• PHP float bug: PHP Hangs On Numeric Value

  - by jeroen

  I just read an interesting article about php hanging on certain float numbers, see The Register and Exploring Binary. I never explicitly use floats, I use number_format() to clean my input and display for example prices. Also, as far as I am aware, all input from for example forms are strings until I tell them otherwise so I am supposing that this problem does not affect me. Am I right, or do I need to check for example Wordpress and Squirrelmail installations on my server to see if they cast anything to float? Or better, grep all php files on my servers for float?

• Tracing\profiling instructions

  - by LeChuck2k

  Hi Y'all. I'd like to statistically profile my C code at the instruction level. I need to know how many additions, multiplications, devides, etc,... I'm performing. This is not your usual run of the mill code profiling requirement. I'm an algorithm developer and I want to estimate the cost of converting my code to hardware implementations. For this, I'm being asked the instruction call breakdown during run-time (parsing the compiled assembly isn't sufficient as it doesn't consider loops in the code). After looking around, It seems VMWare may offer a possible solution, but I still couldn't find the specific feature that will allow me to trace the instruction call stream of my process. Are you aware of any profiling tools which enable this?

• How to store user-specific data in SharePoint

  - by Paul-Jan

  I have some user-specific data that I need to store in SharePoint and make accessible to the user through custom webparts. Let's say a list of favorite URLs. What would be the most straightforward way to store this information? Some builtin propertybag for SPUser or similar that I'm not aware of. SPList, associated through User column. Custom database table, associated through SPUser ID. Otherwise? Sounds like a RTFM to me, but I'm probably asking google the wrong questions.

• Check if server exists

  - by buhtla

  Here is the problem. User can enter server name and connection string for database. If server is not accessible (wrong address, firewalls or any other issue), I want to be aware of this as quickly as possible. If I'm using sqlConnection and try to connect to a non-accessible server this takes very long (I think more than 1 minute!). This has nothing to do with connection timeout btw so setting this property won't help. My idea is to first try to ping server and if I get response (which means server is accessible from the point of application), than proceed with sqlConnection. If there is no response from ping, operation is aborted and user is properly notified. Is there any better way of doing this? Any idea would be welcome.

• Log with timestamps that have millisecond accuracy & resolution in Windows C++

  - by Psychic

  I'm aware that for timing accuracy, functions like timeGetTime, timeBeginPeriod, QueryPerformanceCounter etc are great, giving both good resolution & accuracy, but only based on time-since-boot, with no direct link to clock time. However, I don't want to time events as such. I want to be able to produce an exact timestamp (local time) so that I can display it in a log file, eg 31-12-2010 12:38:35.345, for each entry made. (I need the millisecond accuracy) The standard Windows time functions, like GetLocalTime, whilst they give millisecond values, don't have millisecond resolution, depending on the OS running. I'm using XP, so I can't expect much better than about a 15ms resolution. What I need is a way to get the best of both worlds, without creating a large overhead to get the required output. Overly large methods/calculations would mean that the logger would start to eat up too much time during its operation. What would be the best/simplest way to do this?

• Nesting quotes in JavaScript/HTML

  - by Ryan Elkins

  How do you nest quotes in HTML beyond the second level? As far as I know, there are only 2 types of quotes - single(') and double("). I am aware of escaping - you have to escape in the code but it converts the escaped quotes back to regular quotes when it hits the browser. What is the accepted method to get around something like the following? <p onclick="exampleFunc('<div id="divId"></div>');">Some Text</p> That code prints to the browser: ');"Some Text

• C#: Why only integral enums?

  - by JamesBrownIsDead

  I've been writing C# for seven years now, and I keep wondering, why do enums have to be of an integral type? Wouldn't it be nice to do something like: enum ErrorMessage { NotFound: "Could not find", BadRequest: "Malformed request" } Is this a language design choice, or are there fundamental incompatibilities on a compiler, CLR, or IL level? Do other languages have enums with string or complex (i.e. object) types? What languages? (I'm aware of workarounds; my question is, why are they needed?) EDIT: "workarounds" = attributes or static classes with consts :)

• Visual Studio Unit Testing of Windows Forms

  - by GWLlosa

  We're working on a project here in Visual Studio 2008. We're using the built-in testing suite provided with it (the Microsoft.VisualStudio.TestTools.UnitTesting namespace). It turns out, that much to our chagrin, a great deal of complexity (and therefore errors) have wound up coded into our UI layer. While our unit tests do a decent job of covering our business layer, our UI layer is a constant source of irritation. We'd ideally like to unit-test that, as well. Does anyone know of a good "Microsoft-compatible" way of doing that in visual studio? Will it introduce some sort of conflict to 'mix' unit testing frameworks like nUnitForms with the Microsoft stuff? Are there any obvious bear traps I should be aware of with unit-testing forms?

• Are QR codes guaranteed to work?

  - by Kiz

  Not sure if this will get closed as "not a real question" but I asked this on Superuser and it was closed for that very reason. We are thinking of implementing a QR code which will be sent to a number of users via an email which links through to a webpage. Now I'm aware that you can just Google 'QR codes' and there are a plethora of options that allow you to make a QR code. My question is thus; if we do go with this solution can we guarantee that it would work cross platform? I.e. on Android, iOS, Symbian etc? Once a QR code is generated will it work on ANY app on ANY platform? Thanks and apologies if this is not really a 'programming question' Thanks Kiran

• Will a Response.Redirect exception go to global.asax?

  - by mgmedick

  I'm aware that when you call Response.Redirect it fires a ThreadAbortException. A co-worker has demonstrated calling response.redirect and then it goes to the global.asax. For the life of me I cannot get the ThreadAbortException to go to the global.asax, its like it is being suppressed naturally in the system. The reason I'm asking this is we believe the response.redirect is the cause of some automated error emails, but I'm not convinced this is the case especially if I can't even get it to debug into the global.asax. Any Ideas why I can't get the Response.Redirect to fire the global error handler?

• Address calling class

  - by Samuel

  I have an abstract class Moveable with the method abstract void move() which is extended by the class Bullet and the abstract class Character, and Character is extended by the class Survivor and the class Zombie. In Survivor and Bullet the move() method doesnt require any parameters while in the class Zombie the move() method depends on the actual position of the survivor. The survivor and multiple zombies are created in the class Gui. I wanted to access the survivor in Zombie - what's the best way of doing this? In Gui i wrote a method getSurvivor() but i don't see how to access this method in Zombie? I am aware that as a workaround i could just pass a [Survivor survivor] as parameter in move() and ignore it in Bullet and Survivor, but that feels so ... bad practice.

• Tool to automatically add tracing or instrumentation to an .NET app?

  - by Tony_Henrich

  I have a .NET app which runs once a day. Sometimes there's a logical error somewhere which occurs randomly. Is there a tool like Eqatec's Tracer which automatically injects instrumentation in the code and logs everything to a file? The issue with Eqatec's Tracer is that it opens a window on the machine and it doesn't seem to log. My issue rarely occurs and I need to keep all logs for a long time. I don't want to change the source code and add logging statements all over the place. I am aware of PostSharp & Logfaces.

• [JavaScript] How can I load static configuration information

  - by Goro

  In my code, I use JavaScript for UI and PHP for back end. I also use PHP to store application settings and sometimes my UI code needs to access this information. My configuration file looks something like this (config.php): $resolution_x = 1920; $resolution_y = 1080; etc... When I need to access any of these settings form JavaScript, i simply use to substitute the value directly, but it just doesn't strike me as very robust. Are they any dangers of doing this that I am not aware of? Is there a better way of doing this? Thank you,

• What are the advantages / disadvantages of a Cloud-based / Web-based IDE?

  - by Gabe

  I'm writing this as DevConnections in Las Vegas is happening. Visual Studio 2010 has been released and I now have this 3GB beast installed to my machine. (I'll admit, it has some nice features.) However, while the install was monopolizing my computer's resources I began to wish that my IDE worked more like Google Documents (instantly available, available anywhere, easy to share, easy to collaborate, naturally versioned). A few Google (and StackOverflow) searches led me to : Coderun Bespin I'm well aware that these IDE's are missing a lot of what exists in VS 2010. However, that isn't my question. Instead, I'm wondering what benefits a web-based IDE might have? Assuming a company invests the time to create the missing features, what is the downside?

• Question about C# properties

  - by Impz0r

  Hey there, i bumped the other day into a little problem regarding C#'s properties. Let's say i do have this setup: public class Point { public float X; public float Y; } public class Control { protected Point m_Position = new Point(); public Position { get { return m_Position; } set { m_Position = value; } // reorganize internal structure.. reorganize(); } protected reorganize() { // do some stuff } } This is all fine, but when it comes to usage, i could write something like: Control myControl = new Control(); myControl.Position.X = 1.0f; The thing is, my Control class wont recognize that the Position has been changed because set hasn't been called. So i guess my question is, is there a way to make Control aware of any Position changes? Thanks in advance! Mfg Imp

• How to get a Javascript routine to NOT act if it's in a text box?

  - by talkingnews

  I've got a simple page, and in that page runs a simple jquery keypress routine to catch clicks of the numbers 1 to 9 (has to be that to pass RNIB accessibility test). And in that page is a form, which can have numbers entered as part of a postcode. http://find.talking-newspapers.co.uk/result.php?addressInput=kingston Scroll to the bottom, try typing 8 or 9 for example. The text is entered, but it also acts on the keypress. Expected, but not good. I'm aware of various things like document.getElementById, but I can't figure out how to put these together to ensure that while the cursor is in the text input box, it doesn't act out the keypress catcher.

• HA with nginx and cloud environment

  - by gotts

  I have a node in cloud environment which is used now as nginx and mongrels behind it. This is what nginx config looks like: upstream mongrel { server 127.0.0.1:8000; server 127.0.0.1:8001; server 127.0.0.1:8002; } I want to achieve the following: add another node nginx has to know about this new node automatically without stopping him, changing config(manually adding new node's mongrels) and starting it again. How can I make my load balancer(nginx) work in the way so it can be self-aware of nodes in cloud?

• Wrapping Multiple Elements (jQuery)

  - by Nimbuz

  I've this piece of HTML: div.content div.one content div.two content div.three content I want to add two divs on top and bottom and wrap one div around it so it becomes: div.top div.wrapper div.content div.one content div.two content div.three content div.bottom I'm aware of the several wrap selectors (innerWrap, wrapAll etc..) but I'm not sure how to wrap 2 divs. The following jQuery might work, but is there a better way to write it? $('content').wrap('<div class="wrapper"></div'); $('.wrapper').before('<div class="top"></div>'); $('.wrapper').after('<div class="bottom"></div>');

• how to selfhost wcf without iis

  - by dotnetcoder

  Reading up on WCF we have self hosting option available , one limitation here is we have to manage the host process lifecycle ourselves. What I am exploring here is to run the service without IIS and do a self hosting. Few things come to mind - How will request management work here. In case of IIS it manages the request and give control to dotnet on a particular thread. In absence of IIS do we need to write code ourselves to manage incoming requests ( say on a tcp port ) or WCF provides some classes to manage request and spawn threads to process each thread. I am aware that in case of self hosting this needs to be a windows service. In case of self hosting how can me tap on the number of simultaneous requests on the sever , it can be managed by limiting the thread pool ? or we can configure this via wcf ? Thanks dc

• Tool for response time analysis on JBoss server?

  - by Ariel Vardi

  I am running a pretty high traffic cluster of JBoss servers serving REST requests and I am interested in tools reading the access logs in Tomcat format (with %D parameter) to provide a detailed analysis of the response time on a per-call basis. Ideally this tool would generate a chart showing the progression of the response time throughout the day, hour per hour, then a weekly view with averages on the day, and monthly with average on the weeks (CACTI style). I've looked for such tools and couldn't find anything. Is any of you guys aware of something close to that before I start writing my own? I haven't looked into CACTI extensions yet, but that be an option?

• Objective C for Windows

  - by Luther Baker

  What would be the best way to write Objective-C on the Windows platform? Cygwin and gcc? Is there a way I can somehow integrate this into Visual Studio? Along those lines - are there any suggestions as to how to link in and use the Windows SDK for something like this. Its a different beast but I know I can write assembly and link in the Windows DLLs giving me accessibility to those calls but I don't know how to do this without googling and getting piecemeal directions. Is anyone aware of a good online or book resource to do or explain these kinds of things?

• Is it possible to transfer data between html pages driven by spring web flow?

  - by Easwaramoorthy Kanagaraj

  I am aware of passing data between jsp in spring web flow. Is it possible to transfer data between html pages driven by spring web flow. I don't want to use the HTML5 local storage capabilities. Example: Page 1: Search box for an employee id. Page 2: Search result for the employee details. Two ways that I could think: Get the employee details in page 1 by ajax and pass the result to the page two. Pass the employee id to page 2 and get the result by ajax in onload. In both case I need to pass any variable/data. I am confused in doing this. Is there anything in the Spring webflow using which I could do this? Thanks in advance, Easwar

• How do I control script execution time in PHP

  - by mathew

  for example I do have 5 PHP functions on a page which execute when loading. each functions has its own processing time and some of them take more time sometimes to complete the task. hence the total loading time of the said page is slow. my question is how do I control execution time for each script and set time limit for the same. I am aware that there is an in built function in PHP called set_time_limit(); but it gives fatal error if time is beyond the maximum limit...

• Ways not to write function headers twice?

  - by mee

  Hi, I've got a C/C++ question, can I reuse functions across different object files or projects without writing the function headers twice? (one for defining the function and one for declaring it) I don't know much about C/C++, Delphi and D. I assume that in Delphi or D, you would just write once what arguments a function takes and then you can use the function across diferent projects. And in C you need the function declaration in header files *again??, right?. Is there a good tool that will create header files from C sources? I've got one, but it's not preprocessor-aware and not very strict. And I've had some macro technique that worked rather bad. I'm looking for ways to program in C/C++ like described here http://www.digitalmars.com/d/1.0/pretod.html

• learning and "singing" Ruby with Sinatra

  - by microspino

  Hello I'm trying to improve my ruby knowledge by reading The Ruby Programming Language book. Reading Coders at work I saw that lot of the interviewees suggest to dive into a project source code to learn best practices to be aware of bad habits and of course to take new inspirations for how to do things. I decided to pick a project as more self contained as I could find. My choice was Sinatra since It's 1000 LOC. Is It a good project to learn? Do you suggest another one more simple (i.e. less LOCs)? I've tried to see rails machinery before but I came out scared from It.
