  • ASP.Net / MySQL : Translating content into several languages

    - by philwilks
    I have an ASP.Net website which uses a MySQL database for the back end. The website is an English e-commerce system, and we are looking at the possibility of translating it into about five other languages (French, Spanish etc). We will be getting human translators to perform the translation - we've looked at automated services but these aren't good enough. The static text on the site (e.g. headings, buttons etc) can easily be served up in multiple languages via .Net's built in localization features (resx files etc). The thing that I'm not so sure about it how best to store and retrieve the multi-language content in the database. For example, there is a products table that includes these fields... productId (int) categoryId (int) title (varchar) summary (varchar) description (text) features (text) The title, summary, description and features text would need to be available in all the different languages. Here are the two options that I've come up with... Create additional field for each language For example we could have titleEn, titleFr, titleEs etc for all the languages, and repeat this for all text columns. We would then adapt our code to use the appropriate field depending on the language selected. This feels a bit hacky, and also would lead to some very large tables. Also, if we wanted to add additional languages in the future it would be time consuming to add even more columns. Use a lookup table We could create a new table with the following format... textId | languageId | content ------------------------------- 10 | EN | Car 10 | FR | Voiture 10 | ES | Coche 11 | EN | Bike 11 | FR | Vélo We'd then adapt our products table to reference the appropriate textId for the title, summary, description and features instead of having the text stored in the product table. This seems much more elegant, but I can't think of a simple way of getting this data out of the database and onto the page without using complex SQL statements. Of course adding new languages in the future would be very simple compared to the previous option. I'd be very grateful for any suggestions about the best way to achieve this! Is there any "best practice" guidance out there? Has anyone done this before?

  • Using Oracle ADF Data Visualization Tools (DVT) Line Graphs to Display Weather Information

    - by Christian David Straub
    OverviewA guest post by Jeanne Waldman.I have a simple JDeveloper Fusion application that retrieves weather data. I wanted to compare the week's temperatures of different locations in a graph. I decided to check out the dvt:lineGraph component, and it took me a few minutes to add it to my jspx page and supply it with data.Drag and Drop the dvt:lineGraph onto your pageI opened my .jspx page in design modeIn the Component Palette, I selected ADF Data Visualization.Then I dragged 'Line' onto my page.A dialog popped up giving me options of the type of line graph. I chose the default.A lineGraph displayed with some default data. Hook up your weather dataNow I wanted to hook up my own data. I browsed the tagdoc, and I found the tabularData attribute.Attribute: tabularDataType: java.util.ListTagDoc:Specifies a list of data that the graph uses to create a grid and populate itself. The List consists of a three-member Object array for each data value to be passed to the graph. The members of each array must be organized as follows: The first member (index 0) is the column label, in the grid, of the data value. This is generally a String. If the graph has a time axis, then this should be a Java Date. Column labels typically identify groups in the graph. The second member (index 1) is the row label, in the grid, of the data value. This is generally a String. Row labels appear as series labels in the graph (usually in the legend). The third member (index 2) is the data value, which is usually a Double.The first member is the column label of the data value. This would be the day of the week.The second member is the row label of the data value. This would be the location name.The third member is the data value, usually a Double. This would be the temperature. I already had all this information, I just needed to put it in a List with a three-member Object array for each data value.   /**    * This is used for the lineGraph to show the data for each location.    */   public List<Object[]> getTabularData()   {      List<Object[]> tabularData = new ArrayList<Object []>();      List<WeatherForecast> weatherForecastList = getWeatherForecastList();      // loop through the list and build up the tabular data. Then cache it.      for(WeatherForecast wf : weatherForecastList)      {        List<ForecastDay> forecastDayList = wf.getForecastDayList();        String location = wf.getLocation();        for (ForecastDay fday : forecastDayList)        {          String day = fday.getPrettyDate();          String highTemp = fday.getHighF();          tabularData.add(new Object[]{day, location, Double.valueOf(highTemp)});        }             }      return tabularData;    }  Now I bound the lineGraph to this method by setting tabularData to#{weatherForAllLocationsBean.tabularData}weatherForAllLocationsBean is my bean that is defined in faces-config.xml. Adding a barGraphIn about 30 seconds, I added a barGraph with the same data. I dragged and dropped a bar graph onto the page, used the same tabularData as I did in the line graph. The page looks like this:  ConclusionI was very happy how fast it was to hook up my weather data to these graphs. They look great, and they have built in functionality. For instance, I can hide/show a location by clicking on the name of the location in the legend.

  • Take Control Of Web Control ClientID Values in ASP.NET 4.0

    Each server-side Web control in an ASP.NET Web Forms application has an ID property that identifies the Web control and is name by which the Web control is accessed in the code-behind class. When rendered into HTML, the Web control turns its server-side ID value into a client-side id attribute. Ideally, there would be a one-to-one correspondence between the value of the server-side ID property and the generated client-side id, but in reality things aren't so simple. By default, the rendered client-side id is formed by taking the Web control's ID property and prefixed it with the ID properties of its naming containers. In short, a Web control with an ID of txtName can get rendered into an HTML element with a client-side id like ctl00_MainContent_txtName. This default translation from the server-side ID property value to the rendered client-side id attribute can introduce challenges when trying to access an HTML element via JavaScript, which is typically done by id, as the page developer building the web page and writing the JavaScript does not know what the id value of the rendered Web control will be at design time. (The client-side id value can be determined at runtime via the Web control's ClientID property.) ASP.NET 4.0 affords page developers much greater flexibility in how Web controls render their ID property into a client-side id. This article starts with an explanation as to why and how ASP.NET translates the server-side ID value into the client-side id value and then shows how to take control of this process using ASP.NET 4.0.

  • As a game developer, which data structure use for develop the game? [duplicate]

    - by Rizwanabbasi
    This question already has an answer here: When should vector/list be used? 5 answers We are developing a game for bank robbery. The game plots a bank robbery. Lots of people witness that robbery. Our game will load the lists of suspected offenders while the players (witnesses) will have to identify the offenders of this robbery. Game should load list of offenders to identify the one as quickly as possible. Admin can add/remove offenders in the lists and two or more lists of offenders can also be merged into one (to show it to the player). As a game developer, which data structure we should use for develop the game? Justify your selection with solid arguments. Remember the most critical requirement is that the list should load super fast.

  • Is using MultiMaps code smell? If so what alternative data structures fit my needs?

    - by Pureferret
    I'm trying to model nWoD characters for a roleplaying game in a character builder program. The crux is I want to support saving too and loading from yaml documents. One aspect of the character's is their set of skills. Skills are split between exactly three 'types': Mental, Physical, and Social. Each type has a list of skills under if. My Yaml looks like this: PHYSICAL: Athletics: 0 Brawl: 3 MENTAL: Academics: 2 Computers My initial thought was to use a Multimap of some sort, and have the skill type as an Enum, and key to my map. Each Skill is an element in the collection that backs the multimap. However, I've been struggling to get the yaml to work. On explaining this to a colleague outside of work they said this was probably a sign of code smell, and he's never seen it used 'well'. Are multiMaps really code smell? If so what alternate data structures would suit my goals?

  • How to find data usage of a user on my website?

    - by Dharmik
    I have a website (project) where users get logged in, do their work and then they log out. I need to build a report that displays how much each person has used of data. (bandwidth, how much was downloaded in Kb, etc) So the process may be like counting start of usage from user login to user logout. I have seen a little about Webalizer and AWStats for something like this, But I am not sure how they work. I have tried Content-Length but some pages don't send content-length.I have also seen mod_bandwidth but still I am little confused. This process is needed for my site because now, our company is thinking of charging per usage and also bandwidth allocation for each users (according to their membership). I haven't worked with this type of tools, I am newbie in this matter. I have done only simple websites not any setting like this in Apache or Linux. My project is in Codeigniter.

  • Configuration data: single-row table vs. name-value-pair table

    - by Heinzi
    Let's say you write an application that can be configured by the user. For storing this "configuration data" into a database, two patterns are commonly used. The single-row table CompanyName | StartFullScreen | RefreshSeconds | ... ---------------+-------------------+------------------+-------- ACME Inc. | true | 20 | ... The name-value-pair table ConfigOption | Value -----------------+------------- CompanyName | ACME Inc. StartFullScreen | true (or 1, or Y, ...) RefreshSeconds | 20 ... | ... I've seen both options in the wild, and both have obvious advantages and disadvantages, for example: The single-row tables limits the number of configuration options you can have (since the number of columns in a row is usually limited). Every additional configuration option requires a DB schema change. In a name-value-pair table everything is "stringly typed" (you have to encode/decode your Boolean/Date/etc. parameters). (many more) Is there some consensus within the development community about which option is preferable?

  • Rails Easy Data Dumping

    - by Madhan ayyasamy
    Hi Friends,The following useful snippets,you can find out the easiest way of ruby on rails environment data dumping. You’ll often need to get data from production to dev or dev to your local or your local to another developer’s local. One plug-in we use over and over is Yaml_db. This nifty little plug-in enables you to dump or load data by issuing a Rake command. The data is persisted in a yaml file located in db/data.yml. This is very portable and easy to read if you need to examine the data.01rake db:data:dump02 03example data found in db/data.yml04 05---06campaigns:07  columns:08  - id09  - client_id10  - name11  - created_at12  - updated_at13  - token14  records:15  - - "1"16    - "1"17    - First push18    - 2008-11-03 18:23:5319    - 2008-11-03 18:23:5320    - 3f2523f6a66521  - - "2"22    - "2"23    - First push24    - 2008-11-03 18:26:5725    - 2008-11-03 18:26:5726    - 9ee8bc427d94

  • Coarse Collision Detection in highly dynamic environment

    - by Millianz
    I'm currently working a 3D space game with A LOT of dynamic objects that are all moving (there is pretty much no static environment). I have the collision detection and resolution working just fine, but I am now trying to optimize the collision detection (which is currently O(N^2) -- linear search). I thought about multiple options, a bounding volume hierarchy, a Binary Spatial Partitioning tree, an Octree or a Grid. I however need some help with deciding what's best for my situation. A grid seems unfeasible simply due to the space requirements and cache coherence problems. Since everything is so dynamic however, it seems to be that trees aren't ideal either, since they would have to be completely rebuilt every frame. I must admit I never implemented a physics engine that required spatial partitioning, do I indeed need to rebuild the tree every frame (assuming that everything is constantly moving) or can I update the trees after integrating? Advice is much appreciated - to give some more background: You're flying a space ship in an asteroid field, and there are lots and lots of asteroids and some enemy ships, all of which shoot bullets. EDIT: I came across the "Sweep an Prune" algorithm, which seems like the right thing for my purposes. It appears like the right mixture of fast building of the data structures involved and detailed enough partitioning. This is the best resource I can find: http://www.codercorner.com/SAP.pdf If anyone has any suggestions whether or not I'm going in the right direction, please let me know.

  • Transmitting Form Data from the Client to the Web Server

    The steps involved in transmitting form data from the client to the web server User loads web form User enters data in to web form fields User clicks submit On submit page validates fields using JavaScript. If validation errors are found then the validation script stops the browser from canceling posting the data to the web server and displays error messages as needed If the form passes the data validation process then the browser will URL encode the values of every field and post it to the server.  The server reads the posted data from the query string and then again validates the data just to ensure data consistency and to prevent any non-validated data because JavaScript was turned off on the clients browser from being inserted in to a database or passed on to other process If the data passes the second validation check then the server side code will continue with the requested processes

  • How-to get the binding for a tab in the Dynamic Tab Shell Template

    - by Frank Nimphius
    The Dynamic Tab Shell template does expose a method on the Tab.java class that allows you to get access to the ADF binding container for a tab. At least in theory this works, because in practice this call always returns a null value (a bug is filed for this). To work around the problem, you can use code similar to the following to get the ADF binding for a specific tab DCBindingContainer currentBinding = (DCBindingContainer) BindingContext.getCurrent().getCurrentBindingsEntry(); DCBindingContainer templateBinding = (DCBindingContainer)currentBinding.get("ptb1"); DCBindingContainer tabBinding= (DCBindingContainer)templateBinding.get("r"+0);  In the code line above, the tabBinding variable will hold the binding reference to the first tab in the dynamic tab shell template. Note that the tab doesn't need to be visible for this (which has to do with how the template works).  "ptb1" is the template reference name in the PageDef file (Executable section) of the template consumer view. Check this string in your page before using this code. If it differs, change it also in the code above. "r0" is the binding reference of the first tab in the template. Te last tab is referenced by "r14".

  • Fun Upgrading to .Net 4.0

    - by Sam Abraham
    We are currently in the process of upgrading one of our applications to .Net 4.0. Aside from us geeks wanting to always use latest and greatest technologies, an immediate business need for Silverlight 4.0 features justified our upgrade endeavor. The following is a summary of some issues we ran into with our web project:   For security purposes, the IIS 7 .Net 4.0 ISAPI filter is disabled. “Allow” it from the ISAPI and CGI Restrictions screen as shown:   Figure 1 - Allowing ASP.Net 4.0 ISAPI Filter   By default the Web Setup Project only requires the .Net Framework 4 Client Profile to be installed on target system, which offers a lighter weight install for client machines consuming .Net 4.0 applications. However, using certain .Net 4.0 features requires the full .Net 4.0 Framework as outlined in this link: http://msdn.microsoft.com/en-us/library/cc656912.aspx. We hence needed to update the installer to require the complete .Net 4.0 Framework on the target machine and to prompt for its installation if needed.   To accomplish this goal, we updated the installer’s launch conditions to check for .Net 4.0 as well as the installer prerequisites as shown:     Figure 2- Ensure Web Setup Project runs on full .Net 4.0 version Figure 3 - Launch Conditions screen Figure 4 - Set launch condition to .Net 4.0.

  • Looking into the jQuery LazyLoad Plugin

    - by nikolaosk
    I have been using JQuery for a couple of years now and it has helped me to solve many problems on the client side of web development.  You can find all my posts about JQuery in this link. In this post I will be providing you with a hands-on example on the JQuery LazyLoad Plugin.If you want you can have a look at this post, where I describe the JQuery Cycle Plugin.You can find another post of mine talking about the JQuery Carousel Lite Plugin here. Another post of mine regarding the JQuery Image Zoom Plugin can be found here. You can have a look at the JQuery Overlays Plugin here . There are times when when I am asked to create a very long page with lots of images.My first thought is to enable paging on the proposed page. Imagine that we have 60 images on a page. There are performance concerns when we have so many images on a page. Paging can solve that problem if I am allowed to place only 5 images on a page.Sometimes the customer does not like the idea of the paging.Believe it or not some people find the idea of paging not attractive at all.In that case I need a way to only load the initial set of images and as the user scrolls down the page to load the rest.So as someone scrolls down new requests are made to the server and more images are fetched. I can accomplish that with the jQuery LazyLoad Plugin.This is just a plugin that delays loading of images in long web pages.The images that are outside of the viewport (visible part of web page) won't be loaded before the user scrolls to them. Using jQuery LazyLoad Plugin on long web pages containing many large images makes the page load faster. In this hands-on example I will be using Expression Web 4.0.This application is not a free application. You can use any HTML editor you like. You can use Visual Studio 2012 Express edition. You can download it here.  You can download this plugin from this link. I launch Expression Web 4.0 and then I type the following HTML markup (I am using HTML 5)<!DOCTYPE html><html lang="en">  <head>    <title>Liverpool Legends</title>    <script type="text/javascript" src="jquery-1.8.3.min.js"></script>        <script type="text/javascript" src="jquery.lazyload.min.js" ></script></head>  <body>    <header>                <h1>Liverpool Legends</h1>    </header>        <div id="main">             <img src="barnes.JPG" width="800" height="1100" /><p />        <img src="dalglish.JPG" width="800" height="1100" /><p />                <img class="LiverpoolImage" src="loader.gif" data-original="fans.JPG" width="1200" height="900" /><p />        <img class="LiverpoolImage" src="loader.gif" data-original="lfc.JPG" width="1000" height="700" /><p />        <img class="LiverpoolImage" src="loader.gif" data-original="Liverpool-players.JPG" width="1100" height="900" /><p />        <img class="LiverpoolImage" src="loader.gif" data-original="steven_gerrard.JPG" width="1110" height="1000" /><p />        <img class="LiverpoolImage" src="loader.gif" data-original="robbie.JPG" width="1200" height="1000" /><p />          </div>            <footer>        <p>All Rights Reserved</p>      </footer>                    <script type="text/javascript">                $(function () {                    $("img.LiverpoolImage").lazyload();                });        </script>     </body>  </html> This is a very simple markup. I have  added references to the JQuery library (current version is 1.8.3) and the JQuery LazyLoad Plugin. Firstly, I add two images         <img src="barnes.JPG" width="800" height="1100" /><p />        <img src="dalglish.JPG" width="800" height="1100" /><p />  that will load immediately as soon as the page loads. Then I add the images that will not load unless they become active in the viewport. I have all my img tags pointing the src attribute towards a placeholder image. I’m using a blank 1×1 px grey image,loader.gif.The five images that will load as the user scrolls down the page follow.         <img class="LiverpoolImage" src="loader.gif" data-original="fans.JPG" width="1200" height="900" /><p />        <img class="LiverpoolImage" src="loader.gif" data-original="lfc.JPG" width="1000" height="700" /><p />        <img class="LiverpoolImage" src="loader.gif" data-original="Liverpool-players.JPG" width="1100" height="900" /><p />        <img class="LiverpoolImage" src="loader.gif" data-original="steven_gerrard.JPG" width="1110" height="1000" /><p />        <img class="LiverpoolImage" src="loader.gif" data-original="robbie.JPG" width="1200" height="1000" /><p /> Then we need to rename the image src to point towards the proper image placeholder. The full image URL goes into the data-original attribute.The Javascript code that makes it all happen follows. We need to make a call to the JQuery LazyLoad Plugin. We add the script just before we close the body element.         <script type="text/javascript">                $(function () {                    $("img.LiverpoolImage").lazyload();                });        </script>We can change the code above to incorporate some effects.          <script type="text/javascript">  $("img.LiverpoolImage").lazyload({    effect: "fadeIn"  });    </script> That is all I need to write to achieve lazy loading. It it true that you can do so much with less!!I view my simple page in Internet Explorer 10 and it works as expected. I have tested this simple solution in all major browsers and it works fine. You can test it yourself and see the results in your favorite browser. Hope it helps!!!

  • Dynamic Monitoring Service (DMS) Configuration Dumping and CPU Utilization

    - by ShawnBailey
    There was recently a report of CPU spikes on a system that were occuring at precise 3 hour intervals. Research revealed that the spikes were the result of the Dynamic Monitoring Service generating a metrics dump and writing it under the server 'logs' folder for every WLS server in the domain. This blog provides some information on what this is for and how to control it. The Dynamic Monitoring Service is a facility in FMw (JRF to be more precise) that collects runtime data on the components deployed to WebLogic. Each component is responsible for how much or how little they use the service and SOA collects a fair amount of information. To view what is collected on any running server you can use the following URL, http://host:port/dms/Spy and login with admin credentials. DMS is essentially always running and collecting this information in the runtime and to protect against loss of this data it also runs automatic backups, by default at the 3 hour interval mentioned above. Most of the management options for DMS are exposed through WLST but these settings are not so we must open the dms_config.xml file which can be found in DOMAIN_HOME/config/fmwconfig/servers/<server_name>/dms_config.xml. The contents are fairly short and at the bottom you will find the following entry: <dumpConfiguration>     <dump intervalSeconds="10800" maxSizeMBytes="75" enabled="true"/> </dumpConfiguration> The interval of 10800 seconds corresponds to the 3 hours and the maximum size is 75MB. The file is written as an archive to DOMAIN_HOME/servers/<server_name>/logs/metrics. This archive contains the dump in XML format. You can disable the dumps all together by simply setting the 'enabled' value to 'false' or of course you could modify the other parameters to suit your needs. Disabling the dumps will NOT impact DMS collections or display at runtime. It will only eliminate these periodic backups.
