  • What's wrong with debugging in Eclipse on Android?

    - by Sebastian Dwornik
    I've obviously been spoiled by Visual Studio, because although I'm just learning Android and the Eclipse environment, debugging apps in Eclipse is becoming a serious detriment to further development. For example, Eclipse will compile this divide by zero just fine: public class Lesson2Main extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate (savedInstanceState); int i = 1 / 0; TextView tv = new TextView (this); tv.setText ("Hello, Android!"); setContentView (tv); } } And then, when it executes it under the debugger, I will get a full screen of useless debug info, non of which actually points me to the specific line containing the error. The stackTrace is null within the exception ('e') info tree, and it simply states a message stating 'ArithmeticException'. (that's nice, how about you point me in the direction of where you found it!?) I've looked all over the screen and am baffled that this IDE can't get this right. Does developing with Eclipse resort everyone back to 1991 with printf() like logging at every interval then to track down bugs? Seriously. Is there a configuration or plug-in that I'm missing to help with this? I haven't tested this case with XCode, but if the iPhone dev. IDE handles this more like Visual Studio, then no wonder the Android marketplace has so few apps. I'm excited about Android, but it seems that Eclipse is getting in the way.

  • Deploying a Java application. How?

    - by danpalmer
    I am new to Java (and Eclipse) but I have used .NET (and Visual Studio) a fair amount. I also know about compiling C/C++ code and things like that. I know that at the end I get either an EXE or a nice binary file that can be run from the command line. I have been making a Java utility that uses some external libraries. I need to compile this into an executable that I can run from the command line on a unix machine, but I cannot find any way to do this. I can build and run/debug in Eclipse, but that is no use to me as this code will be run on a webserver. I just need all the dependancies compiled in to one file but after hours of searching on Google, the best thing I could find was the Fat-JAR plugin for Eclipse and after using that I just get the following error when I try to run the file: Exception in thread "main" java.lang.NoClassDefFoundError: Network/jar This is really confusing me and as it is such an essential thing to be able to do I am sure I must be missing something blindingly obvious, but as I said, after hours of searching I have gotten nowhere. I really appreciate any help you can give me. Thanks.

  • How to handle dates that repeat indefinitely

    - by Addsy
    I am implementing a fairly simple calendar on a website using PHP and MySQL. I want to be able to handle dates that repeat indefinitely and am not sure of the best way to do it. For a time limited repeating event it seems to make sense to just add each event within the timeframe into my db table and group them with some form of recursion id. But when there is no limit to how often the event repeats, is it better to a) put records in the db for a specific time frame (eg the next 2 years) and then periodically check and add new records as time goes by - The problem with this is that if someone is looking 3 years ahead, the event won't show up b) not actually have records for each event but instead when i check in my php code for events within a specified time period, calculate wether a repeated event will occur within this time period - The problem with this is that it means there isn't a specific record for each event which i can see being a pain when i then want to associate other info (attendance etc) with that event. It also seems like it might be a bit slow Has anyone tried either of these methods? If so how did it work out? Or is there some other ingenious crafty method i'm missing?

  • If Then Else Statement Condition Being Ignored?

    - by Matma
    I think im going mad but can some show me what im missing, it must be some stupidly simple i just cant see the wood for the trees. BOTH side of this if then else statement are being executed? Ive tried commenting out the true side and moving the condition to a seperate variable with the same result. However if i explicitly set the condition to 1=0 or 1=1 then the if then statement is operating as i would expect. i.e. only executing one side of the equation... The only time ive seen this sort of thing is when the compiler has crashed and is no longer compiling (without visible indication that its not) but ive restarted studio with the same results, ive cleaned the solution, built and rebuilt with no change? please show me the stupid mistake im making using vs2005 if it matters. Dim dset As DataSet = New DataSet If (CboCustomers.SelectedValue IsNot Nothing) AndAlso (CboCustomers.SelectedValue <> "") Then Dim Sql As String = "Select sal.SalesOrderNo As SalesOrder,cus.CustomerName,has.SerialNo, convert(varchar,sal.Dateofpurchase,103) as Date from [dbo].[Customer_Table] as cus " & _ " inner join [dbo].[Hasp_table] as has on has.CustomerID=cus.CustomerTag " & _ " inner join [dbo].[salesorder_table] as sal On sal.Hasp_ID =has.Hasp_ID Where cus.CustomerTag = '" & CboCustomers.SelectedValue.ToString & "'" Dim dap As SqlDataAdapter = New SqlDataAdapter(Sql, FormConnection) dap.Fill(dset, "dbo.Customer_Table") DGCustomer.DataSource = dset.Tables("dbo.Customer_Table") Else Dim erm As String = "wtf" End If

  • Register and Resolve Generic Interfaces Unity

    - by user1643791
    I am trying to register some generic interfaces and resolve them . I have the registering function private static void RegisterFolderAssemblies(Type t,string folder) { var scanner = new FolderGenericInterfaceScanner(); var scanned = scanner.Scan(t,folder); // gets the implementations from a specific folder scanned.ForEach(concrete => { if (concrete.BaseType != null || concrete.IsGenericType) { myContainer.RegisterType(t, Type.GetType(concrete.AssemblyQualifiedName), concrete.AssemblyQualifiedName); } }); } which is called by the bootstrapper with RegisterFolderAssemblies(typeof(IConfigurationVerification<>),Environment.CurrentDirectory); The registration seem to go through ok but when I try to Resolve them with Type generic = typeof(IConfigurationVerification<>); Type specific = generic.MakeGenericType(input.Arguments[0].GetType()); var verifications = BootStrap.ResolveAll(specific); The input.Arguments[0] is an object of the type the generic is implemented in I also tried using typeof(IConfigurationVerification<) instead and get the same error . When ResolveAll is public static List<object> ResolveAll(Type t) { return myContainer.ResolveAll(t).ToList(); } I get a ResolutionFailedException with them message "The current type, Infrastructure.Interfaces.IConfigurationVerification`1[Infrastructure.Configuration.IMLogPlayerConfiguration+LoadDefinitions], is an interface and cannot be constructed. Are you missing a type mapping?" Any help will be great. Thanks in advance

  • Help on understanding multiple columns on an index?

    - by Xaisoft
    Assume I have a table called "table" and I have 3 columns, a, b, and c. What does it mean to have a non-clustered index on columns a,b? Is a nonclustered index on columns a,b the same as a nonclustered index on columns b,a? (Note the order). Also, Is a nonclustered index on column a the same as a nonclustered index on a,c? I was looking at the website sqlserver performance and they had these dmv scripts where it would tell you if you had overlapping indexes and I believe it was saying that having an index on a is the same as a,b, so it is redundant. Is this true about indexes? One last question is why is the clustered index put on the primary key. Most of the time the primary key is not queried against, so shouldn't the clustered index be on the most queried column. I am probably missing something here like having it on the primary key speeds up joins? Great explanations. Should I turn this into a wiki and change the title index explanation?

  • How should a one-man development shop document their code?

    - by CKoenig
    Hi, please let me first describe my situation. I work in an IT department for a small-to-medium sized industrial-company and basically I'm the only real developer (sometimes a second guy joins in for his own projects). I programm mostly in C#/.net. Of course I only programm for internal need (Intranet, reporting, data-driven apps, some mobile apps, ...). My question is how should I document my work? It's a highly dynamic environment (the features and bug fixes I implement are tested by me during production, and go live, often within a day. If I technical documentation like MSDN or even overview diagramms those would take me more time to sync than the whole programming process. Also I feel it's a waste of time because I would be the only one who ever read it. I do understand that if I get sick, leave, or forget this documentation would be valuable. PS:well of course you are right - the quesion is how much and how/where. I try using the XML-docu comments for the public exposed parts but as I'm a believer in self-documenting code the comments mostly restates in plain text what you can read from the method-head itself :(Maybe using the remarks section is the key but if you have 30 lines of code with a 15 line xml-comment in front it just looks dirty (sorry for posting it here but our firewall rejects JSON :( )

  • Recognize Dates In A String

    - by Tim Scott
    I want a class something like this: public interface IDateRecognizer { DateTime[] Recognize(string s); } The dates might exist anywhere in the string and might be any format. For now, I could limit to U.S. culture formats. The dates would not be delimited in any way. They might have arbitrary amounts of whitespace between parts of the date. The ideas I have are: ANTLR Regex Hand rolled I have never used ANTLR, so I would be learning from scratch. I wonder if there are libraries or code samples out there that do something similar that could jump start me. Is ANTLR too heavy for such a narrow use? I have used Regex a lot before, but I hate it for all the reasons that most people hate it. I could certainly hand roll it but I'd rather not re-solve a solved problem. Suggestions? UPDATE: Here is an example. Given this input: This is a date 11/3/63. Here is another one: November 03, 1963; and another one Nov 03, 63 and some more (11/03/1963). The dates could be in any U.S. format. They might have dashes like 11-2-1963 or weird extra whitespace inside like this: Nov   3,   1963, and even maybe the comma is missing like [Nov 3 63] but that's an edge case. The output should be an array of seven DateTimes. Each date would be the same: 11/03/1963 00:00:00.

  • Which language should I use to program a GUI application?

    - by Roman
    I would like to write a GUI application for management of information (text documents). In more details, it should be similar to the TiddlyWiki. I would like to have there some good visual effects (like nice representation for three structures, which you can rotate, some sound). I also would like to include some communication via Internet (for sharing and collaboration). In should include some features of such applications as a web browser, word processor, Skype. Which programming language should I use? I like the idea of usage of JavaScripts (like TddlyWiki). The good thing about that, is that user should not install anything. They open a file in a browser and it works! The bad thing is that JavaScript cannot communicate via internet with other applications. I think the choice of the programming language, in my case, id conditioned by 2 things: What can be done with this programming language (which restrictions are there). How easy to program. I would like to have "block" which can do a lot of things (rather than to program then and, in this way, to "rediscover a bicycle") ADDED: I would like to make it platform independent.

  • How to restart a wcf server from within a client?

    - by djerry
    Hey guys, I'm using Wcf for server - client communication. The server will need to run as a service, so there's no GUI. The admin can change settings using the client program and for those changes to be made on server, it needs to restart. This is my server setup NetTcpBinding binding = new NetTcpBinding(SecurityMode.Message); Uri address = new Uri("net.tcp://localhost:8000"); //_svc = new ServiceHost(typeof(MonitoringSystemService), address); _monSysService = new MonitoringSystemService(); _svc = new ServiceHost(_monSysService, address); publishMetaData(_svc, "http://localhost:8001"); _svc.AddServiceEndpoint(typeof(IMonitoringSystemService), binding, "Monitoring Server"); _svc.Open(); MonitoringSystemService is a class i'm using to handle client - server comm. It looks like this: [CallbackBehavior(ConcurrencyMode = ConcurrencyMode.Reentrant)] [ServiceBehavior(InstanceContextMode = InstanceContextMode.Single, MaxItemsInObjectGraph = 2147483647)] public class MonitoringSystemService : IMonitoringSystemService {} So i need to call a restart method on the client to the server, but i don't know how to restart (even stop - start) the server. I hope i'm not missing any vital information. Thanks in advance.

  • jQuery loading issues within wordpress

    - by Chase
    I am having a couple problems trying to manually insert some jQuery features into a wordpress theme. I have a lightbox wordpress plugin that is jQuery based that is working fine. So if I manually load the jQuery script into wordpress the functions seem to work but instead of say a slide being hidden it is revealed when it should still be hidden. Or a pop up that should work is already being shown instead of hidden. I don't think I'm supposed to manually include the jQuery into my skin but using the wp_enqueue_script('jquery'); doesn't seem to be resolving my issues either. <script src="http://platform.twitter.com/anywhere.js?id=i5CnpkmwnlWpDdAZGVpxw&v=1" type="text/javascript"></script> <script type="text/javascript"> $(document).ready(function(){ $(".btn-slide").click(function(){ $("#twitpanel").slideToggle("slow"); $(this).toggleClass("active"); }); }); </script> <div id="tweetit"><a class="btn-slide">Tell em'</a> <div id="twitpanel"></div> <script type="text/javascript"> twttr.anywhere(function (T) { T("#twitpanel").tweetBox({ height: 100, width: 225, defaultContent: "Some Random Text" }); }); </script> </div></h2> Like I said it works but in the reverse fashion that it should be. I think I'm just loading in something wrong? TIA, Chase

  • Applying for .net jobs as a "self learner"

    - by DeanMc
    Hi All, I have recently started applying for .Net jobs. I currently work in a sales role with a large telco. I found out quite late that I like programming and as such bought my house and made commitments that mean college is not an option. What I would like to know is, is it harder to get a junior job as a self learner? I have gotten a few enquiries regarding my C.V but nothing concrete yet. I try to be involved in projects as I get the chance and tend to put up any worthwhile projects as I develop them. Some examples of my work are: A Xaml lexer and parser: http://www.xlight.mendhak.com A font obfuscation tool: http://www.silverlightforums.com/showthread.php?1516-Font-Obsfucation-Tool-ALPHA A tagger for m4a: http://projectaudiophile.codeplex.com/SourceControl/list/changesets I, of course think that these are great examples of my work but that is my opinion based on self learning. The other query is how much should I actually know? I've never used linked lists but I know that strings are immutable and I understand what that means. I am only touching on T-SQL but I understand things like how properties function in IL (as two standard methods :) ). I suppose I understand a lot of concepts but specific features need some looking up to implement as I may not know the syntax off the top of my head.

  • Putting a C++ Vector as a Member in a Class that Uses a Memory Pool

    - by Deep-B
    Hey, I've been writing a multi-threaded DLL for database access using ADO/ODBC for use with a legacy application. I need to keep multiple database connections for each thread, so I've put the ADO objects for each connection in an object and thinking of keeping an array of them inside a custom threadInfo object. Obviously a vector would serve better here - I need to delete/rearrange objects on the go and a vector would simplify that. Problem is, I'm allocating a heap for each thread to avoid heap contention and stuff and allocating all my memory from there. So my question is: how do I make the vector allocate from the thread-specific heap? (Or would it know internally to allocate memory from the same heap as its wrapper class - sounds unlikely, but I'm not a C++ guy) I've googled a bit and it looks like I might need to write an allocator or something - which looks like so much of work I don't want. Is there any other way? I've heard vector uses placement-new for all its stuff inside, so can overloading operator new be worked into it? My scant knowledge of the insides of C++ doesn't help, seeing as I'm mainly a C programmer (even that - relatively). It's very possible I'm missing something elementary somewhere. If nothing easier comes up - I might just go and do the array thing, but hopefully it won't come to that. I'm using MS-VC++ 6.0 (hey, it's rude to laugh! :-P ). Any/all help will be much appreciated.

  • Geolocation and jQuery - Can't post results using ajax

    - by etombaugh
    I'm currently working on a project to make a location-aware site. In essence, the user comes to the page, and their location is found using the HTML5 method and then using jQuery, the location is posted to a page which saves the location/address to a codeigniter session, but if they want to update their location, or change to a different location(IE they want to use their work address as the location instead of their present address), theres a jQuery colorbox that displays and lets them type in a custom address. Everything works flawlessly to get the initial location, but when I try and get the updated location saved, I receive the error "Uncaught TypeError: Object [object DOMWindow] has no method 'lat'" which then Google Chrome references as being an error not in jQuery, but in the file for Google Maps API. Any suggestions? jQuery('.inputsubmit').click(function() { //Takes values from user submitted fields and parses them into an address string var street = jQuery('.inputaddress').val(); var city = jQuery('.inputcity').val(); var state = jQuery('.inputstate').val(); var address = street +" "+ city +", " +state; geocoder = new google.maps.Geocoder(); var geocoderresult= geocoder.geocode({'address': address}, function(results, status) { if (status == google.maps.GeocoderStatus.OK) { var newlocation = results[0].geometry.location; //Posts coordinates and address string to a CodeIgniter function to update users session information jQuery.post("somepage", {location: newlocation, address: address},function(data) { alert("Data Loaded: " + data); }); } else { alert("Geocoder failed due to: " + status); } }); }); I've tried everything I can think of to get the post to work. All of the code works up till the point, and I've commented out the post line and everything works correctly. This is one of our main website's features, to provide instant and quick results based off of location. Thanks!

  • Really simple JSON serialization in .NET

    - by Evgeny
    I have some simple .NET objects I'd like to serialize to JSON and back again. The set of objects to be serialized is quite small and I control the implementation, so I don't need a generic solution that will work for everything. Since my assembly will be distributed as a library I'd really like to avoid a dependency on some third-party DLL: I just want to give users one assembly that they can reference. I've read the other questions I could find on converting to and from JSON in .NET. The recommended solution of JSON.NET does work, of course, but it requires distributing an extra DLL. I don't need any of the fancy features of JSON.NET. I just need to handle a simple object (or even dictionary) that contains strings, integers, DateTimes and arrays of strings and bytes. On deserializing I'm happy to get back a dictionary - it doesn't need to create the object again. Is there some really simple code out there that I could compile into my assembly to do this simple job? I've also tried System.Web.Script.Serialization.JavaScriptSerializer, but where it falls down is the byte array: I want to base64-encode it and even registering a converter doesn't let me easily accomplish that due to the way that API works (it doesn't pass in the name of the field).

  • Gradle fails injecting dependencies into subprojects using fileTree

    - by Matthias
    Maybe I'm missing something about the way Gradle works. What I have here is a parent project, which only contains configuration, i.e. there won't be any artifact being built when building it, it merely manages and builds all its subprojects. Now the subprojects share some dependency configuration, so I figured what I would do in the root project's build.gradle is: subprojects { dependencies { compile fileTree(dir: 'lib', includes: ['*.jar']) } } that, however, does not work, it fails with a rather obscure error message: A problem occurred evaluating root project 'qype-android' Cause: No signature of method: org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.compile() is applicable for argument types: (org.gradle.api.internal.file.DefaultConfigurableFileTree) values: [file set 'lib'] Possible solutions: module(java.lang.Object) after some trial and error, I could "fix" this issue by applying the 'java' plugin to the parent project. How come? I don't see anywhere from the Gradle docs that a fileTree dependency requires the Java plugin. Even so, why would I need it on the project that is injecting the configuration, as opposed to on the project that is being configured (note that the subprojects all apply the Java plugin themselves)? Does this mean that if I have N different subprojects that are all of varying natures, and apply different plugins, that the parent projects must always apply the set of all plugins beings used somewhere to itself, too?

  • unistd.h related problem when compiling bison & flex program under vc++

    I'm using bison & flex (downloaded via cygwin) with vc++. When I compile the program I got an error: ...: fatal error C1083: Cannot open include file: 'unistd.h': No such file or directory The corresponding code in the flex-generated file is: #ifndef YY_NO_UNISTD_H /* Special case for "unistd.h", since it is non-ANSI.

  • What guidelines should be followed when using an unstable/testing/stable branching scheme?

    - by Elliot
    My team is currently using feature branches while doing development. For each user story in our sprint, we create a branch and work it in isolation. Hence, according to Martin Fowler, we practice Continuous Building, not Continuous Integration. I am interested in promoting an unstable/testing/stable scheme, similar to that of Debian, so that code is promoted from unstable = testing = stable. Our definition of done, I'd recommend, is when unit tests pass (TDD always), minimal documentation is complete, automated functional tests pass, and feature has been demo'd and accepted by PO. Once accepted by the PO, the story will be merged into the testing branch. Our test developers spend most of their time in this branch banging on the software and continuously running our automated tests. This scares me, however, because commits from another incomplete story may now make it into the testing branch. Perhaps I'm missing something because this seems like an undesired consequence. So, if moving to a code promotion strategy to solve our problems with feature branches, what strategy/guidelines do you recommend? Thanks.

  • Existing LINQ extension method similar to Parallel.For?

    - by Joel Martinez
    The linq extension methods for ienumerable are very handy ... but not that useful if all you want to do is apply some computation to each item in the enumeration without returning anything. So I was wondering if perhaps I was just missing the right method, or if it truly doesn't exist as I'd rather use a built-in version if it's available ... but I haven't found one :-) I could have sworn there was a .ForEach method somewhere, but I have yet to find it. In the meantime, I did write my own version in case it's useful for anyone else: using System.Collections; using System.Collections.Generic; public delegate void Function<T>(T item); public delegate void Function(object item); public static class EnumerableExtensions { public static void For(this IEnumerable enumerable, Function func) { foreach (object item in enumerable) { func(item); } } public static void For<T>(this IEnumerable<T> enumerable, Function<T> func) { foreach (T item in enumerable) { func(item); } } } usage is: myEnumerable.For<MyClass>(delegate(MyClass item) { item.Count++; });

  • How can I filter a Perl DBIx recordset with 2 conditions on the same column?

    - by BrianH
    I'm getting my feet wet in DBIx::Class - loving it so far. One problem I am running into is that I want to query records, filtering out records that aren't in a certain date range. It took me a while to find out how to do a "<=" type of match instead of an equality match: my $start_criteria = ">= $start_date"; my $end_criteria = "<= $end_date"; my $result = $schema->resultset('MyTable')->search( { 'status_date' => \$start_criteria, 'status_date' => \$end_criteria, }); The obvious problem with this is that since the filters are in a hash, I am overwriting the value for "status_date", and am only searching where the status_date <= $end_date. The SQL that gets executed is: SELECT me.* from MyTable me where status_date <= '9999-12-31' I've searched CPAN, Google and SO and haven't been able to figure out how to apply 2 conditions to the same column. All documentation I've been able to find shows how to filter on more than 1 column, but not 2 conditions on the same column. I'm sure I'm missing something obvious - hoping someone here can point it out to me? Thanks in advance! Brian

  • How to install Eclipse + PHP Development Tools (PDT) + Debugger on Mac in The Year 2010

    - by aphex5
    I had a lot of trouble installing Eclipse and PDT on my system. It took two days, largely because all the tutorials I could find were out of date (written in 2008, it's 2010 now) and various steps they included were no longer necessary, broken, or irrelevant. I wanted to write my process here so it could be improved upon (via wiki) as time goes on. Install Eclipse without PHP plugin ("Eclipse Classic"). This will give you a complete Eclipse, which I find preferable, as the UI is more fleshed out (e.g. you get a default list of Perspectives, which helps you understand what Perspectives are.) Install PDT SDK with the Help Install New Software menu item. You'd think you'd be done here, but if you try to run something, it'll fail complaining of not having a debugger. Install the Zend Debugger. It'll fail if you try to use the Install New Software option, as many tutorials suggest ("No repository found containing osgi.bundle.org.zend.php.debug.debugger.5.3.7.v20091116".) Instead, download it from http://www.zend.com/en/community/pdt, and manually copy the features/ and plugins/ directory into your Eclipse install (these instructions are not written anywhere). Restart Eclipse Monkey with preferences for a while -- if you followed a previous tutorial and tried to manually add your php executable to Eclipse prefs (/usr/bin/php), remove it (PHP PHP Executables). Set one of the Zend Debugger executables to the default. If you've already tried to execute a .php file, remove the existing "Run" profile you (maybe weren't aware that you) created (Run Debug Configurations...). Eclipse works! You should be able to run a .php file as a script just fine.

  • Comet, responseText and memory usage

    - by ithcy
    Is there a way to clear out the responseText of an XHR object without destroying the XHR object? I need to keep a persistent connection open to a web server to feed live data to a browser. The problem is, there is a relatively large amount of data coming through (several hundred K per second constantly), so memory usage is a big problem, because this connection must remain open for at least several minutes. responseText gets very big very quickly, even though the JSON I send back has been crunched as small as it can get. Due to the way the server-side app works, if I use AJAX-style short polling and just destroy the XHR object when I'm done with it, I miss significant amounts of important data even in the few milliseconds it takes to parse the response, create a new XHR and send it out. I do not have the option to use overlapping requests, as the web server only accepts one connection at a time. (Don't ask.) So Comet is exactly the model I need. What I would like to do is parse each JSON chunk as it comes back from the server, and then clear out responseText so that I can keep using the same connection. However, responseText is read-only. It cannot be directly emptied by any method I have found. Is there a part of the picture I am missing here? Does anyone know any tricks I can use to free up responseText when I'm done reading it? Or is there another place the server responses can go? I am not including code because this is really almost a code-agnostic question. The Javascript routines that spawn the XHRs and handle the returned data are very, very simple.

  • Javascript Object.Watch for all browsers?

    - by SeanW
    Hey all, I was looking for an easy way to monitor an object or variable for changes, and I found Object.Watch that's supported in Mozilla browsers, but not IE. So I started searching around to see if anyone had written some sort of equivalent. About the only thing I've found has been a jQuery plugin (http://plugins.jquery.com/files/jquery-watch.js.txt), but I'm not sure if that's the best way to go. I certainly use jQuery in most of my projects, so I'm not worried about the jQuery aspect... Anyway, the question: can someone show me a working example of that jQuery plugin? I'm having problems making it work... Or, does anyone know of any better alternatives that would work cross browser? Thanks! Update after answers: Thanks everyone for the responses! I tried out the code posted here: http://webreflection.blogspot.com/2009/01/internet-explorer-object-watch.html But I couldn't seem to make it work with IE. The code below works fine in FireFox, but does nothing in IE. In Firefox, each time watcher.status is changed, the document.write in watcher.watch is called and you can see the output on the page. In IE, that doesn't happen, but I can see that watcher.status is updating the value, because the last document.write shows the correct value (in both IE and FF). But, if the callback function isn't called, then that's kind of pointless... :) Am I missing something? var options = {'status': 'no status'}, watcher = createWatcher(options); watcher.watch("status", function(prop, oldValue, newValue) { document.write("old: " + oldValue + ", new: " + newValue + "<br>"); return newValue; }); watcher.status = 'asdf'; watcher.status = '1234'; document.write(watcher.status + "<br>");

  • jQuery XML loading and then innerfade effect

    - by Ryan Max
    Hello, I think I can explain myself without code, so for brevity's sake here we go: I am using jquery to pull data from an xml and put it into a ul on the page with each xml entry as a li. This is working great! However, what I am trying to do afterwards is use the innerfade plugin to make a simple animation between each of the li's. It's not working though, as it is still just loading the static list with each item visible (whereas if innerfade was working it would only display the first....then fade into the second, etc) It's not an innerfade problem however, because if I add the list in manually to the page (not injecting it with jquery) then the innerfade works fine. I'm relatively new to DOM scripting, so I think I am missing something here. I'm not quite sure how jQuery sequences everything, and I'm having trouble phrasing my question in a search engine friendly manner so here I am. Is it possible to have jquery pull the data from xml, then inject it into the page, then have innerfade work it's magic? Or am I thinking about this the wrong way? xml code: $.ajax({ type: "GET", url: "xml/playlist.xml", dataType: "xml", success: function(xml) { $(xml).find('song').each(function(){ var name = $(this).attr('title'); var date = $(this).attr('artist'); var message = $(this).attr('path'); $('<li></li>').html('<span id="an_name">'+name+'</span><span id="an_date">'+date+'</span><span id="an_message">'+message+'</span>').appendTo('#anniversary'); }); } }); innerfade code: <script type="text/javascript"> jQuery.noConflict(); jQuery(document).ready( function(){ jQuery('#anniversary').innerfade({ speed: 1000, timeout: 5000, type: 'sequence', }); });

  • How to Use XSLT to Replace Coordinate Separator With List of Tuples?

    - by kuloch
    I have a space-separated list of coordinate tuples. Each tuple consists of a space-separated list of 2-dimensional coordinates. E.g. "1.1 2.8 1.2 2.9" represents a line from POINT(1.1 2.8) to POINT(1.2 2.9). I need this to instead be "1.1,2.8 1.2,2.9". How would I use XSLT to perform the replacement of space-to-comma between pairs of numbers? I have the "string(gml:LinearRing/gml:posList)". This is being used on a Java Web Service that spits out GML 3.1.1 features with geometries. The service supports optional KML output, by using XSLT to transform the GML document into a KML document (at least, the chunks deemed "important"). I am locked into XSLT 1.0, so regex from XSLT 2.0 is not an option. I am aware that GML uses lat/lon while KML uses lon/lat. That's being handled before XSLT, though it would be nice to have that also done with XSLT.
