• Android SQLite Problem: Program Crash When Try a Query!

  - by Skatephone

  Hi i have a problem programming with android SDK 1.6. I'm doing the same things of the "notepad exaple" but the programm crash when i try some query. If i try to do a query directly in to the DatabaseHelper create() metod it goes, but out of this function it doesn't. Do you have any idea? this is the source: public class DbAdapter { public static final String KEY_NAME = "name"; public static final String KEY_TOT_DAYS = "totdays"; public static final String KEY_ROWID = "_id"; private static final String TAG = "DbAdapter"; private DatabaseHelper mDbHelper; private SQLiteDatabase mDb; private static final String DATABASE_NAME = "flowratedb"; private static final String DATABASE_TABLE = "girl_data"; private static final String DATABASE_TABLE_2 = "girl_cyle"; private static final int DATABASE_VERSION = 2; /** * Database creation sql statement */ private static final String DATABASE_CREATE = "create table "+DATABASE_TABLE+" (id integer, name text not null, totdays int);"; private static final String DATABASE_CREATE_2 = "create table "+DATABASE_TABLE_2+" (ref_id integer, day long not null);"; private final Context mCtx; private static class DatabaseHelper extends SQLiteOpenHelper { DatabaseHelper(Context context) { super(context, DATABASE_NAME, null, DATABASE_VERSION); } @Override public void onCreate(SQLiteDatabase db) { db.execSQL(DATABASE_CREATE); db.execSQL(DATABASE_CREATE_2); db.delete(DATABASE_TABLE, null, null); db.delete(DATABASE_TABLE_2, null, null); } @Override public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { Log.w(TAG, "Upgrading database from version " + oldVersion + " to " + newVersion + ", which will destroy all old data"); db.execSQL("DROP TABLE IF EXISTS "+DATABASE_TABLE); db.execSQL("DROP TABLE IF EXISTS "+DATABASE_TABLE_2); onCreate(db); } } public DbAdapter(Context ctx) { this.mCtx = ctx; } public DbAdapter open() throws SQLException { mDbHelper = new DatabaseHelper(mCtx); mDb = mDbHelper.getWritableDatabase(); return this; } public void close() { mDbHelper.close(); } public long createGirl(int id,String name, int totdays) { ContentValues initialValues = new ContentValues(); initialValues.put(KEY_ROWID, id); initialValues.put(KEY_NAME, name); initialValues.put(KEY_TOT_DAYS, totdays); return mDb.insert(DATABASE_TABLE, null, initialValues); } public long createGirl_fd_day(int refid, long fd) { ContentValues initialValues = new ContentValues(); initialValues.put("ref_id", refid); initialValues.put("calendar", fd); return mDb.insert(DATABASE_TABLE, null, initialValues); } public boolean updateGirl(int rowId, String name, int totdays) { ContentValues args = new ContentValues(); args.put(KEY_NAME, name); args.put(KEY_TOT_DAYS, totdays); return mDb.update(DATABASE_TABLE, args, KEY_ROWID + "=" + rowId, null) > 0; } public boolean deleteGirlsData() { if (mDb.delete(DATABASE_TABLE_2, null, null)>0) if(mDb.delete(DATABASE_TABLE, null, null)>0) return true; return false; } public Bundle fetchAllGirls() { Bundle extras = new Bundle(); Cursor cur = mDb.query(DATABASE_TABLE, new String[] {KEY_ROWID, KEY_NAME, KEY_TOT_DAYS}, null, null, null, null, null); cur.moveToFirst(); int tot = cur.getCount(); extras.putInt("tot", tot); int index; for (int i=0;i<tot;i++){ index=cur.getInt(cur.getColumnIndex("_id")); extras.putString("name"+index, cur.getString(cur.getColumnIndex("name"))); extras.putInt("totdays"+index, cur.getInt(cur.getColumnIndex("totdays"))); } cur.close(); return extras; } public Cursor fetchGirl(int rowId) throws SQLException { Cursor mCursor = mDb.query(true, DATABASE_TABLE, new String[] {KEY_ROWID, KEY_NAME, KEY_TOT_DAYS}, KEY_ROWID + "=" + rowId, null, null, null, null, null); if (mCursor != null) { mCursor.moveToFirst(); } return mCursor; } public Cursor fetchGirlCD(int rowId) throws SQLException { Cursor mCursor = mDb.query(true, DATABASE_TABLE_2, new String[] {"ref_id", "day"}, "ref_id=" + rowId, null, null, null, null, null); if (mCursor != null) { mCursor.moveToFirst(); } return mCursor; } } Tank's Valerio From Italy :)

• Arraylist is null; I cannot access books in the arraylist

  - by user3701380

  I am a beginner-intermediate java programmer and I am getting a null pointer exception from my arraylist. I am writing a bookstore program for APCS and when i add the book, it is supposed to add to the arraylist in the inventory class. But when i call a method to search for a book (e.g. by title), it shows that there isn't anything in the arraylist. //Here is my inventory class -- it has all methods for adding the book or searching for one The searching methods are in getBookByTitle, getBookByAuthor, and getBookByISBN and the method for adding a book is addBook package webbazonab; //Inventory Class //Bharath Senthil //Ansh Sikka import java.util.ArrayList; public class Inventory{ private ArrayList<Book> allBooks = new ArrayList<Book>(); private String bookTitles; private String bookAuthors; private String bookPrices; private String bookCopies; private String ISBNs; public Inventory() { } //@param double price, int copies, String bookTitle, String Author, String isbnNumber public void addBooks(Book addedBook){ allBooks.add(addedBook); } public boolean isAvailable(){ for(Book myBook : allBooks){ if(myBook.copiesLeft() == 0) return false; } return true; } public String populateTitle(){ for (Book titleBooks : allBooks){ bookTitles = titleBooks.getTitle() + "\n"; return bookTitles; } return bookTitles; } public String populateAuthor(){ for(Book authorBooks : allBooks){ bookAuthors = authorBooks.getAuthor() + "\n"; return bookAuthors; } return bookAuthors; } public String populatePrice(){ for (Book pricedBooks : allBooks){ bookPrices = String.valueOf(pricedBooks.getPrice()) + "\n"; } return "$" + bookPrices; } /** * * @return */ public String populateCopies(){ for (Book amtBooks : allBooks){ bookCopies = String.valueOf(amtBooks.copiesLeft()) + "\n"; return bookCopies; } return bookCopies; } public String populateISBN(){ for (Book isbnNums : allBooks){ ISBNs = isbnNums.getIsbn() + "\n"; return ISBNs; } return ISBNs; } @SuppressWarnings("empty-statement") public Book getBookByTitle(String titleSearch) { for(Book titleBook : allBooks) { if (titleBook.getTitle().equals(titleSearch)) { return titleBook; } } return null; } public Book getBookByISBN(String isbnSearch){ for(Book isbnBookSearches : allBooks){ if(isbnBookSearches.getIsbn().equals(isbnSearch)){ return isbnBookSearches; } } return null; } public Book getBookByAuthor(String authorSearch){ for(Book authorBookSearches : allBooks){ if(authorBookSearches.getAuthor().equals(authorSearch)){ return authorBookSearches; } } return null; } public void sort(){ for(int i = 0; i < allBooks.size(); i++) { for(int k = 0; k < allBooks.size(); k++) { if(((Book) allBooks.get(i)).getIsbn().compareTo(((Book) allBooks.get(k)).getIsbn()) < 1) { Book temp = (Book) allBooks.get(k); allBooks.set(k, allBooks.get(i)); allBooks.set(i, temp); } else if(((Book) allBooks.get(i)).getIsbn().compareTo(((Book) allBooks.get(k)).getIsbn()) > 1) { Book temp = (Book) allBooks.get(i); allBooks.set(i, allBooks.get(k)); allBooks.set(k, temp); } } } } public ArrayList<Book> getBooks(){ return allBooks; } } //The exception occurs when i call the method here (in another class): Inventory lib = new Inventory(); jTextField12.setText(lib.getBookByAuthor(authorSearch).getTitle()); Here is my book class if you need it package webbazonab; //Webbazon AB //Project By: Ansh Sikka and Bharath Senthil public class Book { private double myPrice; private String myTitle; private String bookAuthor; private String isbn; private int myCopies; public Book(double price, int copies, String bookTitle, String Author, String isbnNumber) { myPrice = price; myCopies = copies; myTitle = bookTitle; bookAuthor = Author; isbn = isbnNumber; } public double getPrice() { return myPrice; } public String getIsbn() { return isbn; } public String getTitle() { return myTitle; } public String getAuthor() { return bookAuthor; } public int copiesLeft(){ return myCopies; } public String notFound(){ return "The book you searched for could not be found!"; } public String toString() { return "Title: " + getTitle() + "\nAuthor: " + getAuthor() + "\nNumber of Available Books: " + copiesLeft() + "\nPrice: $" + getPrice(); } } Thanks!

• Performance of delegate and method group

  - by BlueFox

  Hi I was investigating the performance hit of creating Cachedependency objects, so I wrote a very simple test program as follows: using System; using System.Collections.Generic; using System.Diagnostics; using System.Web.Caching; namespace Test { internal class Program { private static readonly string[] keys = new[] {"Abc"}; private static readonly int MaxIteration = 10000000; private static void Main(string[] args) { Debug.Print("first set"); test7(); test6(); test5(); test4(); test3(); test2(); Debug.Print("second set"); test2(); test3(); test4(); test5(); test6(); test7(); } private static void test2() { DateTime start = DateTime.Now; var list = new List<CacheDependency>(); for (int i = 0; i < MaxIteration; i++) { list.Add(new CacheDependency(null, keys)); } Debug.Print("test2 Time: " + (DateTime.Now - start)); } private static void test3() { DateTime start = DateTime.Now; var list = new List<Func<CacheDependency>>(); for (int i = 0; i < MaxIteration; i++) { list.Add(() => new CacheDependency(null, keys)); } Debug.Print("test3 Time: " + (DateTime.Now - start)); } private static void test4() { var p = new Program(); DateTime start = DateTime.Now; var list = new List<Func<CacheDependency>>(); for (int i = 0; i < MaxIteration; i++) { list.Add(p.GetDep); } Debug.Print("test4 Time: " + (DateTime.Now - start)); } private static void test5() { var p = new Program(); DateTime start = DateTime.Now; var list = new List<Func<CacheDependency>>(); for (int i = 0; i < MaxIteration; i++) { list.Add(() => { return p.GetDep(); }); } Debug.Print("test5 Time: " + (DateTime.Now - start)); } private static void test6() { DateTime start = DateTime.Now; var list = new List<Func<CacheDependency>>(); for (int i = 0; i < MaxIteration; i++) { list.Add(GetDepSatic); } Debug.Print("test6 Time: " + (DateTime.Now - start)); } private static void test7() { DateTime start = DateTime.Now; var list = new List<Func<CacheDependency>>(); for (int i = 0; i < MaxIteration; i++) { list.Add(() => { return GetDepSatic(); }); } Debug.Print("test7 Time: " + (DateTime.Now - start)); } private CacheDependency GetDep() { return new CacheDependency(null, keys); } private static CacheDependency GetDepSatic() { return new CacheDependency(null, keys); } } } But I can't understand why these result looks like this: first set test7 Time: 00:00:00.4840277 test6 Time: 00:00:02.2041261 test5 Time: 00:00:00.1910109 test4 Time: 00:00:03.1401796 test3 Time: 00:00:00.1820105 test2 Time: 00:00:08.5394884 second set test2 Time: 00:00:07.7324423 test3 Time: 00:00:00.1830105 test4 Time: 00:00:02.3561347 test5 Time: 00:00:00.1750100 test6 Time: 00:00:03.2941884 test7 Time: 00:00:00.1850106 In particular: 1. Why is test4 and test6 much slower than their delegate version? I also noticed that Resharper specifically has a comment on the delegate version suggesting change test5 and test7 to "Covert to method group". Which is the same as test4 and test6 but they're actually slower? 2. I don't seem a consistent performance difference when calling test4 and test6, shouldn't static calls to be always faster?

• Animation issue caused by C# parameters passed by reference rather than value, but where?

  - by Jordan Roher

  I'm having trouble with sprite animation in XNA that appears to be caused by a struct passed as a reference value. But I'm not using the ref keyword anywhere. I am, admittedly, a C# noob, so there may be some shallow bonehead error in here, but I can't see it. I'm creating 10 ants or bees and animating them as they move across the screen. I have an array of animation structs, and each time I create an ant or bee, I send it the animation array value it requires (just [0] or [1] at this time). Deep inside the animation struct is a timer that is used to change frames. The ant/bee class stores the animation struct as a private variable. What I'm seeing is that each ant or bee uses the same animation struct, the one I thought I was passing in and copying by value. So during Update(), when I advance the animation timer for each ant/bee, the next ant/bee has its animation timer advanced by that small amount. If there's 1 ant on screen, it animates properly. 2 ants, it runs twice as fast, and so on. Obviously, not what I want. Here's an abridged version of the code. How is BerryPicking's ActorAnimationGroupData[] getting shared between the BerryCreatures? class BerryPicking { private ActorAnimationGroupData[] animations; private BerryCreature[] creatures; private Dictionary<string, Texture2D> creatureTextures; private const int maxCreatures = 5; public BerryPickingExample() { this.creatures = new BerryCreature[maxCreatures]; this.creatureTextures = new Dictionary<string, Texture2D>(); } public void LoadContent() { // Returns data from an XML file Reader reader = new Reader(); animations = reader.LoadAnimations(); CreateCreatures(); } // This is called from another function I'm not including because it's not relevant to the problem. // In it, I remove any creature that passes outside the viewport by setting its creatures[] spot to null. // Hence the if(creatures[i] == null) test is used to recreate "dead" creatures. Inelegant, I know. private void CreateCreatures() { for (int i = 0; i < creatures.Length; i++) { if (creatures[i] == null) { // In reality, the name selection is randomized creatures[i] = new BerryCreature("ant"); // Load content and texture (which I create elsewhere) creatures[i].LoadContent( FindAnimation(creatures[i].Name), creatureTextures[creatures[i].Name]); } } } private ActorAnimationGroupData FindAnimation(string animationName) { int yourAnimation = -1; for (int i = 0; i < animations.Length; i++) { if (animations[i].name == animationName) { yourAnimation = i; break; } } return animations[yourAnimation]; } public void Update(GameTime gameTime) { for (int i = 0; i < creatures.Length; i++) { creatures[i].Update(gameTime); } } } class Reader { public ActorAnimationGroupData[] LoadAnimations() { ActorAnimationGroupData[] animationGroup; XmlReader file = new XmlTextReader(filename); // Do loading... // Then later file.Close(); return animationGroup; } } class BerryCreature { private ActorAnimation animation; private string name; public BerryCreature(string name) { this.name = name; } public void LoadContent(ActorAnimationGroupData animationData, Texture2D sprite) { animation = new ActorAnimation(animationData); animation.LoadContent(sprite); } public void Update(GameTime gameTime) { animation.Update(gameTime); } } class ActorAnimation { private ActorAnimationGroupData animation; public ActorAnimation(ActorAnimationGroupData animation) { this.animation = animation; } public void LoadContent(Texture2D sprite) { this.sprite = sprite; } public void Update(GameTime gameTime) { animation.Update(gameTime); } } struct ActorAnimationGroupData { // There are lots of other members of this struct, but the timer is the only one I'm worried about. // TimerData is another struct private TimerData timer; public ActorAnimationGroupData() { timer = new TimerData(2); } public void Update(GameTime gameTime) { timer.Update(gameTime); } } struct TimerData { public float currentTime; public float maxTime; public TimerData(float maxTime) { this.currentTime = 0; this.maxTime = maxTime; } public void Update(GameTime gameTime) { currentTime += (float)gameTime.ElapsedGameTime.TotalSeconds; if (currentTime >= maxTime) { currentTime = maxTime; } } }

• How to implement an EventHandler to update controls

  - by Bill

  May I ask for help with the following? I am attempting to connect and control three pieces of household electronic equipment by computer through a GlobalCache GC-100 and iTach. As you will see in the following code, I created a class-instance of GlobalCacheAdapter that communicates with each piece of equipment. Although the code seems to work well in controlling the equipment, I am having trouble updating controls with the feedback from the equipment. The procedure "ReaderThreadProc" captures the feedback; however I don't know how to update the associated TextBox with the feedback. I believe that I need to create an EventHandler to notify the TextBox of the available update; however I am uncertain as to how an EventHandler like this would be implemented. Any help wold be greatly appreciated. using System; using System.IO; using System.Net; using System.Net.Sockets; using System.Threading; using System.Windows.Forms; namespace WindowsFormsApplication1 { public partial class Form1 : Form { // Create three new instances of GlobalCacheAdaptor and connect. // GC-100 (Elan) 192.168.1.70 4998 // GC-100 (TuneSuite) 192.168.1.70 5000 // GC iTach (Lighting) 192.168.1.71 4999 private GlobalCacheAdaptor elanGlobalCacheAdaptor; private GlobalCacheAdaptor tuneSuiteGlobalCacheAdaptor; private GlobalCacheAdaptor lutronGlobalCacheAdaptor; public Form1() { InitializeComponent(); elanGlobalCacheAdaptor = new GlobalCacheAdaptor(); elanGlobalCacheAdaptor.ConnectToDevice(IPAddress.Parse("192.168.1.70"), 4998); tuneSuiteGlobalCacheAdaptor = new GlobalCacheAdaptor(); tuneSuiteGlobalCacheAdaptor.ConnectToDevice(IPAddress.Parse("192.168.1.70"), 5000); lutronGlobalCacheAdaptor = new GlobalCacheAdaptor(); lutronGlobalCacheAdaptor.ConnectToDevice(IPAddress.Parse("192.168.1.71"), 4999); elanTextBox.Text = elanGlobalCacheAdaptor._line; tuneSuiteTextBox.Text = tuneSuiteGlobalCacheAdaptor._line; lutronTextBox.Text = lutronGlobalCacheAdaptor._line; } private void btnZoneOnOff_Click(object sender, EventArgs e) { elanGlobalCacheAdaptor.SendMessage("sendir,4:3,1,40000,4,1,21,181,21,181,21,181,21,181,21,181,21,181,21,181,21,181,21,181,21,181,21,181,21,800" + Environment.NewLine); } private void btnSourceInput1_Click(object sender, EventArgs e) { elanGlobalCacheAdaptor.SendMessage("sendir,4:3,1,40000,1,1,20,179,20,179,20,179,20,179,20,179,20,179,20,179,20,278,20,179,20,179,20,179,20,780" + Environment.NewLine); } private void btnSystemOff_Click(object sender, EventArgs e) { elanGlobalCacheAdaptor.SendMessage("sendir,4:3,1,40000,1,1,20,184,20,184,20,184,20,184,20,184,20,286,20,286,20,286,20,184,20,184,20,184,20,820" + Environment.NewLine); } private void btnLightOff_Click(object sender, EventArgs e) { lutronGlobalCacheAdaptor.SendMessage("sdl,14,0,0,S2\x0d"); } private void btnLightOn_Click(object sender, EventArgs e) { lutronGlobalCacheAdaptor.SendMessage("sdl,14,100,0,S2\x0d"); } private void btnChannel31_Click(object sender, EventArgs e) { tuneSuiteGlobalCacheAdaptor.SendMessage("\xB8\x4D\xB5\x33\x31\x00\x30\x21\xB8\x0D"); } private void btnChannel30_Click(object sender, EventArgs e) { tuneSuiteGlobalCacheAdaptor.SendMessage("\xB8\x4D\xB5\x33\x30\x00\x30\x21\xB8\x0D"); } } } public class GlobalCacheAdaptor { public Socket _multicastListener; public string _preferredDeviceID; public IPAddress _deviceAddress; public Socket _deviceSocket; public StreamWriter _deviceWriter; public bool _isConnected; public int _port; public IPAddress _address; public string _line; public GlobalCacheAdaptor() { } public static readonly GlobalCacheAdaptor Instance = new GlobalCacheAdaptor(); public bool IsListening { get { return _multicastListener != null; } } public GlobalCacheAdaptor ConnectToDevice(IPAddress address, int port) { if (_deviceSocket != null) _deviceSocket.Close(); try { _port = port; _address = address; _deviceSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); _deviceSocket.Connect(new IPEndPoint(address, port)); ; _deviceAddress = address; var stream = new NetworkStream(_deviceSocket); var reader = new StreamReader(stream); var writer = new StreamWriter(stream) { NewLine = "\r", AutoFlush = true }; _deviceWriter = writer; writer.WriteLine("getdevices"); var readerThread = new Thread(ReaderThreadProc) { IsBackground = true }; readerThread.Start(reader); _isConnected = true; return Instance; } catch { DisconnectFromDevice(); MessageBox.Show("ConnectToDevice Error."); throw; } } public void SendMessage(string message) { try { var stream = new NetworkStream(_deviceSocket); var reader = new StreamReader(stream); var writer = new StreamWriter(stream) { NewLine = "\r", AutoFlush = true }; _deviceWriter = writer; writer.WriteLine(message); var readerThread = new Thread(ReaderThreadProc) { IsBackground = true }; readerThread.Start(reader); } catch { MessageBox.Show("SendMessage() Error."); } } public void DisconnectFromDevice() { if (_deviceSocket != null) { try { _deviceSocket.Close(); _isConnected = false; } catch { MessageBox.Show("DisconnectFromDevice Error."); } _deviceSocket = null; } _deviceWriter = null; _deviceAddress = null; } private void ReaderThreadProc(object state) { var reader = (StreamReader)state; try { while (true) { var line = reader.ReadLine(); if (line == null) break; _line = _line + line + Environment.NewLine; } // Need to create EventHandler to notify the TextBoxes to update with _line } catch { MessageBox.Show("ReaderThreadProc Error."); } } }

• Why SELECT N + 1 with no foreign keys and LINQ?

  - by Daniel Flöijer

  I have a database that unfortunately have no real foreign keys (I plan to add this later, but prefer not to do it right now to make migration easier). I have manually written domain objects that map to the database to set up relationships (following this tutorial http://www.codeproject.com/Articles/43025/A-LINQ-Tutorial-Mapping-Tables-to-Objects), and I've finally gotten the code to run properly. However, I've noticed I now have the SELECT N + 1 problem. Instead of selecting all Product's they're selected one by one with this SQL: SELECT [t0].[id] AS [ProductID], [t0].[Name], [t0].[info] AS [Description] FROM [products] AS [t0] WHERE [t0].[id] = @p0 -- @p0: Input Int (Size = -1; Prec = 0; Scale = 0) [65] Controller: public ViewResult List(string category, int page = 1) { var cat = categoriesRepository.Categories.SelectMany(c => c.LocalizedCategories).Where(lc => lc.CountryID == 1).First(lc => lc.Name == category).Category; var productsToShow = cat.Products; var viewModel = new ProductsListViewModel { Products = productsToShow.Skip((page - 1) * PageSize).Take(PageSize).ToList(), PagingInfo = new PagingInfo { CurrentPage = page, ItemsPerPage = PageSize, TotalItems = productsToShow.Count() }, CurrentCategory = cat }; return View("List", viewModel); } Since I wasn't sure if my LINQ expression was correct I tried to just use this but I still got N+1: var cat = categoriesRepository.Categories.First(); Domain objects: [Table(Name = "products")] public class Product { [Column(Name = "id", IsPrimaryKey = true, IsDbGenerated = true, AutoSync = AutoSync.OnInsert)] public int ProductID { get; set; } [Column] public string Name { get; set; } [Column(Name = "info")] public string Description { get; set; } private EntitySet<ProductCategory> _productCategories = new EntitySet<ProductCategory>(); [System.Data.Linq.Mapping.Association(Storage = "_productCategories", OtherKey = "productId", ThisKey = "ProductID")] private ICollection<ProductCategory> ProductCategories { get { return _productCategories; } set { _productCategories.Assign(value); } } public ICollection<Category> Categories { get { return (from pc in ProductCategories select pc.Category).ToList(); } } } [Table(Name = "products_menu")] class ProductCategory { [Column(IsPrimaryKey = true, Name = "products_id")] private int productId; private EntityRef<Product> _product = new EntityRef<Product>(); [System.Data.Linq.Mapping.Association(Storage = "_product", ThisKey = "productId")] public Product Product { get { return _product.Entity; } set { _product.Entity = value; } } [Column(IsPrimaryKey = true, Name = "products_types_id")] private int categoryId; private EntityRef<Category> _category = new EntityRef<Category>(); [System.Data.Linq.Mapping.Association(Storage = "_category", ThisKey = "categoryId")] public Category Category { get { return _category.Entity; } set { _category.Entity = value; } } } [Table(Name = "products_types")] public class Category { [Column(Name = "id", IsPrimaryKey = true, IsDbGenerated = true, AutoSync = AutoSync.OnInsert)] public int CategoryID { get; set; } private EntitySet<ProductCategory> _productCategories = new EntitySet<ProductCategory>(); [System.Data.Linq.Mapping.Association(Storage = "_productCategories", OtherKey = "categoryId", ThisKey = "CategoryID")] private ICollection<ProductCategory> ProductCategories { get { return _productCategories; } set { _productCategories.Assign(value); } } public ICollection<Product> Products { get { return (from pc in ProductCategories select pc.Product).ToList(); } } private EntitySet<LocalizedCategory> _LocalizedCategories = new EntitySet<LocalizedCategory>(); [System.Data.Linq.Mapping.Association(Storage = "_LocalizedCategories", OtherKey = "CategoryID")] public ICollection<LocalizedCategory> LocalizedCategories { get { return _LocalizedCategories; } set { _LocalizedCategories.Assign(value); } } } [Table(Name = "products_types_localized")] public class LocalizedCategory { [Column(Name = "id", IsPrimaryKey = true, IsDbGenerated = true, AutoSync = AutoSync.OnInsert)] public int LocalizedCategoryID { get; set; } [Column(Name = "products_types_id")] private int CategoryID; private EntityRef<Category> _Category = new EntityRef<Category>(); [System.Data.Linq.Mapping.Association(Storage = "_Category", ThisKey = "CategoryID")] public Category Category { get { return _Category.Entity; } set { _Category.Entity = value; } } [Column(Name = "country_id")] public int CountryID { get; set; } [Column] public string Name { get; set; } } I've tried to comment out everything from my View, so nothing there seems to influence this. The ViewModel is as simple as it looks, so shouldn't be anything there. When reading this ( http://www.hookedonlinq.com/LinqToSQL5MinuteOVerview.ashx) I started suspecting it might be because I have no real foreign keys in the database and that I might need to use manual joins in my code. Is that correct? How would I go about it? Should I remove my mapping code from my domain model or is it something that I need to add/change to it? Note: I've stripped parts of the code out that I don't think is relevant to make it cleaner for this question. Please let me know if something is missing.

• How to make code run a certain amount of times before returning something?

  - by user3564967

  I made a trivia game and I have to make a method (SuccessOrFail) that will return whether the user beat the trivia or not. namespace D4 { /// <summary> /// Displays the trivia and returns whether the user succeeded or not, number of questions asked, and a free piece of trivia. /// </summary> public partial class TriviaForm : Form { private Trivia trivia; private Question question; private Random rand = new Random(); private HashSet<int> pickedQuestion = new HashSet<int>(); private string usersAnswer; private int numCorrectAnswers; private int numIncorrectAnswers; public TriviaForm() { InitializeComponent(); this.trivia = new Trivia(); QuestionRandomizer(); QuestionOutputter(); } /// <summary> /// This method will return true if succeeded or false if not. /// </summary> /// <returns>Whether the user got the trivia right or not</returns> public bool SuccessOrFail(bool wumpus) { bool successOrFail = false; int maxQuestions = 3; if (wumpus == true) maxQuestions = 5; int numNeededCorrect = maxQuestions / 2 + 1; if (this.usersAnswer == question.CorrectAnswer.ToString()) numCorrectAnswers++; else numIncorrectAnswers++; if (numCorrectAnswers + numIncorrectAnswers == maxQuestions) { if (numCorrectAnswers == numNeededCorrect) successOrFail = true; else successOrFail = false; numCorrectAnswers = 0; numIncorrectAnswers = 0; return successOrFail; } else return false; } /// <summary> /// This method will output a free answer to the player. /// </summary> public string FreeTrivia() { return question.Freetrivia; } // This method tells the player whether they were correct or not. private void CorrectOrNot() { if (this.usersAnswer == question.CorrectAnswer.ToString()) MessageBox.Show("Correct"); else MessageBox.Show("Incorrect"); } // Displays the questions and answers on the form. private void QuestionOutputter() { this.txtQuestion.Text = question.QuestionText; this.txtBox0.Text = question.Answers[0]; this.txtBox1.Text = question.Answers[1]; this.txtBox2.Text = question.Answers[2]; this.txtBox3.Text = question.Answers[3]; } // Clears the TextBoxes and displays a new random question. private void btnNext_Click(object sender, EventArgs e) { this.usersAnswer = txtAnswer.Text; CorrectOrNot(); this.txtQuestion.Clear(); this.txtBox0.Clear(); this.txtBox1.Clear(); this.txtBox2.Clear(); this.txtBox3.Clear(); this.txtAnswer.Clear(); this.txtAnswer.Focus(); QuestionRandomizer(); QuestionOutputter(); this.txtsuc.Text = SuccessOrFail(false).ToString(); } // Choose a random number and assign the corresponding data to question, refreshes the list if all questions used. private void QuestionRandomizer() { if (pickedQuestion.Count < trivia.AllQuestions.Count) { int random; do { random = rand.Next(trivia.AllQuestions.Count); } while (pickedQuestion.Contains(random)); pickedQuestion.Add(random); this.question = trivia.AllQuestions.ToArray()[random]; if (pickedQuestion.Count == trivia.AllQuestions.ToArray().Length) pickedQuestion.Clear(); } } } } My question is how to make it so that the code asks the user 3 or 5 questions and then returns whether the user won or not? I was wondering if somehow I could make a public void that would just make the form pop up and ask the user 3 to 5 questions and then once it asks the maximum number of questions, to close and then have a method that returns true if the user won, or false if they didn't. But I literally have no idea how to do that. Edit: So I know a for loop can make code run more than once. But the problem I'm having is, is that I don't know how to make it so that the trivia game asks 3 to 5 questions BEFORE returning something.

• Android Video Camera : still picture

  - by Alex

  I use the camera intent to capture video. Here is the problem: If I use this line of code, I can record video. But onActivityResult doesn't work. Intent intent = new Intent("android.media.action.VIDEO_CAMERA"); If I use this line of code, after press the recording button, the camera is freezed, I mean, the picture is still. Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE); BTW, when I use $Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); to capture a picture, it works fine. The java file is as follows: package com.camera.picture; import java.io.File; import java.text.SimpleDateFormat; import java.util.Date; import android.app.Activity; import android.content.ContentValues; import android.content.Intent; import android.net.Uri; import android.os.Bundle; import android.os.Environment; import android.provider.MediaStore; import android.util.Log; import android.view.View; import android.widget.Button; import android.widget.ImageView; import android.widget.Toast; import android.widget.VideoView; public class PictureCameraActivity extends Activity { private static final int IMAGE_CAPTURE = 0; private static final int VIDEO_CAPTURE = 1; private Button startBtn; private Button videoBtn; private Uri imageUri; private Uri videoUri; private ImageView imageView; private VideoView videoView; /** Called when the activity is first created. * sets the content and gets the references to * the basic widgets on the screen like * {@code Button} or {@link ImageView} */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); imageView = (ImageView)findViewById(R.id.img); videoView = (VideoView)findViewById(R.id.videoView); startBtn = (Button) findViewById(R.id.startBtn); startBtn.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { startCamera(); } }); videoBtn = (Button) findViewById(R.id.videoBtn); videoBtn.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub startVideoCamera(); } }); } public void startCamera() { Log.d("ANDRO_CAMERA", "Starting camera on the phone..."); String fileName = "testphoto.jpg"; ContentValues values = new ContentValues(); values.put(MediaStore.Images.Media.TITLE, fileName); values.put(MediaStore.Images.Media.DESCRIPTION, "Image capture by camera"); values.put(MediaStore.Images.Media.MIME_TYPE, "image/jpeg"); imageUri = getContentResolver().insert( MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values); Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri); intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1); startActivityForResult(intent, IMAGE_CAPTURE); } protected void onActivityResult(int requestCode, int resultCode, Intent data) { if (requestCode == IMAGE_CAPTURE) { if (resultCode == RESULT_OK){ Log.d("ANDROID_CAMERA","Picture taken!!!"); imageView.setImageURI(imageUri); } } if (requestCode == VIDEO_CAPTURE) { if (resultCode == RESULT_OK) { Log.d("ANDROID_CAMERA","Video taken!!!"); Toast.makeText(this, "Video saved to:\n" + data.getData(), Toast.LENGTH_LONG).show(); videoView.setVideoURI(videoUri); } } } private void startVideoCamera() { // TODO Auto-generated method stub //create new Intent Log.d("ANDRO_CAMERA", "Starting camera on the phone..."); String fileName = "testvideo.mp4"; ContentValues values = new ContentValues(); values.put(MediaStore.Video.Media.TITLE, fileName); values.put(MediaStore.Video.Media.DESCRIPTION, "Video captured by camera"); values.put(MediaStore.Video.Media.MIME_TYPE, "video/mp4"); videoUri = getContentResolver().insert( MediaStore.Video.Media.EXTERNAL_CONTENT_URI, values); Intent intent = new Intent("android.media.action.VIDEO_CAMERA"); //Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE); intent.putExtra(MediaStore.EXTRA_OUTPUT, videoUri); intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1); // start the Video Capture Intent startActivityForResult(intent, VIDEO_CAPTURE); } private static File getOutputMediaFile() { // TODO Auto-generated method stub // To be safe, you should check that the SDCard is mounted // using Environment.getExternalStorageState() before doing this.

• Sharing disk volumes across OpenVZ guests to reduce Package Management Overhead

  - by andyortlieb

  Is it feasible to create a single "master" OpenVZ guest who would only be used for package management, and use something like mount --bind on several other OpenVZ guests sort of trick them into using the environment installed by the master guest? The point of this would be so that users can maintain their own containers, and yet stay in sync with the master development environment, so they'll always have the latest & greatest requirements without worrying too much about system administration. If they need to install their own packages, could put them in /opt, or /usr/local (or set a path to their home directory)? To rephrase, I would like several (developer's, for example) OpenVZ guests whose /bin, /usr (and so on...) actually refer to the same disk location as that of a master OpenVZ guest who can be started up to install and update common packages for the environment to be shared by all of this group of OpenVZ guests. For what it's worth, we're running Debian 6. Edit: I have tried mounting (bind, and readonly) /bin, /lib, /sbin, /usr in this fashion and it refuses to start the containers stating that files are already mounted or otherwise in use: Starting container ... vzquota : (error) Quota on syscall for id 1102: Device or resource busy vzquota : (error) Possible reasons: vzquota : (error) - Container's root is already mounted vzquota : (error) - there are opened files inside Container's private area vzquota : (error) - your current working directory is inside Container's vzquota : (error) private area vzquota : (error) Currently used file(s): /var/lib/vz/private/1102/sbin /var/lib/vz/private/1102/usr /var/lib/vz/private/1102/lib /var/lib/vz/private/1102/bin vzquota on failed [3] If I unmount these four volumes, and start the guest, and then mount them after the guest has started, the guest never sees them mounted.

• Remotely viewing IP camera on Belkin N450 DB router

  - by Mike Miller

  I need to setup a wireless IP camera (Trendnet TV-IP501W) on my network so that it is remotely visible from anywhere. Right now I successfully connected it to my home network but nothing else. My router is a Belkin N450 DB. Any help would be much appreciated, including what this would be referred to as so I could more easily ask another forum. I believe it is something like "port forwarding" but I'm not sure. Ok, I believe I found this in the "virtual servers" section. It asks for enabling with a check box, description, inbound port, type, private IP, & private port. In that order I have checked enabling, "camera", 150, TCP, 81, and 81? I'm assuming inbound ports are the numbers I use for the home network - xxx.xxx.x.150 and the 81 was for private. I used my WAN IP and added :81 and .81 but didn't get it. What am I doing wrong?

• Server.transfer causing HttpException

  - by salvationishere

  I am developing a C#/SQL ASP.NET web application in VS 2008. Currently I am using the Server.Transfer method to transfer control from one ASPX.CS file to another ASPX file. The first time through, this works. But after control is transferred to this new file it encounters a condition: if (restart == false) { where "restart" is a boolean variable. After this statement it immediately transfers control back to the same ASPX.CS file and tries to reexecute the Server.Transfer method. This time it gives me the following exception and stack trace. Do you know what is causing this? I tried to read this but it didn't make much sense to me. System.Web.HttpException was unhandled by user code Message="Error executing child request for DataMatch.aspx."

• trouble running smooth animation in thread only when using key listener

  first time using a forum for coding help so sorry if i post this all wrong. i have more than a few classes i don't think screenManger or core holds the problem but i included them just incase. i got most of this code working through a set of tutorials. but a certain point started trying to do more on my own. i want to play the animation only when i'm moving my sprite. in my KeyTest class i am using threads to run the animation it used to work (poorly) but now not at all pluss it really gunks up my computer. i think it's because of the thread. im new to threads so i'm not to sure if i should even be using one in this situation or if its dangerous for my computer. the animation worked smoothly when i had the sprite bouce around the screen forever. the animation loop played with out stopping. i think the main problem is between the animationThread, Sprite, and keyTest classes, but itcould be more indepth. if someone could point me in the right direction for making the animation run smoothly when i push down a key and stop runing when i let off it would be greatly apriciated. i already looked at this Java a moving animation (sprite) obviously we were doing the same tutorial. but i feel my problem is slightly different. p.s. sorry for the typos. import java.awt.*;

• How to make Shared Keys .ssh/authorized_keys and sudo work together?

  - by farinspace

  I've setup the .ssh/authorized_keys and am able to login with the new "user" using the pub/private key ... I have also added "user" to the sudoers list ... the problem I have now is when I try to execute a sudo command, something simple like: $ sudo cd /root it will prompt me for my password, which I enter, but it doesn't work (I am using the private key password I set) Also, ive disabled the users password using $ passwd -l user What am I missing? Somewhere my initial remarks are being misunderstood ... I am trying to harden my system ... the ultimate goal is to use pub/private keys to do logins versus simple password authentication. I've figured out how to set all that up via the authorized_keys file. Additionally I will ultimately prevent server logins through the root account. But before I do that I need sudo to work for a second user (the user which I will be login into the system with all the time). For this second user I want to prevent regular password logins and force only pub/private key logins, if I don't lock the user via" passwd -l user ... then if i dont use a key, i can still get into the server with a regular password. But more importantly I need to get sudo to work with a pub/private key setup with a user whos had his/her password disabled. Edit: Ok I think I've got it (the solution): 1) I've adjusted /etc/ssh/sshd_config and set PasswordAuthentication no This will prevent ssh password logins (be sure to have a working public/private key setup prior to doing this 2) I've adjusted the sudoers list visudo and added root ALL=(ALL) ALL dimas ALL=(ALL) NOPASSWD: ALL 3) root is the only user account that will have a password, I am testing with two user accounts "dimas" and "sherry" which do not have a password set (passwords are blank, passwd -d user) The above essentially prevents everyone from logging into the system with passwords (a public/private key must be setup). Additionally users in the sudoers list have admin abilities. They can also su to different accounts. So basically "dimas" can sudo su sherry, however "dimas can NOT do su sherry. Similarly any user NOT in the sudoers list can NOT do su user or sudo su user. NOTE The above works but is considered poor security. Any script that is able to access code as the "dimas" or "sherry" users will be able to execute sudo to gain root access. A bug in ssh that allows remote users to log in despite the settings, a remote code execution in something like firefox, or any other flaw that allows unwanted code to run as the user will now be able to run as root. Sudo should always require a password or you may as well log in as root instead of some other user.

• can't send with postfix but I can whith one user

  I have a postfix and dovecot server but when i try to send an email i get an time -out. Im trying to send with the email [email protected]. A telnet session isn't helping much ether. I get a blank screen. Local it's working fine. My smtp service is running on treadity.com:25. The strange thing is that the logs are completely empty with any info regarding sending emails.

• cakephp & nginx config/rewrite rules

  - by seanl

  Hi somebody please help me out, I've asked this at stackoverflow as well but not got much of a response and was debating whether it was programming or server related. I’m trying to setup a cakephp environment on a Centos server running Nginx with Fact CGI. I already have a wordpress site running on the server and a phpmyadmin site so I have PHP configured correctly. My problem is that I cannot get the rewrite rules setup correct in my vhost so that cake renders pages correctly i.e. with styling and so on. I’ve googled as much as possible and the main consensus from the sites like the one listed below is that I need to have the following rewrite rule in place location / { root /var/www/sites/somedomain.com/current; index index.php index.html; # If the file exists as a static file serve it # directly without running all # the other rewrite tests on it if (-f $request_filename) { break; } if (!-f $request_filename) { rewrite ^/(.+)$ /index.php?url=$1 last; break; } } http://blog.getintheloop.eu/2008/4/17/nginx-engine-x-rewrite-rules-for-cakephp problem is these rewrite assume you run cake directly out of the webroot which is not what I want to do. I have a standard setup for each site i.e. one folder per site containing the following folders log, backup, private and public. Public being where nginx is looking for its files to serve but I have cake installed in private with a symlink in public linking back to /private/cake/ this is my vhost server { listen 80; server_name app.domain.com; access_log /home/public_html/app.domain.com/log/access.log; error_log /home/public_html/app.domain.com/log/error.log; #configure Cake app to run in a sub-directory #Cake install is not in root, but elsewhere and configured #in APP/webroot/index.php** location /home/public_html/app.domain.com/private/cake { index index.php; if (!-e $request_filename) { rewrite ^/(.+)$ /home/public_html/app.domain.com/private/cake/$1 last; break; } } location /home/public_html/app.domain.com/private/cake/ { index index.php; if (!-e $request_filename) { rewrite ^/(.+)$ /home/public_html/app.domain.com/public/index.php?url=$1 last; break; } } # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000 location ~ \.php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /home/public_html/app.domain.com/private/cake$fastcgi_script_name; include /etc/nginx/fastcgi_params; } } Now like I said I can see the main index.php of cake and have connected it to my DB but this page is without styling so before I proceed any further I would like to configure it correctly. What am I doing wrong………. Thanks seanl

• Silverlight child windows in MVVM pattern

  - by rrejc

  Hello, I am trying to find the right way to get the data from a ChildWindow/popup using a MVVM pattern in Silverlight (3). For example: I have a main page with a data entry form and I want to open a popup with a list of customers. When user selects a customer I want to transfer selected customer into the main page. This is what the (example) code which I am using at the moment: Main page public partial class MainPage : UserControl { public MainPageViewModel ViewModel { get; private set; } public MainPage() { InitializeComponent(); ViewModel = new MainPageViewModel(); DataContext = ViewModel; } private void SearchCustomer_Click(object sender, RoutedEventArgs e) { ViewModel.SearchCustomer(); } } public class MainPageViewModel: ViewModel { private string customer; public string Customer { get { return customer; } set { customer = value; RaisePropertyChanged("Customer"); } } public void SearchCustomer() { // Called from a view SearchWindow searchWindow = new SearchWindow(); searchWindow.Closed += (sender, e) => { if ((bool)searchWindow.DialogResult) { Customer = searchWindow.ViewModel.SelectedCustomer.ToString(); } }; searchWindow.Show(); } } Child window public partial class SearchWindow : ChildWindow { public SearchWindowViewModel ViewModel { get; private set; } public SearchWindow() { InitializeComponent(); ViewModel = new SearchWindowViewModel(); DataContext = ViewModel; } private void OKButton_Click(object sender, RoutedEventArgs e) { DialogResult = ViewModel.OkButtonClick(); } private void CancelButton_Click(object sender, RoutedEventArgs e) { DialogResult = ViewModel.CancelButtonClick(); } } public class SearchWindowViewModel: ViewModel { private Customer selectedCustomer; private ObservableCollection<Customer> customers; public ObservableCollection<Customer> Customers { get { return customers; } set {customers = value; RaisePropertyChanged("Customers"); } } public Customer SelectedCustomer { get { return selectedCustomer; } set { selectedCustomer = value; RaisePropertyChanged("SelectedCustomer"); } } public SearchWindowViewModel() { Customers = new ObservableCollection<Customer>(); ISearchService searchService = new FakeSearchService(); foreach (Customer customer in searchService.FindCustomers("dummy")) Customers.Add(customer); } public bool? OkButtonClick() { if (SelectedCustomer != null) return true; else return null; // show some error message before that } public bool? CancelButtonClick() { return false; } } Is this the right way or is there anything more "simple"? Cheers, Rok

Question 1: Why servlet can`t inject jms resources when they use static declaration ? @Resource(mappedName = "jms/Tarturus") private static ConnectionFactory connectionFactory; @Resource(mappedName = "jms/StyxMDB") private static Queue queue; private Connection connection; and @PostConstruct public void postConstruct() { try { connection = connectionFactory.createConnection(); } catch (JMSException e) { e.printStackTrace(); } } @PreDestroy public void preDestroy() { try { connection.close(); } catch (JMSException e) { e.printStackTrace(); } } The error that I get is : [#|2010-05-03T15:18:17.118+0300|WARNING|glassfish3.0|javax.enterprise.system.container.web.com.sun.enterprise.web|_ThreadID=35;_ThreadName=Thread-1;|StandardWrapperValve[WorkerServlet]: PWC1382: Allocate exception for servlet WorkerServlet com.sun.enterprise.container.common.spi.util.InjectionException: Error creating managed object for class ua.co.rufous.server.services.WorkerServiceImpl at com.sun.enterprise.container.common.impl.util.InjectionManagerImpl.createManagedObject(InjectionManagerImpl.java:312) at com.sun.enterprise.web.WebContainer.createServletInstance(WebContainer.java:709) at com.sun.enterprise.web.WebModule.createServletInstance(WebModule.java:1937) at org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.java:1252) Caused by: com.sun.enterprise.container.common.spi.util.InjectionException: Exception attempting to inject Unresolved Message-Destination-Ref ua.co.rufous.server.services.WorkerServiceImpl/[email protected]@null into class ua.co.rufous.server.services.WorkerServiceImpl at com.sun.enterprise.container.common.impl.util.InjectionManagerImpl._inject(InjectionManagerImpl.java:614) at com.sun.enterprise.container.common.impl.util.InjectionManagerImpl.inject(InjectionManagerImpl.java:384) at com.sun.enterprise.container.common.impl.util.InjectionManagerImpl.injectInstance(InjectionManagerImpl.java:141) at com.sun.enterprise.container.common.impl.util.InjectionManagerImpl.injectInstance(InjectionManagerImpl.java:127) at com.sun.enterprise.container.common.impl.util.InjectionManagerImpl.createManagedObject(InjectionManagerImpl.java:306) ... 27 more Caused by: com.sun.enterprise.container.common.spi.util.InjectionException: Illegal use of static field private static javax.jms.Queue ua.co.rufous.server.services.WorkerServiceImpl.queue on class that only supports instance-based injection at com.sun.enterprise.container.common.impl.util.InjectionManagerImpl._inject(InjectionManagerImpl.java:532) ... 31 more |#] my MDB : /** * asadmin commands * asadmin create-jms-resource --restype javax.jms.ConnectionFactory jms/Tarturus * asadmin create-jms-resource --restype javax.jms.Queue jms/StyxMDB * asadmin list-jms-resources */ @MessageDriven(mappedName = "jms/StyxMDB", activationConfig = { @ActivationConfigProperty(propertyName = "connectionFactoryJndiName", propertyValue = "jms/Tarturus"), @ActivationConfigProperty(propertyName = "acknowledgeMode", propertyValue = "Auto-acknowledge"), @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue") }) public class StyxMDB implements MessageListener { @EJB private ActivationProcessingLocal aProcessing; public StyxMDB() { } public void onMessage(Message message) { try { TextMessage msg = (TextMessage) message; String hash = msg.getText(); GluttonyLogger.getInstance().writeInfoLog("geted jms message hash = " + hash); } catch (JMSException e) { } } } everything work good without static declaration: @Resource(mappedName = "jms/Tarturus") private ConnectionFactory connectionFactory; @Resource(mappedName = "jms/StyxMDB") private Queue queue; private Connection connection; Question 2: what is the best practice for working with MDB : processing full request in onMessage() or calling another bean(Stateless bean in my case) in onMessage() method that would process it. Processing including few calls to soap services, so the full processing time could be for a 3 seconds. Thank you.

• Android strange behavior with listview and custom cursor adapter

  - by Michael Little

  I have a problem with a list view and a custom cursor adapter and I just can't seem to figure out what is wrong with my code. Basically, in my activity I call initalize() that does a bunch of stuff to handle getting the proper data and initializing the listview. On first run of the activity you can see from the images that one of the items is missing from the list. If I go to another activity and go back to this activity the item that was missing shows up. I believe it has something to do with setContentView(R.layout.parent). If I move that to my initialize() then the item never shows up even when returning from another activity. So, for some reason, returning from another activity bypasses setContentView(R.layout.parent) and everything works fine. I know it's impossible for me to bypass setContentView(R.layout.parent) so I need to figure out what the problem is. Also, I did not include the layout because it is nothing more then two textviews. Also, the images I have attached do not show that the missing item is the last one on the list. Custom Cursor Adapter: public class CustomCursorAdapter extends SimpleCursorAdapter { private Context context; private int layout; public CustomCursorAdapter (Context context, int layout, Cursor c, String[] from, int[] to) { super(context, layout, c, from, to); this.context = context; this.layout = layout; } public View newView(Context context, Cursor cursor, ViewGroup parent) { LayoutInflater inflater = LayoutInflater.from(context); final View view = inflater.inflate(layout, parent, false); return view; } @Override public void bindView(View v, Context context, Cursor c) { if (c.getColumnName(0).matches("section")){ int nameCol = c.getColumnIndex("section"); String section = c.getString(nameCol); TextView section_text = (TextView) v.findViewById(R.id.text1); if ((section.length() > 0)) { section_text.setText(section); } else { //so we don't have an empty spot section_text.setText(""); section_text.setVisibility(2); section_text.setHeight(1); } } else if (c.getColumnName(0).matches("code")) { int nameCol = c.getColumnIndex("code"); String mCode = c.getString(nameCol); TextView code_text = (TextView) v.findViewById(R.id.text1); if (code_text != null) { int i = 167; byte[] data = {(byte) i}; String strSymbol = EncodingUtils.getString(data, "windows-1252"); mCode = strSymbol + " " + mCode; code_text.setText(mCode); code_text.setSingleLine(); } } if (c.getColumnName(1).matches("title")){ int nameCol = c.getColumnIndex("title"); String mTitle = c.getString(nameCol); TextView title_text = (TextView) v.findViewById(R.id.text2); if (title_text != null) { title_text.setText(mTitle); } } else if (c.getColumnName(1).matches("excerpt")) { int nameCol = c.getColumnIndex("excerpt"); String mExcerpt = c.getString(nameCol); TextView excerpt_text = (TextView) v.findViewById(R.id.text2); if (excerpt_text != null) { excerpt_text.setText(mExcerpt); excerpt_text.setSingleLine(); } } } The Activity: public class parent extends ListActivity { private static String[] TITLE_FROM = { SECTION, TITLE, _ID, }; private static String[] CODE_FROM = { CODE, EXCERPT, _ID, }; private static String ORDER_BY = _ID + " ASC"; private static int[] TO = { R.id.text1, R.id.text2, }; String breadcrumb = null; private MyData data; private SQLiteDatabase db; CharSequence parent_id = ""; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); data = new MyData(this); db = data.getReadableDatabase();

if (bun == null) { //this is the first run tvBreadCrumb.setText(null); tvBreadCrumb.setHeight(0); parent_id = "0"; try { Cursor cursor = getData(parent_id); showSectionData(cursor); } finally { data.close(); } } else { CharSequence state = bun.getString("state"); breadcrumb = bun.getString("breadcrumb"); tvBreadCrumb.setText(breadcrumb); CharSequence code = bun.getString("code"); parent_id = code; if (state.equals("chapter")) { try { Cursor cursor = getData(parent_id); showSectionData(cursor); } finally { data.close(); } } else if (state.equals("code")) { try { Cursor cursor = getCodeData(parent_id); showCodeData(cursor); } finally { data.close(); } } } } @Override public void onStart() { //initialize(); super.onResume(); } @Override public void onResume() { initialize(); super.onResume(); } private Cursor getData(CharSequence parent_id) { Cursor cTitles = db.query(TITLES_TABLE_NAME, TITLE_FROM, "parent_id = " + parent_id, null, null, null, ORDER_BY);

CharSequence intent = bun.getString("intent"); if (intent != null) { Cursor cursor1 = ((CursorAdapter)getListAdapter()).getCursor(); startManagingCursor(cursor1); TextView tvBreadCrumb; tvBreadCrumb = (TextView)findViewById(R.id.breadcrumb);
