  • Blackberry XML Parsing Application not working

    - by Nirmal
    Hello All... I found one sample application from the Blackberry knowledgebase. From that application I have put that sample application on my eclipse plugin, and the code is as follows : import javax.microedition.io.*; import net.rim.device.api.ui.*; import net.rim.device.api.ui.component.*; import net.rim.device.api.ui.container.*; import net.rim.device.api.system.*; import net.rim.device.api.xml.parsers.*; import org.w3c.dom.*; import org.xml.sax.*; class XML_Parsing_Sample extends UiApplication { // creating a member variable for the MainScreen MainScreen _screen = new MainScreen(); // string variables to store the values of the XML document String _node, _element; Connection _connectionthread; public static void main(String arg[]) { XML_Parsing_Sample application = new XML_Parsing_Sample(); // create a new instance of the application // and start the application on the event thread application.enterEventDispatcher(); } public XML_Parsing_Sample() { _screen.setTitle("XML Parsing");// setting title _screen.add(new RichTextField("Requesting.....")); _screen.add(new SeparatorField()); pushScreen(_screen); // creating a screen // creating a connection thread to run in the background _connectionthread = new Connection(); _connectionthread.start();// starting the thread operation } public void updateField(String node, String element) { // receiving the parsed node and its value from the thread // and updating it here // so it can be displayed on the screen String title = "My App"; _screen.add(new RichTextField(node + " : " + element)); if (node.equals(title)) { _screen.add(new SeparatorField()); } } private class Connection extends Thread { public Connection() { super(); } public void run() { // define variables later used for parsing Document doc; StreamConnection conn; try { // providing the location of the XML file, // your address might be different conn = (StreamConnection) Connector .open("http://www.sufalamtech.com/demo/moviewebservice/Test.xml"); // next few lines creates variables to open a // stream, parse it, collect XML data and // extract the data which is required. // In this case they are elements, // node and the values of an element DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory .newInstance(); DocumentBuilder docBuilder = docBuilderFactory .newDocumentBuilder(); docBuilder.isValidating(); doc = docBuilder.parse(conn.openInputStream()); doc.getDocumentElement().normalize(); NodeList list = doc.getElementsByTagName("*"); _node = new String(); _element = new String(); // this "for" loop is used to parse through the // XML document and extract all elements and their // value, so they can be displayed on the device for (int i = 0; i < list.getLength(); i++) { Node value = list.item(i).getChildNodes().item(0); _node = list.item(i).getNodeName(); _element = value.getNodeValue(); updateField(_node, _element); }// end for }// end try // will catch any exception thrown by the XML parser catch (Exception e) { Dialog.alert("exception = " + e); } }// end connection function }// end connection class }// end XML_Parsing_Sample But when I am running this application, the simulator just showing me a Blank screen with label Requesting... Anybody help me out for this ? Thanks in advance...

  • Validate dependent model validation and show error message.

    - by piemesons
    Just taking a simple example. We have a question on stackoverflow and while posting a question we want to validate title_of_question, description_of_question that they should be present. Now we have a another model tag having habtm relationshio with question model. How to validate that while saving the question. Means question must have some tags. here the code:-- Models:-- class Question < ActiveRecord::Base belongs_to :user has_and_belongs_to_many :tags has_many :comments, :as => :commentable has_many :answers, :dependent => :destroy validates_presence_of :title, :content, :user_id end class Tag < ActiveRecord::Base has_and_belongs_to_many :questions validates_presence_of :tag end Form for entering question and tag <div class="form"> <% form_for :question ,@question, :url => {:action => "create" } do |f| %> <fieldset> <%= f.error_messages %> <legend>Post a question</legend> <div> <%= f.label :title %>: <%= f.text_field :title, :size => 100 %> </div> <div> <%= f.label :content ,'Question' %>: <%= f.text_area :content, :rows => 10, :cols => 100 %> </div> <div> <%= label_tag 'tags' %>: <%= text_field_tag 'tag' ,'',:size=> 60 %> add multiple tag using comma </div> <div> <%= submit_tag "Post question" %> </div> </fieldset> <% end %> </div> From Controller.. (Right now question will be saved without validating tag) def create @question = Question.new(params[:question]) @question.user_id=session[:user_id] if @question.save flash[:notice] = "Question has been posted." redirect_to question_index_path else render :action => "new" end end questions_tags table has been created. One approach is creating a virtual column using attribute accessors. another approach is validate associated. right now assuming new tags can be created.(but not duplicate).

  • Behaviour of insertion trigger when defining autoincrement in Oracle

    - by Genba
    I have been looking for a way to define an autoincrement data type in Oracle and have found these questions on Stack Overflow: Autoincrement in Oracle Autoincrement Primary key in Oracle database The way to use autoincrement types consists in defining a sequence and a trigger to make insertion transparent, where the insertion trigger looks so: create trigger mytable_trg before insert on mytable for each row when (new.id is null) begin select myseq.nextval into :new.id from dual; end; I have some doubts about the behaviour of this trigger: What does this trigger do when the supplied value of "id" is different from NULL? What does the colon before "new" mean? I want the trigger to insert the new row with the next value of the sequence as ID whatever the supplied value of "new.id" is. I imagine that the WHEN statement makes the trigger to only insert the new row if the supplied ID is NULL (and it will not insert, or will fail, otherwise). Could I just remove the WHEN statement in order for the trigger to always insert using the next value of the sequence?

  • Comet VS Ajax polling

    - by xRobot
    I need to create a chat like facebook chat. With Comet I need more memory to keep the connection. With Ajax polling there is a latency problem if I send request every 3-4 seconds. So... If the latency ( 3-4 seconds ) doesn't matter, Is Ajax Polling better for my case ?

    - by Vanchinathan
    Hi All, We have a requirement at my workplace to automate the webservice testing. We have been using QTP scripts to do so. We as a team, Kind of leaning towards Jbehave as a choice. Is JBehave a good choice for web service functional testing automation? We do use Soap UI to test manually. But we are planning to automate the functional and regression testing to reduce the release cycle time. Suggestions welcome.

  • Mootools accordion inside another...

    - by jimbo
    Hi all, This is a funny one... I have created a mootools accordion with tabs, each section appears when clicked. This works fine. Now within the first accordion that shows, I have another accordion that displays more data. This was to keep the area small with the mass of information that is needed on the page. All works fine, the problem come when the information hidden is larger than the area that is worked our for the first tabs accordion, and it wont display. does any-one either understand what i'm trying to say, or have an idea of a fix or workaround? Hope this makes sense!

  • Add Reference to a WCF Service Executable

    - by Sphynx
    I have 3 projects in my solution. 1 - client, 2 - server, 3 - WCF service library. Server executable exposes the service provided in the library. I need to add a reference to it, rather than to the library directly. When I open "Add Service Reference" and click "Discover", it only lists the library data, and doesn't list the executable server option. How do I reference a WCF executable service, so the client code would be generated automatically? I use VS 2010. Thanks for your help.

  • Documentation style: how do you differentiate variable names from the rest of the text within a comm

    - by Alix
    Hi, This is a quite superfluous and uninteresting question, I'm afraid, but I always wonder about this. When you're commenting code with inline comments (as opposed to comments that will appear in the generated documentation) and the name of a variable appears in the comment, how do you differentiate it from normal text? E.g.: // Try to parse type. parsedType = tryParse(type); In the comment, "type" is the name of the variable. Do you mark it in any way to signify that it's a symbol and not just part of the comment's text? I've seen things like this: // Try to parse "type". // Try to parse 'type'. // Try to parse *type*. // Try to parse <type>. // Try to parse [type]. And also: // Try to parse variable type. (I don't think the last one is very helpful; it's a bit confusing; you could think "variable" is an adjective there) Do you have any preference? I find that I need to use some kind of marker; otherwise the comments are sometimes ambiguous, or at least force you to reread them when you realise a particular word in the comment was actually the name of a variable. (In comments that will appear in the documentation I use the appropriate tags for the generator, of course: @code, <code></code>, etc) Thanks!

  • ASP.NET MVC Authentication Cookie Not Being Retrieved

    - by Jamie Wright
    I am having a hard time implementing "Remember Me" functionality in an MVC application with a custom principal. I have boiled it down to ASP.NET not retrieving the authentication cookie for me. I have included a snaphot below from Google Chrome. Shows the results of Request.Cookies that is set within the controller action and placed in ViewData for the view to read. Notice that it is missing the .ASPXAUTH cookie Shows the results from the Chrome developer tools. You can see that .ASPXAUTH is included here. Does anyone know what the issue may be here? Why does ASP.NET not read this value from the cookie collection?

  • Queue access to the database to avoid multiple cache items

    - by MikeJ
    I have a music related ASP.NET web site which caches a lot of static information from the database on the first request. Sometimes, the application is reset and cache is cleared while the application is on heavy load and then all http requests go to the database to retrieve that static data and cache it for other requests. How can I ensure that only one request go to the database and cache the results, so that other request simply read that info from cache and not needlessly retrieve the same info over and over again. Can I use thread locking? For example, can I do something like lock(this) { db access here }?

  • Array help needed for unit conversion application

Here's the code i made so far. The project is about arrays. Any help appreciated.

  • Attach file to mail using php

    - by ktsixit
    Hi all, I've created a form which contains an upload field file and some other text fields. I'm using php to send the form's data via email and attach the file. This is the code I'm using but it's not working properly.

  • Why can't I retrieve UIDeviceOrientation correctly while playing a movie in MPMoviePlayerController?

    - by Zelldweller
    Everything works fine while I'm not playing anything (I'm calling beginnotifications, etc, and using the orientation to rotate my view). But after I start playing with MPMoviePlayerController every time I try a... UIDeviceOrientation orientation = [[UIDevice currentDevice] orientation]; ...orientation gets a UIDeviceOrientationUnknown. Any clue? When the movie stops everything works alright again. I need this orientation to rotate the player's window, because Im using Iphone OS 3.1 so I can't directly use the view property inside MPMovie player controller.

  • MSBuild OutputPath property and absolute paths

    - by Frederik Vig
    I'm trying to set the OutputPath value to an absolute path: <OutputPath>c:\Projects\xxx\Deployment</OutputPath> But I get this error: Error 17 The expression "[System.IO.Path]::GetFullPath(D:\Projects\xxx\trunk\xxx.Web.Deployment\c:\Projects\xxx\Deployment\)" cannot be evaluated. The given path's format is not supported. 1 1 xxx.Web.Deployment Is there a way to use an absolute path with the OutputPath property? I've tried experimenting with the BaseOutputPath property: <PropertyGroup Condition="'$(Configuration)|$(Platform)' == 'Deployment|AnyCPU'"> <BaseOutputPath>C:\Projects\xxx\</BaseOutputPath> <OutputPath>.\Deployment</OutputPath> <EnableUpdateable>true</EnableUpdateable> <UseMerge>true</UseMerge> <SingleAssemblyName>xxx.Web.Deployment</SingleAssemblyName> But it seems to get ignored. What are BaseOutputPath and BaseIntermediateOutputPath used for?
