• how to access anti aliasing method of a font with CSS

  - by Daniel Ramirez-Escudero

  I've had this problem in a lot of different webs. You have a font which has different anti-aliasing options, the designer uses the same font with different anti-aliasing options on different parts of the text on the web. So there is a difference between some elements. In this case I have sharp, crisp, strong and smooth. I've used a font generator to get the code to access it via @font-face. Even so, I also have the original .otf if important to know. Is there a method to access this? I upload a picture of what I mean and my actual code: ![@font-face { font-family: 'light'; src: url('../_fnt/light/gothamrnd-light.eot'); src: url('../_fnt/light/gothamrnd-light.eot?#iefix') format('embedded-opentype'), url('../_fnt/light/gothamrnd-light.woff') format('woff'), url('../_fnt/light/gothamrnd-light.ttf') format('truetype'), url('../_fnt/light/gothamrnd-light.svg#../_fnt/light/gothamrnd-light') format('svg'); font-weight: normal; font-style: normal; }]![enter image description here][1]

• How should I organize my mvc templates?

  - by CatZ

  Hi, In the new version of MVC we have been given display and editor templates. I was wondering how to make the best possible use of these. I was at first thinking in the line of creating one for a collection and one for an item in the case I want to display either as a list or single but it does not really make sense to me. I'll show you what I mean and please comment if this is wrong. I have trouble figuring it out myself. <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<IEnumerable<DisplayPhoneModel>>" %> <% foreach (var item in Model){%> <%= Html.DisplayFor(x => item) %> <%}%> So in my tiny reality that would for every item in the model search for a display template for DisplayPhoneModel. That display template could then simply look like. <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<DisplayPhoneModel>" %> <%= Html.LabelFor(x => x.PhoneType) %>&nbsp;<%= Html.LabelFor(x => x.PhoneNumber) %> So, question is if there is a better way to handle this? Am I at all on the right path?

• Entity Framework Validation & usage

  - by kmsellers

  I'm aware there is an AssociationChanged event, however, this event fires after the association is made. There is no AssociationChanging event. So, if I want to throw an exception for some validation reason, how do I do this and get back to my original value? Also, I would like to default values for my entity based on information from other entities but do this only when I know the entitiy is instanced for insertion into the database. How do I tell the difference between that and the object getting instanced because it is about to be populated based on existing data? Am I supposed to know? Is that considiered business logic that should be outside of my entity business logic? If that's the case, then should I be designing controller classes to wrap all these entities? My concern is that if I deliver back an entity, I want the client to get access to the properties, but I want to retain tight control over validations on how they are set, defaulted, etc. Every example I've seen references context, which is outside of my enity partial class validation, right? BTW, I looked at the EFPocoAdapter and for the life of me cannot determine how to populate lists of from within my POCO class... anyone know how I get to the context from a EFPoco Class?

• Hide the last children of an XML data provider (not to be displayed in mx:Tree)

  - by Andree

  Hi there! I have an hierachical XML data, and I want to display it as a tree. The XML data is something like this: <services> <service name="TestService" endpoint=""> <method name="sayHi"> <parameter name="firstName" /> <parameter name="lastName" /> </method> <method name="sayGoodbye"> <parameter name="firstName" /> <parameter name="lastName" /> </method> </service> <service name="AnotherTestService"> <method name="getName" /> <method name="setName"> <parameter name="name" /> </method> </service> </services> However, I don't want to display the last elements (parameters) in the tree because, well, it is not meant to be displayed, but still it has to be there. Any advice on how can I achieve that? I am thinking of either extending DefaultDataDescriptor or create a class which implement ITreeDataDescriptor. Which approach will be suitable in this case?

• Downloading Spreadsheets From Google Docs

  - by jeremynealbrown

  Hello, I am working on an Android app that uses the gdata-java-client to download documents for display only. So far I have an application that authenticates with the services and displays a list of user documents. When the user selects a document another query is made for the documents itself. A request for txt, html, rtf and doc files works well, however when I request a spreadsheet in either .csv or .xsl format the result is unexpected. I'm using an HTTPResponse object to store the result of a an HTTPRequest. When I request a document in .csv or .xsl format the HTTPResponse.parseAsString() method produces an entire html page which appears to be the Google Docs home page. Sounds strange, but the result is the actual html for the login page. The HTTPResponse.getStatusMessage returns a 200. Seems like I am missing something simple here. Is there another property of the HTTPResponse that contains the .csv data? I am pretty sure that I am using the correct uri for downloading spreadsheets because it works when I download through my browser. In any case here is an example uri: https://spreadsheets.google.com/feeds/download/spreadsheets/Export?key=0AsE_6_YIr797dHBTUWlHMUFXeTV4ZzJlUGxWRnJXanc&exportFormat=csv Thanks in advance for any help :)

• Generic property- specify the type at runtime

  - by Lirik

  I was reading a question on making a generic property, but I'm a little confused at by the last example from the first answer (I've included the relevant code below): You have to know the type at compile time. If you don't know the type at compile time then you must be storing it in an object, in which case you can add the following property to the Foo class: public object ConvertedValue { get { return Convert.ChangeType(Value, Type); } } That's seems strange: it's converting the value to the specified type, but it's returning it as an object when the value was stored as an object. Doesn't the returned object still require un-boxing? If it does, then why bother with the conversion of the type? I'm also trying to make a generic property whose type will be determined at run time: public class Foo { object Value {get;set;} Type ValType{get;set;} Foo(object value, Type type) { Value = value; ValType = type; } // I need a property that is actually // returned as the specified value type... public object ConvertedValue { get { return Convert.ChangeType(Value, ValType); } } } Is it possible to make a generic property? Does the return property still require unboxing after it's accessed?

• wrapping user controls in a transaction

  - by Hans Gruber

  I'm working on heavily dynamic and configurable CMS system. Therefore, many pages are composed of a dynamically loaded set of user controls. To enable loose coupling between containers (pages) and children (user controls), all user controls are responsible for their own persistence. Each User Control is wired up to its data/service layer dependencies via IoC. They also implement an IPersistable interface, which allows the container .aspx page to issue a Save command to its children without knowledge of the number or exact nature of these user controls. Note: what follows is only pseudo-code: public class MyUserControl : IPersistable, IValidatable { public void Save() { throw new NotImplementedException(); } public bool IsValid() { throw new NotImplementedException(); } } public partial class MyPage { public void btnSave_Click(object sender, EventArgs e) { foreach (IValidatable control in Controls) { if (!control.IsValid) { throw new Exception("error"); } } foreach (IPersistable control in Controls) { if (!control.Save) { throw new Exception("error"); } } } } I'm thinking of using declarative transactions from the System.EnterpriseService namespace to wrap the btnSave_Click in a transaction in case of an exception, but I'm not sure how this might be achieved or any pitfalls to such an approach.

• How can I overlay images over one another in Java?

  - by Sam

  So I have been posting all over and have yet to get a solid answer: I have created an image resizing class, with a crop method. The cropping works great. The issue that I am having is the background color that I specify in the drawImage function of Graphics is not working correctly. It defaults to black as the background regardless of what I supply (in this case Color.WHITE). Also, the overlaying image or top most image (comes from a file) is being inverted (I think it is) or otherwise discolored. Just so you can conceptualize this a little bit better, I am taking a jpeg and overlaying it on top of a new BufferedImage, the new buffered image's background is not being set. Here is the code below that I am working with: public void Crop(int Height, int Width, int SourceX, int SourceY) throws Exception { //output height and width int OutputWidth = this.OutputImage.getWidth(); int OutputHeight = this.OutputImage.getHeight(); //create output streams ByteArrayOutputStream MyByteArrayOutputStream = new ByteArrayOutputStream(); MemoryCacheImageOutputStream MyMemoryCacheImageOutputStream = new MemoryCacheImageOutputStream(MyByteArrayOutputStream); //Create a new BufferedImage BufferedImage NewImage = new BufferedImage(Width, Height, BufferedImage.TYPE_INT_RGB); Graphics MyGraphics = NewImage.createGraphics(); MyGraphics.drawImage(this.OutputImage, -SourceX, -SourceY, OutputWidth, OutputHeight, Color.WHITE, null); // Get Writer and set compression Iterator MyIterator = ImageIO.getImageWritersByFormatName("png"); if (MyIterator.hasNext()) { //get image writer ImageWriter MyImageWriter = (ImageWriter)MyIterator.next(); //get params ImageWriteParam MyImageWriteParam = MyImageWriter.getDefaultWriteParam(); //set outputstream MyImageWriter.setOutput(MyMemoryCacheImageOutputStream); //create new ioimage IIOImage MyIIOImage = new IIOImage(NewImage, null, null); //write new image MyImageWriter.write(null, MyIIOImage, MyImageWriteParam); } //convert output stream back to inputstream ByteArrayInputStream MyByteArrayInputStream = new ByteArrayInputStream(MyByteArrayOutputStream.toByteArray()); MemoryCacheImageInputStream MyMemoryCacheImageInputStream = new MemoryCacheImageInputStream(MyByteArrayInputStream); //resassign as a buffered image this.OutputImage = ImageIO.read(MyMemoryCacheImageInputStream); }

• To implement a remote desktop sharing solution

  - by Cameigons

  Hi, I'm on planning/modeling phase to develop a remote desktop sharing solution, which must be web browser based. In other words: an user will be able to see and interact with someone's remote desktop using his web-browser. Everything the user who wants to share his desktop will need, besides his browser, is installing an add-in, which he's going to be prompted about when necessary. The add-in is required since (afaik) no browser technology allows desktop control from an app running within the browser alone. The add-in installation process must be as simple and transparent as possible to the user (similar to AdobeConnectNow, in case anyone's acquainted with it). The user can share his desktop with lots of people at the same time, but concede desktop control to only one of them at a time(makes no sense being otherwise). Project requirements: All technology employed must be open-source license compatible Both front ends are going to be in flash (browser) Must work on Linux, Windows XP(and later) and MacOSX. Must work at least with IE7(and later) and Firefox3.0(and later). At the very least, once the sharer's stream hits the server from where it'll be broadcast, hereon it must be broadcasted in flv (so I'm thinking whether to do the encoding at the client's machine (the one sharing the desktop) or send it in some other format to the server and encode it there). Performance and scalability are important: It must be able to handle hundreds of dozens of users(one desktop sharer, the rest viewers) We'll definitely be using red5. My doubts concern mostly implementing the desktop publisher side (add-in and streamer): 1) Are you aware of other projects that I could look into for ideas? (I'm aware of bigbluebutton.org and code.google.com/p/openmeetings) 2) Should I base myself on VNC ? 3) Bearing in mind the need to have it working cross-platform, what language should I go with? (My team is very used with java and I have some knowledge of C/C++, but anything goes really). 4) Any other advices are appreciated.

• tabs using jquery

  - by sea_1987

  I currently have a tabbed system in place, however it not doing exactly as I need it too, I was hoping that by navigating to the URL with #tab2 suffixed on then end it would navigate to my tabbed page and the tab that is present in the URL would be the one that is active, however the first tab in the sequence is always active, is there a way to check what is being passed in the URL first and if there is #tabid present then make that tab the current tab? My javascript currently looks like this, $(".tab_content").hide(); //Hide all content $("ul.tabNavigation li.shortlist").addClass("active").show(); //Activate first tab (in this case second because of floats) $(".tab_content#shortlist").show(); //Show first tab content //On Click Event $("ul.tabNavigation li").click(function() { $("ul.tabNavigation li").removeClass("active"); //Remove any "active" class $(this).addClass("active"); //Add "active" class to selected tab $(".tab_content").hide(); //Hide all tab content var activeTab = $(this).find("a").attr("href"); //Find the href attribute value to identify the active tab + content $(activeTab).fadeIn(); //Fade in the active ID content return false; });

• Mmap and structure

  - by blid..pl

  I'm working some code including communication between processes, using semaphores. I made structure like this: typedef struct container { sem_t resource, mutex; int counter; } container; and use in that way (in main app and the same in subordinate processes) container *memory; shm_unlink("MYSHM"); //just in case fd = shm_open("MYSHM", O_RDWR|O_CREAT|O_EXCL, 0); if(fd == -1) { printf("Error"); exit(EXIT_FAILURE); } memory = mmap(NULL, sizeof(container), PROT_READ|PROT_WRITE, MAP_SHARED, fd, 0); ftruncate(fd, sizeof(container)); Everything is fine when I use one of the sem_ functions, but when I try to do something like memory->counter = 5; It doesn't work. Probably I got something wrong with pointers, but I tried almost everything and nothing seems to work. Maybe there's a better way to share variables, structures etc between processes ? Unfortunately I'm not allowed to use boost or something similiar, the code is for educational purposes and I'm intentend to keep as simple as it's possible.

• DataReader already open when using LINQ

  - by Jamie Dixon

  I've got a static class containing a static field which makes reference to a wrapper object of a DataContext. The DataContext is basically generated by Visual Studio when we created a dbml file & contains methods for each of the stored procedures we have in the DB. Our class basically has a bunch of static methods that fire off each of these stored proc methods & then returns an array based on a LINQ query. Example: public static TwoFieldBarData[] GetAgesReportData(string pct) { return DataContext .BreakdownOfUsersByAge(Constants.USER_MEDICAL_PROFILE_KEY, pct) .Select(x => new TwoFieldBarData(x.DisplayName, x.LeftValue, x.RightValue, x.TotalCount)) .ToArray(); } Every now and then, we get the following error: There is already an open DataReader associated with this Command which must be closed firs This is happening intermittently and I'm curious as to what is going on. My guess is that when there's some lag between one method executing and the next one firing, it's locking up the DataContext and throwing the error. Could this be a case for wrapping each of the DataContext LINQ calls in a lock(){} to obtain exclusivity to that type and ensure other requests are queued?

• Improve speed of a JOIN in MySQL

  - by ran2

  Dear all, I know there a similar threads around, but this is really the first time I realize that query speed might affect me - so it´s not that easy for me to really make the transfer from other folks problems. That being said I have using the following query successfully with smaller data, but if I use it on what are mildly large tables (about 120,000 records). I am waiting for hours. INSERT INTO anothertable (id,someint1,someint1,somevarchar1,somevarchar1) SELECT DISTINCT md.id,md.someint1,md.someint1,md.somevarchar1,pd.somevarchar1 from table1 AS md JOIN table2 AS pd ON (md.id = pd.id); Tables 1 and 2 contain about 120,000 records. The query has been running for almost 2 hours right now. Is this normal? Do I just have to wait. I really have no idea, but I am pretty sure that one could do it better since it´s my very first try. I read about indexing, but dont know yet what to index in my case? Thanks for any suggestions - feel free to point my to the very beginners guides ! best matt

• Return value from Object match

  - by Hito_kun

  I'm, by no means, JS fluent, so forgive me if im asking for some really basic stuff, but I've not being able to find a proper answer to my question. Im writting my first Node.js (plus Extra Framework and Socket.io) app and Im having some fun setting up the server side of a FB-like messenger (surprise!!!). So, let's say I have this data structure to store online users(This is a JSON Array, but I'm not sure it is the best way to do it or should I go with Javascript Objects): [ { "site": 45, "users": [ { "idUser": 5, "idSocket": "qwe87r7w8qwe", "name": "Carlos Ray Norris" }, { "idUser": 6, "idSocket": "v8d9d0fgfs7d", "name": "John Connor" } ] }, { "site": 48, "users": [ { "idUser": 22, "idSocket": "qwe87r7w8qwe", "name": "David Bowie" }, { "idUser": 23, "idSocket": "v8d9d0fgfs7d", "name": "Barack H. Obama" } ] } ] What I want to do is to search in the array for x value given y. In this case, retrieving the idSocket knowing the idUser WITHOUT having to run through the array values. So I have basically 2 questions: first, what would be the proper way to store users online? and secondly, how to find values matching with the values I already know (find the idSocket that has a given idUser). I would like a pure JS approach(or using some of the tools given by Node, Socket.io or Express), but if that's not possible then I can look for some JQuery.

• Question about Client IDs

  - by George

  I have a user control that is emmitting javascript using the ClientId function. For example: Out &= "ValidatorHookupControlID(" & Quote & ddlMonth.ClientID & Quote & "), document.all(" & Quote & CustomValidator1.ClientID & Quote & "));" & vbCrLf It appears to me that the ClientID function DOES not return the ultimate ID that is sent to the browser. Instead, the ClientID function only appears to be aware of its current parent control, which in this case is a the User Control and so the ID that is returned is the ID "dtmPassportExpirationDate_ddlMonth" When in fact the usercontrol is included in a master page and the ultimate ID that is used is: "ctl00_phPageContent_dtmPassportExpirationDate_ddlMonth" I may be nuts, but that's what it appears to be doing. I expect that the ClientID function would return the ultimate ID used in the HTML. Am I missing something?

• jQuery event "looping"

  - by Deryck

  Hi I´m trying to code a tooltip (Yes I know, I have my reasons to avoid plugins in this case) in jQuery. Whe I show the tooltip and leave the mouse in the same place the show and hide repeats forever. It´s like the element triggers the hover event again and again and again. I try unbind for the event but it does not work neither. $("td.with-tooltip").mouseover( function() { var offset = $(this).offset(); var baseX = offset.left; var baseY = offset.top; var inputWidth = $(this).width(); var baseX = baseX + 50; var baseY = baseY - $(".desc").height(); $(".desc div").html($(this).attr("title")); $(".desc").css({"position":"absolute", "left": baseX, "top": baseY }).fadeIn(); $(this).unbind("mouseover"); }).mouseleave( function() { $(".desc").fadeOut(); }); What can I do? thanks.

• Ajax Auto Complete in ASP.Net MVC project - How to display a an object's name but actually save it's

  - by Ben

  I have implemented the Ajax Autocomplete feature in my application using a web service file that querys my database and it works great. One problem I am having is allowing the user to see the item's name, as that's what they are typing in the textbox, but when they select it, it saves the item's ID number instead of the actual name. I want it to behave much like a dropdown list, where I can specify what is seen and entered vs. what is actually saved in the database (in this case, the product ID instead of it's name.) I have this text box in my view, along with the script: <script type="text/javascript"> Sys.Application.add_init(function() { $create( AjaxControlToolkit.AutoCompleteBehavior, { serviceMethod: 'ProductSearch', servicePath: '/ProductService.asmx', minimumPrefixLength: 1, completionSetCount: 10 }, null, null, $get('ProductID')) }); </script> <p> <label for="ProductID">Product:</label> <%= Html.TextBox("ProductID", Model.Products)%> <%= Html.ValidationMessage("ProductID", "*")%> </p> Here's what is in my asmx file: public class ProductService : System.Web.Services.WebService { [WebMethod] public string[] ProductSearch(string prefixText, int count) { MyDataContext db = new MyDataContext(); string[] products = (from product in db.Products where product.ProductName.StartsWith(prefixText) select product.ProductName).Take(count).ToArray(); return products; } } Can anyone help me figure this out? I'm using this so they can just start typing instead of having a dropdown list that's a mile long...

• Jquery Cycle in Drupal - onAfter effect not working.

  Im using the views slideshow module for drupal which uses the jquery cycle plugin. Here is my first simple slideshow where everything works properly: smartpeopletalkfast.co.uk/slideshow3/one Here is my 2nd slideshow: smartpeopletalkfast.co.uk/slideshow3/two Im trying to use the onAfter function. I want the next and previous buttons to be hidden when at the end of their cycle. This is demonstrated here: jquery.malsup.com/cycle/after.html The first slideshow that's working has these controls: prev: #prev1, next: #next1 The 2nd slideshow has these: prev: #prev1, next: #next1, end: onAfterr, timeout: 0 And Ive added this to the beginning of my document head. <script type="text/javascript"> function onAfterr(curr, next, opts) { var index = opts.currSlide; $('#prev1')[index == 0 ? 'hide' : 'show'](); $('#next1')[index == opts.slideCount - 1 ? 'hide' : 'show'](); } </script> I changed onAfter to onAfterr in case of a conflict. Nothing ive tried works and ive no idea why!

• Algorithm for count-down timer that can add on time

  - by Person

  I'm making a general timer that has functionality to count up from 0 or count down from a certain number. I also want it to allow the user to add and subtract time. Everything is simple to implement except for the case in which the timer is counting down from some number, and the user adds or subtracts time from it. For example: (m_clock is an instance of SFML's Clock) float Timer::GetElapsedTime() { if ( m_forward ) { m_elapsedTime += m_clock.GetElapsedTime() - m_elapsedTime; } else { m_elapsedTime -= m_elapsedTime - m_startingTime + m_clock.GetElapsedTime(); } return m_elapsedTime; } To be a bit more clear, imagine that the timer starts at 100 counting down. After 10 seconds, the above function would look like 100 -= 100 - 100 + 10 which equals 90. If it was called after 20 more seconds it would look like 90 -= 90 - 100 + 30 which equals 70. This works for normal counting, but if the user calls AddTime() ( just m_elapsedTime += arg ) then the algorithm for backwards counting fails miserably. I know that I can do this using more members and keeping track of previous times, etc. but I'm wondering whether I'm missing some implementation that is extremely obvious. I'd prefer to keep it as simple as possible in that single operation.

• How to get application context path in spring-ws?

  - by Dhaliwal

  I am using Spring-WS to create a webservice. In my project, I have created a Helper class to reads sample response and request xml file which are located in my /src/main/resource folder. When I am unit-testing my webservice application 'locally', I use the System.getProperty("user.dir") to get the application context folder. The following is a method that I created in the Helper class to help me retrieve the file that I am interested in my resource folder. public static File getFileFromResources(String filename) { System.out.println("Getting file from resource folder"); File request = null; String curDir = System.getProperty("user.dir"); String contextpath = "C:\\src\\main\\resources\\"; request = new File(curDir + contextpath + filename); return request; } However, after 'publishing' the compiled WAR file to the ../webapps folder to the Apache Tomcat directory, I realise that System.getProperty("user.dir") no longer returns my application context path. Instead, it is returning the Apache Tomcat root directory as shown C:\Program Files\Apache Software Foundation\Tomcat 6.0\src\main\resources\SampleClientFile I cant seem to find any information about getting the root folder of my webservice. I have seen examples on Spring web application where I can retrieve the context path by using the following : request.getSession().getServletContext().getContextPath() But in this case, I am using a Spring web application where there is a servlet context in the request. But the Spring-WS, my entry point is an endpoint. How can I get the context path of my webservice application. I am expecting a context path of something like C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\clientWebService\WEB-INF\classes Could someone suggest a way to achieve this?

• How to store data in mysql, to get the fastest performance?

  - by Oden

  Hey, I'm thinking about it, witch of the following two query types would give me the fastest performance for a user messaging module inside my site: The first one i thought about is a multi table setup, witch has a connection table, and a main table. The connection table holds the connection between accounts, and the messaging table. In this case a query would look like following, to get some data of the author, and the messages he has sent: SELECT m.*, a.username FROM messages AS m LEFT JOIN connection_table ON (message_id = m.id) LEFT JOIN accounts AS a ON (account_id = a.id) WHERE m.id = '32341' Inserting into it is a little bit more "complicated". My other idea, and in my thought the better solution of this problem is that i store the data i would use in a connection table in the same table where is store the data of the mail. Sounds like i would get lots of duplicated entries, but no, because i have a field witch has text type and holds user ids like this: *24*32*249* If I want to query them, i use the mysql LIKE method. Deleting is an other problem, but for this i have one more field where i store who has deleted the post. Sad about that i don't know how to join this. So what would you recommend? Are there other ways?

• PHP: What is an efficient way to parse a text file containing very long lines?

  - by Shaun

  I'm working on a parser in php which is designed to extract MySQL records out of a text file. A particular line might begin with a string corresponding to which table the records (rows) need to be inserted into, followed by the records themselves. The records are delimited by a backslash and the fields (columns) are separated by commas. For the sake of simplicity, let's assume that we have a table representing people in our database, with fields being First Name, Last Name, and Occupation. Thus, one line of the file might be as follows [People] = "\Han,Solo,Smuggler\Luke,Skywalker,Jedi..." Where the ellipses (...) could be additional people. One straightforward approach might be to use fgets() to extract a line from the file, and use preg_match() to extract the table name, records, and fields from that line. However, let's suppose that we have an awful lot of Star Wars characters to track. So many, in fact, that this line ends up being 200,000+ characters/bytes long. In such a case, taking the above approach to extract the database information seems a bit inefficient. You have to first read hundreds of thousands of characters into memory, then read back over those same characters to find regex matches. Is there a way, similar to the Java String next(String pattern) method of the Scanner class constructed using a file, that allows you to match patterns in-line while scanning through the file? The idea is that you don't have to scan through the same text twice (to read it from the file into a string, and then to match patterns) or store the text redundantly in memory (in both the file line string and the matched patterns). Would this even yield a significant increase in performance? It's hard to tell exactly what PHP or Java are doing behind the scenes.

• Help with accessing a pre-existing window AFTER opener is refreshed!

  Alright, I'm at my wit's end on this issue. First, backstory. I'm working on a video management system where we're allowing users, when adding new content, to upload and, optionally, transcode a media file. We're using Java applet for the browser-based FTP client. What I want to do is allow a user to initiate an upload and then send the FTP connection instance to a popup window. This window will act as a job queue for the FTP transfer process. This will allow users to move about the main interface without having to stay on the original page until an individual file transfer is complete. For the most part I have all of this working, but here's a problem. If the window is closed, all connections are dropped and the upload process for all queued files will be canceled. So, if Window One opens the Popup Window, adds stuff to the queue, refreshes the screen or moves to a different page, how will I access the Popup Window? The popup window and its contents must remain persistent while the user navigates through the original window. The original window must be able to access the popup to add a new job to the queue. The popup window itself is independent of the opening window, so communication only happens in one direction: Parent - Popup Not Parent <- Popup Window.open(null, 'WINDOW_NAME'); will not work in this case. I need to check if a window exists BEFORE using window.open. Help!?!?

• Adroid's DateFormat replacement - missing the format() with FieldPosition

  - by user331244

  Hi, I need to split a date string into pieces and I'm doing it using the public final StringBuffer format (Object object, StringBuffer buffer, FieldPosition field) from the java.text.DateFormat class. However, the implementation of this function is really slow, hence Android has an own implementation in android.text.format.DateFormat. BUT, in my case, I want to extract the different pieces of the date string (year, minute and so on). Since I need to be locale independent, I can not use SimpleDateFormat and custom strings. I do it as follows: Calendar c = ... // find out what field to extract int field = getField(); // Create a date string Field calendarField = DateFormat.Field.ofCalendarField(field); FieldPosition fieldPosition = new FieldPosition(calendarField); StringBuffer label = new StringBuffer(); label = getDateFormat().format(c.getTime(), label, fieldPosition); // Find the piece that we are looking for int beginIndex = fieldPosition.getBeginIndex(); int endIndex = fieldPosition.getEndIndex(); String asString = label.substring(beginIndex, endIndex); For some reason, the format() overload with the FieldPosition argument is not included in the android platform. Any ideas of how to do this in another way? Is there any easy way to tokenize the pattern string? Any other ideas?
