• Best way to pan & scan images with jquery

  - by guy

  Hello, I am trying to make an image pan & scan system. I have a slider that zooms the image (that can be dragged) and also a small map in the corner of the image (that can also be dragged). You can see a rough example here (sorry, I am not allowed to use the design, so it's not formatted): http://lighe.madetokill.com/test/test.html My problem is that although it works great in firefox and opera, it stutters in chrome, safari and IE (it doesn't currently work in IE) at any zoom level except 100% (at 100% it's butter smooth). What is the reason for webkit's poor performance? Am I implementing this wrong? I am basically changing the margin-left and margin-top properties of the image. I know this is fast enough since at 100% it's perfectly smooth. Would I be better off using canvas? I am trying to avoid flash (or any other plugins) if possible. Also please note this is work in progress, there are other bugs except this, so do not bother with those :) Thanks in advance!

• Unit Testing using InternalsVisibleToAttribute requires compiling with /out:filename.ext?

  - by Will Marcouiller

  In my most recent question: Unit Testing Best Practice? / C# InternalsVisibleTo() attribute for VBNET 2.0 while testing?, I was asking about InternalsVisibleToAttribute. I have read the documentation on how to use it, and everything is fine and understood. However, I can't instantiate my class Groupe from my Testing project. I want to be able to instantiate my internal class in my wrapper assembly, from my testing assembly. Any help is appreciated! EDIT #1 Here's the compile-time error I get when I do try to instantiate my type: Erreur 2 'Carra.Exemples.Blocs.ActiveDirectory.Groupe' n'est pas accessible dans ce contexte, car il est 'Private'. C:\Open\Projects\Exemples\Src\Carra.Exemples.Blocs.ActiveDirectory\Carra.Exemples.Blocs.ActiveDirectory.Tests\GroupeTests.vb 9 18 Carra.Exemples.Blocs.ActiveDirectory.Tests (This says that my type is not accessible in this context, because it is private.) But it's Friend (internal)! EDIT #2 Here's a piece of code as suggested for the Groupe class implementing the Public interface IGroupe: #Region "Importations" Imports System.DirectoryServices Imports System.Runtime.CompilerServices #End Region <Assembly: InternalsVisibleTo("Carra.Exemples.Blocs.ActiveDirectory.Tests")> Friend Class Groupe Implements IGroupe #Region "Membres privés" Private _classe As String = "group" Private _domaine As String Private _membres As CustomSet(Of IUtilisateur) Private _groupeNatif As DirectoryEntry #End Region #Region "Constructeurs" Friend Sub New() _membres = New CustomSet(Of IUtilisateur)() _groupeNatif = New DirectoryEntry() End Sub Friend Sub New(ByVal domaine As String) If (String.IsNullOrEmpty(domaine)) Then Throw New ArgumentNullException() _domaine = domaine _membres = New CustomSet(Of IUtilisateur)() _groupeNatif = New DirectoryEntry(domaine) End Sub Friend Sub New(ByVal groupeNatif As DirectoryEntry) _groupeNatif = groupeNatif _domaine = _groupeNatif.Path _membres = New CustomSet(Of IUtilisateur)() End Sub #End Region And the code trying to use it: #Region "Importations" Imports NUnit.Framework Imports Carra.Exemples.Blocs.ActiveDirectory.Tests #End Region <TestFixture()> _ Public Class GroupeTests <Test()> _ Public Sub CreerDefaut() Dim g As Groupe = New Groupe() Assert.IsNotNull(g) Assert.IsInstanceOf(Groupe, g) End Sub End Class EDIT #3 Damn! I have just noticed that I wasn't importing the assembly in my importation region. Nope, didn't solve anything =( Thanks!

• rails + compass: advantages vs using haml + blueprint directly

  - by egarcia

  I've got some experience using haml (+sass) on rails projects. I recently started using them with blueprintcss - the only thing I did was transform blueprint.css into a sass file, and started coding from there. I even have a rails generator that includes all this by default. It seems that Compass does what I do, and other things. I'm trying to understand what those other things are - but the documentation/tutorials weren't very clear. These are my conclusions: Compass comes with built-in sass mixins that implement common CSS idioms, such as links with icons or horizontal lists. My solution doesn't provide anything like that. (1 point for Compass). Compass has several command-line options: you can create a rails project, but you can also "install" it on an existing rails project. A rails generator could be personalized to do the same thing, I guess. (Tie). Compass has two modes of working with blueprint: "basic" and "semantic" usage. I'm not clear about the differences between those. With my rails generator I only have one mode, but it seems enough. (Tie) Apparently, Compass is prepared to use other frameworks, besides blueprint (e.g. YUI). I could not find much documentation about this, and I'm not interested on it anyway - blueprint is ok for me (Tie). Compass' learning curve seems a bit stiff and the documentation seems sparse. Learning could be a bit difficult. On the other hand, I know the ins and outs of my own system and can use it right away. (1 point for my system). With this analysis, I'm hesitant to give Compass a try. Is my analysis correct? Are Am I missing any key points, or have I evaluated any of these points wrongly?

• Why isn’t my autoreleased object getting released?

  - by zoul

  Hello. I am debugging a weird memory management error and I can’t figure it out. I noticed that some of my objects are staying in memory longer than expected. I checked all my memory management and finally got to the very improbable conclusion that some of my autorelease operations don’t result in a release. Under what circumstances is that possible? I created a small testing Canary class that logs a message in dealloc and have the following testing code in place: NSLog(@"On the main thread: %i.", [NSThread isMainThread]); [[[Canary alloc] init] autorelease]; According to the code we’re really on the main thread, but the dealloc in Canary does not get called until much later. The delay is not deterministic and can easily take seconds or more. How is that possible? The application runs on a Mac, the garbage collection is turned off (Objective-C Garbage Collection is set to Unsupported on the target.) I am mostly used to iOS, is memory management on OS X different in some important way?

• VS2010 / Target Framework = 3.5 / Building on Continuous Integration Server

  - by granadaCoder

  I'm checking into upgrading to VS2010. Our production servers only have 3.5 Framework and it will be 6-9 months before they are updated. We also have a Continuous Integration Server, running CruiseControl.NET (CC.NET). It has the 3.5 Framework on it as well. Our implementation of CC.NET mainly calls msbuild.exe MySolution.msbuild. (We encapsulate most of the build logic into .msbuild files fyi) Inside the .msbuild file, the following is the "Build" syntax: < Target Name="Build" DependsOnTargets="Checkout" < MSBuild Projects="$(WorkingCheckout)\MySolution.sln" Targets="Build" Properties="Configuration=$(Configuration)" < Output TaskParameter="TargetOutputs" ItemName="TargetOutputsItemName"< /Output < /MSBuild < /Target (A few spaces added to make it display here) =========== I know the VS2010 can "Target" the 3.5 Framework. My question is what happens when I have a VS2010 dev machine, and I check the VS2010 .sln and .csproj(s) files into source control (svn, btw).....will the CC.NET machine ~~which only have the 3.5 Framework installed on it........be able to build the .sln ? I guess I could test it, but the catch22 is that I don't have VS2010 (yet). So I'm asking before I try (the trial or a real install. ............. Any ideas what will happen? I guess the crux question is, what will happen. c:\WINDOWS\Microsoft.NET\Framework\v3.5\MSBuild.exe "MyVS2010SolutionFile.sln" ?? My hopeful goal would be, allow the developers to have VS2010 (now!), and it still be "ok" for the CC.NET machine and the Production Servers which will only have the 3.5 Framework on them for the foreseeable future. Just to be clear, developers NEVER create deployable builds. Only the CC.NET machine produces builds that will be pushed as production builds. Any help?

• Question about Multicast Delegates?

  - by IbrarMumtaz

  I am going through some exam questions for the 70-536 exam and an actual question one developer posted on his blog has popped up in my exam questions. I cannot remember what his answer was .... but below is the question: You need to write a multicast delegate that accepts a DateTime argument and returns a bool value. Which code segment should you use? A: public delegate int PowerDeviceOn(bool, DateTime) B: public delegate bool PowerDeviceOn(Object, EventArgs) C: public delegate void PowerDeviceOn(DateTime) D: public delegate bool PowerDeviceOn(DateTime) The answer is A. Can someone please explain why? As I already did some research into this question a while ago and so I was sure that it was C, obviously now looking back at the question its clear that I did not read properly. As i was sure I had seen the same one before so I jumped to the most obvious one. A variation on this question: You need to write a multicast delegate that accepts a DateTime argument. Which code segment should you use? A: public delegate int PowerDeviceOn(bool, DateTime) B: public delegate bool PowerDeviceOn(Object, EventArgs) C: public delegate void PowerDeviceOn(DateTime) D: public delegate bool PowerDeviceOn(DateTime) Now this is another variation on this question, it still has the same bogus sample answers, as they still kind work in throwing the exam taker off. Notice how by simply keeping the sample answers the same and by removing a small portion of the question text, the answer is C and not A. The variation has no official answer as I just conjured it up using the exam question as a baseplate. The answer is definitely C. This time round its easy to see why C is correct but the very first question I have an inkling but as you know an inkling is not good enough in passing exams. Thanks For Reading.

• C# FileStream position is off after calling ReadLine()

  - by Cristi Diaconescu

  I'm trying to read a (small-ish) file in chunks of a few lines at a time, and I need to return to the beginning of particular chunks. The problem is, after the very first call to streamReader.ReadLine(); the streamReader.BaseStream.Position property is set to the end of the file! Now I assume some caching is done in the backstage, but I was expecting this property to reflect the number of bytes that I used from that file. For instance, calling ReadLine() again will (naturally) return the next line in the file, which does not start at the position previously reported by streamReader.BaseStream.Position. My question is, how can I find the actual position where the 1st line ends, so I can return there later? I can only think of manually doing the bookkeeping, by adding the lengths of the strings returned by ReadLine(), but even here there are a couple of caveats: ReadLine() strips the new-line character(s) which may have a variable length (is is '\n' ? is it "\r\n" ? etc) I'm not sure if this would work ok with variable-length characters ...so right now it seems like my only option is to rethink how I parse the file, so I don't have to rewind. If it helps, I open my file like this: using (var reader = new StreamReader( new FileStream(m_path, FileMode.Open, FileAccess.Read, FileShare.ReadWrite))) {...} Any suggestions?

• Android: ListActivity design - changing the content of the List Adapter

  - by Rob

  Hi, I would like to write a rather simple content application which displays a list of textual items (along with a small pic). I have a standard menu in which each menu item represents a different category of textual items (news, sports, leisure etc.). Pressing a menu item will display a list of textual items of this category. Now, having a separate ListActivity for each category seems like an overkill (or does it?..) Naturally, it makes much more sense to use one ListActivity and replace the data of its adapter when each category is loaded. My concern is when "back" is pressed. The adapter is loaded with items of the current category and now I need to display list of the previous category (and enable clicking on list items too...). Since I have only one activity - I thought of backup and load mechanism in onPause() and onResume() functions as well as making some distinction whether these function are invoked as a result of a "new" event (menu item selected) or by a "back" press. This seems very cumbersome for such a trivial usage... Am I missing something here? Thanks, Rob

• Scalable / Parallel Large Graph Analysis Library?

  - by Joel Hoff

  I am looking for good recommendations for scalable and/or parallel large graph analysis libraries in various languages. The problems I am working on involve significant computational analysis of graphs/networks with 1-100 million nodes and 10 million to 1+ billion edges. The largest SMP computer I am using has 256 GB memory, but I also have access to an HPC cluster with 1000 cores, 2 TB aggregate memory, and MPI for communication. I am primarily looking for scalable, high-performance graph libraries that could be used in either single or multi-threaded scenarios, but parallel analysis libraries based on MPI or a similar protocol for communication and/or distributed memory are also of interest for high-end problems. Target programming languages include C++, C, Java, and Python. My research to-date has come up with the following possible solutions for these languages: C++ -- The most viable solutions appear to be the Boost Graph Library and Parallel Boost Graph Library. I have looked briefly at MTGL, but it is currently slanted more toward massively multithreaded hardware architectures like the Cray XMT. C - igraph and SNAP (Small-world Network Analysis and Partitioning); latter uses OpenMP for parallelism on SMP systems. Java - I have found no parallel libraries here yet, but JGraphT and perhaps JUNG are leading contenders in the non-parallel space. Python - igraph and NetworkX look like the most solid options, though neither is parallel. There used to be Python bindings for BGL, but these are now unsupported; last release in 2005 looks stale now. Other topics here on SO that I've looked at have discussed graph libraries in C++, Java, Python, and other languages. However, none of these topics focused significantly on scalability. Does anyone have recommendations they can offer based on experience with any of the above or other library packages when applied to large graph analysis problems? Performance, scalability, and code stability/maturity are my primary concerns. Most of the specialized algorithms will be developed by my team with the exception of any graph-oriented parallel communication or distributed memory frameworks (where the graph state is distributed across a cluster).

• Source of parsers for programming languages?

  - by Arkaaito

  I'm dusting off an old project of mine which calculates a number of simple metrics about large software projects. One of the metrics is the length of files/classes/methods. Currently my code "guesses" where class/method boundaries are based on a very crude algorithm (traverse the file, maintaining a "current depth" and adjusting it whenever you encounter unquoted brackets; when you return to the level a class or method began on, consider it exited). However, there are many problems with this procedure, and a "simple" way of detecting when your depth has changed is not always effective. To make this give accurate results, I need to use the canonical way (in each language) of detecting function definitions, class definitions and depth changes. This amounts to writing a simple parser to generate parse trees containing at least these elements for every language I want my project to be applicable to. Obviously parsers have been written for all these languages before, so it seems like I shouldn't have to duplicate that effort (even though writing parsers is fun). Is there some open-source project which collects ready-to-use parser libraries for a bunch of source languages? Or should I just be using ANTLR to make my own from scratch? (Note: I'd be delighted to port the project to another language to make use of a great existing resource, so if you know of one, it doesn't matter what language it's written in.)

• In need of help with setting up the open source library JFreeChart

  - by ssbellows

  I am having trouble with setting up the open source library JFreeChart for creating charts using Java. This is the process I have followed so far in trying to set it up: I downloaded the latest version from their download page http://sourceforge.net/projects/jfreechart/files/. I then unpacked the jfreechart-1.0.13.zip in the directory C:\JFreeChart\jfreechart-1.0.13\ on my system drive. In the unpacked directory there is a folder entitled "lib" which contains the packaged .jar files specified as necessary to use JFreeChart. I added the following directory to my classpath: C:\JFreeChart\jfreechart-1.0.13\lib\ I then created a simple program and added the line "import org.jfree.chart.*;" to see if it would compile with a package imported from JFreeChart. I navigated to the folder in which my sample program was contained and compiled with the following command: "javac -classpath C:\ Program.java" I was given the following error: "package org.jfree.chart does not exist" Could someone please give me some input as to what I have done incorrectly in this setup process? This is the first time I've tried using an open source library, so I don't have any prior experience to go on myself. Thank you very much in advance.

• COMException in System.WIndows.Forms.dll with Interactive Brokers TWS API

  - by Lirik

  Hi, I've been trying to run the sample project provided with the tutorial at stockbotprogramming http://www.stockbotprogramming.com/sharpcibtutorial1.php , but I keep getting a COMException every time I run the application. I have the TWS Client running and the sample VB projects provided with the API are able to connect just fine, but when I try to use the C# sample provided by the tutorial then I get the following exception: An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in System.Windows.Forms.dll Th exception happens when I try to add the TWS ActiveX control: namespace CSharpTutorial1 { public partial class Form1 : Form { private AxTWSLib.AxTws tws; public Form1() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) { tws = new AxTWSLib.AxTws(); tws.BeginInit(); tws.Enabled = true; tws.Location = new System.Drawing.Point(32, 664); tws.Name = "tws"; Controls.Add(tws); // <-- EXCEPTION HERE! tws.EndInit(); tws.connect("127.0.0.1", 7496, 0); String msg = "Connected to TWS server version " + tws.serverVersion + "at " + tws.TwsConnectionTime; MessageBox.Show(msg); } } } Does anybody know what could be causing this exception? Any ideas on how to fix it?

• Guice, JDBC and managing database connections

  - by pledge

  I'm looking to create a sample project while learning Guice which uses JDBC to read/write to a SQL database. However, after years of using Spring and letting it abstract away connection handling and transactions I'm struggling to work it our conceptually. I'd like to have a service which starts and stops a transaction and calls numerous repositories which reuse the same connection and participate in the same transaction. My questions are: Where do I create my Datasource? How do I give the repositories access to the connection? (ThreadLocal?) Best way to manage the transaction (Creating an Interceptor for an annotation?) The code below shows how I would do this in Spring. The JdbcOperations injected into each repository would have access to the connection associated with the active transaction. I haven't been able to find many tutorials which cover this, beyond ones which show creating interceptors for transactions. I am happy with continuing to use Spring as it is working very well in my projects, but I'd like to know how to do this in pure Guice and JBBC (No JPA/Hibernate/Warp/Reusing Spring) @Service public class MyService implements MyInterface { @Autowired private RepositoryA repositoryA; @Autowired private RepositoryB repositoryB; @Autowired private RepositoryC repositoryC; @Override @Transactional public void doSomeWork() { this.repositoryA.someInsert(); this.repositoryB.someUpdate(); this.repositoryC.someSelect(); } } @Repository public class MyRepositoryA implements RepositoryA { @Autowired private JdbcOperations jdbcOperations; @Override public void someInsert() { //use jdbcOperations to perform an insert } } @Repository public class MyRepositoryB implements RepositoryB { @Autowired private JdbcOperations jdbcOperations; @Override public void someUpdate() { //use jdbcOperations to perform an update } } @Repository public class MyRepositoryC implements RepositoryC { @Autowired private JdbcOperations jdbcOperations; @Override public String someSelect() { //use jdbcOperations to perform a select and use a RowMapper to produce results return "select result"; } }

• SQL Server 2008 - Editing Tables: Bit columns require 'True' or 'False'

  - by CJM

  Not so much a question as an observation... I'm just upgrading to SQL Server 2008 on my development machine in anticipation of upgrading my live applications. I didn't anticipate any problems since [I think] I generally use standard T-SQL, and probably not too far from ANSI standard SQL. So far so good, but I was really thrown by a very simple change: I was creating a simple, small look-up table to store a list of codes and including a bit column to indicate the current default code. But when I used the new/modified 'Edit Top 200 Rows' option, and entered my 0s and 1s in the the bit column I got an error: 'Invalid value for cell - String was not recognised as a valid boolean' After a bit of head-scratching, I tried True and False - and they worked. So it seems this new Edit feature requires 4 or 5 characters to be typed, rather than the previous 1. Checking further, we can still use '...where bitval = 1' but can now also use '...where bitval = 'true''. But any results returned render these bit columns as 0 or 1 still. It all sounds like half a step backwards. Not the end of the world, but and unnecessary annoyance. Does anybody have any insight on this issue? Or there any other new Gotchas with SQL Server 2008?

• xp_smtp_sendmail blank space added to html randomly

  - by Igor Timofeyev

  I have a proc where I generate small html doc with a link and send it out via xp_smtp_sendmail proc. Link is generated based on query results and is long. This works in most cases. However, sometimes the link gets broken due to spaces being inserted into querystring variable names, i.e. &Na me=John. This might vary between email clients(same link works in Gmail, but might not work in comcast due to spaces. The space seems to be randomly inserted, so in each broken email link space might break other querystring variables. When I do PRINT from proc the link is clean, no spaces. Here's my sample of the mail proc being executed within main proc(that gets query results and generates html for @Message). The space seems to be inserted regardless of whether I encode the url or not. Thank you in advance for your help. I can send a cleaner version of the code if it's not displayed properly here. ....query results above SET @Message = NULL SET @Message = @Message + + '<br/>Dear ' + @FirstName + ' ' + @LastName + ',' + '<br/><br/>Recently you took "' + @Title + '".

• Where can I find free and open data?

  - by kitsune

  Sooner or later, coders will feel the need to have access to "open data" in one of their projects, from knowing a city's zip to a more obscure information such as the axial tilt of Pluto. I know data.un.org which offers access to the UN's extensive array of databases that deal with human development and other socio-economic issues. The other usual suspects are NASA and the USGS for planetary data. There's an article at readwriteweb with more links. infochimps.org seems to stand out. Personally, I need to find historic commodity prices, stock values and other financial data. All these data sets seem to cost money however. Clarification To clarify, I'm interested in all kinds of open data, because sooner or later, I know I will be in a situation where I could need it. I will try to edit this answer and include the suggestions in a structured manners. A link for financial data was hidden in that readwriteweb article, doh! It's called opentick.com. Looks good so far! Update I stumbled over semantic data in another question of mine on here. There is opencyc ('the world's largest and most complete general knowledge base and commonsense reasoning engine'). A project called UMBEL provides a light-weight, distilled version of opencyc. Umbel has semantic data in rdf/owl/skos n3 syntax. The Worldbank also released a very nice API. It offers data from the last 50 years for about 200 countries

• Using a profile property of type List in .NET Membership

  - by hancock

  Hi, I'm working on a C# Webservice that needs to provide authentication as well as roles and profile management. I need each profile to have a property of type List. The profile section in the web.config looks like this: <profile defaultProvider="MyProfileProvider" enabled="true"> <providers> <remove name="MyProfileProvider"/> <add connectionStringName="MySqlServer" applicationName="MyApp" name="MyProfileProvider" type="System.Web.Profile.SqlProfileProvider" /> </providers> <properties> <add name="Websites" type="System.Collections.Generic.List&lt;String&gt;" serializeAs="Binary"/> </properties> </profile> However, when I start the webservice and try to access that property it returns the following error: System.Configuration.ConfigurationErrorsException: Attempting to load this property's type resulted in the following error: Could not load type 'System.Collections.Generic.List<String>'. (C:\Projects\MyProject\web.config line 58) --- System.Web.HttpException: Could not load type 'System.Collections.Generic.List<String>'. Is there a way to use a generic collection for this purpose?

• Simulate Windows Service with ASP.NET

  - by Bayonian

  Hi, I have small web app that generate PDF files as a report. I'm trying to delete those generated PDF files after 10 sec that they are generated. What I want to do is to read a folder with PDF files every 10 sec, and delete all the PDF files inside that folder. I read this post of Easy Background Tasks in ASP.NET.

• Trying to save file from Flash to PHP using $GLOBALS["HTTP_RAW_POST_DATA"]

  - by jolyonruss

  Let me start by saying PHP isn't my forte, I'm usually reluctant to try working with it because of problems exactly like this. The code works fine on my local machine under MAMP and on my server, but doesn't on the clients server :'( So what am I trying to do, well - save an image from Flash onto the server, simple right?! I'm using the method described on this site here: http://designreviver.com/tutorials/actionscript-3-jpeg-encoder-revealed-saving-images-from-flash/ but have made a small alteration so that instead of echoing the jpg causing the browser to download it locally, I do an fwrite and an fclose to save it to the server. Here is my PHP: $imageFile = '../images/' . $_GET['name']; $imageHandle = fopen($imageFile, "w"); fwrite($imageHandle, $jpg); fclose($imageHandle); } ? I've dona a phpinfo() on my clients server and it's running 5.2.2 my host is running 5.2.11 I don't know if much can have changed in those 9 minor revisions? I've also read another question on here which suggests making suer always_populate_raw_post_data is set to ON, but it's set to OFF on all of the server environments I've been testing in. I'm doing some XML saving using file_get_contents('php://input') which I've tried but failed to get working with images. Any help would be gratefully received, I'm happy to post the AS3 as well but it's EXACTLY the same as example I've linked above and works locally. As far as I can tell the problem lies with the PHP. Cheers.

• E-commerce platform for custom application integration

  - by Zach Smith

  We are building an online subscription-based website and I'm looking for recommendations on which e-commerce platform to use for the checkout process. Requirements include: Only four products. The sign-up process of the site is heavily customized, and after checkout the user should automatically get logged into the subscriber area. Subscriptions will last one year and can be renewed manually. Support for coupons/discount codes at a later point. Since the entire application is custom, we've weighed building a custom checkout but are strongly leaning towards using existing software to avoid having to build lots of admin reporting as well as a coupon engine down the road. The two questions we're pondering are: Is it better to a) build our application custom and use whatever e-commerce software we select just for the payment piece, or b) use the e-commerce software as the basis and build our application around it/as a module/etc? Which e-commerce platform should we use? I've looked into a variety of off the shelf e-commerce software, but it's not clear to me which would be easiest to integrate with. I've researched on the Web and looked at many of the threads on SO to compiled a list of potential candidates: www.magentocommerce.com/ (seems difficult to integrate with) www.prestashop.com/ www.nopcommerce.com/ www.opencart.com/ www.cubecart.com/ www.spreecommerce.com/ www.interspire.com/ www.tradingeye.com/ We're most concerned with the level of effort required with ramping up on the software and then doing the integration with our custom functionality. We're most proficient with PHP, ASP.NET and some ROR and are only considering those technologies. We prefer open source, but would be open to commercial if there's a significant upside. Any experiences with similar projects and advice is greatly appreciated.

• Understanding floating point problems

  - by Maxim Gershkovich

  Could someone here please help me understand how to determine when floating point limitations will cause errors in your calculations. For example the following code. CalculateTotalTax = function (TaxRate, TaxFreePrice) { return ((parseFloat(TaxFreePrice) / 100) * parseFloat(TaxRate)).toFixed(4); }; I have been unable to input any two values that have caused for me an incorrect result for this method. If I remove the toFixed(4) I can infact see where the calculations start to lose accuracy (somewhere around the 6th decimal place). Having said that though, my understanding of floats is that even small numbers can sometimes fail to be represented or have I misunderstood and can 4 decimal places (for example) always be represented accurately. MSDN explains floats as such... This means they cannot hold an exact representation of any quantity that is not a binary fraction (of the form k / (2 ^ n) where k and n are integers) Now I assume this applies to all floats (inlcuding those used in javascript). Fundamentally my question boils down to this. How can one determine if any specific method will be vulnerable to errors in floating point operations, at what precision will those errors materialize and what inputs will be required to produce those errors? Hopefully what I am asking makes sense.

• Pattern for sharing data between views (MVP or MVVM)

  - by Dovix

  What is a good pattern for sharing data between related views?. I have an application where 1 form contains many small views, each views behaves independently from each other more or less (they communicate/interact via an event bus). Every so often I need to pass the same objects to the child views. Sometimes I need this same object to be passed to a child view and then the child passes it onto another child itself contains. What is a good approach to sharing this data between all the views contained within the parent form (view) ? I have looked into CAB and their approach and every "view" has a "root work item" this work item has dictionary that contains a shared "state" between the views that are contained. Is this the best approach? just a shared dictionary all the views under a root view can access? My current approach right now is to have a function on the view that allows one to set the object for that view. Something like view.SetCustomer(Customer c); then if the view contains a child view it knows to set it on the child view ala: this.childview1.SetCustomer(c); The application is written in C# 3.5, for winforms using MVP with structure map as a IoC/DI provider.

• .NET Working with Locking and Threads

  - by aherrick

  Work on this small test application to learn threading/locking. I have the following code, I would think that the line should only write to console once. However it doesn't seem to be working as expected. Any thoughts on why? What I'm trying to do is add this Lot object to a List, then if any other threads try and hit that list, it would block. Am i completely misusing lock here? class Program { static void Main(string[] args) { int threadCount = 10; //spin up x number of test threads Thread[] threads = new Thread[threadCount]; Work w = new Work(); for (int i = 0; i < threadCount; i++) { threads[i] = new Thread(new ThreadStart(w.DoWork)); } for (int i = 0; i < threadCount; i++) { threads[i].Start(); } // don't let the console close Console.ReadLine(); } } public class Work { List<Lot> lots = new List<Lot>(); private static readonly object thisLock = new object(); public void DoWork() { Lot lot = new Lot() { LotID = 1, LotNumber = "100" }; LockLot(lot); } private void LockLot(Lot lot) { // i would think that "Lot has been added" should only print once? lock (thisLock) { if(!lots.Contains(lot)) { lots.Add(lot); Console.WriteLine("Lot has been added"); } } } }
