• RESTful services and update operations

  - by Igor Brejc

  I know REST is meant to be resource-oriented, which roughly translates to CRUD operations on these resources using standard HTTP methods. But what I just wanted to update a part of a resource? For example, let's say I have Payment resource and I wanted to mark its status as "paid". I don't want to POST the whole Payment object through HTTP (sometimes I don't even have all the data). What would be the RESTful way of doing this? I've seen that Twitter uses the following approach for updating Twitter statuses: http://api.twitter.com/1/statuses/update.xml?status=playing with cURL and the Twitter API Is this approach in "the spirit" of REST? UPDATE: PUT - POST Some links I found in the meantime: PUT or POST: The REST of the Story PUT is not UPDATE PATCH Method for HTTP

• Does Hibernate's GenericGenerator cause update and saveOrUpdate to always insert instead of update?

  - by Derek Mahar

  When using GenericGenerator to generate unique identifiers, do Hibernate session methods update() and saveOrUpdate() always insert instead of update table rows, even when the given object has an existing identifier (where the identifier is also the table primary key)? Is this the correct behaviour? public class User { private String id; private String name; public User(String id, String name) { this.id = id; this.name = name; } @GenericGenerator(name="generator", strategy="guid")@Id @GeneratedValue(generator="generator") @Column(name="USER_ID", unique=true, nullable=false) public String getId() { return this.id; } public void setId(String id) { this.id = id; } @Column(name="USER_NAME", nullable=false, length=20) public String getUserName() { return this.userName; } public void setUserName(String userName) { this.userName = userName; } } class UserDao extends AbstractDaoHibernate { public void updateUser(final User user) { HibernateTemplate ht = getHibernateTemplate(); ht.saveOrUpdate(user); } }

• Model Binding using ASP.NET MVC, getting datainput to the controller.

  - by Calibre2010

  Pretty Basic one here guys. I have a View which holds 2 textfields for input and a submit button <%using (Html.BeginForm("DateRetrival", "Home", FormMethod.Post)){ %> <%=Html.TextBox("sday")%> <%=Html.TextBox("eday")%> <input type="submit" value="ok" id="run"/> <% }%> the following controller action which I want to bind the data input is as follows [AcceptVerbs(HttpVerbs.Get)] public ActionResult DateRetrival() { return View(); } [AcceptVerbs(HttpVerbs.Post)] public ActionResult DateRetrival(string submit) { return null; } When I debug this and look in the action methods parameter, the value is null. When I've entered values in both textboxes and and clicked the submit method.

• Code editor with autocomplete

  - by Andrey

  I need to create a code editor for my own simple language: className.MethodName(parameterName = 2, ... ) I've created the appropriate grammar and autogenerate parser using ANTLR tool. Now I would like to have an autocomplete for class, method, variables and parameter names. This list should be context dependent, f.e. for "class." it should display methods and for "class.Method(" - parameters. I was going to parse the text and display the list depending on in which node the cursor is. The problem is that for incomplete code like "aaa.bbb(" the parser produces an error instead of a syntax tree. Any idea how to solve this problem? Maybe I'm on the wrong way and I shouldn't parse code to display autocomplete?

• LINQ to SQL repository - caching data

  - by creativeincode

  I have built my first MVC solution and used the repository pattern for retrieving/inserting/updating my database. I am now in the process of refactoring and I've noticed that a lot of (in fact all) the methods within my repository are hitting the database everytime. This seems overkill and what I'd ideally like is to do is 'cache' the main data object e.g. 'GetAllAdverts' from the database and to then query against this cached object for things like 'FindAdvert(id), AddAdvert(), DeleteAdvert() etc..' I'd also need to consider updating/deleting/adding records to this cache object and the database. What is the best apporoach for something like this? My knowledge of this type of things is minimal and really looking for advice/guidance/tutorial to point me in the right direction. Thanks in advance.

• SMS Gateway Devices

  - by u07ch

  Can anyone recommend a good SMS Gateway device that sends and receives messages and has a reasonable API. We are looking for a hardware device that a Sim Card and works with Windows / .Net. I am working with about 50 different countries (Right now 50 will only become more in the future) and dealing with that many SMS suppliers and their various methods for billing and sending / responding to messages is proving unmanageable. It may be much easier to have a single method and call it by country. We do bulk send messages but from the logs this is at most 500 messages at a time (though it could be up-to about 1500 at a time) - mostly its small numbers far less than 500 messages. Ideally would like to get message delivery data and error handling type messages back from the device. I am not interested in a hosted solution unless it has the ability to receive a message to a local number in EVERY country.

• XSD data set with Oracle database

  - by Ed Woodcock

  Hi folks, I'm having a major issue with an XSD dataset mapping thingy that I'm using within my current project. We are using XSDs for some data abstraction (it's quicker and debatably more maintainable that using Parameterised SQL or a StoredProc), and on my machine (running in the VS development environment) thy're working fine. However, on the Pre-production server we use for our testing, the XSDs are not working correctly: some method calls will fail with the following error: System.ArgumentException: Value does not fall within the expected range. at Oracle.DataAccess.Client.OracleParameter.set_DbType(DbType value) Has anyone ever encountered this issue before? The methods being called are simple select statements using 1-3 parameters, and as I said before they work fine on my machine.

• How to dynamically replace a method implementation in ObjC2?

  - by Abhi

  I am trying to learn how to write plugins using SIMBL. I got my plugin to load with the target application, and also know the method that I wish to override. However, I am not able to use class_getInstanceMethod correctly based on snippets on the Internet. Have things changed in OSX 10.6 and/or ObjC2? The following code from culater.net gives "Dereferencing pointer to incomplete type" on the second-last statement: BOOL DTRenameSelector(Class _class, SEL _oldSelector, SEL _newSelector) { Method method = nil; // First, look for the methods method = class_getInstanceMethod(_class, _oldSelector); if (method == nil) return NO; method->method_name = _newSelector; return YES; } Is there a complete example of how to override a method using SIMBL plugins? Thanks!

• ASP.NET MVC: What's the difference in concept between Service and Repository

  - by Richard77

  Hello, The question I'm asking is kind of subjective. I've seen twice, while exercising with real projects such as StoreFront, both Repository and Services. Sometimes they can just be folders or projects attached to the solution. But they contain classes and interfaces. So, I'd like to know what goes to the repository and what goes to the services. So far, I was familiar with repositories (we put methods and properties in the repository to reduce the complexity in the controller). How about the services? So, ASP.NET MVC: What's the difference in concept between Service and Repository? (Maybe none) My question is Kind of subjective, but I'd like to make sure that I'm not missing anything. Thanks for helping

• calling webservice in java servlet

  - by Pravin

  I have created a servlet which displays a form having some fields and a submit button and also created a web service having methods which are needed in my servlet. I have deployed the web service on Tomcat 5.5.9/Axis and servlet web application on Tomcat ( same instance of Tomcat) using eclipse. Since one is web service and other is web application both are running on separate instances of tomcat, so when i run them separately i.e servlet without the call to web service and a client that access that webservice it works fine but when i integrate them both i get a error like exception: javax.servlet.ServletException I would like to call the web service and return the result when i press the button Please advice me on how to implement that.

• How to control Time zone formatting in System.Xml.Serialization or during application execution?

  - by Beal

  I'm developing a C# .Net Application that is executing on a system located in the Central Time Zone. The application gets information from a third party using an API they provide. I have used the WSDL to produce the code that my application access the API with...their reporting API allows you to define a start date and end date for the report. These are C# DateTime fields and XSD:dateTime. Now when I set the start date and end dates and allow the API to create the SOAP messages the dates don't always include a Time Zone unless I set the date fields using the ToLocalTime method; however, the method will create the DateTime fields in the Central Time Zone (CST) but I need to have it create these fields in the Pacific Time Zone (PST). If I set my machine time to PST all is good...but of course that causes other time issues. What methods can I use to control the formatting of the DateTime? Alternatively, is there a application setting that can be set in C# that allows timezone control?

• how to disable web page cache throughout the servlets

  - by Kurt

  To no-cache web page, in the java controller servlet, I did somthing like this in a method: public ModelAndView home(HttpServletRequest request, HttpServletResponse response) throws Exception { ModelAndView mav = new ModelAndView(ViewConstants.MV_MAIN_HOME); mav.addObject("testing", "Test this string"); mav.addObject(request); response.setHeader("Cache-Control", "no-cache, no-store"); response.setHeader("Pragma", "no-cache"); response.setDateHeader("Expires", 0); return mav; } But this only works for a particular response object. I have many similar methods in a servlet. And I have many servlets too. If I want to disable cache throughout the application, what should I do? (I do not want to add above code for every single response object) Thanks in advance.

• How do I improve the efficiency of the queries executed by this generic Linq-to-SQL data access clas

  - by Lee D

  Hi all, I have a class which provides generic access to LINQ to SQL entities, for example: class LinqProvider<T> //where T is a L2S entity class { DataContext context; public virtual IEnumerable<T> GetAll() { return context.GetTable<T>(); } public virtual T Single(Func<T, bool> condition) { return context.GetTable<T>().SingleOrDefault(condition); } } From the front end, both of these methods appear to work as you would expect. However, when I run a trace in SQL profiler, the Single method is executing what amounts to a SELECT * FROM [Table], and then returning the single entity that meets the given condition. Obviously this is inefficient, and is being caused by GetTable() returning all rows. My question is, how do I get the query executed by the Single() method to take the form SELECT * FROM [Table] WHERE [condition], rather than selecting all rows then filtering out all but one? Is it possible in this context? Any help appreciated, Lee

• Print out PDF with javascript [closed]

  - by Daniel Abrahamsson

  I have a need to print out multiple PDFs with the help of javascript. Is this even possible without rendering each PDF in a separate window and calling window.print()? Basically, I would like to be able to do something like print('my_pdf_url'). Edit After some searching, I have come to the conclusion that there are no other methods than the one I've described above. It is a far from perfect solution, but it works in simple cases. Edit I ended up merging the PDFs to a monster PDF on the server side and then send this single PDF to the user, who can then choose to print it out.

• VB.NET overloading array access?

  - by Wayne Werner

  Hi, Is it possible to overload the array/dict access operators in VB.net? For example, you can state something like: Dim mydict As New Hashtable() mydict.add("Cool guy", "Overloading is dangerous!") mydict("Cool guy") = "Overloading is cool!" And that works just fine. But what I would like to do is be able to say: mydict("Cool guy") = "3" and then have 3 automagically converted to the Integer 3. I mean, sure I can have a private member mydict.coolguy and have setCoolguy() and getCoolguy() methods, but I would prefer to be able to write it the former way if at all possible. Thanks

• Android Image Getter for Larger Images

  - by y ramesh rao

  I have used all the Standard Network related code for Getting Images of about 45KB to 75KB but all are failing these methods work fine for Files of about 3-5KB size of Images. How can I achieve Downloading Image of 45 - 75KB for displaying them on an ImageView in Android for my Netowrk Operations the Things I have used are final URL url = new URL(urlString); final URLConnection conn = url.openConnection(); HttpURLConnection httpConn = (HttpURLConnection) conn; httpConn.setAllowUserInteraction(true); httpConn.setInstanceFollowRedirects(true); httpConn.setRequestMethod("GET"); httpConn.connect(); and the Second option that I have had used is:: DefaultHttpClient httpClient = new DefaultHttpClient(); HttpGet getRequest = new HttpGet(urlString); HttpResponse response = httpClient.execute(getRequest); why is this code functional for Smaller Sized Images and not for Larger Size Images. ?

• Building a subquery with ARel in Rails3

  - by Christopher

  I am trying to build this query in ARel: SELECT FLOOR(AVG(num)) FROM ( SELECT COUNT(attendees.id) AS num, meetings.club_id FROM `meetings` INNER JOIN `attendees` ON `attendees`.`meeting_id` = `meetings`.`id` WHERE (`meetings`.club_id = 1) GROUP BY meetings.id) tmp GROUP BY tmp.club_id It returns the average number of attendees per meeting, per club. (a club has many meetings and a meeting has many attendees) So far I have (declared in class Club < ActiveRecord::Base): num_attendees = meetings.select("COUNT(attendees.id) AS num").joins(:attendees).group('meetings.id') Arel::Table.new('tmp', self.class.arel_engine).from(num_attendees).project('FLOOR(AVG(num))').group('tmp.club_id').to_sql but, I am getting the error: undefined method `visit_ActiveRecord_Relation' for #<Arel::Visitors::MySQL:0x9b42180> The documentation for generating non trivial ARel queries is a bit hard to come by. I have been using http://rdoc.info/github/rails/arel/master/frames Am I approaching this incorrectly? Or am I a few methods away from a solution?

• Anyone got Twitter xAuth working with the Compact Framework yet?

  - by peSHIr

  This question is related to a number of other questions on oAuth on the Compact Framework (one, two) but seems slightly more specific to me, as it specifically involves getting Twitters xAuth API call (meant for non web applications to be able to do oAuth) working on the Compact Framework. Are SSL HTTP connections and the encryption methods needed for xAuth needed part of Compact Framework 3.5? Did anyone get the Twitter xAuth working on Windows Mobile already? If so, what libraries did you use for this? Any tips are welcome.

• What does ruby include when it encounters the "include module" statement?

  - by Steve Weet

  If I have the following project structure project/ lib/ subproject/ a.rb b.rb lib.rb where lib.rb looks like this :- module subproject def foo do_some_stuff end end and a.rb and b.rb both need to mixin some methods within lib.rb and are both namespaced within a module like so :- require 'subproject/lib' module subproject class A include Subproject def initialize() foo() end end end What does ruby do when it encounters the include statement? How does it know that I want to only include the mixin from lib.rb rather than the whole module which includes both class A and class B, is this based purely on the require of subproject/lib or am I getting it wrong and it is including the whole of the module, including the definitions of Class A and B within themselves?

• What 'best practices' exist for handing enum heirarchies?

  - by FerretallicA

  I'm curious as to any solutions out there for addressing enum heirarchies. I'm working through some docs on Entity Framework 4 and trying to apply it to a simple inventory tracking program. The possible types for inventory to fall into are as follows: INVENTORY ITEM TYPES: Hardware PC Desktop Server Laptop Accessory Input (keyboards, scanners etc) Output (monitors, printers etc) Storage (USB sticks, tape drives etc) Communication (network cards, routers etc) Software What recommendations are there for handling enums in a situation like this? Are enums even the solution? I don't really want to have a ridiculously normalised database for such a relatively simple experiment (eg tables for InventoryType, InventorySubtype, InventoryTypeToSubtype etc). I don't really want to over-complicate my data model with each subtype being inherited even though no additional properties or methods are included (except PC types which would ideally have associated accessories and software but that's probably out of scope here). It feels like there should be a really simple, elegant solution to this but I can't put my finger on it. Any assistance or input appreciated!

• How to get equivalent of ResultSetMetaData without ResultSet

  - by javanix

  Hey Guys - I need to resolve a bunch of column names to column indexes (so as to use some of the nice ResultSetMetaData methods). However, the only way that I know how to get a ResultSetMetaData object is by calling getMetaData() on some ResultSet. The problem I have with that is that grabbing a ResultSet takes up uneccesary resources in my mind - I don't really need to query the data in the table, I just want some information about the table. Does anyone know of any way to get a RSMD object without getting a ResultSet (from a potentially huge table) first? Thanks!

• JSON in an AJAX request

  - by Josh K

  I have a PHP API I'm working with that outputs everything as JSON. I need to call one of the API methods and parse it out using an AJAX request. I am using jQuery (though it shouldn't matter). When I make the request it errors out with a "parsererror" as the textStatus and a "Syntax Error: invalid label" when I make the request. Simplified code: $.ajax ({ type: "POST", url: "http://mydomain.com/api/get/userlist/"+mid, dataType: "json", dataFilter: function(data, type) { /* Here we assume and pray */ users = eval(data); alert(users[1].id); }, success: function(data, textStatus, XMLHttpRequest) { alert(data.length); // Should be an array, yet is undefined. }, error: function(XMLHttpRequest, textStatus, errorThrown) { alert(textStatus); alert(errorThrown); }, complete: function(XMLHttpRequest, textStatus) { alert("Done"); } });

• Equivalent of describeType for Flex Component EVENTS

  - by Joshua

  Using "introspection" In Flex I can say: var classInfo:XML=describeType(SomeObject); Which will list for me the Accessors, Methods And Variables. (http://livedocs.adobe.com/flex/3/html/help.html?content=usingas_8.html) But what is the equivalent to programmatically inspect all of an object's possible EVENTS? (NOT JUST the events for which event listeners have been set, but to somehow step through a list of all VALID EVENTS for which event listeners may POTENTIALLY be set -- I realize that such lists are readily available online, and that's great for cases when I know the object's type at design type, but I require some way to inspect any given displayobject programmatically at runtime, and determine what events, if any, are or may be associated with it.)

• Visual Studio Editor, MEF in-Depth

  - by NewProgrammer

  I have been having difficulty simply writing a Visual Studio Editor Extension with MEF (Managed Extensiblity Framework). I thank those who answered my previous question, as they helped me know that I need to work with MEF. I've been trying to learn MEF for the Visual Studio Editor from MSDN's page, Extending the Editor, but it appears that I have a hard time understanding it. Can anyone provide strong resource or tutorials in addressing problem such as using the right ContentTypeDefintion (IGlyphFactory, TextMarkTag, etc...), and what is a ITagger. I need to understand these things, as most of the walkthrough only extending the text, such as only using the "spans" functionality, while I need to use "selection" methods and use MouseEventHandlers. Does anyone know an example similiar to my example, or references can tell me something about MEF's for VS editor in-depth?
