  I am a beginner in Android programming. I want to build a simple application with a main list view in the screen and two buttons at the bottom of the screen. When more items are added to the list view, the list view should scroll without increasing the overall length of the list view.

• Code generator tool to generate a property and backing field

  - by MattSlay

  I'm working in VS2008 and C#, and I'm looking for a (free) code generator tool to generate a property with getter and setter, as well as the backing private field to go with. The template thingy in VS does not make the field to go with it. Just looking for something a little bit better. I once saw a web site where you could build this code, then cust-and-paste it from the web page to your code.

• Building a custom textbox in GTK

  - by CommuSoft

  I want to make my own GTK# Textbox, the textbox should draw the text and it's cursor on a special way. However keyboard and mouse-handling is quite complex and is also influenced by for instance the operating system (for instance the use of dead keys) Is there a way to build such a control without having to worry about keyboard input? I assume I have to make a textbox control that inherits the original textbox control. How can I handle drawing requests and mouse movements?

• Override default javascript functionality with jQuery

  - by deth4uall

  I am trying to overwrite a JavaScript on change event in the below code with jQuery however I believe that the inline JavaScript is taking priority over the jQuery functionality declared. Essentially I am trying to have an AJAX version of my site which includes an additional JavaScript file. I need this functionality to still work without the additional AJAX version, but I am not sure as to whether I should include it in the main JavaScript file or leave it inline like it is right now. Any suggestions and information regarding them would be greatly appreciated! Thanks! <form action="/cityhall/villages/" method="post" name="submit_village"> <select name="village" onchange="document.submit_village.submit();"> <option value=""></option> </select> </form> I am trying to use the jQuery Form Plugin to submit the posts to the PHP to handle the requests as follows: var bank_load_options = { target: '#content', beforeSubmit: showRequest, success: showResponse }; $('form.get_pages').livequery(function(){ $(this).ajaxForm(bank_load_options); return false; }); I modified the code as following: <form action="/cityhall/villages/" method="post" id="submit_village" name="submit_village"> <select name="village" class="get_pages" rel="submit_village"> <option value=""></option> </select> </form> <script> # main JavaScript $('.get_pages').live('change',function(e){ var submit_page = $(this).attr('rel'); $("#"+submit_page).submit(); }); # ajax JavaScript var bank_load_options = { target: '#content', beforeSubmit: showRequest, success: showResponse }; $('.get_pages').live('change',function(){ var submit_page = $(this).attr('rel'); $("#"+submit_page).ajaxForm(get_pages_load_options); return false; }); </script> However now it only runs every other option when I change it.

• 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).

• Registration with profile picture using services in Drupal

  - by Fran Ruano

  I've been trying to upload a user profile picture during the user registration using Service 3 and so far I haven't had any luck. I tested passing a hard coded fid in the field "picture" and also tried to pass the fields "filemime", "filename", etc. and it didn't work neither. Any idea about what fields I need to populate? I guess it must be related to this post Using Drupal Services and DIOS SDK for setting user picture in iOS app but it doesn't have and answer neither.

• What Read-eval-print-loops (REPL's) are available for C++ ?

  - by Justin Ethier

  REPL's are very useful for live debugging and experimentation. Most dynamic languages such as Ruby, Python, etc come with one built-in, however it is more difficult to build one for a statically-typed language such as C++. Despite the technical challenges, are there any REPL's available for C++?

I'd like to be able to build html forms from a remote wsdl for each method... Sorry for my horrible English :D

• ASP.NET MVC 3 NOT showing appropriate view, action called using jquery

  - by TunAntun

  I have a small problem. My action is : public ViewResult SearchForRooms(int HotelDDL) { List<Room> roomsInHotel = bl.ReturnRoomsPerHotel(HotelDDL); return View(roomsInHotel); } Here is the jquery that is calling the action: <script type="text/javascript" language="javascript"> $(document).ready(function () { $("#HotelDDL").change(function () { var text = $("#HotelDDL option:selected").text(); var value = $("#HotelDDL option:selected").val(); alert("Selected text=" + text + " Selected value= " + value); $.post("/Home/SearchForRooms", { HotelDDL: $("#HotelDDL option:selected").val() }); }); }); </script> And finally, here is the View that should be called: @model IEnumerable<RoomReservation.Entities.Entities.Room> @{ ViewBag.Title = "Search"; } <h2>Result</h2> <table> <tr> <th> City </th> <th> Hotel </th> <th> Room label </th> <th> Number of beds </th> <th> Price per night </th> <th></th> </tr> @foreach (var item in Model) { <tr> <td> @Html.DisplayFor(modelitem=>item.Hotel.City.Name) </td> <td> @Html.DisplayFor(modelItem => item.Hotel.Name) </td> <td> @Html.DisplayFor(modelItem => item.Name) </td> <td> @Html.DisplayFor(modelItem => item.NumberOfBeds) </td> <td> @Html.DisplayFor(modelItem => item.PricePerNight) </td> </tr> } </table> Everthing is working ok (databse return all rooms correctly) except final view rendering. I have tried Phil's tool but it doesn't give me any suspicious hints: RouteDebug.RouteDebugger.RewriteRoutesForTesting(RouteTable.Routes); So, why is it not showing after jscript send it's post method to SearchForRooms()? Thank you P.S. If you need any other piece of code please just say so.

• login restriction with ldap, but where to store the functional rights/access control list?

  - by jrEwing

  Question is: Best practices when using LDAP authentication like MS ActiveDirectory but having complex access control rights inside each application. Did you put it all in the LDAP or did you link it with information in the application? Looking to build this in asp.net mvc 2 and using membership features, so best practice here i guess is that we roll our own custom provider to acomplish this...
