  • Ask Field formatting

    - by developer
    I am using ASK fields in a word document, wherein the user are prompted with questions and the document is then built with the answers that the user type in. My question is that word does not allow more that 200 characters in the prompt box wherein the user types in the questions. Is there a way I can increase its maxlength. Also I want to change the font color of the question asked in the prompt box. Is it possible?

  • ASP.NET MVC Access model data in masterpage

    - by Paul
    I have created a UserSiteBaseController that gets commonly used data and sets the data to a UserSiteBaseViewData viewmodel in a method called SetViewData public T CreateViewData<T>() where T : UserSiteBaseViewData, new() { .... } I then create specific Controllers that inherit from the UserSiteBaseController as well as viewModels that inherit from UserSiteHomeViewData and can be created in the controller like so: public ActionResult Index(string slug) { Slug = slug; var viewData = CreateUserSiteHomeViewData<UserSiteHomeViewData>(); //If invalid slug - throw 404 not found if (viewData == null) return PageNotFound(); viewData.Announcements = _announcementsData.All(slug).ToList(); return View(viewData); } private T CreateUserSiteHomeViewData<T>() where T : UserSiteHomeViewData, new() { T viewData = CreateViewData<T>(); return viewData; } The UserBaseViewData holds data that needs to be use on every page so it would be great to be able to access this data from the Masterpage in a strongly typed manner. Is this possible or am I going about this in the incorrect manner?

Is there some sort of system variable - or something else I haven't checked....?

  • Android game goes blank after pressing home and restarting

    - by sirconnorstack
    I am making an Android game with an Activity called Game, a SurfaceView called GameView and a Thread called GameThread. The Game's onCreate(), I make a new GameView, which makes a new GameThread, where all the game logic and canvas drawing is carried out. However, I'm having some lifecycle difficulties. When I press back and restart it, it works fine, but when I press home and restart it, all I see is a blank screen. Here are the GameView's onSurfaceCreated() and onSurfaceDestroyed(): @Override public void surfaceCreated(SurfaceHolder holder) { mThread.mRunning = true; mThread.mWidth = getWidth(); if(mThread.mWidth > 550) mThread.mWidth = 550; mThread.mHeight = getHeight(); try { mThread.start(); } catch(IllegalThreadStateException e) { } } @Override public void surfaceDestroyed(SurfaceHolder holder) { // Wait for the secondary thread to end before finishing boolean retry = true; mThread.mRunning = false; while (retry) { try { mThread.join(); retry = false; } catch (InterruptedException e) { } } }

  • Searching a Better Solution with Delegates

    - by spagetticode
    Hey All, I am a newbie in C# and curious about the better solution of my case. I have a method which gets the DataTable as a parameter and creates a List with MyClass's variables and returns it. public static List<Campaigns> GetCampaignsList(DataTable DataTable) { List<Campaigns> ListCampaigns = new List<Campaigns>(); foreach (DataRow row in DataTable.Rows) { Campaigns Campaign = new Campaigns(); Campaign.CampaignID = Convert.ToInt32(row["CampaignID"]); Campaign.CustomerID = Convert.ToInt32(row["CustomerID"]); Campaign.ClientID = Convert.ToInt32(row["ClientID"]); Campaign.Title = row["Title"].ToString(); Campaign.Subject = row["Subject"].ToString(); Campaign.FromName = row["FromName"].ToString(); Campaign.FromEmail = row["FromEmail"].ToString(); Campaign.ReplyEmail = row["ReplyEmail"].ToString(); Campaign.AddDate = Convert.ToDateTime(row["AddDate"]); Campaign.UniqueRecipients = Convert.ToInt32(row["UniqueRecipients"]); Campaign.ClientReportVisible = Convert.ToBoolean(row["ClientReportVisible"]); Campaign.Status = Convert.ToInt16(row["Status"]); ListCampaigns.Add(Campaign); } return ListCampaigns; } And one of my another DataTable method gets the DataTable from the database with given parameters. Here is the method. public static DataTable GetNewCampaigns() { DataTable dtCampaigns = new DataTable(); Campaigns Campaigns = new Campaigns(); dtCampaigns = Campaigns.SelectStatus(0); return dtCampaigns; } But the problem is that, this GetNewCampaigns method doesnt take parameters but other methods can take parameters. For example when I try to select a campaign with a CampaignID, I have to send CampaignID as parameter. These all Database methods do take return type as DataTable but different number of parameters. public static DataTable GetCampaignDetails(int CampaignID) { DataTable dtCampaigns = new DataTable(); Campaigns Campaigns = new Campaigns(); dtCampaigns = Campaigns.Select(CampaignID); return dtCampaigns; } At the end, I want to pass a Delegate to my first GetCampaignList Method as parameter which will decide which Database method to invoke. I dont want to pass DataTable as parameter as it is newbie programming. Could you pls help me learn some more advance features. I searched over it and got to Func< delegate but could not come up with a solution.

  • Authlogic: passwords saved in the DB are not working as expected.

    - by user570459
    Hello everyone, Im having trouble with authlogic on my production server. Im able to update passwords in the database but when i try to validate a user using the new password, the validation fails. Please check the below console output. Notice how the salt and crypted_password fields get update before and after the new password is saved. The issue is only on my production server (running passenger). Everything works fine on my development machine. => #<User id: 3, login: "saravk", email: "[email protected]", crypted_password: "9bc86247105e940bb748ab680c0e77d9c44a82ea", salt: "WdVpQIdwl68k8lJWOU"> irb(main):003:0> u.password = "kettik123" => "kettik123" irb(main):004:0> u.password_confirmation = "kettik123" => "kettik123" irb(main):005:0> u.save! => true irb(main):006:0> u.valid_password?("kettik123") => true irb(main):007:0> u.reload => #<User id: 3, login: "saravk", email: "[email protected]", crypted_password: "f059007c56f498a12c63209c849c1e65bb151174", salt: "lVmmczhyGE0gxsbV421A"> irb(main):008:0> u.valid_password?("kettik123") => false The authlogic configuration in my User model.. class User < ActiveRecord::Base acts_as_authentic do |c| c.login_field :email c.validate_login_field false c.validate_email_field false c.perishable_token_valid_for = 1.day c.disable_perishable_token_maintenance = true end I use the email field as the main key for the user. Also the email field is allowed to be blank in some cases (eg a facebook user) Also i belive that my schema is proper (in terms of the length of the salt & crypted password fields) create_table "users", :force => true do |t| t.string "login" t.string "email" t.string "crypted_password", :limit => 128, :default => "" t.string "salt", Any help on this would be highly appreciated.

  • How to use jQuery to generate 2 new associated objects in a nested form?

    - by mind.blank
    I have a model called Pair, which has_many :questions, and each Question has_one :answer. I've been following this railscast on creating nested forms, however I want to generate both a Question field and it's Answer field when clicking on an "Add Question" link. After following the railscast this is what I have: ..javascripts/common.js.coffee: window.remove_fields = (link)-> $(link).closest(".question_remove").remove() window.add_fields = (link, association, content)-> new_id = new Date().getTime() regexp = new RegExp("new_" + association, "g") $(link).before(content.replace(regexp, new_id)) application_helper.rb: def link_to_add_fields(name, f, association) new_object = f.object.class.reflect_on_association(association).klass.new fields = f.simple_fields_for(association, new_object, :child_index => "new_#{association}") do |builder| render(association.to_s.singularize + "_fields", :f => builder) end link_to_function(name, "window.add_fields(this, \"#{association}\", \"#{escape_javascript(fields)}\")", class: "btn btn-inverse") end views/pairs/_form.html.erb: <%= simple_form_for(@pair) do |f| %> <div class="row"> <div class="well span4"> <%= f.input :sys_heading, label: "System Heading", placeholder: "required", input_html: { class: "span4" } %> <%= f.input :heading, label: "User Heading", input_html: { class: "span4" } %> <%= f.input :instructions, as: :text, input_html: { class: "span4 input_text" } %> </div> </div> <%= f.simple_fields_for :questions do |builder| %> <%= render 'question_fields', f: builder %> <% end %> <%= link_to_add_fields "<i class='icon-plus icon-white'></i> Add Another Question".html_safe, f, :questions %> <%= f.button :submit, "Save Pair", class: "btn btn-success" %> <% end %> _question_fields.html.erb partial: <div class="question_remove"> <div class="row"> <div class="well span4"> <%= f.input :text, label: "Question", input_html: { class: "span4" }, placeholder: "your question...?" %> <%= f.simple_fields_for :answer do |builder| %> <%= render 'answer_fields', f: builder %> <% end %> </div> </div> </div> _answer_fields.html.erb partial: <%= f.input :text, label: "Answer", input_html: { class: "span4" }, placeholder: "your answer" %> <%= link_to_function "remove", "remove_fields(this)", class: "float-right" %> I'm especially confused by the reflect_on_association part, for example how does calling .new there create an association? I usually need to use .build Also for a has_one I use .build_answer rather than answers.build - so what does this mean for the jQuery part?

  • Behaviour to simulate an enum implementing an interface

    - by fearofawhackplanet
    Say I have an enum something like: enum OrderStatus { AwaitingAuthorization, InProduction, AwaitingDespatch } I've also created an extension method on my enum to tidy up the displayed values in the UI, so I have something like: public static string ToDisplayString(this OrderStatus status) { switch (status) { case Status.AwaitingAuthorization: return "Awaiting Authorization"; case Status.InProduction: return "Item in Production"; ... etc } } Inspired by the excellent post here, I want to bind my enums to a SelectList with an extension method: public static SelectList ToSelectList<TEnum>(this TEnum enumObj) however, to use the DisplayString values in the UI drop down I'd need to add a constraint along the lines of : where TEnum has extension ToDisplayString Obviously none of this is going to work at all with the current approach, unless there's some clever trick I don't know about. Does anyone have any ideas about how I might be able to implement something like this?

  • Android: How to properly exit application when inconsistent condition is unavoidable?

    - by Bevor
    First of all I already read about all this discussion that it isn't a good idea to manually exit an Android application. But in my case it seems to be needed. I have an AsyncTask which does a lof of operations in background. That means downloading data, saving it to local storage and preparing it for usage in application. It could happen that there is no internet connection or something different happens. For all that cases I have an Exception handling which returns the result. And if there is an exception, the application is unusable so I need to exit it. My question is, do I have to do some unregistration unloading or unbinding tasks or something when I exit the application by code or is System.exit(0) ok? I do all this in an AsyncTask, see my example: public class InitializationTask extends AsyncTask<Void, Void, InitializationResult> { private ProcessController processController = new ProcessController(); private ProgressDialog progressDialog; private Activity mainActivity; public InitializationTask(Activity mainActivity) { this.mainActivity = mainActivity; } @Override protected void onPreExecute() { super.onPreExecute(); progressDialog = new ProgressDialog(mainActivity); progressDialog.setMessage("Die Daten werden aufbereitet.\nBitte warten..."); progressDialog.setIndeterminate(true); //means that the "loading amount" is not measured. progressDialog.setCancelable(false); progressDialog.show(); }; @Override protected InitializationResult doInBackground(Void... params) { return processController.initializeData(); } @Override protected void onPostExecute(InitializationResult result) { super.onPostExecute(result); progressDialog.dismiss(); if (!result.isValid()) { AlertDialog.Builder dialog = new AlertDialog.Builder(mainActivity); dialog.setTitle("Initialisierungsfehler"); dialog.setMessage(result.getReason()); dialog.setPositiveButton("Ok", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { dialog.cancel(); //TODO cancel application System.exit(0); } }); dialog.show(); } } }

  • executorservice to read data from database in chuncks and run process on them

    - by TazMan
    I'm trying to write a process that would read data from a database and upload it onto a cloud datastore. How can I decide the partition strategy of the data? I want to query the table in chunks and process each chunk in 10 threads. Each thread basically will send the data to an individual node on a 10 node cluster on the cloud.. Where in the below multi threading code will the dataquery to extract and send 10 concurrent requests for uploading data to cloud would be? public class Caller { public static void main(String[] args) { ExecutorService executor = Executors.newFixedThreadPool(10); for (int i = 0; i < 10; i++) { Runnable worker = new DomainCDCProcessor(i); executor.execute(worker); } executor.shutdown(); while (!executor.isTerminated()) { } System.out.println("Finished all threads"); } }

  • GWT : NULL Session

    I'm using spring4gwt in my project. I have the following login service implementation: @Service("loginService") public class LoginServiceImpl extends RemoteServiceServlet implements LoginService { @Override @Transactional(propagation = Propagation.REQUIRED, rollbackFor = Exception.class) public UserBean checkUser(String userName, String password) throws Exception { HttpSession httpSession = getThreadLocalRequest().getSession(); } } When i call the loginService.checkUser("test","test") (In hosted mode), I get a null pointer exception, as getThreadLocalRequest() returns NULL instead of the actual session. I didn't try in web mode yet. Why would I get a null session ? Does it have something to do with spring4gwt ? Thank you

  • Rails + Passenger CSS problem

    - by Dan
    I'm trying to deploy my first Rails app. At first, I was getting the following error: ActionView::TemplateError (Permission denied) I set the permissions of the stylesheets folder to 777 (just for now until I work out what's going wrong) and the application started to work. However, it is not picking up any of the stylesheets (everything is displayed in plain text). If I view the source code and click the CSS links, I just get a blank page. Javascripts however, seem to be working just fine. VHost Config: <VirtualHost *:80> ServerName xxxx.xxx.com DocumentRoot /home/myapp/public <Directory /home/myapp/public> Allow from All AllowOverride all Options -MultiViews </Directory> </VirtualHost> Can anyone help? Any advice appreciated. Thanks.

  • Question About NerdDinner Controller Constructors

    - by Gavin Draper
    I've been looking at the Nerd Dinner app, more specifically how it handles its unit tests. The following constructors for the RSVPController are confusing my slightly public RSVPController() : this(new DinnerRepository()) { } public RSVPController(IDinnerRepository repository) { dinnerRepository = repository; } From what I can tell the second one is used by the unit tests so it can use Fake repositories. What I cant work out is what the first constructor does. It doesn't seem to ever set the dinnerRepository variable, it seems to imply its inheriting from something but I really don't get it. Can anyone explain? Thanks

  • How can I make a read-only ObservableCollection property?

    - by thrag
    I'd like to expose a property on a view model that contains a list of objects (from database). I need this collection to be read-only. That is, I want to prevent Add/Remove, etc. But allow the foreach and indexers to work. My intent is to declare a private field holding the editable collection and reference it with a read-only Public Property. As follows public ObservableCollection<foo> CollectionOfFoo { get { return _CollectionOfFoo; } } However, that syntax just prevents changing the reference to the collection. It doesn't prevent add/remove, etc. What is the right way to accomplish this?

  • Is it possible to use RedirectToAction() inside a custom AuthorizeAttribute class?

    - by Lance McNearney
    Using ASP.Net MVC 2, is there any way to use the RedirectToAction() method of the Controller class inside a class that is based on the AuthorizeAttribute class? public class CustomAttribute : AuthorizeAttribute { protected override bool AuthorizeCore(HttpContextBase context) { // Custom authentication goes here return false; } public override void OnAuthorization(AuthorizationContext context) { base.OnAuthorization(context); // This would be my ideal result context.Result = RedirectToAction("Action", "Controller"); } } I'm looking for a way to re-direct the user to a specific controller / action when they fail the authentication instead of returning them to the login page. Is it possible to have the re-direct URL generated for that controller / action and then use RedirectResult()? I'm trying to avoid the temptation to just hard-code the URL.
