  • How do I pass custom action data from a Visual Studio Setup MSI to an output project via a Merge mod

    - by Lex
    I have a fully working Setup project within Visual Studio 2008 that takes inputs from a UI and passes them via a Custom Action to the output - this works perfectly. Now I have to change this so that the UI is still in a setup project but that the output is within a merge module. The current Custom Action Data looks much like the following with EditHostUrl coming from a UI dialog editbox. /HostUrl="[EditHostUrl]" I now need to pass this value to the merge module and then from there use it as an input for the custom action data to the project output but there does not seem to be any documentation on how to achieve this. To be clear Wix/InstallShield etc... are not currently options. I would also rather not embed the UI within the merge module (for reasons of separation and also it's not supported out of the box with visual studio).

  • how can I add a new action to a controller?

    - by Angela
    I used the following in routes to add a new action to my Email controller: map.resources :emails, :member => { :newfwd => :put} The expected result was that newfwd_email_path(:id = 1) would generate the following urL: emails/1/newfwd It does. But I get an error, it treats '1' as an action and 'newfwd' as an id. I want '1' to be interpreted as the id for emails, upon which the newfwd action acts. I'm not sure what I'm doing wrong. (Note: I am using Rails 2.3.8)

  • Kohana 3 - How do I make the Default Route pass arguments to the Controller's Action?

    - by John Himmelman
    My controller action requires a parameter, but I can't get KO3's router to pass this parameter in the Default route. This sort of thing works with other routes. Here is an example to clarify... In bootstrap.php... Route::set('default', '(<controller>(/<action>(/<the_required_param>)))') ->defaults(array( 'controller' => 'DefaultController', 'action' => 'index', 'the_required_param' => 'some_default_value', )); In controller file... class DefaultController extends Controller { public function index($the_required_param) { echo 'value: ' . $the_required_param; } }

  • How do I execute an action in drupal after each time a node is saved?

    - by ford
    I'm developing an Action in Drupal which is supposed to activate after saving a node, exporting content to XML (which includes data from the node that was just saved), using the "Trigger: After saving an updated post" trigger. Unfortunately this action actually happens right before the information from the recently saved post is saved to the database. ie. when looking at the XML later, I find that the most recent change I made was not included. Saving after editing a different node will restore the previously missing data. How can I get my action to fire after the saving process is complete?

  • How do submit an object to a struts2 action using jQuery?

    - by James Drinkard
    I have an object that I'm populating from a selection off a table row that a user selects. I have a jQuery function that captures the click event and a hidden form field populates an id I need. However, I'm not sure as to the proper way to send off that object to a struts2 action? I tried using this: $(function() { $('#tbl tr').click(function() { var id = $(this).closest('tr').find('input:hidden').val(); var page = "<s:url action='update/deleteInfo.action'/>?model.isDelete=true&model.info.id=id"; console.log(page); window.location.href=(page); }); }); The model object has an isDelete boolean variable and the model has a nested info object that has an id variable with getter/setters. However, when I send this across, the model object isn't populated with these entries. Is there a way to do this or a better way than the url tag?

  • Learn Many Languages

    - by Jeff Foster
    My previous blog, Deliberate Practice, discussed the need for developers to “sharpen their pencil” continually, by setting aside time to learn how to tackle problems in different ways. However, the Sapir-Whorf hypothesis, a contested and somewhat-controversial concept from language theory, seems to hold reasonably true when applied to programming languages. It states that: “The structure of a language affects the ways in which its speakers conceptualize their world.” If you’re constrained by a single programming language, the one that dominates your day job, then you only have the tools of that language at your disposal to think about and solve a problem. For example, if you’ve only ever worked with Java, you would never think of passing a function to a method. A good developer needs to learn many languages. You may never deploy them in production, you may never ship code with them, but by learning a new language, you’ll have new ideas that will transfer to your current “day-job” language. With the abundant choices in programming languages, how does one choose which to learn? Alan Perlis sums it up best. “A language that doesn‘t affect the way you think about programming is not worth knowing“ With that in mind, here’s a selection of languages that I think are worth learning and that have certainly changed the way I think about tackling programming problems. Clojure Clojure is a Lisp-based language running on the Java Virtual Machine. The unique property of Lisp is homoiconicity, which means that a Lisp program is a Lisp data structure, and vice-versa. Since we can treat Lisp programs as Lisp data structures, we can write our code generation in the same style as our code. This gives Lisp a uniquely powerful macro system, and makes it ideal for implementing domain specific languages. Clojure also makes software transactional memory a first-class citizen, giving us a new approach to concurrency and dealing with the problems of shared state. Haskell Haskell is a strongly typed, functional programming language. Haskell’s type system is far richer than C# or Java, and allows us to push more of our application logic to compile-time safety. If it compiles, it usually works! Haskell is also a lazy language – we can work with infinite data structures. For example, in a board game we can generate the complete game tree, even if there are billions of possibilities, because the values are computed only as they are needed. Erlang Erlang is a functional language with a strong emphasis on reliability. Erlang’s approach to concurrency uses message passing instead of shared variables, with strong support from both the language itself and the virtual machine. Processes are extremely lightweight, and garbage collection doesn’t require all processes to be paused at the same time, making it feasible for a single program to use millions of processes at once, all without the mental overhead of managing shared state. The Benefits of Multilingualism By studying new languages, even if you won’t ever get the chance to use them in production, you will find yourself open to new ideas and ways of coding in your main language. For example, studying Haskell has taught me that you can do so much more with types and has changed my programming style in C#. A type represents some state a program should have, and a type should not be able to represent an invalid state. I often find myself refactoring methods like this… void SomeMethod(bool doThis, bool doThat) { if (!(doThis ^ doThat)) throw new ArgumentException(“At least one arg should be true”); if (doThis) DoThis(); if (doThat) DoThat(); } …into a type-based solution, like this: enum Action { DoThis, DoThat, Both }; void SomeMethod(Action action) { if (action == Action.DoThis || action == Action.Both) DoThis(); if (action == Action.DoThat || action == Action.Both) DoThat(); } At this point, I’ve removed the runtime exception in favor of a compile-time check. This is a trivial example, but is just one of many ideas that I’ve taken from one language and implemented in another.

  • How to fix an error in a Mercurial changeset comment?

    - by Sly
    Is there a way to rewrite the hg commit message if the wrong information was entered? We always include our Bug ID when we commit a changeset. For instance: hg commit -m "Bug 14585: LastName field should be mandatory" But If I put the wrong bug ID, is there a way (through an extension maybe) to fix the comment once the changeset has been committed and pushed to a central repo?

    - by Malcolm
    Obviously, I am a novice web designer. I'm using php and sql to do all the under-the-hood stuff, but I want a visually appealing as well as functional comment system. Right now I am just using HTML forms but they don't look very good. Should I be using javascript? Any tips to get me started?

  • How can I create a FreeBSD package using EPM that has the ORIGIN @comment?

    - by Chris R
    I'm building packages of our internal software products using EPM, and over time these packages (of which we have a large number) clutter up the output of pkg_delete and pkg_add with the following general kind of messages: err: pkg_add: package MYPACKAGE has no origin recorded I can see from some old FreeBSD lists that the +CONTENTS file in the package must have a line like this: @comment ORIGIN:some_source_path What I don't see is a way to get this line in place using EPM. Can somebody tell me how to do this?

  • What was the most refreshingly honest non-technical comment you saw?

    - by DVK
    OK, so we all saw the lists of "funny" or "bad" comments. However, today, when maintaining an old stored procedure, I stumbled upon a comment which I couldn't classify other than "refreshingly brutally honest", left by a previous maintainer around a really freakish (both performance and readability-wise) page-long query: -- Feel free to optimize this if you can understand what it means So, in the first (and hopefully only) poll type question in my history of Stack Overflow, I'd like to hear some other "refreshingly brutally honest" code comments you encountered or written.

  • ASP.NET Web API - Screencast series Part 2: Getting Data

    - by Jon Galloway
    We're continuing a six part series on ASP.NET Web API that accompanies the getting started screencast series. This is an introductory screencast series that walks through from File / New Project to some more advanced scenarios like Custom Validation and Authorization. The screencast videos are all short (3-5 minutes) and the sample code for the series is both available for download and browsable online. I did the screencasts, but the samples were written by the ASP.NET Web API team. In Part 1 we looked at what ASP.NET Web API is, why you'd care, did the File / New Project thing, and did some basic HTTP testing using browser F12 developer tools. This second screencast starts to build out the Comments example - a JSON API that's accessed via jQuery. This sample uses a simple in-memory repository. At this early stage, the GET /api/values/ just returns an IEnumerable<Comment>. In part 4 we'll add on paging and filtering, and it gets more interesting.   The get by id (e.g. GET /api/values/5) case is a little more interesting. The method just returns a Comment if the Comment ID is valid, but if it's not found we throw an HttpResponseException with the correct HTTP status code (HTTP 404 Not Found). This is an important thing to get - HTTP defines common response status codes, so there's no need to implement any custom messaging here - we tell the requestor that the resource the requested wasn't there.  public Comment GetComment(int id) { Comment comment; if (!repository.TryGet(id, out comment)) throw new HttpResponseException(HttpStatusCode.NotFound); return comment; } This is great because it's standard, and any client should know how to handle it. There's no need to invent custom messaging here, and we can talk to any client that understands HTTP - not just jQuery, and not just browsers. But it's crazy easy to consume an HTTP API that returns JSON via jQuery. The example uses Knockout to bind the JSON values to HTML elements, but the thing to notice is that calling into this /api/coments is really simple, and the return from the $.get() method is just JSON data, which is really easy to work with in JavaScript (since JSON stands for JavaScript Object Notation and is the native serialization format in Javascript). $(function() { $("#getComments").click(function () { // We're using a Knockout model. This clears out the existing comments. viewModel.comments([]); $.get('/api/comments', function (data) { // Update the Knockout model (and thus the UI) with the comments received back // from the Web API call. viewModel.comments(data); }); }); }); That's it! Easy, huh? In Part 3, we'll start modifying data on the server using POST and DELETE.

  • How to get data from struts2 action with jQuery?

    - by Rafa Romero
    I have an Struts2 Web with GoogleMaps. I want to load a list of markers which are saved in a SQL DDBB. To do this, I tried with jQuery and Ajax. Here you are the code: loadMarkers.java public class loadMarkers extends ActionSupport implements ServletRequestAware,ServletResponseAware{ //Variables de sesion/cookie FunctionClass ses; protected HttpServletResponse servletResponse; protected HttpServletRequest servletRequest; private String userID=""; //Variables del marker private List<marker> markersList = new ArrayList<marker>(); public String execute() throws Exception{ FunctionClass friends = new FunctionClass(); //Leemos de la cookie for(Cookie c : servletRequest.getCookies()) { if (c.getName().equals("userID")) userID = (c.getValue()); } System.out.println("en el loadMarkers"); connectionBBDD con = new connectionBBDD(); markersList = con.loadMarkers(userID); return SUCCESS; } I want to use the markerList array in Javascript, to create the markers. This is the struts.xml file: <package name="jsonActions" namespace="/test" extends="json-default"> <action name="LoadMarkers" class="web.localizadroid.maps.loadMarkers"> <interceptor-ref name="basicStack"/> <result type="json"> <param name="root">markersList</param> </result> </action> </package> And here you are the Javascript (jQuery) code: function loadMarkersJ(){ alert("dentro"); $.ajax({ type : "post", url : "LoadMarkers", dataType: "json", success : function(data) { alert(data); var image = new google.maps.MarkerImage ('http://i53.tinypic.com/ettquh.png'); var jSon_Object = eval("(" + data + ")"); //For para analizar los datos (Json) obtenidos de la BBDD for (x = 0; x < jSon_Object.length; x++) { var markersArray = []; var myLatlng = new google.maps.LatLng(jSon_Object[x].lat, jSon_Object[x].lon); markerLoaded = new google.maps.Marker( { position : myLatlng, map : map, icon: image, title: "NOMBRE: " + jSon_Object[x].tarjetName + "\n" + "ANOTACIONES: " + jSon_Object[x].anotaciones + "\n" + "TIME: " + jSon_Object[x].time }); markersArray.push(markerLoaded); if (markersArray) { for (i in markersArray) { alert("entro en forColocaMarkers"); if (markersArray[i].getAnimation() != null) { markersArray[i].setAnimation(null); } else { markersArray[i].setAnimation(google.maps.Animation.BOUNCE); } markersArray[i].setMap(map); } } } } }); } From success : function(data) { to the end, is JavaScript code to create de markers, and this it's OK. The problem is whith ajax, because I don't get to obtain markerList Array by jSon data return...I think that the problem is in the url attribute from $.ajax...I tried loadMarkers.action and loadMarkers, but nothing happens. When I execute the web, only prints the alert alert("dentro"), the alert alert(data) never has been printed. I have forgotten to add the code where I call the Javascript function (loadMarkersJ). Here you are: <p><s:a action="LoadMarkers.action" namespace="/test" onclick="loadMarkersJ(this)">Cargar Marcadores S</s:a></p> Somebody can help me please?

  • Refactoring routes - serving different layouts

    - by dmclark
    As a Rails NOOB, I started with a routes.rb of: ActionController::Routing::Routes.draw do |map| map.resources :events map.connect 'affiliates/list', :controller => "affiliates", :action => "list" map.connect 'affiliates/regenerate_thumb/:id', :controller => "affiliates", :action => "regenerate_thumb" map.connect 'affiliates/state/:id.:format', :controller => "affiliates", :action => "find_by_state" map.connect 'affiliates/getfeed', :controller => "affiliates", :action => "feed" map.resources :affiliates, :has_many => :events map.connect ":controller/:action" map.connect '', :controller => "affiliates" map.connect ":controller/:action/:id" map.connect ":controller/:action/:id/:format" end and i'm trying to tighten it up. and I've gotten as far as: ActionController::Routing::Routes.draw do |map| map.resources :events, :only => "index" map.resources :affiliates do |affiliates| affiliates.resources :has_many => :events affiliates.resources :collection => { :list => :get, :regenerate_thumb => "regenerate_thumb" } end # map.connect 'affiliates/regenerate_thumb/:id', :controller => "affiliates", :action => "regenerate_thumb" map.connect 'affiliates/state/:id.:format', :controller => "affiliates", :action => "find_by_state" map.connect 'affiliates/getfeed', :controller => "affiliates", :action => "feed" map.root :affiliates end what is confusing to me is routes vs parameters.. For example, I realized that the only difference between list and index is HOW it is rendered, rather than WHAT is rendered. Having a different action (as I do now) feels wrong but I can't figure out he right way. Thanks
