  • Parsing Range Expressions

    - by sameer karjatkar
    I have a string (R(46 - 9900)) AND ( NOT (R(48 - 9900))) where R denotes Range . If you evaluate the expression it results in R(46-47) , considering the logical operators (AND,NOT). I have a requirement where I need to parse such a string and evaluate it to a correct result . I have to use C++ as a programming tool to achieve this result . Can anyone suggest a few guide lines as to how do I proceed on this ?

    Hi, We have request from our clients to provide a POS terminal version of our web-based software. They want to be able to enter record to their database from POS terminal (via web service) instead of using PC browser. I am the one to develop this application, as I am the lead developer of the main application. I haven't done any Windows embedded programming or .net compact edition before and would appreciate link to good tutorial or info on how to start developing for Windows CE 6.0 enabled POS terminal or device.

  • How to pipe the output of a command to file on Linux

    - by morpheous
    I am running a task on the CLI, which prompts me for a yes/no. After selecting a choice, a vast amount of info scrolls on the screen - including several errors. I want to pipe the output to a file so I can see the errors - but a simple '' is not working since the command expects a keyboar input. i am running on Ubuntu 9.1

  • Rails 3 Initializers: No such file to load

    - by waveslider
    I am trying to use the Sunlight API gem with a Rails project. I have installed the gem and can successfully use it from irb. However, when I put the require statement (require 'sunlight') in sunlight.rb in config/initializers, I get the following error: /opt/local/lib/ruby/gems/1.8/gems/activesupport-3.0.0.beta3/lib/active_support/dependencies.rb:209:in `require': no such file to load -- sunlight (LoadError) I checked the permissions on the gems directory, and it is world readable/executable. Here is the code from sunlight.rb: require 'rubygems' require 'sunlight' Sunlight::Base.api_key = 'bb7b775755054c54aa9715d202f6785c'

  • JPA - Can I create an Entity class, using an @DiscriminatorValue, that doesn't have its own table?

    - by DaveyDaveDave
    Hi - this is potentially a bit complex, so I'll do my best to describe my situation - it's also my first post here, so please forgive formatting mistakes, etc! I'm using JPA with joined inheritance and a database structure that looks like: ACTION --------- ACTION_ID ACTION_MAPPING_ID ACTION_TYPE DELIVERY_CHANNEL_ACTION -------------------------- ACTION_ID CHANNEL_ID OVERRIDE_ADDRESS_ACTION -------------------------- ACTION_ID (various fields specific to this action type) So, in plain English, I have multiple different types of action, all share an ACTION_MAPPING, which is referenced from the 'parent' ACTION table. DELIVERY_CHANNEL_ACTION and OVERRIDE_ADDRESS_ACTION both have extra, supplementary data of their own, and are mapped to ACTION with a FK. Real-world, I also have a 'suppress' action, but this doesn't have any supplementary data of its own, so it doesn't have a corresponding table - all it needs is an ACTION_MAPPING, which is stored in the ACTION table. Hopefully you're with me so far... I'm creating a new project from scratch, so am pretty flexible in what I can do, but obviously would like to get it right from the outset! My current implementation, which works, has three entities loosely defined as follows: @Entity @Table(name="ACTION") @Inheritance(strategy=InheritanceType.JOINED) @DiscriminatorValue("SUPPRESS") public class Action @Entity @Table(name="DELIVERY_CHANNEL_ACTION") @DiscriminatorValue("DELIVERY_CHANNEL") public class DeliveryChannelAction extends Action @Entity @Table(name="OVERRIDE_ADDRESS_ACTION") @DiscriminatorValue("OVERRIDE_ADDRESS") public class OverrideAddressAction extends Action That is - I have a concrete base class, Action, with a Joined inheritance strategy. DeliveryChannelAction and OverrideAddressAction both extend Action. What feels wrong here though, is that my Action class is the base class for these two actions, but also forms the concrete implementation for the suppress action. For the time being this works, but at some point more actions are likely to be added, and there's every chance that some of them will, like SUPPRESS, have no supplementary data, which will start to get difficult! So... what I would like to do, in the object model world, is to have Action be abstract, and create a SuppressAction class, which is empty apart from having a @DiscriminatorValue("SUPPRESS"). I've tried doing exactly what is described above, so, changing Action to: @Entity @Table(name="ACTION") @Inheritance(strategy=InheritanceType.JOINED) public abstract class Action and creating: @DiscriminatorValue("SUPPRESS") public class SuppressAction extends Action but no luck - it seems to work fine for DeliveryChannelAction and OverrideAddressAction, but when I try to create a SuppressAction and persist it, I get: java.lang.IllegalArgumentException: Object: com.mypackage.SuppressAction[actionId=null] is not a known entity type. at org.eclipse.persistence.internal.sessions.UnitOfWorkImpl.registerNewObjectForPersist(UnitOfWorkImpl.java:4147) at org.eclipse.persistence.internal.jpa.EntityManagerImpl.persist(EntityManagerImpl.java:368) at com.mypackage.test.util.EntityTestUtil.createSuppressAction(EntityTestUtil.java:672) at com.mypackage.entities.ActionTest.testCRUDAction(ActionTest.java:27) which I assume is down to the fact that SuppressAction isn't registered as an entity, but I don't know how I can do that, given that it doesn't have an associated table. Any pointers, either complete answers or hints for things to Google (I'm out of ideas!), most welcome :) EDIT: to correct my stacktrace.

  • Explaining your system to a client

    - by Sir Graystar
    I'm currently developing a small Database Management System for a local company. How would you go about explaining how the system you have designed to a client? If they are non-technical and have no understanding of programming, how would you go about showing what the system will do and how it will do it? I guess some sort of visual representation of the system but this seems very patronising to me.

  • Anchor Window to Screen Edges in WPF

    - by Kirk
    I've decided to teach myself C# by writing a music player in Visual Studio 2010. I went with WPF because from what I hear it sounds like it will be a good base to skin from. I want to program my window with the behavior where if the window comes to the edge of a screen (within 10px or so) it will snap to the screen edge. What's the best way to go about this?

  • what is the purpose of getEventType() method in XMLStreamReader Class

    - by KItis
    I have sample code written for parsing xml file using javax.xml package. it uses the method called getEventType() , but I can not understand the purpose of this method. i wrote simple application to understand its usefulness, but it output only some random numbers for which I can not make any sense, could some one help me to get this point right. Here is the sample code I have written. public List parseXML(File f) throws XMLStreamException{ xmlInputFactory = new WstxInputFactory(); xmlInputFactory.setProperty(XMLInputFactory2.IS_REPLACING_ENTITY_REFERENCES, Boolean.FALSE); xmlInputFactory.setProperty(XMLInputFactory2.IS_SUPPORTING_EXTERNAL_ENTITIES, Boolean.FALSE); xmlInputFactory.setProperty(XMLInputFactory2.IS_COALESCING,Boolean.FALSE); xmlInputFactory.setProperty(XMLInputFactory2.IS_VALIDATING,Boolean.FALSE); xmlInputFactory.configureForSpeed(); List<Task> tasks = new LinkedList<Task>(); //xmlStreamReader = xmlInputFactory.createXMLStreamReader(new StringReader(dmml)); xmlStreamReader = xmlInputFactory.createXMLStreamReader(f); int eventType = xmlStreamReader.getEventType(); eventType = xmlStreamReader.next(); System.out.println(eventType); eventType = xmlStreamReader.next(); System.out.println(eventType); eventType = xmlStreamReader.next(); System.out.println(eventType); eventType = xmlStreamReader.next(); System.out.println(eventType); eventType = xmlStreamReader.next(); System.out.println(eventType); eventType = xmlStreamReader.next(); System.out.println(eventType); eventType = xmlStreamReader.next(); System.out.println(eventType); eventType = xmlStreamReader.next(); System.out.println(eventType); eventType = xmlStreamReader.next(); System.out.println(eventType); eventType = xmlStreamReader.next(); System.out.println(eventType); eventType = xmlStreamReader.next(); System.out.println(eventType); /*String currentElement = ""; String currentElementText = ""; }

  • Auto discover projects in continous integration Tools

    - by vmiazzo
    We have a code base composed of many projects. Currently each time we add a project on SVN we must reconfigure CruiseControl to start build and test on such project. I'm looking for a tool (better if open source) able to scan the SVN repository and find new projects by itself. A project can be "a SVN folder containing trunk, tags, branches subfolders". Even better if the tool supports multistaged continous integration and build on demand. Thanks

  • Is it possible to use components derived from TWinControl in a service?

    - by M Schenkel
    I am creating a Delphi service. Is there any way to use controls derived from TWinControl within services? Ultimately the control and any controls I place on it will be saved to a bitmap. But anything I try I get "control has no parent window" error. I have successfully created a TBitMap and can accomplish the same functionality. But having all the functionality built into the VCL would greatly simplify the task.

  • Where can I find Python tutorials aimed at people who are already programmers?

    - by Chris R
    I'm a reasonably skilled programmer, and I'm interested in branching out into some new languages -- python, specifically -- but frankly I do NOT want to go through a tutorial that assumes I know nothing about programming. I want a tutorial -- again, preferably for python -- that assumes I'm just unfamiliar with the language itself and describes the ways I can use the language to solve problems. Does such a beast exist? I mean, other than the Python wiki?

  • Add a List<object> to EF

    - by Billdr
    I'm playing around with EF, trying to get my bearings. Right now I'm writing a blackjack game for a website. The problem is that my whenever I pull a GameState from the database, the playerHand, dealerHand, theDeck, and dealerHidden properties are null. public class GameState { [Key] [DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)] public int gameSession { get; set; } public int playerScore { get; set; } public int dealerScore { get; set; } public Deck theDeck { get; set; } public List<Cards> playerHand { get; set; } public List<Cards> dealerHand { get; set; } public Cards dealerHidden { get; set; } public bool gameOver { get; set; } } public class Cards { [Key] [DatabaseGenerated(DatabaseGeneratedOption.Identity)] public int cardId { get; set; } public string cardName { get; set; } public int cardValue { get; set; } } public class GameStateContext : DbContext { public GameStateContext() : base("MyContext") { } protected override void OnModelCreating(DbModelBuilder modelBuilder) { modelBuilder.Entity<GameState>().HasRequired(e => e.theDeck); modelBuilder.Entity<GameState>().HasRequired(e => e.dealerHand).WithMany().WillCascadeOnDelete(false); modelBuilder.Entity<GameState>().HasRequired(e => e.playerHand).WithMany().WillCascadeOnDelete(false); modelBuilder.Entity<GameState>().HasOptional(e => e.dealerHidden); modelBuilder.Entity<Deck>().HasRequired(e => e.cards).WithMany().WillCascadeOnDelete(false); base.OnModelCreating(modelBuilder); } public DbSet<GameState> GameStates { get; set; } public DbSet<Deck> Decks { get; set; } public DbSet<Card> Cards { get; set; } } The cards and deck table are populated. Where am I going wrong?

  • Query performs poorly unless a temp table is used

    - by Paul McLoughlin
    The following query takes about 1 minute to run, and has the following IO statistics: SELECT T.RGN, T.CD, T.FUND_CD, T.TRDT, SUM(T2.UNITS) AS TotalUnits FROM dbo.TRANS AS T JOIN dbo.TRANS AS T2 ON T2.RGN=T.RGN AND T2.CD=T.CD AND T2.FUND_CD=T.FUND_CD AND T2.TRDT<=T.TRDT JOIN TASK_REQUESTS AS T3 ON T3.CD=T.CD AND T3.RGN=T.RGN AND T3.TASK = 'UPDATE_MEM_BAL' GROUP BY T.RGN, T.CD, T.FUND_CD, T.TRDT (4447 row(s) affected) Table 'TRANSACTIONS'. Scan count 5977, logical reads 7527408, physical reads 0, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0. Table 'TASK_REQUESTS'. Scan count 1, logical reads 11, physical reads 0, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0. SQL Server Execution Times: CPU time = 58157 ms, elapsed time = 61437 ms. If I instead introduce a temporary table then the query returns quickly and performs less logical reads: CREATE TABLE #MyTable(RGN VARCHAR(20) NOT NULL, CD VARCHAR(20) NOT NULL, PRIMARY KEY([RGN],[CD])); INSERT INTO #MyTable(RGN, CD) SELECT RGN, CD FROM TASK_REQUESTS WHERE TASK='UPDATE_MEM_BAL'; SELECT T.RGN, T.CD, T.FUND_CD, T.TRDT, SUM(T2.UNITS) AS TotalUnits FROM dbo.TRANS AS T JOIN dbo.TRANS AS T2 ON T2.RGN=T.RGN AND T2.CD=T.CD AND T2.FUND_CD=T.FUND_CD AND T2.TRDT<=T.TRDT JOIN #MyTable AS T3 ON T3.CD=T.CD AND T3.RGN=T.RGN GROUP BY T.RGN, T.CD, T.FUND_CD, T.TRDT (4447 row(s) affected) Table 'Worktable'. Scan count 5974, logical reads 382339, physical reads 0, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0. Table 'TRANSACTIONS'. Scan count 4, logical reads 4547, physical reads 0, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0. Table '#MyTable________________________________________________________________000000000013'. Scan count 1, logical reads 2, physical reads 0, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0. SQL Server Execution Times: CPU time = 1420 ms, elapsed time = 1515 ms. The interesting thing for me is that the TASK_REQUEST table is a small table (3 rows at present) and statistics are up to date on the table. Any idea why such different execution plans and execution times would be occuring? And ideally how to change things so that I don't need to use the temp table to get decent performance? The only real difference in the execution plans is that the temp table version introduces an index spool (eager spool) operation.
