• CSS class equivalent for LaTeX

  - by Ryan Scott Bardsley

  I am trying to figure out if there is a way to apply the CSS methodology to the LaTeX template I am building. What I would like to do is to have a set of classes that apply a specific style treatment to the bracketed words. For example: If I have three paragraphs of text, I want to have all of the paragraphs have [0.5cm] of spacing after the last line without having to add \\[0.5cm] after each paragraph. Is there a LaTeX equivalent of defining the treatment for all paragraphs in the preamble so that it cascades throughout my document? The equivalent of: <style> p {padding-bottom:0.5cm} </style> I want to be able to specify multiple version of these CSS-like LaTeX classes throughout my document, so I don't need a specific solution. I need help understanding how to add custom labels/names/classes to the preamble and an example of how to use them in the document itself. Thanks! Ryan

• WindowsForms difference to simple Console App

  - by daemonfire300

  I currently started to "port" my console projects to WinForms, but it seems I am badly failing doing that. I am simply used to a console structure: I got my classes interacting with each other depending on the input coming from the console. A simple flow: Input -> ProcessInput -> Execute -> Output -> wait for input Now I got this big Form1.cs (etc.) and the "Application.Run(Form1);" But I really got no clue how my classes can interact with the form and create a flow like I described above. I mean, I just have these "...._Click(object sender....)" for each "item" inside the form. Now I do not know where to place / start my flow / loop, and how my classes can interact with the form.

• Do we need HyperJAXB generated hashCode & equals methods?

  - by Marcus

  We've generated some (well a lot) of classes using HyperJAXB. All of the classes implement Equals and HashCode and have the implementation style below. Appears this code is never executed.. is there any particular reason we need this code? I'm looking to simplify the classes if we can. public boolean equals(Object object) { if (!(object instanceof MyClass)) { return false; } if (this == object) { return true; } final EqualsBuilder equalsBuilder = new JAXBEqualsBuilder(); equals(object, equalsBuilder); return equalsBuilder.isEquals(); } public void hashCode(HashCodeBuilder hashCodeBuilder) { hashCodeBuilder.append(this.getValue()); hashCodeBuilder.append(this.getId()); } public int hashCode() { final HashCodeBuilder hashCodeBuilder = new JAXBHashCodeBuilder(); hashCode(hashCodeBuilder); return hashCodeBuilder.toHashCode(); }

• Include code in ASP.net

  - by Tom Gullen

  I've got an ASP.net file, and I'm trying to include dynamic code which was easy in classic ASP. Here is what I have tried so far: <%@ Register TagPrefix="TagPre" TagName="header" Src="alg/classes.aspx"%> and <!--#include file="alg/classes.aspx"--> But neither of these seem to work. The content of classes.aspx is: <script runat="server"> ' Square class Public Class square Public sqRows As Integer 'Numbers of rows this square has Public sqCols As Integer 'Number of columns this square has Public sqArray(,) As Integer 'The square array ' Initialise square array to match size of canvas Public Sub initSqArray(ByVal canvCols, ByVal canvRows) ReDim sqArray(canvCols, canvRows) sqRows = canvRows sqCols = canvCols End Sub End Class Thanks for any help!

• Accessing constructor from abstract base class with reflection

  - by craesh

  Hi! I'm playing around with Java's Reflection. I have an abstract class Base with a constructor. abstract class Base { public Base( String foo ) { // do some magic } } I have some further classes extending Base. They don't contain much logic. I want to instantiate them with Base's constructor, without having to write some proxy contructors in those derived classes. And of course, I want to instantiate those derived classes with Reflection. Say: Class cls = SomeDerivedClass.class; Constructor constr; constr = cls.getConstructor( new Class[] { String.class } ); // will return null Class clsBase = Base.class; constr = clsBase.getConstructor( new Class[] { String.class } ); // ok Base obj = (Base) constr.newInstance( new Object[] { "foo" } ); // will throw InstantiationException because it belongs to an abstract class Any ideas, how I can instantiate a derived class with Base's constructor? Or must I declare those dumb proxy constructors?

• How to inject dependencies into a custom UserNamePasswordValidator in WCF?

  - by Dannerbo

  I'm using a UserNamePasswordValidator in WCF along with Unity for my dependency injection, but since WCF creates the instance of the UserNamePasswordValidator, I cannot inject my container into the class. So how would one go about this? The simplest solution I can think of is to create a static proxy/wrapper class around a static instance of a UnityContainer, which exposes all the same methods... This way, any class can access the container, and I don't need to inject it everywhere. So I could just do UnityContainerWrapper.Resolve() anywhere in code. So basically this solution solves 2 problems for me, I can use it in classes that I'm not creating an instance of, and I can use it anywhere without having to inject the container into a bunch of classes. The only downside I can think of is that I'm now potentially exposing my container to a bunch of classes that wouldn't of had access to the container before. Not really sure if this is even a problem though?

• Add remove class?

  - by Steven

  Okay I have two classes for two links and two divs with different information. What I am trying to do is have it so when you click on one link it adds a 2 to both of the classes and makes the second div visable. When you click on the other link it takes off a 2 and makes the first div visable. Here is what I currently got $("#posts").click(function () { $("#sideboxtopleft").toggleClass("2"); $("#arrow").toggleClass("2"); }); Pretty much posts is the link, when when you click on it. It would make sideboxtopleft and arrow, sideboxtopleft2 and arrow2 and when you clicked on comments it would take off the 2 of both of those. Then there are two divs, one is set to hidden and I want to make it visable and set the other to hidden. Pretty much creating a tab system with changing tab classes.

• Linking Excel and Access

  - by Mel

  I run a sports program where i have a master roll of who is in which class in excel. I want to link this to a database in access that stores the other information about each athlete, e.g. address, parents name, school, medical details. I want to be able to add names to class in the excel speadsheet and have this automatically generate a record for that person in access. There also needs to be some failsafe for athletes that are in multiple classes. I was also doing class roles as pivot tables out of the access database so i need to code for classes and also have this allow for athletes in multiple classes/disciplines.

• Subsonic 3.0 - .Net - Error : Can not ceate an instance of an interface

  - by George

  Hi, I am new to Subsonic, I have configured Subsonic3.0 T4 Template and created classes for my project. I have taken GridView and Object Datasource. Object datasource will connect to the one of the classes which is created from subsonic. I have set object datasource for g\fetch, Insert, Update and delete methods. Then i set the datasource of grid witht he object datasource. Grid view successfully showing me all the records. But at the time of Update, Insert or delete it throws an exception that "Can not ceate an instance of an interface". And also i am not able to dwbug in the code of the subsonic. May be because of partial classes. Can anyone please let me know what is happening at the backgrund? Or may be one can give me sample example which contains subsonic 3.0 and grid add, edit and delete so it will be really helpful for me.... Please... :) Thanks, George

• mysql GROUP_CONCAT

  - by user301766

  I want to list all users with their corropsonding user class. Here are simplified versions of my tables CREATE TABLE users ( user_id INT NOT NULL AUTO_INCREMENT, user_class VARCHAR(100), PRIMARY KEY (user_id) ); INSERT INTO users VALUES (1, '1'), (2, '2'), (3, '1,2'); CREATE TABLE classes ( class_id INT NOT NULL AUTO_INCREMENT, class_name VARCHAR(100), PRIMARY KEY (class_id) ); INSERT INTO classes VALUES (1, 'Class 1'), (2, 'Class 2'); And this is the query statement I am trying to use but is only returning the first matching user class and not a concatenated list as hoped. SELECT user_id, GROUP_CONCAT(DISTINCT class_name SEPARATOR ",") AS class_name FROM users, classes WHERE user_class IN (class_id) GROUP BY user_id; Actual Output +---------+------------+ | user_id | class_name | +---------+------------+ | 1 | Class 1 | | 2 | Class 2 | | 3 | Class 1 | +---------+------------+ Wanted Output +---------+---------------------+ | user_id | class_name | +---------+---------------------+ | 1 | Class 1 | | 2 | Class 2 | | 3 | Class 1, Class 2 | +---------+---------------------+ Thanks in advance

• Java: Best practices for turning foreign horror-code into clean API...?

  - by java.is.for.desktop

  Hello, everyone! I have a project (related to graph algorithms). It is written by someone else. The code is horrible: public fields, no getters/setters huge methods, all public some classes have over 20 fields some classes have over 5 constructors (which are also huge) some of those constructors just left many fields null (so I can't make some fields final, because then every second constructor signals errors) methods and classes rely on each other in both directions I have to rewrite this into a clean and understandable API. Problem is: I myself don't understand anything in this code. Please give me hints on analyzing and understanding such code. I was thinking, perhaps, there are tools which perform static code analysis and give me call graphs and things like this.

• Error "E_UNEXPECTED(0x8000FFFF)" when using CDec/CInt/IsNumeric

  - by Marc vB

  I have encountered a strange problem, which I could solve but don't understand why it did occur. I have build a DLL with COM enabled. In this DLL I have classes that did use the functions CInt, CDec and IsNumeric. If I test these classes from a .NET application then it works ok. But when I called/run these classes from a Win32 application (with COM) then I did get an "E_UNEXPECTED(0x8000FFFF)" error. After some debugging I found out that the problem would go away if I: - replaced IsNumeric with Integer.TryParse or Decimal.TryParse - replaced CInt with Integer.Parse - replaced CDec with Decimal.Parse Can anyone explain this? Again, I could solve it by doing this but I would like to know why.

• Parsing mutiple xml files in android

  - by cppdev

  Hi, I ma writing an application where I have to parse multiple xml files as a response from a server. Till now, I have written different xml parser classes for each xml depepending on the tags present in different xmls ? Can I combine all xml parser classes and write a single xml parser that handles all different tags in different xmls ? Will it work ? Will combining xml parser classes add an overhead because xml parser will check for every tag irrespective of whether that is part of file or not ? Please help.

• Lackadaisical One-to-One between Char and Byte Streams

  - by Vaibhav Bajpai

  I expected to have a one-to-one correspondence between the character streams and byte streams in terms of how the classes are organized in their hierarchy. FilterReader and FilterWriter (character streams) correspond back to FilterInputStream and FilterOutputStream (byte stream) classes. However I noticed few changes as - BufferedInputStream extends FilterInputStream, but BufferedReader does NOT extend FilterReader. BufferedOutputStream and PrintStream both extend FilterOutputStream, but BufferedWriter and PrintWriter does NOT extend FilterWriter. FilterInputStream and FilterOutputStream are not abstract classes, but FilterReader and FilterWriter are. I am not sure if I am being too paranoid to point out such differences, but was just curious to know if there was design reasoning behind such decision.

• Why is the C# SerializedAttribute is sealed?

  - by ahmet alp balkan

  I was trying to create an attribute that implies [Serializable] but I noticed that this SerializableAttribute class is sealed. In Java it was possible to create an interface (say, MyInterface) that is inherited from Serializable interface and so all the subclasses of MyInterface would also be serializable, even its sub-sub classes would be so. Let's say I am creating an ORM and I want customers to annotate their entity classes as [DatabaseEntity] but in order to make sure that entities are serializable, I also need to ask them to attribute their classes with extra [Serializable] which does not look quite compact and neat. I am wondering why SerializableAttribute class is sealed and why has Inherited=false which implies that subclasses of serializable class will not be serializable unless it is explicitly stated. What motives are behind these design choices?

• Working with the Objective-C/Cocoa flat namespace

  - by Stephen Blinkhorn

  I've not found anything that addresses my specific name space question as yet. I am working on some AudioUnit plug-ins featuring Cocoa based GUIs. The plug-ins use a common library of user interface classes (sliders, buttons etc) which are simply added to each Xcode project. When I recompile and distribute updates it is pretty much guaranteed that at least one user interface class will have been updated since the last release. If the user launches an older plug-in before an updated plug-in then the old Cocoa classes are already loaded into the run time and the plug-in attempts to use the older implementations - often resulting in a failure one way or another. I know frameworks are the intended solution but the overhead and backwards compatibility issues are not ideal. I prefix all class names where possible but what options do I have to ensure that each plug-in contains unique class names for the shared user interface classes?

• How to better design it ???

  - by Deepak

  public interface IBasePresenter { } public interface IJobViewPresenter : IBasePresenter { } public interface IActivityViewPresenter : IBasePresenter { } public class BaseView { public IBasePresenter Presenter { get; set; } } public class JobView : BaseView { public IJobViewPresenter JobViewPresenter { get { this.Presenter as IJobViewPresenter;} } } public class ActivityView : BaseView { public IActivityViewPresenter ActivityViewPresenter { get { this.Presenter as IActivityViewPresenter;} } } Lets assume that I need a IBasePresenter property on BaseView. Now this property is inherited by JobView and ActivityView but if I need reference to IJobViewPresenter object in these derived classes then I need to type cast IBasePresenter property to IJobViewPresenter or IActivityPresenter (which I want to avoid) or create JobViewPresenter and ActivityViewPresenter on derived classes (as shown above). I want to avoid type casting in derived classes and still have reference to IJobViewPresenter or IActivityViewPresenter and still have IBasePresenter in BaseView. Is there a way I can achieve it ?

• Why are my ActiveRecord class instance variables disappearing after the first request in development

  - by Paul C

  I have a class instance variable on one of my AR classes. I set its value at boot with an initializer and, after that, never touch it again except to read from it. In development mode, this value disappears after the first request to the web server. However, when running tests, using the console or running the production server this does not happen. # The AR class class Group < ActiveRecord::Base class << self attr_accessor :path end end # The initializer Group.path = File.join(RAILS_ROOT, "public", "etc") # First request in a view %p= Group.path #=> "/home/rails/app/public/etc" # Second request in a view %p= Group.path #=> nil Is there something about development mode that nukes instance variables from classes with each request? If so, is there a way to disable this for specific variables or classes?

• StructureMap - Injecting a dependency into a base class?

  - by David

  In my domain I have a handful of "processor" classes which hold the bulk of the business logic. Using StructureMap with default conventions, I inject repositories into those classes for their various IO (databases, file system, etc.). For example: public interface IHelloWorldProcessor { string HelloWorld(); } public class HelloWorldProcessor : IHelloWorldProcessor { private IDBRepository _dbRepository; public HelloWorldProcessor(IDBRepository dbRepository) { _dbRepository = dbrepository; } public string HelloWorld(){ return _dbRepository.GetHelloWorld(); } } Now, there are some repositories that I'd like to be available to all processors, so I made a base class like this: public class BaseProcessor { protected ICommonRepository _commonRepository; public BaseProcessor(ICommonRepository commonRepository) { _commonRepository = commonRepository; } } But when my other processors inherit from it, I get a compiler error on each one saying that there's no constructor for BaseProcessor which takes zero arguments. Is there a way to do what I'm trying to do here? That is, to have common dependencies injected into a base class that my other classes can use without having to write the injections into each one?

• Need help from CSS purist!

  - by Darcy

  I'm beginning to use CSS more and more but I'm not sure if I'm using it as intended in all cases. I have classes named things like 'box' that will wrap the content inside it with a border, which seems like good CSS to me. On the other hand I have classes like 'margin-right-5' and 'float-left' that sets the css to margin-right: 5px and float:left respectively. I'm wondering if this is good practice. Then in my markup I'd do something like: <div class="box float-left margin-right-5"> <!-- CONTENT HERE --> </div> Sometimes I may want to float right or not have a margin at all and still use the 'box' class, so I use several classes in order to make the css more flexible. Am I destroying the principles of CSS?

• Using ASP.NET Session for Lifetime Management (Unity)

  - by Sigray

  I am considering using Unity to manage the lifetime of a custom user class instance. I am planning on extending the LifetimeManager with a custom ASP.NET session manager. What I want to be able to do is store and retrieve the currently logged in user object from my custom classes, and have Unity get the instance of User from the session object in ASP.NET, or (when in a Win32 project) retrieve it statically or from the current thread. So far my best solution is to create a static instance of my Unity container on startup, and use the Resolve method to get my User object from each of my classes. However, this seems to create a dependency on the unity container in my other classes. What is the more "Unity" way of accomplishing this goal? I would like to be able to read/replace the current User instance from any class.

• What are some useful SQL statements that should be known by all developers who may touch the Back en

  - by Jian Lin

  What are some useful SQL statements that should be known by all developers who may touch the Back end side of the project? (Update: just like in algorithm, we know there are sorting problems, shuffling problems, and we know some solutions to them. This question is aiming at the same thing). For example, ones I can think of are: Get a list of Employees and their boss. Or one with the employee's salary greater than the boss. (Self-join) Get a list of the most popular Classes registered by students, from the greatest number to the smallest. (Count, group by, order by) Get a list of Classes that are not registered by any students. (Outer join and check whether the match is NULL, or by Get from Classes table, all ClassIDs which are NOT IN (a subquery to get all ClassIDs from the Registrations table)) Are there some SQL statements that should be under the sleeve of all developers that might touch back end data?
