• Does flex not support hashmaps?

  - by Dr.Dredel

  I have a Flex object which collects a DTO from the server. All the fields arrive filled in correctly except for the one that is a HashMap. It arrives as null. I've tried giving it a type of both ArrayCollection and Dictionary, but that hasn't fixed it. Does anyone know if there's an inherent incomaptability between Java HashMap and Flex? If not, what might I be doing wrong here? I'm looking at my jboss console and I see the data being populated correctly in the server side before delivery to the client. However, as it gets to the client, that field is null. I'm ready to kill myself.

• How to allow users to customize a DAL

  - by rsteckly

  Hi, I'm working in ASP.NET in an application where often users want to add fields or change field names. I'd like to be able to have an xml schema in place that is parsed and a dynamic object model created from it that can be accessed throughout the application. My initial reaction is that this is not realistic. I think there is flexibility about the dynamic nature of it. I think the people I'm trying to build this for wouldn't mind recompiling. Even if the app recompiled, I don't know how to abstract away enough in my code access the data to allow for users changing property names, etc. How can you write LINQ when the properties might change? In short, there's two questions here: 1) is there a way to dynamically generate an object model of the database and 2) is there a way to abstract away enough so that code accessing the database doesn't break when properties change?

• What is the scope of JS variables in anonymous functions

  - by smorhaim

  Why does this code returns $products empty? If I test for $products inside the function it does show data... but once it finishes I can't seem to get the data. var $products = new Array(); connection.query($sql, function(err, rows, fields) { if (err) throw err; for(i=0; i< rows.length; i++) { $products[rows[i].source_identifier] = "xyz"; } }); connection.end(); console.log($products); // Shows empty.

• How can I put rows of MySQL data under the appropriate titles using PHP?

  - by sfarbota

  I have the following MySQL table structure: num field company phone website 1 Gas abcd 123456789 abcd.com 2 Water efgh 987654321 efgh.com 3 Water ijkl 321654987 ijkl.com 4 Heat mnop 987654321 mnop.com 5 Gas qrst 123789654 qrst.com ... Is it possible with PHP (maybe using some mixture of GROUP_BY and ORDER_BY) to echo the data to the screen in the following format: Gas: abcd qrst 123456789 123789654 abcd.com qrst.com Water: efgh ijkl 987654321 321654987 efgh.com ijkl.com Heat: mnop 321654987 mnop.com The exact format of it isn't important. I just need for the different rows of data to be listed under the appropriate field with none of the fields repeated. I've been trying to figure this out for a while now, but I'm new to PHP and I can't seem to figure out how to do this, if it's even possible, or if there's a better way to organize my data to make it easier.

• Erlang Mnesia Equivalent of SQL Select FROM WHERE Field IN (value1, value2, value3, ...)

  - by ErJab

  I have an mnesia table with fields say f1, f2, f3. Now if I were to select all the rows with the field value as V1, I would use mnesia:select and match specifications or a simple mnesia:match_object. Now I need to select all the rows which have V1, V2, V3 ... or Vn (a list of arbitrary length) as the value for field f1. In SQL I would do something like SELECT * FROM tablename WHERE f3 IN (V1, V2, V3, ... , Vn) How do I do this in mnesia?

• Should I specify both INDEX and UNIQUE INDEX?

  - by Matt Huggins

  On one of my PostgreSQL tables, I have a set of two fields that will be defined as being unique in the table, but will also both be used together when selecting data. Given this, do I only need to define a UNIQUE INDEX, or should I specify an INDEX in addition to the UNIQUE INDEX? This? CREATE UNIQUE INDEX mytable_col1_col2_idx ON mytable (col1, col2); Or this? CREATE UNIQUE INDEX mytable_col1_col2_uidx ON mytable (col1, col2); CREATE INDEX mytable_col1_col2_idx ON mytable (col1, col2);

• Spring: Inject static member (System.in) via constructor

  - by Julian Lettner

  I wrote some sort of console client for a simple application. To be more flexible, I thought it would be nice to only depend on java.io.Input-/OutputStream, instead of accessing System.in/out directly. I renamed the class ConsoleClient to StreamClient, added setters and made sure that the instance fields are used instead of System.in/out. At the moment my client code looks like this: ApplicationContext appCtx = new ClassPathXmlApplicationContext("..."); StreamClient cc = (StreamClient) appCtx.getBean("streamClient"); cc.setInputStream(System.in); cc.setOutputStream(System.out); cc.run(); // start client Question: Is there a way to move lines 3 and 4 into the Spring configuration (preferably constructor injection)? Thanks for your time.

• What is the correct way to unit test areas around exceptions

  - by Codek

  Hi, Looking at our code coverage of our unit tests we're quite high. But the last few % is tricky because a lot of them are catching things like database exceptions - which in normal circumstances just dont happen. For example the code prevents fields being too long etc, so the only possible database exceptions are if the DB is broken/down, or if the schema is changed under our feet. So is the only way to Mock the objects such that the exception can be thrown? That seems a little bit pointless. Perhaps it's better to just accept not getting 100% code coverage? Thanks, Dan

• Where to execute extra logic for linq to entities query?

  - by Inez

  Let say that I want to populate a list of CustomerViewModel which are built based on Customer Entity Framework model with some fields (like Balance) calculated separately. Below I have code which works for lists - it is implemented in my service layer, but also I want to execute this code when I just get one item from the database and execute is as well in different services where I'm accessing Customers data as well. How should I do this to ensure performance but to to not duplicate code - the one for calculating Balance? public List<CustomerViewModel> GetCustomerViewModelList() { IQueryable<CustomerViewModel> list = from k in _customerRepository.List() select new CustomerViewModel { Id = k.Id, Name = k.Name, Balance = k.Event.Where(z => z.EventType == (int) EventTypes.Income).Sum(z => z.Amount) }; return list.ToList(); }

• user model password field default password field in django

  - by imran-glt

  Hi, I've created a custom user model in my application. This user model is working fine, but there are a couple of problems I have with it. 1) The change password link in the my register.html page doesn't work? 2) The default password box on the add/edit page for a user is a little unfriendly. Ideally, what I'd like is the two password fields from the change password form on the add/edit user form in the admin, which will automatically turn convert the entered password into a valid encrypted password in Django. This would make the admin system MUCH friendlier and much more suited to my needs, as a fair number of user accounts will be created and maintained manually in this app, and the person responsible for doing so will likely be scared off at the sight of that admin field, or just type a clear text password and wonder why it doesn't work. Is this possible / How do I do this?

• Adding data in multiple tables in vb.net

  This is a winform and I'm using mysql as a database, here is my code: I'm trying to add data into multiple tables.

• C++ a class with an array of structs, without knowing how large an array I need

  - by Dominic Bou-Samra

  New to C++, and for that matter OO programming. I have a class with fields like firstname, age, school etc. I need to be able to store other information like for instance, where they have travelled, and what year it was in. I cannot declare another class specifically to hold travelDestination and what year, so I think a struct might be best. This is just an example: struct travel { string travelDest; string year; }; The issue is people are likely to have travelled different amounts. I was thinking of just having an array of travel structs to hold the data. But how do I create a fixed sized array to hold them, without knowing how big I need it to be? Perhaps I am going about this the completely wrong way, so any suggestions as to a better way would be appreciated.

• How to set labels inside textfields for username and password like facebook?

  - by NAVEED

  I have a login form for my website. This login form have two text fields, username and password. Currently I am placing labels(username, password) just before textfields. But now I want to removed these two labels and want to show text(username, password) inside textfield. When user focuses on these textfields then texts should be removed and user can enter his desired username and password. I have also noticed that when user open a login form then font color of text(username, password) populated in textfield(username, password) is of diffent color and when user start typing in that field then previous text is removed and new font color is black. How is it possible?

• Freebase Query with "JOINS"

  - by codemonkey

  ... Yeah, yeah, I know traditional joins don't exist. I actually like the freebase query methodology in theory, just having a little trouble getting it to actually work for me : ) Anyone have a dumb-simple example of getting Freebase data via MQL that pulls from two different "tables"? In particular, I'm trying to get automotive data... so for example, pulling fields from both /automotive/model_year and /automotive/trim_year. I've read the documentation (for hours actually). There's a distinct possibility that I'm looking right at such an example somewhere and just not seeing it because my OLTP brain just doesn't comprehend what it's seeing. * Note * ... that the two "types" I'm working with above are siblings, not parent/child. Does freebase even allow joining data between sibling nodes... I see examples of queries pulling from parent/child, but not from siblings I don't think (or I've overlooked them).

• SQL select statement

  - by kwokwai

  Hi all, I got a Table which has two fields: Point, and Level, with some sample data as follows: ----------------------- Point | Level ----------------------- 10 | Level 1 20 | Level 2 30 | Level 3 40 | Level 4 Suppose that there is a user who has 25 points, to find the Level in which this user is in, the Select statement I used was: Select Level from Table where Point < 30 AND Point > 20; But the Select SQL ststament is a hard-copy one where you can see the ponts 30 and 20 are fixed. I want to alter the Select statement so that the new SQL Select statement can be applied to all users with different points, but I don't know how to do it.

• MYSQL - Help with a more complicated Query

  - by Joe

  I have two tables: tbl_lists and tbl_houses Inside tbl_lists I have a field called HousesList - it contains the ID's for several houses in the following format: 1# 2# 4# 51# 3# I need to be able to select the mysql fields from tbl_houses WHERE ID = any of those ID's in the list. More specifically, I need to SELECT SUM(tbl_houses.HouseValue) WHERE tbl_houses.ID IN tbl_lists.HousesList -- and I want to do this select to return the SUM for several rows in tbl_lists. Anyone can help? I'm thinking of how I can do this in a SINGLE query since I don't want to do any mysql "loops" (within PHP).

• How to use less memory while running a task in Symfony 1.4?

  - by Guillaume Flandre

  I'm using Symfony 1.4 and Doctrine. So far I had no problem running tasks with Symfony. But now that I have to import a pretty big amount of data and save them in the database, I get the infamous "Fatal Error: Allowed memory size of XXXX bytes exhausted" During this import I'm only creating new objects, setting a few fields and saving them. I'm pretty sure it has something to do with the number of objects I'm creating when saving data. Unsetting those objects doesn't do anything though. Are there any best practices to limit memory usage in Symfony?

• Wordpress order/sort problem

  - by Spencer

  Hi, The Problem: I would like to sort my posts based on custom fields, when the user clicks on a link. I don't know if there is a parameter that can be passed via url to reorder posts. Comparison: I would like it to work similar to how you can sort songs in iTunes. The user simply clicks the "Artist" button and the songs are reorder alphabetically by artist's name. Example: The custom field could be the location where I was when I wrote the post. "Location = home" or "Location = office" etc. When the user click a links the page is reload with the posts reordered. Posts from home before ones from the office. Thanks for the help.

• Reset UITextField's original placeholder text

  - by Michael

  I'm adding some user feedback mechanism into my app. The user types some comments into a text field and when that editing is done it updates a UITextView. Then when the user hits the submit button and moves on in the app the user may have need to send more feedback from the same form for a different item. I can reset the other fields and labels in the app to their default values when I hide the view, but not the textField (?). How can I reestablish the placeholder text next time the user accesses this view? Your suggestions are humbly appreciated.

• Need alternative field names for these reserved words

  - by MattSlay

  “type” and “class” are likely reserved or problematic words in C# and/or Ruby, two languages I may use to program against my new database schema in the future. So, in order to avoid potential conflicts with those languages, I’m looking for alternative names for these field names in my tables. In this case, it is from my Machines table, where I have: “class” field (values would be something like “manual” or “computerized”) and “type” field (values would be “lathe” or “mill”) I could call the fields “machineclass” and “machinetype”, but that is inconsistent with naming scheme in the rest of my schema (meaning, I do not re-use the table name in the field… For instance, I use Machine.name, not Machine.machinename) Any thought on this madness?

• Using Multiple Foreign Keys to the same table in LINQ

  - by Graeme

  I have a table Users and a table Items In the Items table, I have fields such as ModifiedBy CreatedBy AssignedTo which all have a userId integer. The database is set up to have these as foreign keys back to the Users table. When using LINQToSQL, the relationships which are automatically built from the dbml end up giving me names like User, User1 and User2 e.g. myItem.User1.Name or myItem.User2.Name Obviously this isn't very readable and I'd like it be along the lines of myItem.CreatedByUser.Name or myItem.ModifiedByUser.Name etc I could change the names of the relationships but that means I have to redo that every time I change the db schema and refresh the dbml. Is there any way round this?

• MVC paths in Extjs

  - by Oleg

  I have got a ExtJs application (MVC). So, I define many controllers, models, views and stores. At now, the structure of my project is not easy. For example my model: Ext.define('KP.model.account.AccountList', { extend: 'Ext.data.Model', fields: ['parameter', 'string_value'] }); I define my store with model like this: Ext.define('KP.store.account.AccountList', { extend: 'Ext.data.Store', alias: 'store.s_AccountList', model: 'KP.model.account.AccountList', ...................................... }); If I want to move some .js files, I must rewrite many paths in classes definitions. So, how can I declare my classes (by alias maybe) and use them more effectively? It's need, If I move files on files tree. Thanks!
