  • SyntaxHighlighter and Line Break Tags

    - by azamsharp
    I am using the following syntax highligher: http://alexgorbatchev.com/wiki/SyntaxHighlighter For some reason when it encounter <br> it simply prints out <br> tags. I cannot replace the whole thing with System.Environment.NewLine since it will mess up the complete description. Here is my code: public static string GetDescription(string description) { string codeStartPattern = "&lt;code&gt;"; string codeEndPattern = "&lt;/code&gt;"; Regex reg = new Regex(codeStartPattern); description = reg.Replace(description, ReplaceWithStartDiv); reg = new Regex(codeEndPattern); description = reg.Replace(description, ReplaceWithEndDiv); return description; } private static string ReplaceWithStartDiv(Match m) { return "<script type='syntaxhighlighter' class='brush: csharp'><![CDATA["; } private static string ReplaceWithEndDiv(Match m) { return "]]></script>"; } I guess I only need to replace <br> with System.Environment.Newline with the code that is between the <code> snippet here </code> Thanks!

  • Generate a Version.java file in Maven

    - by Ralph
    I have a Java project that I build using an Ant script. I am trying to convert the project to Maven. One of the tasks generates a Java source file called Version.java that contains a static String representation of the compilation timestamp, as follows: package com.foo.bar; public final class Version { public static String VERSION="100301.1046"; } The Ant task is very simple: <target name="version" depends="init" description="Create Version.java"> <echo file="src/${package.dir}/Version.java" message="package ${package.name};${line.separator}" /> <echo file="src/${package.dir}/Version.java" append="true" message="public final class Version {${line.separator}" /> <echo file="src/${package.dir}/Version.java" append="true" message=" public static String VERSION=&quot;${buildtime}&quot;;${line.separator}" /> <echo file="src/${package.dir}/Version.java" append="true" message="}${line.separator}" /> <echo message="BUILD ${buildtime}" /> </target> Is it possible to do something similar in Maven, using generate-sources, or some other simple method?

  • Will Delphi be there in future ?

    - by devdude
    Yes, there is a version 2009. I know Delphi has a big community since years (10 plus)and I believe you could create native windows exe before Visual Basic got to speed (with all its dll's nighmare). But is it future-proof ? Is there a need or market for a non-crossplatform native all-in-one executable ? Will Embarcardero ex Codegear ex Borland continue to push it ? Why is it so expensive ? Who (non company) can afford it, in order to learn it ?

  • iPhone and Core Data: how to retain user-entered data between updates?

    - by Shaggy Frog
    Consider an iPhone application that is a catalogue of animals. The application should allow the user to add custom information for each animal -- let's say a rating (on a scale of 1 to 5), as well as some notes they can enter in about the animal. However, the user won't be able to modify the animal data itself. Assume that when the application gets updated, it should be easy for the (static) catalogue part to change, but we'd like the (dynamic) custom user information part to be retained between updates, so the user doesn't lose any of their custom information. We'd probably want to use Core Data to build this app. Let's also say that we have a previous process already in place to read in animal data to pre-populate the backing (SQLite) store that Core Data uses. We can embed this database file into the application bundle itself, since it doesn't get modified. When a user downloads an update to the application, the new version will include the latest (static) animal catalogue database, so we don't ever have to worry about it being out of date. But, now the tricky part: how do we store the (dynamic) user custom data in a sound manner? My first thought is that the (dynamic) database should be stored in the Documents directory for the app, so application updates don't clobber the existing data. Am I correct? My second thought is that since the (dynamic) user custom data database is not in the same store as the (static) animal catalogue, we can't naively make a relationship between the Rating and the Notes entities (in one database) and the Animal entity (in the other database). In this case, I would imagine one solution would be to have an "animalName" string property in the Rating/Notes entity, and match it up at runtime. Is this the best way to do it, or is there a way to "sync" two different databases in Core Data?

  • simple Java "service provider frameworks"?

    - by Jason S
    I refer to "service provider framework" as discussed in Chapter 2 of Effective Java, which seems like exactly the right way to handle a problem I am having, where I need to instantiate one of several classes at runtime, based on a String to select which service, and an Configuration object (essentially an XML snippet): But how do I get the individual service providers (e.g. a bunch of default providers + some custom providers) to register themselves? interface FooAlgorithm { /* methods particular to this class of algorithms */ } interface FooAlgorithmProvider { public FooAlgorithm getAlgorithm(Configuration c); } class FooAlgorithmRegistry { private FooAlgorithmRegistry() {} static private final Map<String, FooAlgorithmProvider> directory = new HashMap<String, FooAlgorithmProvider>(); static public FooAlgorithmProvider getProvider(String name) { return directory.get(serviceName); } static public boolean registerProvider(String name, FooAlgorithmProvider provider) { if (directory.containsKey(name)) return false; directory.put(name, provider); return true; } } e.g. if I write custom classes MyFooAlgorithm and MyFooAlgorithmProvider to implement FooAlgorithm, and I distribute them in a jar, is there any way to get registerProvider to be called automatically, or will my client programs that use the algorithm have to explicitly call FooAlgorithmRegistry.registerProvider() for each class they want to use?

  • Learning Hibernate: too many connections

    - by stivlo
    I'm trying to learn Hibernate and I wrote the simplest Person Entity and I was trying to insert 2000 of them. I know I'm using deprecated methods, I will try to figure out what are the new ones later. First, here is the class Person: @Entity public class Person { private int id; private String name; @Id @GeneratedValue(strategy = GenerationType.TABLE, generator = "person") @TableGenerator(name = "person", table = "sequences", allocationSize = 1) public int getId() { return id; } public void setId(int id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } } Then I wrote a small App class that insert 2000 entities with a loop: public class App { private static AnnotationConfiguration config; public static void insertPerson() { SessionFactory factory = config.buildSessionFactory(); Session session = factory.getCurrentSession(); session.beginTransaction(); Person aPerson = new Person(); aPerson.setName("John"); session.save(aPerson); session.getTransaction().commit(); } public static void main(String[] args) { config = new AnnotationConfiguration(); config.addAnnotatedClass(Person.class); config.configure("hibernate.cfg.xml"); //is the default already new SchemaExport(config).create(true, true); //print and execute for (int i = 0; i < 2000; i++) { insertPerson(); } } } What I get after a while is: Exception in thread "main" org.hibernate.exception.JDBCConnectionException: Cannot open connection Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Too many connections Now I know that probably if I put the transaction outside the loop it would work, but mine was a test to see what happens when executing multiple transactions. And since there is only one open at each time, it should work. I tried to add session.close() after the commit, but I got Exception in thread "main" org.hibernate.SessionException: Session was already closed So how to solve the problem?

  • Detecting bad jpeg images

    - by Gerard Cerchio
    The question on validating jpegs on network transfer is very helpful. Could we take this question one step further? What if the image data is incomplete or corrupt from the server? The complete transport works, the MIME type is image/jpeg, the UIImage is constructed and non-nil but the renderer discovers inconsistencies in the data and the log shows "Bad Huffman code" or "premature end of data segment" How would I capture this error before tossing the UIImage into the view context and thereby getting a not-pretty image on the screen? Could I render it to a non-screen context and capture the error?

  • WCF, 4.0, Bidirectional...

    - by TomTom
    ...what options are there now with .NET 4.0, in a way that does support NAT for the client side (i.e. client behind NAT). I would prefer to use something HTTP based, but that is a weak condition - I think mid term I will have some non http communication outside WCF anyway, so proxy traversal is something I could delay. Pre .NET 4.0 there was the issue that basically the server-client channel would be opened from the server, which made NAT something non-traversable. Polling is not acceptable - we talk time sensitive information here. So, what are my options now?

  • A regex for version number parsing

    - by ajborley
    Hi, I have a version number of the following form: version.release.modification where version, release and modification are either a set of digits or the '*' wildcard character. Additionally, any of these numbers (and any preceding .) may be missing. So the following are valid and parse as: 1.23.456 = version 1, release 23, modification 456 1.23 = version 1, release 23, any modification 1.23.* = version 1, release 23, any modification 1.* = version 1, any release, any modification 1 = version 1, any release, any modification * = any version, any release, any modification But these are not valid: *.12 *123.1 12* 12.*.34 Can anyone provide me a not-too-complex regex to validate and retrieve the release, version and modification numbers? Many thanks! Thanks for all the responses! This is ace :) Based on OneByOne's answer (which looked the simplest to me), I added some non-capturing groups (the '(?:' parts - thanks to VonC for introducing me to non-capturing groups!), so the groups that do capture only contain the digits or * character. ^(?:(\d+)\.)?(?:(\d+)\.)?(\*|\d+)$ Many thanks to everyone!

  • Is it valid to use unsafe struct * as an opaque type instead of IntPtr in .NET Platform Invoke?

    - by David Jeske
    .NET Platform Invoke advocates declaring pointer types as IntPtr. For example, the following [DllImport("user32.dll")] static extern IntPtr SendMessage(IntPtr hWnd, UInt32 Msg, Int32 wParam, Int32 lParam); However, I find when interfacing with interesting native interfaces, that have many pointer types, flattening everything into IntPtr makes the code very hard to read and removes the typical typechecking that a compiler can do. I've been using a pattern where I declare an unsafe struct to be an opaque pointer type. I can store this pointer type in a managed object, and the compiler can typecheck it form me. For example: class Foo { unsafe struct FOO {}; // opaque type unsafe FOO *my_foo; class if { [DllImport("mydll")] extern static unsafe FOO* get_foo(); [DllImport("mydll")] extern static unsafe void do_something_foo(FOO *foo); } public unsafe Foo() { this.my_foo = if.get_foo(); } public unsafe do_something_foo() { if.do_something_foo(this.my_foo); } While this example may not seem different than using IntPtr, when there are several pointer types moving between managed and native code, using these opaque pointer types for typechecking is a godsend. I have not run into any trouble using this technique in practice. However, I also have not seen an examples of anyone using this technique, and I wonder why. Is there any reason that the above code is invalid in the eyes of the .NET runtime? My main question is about how the .NET GC system treats "unsafe FOO *my_foo". Is this pointer something the GC system is going to try to trace, or is it simply going to ignore it? My hope is that because the underlying type is a struct, and it's declared unsafe, that the GC would ignore it. However, I don't know for sure. Thoughts?

  • What DVCS support Unicode filenames?

    - by Craig McQueen
    I'm interested in trying out distributed version control systems. git sounds promising, but I saw a note somewhere for the Windows port of git that says "don't use non-ASCII filenames". I can't find that now, but there is this link. It's put me off git for now, but I don't know if the other options are any better. Support for non-ASCII filenames is essential for my Japanese company. I'm looking for one that internally stores filenames as Unicode, not a platform-dependent encoding which would cause endless grief. So: What DVCS support Unicode filenames? In both Windows and Linux? Ideally, with the possibility to transfer repositories between Windows and Linux machines with minimal issues?

  • Threads in WCF service

    - by dragonfly
    Hi, there is a piece of code: class WCFConsoleHostApp : IBank { private static int _instanceCounter; public WCFConsoleHostApp () { Interlocked.Increment(ref _instanceCounter); Console.WriteLine(string.Format("{0:T} Instance nr " + _instanceCounter + " created", DateTime.Now)); } private static int amount; static void Main(string[] args) { ServiceHost host = new ServiceHost(typeof(WCFConsoleHostApp)); host.Open(); Console.WriteLine("Host is running..."); Console.ReadLine(); } #region IBank Members BankOperationResult IBank.Put(int amount) { Console.WriteLine(string.Format("{0:00} {1}", Thread.CurrentThread.ManagedThreadId, Thread.CurrentThread.IsThreadPoolThread) + " Putting..."); WCFConsoleHostApp.amount += amount; Thread.Sleep(20000); Console.WriteLine(string.Format("{0:00} {1}", Thread.CurrentThread.ManagedThreadId, Thread.CurrentThread.IsThreadPoolThread) + " Putting done"); return new BankOperationResult { CurrentAmount = WCFConsoleHostApp.amount, Success = true }; } BankOperationResult IBank.Withdraw(int amount) { Console.WriteLine(string.Format("{0:00} {1}", Thread.CurrentThread.ManagedThreadId, Thread.CurrentThread.IsThreadPoolThread) + " Withdrawing..."); WCFConsoleHostApp.amount -= amount; Thread.Sleep(20000); Console.WriteLine(string.Format("{0:00} {1}", Thread.CurrentThread.ManagedThreadId, Thread.CurrentThread.IsThreadPoolThread) + " Withdrawing done"); return new BankOperationResult { CurrentAmount = WCFConsoleHostApp.amount, Success = true }; } #endregion } My test client application calls that service in 50 threads (service is PerCall). What I found very disturbing is when I added Thread.Sleep(20000) WCF creates one service instance per second using different thread from pool. When I remove Thread.Sleep(20000) 50 instances are instanciated straight away, and about 2-4 threads are used to do it - which in fact I consider normal. Could somebody explain why when Thread.Sleep causes those funny delays in creating instances?

  • Programming challenge: can you code a hello world program as a Palindrome?

    - by Assaf Lavie
    So the puzzle is to write a hello world program in your language of choice, where the program's source file as a string has to be a palindrome. To be clear, the output has to be exactly "Hello, World". Edit: Well, with comments it seems trivial (not that I thought of it myself of course [sigh].. hat tip to cobbal). So new rule: no comments. Edit: I feel kind of bad editing someone else's question to say this, but it will eliminate a lot of non-palindromes that keep popping up, and I'm tired of seeing the same simple mistake over and over. The following is NOT a palindrome: ()() The following IS a palindrome: ())( Brackets, parenthesis, and anything else that must match are a major barrier to palindrome-ing, yes, but that doesn't mean you can ignore them and post non-palindrome answers. Languages represented thus far: C, C++, Bash, elisp, C#, Perl, sh, Windows shell, Java, Common Lisp, Awk, Ruby, Brainfuck, Funge, Python, Machine Language, HQ9+, Assembly, TCL, J, php, Haskell, io, TeX, APL, Javascript, mIRC Script, Basic, Orc, Fortran, Unlambda, Pseudo-code, Befunge, CFML, Lua, INTERCAL, VBScript, HTML, sed, PostScript, GolfScript, REBOL, SQL

  • Make winform run away from the mouse.

    - by JACK IN THE CRACK
    Okay so I'm trying to make a little gag program that will "run away" from the mouse. So, to get the mouse coordinates for the whole screen and not just the form control I had to create a little helper: static class MouseHelper { [DllImport("user32.dll")] [return: MarshalAs(UnmanagedType.Bool)] internal static extern bool GetCursorPos(ref Point pt); public static Point GetPosition() { Point w32Mouse = new Point(); GetCursorPos(ref w32Mouse); return w32Mouse; } } Now I thought I was going to use the MouseMove event... but that doesn't work for outside the form control either so I have an auto-enabled timer on a 10ms loop called timerMouseMove. public partial class Form1 : Form { public Form1() { InitializeComponent(); } private bool CollisionCheck() { Point win32Mouse = MouseHelper.GetPosition(); if (win32Mouse.X <= Location.X || win32Mouse.X >= (Location.X + Width)) return false; if (win32Mouse.Y <= Location.Y || win32Mouse.Y >= (Location.Y + Height)) return false; return true; } private void timerMouseMove_Tick(object sender, EventArgs e) { if (CollisionCheck()) Location = new Point(Location.X + 1, Location.Y + 1); } } So this works out nicely, at least I have the collision checking working and whatnot. But now, how should I go about figuring which side of the form the mouse has collided with, so that I can update its location to move in the opposite direction the mouse collides with it? And such halp

  • ListView adapter data change without ListView being notified

    - by brockoli
    I've written a ListActivity that has a custom list adapter. The list is being updated from a ContentProvider when onCreate is run. I also have a service that gets started when I run the app and it first updates the ContentProvider, then sends a Broadcast that the content has been updated. My ListActivity recieves the broadcast and tries to update my ListView. My problem is, I'm getting intermittent errors about the ListView adapter data changing without the ListView being notified. I call the notifyDataSetChanged() method on my list adapter right after I update it. What it seems like is happening is the list is still in the process of being updated after first call in onCreate when it recieves the broadcast from the service to update, so it tries to update my ListView before it's finished updating from it's first run. Does this make sense? Here is some of my code. NOTE: The service is working properly, it gets new data and updates my ContentProvider, and I do get the broadcast in my activity when it is updated. @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); ctx = this; getPrefs(); setContentView(R.layout.main); // Setup preference listener preferences = PreferenceManager.getDefaultSharedPreferences(this); preferences.registerOnSharedPreferenceChangeListener(listener); // Setup report list adapter ListView nzbLv = (ListView) findViewById(R.id.report_list); nzbla = new NZBReportListAdaptor(ctx); getReports(); nzbla.setListItems(report_list); nzbLv.setAdapter(nzbla); // Broadcast receiver to get notification from NZBService to update ReportList registerReceiver(receiver, new IntentFilter(NZBService.BROADCAST_ACTION)); startService(new Intent(ctx, NZBService.class)); } @Override public void onResume() { super.onResume(); timerHandler.resume(); new updateSabQueue().execute(); //updateList(); } @Override public void onPause() { super.onPause(); timerHandler.pause(); unregisterReceiver(receiver); } private BroadcastReceiver receiver = new BroadcastReceiver() { public void onReceive(Context context, Intent intent) { Toast.makeText(ctx, "NZBService broadcast recieved", Toast.LENGTH_SHORT).show(); updateReportList(); } }; private void updateReportList() { new updateReportList().execute(); } private class updateReportList extends AsyncTask<Void, Void, Boolean> { /* (non-Javadoc) * @see android.os.AsyncTask#onPreExecute() * Show progress dialog */ protected void onPreExecute() { } /* (non-Javadoc) * @see android.os.AsyncTask#doInBackground(Params[]) * Get new articles from the internet */ protected Boolean doInBackground(Void...unused) { getReports(); return true; } /** * On post execute. * Close the progress dialog */ @Override protected void onPostExecute(Boolean updated) { if (updated) { Log.d(TAG, "NZB report list adapter updated"); synchronized(this) { nzbla.setListItems(report_list); } Log.d(TAG, "NZB report list notified of change"); nzbla.notifyDataSetChanged(); } } } Now that this question is answered, I will post my updated code in an effort to help others who might come across it. @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); ctx = this; getPrefs(); setContentView(R.layout.main); // Setup preference listener preferences = PreferenceManager.getDefaultSharedPreferences(this); preferences.registerOnSharedPreferenceChangeListener(listener); // Setup report list adapter ListView nzbLv = (ListView) findViewById(R.id.report_list); nzbla = new NZBReportListAdaptor(ctx); report_list.addAll(getReports()); nzbla.setListItems(report_list); nzbLv.setAdapter(nzbla); // Broadcast receiver to get notification from NZBService to update ReportList registerReceiver(receiver, new IntentFilter(NZBService.BROADCAST_ACTION)); startService(new Intent(ctx, NZBService.class)); } private class updateReportList extends AsyncTask<Void, Void, ArrayList<Report>> { /* (non-Javadoc) * @see android.os.AsyncTask#onPreExecute() * Show progress dialog */ protected void onPreExecute() { } /* (non-Javadoc) * @see android.os.AsyncTask#doInBackground(Params[]) * Get new articles from the internet */ protected ArrayList<Report> doInBackground(Void...unused) { return getReports(); } /** * On post execute. * Close the progress dialog */ @Override protected void onPostExecute(ArrayList<Report> updated) { nzbla.setListItems(updated); nzbla.notifyDataSetChanged(); } } private ArrayList<Report> getReports() { ArrayList<Report> reports = new ArrayList<Report>(); ContentResolver r = getContentResolver(); Cursor c = r.query(NZBReportProvider.CONTENT_URI, null, null, null, NZBReportProvider.ARTICLE_KEY_ROWID + " DESC"); startManagingCursor(c); Log.d(TAG, "NZBReport cursor.getCount=" + c.getCount()); int title = c.getColumnIndex(NZBReportProvider.ARTICLE_KEY_TITLE); int desc = c.getColumnIndex(NZBReportProvider.ARTICLE_KEY_DESCRIPTION); int cat = c.getColumnIndex(NZBReportProvider.ARTICLE_KEY_CAT); int size = c.getColumnIndex(NZBReportProvider.ARTICLE_KEY_SIZE); int link = c.getColumnIndex(NZBReportProvider.ARTICLE_KEY_LINK); int catid = c.getColumnIndex(NZBReportProvider.ARTICLE_KEY_CATID); int date = c.getColumnIndex(NZBReportProvider.ARTICLE_KEY_DATE_ADDED); int group = c.getColumnIndex(NZBReportProvider.ARTICLE_KEY_GROUP); if (c.getCount() > 0) { c.moveToFirst(); do { URL url = null; try { url = new URL(c.getString(link)); } catch (MalformedURLException e) { // TODO Auto-generated catch block e.printStackTrace(); } reports.add(new Report(c.getString(title), url, c.getString(desc), c.getString(cat), c.getString(date), c.getString(size), c.getInt(catid), c.getString(group))); } while (c.moveToNext()); } return reports; }

  • Compiling and linking libcurl to create a stand alone dll

    - by Haraldo
    Hi, I've managed to compile a dll with the necessary linked libraries (*.lib) and with CURL_STATICLIB set in the preprocessor section among other settings. I'm using "libcurl-7.19.3-win32-ssl-msvc.zip" package and compiling with VS 2008 express. This has been the first version I managed to get compiled properly with no link issues etc. The problem I have now is that my dll needs libcurl.dll to function and this is not ok. My dll needs to be independent. I have no idea how to implement this. I've taken all day just to get what I've got compiled. I've got runtime library set to Multi threaded dll (debug/release) respectively under C/C++ - code generation. I've a number of preprocessor set - CURL_STATICLIB being one of them. Configuration Type is set to Dynamic Library Use of MFC is set to Use MFC in a static library Additional Library Directories is set to the lib folders (debug/release) respectively. I've noticed there is a curllib_static.lib file which I've tried instead of curllib.lib as an additional dependency but it only compiles with the later. This is driving me nuts! So I guess I need some guidance as to how to make my dll completely static so it doesn't have any dependencies. I notice my dll is currently dependent on: CURLLIB.DLL MSVCR90D.DLL As I'm pretty new to C++ it could be a setting I'm missing in VS 2008 but I'm not sure. One person said I should be using a static library with *.a files (libcurl.a) etc but when I do this I get link errors which I haven't been able to resolve. Any guidance here would be much appreciated.

  • How to define index by several columns in hibernate entity?

    - by foobar
    Morning. I need to add indexing in hibernate entity. As I know it is possible to do using @Index annotation to specify index for separate column but I need an index for several fields of entity. I've googled and found jboss annotation @Table, that allows to do this (by specification). But (I don't know why) this functionality doesn't work. May be jboss version is lower than necessary, or maybe I don't understant how to use this annotation, but... complex index is not created. Why index may not be created? jboss version 4.2.3.GA Entity example: package somepackage; import org.hibernate.annotations.Index; import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.Id; @Entity @org.hibernate.annotations.Table(appliesTo = House.TABLE_NAME, indexes = { @Index(name = "IDX_XDN_DFN", columnNames = {House.XDN, House.DFN} ) } ) public class House { public final static String TABLE_NAME = "house"; public final static String XDN = "xdn"; public final static String DFN = "dfn"; @Id @GeneratedValue private long Id; @Column(name = XDN) private long xdn; @Column(name = DFN) private long dfn; @Column private String address; public long getId() { return Id; } public void setId(long id) { this.Id = id; } public long getXdn() { return xdn; } public void setXdn(long xdn) { this.xdn = xdn; } public long getDfn() { return dfn; } public void setDfn(long dfn) { this.dfn = dfn; } public String getAddress() { return address; } public void setAddress(String address) { this.address = address; } } When jboss/hibernate tries to create table "house" it throws following exception: Reason: org.hibernate.AnnotationException: @org.hibernate.annotations.Table references an unknown table: house

  • Fun things you can do by mutating Java strings

    So I've come around since I asked how to limit setAccessible to only “legitimate” uses and have come to embrace its power for fun. Enabled by its power, of course, is string mutation. import java.lang.reflect.Field; public class Mutator { static void mutate(Object obj, String field, Object newValue) { try { Field f = obj.getClass().getDeclaredField(field); f.setAccessible(true); f.set(obj, newValue); } catch (Exception e) { } } public static void mutate(String from, String to) { mutate(from, "value", to.toCharArray()); mutate(from, "count", to.length()); } public static void main(String args[]) { Mutator.mutate(System.getProperty("line.separator"), "<br/>\n"); System.out.println("Hello world!"); Mutator.mutate(Integer.toString(Integer.MIN_VALUE), "OMG!"); System.out.println(-2147483648); Mutator.mutate(String.valueOf((Object) null), "LOL!"); System.out.println(Arrays.toString(new int[3][])); Mutator.mutate(Arrays.toString(new int[0]), ":("); System.out.println(Arrays.toString(new byte[0])); } } Output (if no exception is thrown): Hello world!<br/> OMG!<br/> [LOL!, LOL!, LOL!]<br/> :(<br/> Let's see what other fun things we can come up with.

  • Spring Stripes framework problem

    - by ali
    I am new to stripes and am attempting to integrate spring into stripes In the following code : public class ContactFormActionBeanTest { private static MockServletContext mockServletContext; private static MockHttpSession mockSession; @BeforeClass public static void setup() throws Exception { mockServletContext = new MockServletContext("webmail"); Map<String,String> params = new HashMap<String,String>(); params.put("ActionResolver.Packages", "stripesbook.action"); params.put("Extension.Packages", "stripesbook.ext," + "net.sourceforge.stripes.integration.spring"); mockServletContext.addFilter(StripesFilter.class, "StripesFilter", params); mockServletContext.setServlet(DispatcherServlet.class, "DispatcherServlet", null); mockSession = new MockHttpSession(mockServletContext); mockServletContext.addInitParameter("contextConfigLocation", "/WEB-INF/applicationContext-test.xml"); ContextLoaderListener springContextLoader = new ContextLoaderListener(); springContextLoader.contextInitialized( new ServletContextEvent(mockServletContext)); // Load mock user MockRoundtrip trip = new MockRoundtrip(mockServletContext, MockDataLoaderActionBean.class, mockSession); trip.execute(); // Login mock user trip = new MockRoundtrip(mockServletContext, LoginActionBean.class, mockSession); trip.setParameter("username", "freddy"); trip.setParameter("password", "nadia"); trip.execute("login"); } I get null in springContextLoader ContextLoaderListener springContextLoader = new ContextLoaderListener(); and test fails. Am I missing something? I am using eclipse with maven. Also when I try to deploy it for tomcat 6.0 I get following warnings: WARN net.sourceforge.stripes.util.ResolverUtil - Could not examine class 'stripesbook/ext/ContactFormatter.class' due to a java.lang.UnsupportedClassVersionError with message: Bad version number in .class file (unable to load class stripesbook.ext.ContactFormatter) I have checked to be sure that I am compiling with Java 5(set JDK compiler to 1.5) instead of 1.6 (Java 6); but didn't work out for me and still have problems running spring-stripes integrated project.

  • Array Recursion

    - by GeeYouAreYou
    I've got an assignment I can't figure out, any pointers will be much appreciated, it goes like so: There's a series of light bulbs represented as an array of true/false, there's a switch for every light bulb, by clicking it for any light bulb, you toggle it as well as 2 adjacent ones (1 from left & another 1 from right; if clicked switch's bulb on edge -- only 1 adjacent toggled of course). What is needed to accomplish is a method that accepts an array of a series of turned on/off light bulbs and another one representing another state of supposedly the 1st array after some switches have been clicked..! So recursion must be used to find out whether there's a combination of switch clicks that will transform array 1 to array 2. Here's the signature of the method: public static boolean disco(boolean[] init, boolean[] target) Will return true if array init can be transformed to target, false otherwise. Method must be static and not use any other static and global variables, only local. Example: boolean[] init = {true, false, true, false, true, false}; boolean[] target = {false, true, false, true, false, true}; For above 2 arrays, disco(init, target) will return true because toggling the 1st and 4th bulbs would yield the target state (remember adjacent bulbs being toggled as well). Any help much appreciated..!!

  • How to refactor these generic methods?

    - by Steve Crane
    I have written two nearly identical generic extension methods and am trying to figure out how I might refactor them into a single method. They differ only in that one operates on List and the other on List, and the properties I'm interested in are AssetID for AssetDocument and PersonID for PersonDocument. Although AssetDocument and PersonDocument have the same base class the properties are defined in each class so I don't think that helps. I have tried public static string ToCSVList<T>(this T list) where T : List<PersonDocument>, List<AssetDocument> thinking I might then be able to test the type and act accordingly but this results in the syntax error Type parameter 'T' inherits conflicting constraints These are the methods that I would like to refactor into a single method but perhaps I am simply going overboard and they would besat be left as they are. I'd like to hear what you think. public static string ToCSVList<T>(this T list) where T : List<AssetDocument> { var sb = new StringBuilder(list.Count * 36 + list.Count); string delimiter = String.Empty; foreach (var document in list) { sb.Append(delimiter + document.AssetID.ToString()); delimiter = ","; } return sb.ToString(); } public static string ToCSVList<T>(this T list) where T : List<PersonDocument> { var sb = new StringBuilder(list.Count * 36 + list.Count); string delimiter = String.Empty; foreach (var document in list) { sb.Append(delimiter + document.PersonID.ToString()); delimiter = ","; } return sb.ToString(); }

  • How to make a product catalog in C#?

    - by Ervin
    I need to develop a product catalog (about 4000 products) application, which would be given to clients on CD or DVD. The catalog exists in webpage format using PHP and MySQL. IMPORTANT: the application is given to clients who maight have old PC, old System. For minimal requirements I would put Windows XP and Internet Explorer 6 (if needed). I need the following features: 1 search option (after productID AND after keyword) 2 print option (by selecting multiple products) 3 shopping cart (making a list which will be sent to an email address if there is any Internet Connection on the computer) When I was asked to do it I had 2 days to realise a very basic version, so I took the whole website and exported it in HTML pages, and developed an application in C# which contains an embeded browser. So the whole website is now static and put on a CD. Everything fine so far. Now here are the problems: 1. the search option was realized by parsing the html files and reading the productID or looking for keywords inside of them. Put on a CD it was extremely slow (searching in 600MB of html files). FOR THIS I WOULD NEED A SOLUTION WITH A STATIC DATABASE (USING ACCESS OR SOMETHING) TO HAVE INDEXED ROWS, SO THE SEARCH COULD BE A VERY FAST ONE. 2. the printing option was a simply call of the embeded Internet Explorer print functions. Here are two problems: a) user needs IE7 for printing the website scaled (FIT TO PAGE), otherwise the edges of the page are cut down. b) users of this app does not have even the basic PC usage skills, so they can't set the printing settings, so there will appear in header and footer the page numbers and titles. QUESTION: can I set these settings from CSS for printing? 3. couldn't make a a shopping cart as I don't use a database, so I have static websites and content is inside the HTML. QUESTION: WHICH ARE THE BEST SOLUTIONS FOR THE PROBLEMS DESCRIBED ABOVE? PLEASE ANSWER EVEN IF YOUR ANSWER IS FOR ONE QUESTION ONLY. THANKS

  • How to reliably replace a library-defined error handler with my own?

    - by sharptooth
    On certain error cases ATL invokes AtlThrow() which is implemented as ATL::AtlThrowImpl() which in turn throws CAtlException. The latter is not very good - CAtlException is not even derived from std::exception and also we use our own exceptions hierarchy and now we will have to catch CAtlException separately here and there which is lots of extra code and error-prone. Looks like it is possible to replace ATL::AtlThrowImpl() with my own handler - define _ATL_CUSTOM_THROW and define AtlThrow() to be the custom handler before including atlbase.h - and ATL will call the custom handler. Not so easy. Some of ATL code is not in sources - it comes compiled as a library - either static or dynamic. We use the static - atls.lib. And... it is compiled in such way that it has ATL::ThrowImpl() inside and some code calling it. I used a static analysis tool - it clearly shows that there're paths on which the old default handler is called. To ensure I even tried to "reimplement" ATL::AtlThrowImpl() in my code. Now the linker says it sees two declarations of ATL::AtlThrowImpl() which I suppose confirms that there's another implementation that can be called by some code. How can I handle this? How do I replace the default handler completely and ensure that the default handler is never called?
