  • Use a Datamodule in a Service Application

    - by O Engenheiro
    I wrote my Win32 App to test and debug. I've created a datamodule with all functionality needed to run the TCP sockets and IBDatabase components. After successfully testing the Datamodule in the Win32 application environment I am trying to hook the Datamodule into a Service Application template that I created, I can get nowhere in getting it to run. Could someone indicate whether this strategy of using a Datamodule with Component functionality encapsulating the primary service functions is workable and give a simple template example of how to hook it up if it is??

  • Rails: include index with fields_for form helper

    - by Patrick Oscity
    i'm trying to build two models from one form by using the fields_for method. my code looks like this: <% for scale in @event.scales %> <% f.fields_for "scale[]", scale do |scale_form| %> <p> Scale<br /> <%= scale_form.label :name %> <%= scale_form.text_field :name %> <%= scale_form.label :price %> <%= scale_form.text_field :price %> </p> <% end %> <% end %> but unfortunately the output html is missing the id's of the scales: <p> Scale<br /> <label for="event_scale__name">Name</label> <input id="event_scale__name" name="event[scale][][name]" size="30" type="text" /> <label for="event_scale__price">Price</label> <input id="event_scale__price" name="event[scale][][price]" size="30" type="text" /> </p> ... here's the corresponding controller and model: class EventsController < ApplicationController ... def new @event = Event.new @providers = Provider.find(:all, :order => :name) 3.times { @event.scales.build } respond_to do |format| format.html end end ... end class Event < ActiveRecord::Base has_many :scales ... end what am i doing wrong?

  • Reading JSON with Javascript/jQuery

    - by Josephine
    I'm building a game in javascript/html5 and I'm trying to build a database of locked doors in a maze that can be loaded from and overwritten to throughout gameplay. I've found a large number of tutorials online, but nothing is working. I was wondering if someone could look at what I'm trying and let me know what I'm doing wrong. My JSON file looks like this: { "doors": [ {"left":true, "right":false, "bottom":false}, {"left":false, "right":false, "bottom":false}, {"right":false, "bottom":false, "top":false}, {"left":false, "right":false, "top":false} ] } I want to build the HTML page so that when a player collides with a door it checks if its locked or not like: if (player.x < leftDoor.x + leftDoor.width && player.x + player.width > leftDoor.x && player.y < leftDoor.y + leftDoor.height && player.y + player.height > leftDoor.y) { if(doors[0].left == true) alert("door is locked"); else window.location = ( "2.html?p1="); } However I'm having trouble reading from the JSON file itself. I've tried things like: function loadJson() { $(document).ready(function() { $.getJSON('info.json', function(doors) { alert(doors[0].left); }); }); } But nothing happens, and I need to be able to access the information in the HTML as well. I'd rather use jQuery, but I'm not opposed to straight JS if it works. I've been trying to do this for ages and I'm getting absolutely no where. If someone could help that would be amazing. Thanks!

  • Possible to Dynamic Form Generation Using PHP global variables

    - by J M 4
    I am currently a fairly new programmer but am trying to build a registration page for a medical insurance idea we have which captures individual information and subsequent pieces of information about that individual's sub parts. In this case, it is a fight promoter enrolling his 15+ boxers for fight testing services. Right now, I have the site fully laid out to accept 7 fighters worth of information. This is collected during the manager's enrollment. However, each fighter's information is passed and stored in session super globals such as: $_SESSION['F1Firstname']; and $_SESSION['F3SSN3'];. The issue I am running into is this, I want to create a drop down menu selector for the manager to add information for up to 20-30 fighters. Right now I use PHP to state: if ($_SESSION['Num_Fighters'] 6) ... then display the table form fields to collect consumer data. If I have to build hidden elements for 30 fighters AND provide javascript/php validation (yes I am doing both) then I fear the file size for the document will be unnecessarily large for the maanger who only wants to enroll 2 fighters. Can anybody help?

  • Visual Studio Generating Code in Release mode

    - by bball
    I am using Visual Studio to compile some C++ Code. When I compile my program in Debug mode it works perfectly, but when I try compiling it in Release mode, VS halts when Generating Code (ie: took 20 mins and still didn't finish). After I forced VS to stop the build process, the executable generated was huge 2MB while it should be about 304KB. Please can you help figure this out. How should I setup the configuration parameters for Release mode to work? Thanks,

  • Java import statement

    - by nattyP
    I am using java on debian 5 java version "1.6.0_20" Java(TM) SE Runtime Environment (build 1.6.0_20-b02) Java HotSpot(TM) Client VM (build 16.3-b01, mixed mode, sharing) Why is there a difference between the following Case 1: import java.util.*; Case 2: import java.util.*; import java.util.Arrays; import java.util.List; Why doesnt the first case cover the second case? The code only compiles when I import Arrays and List explicitly. Code: import java.util.*; import java.util.Arrays; import java.util.List; public class Test { public static void main (String[] args) { List<Integer> i = new ArrayList(Arrays.asList(1,2,3,4,5,6,7,8,9,10)); List<Integer> j = new ArrayList(); ListIterator<Integer> n = i.listIterator(i.size()); while(n.hasPrevious()) { j.add(n.previous()); } println(j); } static void println(Object o) { System.out.println(o); } static void print(Object o) { System.out.print(o); } }

  • Listen to all Perforce commands made by my client machine to server

    - by Ed
    Hi, Is it possible to somehow listen to all perforce cammands issued from my machine to the perforce server? I did some googling yesterday and found a page somewhere about a perforce proxy or broker that would intercept perforce commands and allow you to do what you wanted with them before sending them to the server...and now can't find the page! I am trying to debug our build process (built using Maven) that is failing while running the maven-release-plugin (prepare). Cheers.

  • SAX parser does not resolve filename

    - by phantom-99w
    Another day, another strange error with SAX, Java, and friends. I need to iterate over a list of File objects and pass them to a SAX parser. However, the parser fails because of an IOException. However, the various File object methods confirm that the file does indeed exist. The output which I get: 11:53:57.838 [MainThread] DEBUG DefaultReactionFinder - C:\project\trunk\application\config\reactions\TestReactions.xml 11:53:57.841 [MainThread] ERROR DefaultReactionFinder - C:\project\trunk\application\config\reactions\null (The system cannot find the file specified) So the problem is obviously that null in the second line. I've tried nearly all variations of passing the file as a parameter to the parser, including as a String (both from getAbsolutePath() and entered by hand), as a URI and, even more weirdly, as a FileInputStream (for this I get the same error, except that the entire relative path gets reported as null, so C:\project\trunk\null). All that I can think of is that the SAXParserFactory is incorrectly configured. I have no idea what is wrong, though. Here is the code concerned: SAXParserFactory factory = SAXParserFactory.newInstance(); factory.setValidating(true); try { parser = factory.newSAXParser(); } catch (ParserConfigurationException e) { throw new InstantiationException("Error configuring an XML parser. Given error message: \"" + e.getMessage() + "\"."); } catch (SAXException e) { throw new InstantiationException("Error creating a SAX parser. Given error message: \"" + e.getMessage() + "\"."); } ... for (File f : fileLister.getFileList()) { logger.debug(f.getAbsolutePath()); try { parser.parse(f, new ReactionHandler(input)); //FileInputStream fs = new FileInputStream(f); //parser.parse(fs, new ReactionHandler(input)); //fs.close(); } catch (IOException e) { logger.error(e.getMessage()); throw new ReactionNotFoundException("An error occurred processing file \"" + f + "\"."); } ... } I have made no special provisions to provide a custom SAX parser implementation: I use the system default. Any help would be greatly appreciated!

  • Advanced All In One .NET Framework (should i go for a software factory ?)

    - by alfredo dobrekk
    Hi, i m starting a new project that would basically take input from user and save them to database among about 30 screens, and i would like to find a framework that will allow the maximum number of these features out of the box : .net c#. windows form. unit testing continuous integration logging screens with lists, combo boxes, text boxes, add, delete, save, cancel that are easy to update when you add a property to your classes or a field to your database. auto completion on controls to help user find its way use of an orm like nhibernate easy multithreading and display of wait screens for user easy undo redo tabbed child windows search forms ability to grant access to some functionnalities according to user profiles mvp/mvvm or whatever design patterns either some code generation from database to c# classe or generation of database schema from c# classes some kind of database versioning / upgrade to easily update database when i release patches to application once in production automatic control resizing code metrics analysis some code generator i can use against my entities that would generate some rough form i can rearrange after code documentation generator ... At this point i have 3 options : Build from scratch on top of clr :( Find functionnalities among several open source framework and use them as a stack for infrastucture Find a "software factory" I know its lot but i really would like to use existing code to build upon so i can focus on business rules. What open source tools would u use to achieve these ?

  • How do I find where an exception was thrown in C++?

    - by Alex
    I have a program that throws an uncaught exception somewhere. All I get is a report of an exception being thrown, and no information as to where it was thrown. It seems illogical for a program compiled to contain debug symbols not to notify me of where in my code an exception was generated. Is there any way to tell where my exceptions are coming from short of setting 'catch throw' in gdb and calling a backtrace for every single thrown exception?

  • How to get HABTM associated data using hasOne binding

    - by Moin
    Hi, I am following example documented at http://book.cakephp.org/view/83/hasAndBelongsToMany-HABTM I am trying to retrieve associated data using hasOne. I created 3 tables posts, tags and posts_tags. I wrote following code to debug Posts. $this->Post->bindModel(array( 'hasOne' => array( 'PostsTag', 'FilterTag' => array( 'className' => 'Tag', 'foreignKey' => false, 'conditions' => array('FilterTag.id = PostsTag.tag_id') )))); $output=$this->Post->find('all', array( 'fields' => array('Post.*') )); debug($output); I was expecting output something like below. Array ( 0 => Array { [Post] => Array ( [id] => 1 [title] => test post 1 ) [Tag] => Array ( [0] => Array ( [id] => 1 [name] => php ) [1] => Array ( [id] => 2 [name] => javascript ) [2] => Array ( [id] => 3 [name] => xml ) ) } But my output do not have Tags at all. Here is what I got. Array ( [0] => Array ( [Post] => Array ( [id] => 1 [title] => test post1 ) ) [1] => Array ( [Post] => Array ( [id] => 2 [title] => test post2 ) ) ) How do I get associated tags along with the post. I know I am missing something, but unable to figure out. Any help would be highly appreciated.

  • Exceptions not being caught

    - by Thomas Freudenberg
    We have following code: try { // some code throwing MyException } catch (MyException ex) { // [1] // no (re)throw here } catch (Exception ex) { if (ex is MyException) { // [2] } } If we run the code without a debugger attached, everything runs fine. However, IF we debug the code, we don't get to point [1] but [2]. As far as I understand the language specification this should not be possible. Even weirder, this code used run fine even while debugging. The strange behavior started only a few days ago.

  • how to insert into database from stored procedure in log4net?

  • .NET compact framework - where to put files so that they are accessible to emulator

    - by dominolog
    Hello I have a .NET CF project. In the project directory I put a simple xml file (users.xml) which has to be read by the device. When I debug the application on device emulator and try to load the file from code, the Exception is thrown (FileNotFoundException "Could not find file '\users.xml'."). Is there a mechanism to automatically deploy also configuration files to a device emulator?

  • Are there good reasons not to use an ORM?

    - by hangy
    During my apprenticeship, I have used NHibernate for some smaller projects which I mostly coded and designed on my own. Now, before starting some bigger project, the discussion arose how to design data access and whether or not to use an ORM layer. As I am still in my apprenticeship and still consider myself a beginner in enterprise programming, I did not really try to push in my opinion, which is that using an object relational mapper to the database can ease development quite a lot. The other coders in the development team are much more experienced than me, so I think I will just do what they say. :-) However, I do not completely understand two of the main reasons for not using NHibernate or a similar project: One can just build one’s own data access objects with SQL queries and copy those queries out of Microsoft SQL Server Management Studio. Debugging an ORM can be hard. So, of course I could just build my data access layer with a lot of SELECTs etc, but here I miss the advantage of automatic joins, lazy-loading proxy classes and a lower maintenance effort if a table gets a new column or a column gets renamed. (Updating numerous SELECT, INSERT and UPDATE queries vs. updating the mapping config and possibly refactoring the business classes and DTOs.) Also, using NHibernate you can run into unforeseen problems if you do not know the framework very well. That could be, for example, trusting the Table.hbm.xml where you set a string’s length to be automatically validated. However, I can also imagine similar bugs in a “simple” SqlConnection query based data access layer. Finally, are those arguments mentioned above really a good reason not to utilise an ORM for a non-trivial database based enterprise application? Are there probably other arguments they/I might have missed? (I should probably add that I think this is like the first “big” .NET/C# based application which will require teamwork. Good practices, which are seen as pretty normal on Stack Overflow, such as unit testing or continuous integration, are non-existing here up to now.)

  • Google Analytics version 3 - How to apply it correctly?

    - by ephramd
    I've added google analytics to my app with the intention of obtaining information about the screens you and send custom events. I am obtained duplicate content ...
