• What features of Scala cannot be translated to Java?

  - by Paul

  The Scala compiler compiles direct to Java byte code (or .NET CIL). Some of the features of Scala could be re-done in Java straightforwardly (e.g. simple for comprehensions, classes, translating anonymous/inner functionc etc). What are the features that cannot be translated that way? That is presumably mostly of academic interest. More usefully, perhaps, what are the key features or idioms of Scala that YOU use that cannot be easily represented in Java? Are there any the other way about? Things that can be done straightforwardly in Java that have no straightforward equivalent in Scala? Idioms in Java that don't translate?

• Why does Perl complain "Can't modify constant item in scalar assignment"?

  - by joe

  I have this Perl subroutine that is causing a problem: sub new { my $class = shift; my $ldap_obj = Net::LDAP->new( 'test.company.com' ) or die "$@"; my $self = { _ldap = $ldap_obj, _dn ='dc=users,dc=ldap,dc=company,dc=com', _dn_login = 'dc=login,dc=ldap,dc=company,dc=com', _description ='company', }; # Print all the values just for clarification. bless $self, $class; return $self; } what is wrong on this code : i got this error Can't modify constant item in scalar assignment at Core.pm line 12, near "$ldap_obj,"

• Facebook Open Graph - Grab how many times a page has been liked?

  - by DoMx

  I have a site that allows users to create a saying and then users "like" those sayings on Facebook. http://www.likeylikey.net/ I got a friend to throw up this simple code in less than 2 hours so it's basic. He knows little to nothing regarding the Open Graph API. Basically, I want to know how I can programmatically store how many times a page has been liked so I can list a "Top 10, most liked pages" list. Right now the index shows a list of all created pages and now I just wish to show the 10 most liked but I need a way of pulling that information from Facebook. Is this possible?

• Need to get to the foreign keys of an entity marked as "Deleted" for auditing

  - by Abhijeet Patel

  I'm using v1 of EF(.NET 3.5 SP1). I'm subscribing to the SavingChanges event of the ObjectContext wherein I audit deletes for a particular entity type. I need to get to the foreign keys of the entity being deleted i.e EntityKeys of the related entities (RelatedEnds) but the EntityKeys of the related entities are nulls. Is there any way to get to the foreign keys of an entity which has been marked for deletion? Does EF null out the EntityKeys of all RelatedEnds for an entity which has been marked for deletion? If so, is there a way I can get hold of the foreign keys?

• Universal control - simple question about dock and anchor

  - by Vytas999

  I use Visual Studio .NET to develop internal applications. I create a Windows control that will display custom status bar information. Different developers will use the control to display the same information in many different applications. The control must always be displayed at the bottom of the parent form in every application. It must always be as wide as the form. When the form is resized, the control should be resized and repositioned accordingly. How should I do that in the best way and why? A)Create a property to allow the developers to set the Dock property of the control. Set the default value of the property to AnchorStyle.Bottom. B) Create a property to allow the developer to set the Anchor property of the control. Set the default value of the property to AnchorStyle.Bottom.

• Sbyte[] vs byte[][] using methods

  - by blgnklc

  It is written byte[][] getImagesForFields(java.lang.String[] fieldnames) Gets an array of images for the given fields. On the other hand, as long as I use the method in the web application project built on asp.net 2.o using c#; the provided web method declared above, returns sbyte; Have a look my code below; formClearanceService.openSession(imageServiceUser); formClearanceService.prepareInstance(formId); byte[][] fieldImagesList = formClearanceService.getImagesForFields(fieldNames); formClearanceService.closeSession(); thus I get the following error: Cannot implicitly convert type 'sbyte[]' to 'byte[][]' So now, 1- should I ask the web service provider what is going on? or 2- any other way that can use the sbyte as I was suppose to use byte[][] like following using: byte[] ssss = fieldImagesList [0]..

• Composite primary keys in N-M relation or not?

  - by BerggreenDK

  Lets say we have 3 tables (actually I have 2 at the moment, but this example might illustrate the thought better): [Person] ID: int, primary key Name: nvarchar(xx) [Group] ID: int, primary key Name: nvarchar(xx) [Role] ID: int, primary key Name: nvarchar(xx) [PersonGroupRole] Person_ID: int, PRIMARY COMPOSITE OR NOT? Group_ID: int, PRIMARY COMPOSITE OR NOT? Role_ID: int, PRIMARY COMPOSITE OR NOT? Should any of the 3 ID's in the relation PersonGroupRole be marked as PRIMARY key or should they all 3 be combined into one composite?? whats the real benefit of doing it or not? I can join anyways as far as I know, so Person JOIN PersonGroupRole JOIN Group gives me which persons are in which Groups etc. I will be using LINQ/C#/.NET on top of SQL-express and SQL-server, so if there is any reasons regarding language/SQL that might make the choice more clear, thats the platform I ask about. Looking forward to see what answers pops up, as I have thought of these primary keys/indexes many times when making combined ones.

• 'Advanced' Console Application

  - by keynesiancross

  Hi all, I'm not sure if this question has been answered elsewhere and I can't seem to find anything through google that isn't a "Hello World" example... I'm coding in C# .NET 4.0. I'm trying to develop a console application that will open, display text, and then wait for the user to input commands, where the commands will run particular business logic. For example: If the user opens the application and types "help", I want to display a number of statements etc etc. I'm not sure how to code the 'event handler' for user input though. Hopefully this makes sense. Any help would be much appreciated! Cheers.

• Windows equivalent of inb(), outb(), low level i/o

  - by Sebastian Dwornik

  I have some Linux code that monitors our hardware by collecting temperatures, voltages, and fan speeds, from the motherboard using inb(), outb(), inl(), etc. low level i/o functions. My challenge is to port that code over to run under Windows as a simple console app. But am puzzled in what functions Win32 (or .NET) provide that allow me permission to access direct memory mapped ports. I don't want to code a system driver either. My Windows tool preference is VS2008. (fyi) Is this possible?

• error calling c# com interop dll

  - by aF

  Hello, I have a python project that calls a c++ dll that calls a c# dll. I wanted all to run without installing visual studio 2008. I allready made the c++ part by installing Visual C++ 2008 SP1 Redistributable Package (x86) and I also installed .net framework 3.5. But now, when I call a function from c++ dll (and this one calls its correspondent in c#), it gives me this error: Traceback (most recent call last): File "C:\Users\Public\SoundLog\Code\Código Python\SoundLog\SoundLog.py", line 821, in OnStart Auxiliar.DataCollection.start(self) File "C:\Users\Public\SoundLog\Code\Código Python\SoundLog\Auxiliar\DataCollection.py", line 68, in start SoundLogDLL.run() File "C:\Users\Public\SoundLog\Code\Código Python\SoundLog\Auxiliar\SoundLogDLL.py", line 61, in run return apiRun() WindowsError: exception code 0xe0434f4d This works where I've installed full VS2008 pro version. What am I missing and what can I do to solve this?

• css override not working?

  - by Karin

  I have three tabs that change styles when clicked. class="active" gives the tab the same background as the tab content, while class="inactive" has another color. My problem is the text on the tabs, something's weird with the CSS. The default state of class="active" looks as it should, while the inactive tabs are underlined even though my CSS says text-decoration: none !important; and the clicked active tab text becomes extra bold (or maybe it's a shadow). Please look at my fiddle: http://jsfiddle.net/m8wQM/170/

• Region or ItemsSource for large data set in ListBox

  - by Ryan

  I'm having trouble figuring out what the best solution is given the following situation. I'm using Prism 4.1, MEF, and .Net 4.0. I have an object Project that could have a large number (~1000) of Line objects. I'm deciding whether it is better to expose an ObservableCollection<LineViewModel> from my ProjectViewModel and manually create the Line viewmodels there OR set the ListBox as it's own region and activate views that way. I'd still want my LineViewModel to have Prism's shared services (IEventAggregator, etc.) injected, but I don't know how to do that when I manually create the LineViewModel. Any suggestions or thoughts?

• C# move file as soon as it becomes available.

  - by m0s

  Hi, I need to accomplish the following task: Attempt to move a file. If file is locked schedule for moving as soon as it becomes available. I am using File.Move which is sufficient for my program. Now the problems are that: 1) I can't find a good way to check if the file I need to move is locked. I am catching System.IO.IOException but reading other posts around I discovered that the same exception may be thrown for different reasons as well. 2) Determining when the file gets unlocked. One way of doing this is probably using a timer/thread and checking the scheduled files lets say every 30 seconds and attempting to move them. But I hope there is a better way using FileSystemWatcher. This is a .net 3.5 winforms application. Any comments/suggestions are appreciated. Thanks for attention.

• how could I pass closure problems in order to increment a global var

  - by hyptos

  I have a simple goal, I would like to increment a variable but I'm facing the closure problem. I've read why this s happening here How do JavaScript closures work? But I can't find the solution to my problem :/ let's assume this part of code I took from the link. function say667() { // Local variable that ends up within closure var num = 666; var sayAlert = function() { alert(num); //incrementation } num++; return sayAlert; } I would like to increment num within the function and to keep the changes to num. How could I do that ? Here is the JsFiddle where I have my problem, I can't figure out how to increment my totalSize and keep it. http://jsfiddle.net/knLbv/2/ I don't want a local variable that ends up with closure.

• Data driven charts and graphs from xml to svg

  - by garymlewis

  I asked this question a week ago, but did not do a good job of describing the problem. Here's a second attempt. I'd like to produce data-driven charts, graphs, and other data visualizations, starting with data in an xml database and ending up with the visualizations as SVG. Here's an example from the W3C. It uses Javascript to create a stacked bar chart as SVG from xml. I'd like to do something similar but use a graphics library (or ???) instead of js to handle the construction of axes, labels, titles, data points, etc. My question, then: what are the options that I should consider ... things like Raphael I suppose, but initially I'd like to cast a wide net and look at many different options. My experience is all with static data visualizations using statistics packages like R, but eventually I'd like to create interactive data visualizations with html5/css3/svg. Any help would be much appreciated. Thanks.

• Cleanest Way to Invoke Cross-Thread Events

  - by Nick

  I find that the .NET event model is such that I'll often be raising an event on one thread and listening for it on another thread. I was wondering what the cleanest way to marshal an event from a background thread onto my UI thread is. Based on the community suggestions, I've used this: // earlier in the code mCoolObject.CoolEvent+= new CoolObjectEventHandler(mCoolObject_CoolEvent); // then private void mCoolObject_CoolEvent(object sender, CoolObjectEventArgs args) { if (InvokeRequired) { CoolObjectEventHandler cb = new CoolObjectEventHandler( mCoolObject_CoolEvent); Invoke(cb, new object[] { sender, args }); return; } // do the dirty work of my method here }

• Why does this jQuery dropdown menu display subcategory selections only for certain top-level categories?

  - by chunkymonkey

  I'm trying to implement a dropdown menu based on a jQuery plugin from Filament Group: http://jsfiddle.net/chunkymonkey/Pr8k4/ What I am having difficulty fixing is a bug where certain categories can be expanded to show their subcategories while others show nothing when opened up. For example: Alternative Rock can be expanded to show its multiple subcategories . . . BUT . . . World Music, which has equally many subcategories, shows no subcategories when expanded. I would be very grateful if anyone could help me figure out what's causing this. Thanks. UPDATE: Just noticed this problem may be Chrome-specific(??). I just tested it in IE8 and Firefox and it seems to work correctly in both.

• Changing gmail Settings with Ruby

  - by Technocrat

  I need to configure my gmail account(s) programmatically with Ruby. I checked out the apps api and it looks like the simplest possible solution would be to use ClientLogin for logging in and a simple XML PUT for changing the forwarding setting, for example. I wrote a little test script like so: http://gist.github.com/373457 It would appear that the call to ClientLogin works because it comes back with an Auth= token. When it sends the PUT request to google, however, it comes back with a RestClient::Unauthorized exception. I rewrote the script with pure net/https and it turns out the message I'm getting is invalid token, yet I can't figure out what is wrong with my token. Can anyone else see it?

• What frameworks exist for data subscription and update?

  - by Timothy Pratley

  There is one server with multiple clients. The clients are viewing subsets of the servers entire data. If the data that a client is viewing changes, the client should be informed of the changes so that it displays the current data. Example: Two clients are viewing a list of users in an administration screen. One client adds a new user to the list and modifies the permissions of another user. The other client sees the changes propagated to their view. In the client side code I would like the users list to be updated by the framework itself, raising changed events such that it will be redrawn - similar to 'cells' or dataflow. I am looking specifically for a .NET or java implementation.

• Can log4net appenders be defined in their own XML files?

  - by ladenedge

  I want to define a handful of (ADO.NET) appenders in my library, but allow users of my library to configure the use of those appenders. Something like this seems to be what I want: XmlConfigurator.Configure(appenderStream1); XmlConfigurator.Configure(appenderStream2); XmlConfigurator.Configure(); But that doesn't seem work, in spite of the debug output containing messages like this: Configuration update mode [Merge]. What is the right way to do this? Or, is there an alternative to asking users to duplicate large chunks of XML configuration?

• What is the purpose of this delegate usage?

  - by Kev

  Whilst poking around some code in .NET Reflector in an app I don't have the source code for I found this: if (DeleteDisks) { using (List<XenRef<VDI>>.Enumerator enumerator3 = list.GetEnumerator()) { MethodInvoker invoker2 = null; XenRef<VDI> vdiRef; while (enumerator3.MoveNext()) { vdiRef = enumerator3.Current; if (invoker2 == null) { // // Why do this? // invoker2 = delegate { VDI.destroy(session, vdiRef.opaque_ref); }; } bestEffort(ref caught, invoker2); } } } if (caught != null) { throw caught; } private static void bestEffort(ref Exception caught, MethodInvoker func) { try { func(); } catch (Exception exception) { log.Error(exception, exception); if (caught == null) { caught = exception; } } } Why not call VDI.destroy() directly. Is this just a way of wrapping the same pattern of try { do something } catch { log error } if it's used a lot?

• Infor PM (Business Intelligence solution)

  - by Andrew

  We are currently implementing the commercial Infor PM (Performance Management) package as a business intelligence tool. Infor PM website It is apparently used by over 1,000 companies around the world, but I have found scant information about it on the net except for what's on their own website. It covers the whole range of data warehousing and BI functions with: an OLAP environment an ETL tool a report writer (called Application Studio) an add-on to Excel to connect to the data in the cubes through a pivot table etc Does anyone have any experience with using this package? How does it compare to the big players in BI (Cognos, Microsoft SSAS, Business Objects, etc). Any pitfalls I should know about? On the other hand, does it do anything better than its competitors?
