• Managing/Storing complex application form

  - by mickyjtwin

  I am developing an online application form, which can be of two categories, either domestic/international. Each different type has commong questions, and also specific questions. They are approx 6 pages/steps of questions. The application form can also be saved at the end of each step, and can be completed at a later date. Some questions will vary depending on answers to previous questions, so there are some complex business rules. In terms of storage of results, would it be best to store the answers in and XML field in SQL? What would be the best way to reference a question to an answer. There is no need for the form to be dynamic in rendering questions etc. e.g. <Application id="123" type="Domestic"> <Answers> <EmailAddress>[email protected]</EmailAddress> <HomePhone>555-5555</HomePhone> <Suburb>MySuburb</Suburb> <Guardians> <Guardian type="Mother"> <FirstName>Mom</FirstName> </Guardian> </Guardians> <Answers> </Application>

• Split large repo into multiple subrepos and preserve history (Mercurial)

  - by Andrew

  We have a large base of code that contains several shared projects, solution files, etc in one directory in SVN. We're migrating to Mercurial. I would like to take this opportunity to reorganize our code into several repositories to make cloning for branching have less overhead. I've already successfully converted our repo from SVN to Mercurial while preserving history. My question: how do I break all the different projects into separate repositories while preserving their history? Here is an example of what our single repository (OurPlatform) currently looks like: /OurPlatform ---- Core ---- Core.Tests ---- Database ---- Database.Tests ---- CMS ---- CMS.Tests ---- Product1.Domain ---- Product1.Stresstester ---- Product1.Web ---- Product1.Web.Tests ---- Product2.Domain ---- Product2.Stresstester ---- Product2.Web ---- Product2.Web.Tests ==== Product1.sln ==== Product2.sln All of those are folders containing VS Projects except for the solution files. Product1.sln and Product2.sln both reference all of the other projects. Ideally, I'd like to take each of those folders, and turn them into separate Hg repos, and also add new repos for each project (they would act as parent repos). Then, If someone was going to work on Product1, they would clone the Product1 repo, which contained Product1.sln and subrepo references to ReferenceAssemblies, Core, Core.Tests, Database, Database.Tests, CMS, and CMS.Tests. So, it's easy to do this by just hg init'ing in the project directories. But can it be done while preserving history? Or is there a better way to arrange this?

• JDBC/OSGi and how to dynamically load drivers without explicitly stating dependencies in the bundle?

  - by Chris

  Hi, This is a biggie. I have a well-structured yet monolithic code base that has a primitive modular architecture (all modules implement interfaces yet share the same classpath). I realize the folly of this approach and the problems it represents when I go to deploy on application servers that may have different conflicting versions of my library. I'm dependent on around 30 jars right now and am mid-way though bnding them up. Now some of my modules are easy to declare the versioned dependencies of, such as my networking components. They statically reference classes within the JRE and other BNDded libraries but my JDBC related components instantiate via Class.forName(...) and can use one of any number of drivers. I am breaking everything up into OSGi bundles by service area. My core classes/interfaces. Reporting related components. Database access related components (via JDBC). etc.... I wish for my code to be able to still be used without OSGi via single jar file with all my dependencies and without OSGi at all (via JARJAR) and also to be modular via the OSGi meta-data and granular bundles with dependency information. How do I configure my bundle and my code so that it can dynamically utilize any driver on the classpath and/or within the OSGi container environment (Felix/Equinox/etc.)? Is there a run-time method to detect if I am running in an OSGi container that is compatible across containers (Felix/Equinox/etc.) ? Do I need to use a different class loading mechanism if I am in a OSGi container? Am I required to import OSGi classes into my project to be able to load an at-bundle-time-unknown JDBC driver via my database module? I also have a second method of obtaining a driver (via JNDI, which is only really applicable when running in an app server), do I need to change my JNDI access code for OSGi-aware app servers?

• Replace System.Net.Mail.MailMessage with manually created message and send it

  - by DEH

  I am trying to send emails that will bounce to a known mailbox. I plan to use VERP. Unfortunately the System.Net.Mail.MailMessage object does not allow me to precisely set the From: and Sender: headers within my email - it forces the values so that the resulting email contains the phrase 'on behalf of', and does not allow me fine control over the relevant mime headers. I therefore plan to manually write mime email messages directly to the pickup directory so that I can independently control the From and Sender headers. My dev box is a Vista box and therefore does not have an SMTP server. I would like to configure the dev box so that I have an SMTP server running on it. I can then turn off the SMTP server, write messages to the pickup dir, then turn on the SMPT server and see how the individual emails that I have written will behave (some delivered, some bounced to a bounce handler on a different email domain, as dictated by the Sender). Two questions: 1. Can anyone recommend an SMTP server that will monitor a pickup directory? 2. If I set headers as follows; From:[email protected]; Sender:[email protected] then the recipient will see the email as having come from [email protected] ( and won't see any reference to [email protected]), but if the mail bounces then the NDR will be sent to [email protected]). It's a real pain to have to do this, but I can't see any way of using System.Net.Mail.MailMessage without it messing up my headers.

• How can I use System.Web.Caching.Cache in a Console application?

  - by Ron Klein

  Context: .Net 3.5, C# I'd like to have caching mechanism in my Console application. Instead of re-inventing the wheel, I'd like to use System.Web.Caching.Cache (and that's a final decision, I can't use other caching framework, don't ask why). However, it looks like System.Web.Caching.Cache is supposed to run only in a valid HTTP context. My very simple snippet looks like this: using System; using System.Web.Caching; using System.Web; Cache c = new Cache(); try { c.Insert("a", 123); } catch (Exception ex) { Console.WriteLine("cannot insert to cache, exception:"); Console.WriteLine(ex); } and the result is: cannot insert to cache, exception: System.NullReferenceException: Object reference not set to an instance of an object. at System.Web.Caching.Cache.Insert(String key, Object value) at MyClass.RunSnippet() So obviously, I'm doing something wrong here. Any ideas? Update: +1 to most answers, getting the cache via static methods is the correct usage, namely HttpRuntime.Cache and HttpContext.Current.Cache. Thank you all!

• Can I use Ninject ConstructorArguments with strong naming?

  - by stiank81

  Well, I don't know if "strong naming" is the right term, but what I want to do is as follows. Currently I use ConstructorArgument like e.g. this: public class Ninja { private readonly IWeapon _weapon; private readonly string _name; public Ninja(string name, IWeapon weapon) { _weapon = weapon; _name = name; } // ..more code.. } public void SomeFunction() { var kernel = new StandardKernel(); kernel.Bind<IWeapon>().To<Sword>(); var ninja = ninject.Get<Ninja>(new ConstructorArgument("name", "Lee")); } Now, if I rename the parameter "name" (e.g. using ReSharper) the ConstructorArgument won't update, and I will get a runtime error when creating the Ninja. To fix this I need to manually find all places I specify this parameter through a ConstructorArgument and update it. No good, and I'm doomed to fail at some point even though I have good test coverage. Renaming should be a cheap operation. Is there any way I can make a reference to the parameter instead - such that it is updated when I rename the parameter?

• Debug NAudio MP3 reading difference?

  - by Conrad Albrecht

  My code using NAudio to read one particular MP3 gets different results than several other commercial apps. Specifically: My NAudio-based code finds ~1.4 sec of silence at the beginning of this MP3 before "audible audio" (a drum pickup) starts, whereas other apps (Windows Media Player, RealPlayer, WavePad) show ~2.5 sec of silence before that same drum pickup. The particular MP3 is "Like A Rolling Stone" downloaded from Amazon.com. Tested several other MP3s and none show any similar difference between my code and other apps. Most MP3s don't start with such a long silence so I suspect that's the source of the difference. Debugging problems: I can't actually find a way to even prove that the other apps are right and NAudio/me is wrong, i.e. to compare block-by-block my code's results to a "known good reference implementation"; therefore I can't even precisely define the "error" I need to debug. Since my code reads thousands of samples during those 1.4 sec with no obvious errors, I can't think how to narrow down where/when in the input stream to look for a bug. The heart of the NAudio code is a P/Invoke call to acmStreamConvert(), which is a Windows "black box" call which I can't think how to error-check. Can anyone think of any tricks/techniques to debug this?

• How do I use foreach with QDomNodeList in Qt?

  - by Venemo

  Hi Everyone, I'm new to Qt and I'm learning something new every day. Currently, I'm developing a small application for my Nokia N900 in my free time. Everything is fine, I am able to compile and run Maemo applications on the device. I've just learned about the foreach keyword in Qt. (I know it is not in C++, so I didn't think about it until I accidentally stumbled upon a Qt doc that mentioned it.) So, I decided to change my quite annoying and unreadable loops to foreach, but I failed with this: QDomNodeList list = doc.lastChild().childNodes().at(1).firstChild().childNodes(); for (int x = 0; x < list.count(); x++) { QDomElement node = list.at(x).toElement(); // Do something with node } This is how I tried: foreach (QDomElement node, doc.lastChild().childNodes().at(1).firstChild().childNodes()) { // Do something with node } For some reason the above code doesn't even compile. I get cryptic error messages from the compiler. Could someone please explain to me how to get it right? If the foreach loop doesn't support QDomNodeList, is there a way of handling XML files that do support foreach?

• Using A Local file path in a Streamwriter object ASP.Net

  - by Nick LaMarca

  I am trying to create a csv file of some data. I have wrote a function that successfully does this.... Private Sub CreateCSVFile(ByVal dt As DataTable, ByVal strFilePath As String) Dim sw As New StreamWriter(strFilePath, False) ''# First we will write the headers. ''EDataTable dt = m_dsProducts.Tables[0]; Dim iColCount As Integer = dt.Columns.Count For i As Integer = 0 To iColCount - 1 sw.Write(dt.Columns(i)) If i < iColCount - 1 Then sw.Write(",") End If Next sw.Write(sw.NewLine) ''# Now write all the rows. For Each dr As DataRow In dt.Rows For i As Integer = 0 To iColCount - 1 If Not Convert.IsDBNull(dr(i)) Then sw.Write(dr(i).ToString()) End If If i < iColCount - 1 Then sw.Write(",") End If Next sw.Write(sw.NewLine) Next sw.Close() End Sub The problem is I am not using the streamwriter object correctly for what I trying to accomplish. Since this is an asp.net I need the user to pick a local filepath to put the file on. If I pass any path to this function its gonna try to write it to the directory specified on the server where the code is. I would like this to popup and let the user select a place on their local machine to put the file.... Dim exData As Byte() = File.ReadAllBytes(Server.MapPath(eio)) File.Delete(Server.MapPath(eio)) Response.AddHeader("content-disposition", String.Format("attachment; filename={0}", fn)) Response.ContentType = "application/x-msexcel" Response.BinaryWrite(exData) Response.Flush() Response.End() I am calling the first function in code like this... Dim emplTable As DataTable = SiteAccess.DownloadEmployee_H() CreateCSVFile(emplTable, "C:\\EmplTable.csv") Where I dont want to have specify the file loaction (because this will put the file on the server and not on a client machine) but rather let the user select the location on their client machine. Can someone help me put this together? Thanks in advance.

• How to get position of parent element - XSL

  - by joe

  What I wish I could do in xsl is the following, but unfortunatly parent/position() is not valid. XSL <xsl:template match="li"> <bullet> <xsl:apply-templates/> </bullet> <!-- todo: if this is the last bullet AND there are no more "p" tags, output footer --> <xsl:if test="count(ancestor::div/*) = parent/position()"> <footer/> </xsl:if> </xsl:template> XML <html> <div> <p>There is an x number of me</p> <p>There is an x number of me</p> <p>There is an x number of me</p> <ul> <li>list item</li> <li>list item</li> <li>list item</li> <li>list item</li> <li>list item</li> </ul> </div> </html> Anyone have any ideas how to figure out this problem from WITHIN my template match for li?

• Random point on VideoDisplay isn't accurate enough

  - by Mike

  For a schoolassigment me and some buddies of mine are creating an application that is showing many similarities with the C-Mon & Kypski musicvideo on www.oneframeoffame.com. The application is being developed in Flex. We want to get a random point of a clip, let it pause so a user can mimic the pose and make a snapshot out of it. What i managed to do is get a random point of the movie. I did this by getting a random value between 0 and de total duration of the movie. But what i didn't managed to do is let the screen pause on every 24st of a frame. As the movie concist out of 24FPS. It looks like the the random value of the movie that is being requested is being rounded by the movie itself. As example: There appears to be no difference between the frames requested at 2.40 or 2.41. It appears it got something to do with keyframing i've read on the Adobe® Flex™ 3.5 Language Reference. The movie is a FLV file and i use the VideoDisplay object to display the movie. Does someone is familiar with this or knows a solution to my problem? Thanks in advance

• FLEX: the custom component is still a Null Object when I invoke its method

  - by Patrick

  Hi, I've created a custom component in Flex, and I've created it from the main application with actionscript. Successively I invoke its "setName" method to pass a String. I get the following run-time error (occurring only if I use the setName method): TypeError: Error #1009: Cannot access a property or method of a null object reference. I guess I get it because I'm calling to newUser.setName method from main application before the component is completely created. How can I ask actionscript to "wait" until when the component is created to call the method ? Should I create an event listener in the main application waiting for it ? I would prefer to avoid it if possible. Here is the code: Main app ... newUser = new userComp(); //newUser.setName("name"); Component: <?xml version="1.0" encoding="utf-8"?> <mx:VBox xmlns:mx="http://www.adobe.com/2006/mxml" width="100" height="200" > <mx:Script> <![CDATA[ public function setName(name:String):void { username.text = name; } public function setTags(Tags:String):void { } ]]> </mx:Script> <mx:HBox id="tagsPopup" visible="false"> <mx:LinkButton label="Tag1" /> <mx:LinkButton label="Tag2" /> <mx:LinkButton label="Tag3" /> </mx:HBox> <mx:Image source="@Embed(source='../icons/userIcon.png')"/> <mx:Label id="username" text="Nickname" visible="false"/> </mx:VBox> thanks

• Expression Tree with Property Inheritance causes an argument exception

  - by Adam Driscoll

  Following this post: link text I'm trying to create an expression tree that references the property of a property. My code looks like this: public interface IFoo { void X {get;set;} } public interface IBar : IFoo { void Y {get;set;} } public interface IFooBarContainer { IBar Bar {get;set;} } public class Filterer { //Where T = "IFooBarContainer" public IQueryable<T> Filter<T>(IEnumerable<T> collection) { var argument = Expression.Parameter(typeof (T), "item"); //... //where propertyName = "IBar.X"; PropertyOfProperty(argument, propertyName); } private static MemberExpression PropertyOfProperty(Expression expr, string propertyName) { return propertyName.Split('.').Aggregate<string, MemberExpression>(null, (current, property) => Expression.Property(current ?? expr, property)); } } I receive the exception: System.ArgumentException: Instance property 'X' is not defined for type 'IBar' ReSharper turned the code in the link above into the condensed statement in my example. Both forms of the method returned the same error. If I reference IBar.Y the method does not fail.

• Binding event handlers to specific elements, using bubbling (JavaScript/jQuery)

  - by Bungle

  I'm working on a project that approximates the functionality of Firebug's inspector tool. That is, when mousing over elements on the page, I'd like to highlight them (by changing their background color), and when they're clicked, I'd like to execute a function that builds a CSS selector that can be used to identify them. However, I've been running into problems related to event bubbling, and have thoroughly confused myself. Rather than walk you down that path, it might make sense just to explain what I'm trying to do and ask for some help getting started. Here are some specs: I'm only interested in elements that contain a text node (or any descendant elements with text nodes). When the mouse enters such an element, change its background color. When the mouse leaves that element, change its background color back to what it was originally. When an element is clicked, execute a function that builds a CSS selector for that element. I don't want a mouseover on an element's margin area to count as a mouseover for that element, but for the element beneath (I think that's default browser behavior anyway?). I can handle the code that highlights/unhighlights, and builds the CSS selector. What I'm primarily having trouble with is efficiently binding event handlers to the elements that I want to be highlightable/clickable, and avoiding/stopping bubbling so that mousing over a (<p>) element doesn't also execute the handler function on the <body>, for example. I think the right way to do this is to bind event handlers to the document element, then somehow use bubbling to only execute the bound function on the topmost element, but I don't have any idea what that code looks like, and that's really where I could use help. I'm using jQuery, and would like to rely on that as much as possible. Thanks in advance for any guidance!

• Making ANTLR generated class files into one jar file.

  - by prosseek

  With ANTLR, I get some java class files after compilation. And I need to make all the class files into one jar file. I make manifest.mf file that has one line "Main-class: Test" to indicate the main file. I run 'jar cmf manifest.mf hello.jar *.class' to get hello.jar file. But when I try to run 'java -jar hello.jar', I get the following error messages. $ java -jar hello.jar Exception in thread "main" java.lang.NoClassDefFoundError: Test Caused by: java.lang.ClassNotFoundException: Test at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:315) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:330) at java.lang.ClassLoader.loadClass(ClassLoader.java:250) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:398) What's wrong?

• Placement/Positioning/Alignment of UIScrollView w.r.t. length of Title NSString

  - by Shoaibi

  I have a scenario where i show stuff like: ----------------------------------- titleview (UITextView) ______________ tArea (UIScrollView) ttextview (UITextView) ----------------------------------- Now here is the condition: Length of titleview's text is dynamic, varies based on user input. Because of the condition I have trouble placing tArea e.g. UIScrollView on the screen, it either appears way too below than the titleview, or overlaps it. Previously what i did: Count the number of characters in titleview.text.length and divide them by 27 (e.g. characters in one line when using boldSystemFontOfSize:20) and multiply by 10 to get the starting X of tArea e.g. UIScrollView. But that sucked. Because i had to duplicate code for rotation to landscape. What do i have now? : CGSize titlesize = [title sizeWithFont:[UIFont systemFontOfSize:20] constrainedToSize:CGSizeMake(5, 90) lineBreakMode:UILineBreakModeWordWrap]; ttitleview = [[UITextView alloc] initWithFrame:CGRectMake(5, 5, 310,titlesize.height)]; ttitleview.text = title; ttitleview.font = [UIFont boldSystemFontOfSize:20]; ttitleview.backgroundColor = [UIColor clearColor]; ttitleview.editable = NO; [self.view addSubview:ttitleview]; CGSize textsize = [ttext sizeWithFont:[UIFont systemFontOfSize:20] constrainedToSize:CGSizeMake(5, 350) lineBreakMode:UILineBreakModeWordWrap]; tArea = [[UIScrollView alloc] initWithFrame:CGRectMake(5, titlesize.height, 310, 230)]; tArea.contentSize = CGSizeMake(310, textsize.height+20); tArea.pagingEnabled = FALSE; tArea.scrollEnabled = TRUE; tArea.backgroundColor = [UIColor clearColor]; [self.view addSubview:tArea]; ttextview = [[UITextView alloc] initWithFrame:CGRectMake(0, 0, 310, textsize.height + 20)]; ttextview.text = ttext; ttextview.font = [UIFont systemFontOfSize:20]; ttextview.backgroundColor = [UIColor clearColor]; ttextview.editable = NO; [tArea addSubview:ttextview]; But its no use. Looking for an elegant solution than this.

• How can I highlight the corresponding titles of clicked links?

  - by danielle

  I'm writing an XSL file that contains a side-nav menu with a list of links. When the user clicks on one of the links, the page jumps to the corresponding table of information for that link. How can I make it so that when the link is clicked, the title of that table (not the link itself) is highlighted? It should also un-highlight if another link is clicked. Here is the menu of links: <div onclick = "highlight(this);" onblur = "undoHighlight(this);"> <a href = "#{generate-id(.)}"> <xsl:value-of select = "."/> (<xsl:value-of select = "count(../n1:entry)"/>) </a> </div> This is the javascript for the highlight/undoHighlight functions: function highlight(link) { undoHighlight(link) link.style.background = "red"; } function undoHighlight(link) { link.style.background = "white"; } Any help would be appreciated. Thanks in advance!

• Export database data to csv from view by date range asp.net mvc3

  - by Benjamin Randal

  I am trying to find a way to export data from my database and save it as a .csv file. Ideally the user will be able to select a date range on a view, which will display the data to be exported, then the user can click an "export to CSV" link. I've done quite a bit of searching and but have not found much specific enough to help me step through the process. Any help would be great. I would like to export data from this database model... { public class InspectionInfo { [Key] public int InspectionId { get; set; } [DisplayName("Date Submitted")] [DataType(DataType.Date)] // [Required] public DateTime Submitted { get; set; } [DataType(DataType.MultilineText)] [MaxLength(1000)] // [Required] public string Comments { get; set; } // [Required] public Contact Contact { get; set; } [ForeignKey("Contact")] public Int32 ContactId { get; set; } [MaxLength(100)] public String OtherContact { get; set; } I have a service for search also, just having difficulty implementing public SearchResults SearchInspections(SearchRequest request) { using (var db = new InspectionEntities()) { var results = db.InspectionInfos .Where( i=> ( (null == request.StartDate || i.Submitted >= request.StartDate.Value) && (null == request.EndDate || i.Submitted <= request.EndDate.Value) ) ) .OrderBy(i=>i.Submitted) .Skip(request.PageSize*request.PageIndex).Take(request.PageSize); return new SearchResults{ TotalResults=results.Count(), PageIndex=request.PageIndex, Inspections=results.ToList(), SearchRequest=request }; } }

• Drupal: Template Files, Modules and Content Types for Advanced Theme

  - by theandym

  Intro I am in the process of trying to convert my first HTML/CSS design into a theme for Drupal. I have used ModX for quite a few designs and appreciate the ability to create different page templates and custom variables to be assigned to those templates. However I seem to be having some issues making the transition. The site I am working on theming in Drupal is for a real estate agent. Each page/section will have a different set of content associated with it and will need to display only that content. For example, there will be a page for current listings, each of which will be formatted by a custom content type. However, when I call the content on the home page (or on other pages) I do not want to see this listing data. Layout The layout of the site and the regions associated with each page/section is as follows: Home Spotlight Featured 1 Featured 2 About Spotlight Bios - Profiles of each agent (each will be a node with name, contact info, pic, etc) listed on the page; multiple nodes listed Sidebar Listings Spotlight Listings - Profiles of properties (each will be a node with locations, basic info, pic, etc) listed on the page; multiple nodes listed Sidebar Services Spotlight Content - general paragraph text area Sidebar News/Blog News/Blog Items - List of stories with summaries and links to full article Sidebar Each page/section will use the same header and footer. Issue I have done some reading on Drupal, custom content types (and CCK), Views, and Pathauto. However I have not been able to get a clear picture of how to put it all together to accomplish what I am attempting. What I really would like to know is which modules to use, how best to use them, which elements I need to use where, and what template files I should be using to theme the elements I need to use. Any help or reference to useful resources would be much appreciated.

• ASP.Net HttpModule List<> content

  - by test

  We have created an http module that loads data on initialize into a list, and uses that list on every endrequest event of application. However we got a null reference exception on the module at endRequest event complaining that the content is null. Yet we are sure that at module initialization we have put non-null objects correctly. How is this possible? Any ideas? Thanks in advance. The place where i fill the data into the list what named as "Pages" : using (SqlDataReader reader = cmd.ExecuteReader()) { while (reader.Read()) { LandingPageDetails details = new LandingPageDetails(); details.DomainId = Convert.ToInt32(reader["DomainId"]); details.PageId = Convert.ToInt32(reader["TrackingPageId"]); details.PageAddress = Convert.ToString(reader["PageAddress"]); if (!string.IsNullOrEmpty(details.PageAddress)) { Pages.Add(details); } } } // Find the related record on EndRequesst event LandingPageDetails result = Pages.Find ( delegate(LandingPageDetails current) { return current.PageAddress.Equals(url, StringComparison.InvariantCultureIgnoreCase); } ); The line what we get the error return current.PageAddress.Equals(url, StringComparison.InvariantCultureIgnoreCase); "current" is the null object P.S : It works properly, but one day later contents become null. Possibly, there is something wrong on IIS. Our server is Windows 2003, IIS 6.0

• How are Scala closures transformed to Java objects?

  - by iguana

  I'm currently looking at closure implementations in different languages. When it comes to Scala, however, I'm unable to find any documentation on how a closure is mapped to Java objects. It is well documented that Scala functions are mapped to FunctionN objects. I assume that the reference to the free variable of the closure must be stored somewhere in that function object (as it is done in C++0x, e.g.). I also tried compiling the following with scalac and then decompiling the class files with JD: object ClosureExample extends Application { def addN(n: Int) = (a: Int) => a + n var add5 = addN(5) println(add5(20)) } In the decompiled sources, I see an anonymous subtype of Function1, which ought to be my closure. But the apply() method is empty, and the anonymous class has no fields (which could potentially store the closure variables). I suppose the decompiler didn't manage to get the interesting part out of the class files... Now to the questions: Do you know how the transformation is done exactly? Do you know where it is documented? Do you have another idea how I could solve the mystery?

• How do I correctly modify a custom cocoa framework?

  - by Septih

  Hello, I'm working with the very-useful ID3 framework in my cocoa project. There's one tiny thing I'd like to modify in it, but I can't seem to get the changes I've made to apply to the built framework. The source code provided with the framework comes with an Xcode project, so I've opened that up and for testings sake put an NSLog(@"hello"); in. It's definetly in a place where it will be called and there are other NSLog() calls in the framework that show up so it's not just console output being supressed. To build the framework once modified I've first cleaned the build folder, made sure that it's actually removed the files, and then built it. Then in the Xcode project I'm using the framework in, I've deleted the old reference and added a new one to the framework that's freshly built. Running my project with the newly build framework doesn't call the modified framework code. I've tried with both the Development and Deployment builds that are part of the framework Xcode project. My gut instinct is that the executable that the framework code is compiled into is being cached somehow. But as I'm fairly unfamiliar with the workings of frameworks, I'm not really sure where to look.
