  • Vietnamese character in .NET Console Application (UTF-8)

    - by DucDigital
    Im trying to write down an UTF8 string (Vietnamese) into C# Console but no success. Im running on windows 7. I tried to use the Encoding class that convert string to char[] to byte[] and then to String, but no help, the string is input directly fron the database. Here is some example Tôi tên là Ð?c, cu?c s?ng th?t vui v? tuy?t v?i It does not show the special character like : Ð or ?... instead it show up ?, much worse with the Encoding class. Does anyone can try this out or know about this problem? Thank you My code static void Main(string[] args) { XDataContext _new = new XDataContext(); Console.OutputEncoding = Encoding.GetEncoding("UTF-8"); string srcString = _new.Posts.First().TITLE; Console.WriteLine(srcString); // Convert the UTF-16 encoded source string to UTF-8 and ASCII. byte[] utf8String = Encoding.UTF8.GetBytes(srcString); byte[] asciiString = Encoding.ASCII.GetBytes(srcString); // Write the UTF-8 and ASCII encoded byte arrays. Console.WriteLine("UTF-8 Bytes: {0}", BitConverter.ToString(utf8String)); Console.WriteLine("ASCII Bytes: {0}", BitConverter.ToString(asciiString)); // Convert UTF-8 and ASCII encoded bytes back to UTF-16 encoded // string and write. Console.WriteLine("UTF-8 Text : {0}", Encoding.UTF8.GetString(utf8String)); Console.WriteLine("ASCII Text : {0}", Encoding.ASCII.GetString(asciiString)); Console.WriteLine(Encoding.UTF8.GetString(utf8String)); Console.WriteLine(Encoding.ASCII.GetString(asciiString)); } and here is the outstanding output Nhà báo Ä‘i há»™i báo Xuân UTF-8 Bytes: 4E-68-C3-A0-20-62-C3-A1-6F-20-C4-91-69-20-68-E1-BB-99-69-20-62-C3- A1-6F-20-58-75-C3-A2-6E ASCII Bytes: 4E-68-3F-20-62-3F-6F-20-3F-69-20-68-3F-69-20-62-3F-6F-20-58-75-3F- 6E UTF-8 Text : Nhà báo Ä‘i há»™i báo Xuân ASCII Text : Nh? b?o ?i h?i b?o Xu?n Nhà báo Ä‘i há»™i báo Xuân Nh? b?o ?i h?i b?o Xu?n Press any key to continue . . .

  • PHP's apache_setenv function causes 500 Internal Server Error

    - by guitar-
    apache_setenv ( 'no-gzip', 1 ) I'm trying to disable gzip for a certain page's output, but only that page. This works fine on testing servers, but not the production server, which is running the same thing (CentOS and Apache), works on Ubuntu though. Anyway, do you know why? Or is there some other alternative? I was thinking of using ob_start () to put all output in a buffer, and then unzip it myself with a PHP function then call ob_end_flush ()... or would it not be gzipped until right before Apache sends it to the client? Thanks for any help.

  • Windows GUI application when user is not logged in?

    - by Tiax
    I've written a Autoit script that starts a GUI application, when the application starts there is a login form. The scripts fills the login form and tries to log in. Then it records the time it took to login to the application and shuts the application down afterwards, writes a output file with the time it took. The thing is, I can't get the application to start unless Im logged in as the user the Scheduled task is running on. So my question is: Is there any way to start a GUI application even though the user isn't logged in? Or is the only way to have a user always logged in?

  • Javascript not showing up on Facebook Application's Profile Tab

    - by prateekdayal
    Hi, This may sound very noobish but I have tried to read the forum posts and docs on javascript behavior on Facebook's profile tabs. I understand that profile tabs don't support referencing external javascript but even my inline tags are not showing up on profile pages. In fact I am trying the fbjs-swf bridge and the code needed to instantiate the swf does not show up on the page <fb:fbjs_bridge/> <div id="swfContainer"></div> <script> var swf = document.createElement('fb:swf'); swf.setId('my_swf_id'); swf.setWidth('630'); swf.setHeight('520'); swf.setSWFSrc('http://www.muziboo.com/swf/player4-2.swf'); document.getElementById('swfContainer').appendChild(swf); document.getElementById('my_swf_id').callSWF('asMethod', 'one', 'two'); </script> I see a swf embedded (the one for the fbjs bridge) but I don't see any script tag containing the above javascript code. What am I missing? I can see the javascript code on canvas page though Thanks

  • Why use Oracle Application Express for web app?

    - by Jack
    Hi all. I believe we're moving to Oracle Apex for future development. I've read about Oracle Apex on wikipedia and it's pro and con. It seem to me the con outweigh the pro but maybe I'm wrong. I get the sense that Oracle Apex is for DBA with little or no programing knowledge to setup a web app quickly sort like MS Access for none programmer. If you have Oracle Apex working experience, can you share your though? From wikipedia's entry, it doesn't seem like you need to know any programming language at all but just the PL/SQL? edit: Is Oracle Apex scalable? Can it handle traffic like Facebook's size? Thank. Jack

  • Creating database desktop application with data manipulation in Netbeans using Java Persistence

    - by Lulu
    It's my first time to use Persistence in developing a Java program because I usually connect via JDBC. I read that for large amounts of data, it is best to use persistence. I tried playing with the CRUD example of Netbeans. It's not very helpful thought because it only connects to the DB and allows addition and deletion of records. I need something that will allow me to manipulate the data like if the value from column C1 of table T1 is such, it will retrieve data from table t2. In short, I need to apply conditions before knowing what to retrieve exactly. The example in CRUD example already has a specific table to retrieve and only acts like a database manager. How is it possible to retrieve a specific item first then from this, will determine the next steps to be done. I'm also using embedded JavaDB/Derby as my database (also my first time to use because I usually use remote mysql)

  • Ajax Rich Internet Application framework for Linux + Firefox _AND_ iPhone consumption

    - by Maroloccio
    For a zero-budget (e.g. University) project we need to build a rich web UI for Firefox and iPhone clients. Firm requirement: all technologies to be free and open-source. Nice-to-have: all development to be done in Java/Eclipse. I generally like the Google's AppEngine + GWT combo but this project will require much more interactivity than what's in GWT 2.0. Something along the lines of: http://www.smartclient.com/smartgwt/showcase/. I know trusty plain ol' GWT won't cut it this time. Straight question: is there something that does the sort of thing that SmartGWT does and works really well on Safari/iPhone? I would say the mobile experience is even more important for this project than the desktop one. Optional question: perhaps this is not the best route to go at all? How could we otherwise render a rich UI with such capabilities and interactivity on both screen sizes? Windows, drag-and-drop, advanced tabs, dynamic grids... We don't need to support any other mobile devices. Yet. ;-)

  • Application Server or Lightweight Container?

    - by Jeff Storey
    Let me preface this by saying this is not an actual situation of mine but I'm asking this question more for my own knowledge and to get other people's inputs here. I've used both Spring and EJB3/JBoss, and for the smaller types of applications I've built, Spring (+Tomcat when needed) has been much simpler to use. However, when scaling up to larger applications that require things like load balancing and clustering, is Spring still a viable solution? Or is it time to turn to a solution like EJB3/JBoss when you start to get big enough to need that? I'm not sure if I've scoped the problem well enough to get a good answer, so please let me know. Thanks, Jeff

  • PHP DOMDocument Error Handling Problem

    - by Jon
    I'm having trouble trying to write an if statement for DOM that will check if $html is blank. However whenever the html page does end up blank, it just removes everything that would be below DOM (including what I had to check if it was blank). $html = file_get_contents("http://example.com/"); $dom = new DOMDocument; @$dom->loadHTML($html); $links = $dom->getElementById('dividhere')->getElementsByTagName('img'); foreach ($links as $link) { echo $link->getAttribute('src'); } All this does is grab an image url in the specified div, which works perfectly until the page is a blank html page. I've tried using SimpleHTMLDOM, which didn't work either (it didn't even fetch the image on working pages). Did I happen to miss something with this one or am I just missing something in both? include_once('simple_html_dom.php') $html = file_get_html("http://example.com/"); foreach($html->find('div[id="dividhere"]') as $div) { if(empty($div->src)) { continue; } echo $div->src; }

  • Should integration testing of DAOs be done in an application server?

    - by HDave
    I have a three tier application under development and am creating integration tests for DAOs in the persistence layer. When the application runs in Websphere or JBoss I expect to use the connection pooling and transaction manager of those application servers. When the application runs in Tomcat or Jetty, we'll be using C3P0 for pooling and Atomikos for transactions. Because of these different subsystems, should the DAO's be tested in a fully configured application server environment or should we handle those concerns when integration testing the service layer? Currently we plan on setting up a simple JDBC data source with non-JTA (i.e. resource-local) transactions for DAO integration testing, thus no application server is involved....but this leaves me wondering about environmental problems we won't uncover.
