• Framework or tool for "distributed unit testing"?

  - by user262646

  Is there any tool or framework able to make it easier to test distributed software written in Java? My system under test is a peer-to-peer software, and I'd like to perform testing using something like PNUnit, but with Java instead of .Net. The system under test is a framework I'm developing to build P2P applications. It uses JXTA as a lower subsystem, trying to hide some complexities of it. It's currently an academic project, so I'm pursuing simplicity at this moment. In my test, I want to demonstrate that a peer (running in its own process, possibly with multiple threads) can discover another one (running in another process or even another machine) and that they can exchange a few messages. I'm not using mocks nor stubs because I need to see both sides working simultaneously. I realize that some kind of coordination mechanism is needed, and PNUnit seems to be able to do that. I've bumped into some initiatives like Pisces, which "aims to provide a distributed testing environment that extends JUnit, giving the developer/tester an ability to run remote JUnits and create complex test suites that are composed of several remote JUnit tests running in parallel or serially", but this project and a few others I have found seem to be long dead.

• ASP.NET or PHP: Is Memcached useful for storing user-state information?

  - by hamlin11

  This question may expose my ignorance as a web developer, but that wouldn't exactly be a bad thing for me now would it? I have the need to store user-state information. Examples of information that I need to store per user. (define user: unauthenticated visitor) User arrived to the site from google/bing/yahoo User utilized the search feature (true/false) List of previous visited product pages on current visit It is my understanding that I could store this in the view state, but that causes a problem with page load from the end-users' perspective because a significant amount of non-viewable information is being transferred to and from the end-users even though the server is the only side that needs the info. On a similar note, it is my understanding that the session state can be used to store such information, but does not this also result in the same information being transferred to the user and stored in their cookie? (Not quite as bad as viewstate, but it does not feel ideal). This leaves me with either a server-only-session storage system or a mem-caching solution. Is memcached the only good option here?

• Cross-Origin Resource Sharing (CORS) - am I missing something here?

  - by David Semeria

  I was reading about CORS (https://developer.mozilla.org/en/HTTP_access_control) and I think the implementation is both simple and effective. However, unless I'm missing something, I think there's a big part missing from the spec. As I understand, it's the foreign site that decides, based on the origin of the request (and optionally including credentials), whether to allow access to its resources. This is fine. But what if malicious code on the page wants to POST a user's sensitive information to a foreign site? The foreign site is obviously going to authenticate the request. Hence, again if I'm not missing something, CORS actually makes it easier to steal sensitive information. I think it would have made much more sense if the original site could also supply an immutable list of servers its page is allowed to access. So the expanded sequence would be: 1) Supply a page with list of acceptable CORS servers (abc.com, xyz.com, etc) 2) Page wants to make an XHR request to abc.com - the browser allows this because it's in the allowed list and authentication proceeds as normal 3) Page wants to make an XHR request to malicious.com - request rejected locally (ie by the browser) because the server is not in the list. I know that malicious code could still use JSONP to do its dirty work, but I would have thought that a complete implementation of CORS would imply the closing of the script tag multi-site loophole. I also checked out the official CORS spec (http://www.w3.org/TR/cors) and could not find any mention of this issue.

• Benefits of "Don't Fragment" on TCP Packets?

  - by taspeotis

  One of our customers is having trouble submitting data from our application (on their PC) to a server (different geographical location). When sending packets under 1100 bytes everything works fine, but above this we see TCP retransmitting the packet every few seconds and getting no response. The packets we are using for testing are about 1400 bytes (but less than 1472). I can send an ICMP ping to www.google.com that is 1472 bytes and get a response (so it's not their router/first few hops). I found that our application sets the DF flag for these packets, and I believe a router along the way to the server has an MTU less than/equal to 1100 and dropping the packet. This affects 1 client in 5000, but since everybody's routes will be different this is expected. The data is a SOAP envelope and we expect a SOAP response back. I can't justify WHY we do it, the code to do this was written by a previous developer. So... Are there are benefits OR justification to setting the DF flag on TCP packets for application data? I can think of reasons it is needed for network diagnostics applications but not in our situation (we want the data to get to the endpoint, fragmented or not). One of our sysadmins said that it might have something to do with us using SSL, but as far as I know SSL is like a stream and regardless of fragmentation, as long as the stream is rebuilt at the end, there's no problem. If there's no good justification I will be changing the behaviour of our application. Thanks in advance.

• Organising files and classes in XCode (iPhone application)

  - by pulegium

  It's a generic question and really a newbie one too, so bear with me... I'm playing with some iPhone development, and trying to create a simple "flip type" application. Nothing sophisticated, let's say on the flip side is a short application summary, bit like 'help' and on the main screen is a simple board game, let's say tic-tac-toe or similar. Now, XCode has generated me 'Main View', 'Flipside View' and 'Application Delegate' folders, with default template files in them. Now the question is where do I create appropriate 'MVC' classes? Let's say (V)iew classes are going to be the ones that have been automatically created. So the Flipside view class is responsible for generating text/images etc on the 'help' view. 'Main View' class is what draws the items on the table and updates the counters, etc. Where should I place the 'controller' class? And also, should it only be dealing with proxying only to the model? According to this the controller method is called from the view and manipulates the method classes. Similarly, the results from model are passed back to the view class by the controller issuing the calls to appropriate view methods. Similarly, where does the model class go? or should I just create a new folder for each, controller and model class files? What I'm after is the best practices, or just a short description how people normally structure their applications. I know it's very specific and also undefined... I came from Django background, so the way stuff is organised there is slightly different. Hope this makes sense, sorry if it's all bit vague, but I have to start somewhere :) And yes I've read quite few docs on the apple developer site, but trouble is that the documents are either going into too much detail about the language/framework/etc and the examples are way too simplistic. Actually, this leads me to the final question, has anyone know any good example of relatively complete application tutorial which I could use as a reference in organising my files?...

• How can I automatically highlight a specific character in link text using JQuery + CSS?

  - by Chris McCall

  I'm adding hotkeys to a web application in order to enable keyboard shortcuts for our CSRs to use, to reduce injury and increase calls-per-hour. I'm using an ASP.net UserControl to inject javascript into the page and it's working great. I want the control to "just work", so that when hotkeys are assigned, using a declarative syntax, if the hotkeyed letter exists in the link text, it will be highlighted automatically, so the developer doesn't have to do anything, and also to maintain consistency in visual cues. Here's the code to assign hotkeys, if it matters: <uc:HotKeysControl ID="theHotkeys" runat="server" Visible="true"> <uc:HotKey ControlName="AccStatus$btnInvoiceEverBill" KeyCode="ctrl+v" /> <uc:HotKey ControlName="AccStatus$btnRefund" KeyCode="ctrl+u" /> <uc:HotKey ControlName="thirdControl" KeyCode="ctrl+p" /> </uc:HotKeysControl> I want something like: <a href="whatever" name="thirdControl">Make a <span class=hotkey">P</span>ayment</a> ...but I'm not married to the idea of injecting a <span/> in there if there's a better way. How can I do this in CSS or JQuery? Is there a way to pass in a letter to a CSS style and have it change the color of the text displayed? Should I generate javascript to highlight the text when the page loads? What would/did you do in this situation?

• What's best choice career-wise, to know a little about a lot or a lot about a little?

  - by nimo

  I work as a developer at a rather small company and we are providing a web application that is used by a big base of customers. Because we are so small everyone have to be able to do a lot of different tasks. It ranges from advanced support, developing the product (programming: c/c++, c#, php, sql, javascript, html, css), handle network configuration and network related issues and even sometimes go on sales meetings with potential customers. My concern is that I don't really specialize in any specific area. I know and learn little about a lot. I have graduated from school two years ago and this is my first real employment and when I look at other positions out there they always require so and so many years of experience in a specific area (for example 5 years of C#). For me to get that kind of specialized experience will be really hard at my current job. My question for you is what is, in your opinion, best choice career-wise, to know a little about a lot or a lot about a little? What path did you take? pros and cons that comes with that choice.

• Micrsoft Silverlight 3 cannot create service reference to localhost:port

  - by Monte

  Windows Server 2003 (IIS 6) Visual Studio 2008 .NET FrameWork 3.5 SP1 I am a .NET developer for a living and I have over 40 hours in the problem Project type = "Silverlight Navigation Application", "APS.NET Web Site" (when I tried it as "ASP.NET Web Application Project" I could not copy it to the production web site - well I could copy it but I could not make it run) Created a service.cs on the .Web side of the application. Created a reference to that service.cs on the Silverlight side. For a time all is good as I can reference the service as localhost:port (e.g. localhost:1374) in Visual Studio and debug both Silverlight side and service.cs To access the application in production mode (from IE) I update the service refrence and replace localhost:port with the IP address. The problem with the IP address is I cannot debug the service.cs so I have to change it back to localhost:port to debug. Now to the problem. After a period of time localhost:port just plain breaks. I get an error message no service at the other end Yes I know the port can change - that is not the problem - the port on the service side just plain breaks! For example from Visual Studio from the Silverlight side of the project right click "Service Reference", "Add Service Reverence". It finds 1 service in the application on a port. But when I click that service under "Services:" in the modal dialog box "Add Service Reference" I get an error: There was an error downloading 'http://localhost:1377/SehaleCSS.Web/Service.svc'. The request failed with the error message: -- Could not load file or assembly 'App_Web_tipnndfq, If I go back to the IP address the service is repsponding (with the right answer) The service just plain goes a while responding to localhost:port and then fails Even making NO change to service.cs it go a while then fails as a localhost:port It is not IIS environmental as I can go back to a prior saved version of the code and it works Something is happening that the .web side of the application is failing. It still works as an IP and it still exposes itself as a localhost:port but it fails to properly repsonde as a localhost:port.

• Portable Eclipse

  - by Jeach

  I'm trying to port my entire 'workspace' to a USB key (including the Eclipse executable) so that I can carry my work anywhere with me and work off the key directly. My directory hierarchy is similar to this: /workspace/eclipse - Where my current eclipse binary is stored /workspace/codebase - Where I keep the root of all my eclipse projects /workspace/resources - Where I keep all project files (images, docs, libs, etc.) It all works perfectly fine on one system. But when I change over to another system, the USB key gets mounted on another drive. For example, on my laptop, I get 'E:\', on my PC, I get 'K:\' and at work I get 'F:\', etc, etc. This means that because Eclipse (for 'some' reason) seems to only use full path names (including driver letters) in every single one of its configuration files (such as .classpath), nothing ever works when I want to work on another system. I put a 'libs' directory in the base of every project and populate it with its dependent JAR files. Why doesn't it use relative names instead, so that I could specify something like "../../libs/log4j.jar"? Anyone know how to fix this problem? Does anyone know of a workaround for this? For some reason, I really doubt I'm the first developer to do this! Thanks for your help and any suggestions.

• How come the Actionscript 3 ENTER_FRAME event is crazy nuts?

  - by nstory

  So, I've been toying around with Flash, browsing through the documentation, and all that, and noticed that the ENTER_FRAME event seems to defy my expectation of a deterministic universe. Take the following example: (new MovieClip()).addEventListener(Event.ENTER_FRAME, function(ev) {trace("Test");}); Notice this anonymous MovieClip is not added to the display hierarchy, and any reference to it is immediately lost. It will actually print "Test" once a frame until it is garbage collected. How insane is that? The behavior of this is actually determined by when the garbage collector feels like coming around in all its unpredictable insanity! Is there a better way to create intermittent failures? Seriously. My two theories are that either the DisplayObject class stores weak references to all its instances for the purpose of dispatching ENTER_FRAME events, or, and much wilder, the Flash player actually scans the heap each frame looking for ENTER_FRAME listeners to pull on. Can any hardened Actionscript developer clue me in on how this works? (And maybe a why - the - f**k they thought this was a good idea?)

• Looking for a good C++/.net

  - by Michael Minerva

  I have recently started to feel that I need to greatly improve my C++ skills especially in the realm of .net. I graduated from a good four year university with a degree in computer science about 9 months ago and I have since been doing full time contract work for a small software company in my local area. Most of my work has been done using Java/lisp/cocoa/XML and before that most of my programming in my senior year was in java/C#. I did a decent amount of C++ in my Sophomore year and in my free time before that but I feel that my general knowledge of C++/.net is very lacking for the opportunities that are now coming my way. Can anyone recommend a good book that could help me get up too speed? I feel I do not need a very basic introduction to C++ but something that covers the fundamentals of .net would be good for me. So basically what I need is a book or books that would be good for a .net novice and a C++ developer who is just beyond novice. Also, a book that would help bein an interview by giving me a conversional understanding of C++ would be great. Thanks a lot!.

• Should I learn to code?

  - by saltcod

  Hi All, This is more of a philosophical question than a technical one, but I’d like some opinions on it, and I think that there are many others in my position that would benefit. My issue is that I don’t really have time to learn how to code. I know, I know… no one has time anymore, but please hear me out. Since learning to use Drupal about 2 years ago I’ve been involved with several projects wherein I’ve become the default quasi-developer, front-end designer, site manager, and system administrator. What I’ve found is that I can produce fairly nice, feature rich Drupal sites with the wealth of contrib. modules out there (Views, CCK, image handling, etc….). BUT! I can’t code. I know enough PHP to insert something into a block, or re-word a string, but that’s about it. I still don’t really even know how arrays work. My question Succinctly, my question is: Given the time that I have available for all of this stuff – in addition to a full-time job and regular life – am I better off trying to become more expert at the front-end stuff, or should I just learn PHP already? Pros 1. If a project doesn’t use Drupal, I’ll know enough PHP to be able to participate. 2. Learning PHP would help my Drupal development too 3. Learning PHP would make front-end theming easier 4. Learning PHP should give me that missing background in programming – and should allow me to learn other languages in the future Cons 1. At 28, I know I’m not too old to learn anything. But am I too old to become ‘good’? 2. Am I better off getting better and better at front-end UX work? 3. Am I better off farming out the PHP work? Suggestions from coders welcome! Thanks Terry

• Jquery (non-gem) plugin won't work in my rails 3.2 app

  - by jfdimark

  I'm trying to equalize columns in my rails 3.2 app, and while there may be a better way to do it then my current attempt, after hours of trying to make it work I'd like to see if anyone can point out specifically why this jQuery plugin (which isn't a gem) is not working. I'm not getting any errors in the developer console, so it's hard to pin point. Here's the relevant code: The index view, where I've followed the plugin's instructions: div id="column-group"> <div class="equalize span5 offset1 UserProfile"> <% if user_signed_in? %> <h3>Hello <%= current_user.name %>!</h3> </div> <div class="equalize span5 MemberDisplay"> My application.js file, where I've also included the specific js code, so it would definitely be picked up by the application: //= require jquery //= require jquery_ujs //= require bootstrap //= require equalize_column_heights //= require_tree . $(document).ready(function() { $("#column-group").equalize_column_heights("equalize"); }); The jQuery plugin code, which is saved in my vendor/assets/javascripts folder: (function ($) { $.fn.equalize_column_heights = function (equalize_class) { var tallest_column=0; parent_id = "column-group" + $(this).attr("id") + " ." + equalize_class; $(parent_id).each(function(index, value) { if (tallest_column < $(this).height()){ tallest_column = $(this).height(); } }); $(parent_id).each(function(index, value) { $(this).css({'min-height': tallest_column}); }); } }(jQuery)); I've read all the rails guides documentation on the asset pipeline and all the relevant jQuery-rails3 questions on SO, but after several hours, I just can't seem to figure this one out. If anyone can point to other tutorials on how to get non-gem jQuery plugins to work in a Rails 3.2 app then I'd be glad to take a look!

• Just for fun (C# and C++)...time yourself [closed]

  - by Ted

  Possible Duplicate: What is your solution to the FizzBuzz problem? OK guys this is just for fun, no flamming allowed ! I was reading the following http://www.codinghorror.com/blog/2007/02/why-cant-programmers-program.html and couldn't believe the following sentence... " I've also seen self-proclaimed senior programmers take more than 10-15 minutes to write a solution." For those that can't be bothered to read the article, the background is this: ....I set out to develop questions that can identify this kind of developer and came up with a class of questions I call "FizzBuzz Questions" named after a game children often play (or are made to play) in schools in the UK. An example of a Fizz-Buzz question is the following: Write a program that prints the numbers from 1 to 100. But for multiples of three print "Fizz" instead of the number and for the multiples of five print "Buzz". For numbers which are multiples of both three and five print "FizzBuzz". SO I decided to test myself. I took 5 minutes in C++ and 3mins in c#! So just for fun try it and post your timings + language used! P.S NO UNIT TESTS REQUIRED, NO OUTSOURCING ALLOWED, SWITCH OFF RESHARPER! :-) P.S. If you'd like to post your source then feel free

• What tools do you have at your disposal as a manager to promote a way of thinking

  - by John Leidegren

  This question goes beoynd just programming, but I'd like to get some input on this, if that's okay with the community. Preferably from people that do a lot of coding themselves but also manage other people coding. My problem is this. We have all these ideas that we know is good for the overall strategy of the company and the problem is not figuring out what to do, it's to come about this change. Just telling someone to do things differently isn't enough and it's hard to promote a mind set that is shared within all of the company, (this will take time). If I could jump forward I'd like it if we could create a very nurturing company culture that promotes these ideals cross all areas but I'm not sure what tools to use. And by tools I mean anything I'm legally permitted to do. e.g. we could talk about, we could arrange traning sessions, we could spend more time in meeting (talk about it more), we could spend more time designing, we could spend more time pair-programming, we could add/remove incentive or we could encurage more play. Ultimately if we did all of these things what will be the recurring theme that ties this together. I'd like to be able to answer the question -- why should we do things like this? -- and come up with an answer that explains how important it is to think about our ideals from begining to end. I've puposly avoided to talk about or specifics of the situtation becuase I believe that it narrows things down too much. But I guess, by know you either know how to answer this question or you're as confused as I am ;) I'd love to hear from people who had to bring about a change in order to go from chaos to order, or fix something in the organization which wasn't working. And I'd like to hear it from the perspective of the developer and designer. -- or -- You could simply weigh in on what are the most important qualities in an organization encurage or stimulate rigid fun development cycle from start to finish?

• Book/topic recommendations for a programmer returning to programming.

  - by Jason Tan

  I used to be a developer in Java, PHP, perl and C/C++ (the C++ bit badly - the others not too badly, I hope). This was back in the Java 1.3/1.4 days. We used raw JDBC, swing, servlets, JSP and ant (sometimes even make). Eclipse was new. Then I joined a deployment team and became a deployment engineer and then after the deployment engineer work became a full time sys admin.You get the idea - my experience is a generation or two old in programming terms - maybe older. I'm interested in getting back into Java and perhaps Ruby development, but feel I will be waaaaay behind the technological 8 ball. Can you folks suggest some books (or sites) that would be worth reading to catch up with the last 5-10 years of the development world. I.e. what should I read to try and catch up with where development is now? I see lots of stuff on the web, but what are people in the fabled "real world" using? (are lots of people being SOA based apps? Are they using XP methodology) The sorts of things I'm interested in finding out about/catching up on are: Methodologies Design patterns APIs/Frameworks/Technologies Other stuff you deem current/interesting/relevant. So if you have any thoughts or can recommend any books (especially new classics - you know the 's equivalent to K&R C or "The mythical man month"). Thanks for any thoughts you might share.

• How to use accessors within the same class in Objective C?

  - by Azeworai

  Hi, I have a few properties defined in my header file like so @property (assign) bool connectivity_N; @property (assign) bool isConnected_N; In my implementation file I have an init and the synthesized properties like so @implementation Map @synthesize connectivity_N; @synthesize isConnected_N; a init to set the initial values like so -(id) init { if( (self=[super init]) ) { //initialise default properties self.connectivity_N=NO; self.isConnected_N=NO; } return self; } I'm running into an error that states Error: accessing unknown 'connectivity_N' class method. In this public method within the class +(bool) isConnectable:(directions) theDirection{ bool isTheDirectionConnectable= NO; switch (theDirection) { case north: isTheDirectionConnectable= self.connectivity_N; break; I'm not sure why is this so as I'm trying to grab the value of the property. According to the apple developer documentation "The default names for the getter and setter methods associated with a property are propertyName and setPropertyName: respectively—for example, given a property “foo”, the accessors would be foo and setFoo:" That has given me a clue that I've done something wrong here, I'm fairly new to objective C so would appreciate anyone who spends the time to explain this to me. Thanks!

• Why my oracleParameter doesnt work?

  - by user1824356

  I'm a .NET developer and this is the first time i work with oracle provider (Oracle 10g and Framework 4.0). When i add parameter to my command in this way: objCommand.Parameters.Add("pc_cod_id", OracleType.VarChar, 4000).Value = codId; objCommand.Parameters.Add("pc_num_id", OracleType.VarChar, 4000).Value = numId; objCommand.Parameters.Add("return_value", OracleType.Number).Direction = ParameterDirection.ReturnValue; objCommand.Parameters.Add("pc_email", OracleType.VarChar, 4000).Direction = ParameterDirection.Output; I have no problem with the result. But when a add parameter in this way: objCommand.Parameters.Add(CreateParameter(PC_COD_ID, OracleType.VarChar, codId, ParameterDirection.Input)); objCommand.Parameters.Add(CreateParameter(PC_NUM_ID, OracleType.VarChar, numId, ParameterDirection.Input)); objCommand.Parameters.Add(CreateParameter(RETURN_VALUE, OracleType.Number, ParameterDirection.ReturnValue)); objCommand.Parameters.Add(CreateParameter(PC_EMAIL, OracleType.VarChar, ParameterDirection.Output)); The implementation of that function is: protected OracleParameter CreateParameter(string name, OracleType type, ParameterDirection direction) { OracleParameter objParametro = new OracleParameter(name, type); objParametro.Direction = direction; if (type== OracleType.VarChar) { objParametro.Size = 4000; } return objParametro; } All my result are a empty string. My question is, these way to add parameters are not the same? And if no, what is the difference? Thanks :) Add: Sorry i forgot mention "CreateParameter" is a function with multiple implementations the base is the above function, the other use that. protected OracleParameter CreateParameter(string name, OracleType type, object value, ParameterDirection direction) { OracleParameter objParametro = CreateParameter(name, type, value); objParametro.Direction = direction; return objParametro; } The last parameters doesn't need value because those are output parameter, those bring me data from the database.

• Visual SourceSafe (VSS): "Access to file (filename) denied" error

  - by tk-421

  Hi, can anybody help with the above SourceSafe error? I've spent hours trying to find a fix. I've also Googled the heck out of it but couldn't find a scenario matching mine, because in my case only a few files (not all) are affected. Here's what I found: only a few files in my project generate this error other files in the same directory (for example, App_Code has one of the problem files) work fine I've tried checking out from both the VSS client and Visual Studio another developer can check out the main problem file without any problems This sounds like a permission issue for my user, right? However: I found the location of one of the problem files in VSS's data directory (using VSS's naming format, as in 'fddaaaaa.a') and checked its permissions; everything looks fine and its permissions match those of other files I can check out successfully I can see no differences in the file properties between working and non-working files What else can I check? Has anyone encountered this problem before and found a solution? Thanks. P.S.: SourceGear, svn or git are not options, unfortunately. P.P.S.: Tried unsuccessfully to add tag "sourcesafe." EDIT: Hey Paddy, I tried to click 'add comment' to respond to your comment, but I'm getting a javascript error when loading this page in IE8 ("jquery undefined," etc.) so this isn't working. This is when checking out files, and yes, I've obliterated my local copy more times than I can remember. ;) EDIT 2: Thanks for the responses, guys (again I can't 'add comment' due to jQuery not loading, maybe blocked as discussed in Meta). If the problem was caused by antivirus or a bad disk, would other users still be able to check out the file(s)? That's the case here, which makes me think it's a permission issue specific to my account. However I've looked at the permissions and they match both other users' settings and settings on other files which I can check out.

• what patern is layerd architechture in asp.net ?

  - by haansi

  Hi, I am a asp.net developer and don't know much about patterns and architecture. I will very thankful if you can please guide me here. In my web applications I use 4 layers. Web site project (having web forms + code behind cs files, user controls + code behind cs files, master pages + code behind cs files) CustomTypesLayer a class library (having custom types, enumerations, DTOs, constructers, get, set and validations) BusinessLogicLayer a class library (having all business logic, rules and all calls to DAL functions) DataAccessLayer a class library( having just classes communicating to database.) -My user interface just calls BusinessLogicLayer. BusinessLogicLayer do proecessign in it self and for data it calls DataAccessLayer funtions. -Web forms do not calls directly DAL. -CustomTypesLayer is shared by all layers. Please guide me is this approach a pattern ? I though it may be MVC or MVP but pages have there code behind files as well which are confusing me. If it is no patren is it near to some patren ? pleaes guide thanks

• Manipulating/changing adressbar link Help

  - by Karem

  I am out of my own "ideas" going through this. I have a album viewer. When you click next I want the adressbar to hang with it, e.g if you start on ?photoid=1, and click next (next picture appends and stuff), and then i want it to say ?photoid=2. Now I cant make it say ?photoid=2 without changing/manipulating, and this you cant do without HTML5. I have made a script in HTML5 that works fine, but then I need to take care of those who dont have HTML5(only chrome, ff4 etc supports html5) Made the script from this( https://developer.mozilla.org/en/DOM/Manipulating_the_browser_history ) I thought of adding #photoid=2 so, ?photoid=1#photoid=2 and then check if theres anything in # then use that instead of the $_GET.. But apparently you cannot do that as # is client side handled and never sent to the server. So what should I then do? Any suggestions please to make a workaround this? I checked facebook, what they did to IE users, and I could hear that it "clicked" (the annoying click sound from IE) twice.. the first was to get to the next picture, the second click sound changed the adressbar?!(how?). And then I also thought hey, html5 is only supported in ff4, and I got ff3.6, and they manipulate the adress bar url when you browse through the album photos, exactly like how I wanted (and what I have written for but it only works in Chrome and ff4..?). How could they do that?

• Android and fairly large SQLite datafiles

  - by SK9

  I'm starting an Android project, a port from an existing iPhone project I've completed. I have a fairly large read-only SQLite database, about 100Mb in all. It's called "mydata.sqlite". Where do I place this in my Eclipse workspace? It's too big for "assets". Next, how do I best get at the file? I would think to try (handling exceptions later) something like: SQLiteDatabase myDatabase = null; myDatabase = SQLiteDatabase.openDatabase(myPath, null, SQLiteDatabase.OPEN_READONLY); But I would then need the path string myPath and since I don't know where to put the resource I don't know what this needs to be. Can I put "mydata.sqlite" into "res/raw" (once I create "raw" in Eclipse?) and then referene it as a resource with "R.raw.mydata"? I would very much appreciate some direct help here, rather than a reference to a tutorial. I have checked tons of these, including those that are already cited here on stackoverflow. I've also gone through the "Notepad" project in the Android developer documents. However these and the documentation typically consider only new, empty or small databases. This should be a simple thing and given the time I've spent already it is perhaps easier to ask. Thanking you kindly in advance for your assistance.

• .NET Development of iPhone App with MonoTouch - which development environment?

  - by Click Ahead

  Hi All, I'm a .NET developer (C#) with several years developing Windows Mobile Apps. I would like to get into developing iPhone Apps and MonoTouch looks good based on reviews I've read. So I'm going to go with MonoTouch. My understanding is that I'll need a new Mac, but as it happens I also need a new PC for my .NET windows development. My question is should I (a) Purchase a Mac Book Pro and dual boot with Windows 7 (b) Purchase a Mac Pro and dual boot with Windows 7 (c) Purchase a good Dev PC and a slighlty less well spec'd Mac Book Pro or Mac Pro Bear in mind I'm only doing MonoTouch development with the Mac, most of my development (approx. 80% initially) will be done on the Windows side. My budget is approx. €3,000 / $4,000 and I'd like a good, fast development environment.It's purely for development so on the windows side installing SQL 2008/VS 2010/Office and on the OS X side installing MonoTouch. BTW - my budget excludes licensing for VS/MonoTouch/etc, I have a MonoTouch and MSDN license. Any opinions are greatly appreciated. I'm a newbie to Mac's !

• accessing specific icons from a Multi-Icon (.ico) file

  - by Sagi1981

  Dear community. I would like to know if the following is possible. I have an .ico file, containing several sizes and color depths. However, it also contains some custom made sizes, that are going to be used inside my application. The application accesses the icon trough a resource DLL. (The intention is that the DLL is provided by a third party developer) Is there any way to pinpoint exactly which of the icons in the .ico file to use in my application? Like I want this size to appear here on my GUI etc. For instance, I am making a button in my application, and I would like my custom made 15*32 icon from my .ico file to be displayed on the button. I know this is possible by adding the bitmaps one at a time to the resource DLL, giving each of them a unique name. But it would be easier, if I am able to identify the different contents of the icon file instead. Is it possible in some way to look at the icon file as an array of icons or something like that? Any help is much appreciated. It seems quite hard to find information about this subject on the web. Oh, and I am writing my application in C#, using MFC DLL (from Visual C++ to create my resource DLL)

• Shortest Distance From An Array

  - by notyou61

  I have an ajax function which returns the latitudes and longitudes of locations stored in a database. These are returned and placed in an array. A calculation is performed to return their distance from the users current location based on the latitude/longitude. I would like to return only the record with the shortest calculated distance. My code is as follows: Ajax Success // Success success: function (data) { // Obtain Log/Lat navigator.geolocation.getCurrentPosition(function(position) { // Obtain Current Position Lat/Lon glbVar.latitude = position.coords.latitude; glbVar.longitude = position.coords.longitude; // Console Log //console.log('Lat: ' + glbVar.latitude + ' Lon: ' + glbVar.longitude); // Obtain Location Distances for ( var i = 0; i < data.length; i++ ) { // Location Instances var varLocation = data[i]; // Location Distance varLocation.distance = calculateDistance(glbVar.longitude, glbVar.latitude, varLocation.locationLongitude, varLocation.locationLatitude); } // Sort Locations By Distance var sortedData = data.sort(function(a, b) { // Return Locations return a.distance - b.distance; }); // Output Results $.map(sortedData, function(item) { // Obtain Location Distance varLocationsDistance = calculateDistance(glbVar.longitude, glbVar.latitude, item.locationLongitude, item.locationLatitude); // Obtain Location Radius Assignment if (varLocationsDistance <= varLocationRadius) { // Function Return functionReturn = $({locationID : item.locationID + ', Distance : ' + varLocationsDistance + ' m'}); // Return // Function to get the Min value in Array Array.min = function( sortedData ){ functionReturn = Math.min.apply( Math, sortedData ); // console.log(functionReturn); }; } }); }); } The calculateDistance function returns the distance from the users current location and those from the database. The varLocationsDistance <= varLocationRadius "If" statement returns records within a certain distance radius (100 meters), within that statement I would like to return the shortest distance. I am a self taught amateur web developer and as a result may not have provide enough information for an answer, please let me know. Thanks,
