• Double value not correct on Device

  - by Clue

  int min = Int32.Parse(minutebox.Text); double kj = Convert.ToDouble(a.kj); double res = ((kj * op.koerpergewicht) * min); textbox.Text = res.ToString(); Shows me the correct number (with its punctuation - i. e. 2.33) on my English WP7-Emulator. However it doesn't work on my Device, which is set to German. The value is correct but the point, comma or whatever in that double value isn't shown correct. 43.22 on Emulator - 4322 on Device Why is that?

• Trouble using genericra to integrate activemq and glassfish when using failover protocol

  - by Kyle

  Hi, I'm attempting to use activemq in glassfish using the genericra resource adapter provided with glassfish 2.1. I have found a few pages with helpful information including http://activemq.apache.org/sjsas-with-genericjmsra.html. I have actually had success and been able to get MDBs to use activemq as their JMS provider, but I'm running into an issue as I'm trying to do some more complicated configuration. I want to set up a master-slave configuration, which would require my clients to use a brokerURL of failover:(tcp://broker1:61616,tcp://broker2:61616). In order to do this, I set the following property when calling asadmin create-resource-adapter-config (I have to escape '=' and ':'): ConnectionFactoryProperties=brokerURL\=failover\:(tcp\://127.0.0.1\:61616,tcp://127.0.0.1\:61617) However, I am now getting a StringIndexOutOfBoundsException when my application starts up. I suspect the comma in between the two URLs is the culprit, since this works fine: brokerURL\=failover\:(tcp\://127.0.0.1\:61616) Just wondering if anyone has dealt with this issue before. Also wondering if there is a better way to integrate with glassfish than using the generic resource adapter.

• WordPress Problem with enqueing a script

  - by casben79

  I am trying to enqueue a script from the functions.php file for a custom theme. here is the code I am using: wp_enqueue_script('innerfade','correct/path/to/innerfade.js', array('jquery'), '', false); I also tried to hardcode from the the functions file like so: ?> <script type='text/javascript' src="correct/path/to/innerfade.js"></script> <?php and both are outputting the following: correct/path/to/innerfade.js'?ver=2.9.2 so It doesnt seem to be a wp_enqueue_script problem What I cannot seem to figure is where the hell is the comma after the .js is coming from, it is causing a dead link hence not loading the script, anyone have any ideas??

• Server outputs the sourcecode of PHP page

  - by Akhilesh B Chandran

  I have a Shared Hosting package with HostGator. In it, I'm hosting around 4 websites. They are just some simple sites that doesn't likely to attract more visitors. But a few days ago, when I accessed one of my sites(via a browser), it outputted the PHP code of index.php, instead of outputting it as HTML. I think, at that time, the server was a bit busy or something. I heard that, Facebook also have got a similar condition where the home page's code was made available. So, how do I take preventive measures for this ? I always use phpBB forum's style of coding. That is, each sub pages, common functions, etc. are separated into subfolders. And in PHP, I would just include_once() or require_once() it. Also, these subfolders have a .htaccess file in which I have set the deny permission to the files inside it from outside. Also, in the main page(index), I would define a constant. And the first line of the subpages(which is situated in separate folders) is to check whether this constant is set. If not, calls die(). I am looking forward for solutions to this problem of outputting raw code when the page is accessed. Thanks in advance :)

• Data structure for bubble shooter game

  - by SundayMonday

  I'm starting to make a bubble shooter game for a mobile OS. Assume this is just the basic "three or more same-color bubbles that touch pop" and all bubbles that are separated from their group fall/pop. What data structures are common for storing the bubbles? I've considered using an undirected, connected graph where each node is a bubble. This seems like it could help answer the question "which bubbles (if any) should fall now?" after some arbitrary bubbles are popped and corresponding nodes are removed from the graph. I think the answer is all bubbles that were just disconnected from the graph should fall. However the graph approach might be overkill so I'm not sure. Another consideration for the data structure is collision detection. Perhaps being able to grab a list of neighboring bubbles in constant time for a particular "bubble slot" is useful. So the collision detection would be something like "moving bubble is closest to slot ij, neighbors of slot ij are bubbles a,b,c, moving bubble is sufficiently close to bubble b hence moving bubble should come to rest in slot ij". A game like this could be probably be made with a relatively crude grid structure as the primary data structure. However it seems like answering "which bubbles (if any) should fall now?" would be trickier with this data structure.

• Have problem understanding the id/name of java bean

  - by symfony

  In an XmlBeanFactory (including ApplicationContext variants), you use the id or name attributes to specify the bean id(s), and at least one id must be specified in one or both of these attributes. Does it mean the following are legal? <bean id="test"> <bean name="test"> But this is illegal: <bean non_idnorname="test"> you may also or instead specify one or more bean ids (separated by a comma (,) or semicolon (;) via the name attribute. Does it mean I can specify multiple ids this way: <bean name="id1;id2,id3"> Can someone convince my doubt?

• Excel validation range limits

  - by richardtallent

  When Excel saves a file, it attempts to combine identical Validation settings into a single rule with multiple ranges. This creates one of three issues, depending on the file type you choose to save: When saving as a standard Excel file (Office 2000 BIFF), a maximum of 1024 non-contiguous ranges that can have the same validation setting. When saving as a SpreadsheetML (Office 2002/2003 XML) file, you are limited to the number of non-contiguous ranges that can be represented, comma-delimited in R1C1 format, in 1024 characters. When saving as an Open Office XML (Office 2007 *.xlsx), there is a maximum of 511 non-contiguous ranges that can have the same validation setting. (I don't have Office 2007, I'm using the file converter for Office 2003). Once you bust any of these limits, the remaining ranges with the same Validation settings have their Validation settings wiped. For (1) and (3), Excel warns you that it can't save all of the formatting, but for (2) it does not.

• C - how to get fscanf() to determine whether what it read is only digits, and no characters

  - by hatorade

  Imagine I have a csv with and each value is an integer. so the first value is the INTEGER 100. I want fscanf() to read this line, and either tell me it's an integer ONLY, or not. So, it would pass 100 but fail on 100t. What i've been trying to get work is "%d," where the comma is the delimiter of my CSV. so the whole function is fscanf(fp, "%d,", &count) Unfortunately, this fails to fail on '100t,' works on '100' and works on 't'. so it just isn't distinguishing between 100 and 100t (all of these numbers are followed by commas, of course

• flex actionscript Datagridcolumn array

  - by Jad

  Hi, We have an AIR app and using a datagrid. We want to store the dataGrid.columns array in mySQL DB through PHP. This is needed because the user can customise the column headers of the datagrid and his preference needs to be stored and shown to him on his next login. Using HTTPService, we tried sending the dataGrid.columns array as a string, as follows, var ht:HTTPService = new HTTPService(); ht.url = Config.getServerURL(); ht.method = URLRequestMethod.POST; ht.resultFormat = "text"; ht.request["action"] = "updateGrid"; ht.request["headercolumns"] = colsArray.toString(); The data is stord as comma separated array string in DB. When we retrieve it back, cannot seem to cast it back to the DatagridColumns and assign it. Please let me know. Regards Jada.

• SEARCHING AND REPLACING BRACKETS IN A STRING IN ORACLE 10G

  - by Tunde

  hello, Thanks as usual for your prompt and kind suggestions. i am currently developing a function that is meant to execute dynamically created SQL statements. this is done by concatenating the columns and fetching them via cursors. the problem is that when there is a function with a comma between its arguments, the concat concatenates the contents of the functions inclusive. Is it possible to skip contents of every bracket found in a string using REGEXP_SUBTR or REGEXP_REPLACE? Many thanks for the anticipated response.

• mysql select query problem

  - by Chocho

  i have a form that has a multiple select drop down. a user can select more than one options in the select. the name of the select is array[]; using php i implode(",",$array) in mysql db, it stores the field as a text in this format "places"= "new york, toronto, london" when i want to display these fields i explode the commas. i am trying to run a report to display the places. here is my select: "select * from mytable where db.places .. userSelectedPlaces" how can i check toronto in lists of "places" that user selected? note "places" in the db might be either just "toronto" or it might be comma separated lists of places like "ny, toronto, london, paris, etc".

• Automated testing of a website for IE7 javascript errors?

  - by Andreas Bonini

  This week I decided to add a new element to a javascript array by copying a similar one from a previous line; unfortunately I forgot to remove the comma so the end result was something like var a = [1, 2, 3,]. The code went live late Friday afternoon just before everyone left for the week-end, and it completely broke everything in Internet Explorer 7 (and lower I assume) since it's such a great browser. Since there was no one to read emails (week-end) it went unnoticed for quite a while, and I really don't want something like this to happen again (especially in my code).. This is not the first of weird IE7 problems; I was wondering if there was a way to automatically test key pages looking for javascript or css errors, or really anything that IE8 would output in its new console in development tools. If there isn't, what do you usually do? You test the website after every change with all the browsers you support? (Something I'll do from now, at least for IE, if there is no way to run automated tests)

• Download lastfm tags into mp3 comment or genre tag

  - by Meng Tian

  for a long time I dream to have a songs lastfm tags in my music library, so I can use them to quickly generate playlists. There used to be a way to do that in amarok 1.4, but it never was stable. Than there is MusicBrainz Picard's lastfm/lastfmplus plugin. It is partially fine, but I cannot manage to make it look ONLY for the lastfm tags and put them into comments/genre/whatever but it always hast to tag everything. And it isn't particularly good with it, especially with small bands, songs without album etc. My music library is rather well organised. Most of the tags are correct. I also have quite some songs without an album. And I don't want it to find the albums for those songs, since it'd mess up my album view. So it must not touch the fields track name, track number, artist and album. All I want is that the most popular lastfm tags get into the genre or comments tag of the mp3, separated by semicolons, commas or whatever. I think I remember a script that did this job, but I cannot find. Does anybody know if there is anything like this? Would it be to hard to write this, for example as Banshee plugin? Thank you

• correct approach to store in database

  - by John

  I'm developing an online website (using Django and Mysql). I have a Tests table and User table. I have 50 tests within the table and each user completes them at their own pace. How do I store the status of the tests in my DB? One idea that came to my mind is to create an additional column in User table. That column containing testid's separated by comma or any other delimiter. userid | username | testscompleted 1 john 1, 5, 34 2 tom 1, 10, 23, 25 Another idea was to create a seperate table to store userid and testid. So, I'll have only 2 columns but thousands of rows (no of tests * no of users) and they will always continue to increase. userid | testid 1 1 1 5 2 1 1 34 2 10

• Pros and Cons of Different macro function / inline methods in C

  - by Robert S. Barnes

  According to the C FAQ, there are basically 3 practical methods for "inlining" code in C: #define MACRO(arg1, arg2) do { \ /* declarations */ \ stmt1; \ stmt2; \ /* ... */ \ } while(0) /* (no trailing ; ) */ or #define FUNC(arg1, arg2) (expr1, expr2, expr3) To clarify this one, the arguments are used in the expressions, and the comma operator returns the value of the last expression. or using the inline declaration which is supported as an extension to gcc and in the c99 standard. The do { ... } while (0) method is widely used in the Linux kernel, but I haven't encountered the other two methods very often if at all. I'm referring specifically to multi-statement "functions", not single statement ones like MAX or MIN. What are the pros and cons of each method, and why would you choose one over the other in various situations?

• Architecture of an action multiplayer game from scratch

  - by lcf

  Not sure whether it's a good place to ask (do point me to a better one if it's not), but since what we're developing is a game - here it goes. So this is a "real-time" action multiplayer game. I have familiarized myself with concepts like lag compensation, view interpolation, input prediction and pretty much everything that I need for this. I have also prepared a set of prototypes to confirm that I understood everything correctly. My question is about the situation when game engine must be rewind to the past to find out whether there was a "hit" (sometimes it may involve the whole 'recomputation' of the world from that moment in the past up to the present moment. I already have a piece of code that does it, but it's not as neat as I need it to be. The domain logic of the app (the physics of the game) must be separated from the presentation (render) and infrastructure tools (e.g. the remote server interaction specifics). How do I organize all this? :) Is there any worthy implementation with open sources I can take a look at? What I'm thinking is something like this: -> Render / User Input -> Game Engine (this is the so called service layer) -> Processing User Commands & Remote Server -> Domain (Physics) How would you add into this scheme the concept of "ticks" or "interactions" with the possibility to rewind and recalculate "the game"? Remember, I cannot change the Domain/Physics but only the Game Engine. Should I store an array of "World's States"? Should they be just some representations of the world, optimized for this purpose somehow (how?) or should they be actual instances of the world (i.e. including behavior and all that). Has anybody had similar experience? (never worked on a game before if that matters)

• How to manage and estimate unstructured requirements received from customers

  - by user20358

  A lot of the times I receive a software system's requirements from our customers in a very unstructured format. It is usually a bunch of "product development" guys from the customer's who come up with these "proposed solutions" to the business problems they have. While they are the experts at the business domain, a lot of the times they don't have the solutions right. This results in multiple versions of the same requirement mixing up of two requirements into one a few versions of the requirement later down the line, the requirements which were combined together get separated out again, each taking with it some of the new additions How do you work with such requirements coming in and sort them out into proper use cases and before development begins? What tools can we use to track a particular requirement's history, from the first time it was conceived till the time it gets crystallized into a proper use case? Estimating work against requirements received in such a fashion is a nightmare which ends up in making mistakes in understanding the requirement correctly and estimating the effort against it correctly. Any tips, tools, tricks to make this activity more manageable? I'm just trying to get some insights from someone more experienced than I am in requirements management and effort estimation.

• Oracle VM Virtualbox 4.0 extension packs

  - by wim.coekaerts

  Some people have asked what this new extension pack is in Oracle VM Virtualbox 4.0 and how it's different from 3.2 and earlier releases. The extension pack is a restructuring of how Oracle VM VirtualBox is installed. Please take a look at http://virtualbox.org and read up on what the product install looked like prior to 4.0, you'll see the following : There were 2 versions to download : - Oracle VM VirtualBox (open source edition) OSE - download of the source tarball with a GPL license + compile needed to run. - Oracle VM VirtualBox PUEL (personal use/eval license) - download of an installable binary with a number of additional non-gpl license drivers, usb2, sata, pxe boot for e1000, vrdp server etc., all built in to the install. This contained the OSE edition + additional drivers with the installer. Customers could purchase an enterprise software license for the latter version. To make it easier to build and release additional drivers, they have been separated out and are now installed through an "extension pack" starting with Oracle VirtualBox version 4. This extension pack is still licensed the same way as in every prior version, via a PUEL license or with the ability to purchase a commercial license. It is now also possible for other companies or users that want to add extensions to do so by creating a similar extension pack -- and there's no need to do a new release of the entire product to do so. So it's a more flexible structure for installing VirtualBox and drivers and allows for more modular additions. The source code of Oracle VM Virtualbox is, of course, still available just like in 3.x, for 4.0. Like 3.x, not for the additional drivers which are now in the extension pack.

• Get all related products based on their full-text search relationship

  - by MikeJ

  I have a Product table with the fields Id, Title, Description, Keywords (just comma separated list of keywords). Table is full-text indexed. When I view one product, I do a query and search the full-text catalog for any related products based on the Keywords field. select * from Products where Contains(Products.*, @keywordsFromOneProduct) Works like a charm. Now I would like to list all products and all their related products in a big list and I want to avoid calling this method for each item. Any ideas how could I do it? I was thinking about a job that would go through products one by one and build a one-many mapping table (fields ProductId, RelatedProductId), but I wonder is there a better way?

• How do I force apt-get to install a package that will not install due to a bug introduced by Ubuntu 11.10?

  Ubuntu 11.10 separated out python-profiler from the Python standard library due to licensing philosophies. (According to what I could Google, correct me if I'm wrong.) This is an active bug since October for 11.10. I have Python 2.7.2 installed, so the dependency errors are wrong. 'apt-get check' does not resolve the problem. What is the best way to resolve to this? Thank you. sudo apt-get install python-profiler Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming.

• IIS 7 - floats returning with commas instead of periods

  - by cc0

  I'm having trouble reading rows with float values, because these rows return for example 12,34 instead of 12.34 as it should. I suspect this is because both my IIS and SQL server is on a Norwegian Windows Server 2008. So I went to the regional settings and customized the default decimal symbol, then restarted my servers. The output in the database now shows the period decimal symbol, but when I request it through the IIS server it comes comma separated (the IIS server is on another computer, but that also has the default decimal symbol set to period). The IIS server is IIS7 and the SQL Server is 2008 Does anyone have any idea how to fix this? Any help would be greatly appreciated.

• Best way to implement keywords for image upload gallery

  - by Dan Berlyoung

  I'm starting to spec out an image gallery type system similar to Facebook's. Members of the site will be able to create image galleries and upload images for others to view. Images will have keywords the the uploader can specify. Here's the question, what's the best way to model this? With image and keyword tables linked vi a HABTM relation? Or a single image table with the keywords saved as comma delimited values in a text field in the image record? Then search them using a LIKE or FULL TEXT index function? I want to be able to pull up all images containing a given keyword as well as generate a keyword cloud. I'm leaning toward the HABTM setup but I wanted to see what everyone else though. Thanks!!

• Antenna Aligner Part 6: Little Robots

  - by Chris George

  A week ago I took temporary ownership of a HTC Desire S so that I could start testing my app under Android. Support for Android was not in my original plan, but when Nomad added support for it recently, I starting thinking why not! So with some trepidation, I clicked the Build for Android button on the Nomad toolbar... nothing. Hmm... that's not right, I was expecting something to build. After a bit of faffing around I finally realised that I hadn't read the text on the Android setup page properly (yes that's right, RTFM!), and I needed a two-part application identifier, separated by a dot. I did this (not sure what the two part thing is all about, that one my list to investigate!) After making the change, the Android build worked and created the apk file. I uploaded this to the device and nervously ran it... it worked!!!  Well, more or less! So, there was not splash screen, but this was no surprise because I only have the iOS icons and splash screen in my project at the moment. What was more concerning was the compass update didn't seem to be working. I suspect this is a result of using an iOS specific option in the Phonegap compass watcher. Another thing to investigate. I've also just noticed that the css gradient background hasn't worked either... These issues aside, it was actually more successful than I was expecting, so happy days! Right, lets get Googling...   Next time: Preparing for submission to the App Store! :-)

• ORM and component-based architecture

  - by EagleBeek

  I have joined an ongoing project, where the team calls their architecture "component-based". The lowest level is one big database. The data access (via ORM) and business layers are combined into various components, which are separated according to business logic. E.g., there's a component for handling bank accounts, one for generating invoices, etc. The higher levels of service contracts and presentation are irrelevant for the question, so I'll omit them here. From my point of view the separation of the data access layer into various components seems counterproductive, because it denies us the relational mapping capabilities of the ORM. E.g., when I want to query all invoices for one customer I have to identify the customer with the "customers" component and then make another call to the "invoices" component to get the invoices for this customer. My impression is that it would be better to leave the data access in one component and separate it from business logic, which may well be cut into various components. Does anybody have some advice? Have I overlooked something?
