• MVC repository pattern design decision

  - by bradjive

  I have an asp .net MVC application and recently started implementing the repository pattern with a service validation layer, much like this. I've been creating one repository/service for each model that I create. Is this overkill? Instead, should I create one repository/service for each logical business area that provides CRUD for many different models? To me, it seems like I'm either cluttering the project tree with many files or cluttering a class with many methods. 6 one way half dozen the other. Can you think of any good arguments either way?

• C# How to get the current project directory or the bin directory and move a few level up?

  - by melaos

  Hi there, I have an ASP.Net MVC app, and i have some xsl files inside of the Content directory. I've try a few methods to get directory dynamically buy keep on coming short. So how do i get the directory to point to the Content/xsl folder? the closest that i came to was with this: this.GetType().Assembly.CodeBase which only returns the project DLL, but i can't figure out how to move up a few levels from there or what .net library to use to navigate around the path. there's no ../.. :( Basically i want to navigate to the Content/xsl folder which is at the same level of the Bin directory. Any idea? thanks.

• Safari Extjs grid rendering issue

  - by Natkeeran

  Hello: Here is a simple illustration of what I mean. It works in IE, and FF, but not in Safari. I have four panels which are dynamically added to a tabpanel item. Three are grid panels, and one is a form panel. I need to preserve the grids proportions or sizes. I tried several layout methods (table, column, absolute etc), and nothing seems work so far. For table layout, all sizes end up being the same width. It seems my best bet is column layout, and they seem to render properly in FF, IE, but not in Safari as shown in the image. (Here it seems that column goes to second row, when the item does not fit into the current row). Initially, the title bar, and several of the column headings does not show. Any suggestions. Thank you.

• Blackberry - Custom EditField Cursor

  - by varun

  Hi, I am new to Blackberry Development.This is my first Question for you people. I am creating a search box for my project. But it looks like blackberry doesn't have an internal api for creating single line Edit field. I have created a Custom Field by extending BasciEditField overriding methods like layout, paint. In paint i am drawing a rectangle with getpreferred width and height. But the cursor is coming at default position (top-left) in Edit Field. Can any body tell me how i can draw it where my text is(i.e in middle of Edit Field by calling drwaText()). Thanks,

• Debugging unmanaged code while debugging managed code

  - by sc_ray

  Hi, The .NET 3.5 application I am working on consists of bunch of different solutions. Some of these solutions consist of managed code(C#) and others have unmanaged code(C++). Methods written in C# communicate with the ones written in C++. I am trying to trace the dependencies between these various functions and I thought setting breakpoints on the solution consisting my C++ functions. One of the C# solutions have the startup project. I run this solution in debug mode with the expectation that the breakpoints in my unmanaged code will be hit but nothing really happens. Can somebody guide me through the process of debugging mixed applications such as these using the Visual Studio IDE? Thanks

• Android: TabHost How To: set new content in existing tabs upon menu button?

  - by Martin D.

  Hello stackoverflow, I recently started Android programming and was working on my first program which displays a historic text document, sectioned by tabs via TabHost. I have limited my program to one activity and merely used setContent in my TabSpec's to switch between different XML views. The document has both unedited and corrected versions of the text for which I have built text views to accommodate. I wanted to implement the standard menu to have buttons to "view corrected" and "view original" and switch the content of the tabs which have changes (without altering the tabs or their indicators). I've read on the TabHost API and there is no way to edit existing tab content with setContent() of TabSpec; and AFAIK TabWidget only affects the actual tabs, not the content that is displayed upon pressing them. I've thought about creating a new class which extended TabHost and super() all of the original methods, while including one more which updated the mTabSpec list. My question would be, how would I update the frameLayout view of a specific tab to display content I specify?

• How to configure LocalSessionFactoryBean to release connections after transaction end?

  - by peter

  I am testing an application (Spring 2.5, Hibernate 3.5.0 Beta, Atomikos 3.6.2, and Postgreql 8.4.2) with the configuration for the DAO listed below. The problem that I see is that the pool of 10 connections with the dataSource gets exhausted after the 10's transaction. I know 'hibernate.connection.release_mode' has no effect unless the session is obtained with openSession rather then using a contextual session. I am wandering if anyone has found a way to configure the LocalSessionFactoryBean to release connections after any transaction.

• Tableview reload data problem iphone sdk

  - by neha

  Hi all, I have a class A which is a subclass of uitableviewcontroller and one more class B which actually displays my tableview with its content is a subclass of A. There's an xml parser which parses my xml and stores the content in an nsmutablearray of application delegate. Now, I fetch this delegate array into a local nsmutablearray in class B to minimise the communication between the two classes i.e. delegate and class B and display that. After certain condition is met in class A, I'm calling xml parser to refill the delegate array and I'm calling class B's tableview reload method. The problem is when I call the tableview's reload data, class B's delegate methods are called. But before that I need to grab this delegate array in local array in class B. How shall I do that? Can anybody please help? Thanx in advance.

• Cannot SSH after resetting firewall on VPS

  - by Thomas Buckley

  I'm having trouble trying to SSH to my Debian 5 VPS with blacknight. It was working fine until I did the following: Logged into 'Parallels Infrastructure Manager' - Container - Firewall - Set to 'Normal Firewall settings'. It told me there was an error with the IPTables and offered the option again with a checkbox to 'reset' firewall settings, I selected this. I can see that that the default rules are been applied ( anything from anyone on any port and allowing anything to happen).

• Ho can I tell when the background is touched on a UICollectionView?

  - by Mason Cloud

  I've tried subclassing UICollectionView and overriding touchesBegan:withEvent: and hitTest:WithEvent:, and both of those methods trigger when I touch a cell. However, if I touch the space between the cells, nothing happens at all. Here's what I've created: @interface WSImageGalleryCollectionView : UICollectionView @end ..and.. @implementation WSImageGalleryCollectionView - (void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { NSLog(@"Touches began"); [super touchesBegan:touches withEvent:event]; } - (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event { NSLog(@"Hit test reached"); return [super hitTest:point withEvent:event]; } @end

• How can I assert from Python C code?

  - by Joe

  I'm writing a Python class in C and I want to put assertions in my debug code. assert.h suits me fine. This only gets put in debug compiles so there's no chance of an assert failure impacting a user of the Python code*. I'm trying to divide my 'library' code (which should be separate to the code linked against Python) so I can use it from other C code. My Python methods are therefore thinnish wrappers around my pure-C code. So I can't do this in my 'library' code: if (black == white) { PyErr_SetString(PyExc_RuntimeError, "Remap failed"); } because this pollutes my pure-C code with Python. It's also far uglier than a simple assert(black != white); I believe that the Distutils compiler always sets NDEBUG, which means I can't use assert.h even in debug builds. Mac OS and Linux. Help! *one argument I've heard against asserting in C code called from Python.

• A plugin is preventing Eclipse from starting up

• Getting started with Exchange Web Services 2010

  - by Adam Tuttle

  I've been tasked with writing a SOAP web-service in .Net to be middleware between EWS2010 and an application server that previously used WebDAV to connect to Exchange. (As I understand it, WebDAV is going away with EWS2010, so the application server will no longer be able to connect as it previously did, and it is exponentially harder to connect to EWS without WebDAV. The theory is that doing it in .Net should be easier than anything else... Right?!) My end goal is to be able to get and create/update email, calendar items, contacts, and to-do list items for a specified Exchange account. (Deleting is not currently necessary, but I may build it in for future consideration, if it's easy enough). I was originally given some sample code, which did in fact work, but I quickly realized that it was outdated. The types and classes used appear nowhere in the current documentation. For example, the method used to create a connection to the Exchange server was: ExchangeService svc = new ExchangeService(); svc.Credentials = new WebCredentials(AuthEmailAddress, AuthEmailPassword); svc.AutodiscoverUrl(AutoDiscoverEmailAddress); For what it's worth, this was using an assembly that came with the sample code: Microsoft.Exchange.WebServices.dll ("MEWS"). Before I realized that this wasn't the current standard way to accomplish the connection, and it worked, I tried to build on it and add a method to create calendar items, which I copied from here: static void CreateAppointment(ExchangeServiceBinding esb) { // Create the appointment. CalendarItemType appointment = new CalendarItemType(); ... } Right away, I'm confronted with the difference between ExchangeService and ExchangeServiceBinding ("ESB"); so I started Googling to try and figure out how to get an ESB definition so that the CreateAppointment method will compile. I found this blog post that explains how to generate a proxy class from a WSDL, which I did. Unfortunately, this caused some conflicts where types that were defined in the original Assembly, Microsoft.Exchange.WebServices.dll (that came with the sample code) overlapped with Types in my new EWS.dll assembly (which I compiled from the code generated from the services.wsdl provided by the Exchange server). I excluded the MEWS assembly, which only made things worse. I went from a handful of errors and warnings to 25 errors and 2,510 warnings. All kinds of types and methods were not found. Something is clearly wrong, here. So I went back on the hunt. I found instructions on adding service references and web references (i.e. the extra steps it takes in VS2008), and I think I'm back on the right track. I removed (actually, for now, just excluded) all previous assemblies I had been trying; and I added a service reference for https://my.exchange-server.com/ews/services.wsdl Now I'm down to just 1 error and 1 warning. Warning: The element 'transport' cannot contain child element 'extendedProtectionPolicy' because the parent element's content model is empty. This is in reference to a change that was made to web.config when I added the service reference; and I just found a fix for that here on SO. I've commented that section out as indicated, and it did make the warning go away, so woot for that. The error hasn't been so easy to get around, though: Error: The type or namespace name 'ExchangeService' could not be found (are you missing a using directive or an assembly reference?) This is in reference to the function I was using to create the EWS connection, called by each of the web methods: private ExchangeService getService(String AutoDiscoverEmailAddress, String AuthEmailAddress, String AuthEmailPassword) { ExchangeService svc = new ExchangeService(); svc.Credentials = new WebCredentials(AuthEmailAddress, AuthEmailPassword); svc.AutodiscoverUrl(AutoDiscoverEmailAddress); return svc; } This function worked perfectly with the MEWS assembly from the sample code, but the ExchangeService type is no longer available. (Nor is ExchangeServiceBinding, that was the first thing I checked.) At this point, since I'm not following any directions from the documentation (I couldn't find anywhere in the documentation that said to add a service reference to your Exchange server's services.wsdl -- but that does seem to be the best/farthest I've gotten so far), I feel like I'm flying blind. I know I need to figure out whatever it is that should replace ExchangeService / ExchangeServiceBinding, implement that, and then work through whatever errors crop up as a result of that switch... But I have no idea how to do that, or where to look for how to do it. Googling "ExchangeService" and "ExchangeServiceBinding" only seem to lead back to outdated blog posts and MSDN, neither of which has proven terribly helpful thus far. Help me, Obi-Wan, you're my only hope!

• JPA : optimize EJB-QL query involving large many-to-many join table

  - by Fabien

  Hi all. I'm using Hibernate Entity Manager 3.4.0.GA with Spring 2.5.6 and MySql 5.1. I have a use case where an entity called Artifact has a reflexive many-to-many relation with itself, and the join table is quite large (1 million lines). As a result, the HQL query performed by one of the methods in my DAO takes a long time. Any advice on how to optimize this and still use HQL ? Or do I have no choice but to switch to a native SQL query that would perform a join between the table ARTIFACT and the join table ARTIFACT_DEPENDENCIES ? Here is the problematic query performed in the DAO : @SuppressWarnings("unchecked") public List<Artifact> findDependentArtifacts(Artifact artifact) { Query query = em.createQuery("select a from Artifact a where :artifact in elements(a.dependencies)"); query.setParameter("artifact", artifact); List<Artifact> list = query.getResultList(); return list; } And the code for the Artifact entity : package com.acme.dependencytool.persistence.model; import java.util.ArrayList; import java.util.List; import javax.persistence.CascadeType; import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.FetchType; import javax.persistence.GeneratedValue; import javax.persistence.Id; import javax.persistence.JoinColumn; import javax.persistence.JoinTable; import javax.persistence.ManyToMany; import javax.persistence.Table; import javax.persistence.UniqueConstraint; @Entity @Table(name = "ARTIFACT", uniqueConstraints={@UniqueConstraint(columnNames={"GROUP_ID", "ARTIFACT_ID", "VERSION"})}) public class Artifact { @Id @GeneratedValue @Column(name = "ID") private Long id = null; @Column(name = "GROUP_ID", length = 255, nullable = false) private String groupId; @Column(name = "ARTIFACT_ID", length = 255, nullable = false) private String artifactId; @Column(name = "VERSION", length = 255, nullable = false) private String version; @ManyToMany(cascade=CascadeType.ALL, fetch=FetchType.EAGER) @JoinTable( name="ARTIFACT_DEPENDENCIES", joinColumns = @JoinColumn(name="ARTIFACT_ID", referencedColumnName="ID"), inverseJoinColumns = @JoinColumn(name="DEPENDENCY_ID", referencedColumnName="ID") ) private List<Artifact> dependencies = new ArrayList<Artifact>(); public Long getId() { return id; } public void setId(Long id) { this.id = id; } public String getGroupId() { return groupId; } public void setGroupId(String groupId) { this.groupId = groupId; } public String getArtifactId() { return artifactId; } public void setArtifactId(String artifactId) { this.artifactId = artifactId; } public String getVersion() { return version; } public void setVersion(String version) { this.version = version; } public List<Artifact> getDependencies() { return dependencies; } public void setDependencies(List<Artifact> dependencies) { this.dependencies = dependencies; } } Thanks in advance. EDIT 1 : The DDLs are generated automatically by Hibernate EntityMananger based on the JPA annotations in the Artifact entity. I have no explicit control on the automaticaly-generated join table, and the JPA annotations don't let me explicitly set an index on a column of a table that does not correspond to an actual Entity (in the JPA sense). So I guess the indexing of table ARTIFACT_DEPENDENCIES is left to the DB, MySQL in my case, which apparently uses a composite index based on both clumns but doesn't index the column that is most relevant in my query (DEPENDENCY_ID). mysql describe ARTIFACT_DEPENDENCIES; +---------------+------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +---------------+------------+------+-----+---------+-------+ | ARTIFACT_ID | bigint(20) | NO | MUL | NULL | | | DEPENDENCY_ID | bigint(20) | NO | MUL | NULL | | +---------------+------------+------+-----+---------+-------+ EDIT 2 : When turning on showSql in the Hibernate session, I see many occurences of the same type of SQL query, as below : select dependenci0_.ARTIFACT_ID as ARTIFACT1_1_, dependenci0_.DEPENDENCY_ID as DEPENDENCY2_1_, artifact1_.ID as ID1_0_, artifact1_.ARTIFACT_ID as ARTIFACT2_1_0_, artifact1_.GROUP_ID as GROUP3_1_0_, artifact1_.VERSION as VERSION1_0_ from ARTIFACT_DEPENDENCIES dependenci0_ left outer join ARTIFACT artifact1_ on dependenci0_.DEPENDENCY_ID=artifact1_.ID where dependenci0_.ARTIFACT_ID=? Here's what EXPLAIN in MySql says about this type of query : mysql explain select dependenci0_.ARTIFACT_ID as ARTIFACT1_1_, dependenci0_.DEPENDENCY_ID as DEPENDENCY2_1_, artifact1_.ID as ID1_0_, artifact1_.ARTIFACT_ID as ARTIFACT2_1_0_, artifact1_.GROUP_ID as GROUP3_1_0_, artifact1_.VERSION as VERSION1_0_ from ARTIFACT_DEPENDENCIES dependenci0_ left outer join ARTIFACT artifact1_ on dependenci0_.DEPENDENCY_ID=artifact1_.ID where dependenci0_.ARTIFACT_ID=1; +----+-------------+--------------+--------+-------------------+-------------------+---------+---------------------------------------------+------+-------+ | id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra | +----+-------------+--------------+--------+-------------------+-------------------+---------+---------------------------------------------+------+-------+ | 1 | SIMPLE | dependenci0_ | ref | FKEA2DE763364D466 | FKEA2DE763364D466 | 8 | const | 159 | | | 1 | SIMPLE | artifact1_ | eq_ref | PRIMARY | PRIMARY | 8 | dependencytooldb.dependenci0_.DEPENDENCY_ID | 1 | | +----+-------------+--------------+--------+-------------------+-------------------+---------+---------------------------------------------+------+-------+ EDIT 3 : I tried setting the FetchType to LAZY in the JoinTable annotation, but I then get the following exception : Hibernate: select artifact0_.ID as ID1_, artifact0_.ARTIFACT_ID as ARTIFACT2_1_, artifact0_.GROUP_ID as GROUP3_1_, artifact0_.VERSION as VERSION1_ from ARTIFACT artifact0_ where artifact0_.GROUP_ID=? and artifact0_.ARTIFACT_ID=? 51545 [btpool0-2] ERROR org.hibernate.LazyInitializationException - failed to lazily initialize a collection of role: com.acme.dependencytool.persistence.model.Artifact.dependencies, no session or session was closed org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: com.acme.dependencytool.persistence.model.Artifact.dependencies, no session or session was closed at org.hibernate.collection.AbstractPersistentCollection.throwLazyInitializationException(AbstractPersistentCollection.java:380) at org.hibernate.collection.AbstractPersistentCollection.throwLazyInitializationExceptionIfNotConnected(AbstractPersistentCollection.java:372) at org.hibernate.collection.AbstractPersistentCollection.readSize(AbstractPersistentCollection.java:119) at org.hibernate.collection.PersistentBag.size(PersistentBag.java:248) at com.acme.dependencytool.server.DependencyToolServiceImpl.createArtifactViewBean(DependencyToolServiceImpl.java:93) at com.acme.dependencytool.server.DependencyToolServiceImpl.createArtifactViewBean(DependencyToolServiceImpl.java:109) at com.acme.dependencytool.server.DependencyToolServiceImpl.search(DependencyToolServiceImpl.java:48) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at com.google.gwt.user.server.rpc.RPC.invokeAndEncodeResponse(RPC.java:527) at com.google.gwt.user.server.rpc.RemoteServiceServlet.processCall(RemoteServiceServlet.java:166) at com.google.gwt.user.server.rpc.RemoteServiceServlet.doPost(RemoteServiceServlet.java:86) at javax.servlet.http.HttpServlet.service(HttpServlet.java:637) at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) at org.mortbay.jetty.servlet.ServletHolder.handle(ServletHolder.java:487) at org.mortbay.jetty.servlet.ServletHandler.handle(ServletHandler.java:362) at org.mortbay.jetty.security.SecurityHandler.handle(SecurityHandler.java:216) at org.mortbay.jetty.servlet.SessionHandler.handle(SessionHandler.java:181) at org.mortbay.jetty.handler.ContextHandler.handle(ContextHandler.java:729) at org.mortbay.jetty.webapp.WebAppContext.handle(WebAppContext.java:405) at org.mortbay.jetty.handler.HandlerWrapper.handle(HandlerWrapper.java:152) at org.mortbay.jetty.handler.RequestLogHandler.handle(RequestLogHandler.java:49) at org.mortbay.jetty.handler.HandlerWrapper.handle(HandlerWrapper.java:152) at org.mortbay.jetty.Server.handle(Server.java:324) at org.mortbay.jetty.HttpConnection.handleRequest(HttpConnection.java:505) at org.mortbay.jetty.HttpConnection$RequestHandler.content(HttpConnection.java:843) at org.mortbay.jetty.HttpParser.parseNext(HttpParser.java:647) at org.mortbay.jetty.HttpParser.parseAvailable(HttpParser.java:205) at org.mortbay.jetty.HttpConnection.handle(HttpConnection.java:380) at org.mortbay.io.nio.SelectChannelEndPoint.run(SelectChannelEndPoint.java:395) at org.mortbay.thread.QueuedThreadPool$PoolThread.run(QueuedThreadPool.java:488)

• Android TabHost: update tabs from tab's activity

  - by joshuadlillie

  I have a TabActivity and am going to have 3 or 4 tabs. In TabA, I would like to have an ExpandableListView, which will list products. I would like TabC to act as a sort of "shopping cart", probably with a ListView of itself. So, my question is: is there a way to interact with the TabHost from the Activity? I would like to be able to click a button inside of TabA and have it update and switch to TabC. Is this possible? Can I get the Tab's activities call it's parents methods?

• Android: Programmatically move between images in Gallery widget

  - by bdls

  I'd like to programmatically move between images in the Gallery widget, with animation. I can change the currently displaying image using the setSelection(int position) method, however that does not animate. Then there's setSelection(int position, bool animate) but the extra boolean on the end there doesn't appear to do anything. In the source of Gallery it appears that it can handle DPAD key-presses, so a work-around I thought of was to fake the key-presses. Eg. dispatchKeyEvent(new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_DPAD_LEFT)) However I can't get this working for some reason. Anyone tried this? I notice three of the widget's methods I'd love to use moveNext(), movePrevious() and scrollToChild() are all private and unusable. Does anyone know how I might be able to do this?

• FB.ui and setting popup size

  - by manuelpedrera

  I am using FB.ui with the display parameter set to popup. When the method is 'stream.publish', it autoresizes when the content is loaded. However, when using 'fbml.dialog' (in order to display a multi-friend selector) it shows a size that I'm not able to change (and the content is displayed cropped). I have tried with the following approaches, with no luck: FB.ui({ method: 'fbml.dialog', size: {width: 800, height: 500}, ... FB.ui({ method: 'fbml.dialog', width: 800, height: 500, ... Also I've been looking at the API source code, and it declares the method this way: Method declaration: 'fbml.dialog': { size : { width: 575, height: 300 }, url : 'render_fbml.php', loggedOutIframe : true }... Functions that executes the methods: // the basic call data var call = { cb : cb, id : id, size : method.size || {}, url : FB._domain.www + method.url, params : params }; Any help would be much appreciated...

• Fiscal year handling strategies in database design

  - by Sapphire

  By fiscal year I mean all the data in the database (in all tables) that occurred in the particular year. Lets say that we are building an application that allows user to choose from different years. What way of implementing this would you prefer, and why: Separate fiscal year data based on multiple separate database instances (for example, on every fiscal year start you could create a new instance with no data) Have everything in one database, but with logic that automatically separates records from different years. Personally, I have "seen" both methods, and I would choose the second. The only argument I can think of for the first method is to have less records in case that these are really big databases - but still, you could "archive" old records by joining them in summaries or by some other way. What do you think?

• Unit testing a database connection and general questions on database-dependent code and unit testing

  - by dotnetdev

  Hi, If I have a method which establishes a database connection, how could this method be tested? Returning a bool in the event of a successful connection is one way, but is that the best way? From a testability method, is it best to have the connection method as one method and the method to get data back a seperate method? Also, how would I test methods which get back data from a database? I may do an assert against expected data but the actual data can change and still be the right resultset. EDIT: For the last point, to check data, if it's supposed to be a list of cars, then I can check they are real car models. Or if they are a bunch of web servers, I can have a list of existant web servers on the system, return that from the code under test, and get the test result. If the results are different, the data is the issue but the query not? THnaks

• Doxygen C++ comment string parser in python?

  - by Sebastian

  Does anybody know of a python module to parse a doxygen style C++ comment string? I mean a string like this (simple example): /** * A constructor. * A more elaborate description of the constructor. * @param param1 test1 * @param param2 test2 */ and I would like to extract the brief, the long description, the parameters, the return value etc. I'm currently doing this using string methods and regular expressions but my solution is not very robust. Alternatively does anybody know an easy to use parser lib that I can set up quickly? Thanks in advance

In my service I'd like to implement automatic logout of the user, if no service methods were invoked during a period of time (for example 20 minutes). I'm thinking about smth like that: Dictionary<User,TimeSpan> Inactivity When a service method is invoked i reset the TimeSpan. But what will happen, if 20 minutes pass, and I call the Logout method (which clears all User caches), and suddenly the User returns from lunch)) and presses a button in his Silverlight app? Obviously he'll get an error. Is there any way to avoid this, or all my concept is wrong? Maybe there's a better way to logout the user automatically?
