• No internet access when using static IP

  - by Endy Tjahjono

  I have just upgraded to Windows 8.1, and after the upgrade process is finished, I can't connect to internet. I tried running the "Troubleshoot problems": It concluded that DHCP needs to be activated: I let it activate DHCP, and I got internet connection back. The problem is I want to set this PC to a certain IP address (the IP address that it has been using all this time). I am also using Hyper-V, which I suspect has something to do with this problem. After I regained internet connection, I tried running one of my Hyper-V VM. From inside the VM I can connect to internet. That VM has static IP address. I also noticed that in "Control Panel\Network and Internet\Network Connections", I usually have a network connection called vEthernet (Realtek PCIe GBE Family Controller Virtual Switch). I didn't find it there after upgrade. How do I set my PC to a static IP while retaining internet access in Windows 8.1? EDIT I have managed to recreate vEthernet (Realtek PCIe GBE Family Controller Virtual Switch) by unchecking Allow management operating system to share this network adapter in Hyper-V's Virtual Switch Manager and then checking it again. But when I changed the adapter to use static IP, it still can't connect to internet.

• Using interface classes and non-virtual interface idiom in C++

  - by andreas buykx

  Hi all, In C++ an interface can be implemented by a class with all its methods pure virtual: class IFoo { public: virtual void method() = 0; }; Now I want to implement this interface by a hierarchy of classes: class FooBase : public IFoo // implement interface IFoo { public: void method(); // calls methodImpl; private: virtual void methodImpl(); }; For the class hierarchy I would like to use the non-virtual interface (NVI) idiom, to deny derived classes the possibility of overriding the common behavior implemented in FooBase::method(), but it seems that all derived classes have the opportunity to override the FooBase::method() because it is declared in the interface class. Is my observation correct? And if so are there other options to both use interface classes and the NVI idiom?

• Grails: Services VS Groovy classes

  - by Olexandr

  Documentation says: The Grails team discourages the embedding of core application logic inside controllers, as it does not promote re-use and a clean separation of concerns. I have one API controller and a few Groovy classes in src/groovy folder. Those classes just implements my application logic so actions in API controller works in this way: //index page def index = { render new IndexApi().index(params) as JSON } I'm curious - is there any reason to move my application logic from plain groovy classes into services ?

• Generating ActionScript value objects from middle-tier Java classes

  - by eli

  In a Flex / Java app stack using remoting (via BlazeDS), classes to hold data passed back and forth between client and server need to be maintained in both the client (in ActionScript) and server (in Java). I want a way to maintain theses classes in Java only, and have the corresponding ActionScript value object classes generated by the build process.

• How to associate static entity instances in a Session without database retrieval

  - by Michael Hedgpeth

  I have a simple Result class that used to be an Enum but has evolved into being its own class with its own table. public class Result { public static readonly Result Passed = new Result(StatusType.Passed) { Id = [Predefined] }; public static readonly Result NotRun = new Result(StatusType.NotRun) { Id = [Predefined] }; public static readonly Result Running = new Result(StatusType.Running) { Id = [Predefined] }; } Each of these predefined values has a row in the database at their predefined Guid Id. There is then a failed result that has an instance per failure: public class FailedResult : Result { public FailedResult(string description) : base(StatusType.Failed) { . . . } } I then have an entity that has a Result: public class Task { public Result Result { get; set; } } When I save a Task, if the Result is a predefined one, I want NHibernate to know that it doesn't need to save that to the database, nor does it need to fetch it from the database; I just want it to save by Id. The way I get around this is when I am setting up the session, I call a method to load the static entities: protected override void OnSessionOpened(ISession session) { LockStaticResults(session, Result.Passed, Result.NotRun, Result.Running); } private static void LockStaticResults(ISession session, params Result[] results) { foreach (var result in results) { session.Load(result, result.Id); } } The problem with the session.Load method call is it appears to be fetching to the database (something I don't want to do). How could I make this so it does not fetch the database, but trusts that my static (immutable) Result instances are both up to date and a part of the session?

• Generate EF4 POCO classes first time only

  - by Jaxidian

  The problem I'm having is, using the POCO templates, generating my POCO classes the first time only and not overwriting them when the templates are re-ran. I know this sounds hokey and the reason is that I'm actually changing these templates and trying to generate metadata classes rather than the actual POCO classes, but these metadata classes will be hand-edited and I want to keep those edits in the future but still regenerate a certain amount of it. I have it all working exactly as I want except for the regeneration of the files. I have looked into T4 and it seems that there is a flag to do just this (see the Output.PreserveExistingFile property) but I don't understand where/how to set this flag. If you can tell me where/how to set this in the default POCO templates, then I think that's all I really need. Thanks!! :-)

• Objective-C: Getting the True Class of Classes in Class Clusters

  - by TechZen

  Recently while trying to answer a questions here, I ran some test code to see how Xcode/gdb reported the class of instances in class clusters. (see below) In the past, I've expected to see something like: PrivateClusterClass:PublicSuperClass:NSObject Such as this (which still returns as expected): NSPathStore2:NSString:NSObject ... for a string created with +[NSString pathWithComponents:]. However, with NSSet and subclass the following code: - (void)applicationDidFinishLaunching:(UIApplication *)application { NSSet *s=[NSSet setWithObject:@"setWithObject"]; NSMutableSet *m=[NSMutableSet setWithCapacity:1]; [m addObject:@"Added String"]; NSMutableSet *n = [[NSMutableSet alloc] initWithCapacity:1]; [self showSuperClasses:s]; [self showSuperClasses:m]; [self showSuperClasses:n]; [self showSuperClasses:@"Steve"]; } - (void) showSuperClasses:(id) anObject{ Class cl = [anObject class]; NSString *classDescription = [cl description]; while ([cl superclass]) { cl = [cl superclass]; classDescription = [classDescription stringByAppendingFormat:@":%@", [cl description]]; } NSLog(@"%@ classes=%@",[anObject class], classDescription); } ... outputs: // NSSet *s NSCFSet classes=NSCFSet:NSMutableSet:NSSet:NSObject //NSMutableSet *m NSCFSet classes=NSCFSet:NSMutableSet:NSSet:NSObject //NSMutableSet *n NSCFSet classes=NSCFSet:NSMutableSet:NSSet:NSObject // NSString @"Steve" NSCFString classes=NSCFString:NSMutableString:NSString:NSObject The debugger shows the same class for all Set instances. I know that in the past the Set class cluster did not return like this. What has changed? (I suspect it is a change in the bridge from Core Foundation.) What class cluster report just a generic class e.g. NSCFSet and which report an actual subclass e.g. NSPathStore2? Most importantly, when debugging how do you determine the actual class of a NSSet cluster instance?

• How does static code run with multiple threads?

  - by Krisc

  I was reading http://stackoverflow.com/questions/1511798/threading-from-within-a-class-with-static-and-non-static-methods and I am in a similar situation. I have a static method that pulls data from a resource and creates some runtime objects based on the data. static class Worker{ public static MyObject DoWork(string filename){ MyObject mo = new MyObject(); // ... does some work return mo; } } The method takes awhile (in this case it is reading 5-10mb files) and returns an object. I want to take this method and use it in a multiple thread situation so I can read multiple files at once. Design issues / guidelines aside, how would multiple threads access this code? Let's say I have something like this... class ThreadedWorker { public void Run() { Thread t = new Thread(OnRun); t.Start(); } void OnRun() { MyObject mo = Worker.DoWork("somefilename"); mo.WriteToConsole(); } } Does the static method run for each thread, allowing for parallel execution?

• static array in c++ forgets its size

  - by Karel Bílek

  In this small example, c++ forgets size of an array, passed to a constructor. I guess it is something simple, but I cannot see it. In classes.h, there is this code: #ifndef CLASSES_INC #define CLASSES_INC #include <iostream> class static_class { public: static_class(int array[]) { std::cout<<sizeof(array)/sizeof(int)<<"\n"; } }; class my_class{ public: static static_class s; static int array[4]; }; #endif In classes.cpp, there is this code: #include "classes.h" int my_class::array[4]={1, 2, 3, 4}; static_class my_class::s = static_class(my_class::array); In main.cpp, there is only simple #include "classes.h" int main () { return 0; } Now, the desired output (from the constructor of static_class) is 4. But what I get is 1. Why is that?

• Dynamic access of classes of a given namespace

  - by user322383

  Hi! I'm writing an interface that will be implemented by a lot of classes, and I'm writing a class that will hold a collection of instances of these implementations. Every class will have a default constructor. So, is there a simple way (e.g. using some kind of reflection) to put an instance of each of these implementing classes to the collection? Besides doing it manually, which is simple, yes, but a lot of work and error prone (what if I missed an implementation while writing the method? What if a new implementation came and I forgot to update the given method?). So, what I would like is to be able to iterate through all classes of a given namespace or maybe through the list of all available classes. My method then would simply check, through reflection, if the given class implements the given interface, and if it does, puts it into the collection. Thank you.

• Hibernate: Querying objects by attributes of inherited classes

  - by MichaelD

  Hi all, I ran into a problem with Hibernate concerning queries on classes which use inheritance. Basically I've the following class hierarchy: @Entity @Table( name = "recording" ) class Recording { ClassA attributeSet; ... } @Entity @Inheritance( strategy = InheritanceType.JOINED ) @Table( name = "classA" ) public class ClassA { String Id; ... } @Entity @Table( name = "ClassB1" ) @PrimaryKeyJoinColumn( name = "Id" ) public class ClassB1 extends ClassA { private Double P1300; private Double P2000; } @Entity @Table( name = "ClassB2" ) @PrimaryKeyJoinColumn( name = "Id" ) public class ClassB2 extends ClassA { private Double P1300; private Double P3000; } The hierarchy is already given like this and I cannot change it easily. As you can see ClassB1 and ClassB2 inherit from ClassA. Both classes contain a set of attributes which sometimes even have the same names (but I can't move them to ClassA since there are possible more sub-classes which do not use them). The Recording class references one instance of one of this classes. Now my question: What I want to do is selecting all Recording objects in my database which refer to an instance of either ClassB1 or ClassB2 with e.g. the field P1300 == 15.5 (so this could be ClassB1 or ClassB2 instances since the P1300 attribute is declared in both classes). What I tried is something like this: Criteria criteria = session.createCriteria(Recording.class); criteria.add( Restrictions.eq( "attributeSet.P1300", new Double(15.5) ) ); criteria.list(); But since P1300 is not an attribute of ClassA hibernate throws an exception telling me: could not resolve property: P1300 of: ClassA How can I tell hibernate that it should search in all subclasses to find the attribute I want to filter? Thanks MichaelD

• Modularity Java: top level vs. nested classes

  - by an00b

  The Java tutorials that I read, like to use nested classes to demonstrate a concept, a feature or use. This led me to initially implement a sample project I created just like that: Lots of nested classes in the main activity class. It works, but now I got a monstrous monolithic .java file. I find it somewhat inconvenient and I now intend to break to multiple .java files/classes. It occurred to me, however, that sometimes there may be reasons not to take classes out of their enclosing class. If so, what are good reasons to keep a module large, considering modularity and ease of maintenance?

• Do Hibernate table classes need to be Serializable?

  - by Scott Leis

  I have inherited a Websphere Portal project that uses Hibernate 3.0 to connect to a SQL Server database. There are about 130 Hibernate table classes in this project. They all implement Serializable. None of them declare a serialVersionUID field, so the Eclipse IDE shows a warning for all of these classes. Is there any actual need for these classes to implement Serializable? If so, is there any tool to add a generated serialVersionUID field to a large number of classes at once (just to make the warnings go away) ?

• Wireless router setup for 1-1 NAT

  - by Carlos

  What I have: A linksys router WAG160N with firmware version 2 A "pool" of 5 external static IP's provided by my ISP 213.xx.xxx.n All the required configuration values for the static IPs such as (Subnet Mask, Gateway and static DNS 1, 2, 3) Current WAN Configuration: Encapsulation: RFC 2364 PPPoA Multiplexing: VC QoS type: UBR DSL modulation: MultiMode What's connected to the network: 1 x Server (That I want to make available to the outside) 5 x Desktops with static internal IP's, such as 192.168.0.xx 2 x Network printers, also with internal static IP's 2 x Laptops 1 x NAS (Network Attached Storage) also on static IP What I want to do: I would like to make the server available from outside the network, for example from your house. The problem is that Im not really sure how to do this. I have tried following the steps on the instruction manual in Linksys but they do not seem to work, once I set it up as shown bellow, I loose internet and all hell breaks loose. Going into further detail, I would prefer if the network is changed as little as possible, by this I mean that all the computers stay networked within eachother and only the server is accessible from the outside the network. What I need HELP with: I have read around that it is possible to set a 1-1 NAT (I know where it is in the menu but have no clue what it does...) so that I can NAT a single public IP directly to a single private IP (in our case the server). But please, How do I do that? Or maybe an alternative?

• Static files in (Java) App Engine not accessible.

  - by fiXedd

  The example documentation says that you simply need to place your files in war/ (or a subdirectory) and they should be accessible from the host (as long as they aren't JSPs or in WEB-INF). For example, if you place foo.css in war/ then you should be able to access it at http://localhost:8080/foo.css. However, this isn't working for me at all. NONE of my static files are accessible. The docs on appengine-web.xml say that you can also specifically denote certain types as static. I've tried this as well and it makes no difference. Am I missing something obvious? UPDATE: Turns out one of the mappings in my web.xml was a little too aggressive. The following was the culprit: <servlet> <servlet-name>Main</servlet-name> <servlet-class>MainServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>Main</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> It seems that it was grabbing everything that wasn't grabbed be one of the other rules, which I don't understand because there was no * on the end of the url-pattern. It also seems to be directly contradictory to the documentation that says: Note: Static files, files that are served verbatim to users such as images, CSS or JavaScript, are handled separately from paths mentioned in the deployment descriptor. A request for a URL path that matches a path to a file in the WAR that's considered a static file will serve the file, regardless of servlet and filter mappings in the deployment descriptor. You can exclude files from those treated as static files using the appengine-web.xml file. So, how can I have a rule that matches the base of my domain (eg. http://www.example.com/) and still allows the static files to filter through?

• What is the purpose of abstract classes?

  - by SpikETidE

  I am trying to learn OOP in PHP, and I have some confusion about interfaces and abstract classes. They both contain no implementations, only definitions, and should be implemented through their sub-classes. What part of abstract classes clearly distinguishes them from interfaces? Also, due to their apparent similarities, based on what reasons should I decide to use one over the other?

• How to disable sql creation for JPA entity classes

  - by Samuel

  We have some JPA entity classes which are currently under development and wouldn't want them as part of the testing cycle. We tried commenting out the relevant entity classes in META-INF\persistence.xml but the hbm2ddl reverse engineering tool still seems to generate SQL for those entities. How do I tell my code to ignore these classes? Are there any annotations for these or should I have to comment out the @Entity annotation along with my changes in persistence.xml file.

• In Sinatra, how can I serve static index.html files in subdirectories in public folder?

  - by socrateos

  I noticed that Sinatra does not recognize index.html files in public folder's subdirectories and returns an error when url is pointing to a directory without specifiying the file name. For example, if user enters a url like "www.mydomain.com/subdiretory/", Sinatra fails to recognize the existence of an index.html file in that directory. There are hundreds of subdirectories in my public folder so that it is impossible to specify each one of them in code (and the number of subdirectories keeps growing). How can I tell Sinatra to leave my web server (Apache) alone (to server index.html file) if there is an index.html file in a subdirectory of public folder when url is pointing to that directory without the file name?

• designing classes and objects in .net for a restaurant assignment

  - by Dell Boy

  I have received an assignment at School for creating a Restaurant site. I have to use objects and classes (OOP) for my assignment. I have the foundations of the OOP in .net, but what I don't know is how can I design this assignment to be object-oriented. I don't know how to start it. The requirement is like this: The menu has to be saved in a database and retrieved from it. The menu is devided in appetizers, Salades, Main Meal, Pastas, Wines, Beverages, Extras, Do I create classes like this: Base Class: Menu Derived classes: Appetizers, Salades, Main meal, Pastas, wines, etc. If you have a good example about how to create classes from a Menu that will be great. You don't have to rely on the example I gave above. The menu can be anything. I can deside what the menu will contain. thanks a lot. I am waiting for some help. Please

• When did C++ get nested classes?

  - by Parappa

  Somehow I never noticed until today that C++ supports nested classes. This surprised me because when I was learning C++ back in the '90s, I specifically remember nested classes being something that Object Pascal and Java had, but which C++ did not. I asked an old programmer friend about it and he concurred that he recalls C++ not having nested classes. Is my recollection of C++ not having nested classes mistaken, or were they actually added to the standard at some point in the past fifteen years? I tried searching Google for information on this topic and I haven't come up with anything helpful yet. It could also be that I'm thinking of nested functions, which Pascal certainly supports but C does not.

• Callback from static library

  - by MortenHN

  I think this should be simple, but im having a real hard time finding information about this topic. I have made a static library and have no problem getting the basics to work. But im having a hard time figuring out how to make a call back from the static library to the main APP. I would like my static library to only use one header as front, this header should contain functions like: requestImage:(NSString *)path; requestLikstOfSomething:(NSSting *)guid; and so on.. These functions should do the necessary work and start a async NSURLConnection, and call back to the main application when the call have finished. How do you guys do this, what are the best ways to callback from a static library when a async method is finished? should i do this with delegates (is this possible), notifications, key/value observers. I really want to know how you guys have solved this, and what you regard as the best practices. Im going to have 20-25 different calls so i want the static library header file to be as simple as possible preferable only with a list of the 20-25 functions. UPDATE: My question is not how to use delegate pattern, but witch way is the best to do callbacks from static librarys. I would like to use delegates but i dont want to have 20-25 protocol declarations in the public header file. I would prefer to have only one function for each request. Thanks in advance. Best regards Morten

• C# VS 2008 Build Configurations - using different classes for different builds

  - by evan

  I'm writing an application which has two classes that provide basically the same functionality but for different situations. I'd like to have three versions of the software - one where the user can change an ini file to configure the program to use one of the two classes, and then one version that only uses one of the two classes. Right now I have it working via an ini file, but I'd like to be able to build versions that don't include the code for the unneeded class at all. What is the best way to go about this? My current line of thinking is that since both classes derive from a common interface I'll just add a compile time conditional that looks at the active build configuration and decides whether to compile that class. What is the syntax to do that? Thanks in advance for your help and input!
