - by Tim

  Hello! I am a newbie in Flex development and using Flash Builder 4 with SDK 4. Now I get the error that "the prefix "fx" for element "fx:Style" is not bound" in line number 4. I searched for it, and it has sth. to do with namespaces, but I can not solve it by myelf. I have the file called "UserStory.mxml" in the directory "components" to place it via the main.mxml onto the screen: <fx:Script> <![CDATA[ import components.UserStory; private function init():void { var userStory1:UserStory = new UserStory(); userStory1.x = 100; userStory1.y = 100; userStory1.userStoryText = "test"; this.addChild(userStory1); } ]]> </fx:Script> The file in which the error occurs in line no. 4: <?xml version="1.0" encoding="utf-8"?> <mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml" width="300" height="150" styleName="userstory"> <fx:Style source="styles/styles.css"/> <fx:Text x="5" y="5" width="275" height="135" text="{userStoryText}" fontFamily="notes" fontSize="18"/> <mx:Script> ... </mx:Script> </mx:Canvas> Can someone tell me what's wrong? Thanks a lot in advance & Best Regards.

• HttpHandler and XML files

  - by Frank

  Hello, I would like to intercept any request made to the server for XML files. I thought that it might be possible with an HttpHandler. It's coded and it works... on localhost only (?!?!). So, why is it working on localhost only? Here is my web.config <?xml version="1.0" encoding="utf-8"?> <configuration> <system.web> <httpHandlers> <add verb="*" path="*.xml" type="FooBar.XmlHandler, FooBar" /> </httpHandlers> </system.web> </configuration> Here is my C# : namespace FooBar { public class XmlHandler : IHttpHandler { public bool IsReusable { get { return false; } } public void ProcessRequest(HttpContext context) { HttpResponse Response = context.Response; Response.Write(xmlString); } } } As you might have seen, I'm writing the xmlString directly in the response, it's only temporary because I'm still wondering how I could give the filename instead (that's the second question ;) ) What is supposed to be written in the response is only the xml filename that will be retrieved by a flash app. Thanks Edit : When calling the page from another computer it looks like it's not getting to the HttpHandler. However, the mapping for IIS have been done correctly.

• Dynamic Google Maps API InfoWindow HTML Content

  - by Peter Hanneman

  I am working in Flash Builder 4 with Google Map's ActionScript API. I have created a map, loaded some custom markers onto it and added some MouseEvent listeners to each marker. The trouble comes when I load an InfoWindow panel. I want to dynamically set the htmlContent based off of information stored in a database. The trouble is that this information can change every couple of seconds and each marker has a unique data set so I can not statically set it at the time I actually create the markers. I have a method that will every minute or so load all of the records from my database into an Object variable. Everything I need to display in the htmlContent is contained in this object under a unique identifier. The basic crux of the problem is that there is no way for me to uniquely identify an info window, so I can not determine what information to pull into the panel. marker.addEventListener(MapMouseEvent.ROLL_OVER, function(e:MapMouseEvent):void { showInfoWindow(e.latLng) }, false, 0, false); That is my mouse event listener. The function I call, "showInfowindow" looks like this: private function showInfoWindow(latlng:LatLng):void { var options:InfoWindowOptions = new InfoWindowOptions({title: appData[*I NEED A UNIQUE ID HERE!!!*].type + " Summary", contentHTML: appData[*I NEED A UNIQUE ID HERE!!!*].info}); this.map.openInfoWindow(latlng, options); } I thought I was onto something by being able to pass a variable in my event listener declaration, but it simply hates having a dynamic variable passed through, it only returns the last value use. Example: marker.addEventListener(MapMouseEvent.ROLL_OVER, function(e:MapMouseEvent):void { showInfoWindow(e.latLng, record.unit_id) }, false, 0, false); That solution is painfully close to working. I iterate through a loop to create my markers when I try the above solution and roll over a marker I get information, but every marker's information reflects whatever information the last marker created had. I apologize for the long explaination but I just wanted to make my question as clear as possible. Does anyone have any ideas about how to patch up my almost-there-solution that I posted at the bottom or any from the ground up solutions? Thanks in advance, Peter Hanneman

• video streaming over http in blackberry

  - by ysnky

  hi all, while i was searching video player over http, i found the article which is located at this url; http://www.blackberry.com/knowledgecenterpublic/livelink.exe/fetch/2000/348583/800332/1089414/Stream ing_media_-_Start_to_finish.html?nodeid=2456737&ve rnum=0 i can run by adding ";deviceside=true" at the end of url. it works fine in the jde4.5 simulator. it gets 3gp videos from my local server. i tested with 580kb files and works fine. but when i get the same file from my server (not local, real server) i have problems with big files (e.g 580 kb). it plays 180kb files (but sometimes it does not play this file either) but not plays 580kb file. and also i deployed my application to my 9000 device it sometimes plays small file (180kb) but never plays big file (580kb). why it plays if it is on my local file, not play in real world? i ve stucked for days. hope you help me. and also the code at the url given below is not work, the only code i ve found is the above. blackberry.com/knowledgecenterpublic/livelink.exe/fetch/2000/348583/800332/1089414/How_To _-_Play_video_within_a_BlackBerry_smartphone_appli cation.html?nodeid=1383173&vernum=0 btw, there is no method such as resize(long param) of CircularByteBuffer class. so i comment relavent line (buffer.resize(buffer.getSize() + (buffer.getSize() * percent / 100)); as shown below. public void increaseBufferCapacity(int percent) { if(percent < 0){ log(0, "FAILED! SP.setBufferCapacity() - " + percent); throw new IllegalArgumentException("Increase factor must be positive.."); } synchronized(readLock){ synchronized(connectionLock){ synchronized(userSeekLock){ synchronized(mediaIStream){ log(0, "SP.setBufferCapacity() - " + percent); //buffer.resize(buffer.getSize() + (buffer.getSize() * percent / 100)); this.bufferCapacity = buffer.getSize(); } } } } } thanks in advance.

• SoundManager / Jquery : Get SoundID sID

  - by j-man86

  So I am trying to access a jquery soundmanager variable from one script (wpaudio.js – from the wp-audio plugin) inside of another (init.js – my own javascript). I am creating an alternate pause/play button higher up on the page and need to resume the current soundID, which is contained as part of a class name in the DOM. Here is the code that creates that class name in wpaudio.js: function wpaButtonCheck() { if (!this.playState || this.paused) jQuery('#' + this.sID + '_play').attr('src', wpa_url + '/wpa_play.png'); else jQuery('#' + this.sID + '_play').attr('src', wpa_url + '/wpa_pause.png'); } Here is the output: <img src="http://24.232.185.173/wordpress/wp-content/plugins/wpaudio-mp3-player/wpa_play.png" class="wpa_play" id="wpa0_play"> where wpa0 would be the sID of the sound I need. My current script in init.js is: $('.mixesSidebar #currentSong .playBtn').toggle(function() { soundManager.pauseAll(); $(this).addClass('paused'); }, function() { soundManager.resumeAll(); $(this).removeClass('paused'); }); I need to change resumeAll to "resume(this.sID)", but I need to somehow store the sID onclick and call it in the above function. Alternately, I think a regular expression that could get the class name of the current play button and either parse the string up to the "_play" or use a trim function to get rid of "_play"– but I'm not sure how to do this. Thanks for your help!

• XNA 2D mouse picking

  - by Corndog

  I'm working on a simple 2D Real time strategy game using XNA. Right now I have reached the point where I need to be able to click on the sprite for a unit or building and be able to reference the object associated with that sprite. From the research I have done over the last three days I have found many references on how to do "Mouse picking" in 3D which does not seem to apply to my situation. I understand that another way to do this is to simply have an array of all "selectable" objects in the world and when the player clicks on a sprite it checks the mouse location against the locations of all the objects in the array. the problem I have with this approach is that it would become rather slow if the number of units and buildings grows to larger numbers. (it also does not seem very elegant) so what are some other ways I could do this. (Please note that I have also worked over the ideas of using a Hash table to associate the object with the sprite location, and using a 2 dimensional array where each location in the array represents one pixel in the world. once again they seem like rather clunky ways of doing things.)
