• Converting an array to JSON and passing that to asmx

  - by user96403

  Hi. I am trying to use JSON.stringify() (from json2.js of json[dot]org ) to convert a JavaScript array to JSON string and to pass it to an asmx web method. I use jQuery AJAX. The call reaches the web method where I take a List <Object> as parameter but I get an empty list there in debug mode. My JSON string looks like well formed with all data , I even tried having single-quotes and double-quotes(escaped) around the 'names' of the JSON string. Please help.

• Is it a good idea to "migrate business logic code into our domain model"?

  - by Bytecode Ninja

  I am reading Hibernate in Action and the author suggests to move business logic into our domain models (p. 306). For instance, in the example presented by the book, we have three entities named Item, Bid, and User and the author suggests to add a placeBid(User bidder, BigDecimal amount) method to the Item class. Considering that usually we have a distinct layer for business logic (e.g. Manager or Service classes in Spring) that among other things control transactions, etc. is this really a good advice? Isn't it better not to add business logic methods to our entities? Thanks in advance.

• What is the best practise to create MSI with some other child MSI as prerequisite?

  - by sankar

  Currently we are using Innosetup as a bootstrapper to install the MSI prerequisites. It makes bit complex to maintain the setup. I found that burn tool which may help us to resolve this issue by having a single setup to install whatever we need. I could not find either documentation or sample for this tool. Is anyone have idea about this? or you can give me the alternate solution if you have. Looking for the alternate soltuion for the actions that we do with ISS bootstrapper now: Extract the files (Main setup, Prerequisite setup) Need to ensure prerequisites status and install on demand. Start main install.

• SQL - Finding continuous entries of a given size.

  - by ByteMR

  I am working on a system for reserving seats. A user inputs how many seats they wish to reserve and the database will return a set of suggested seats that are not previously reserved that matches the number of seats being reserved. For instance if I had the table: SeatID | Reserved ----------------- 1 | false 2 | true 3 | false 4 | false 5 | false 6 | true 7 | true 8 | false 9 | false 10 | true And the user inputs that they wish to reserve 2 seats, I would expect the query to return that seats (3, 4), (4, 5), and (8, 9) are not reserved and match the given number of input seats. Seats are organized into sections and rows. Continuous seats must be in the same row. How would I go about structuring this query to work in such a way that it finds all available continuous seats that match the given input?

• ColumnCount in DataGridView remains 0 after assigning data source

  - by Manan Shah

  I am having trouble with the following simple code List<Car> tempList = new List<Car>(); BindingSource bindingSource = new BindingSource(); bindingSource.DataSource = tempList; dgTempView.DataSource = bindingSource; Here, dgTempView is a data grid view After the above lines execute, the column count in the datagrid view remains 0. And when I try adding a Car instance in tempList, I get an error saying that 'no row can be added to a datagridview control that does not have columns' . I am not able to understand what am I missing here

• 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.

• Batch INSYNC help needed...

  - by Raja Reddy

  I have a INSYNC batch to 'extract' certain conditioned data output. For instance, below insync code extracts the data if 44 pos has a value of '25'. Question here is, I wanna get the output in a sorted manner based on a particular field. Can we incorporate the SORT criteria below. Suggestions are really appreciated.

• Consuming all touchEvents not preventing scrolling on the blackberry storm

  - by Some guy with a headache

  Hello, I am trying to make a custom control for the BlackBerry Storm using SDK v5.0. This control needs to disable scrolling while the user is dragging elements within a field. The problem is that even if I my control consumes every single touch event send to it, when the user lifts their finger off the screen it still flings up or down as if its finishing a scroll action. Does anyone know of a way to prevent this from happening or what I might be doing wrong ? Thank you.

• Panel widget overlapping other contents in android

  - by walker

  I'm trying to utilize the Panel widget introduced in android-misc-widgets. It's been good so far. Now the problem is the sliding panel overlaps my top menu bar. For clarification look at the following screenshots. This is when I open panel using drag gesture (no problem here): This is when I open the panel with a single tap (look at the icons overlapping the top menu): There is one other problem, If there is any content inside the activity, opening the panel pushes that content out of the screen!

• Php writing to file - empty ?

  - by The Devil

  Hey, I've been struggling with writing a single string into a file. I'm using just a simple code under Slackware 13: $fp = fopen('/my/absolute/path/data.txt', 'w'); fwrite($fp, 'just a testing string...'); fclose($fp); The file gets created (if it's not already created) but it's empty ?! The directory in which this file is written is owned by apache's user & group (daemon.daemon) and has 0777 permissions. This has never happened to me before. I'm curious what's the reason I'm not able to write inside the file ? Thanks in advance.

• Android Lightweight HTML Template Engine

  - by Anthoni Gardner

  Hello, I am after a very lightweight template engine that supports / can be embedded inside Android programs. I've looked at the MiniTemplator (I think that is how you spell it) and that looks great but it loads in only from file and I need to load templates from string and I am not fully confident in changing that code lol. Can anyone recommend a very lightweight (preferably no jars, single source files etc) that I can use ? I do not need it to parse XML or anything like, just normal HTML files with keywords embedded into them betwee %% tags etc. Regards Anthoni

• Multiple Broadcast Messages with Less Data or Less Broadcast Messages with More Data?

  - by niko

  Hi, I am developing an application which is communicating with the server. Tha application can perform log-in and get different parameters from server. The application consists of a RESTful client (custom class for making requests), Communication Service (the service which runs in the background) and the main activity. For now I created multiple broadcast messages and multiple broadcast receivers in the main activity so when the application performs login operation a receiver (loginBroadcastReceiver) in the main activity receives a message and when another parameter is received from the server different message is broadcasted and another receiver handles the message. This way however the application performance is poor but I am not sure whether it is due to multiple broadcast receivers. Does anyone know what is the best way to exchange data between service and main activity - is it better to create a single broadcast receiver and retrieve all parameters from message or is it better to initialize multiple broadcast receivers for multiple parameters? I would appreciate if you could provide any useful resource about the topic because I'm writing the thesis and it would be good if the solution could be explained.

• Authlogic auto login fails on registration with STI User model

  - by Wei Gan

  Authlogin by default is supposed to auto login when the user's persistence token changes. It seems to fail in my Rails app. I set up the following single table inheritance user model hierarchy: class BaseUser < ActiveRecord::Base end class User < BaseUser acts_as_authentic end create_table "base_users", :force => true do |t| t.string "email" t.string "crypted_password" t.string "persistence_token" t.string "first_name" t.string "last_name" t.datetime "created_at" t.datetime "updated_at" t.string "type" end To get auto login to work, I need to explicitly log users in in my UsersController: def create @user = User.new(params[:user]) if @user.save UserSession.create(@user) # EXPLICITLY LOG USER IN BY CREATING SESSION flash[:notice] = "Welcome to Askapade!" redirect_to_target_or_default root_url else render :action => :new end end I was wondering if it's anything to do with STI, or that the table is named "base_users" and not "users". I set it up before without STI and it worked so I'm wondering why once I put in place this hierarchy, it fails. Thanks!

• Forcing Spring web services to add the xsd namespace to the response

  I'm using the Spring WS version 1.5.8. My response looks like this: <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"> <SOAP-ENV:Header/> <SOAP-ENV:Body> ... </SOAP-ENV:Body> </SOAP-ENV:Envelope> However, my client (whom I integrate with) requires that I will add more namespace declerations in order for the parsing to succeed: <?xml version="1.0" encoding="UTF-8"?> <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <soapenv:Body> ... </soapenv:Body> </soapenv:Envelope> How can I do it?

• How to make script paths inside user control independent of page hierarchy.

  - by Rohit

  My website is organized in the following folder structure Root Pages CustomerManagement DepartMentManagement Script UserControls Now i have a user control inside userControl Folder. I have to use a external js file. So i use it this way <script type="text/javascript" language="javascript" src="../Script/slider.js"></script> My understanding is that since both are under root so i have used a single .. Now what happens is that when this usercontrol is used inside DepartMentManagement it checks for script folder inside CustomerManagement as .. refers to one hierarchy above and script file is not found.Even using a ~ doesnot work. I want to make this script path independent of the path where this control is used. I don't want to move script reference code to the page as control requires script mot page.Please tell me how to achieve this.

• Graphical database monitoring tool for debugging

  - by salle55

  I would love a tool that in real-time showed changes in a set of predefined tables in a graphical way, for example different colors on fields that has changed value, added records, deleted records etc. I don't want a list of all transactions (like SQL Server Profiler), instead a clever visualized more graphical approach where you can get a great overview if you are just monitoring a few tables. I realize the visualization would be hard if there is a lot of transactions against the database, but with monitoring on a few tables and a single session during debugging it would be possible. Does something like this exist? I think it would be great for debugging! Preferably for SQL Server and/or MySQL.

• SL4: Root element is missing

  - by Number8

  Hello, I know this has been asked elsewhere, but none of the questions or answers helped. I open an xml file in my SL 4 app: StreamResouceInfo sri = Application.GetResourceStream(new System.Uri("z.xml", UriKind.Relative)); if (null != sri) { XDocument xDoc = XDocument.Load(sri.Stream); } "Root element is missing" exception. The xml: Hmm, can't seem to post the xml... It is well-formed and valid, with a single root node and all tags closed. Thanks for any hints...

• Why doesn't an octal literal as a string cast to a number?

  - by Andy E

  In JavaScript, why does an octal number string cast as a decimal number? I can cast a hex literal string using Number() or +, why not an octal? For instance: 1000 === +"1000" // -> true 0xFF === +"0xFF" // -> true 0100 === +"0100" // -> false - +"0100" gives 100, not 64 I know I can parse with parseInt("0100" [, 8]), but I'd like to know why casting doesn't work like it does with hex and dec numbers. Also, does anyone know why octal literals are dropped from ECMAScript 5th Edition in strict mode?

• Pros and Cons of Different macro function / inline methods in C

  - by Robert S. Barnes

  According to the C FAQ, there are basically 3 practical methods for "inlining" code in C: #define MACRO(arg1, arg2) do { \ /* declarations */ \ stmt1; \ stmt2; \ /* ... */ \ } while(0) /* (no trailing ; ) */ or #define FUNC(arg1, arg2) (expr1, expr2, expr3) To clarify this one, the arguments are used in the expressions, and the comma operator returns the value of the last expression. or using the inline declaration which is supported as an extension to gcc and in the c99 standard. The do { ... } while (0) method is widely used in the Linux kernel, but I haven't encountered the other two methods very often if at all. I'm referring specifically to multi-statement "functions", not single statement ones like MAX or MIN. What are the pros and cons of each method, and why would you choose one over the other in various situations?

• WCF Runtime Caching

  - by francois

  Hi I'm using the following code to cache objects. HttpRuntime.Cache.Insert("Doc001", _document); HttpRuntime.Cache.Remove("Doc001"); I would like to know were the cache is stored? (On the client PC or the IIS server) Is this a save way of cache objects and by adding and removing cache in this way will it influence any of the other clients, say for instance i've got 2 clients connected and both are storing cache "*HttpRuntime.Cache.Insert("Doc001", _document);*" and one client removes the cache, is it only removed on a client level?

• Why doesn't C have rotate left/right operators?

  - by icepack

  A bit of a philosophical question, I suppose. Hope it belongs here. C language has the standard set of bit-wise operations, including OR, AND, XOR, SHIFT LEFT/RIGHT, NOT. Anyone has an idea why rotate left/rotate right isn't included in the language? These operators are of the same complexity as other bit-wise operators and normally require a single assembly instruction, like the others. Besides, I can think of a lot of uses for rotate operator, probably not less than, say, xor operator - so it sounds a bit strange to me that they aren't included in C along with the rest. Edit: Please stop suggesting implementations of rotation operators. I know how to do that and it's not what the question about.

• Constants by another name

  - by Dave DeLong

  First off, I've seen this question and understand why the following code doesn't work. That is not my question. I have a constant, which is declared like; //Constants.h extern NSString * const MyConstant; //Constants.m NSString * const MyConstant = @"MyConstant"; However, in certain contexts, it's more useful to have this constant have a much more descriptive name, like MyReallySpecificConstant. I was hoping to do: //SpecificConstants.h extern NSString * const MyReallySpecificConstant; //SpecificConstants.m #import "Constants.h" NSString * const MyReallySpecificConstant = MyConstant; Obviously I cannot do this (which is explained in the linked question above). My question is: How else (besides something like #define MyReallySpecificConstant MyConstant) can I provide a single constant under multiple names?

• Basic Login Script using php and mysql inquiry

  - by Matt

  Attempting to write a check for a login script to see if the username is available. Would the best way to write this query be to check if isset(!_POST[]) for both values (nick and pass) then connect to database WHERE the mysql database for the usernick requested return the user id if the usernick exists evaluate if isset($id) to see if the user name is taken and use that to continue to creating an entry Does this logically sound like a method to check for login without using excessive code sorry for not posting the code, it is on another computer and this computer is locked down by my administrator at work... Also, is there another way to evaluate if a value exists in the database? For instance, instead of setting $id to the return value of the mysql database can i just ping the mysql database for the information and have it return a Boolean result so I am not putting out any user information. Thanks, Matt
