  • How value objects are saving and loading?

    - by yeraycaballero
    Since there isn't respositories for value objects. How can I load all value objects? Suppose we are modeling a blog application and we have this classes: Post (Entity) Comment (Value object) Tag (Value object) PostsRespository (Respository) I Know that when I save a new post, its tags are saving with it in the same table. But how could I load all tags of all posts. Has PostsRespository got a method to load all tags? I usually do it, but I want to know others opinions

  • inputAccessoryView not hide the view when -resignFirstResponder?

    - by Sam Jarman
    I have attached a toolbar with a UITextField and UIButton to the keyboard when it becomes the first responder via the user taping inside the textfield textField.inputAccessoryView = theToolbar; Problem is, the toolbar disappears when the keyboard is dismissed, thus preventing any further input. Any ideas on how to make the toolbar go back to the bottom of the screen rather than off it completely? I'm thinking a delegate method might help but Im really not too sure. It seems once the inputAccessoryView always the inputAccessoryView :( Cheers

  • When would isSearchable return false for an Oracle JDBC column?

    - by Ian Varley
    In what cases would a call to java.sql.ResultSetMetaData.isSearchable(int col) return false for an Oracle database? The documentation for the method doesn't really answer the question: "Indicates whether the designated column can be used in a where clause." I can think of only one case - when the column is the result of an aggregate function (in which case it would have to be part of a HAVING filter, not a WHERE filter). Are there any other cases?

  • Faking User Roles in Sitecore 6.2

    - by Jesse Millikan
    The Faking User Roles document in SDN appears to give exactly what I need. I have a few "roles" that I have access to through stored procedure calls I don't control, read-only, via a CRM I don't have direct access to. Unfortunately, I can't find the method AddRole, or even the class UserItem, by its present name. Does this functionality exist in Sitecore 6.2? If so, where is it?

  • Calling another Seam permission resolver from Drools

    - by ciaron
    I'm just discovering Drools with Seam, and I would like to call my PersistentPermissionResolver directly from the Drools code. Do you know if there is a way to achieve that and is that a good idea? I would also like to call the hasPermission method from my xxx.page.xml as follows: <restrict>#{s:hasPermission('menu_32', 'view')}</restrict>

  • ruby on rails - link_to() problem

    - by Oded Harth
    Hi, I made this link in order to destroy a comment :   <%= link_to 'Destroy Comment', [comment.post, comment], :confirm => 'Are you sure?', :method => :delete %> this suppose to send to the destroy action in the comments_controller. the problem is that it searches for the 'show' action, Instead of the 'destroy' action : Unknown action The action 'show' could not be found for CommentsController Do you think you know why it does that? Thanks, Oded edit: problem solved I used 'button_to'

  • Is it possible to use System.Configuration, if there is no local app.config? And how to, if it is po

    - by Aen Sidhe
    Hello. I have a client apllication that run in very restricted area - it has no direct access to computer, where it is running. I don't want to invent another one System.Configuration system to configure my application. But there is no method in ConfigurationManager, that allows to load configuration from string or Stream. It seems to me that it's impossible to use a ConfigurationManager in this particular scenario, but may be (and I hope to) wrong?

  • Performance - FunctionCall vs Event vs Action vs Delegate

    - by hwcverwe
    Currently I am using Microsoft Sync Framework to synchronize databases. I need to gather information per record which is inserted/updated/deleted by Microsoft Sync Framework and do something with this information. The sync speed can go over 50.000 records per minute. So that means my additional code need to be very lightweight otherwise it will be a huge performance penalty. Microsoft Sync Framework raises an SyncProgress event for each record. I am subscribed to that code like this: // Assembly1 SyncProvider.SyncProgress += OnSyncProgress; // .... private void OnSyncProgress(object sender, DbSyncProgressEventArgs e) { switch (args.Stage) { case DbSyncStage.ApplyingInserts: // MethodCall/Delegate/Action<>/EventHandler<> => HandleInsertedRecordInformation // Do something with inserted record info break; case DbSyncStage.ApplyingUpdates: // MethodCall/Delegate/Action<>/EventHandler<> => HandleUpdatedRecordInformation // Do something with updated record info break; case DbSyncStage.ApplyingDeletes: // MethodCall/Delegate/Action<>/EventHandler<> => HandleDeletedRecordInformation // Do something with deleted record info break; } } Somewhere else in another assembly I have three methods: // Assembly2 public class SyncInformation { public void HandleInsertedRecordInformation(...) {...} public void HandleUpdatedRecordInformation(...) {...} public void HandleInsertedRecordInformation(...) {...} } Assembly2 has a reference to Assembly1. So Assembly1 does not know anything about the existence of the SyncInformation class which need to handle the gathered information. So I have the following options to trigger this code: use events and subscribe on it in Assembly2 1.1. EventHandler< 1.2. Action< 1.3. Delegates using dependency injection: public class Assembly2.SyncInformation : Assembly1.ISyncInformation Other? I know the performance depends on: OnSyncProgress switch using a method call, delegate, Action< or EventHandler< Implementation of SyncInformation class I currently don't care about the implementation of the SyncInformation class. I am mainly focused on the OnSyncProgress method and how to call the SyncInformation methods. So my questions are: What is the most efficient approach? What is the most in-efficient approach? Is there a better way than using a switch in OnSyncProgress?

  • where can I get these kind of exercises to solve?

    - by flash
    Recently I did a Java programming exercise successfully which was sent by a recruiting firm, The problem statement goes like this 'There are two text files FI(records abt files and directory information) and FS(containing blocks of data) which represent a file Index and file System respectively and I was supposed to write a static read method in a class which will read the file from the FS depending upon the path string provided using FI' My question is where can I get these kind of exercises to solve, the complexity should be above average to tough.

  • Create DB in Sql Server based on Visio Data Model

    - by Yaakov Ellis
    I have created a database model in Visio Professional (2003). I know that the Enterprise version has the ability to create a DB in Sql Server based on the data in Visio. I do not have the option to install Enterprise. Aside from going through the entire thing one table and relationship at a time and creating the whole database from scratch, by hand, can anyone recommend any tool/utility/method for converting the visio database model into a Sql Script that can be used to create a new DB in Sql Server?

  • getJSON and variable scope in javascript

    - by nillls
    Hi! In order to make function calls to our back-end php code we've implemented something called an ActionProxy like this: function ActionProxy(action, input, callback){ $.post("ActionProxy.php?method="+action, { data: input}, function(data, textStatus, XMLHttpRequest){ //return data.ResponseWhatever } }); The problem we're having is that using data outside the ActionProxy is impossible due to variable scope limitations (we assume), setting var res = data.ResponseWhatever or return data.ResponseWhatever is pretty futile. How would one handle these responses most appropriately so that functions calling the actionproxy can access the response values?

  • Is there a way to listen for changes in an MySQL database table using Java and JDBC?

    - by adrian7
    I have a number of users which are logged in at a time in my desktop application. They are working on the same table (create, read, update, delete data) so I have to update their views, to reflect changes, every few seconds - currently I am thinking to use a different thread to do that. I am using the MySQL database engine. Is there a way, using JDBC, to listen for changes on a specific table in the database and triggering a Java method only when changes are made?
