  • Portable way to get file size in C/C++

    - by chmike
    I need to determin the byte size of a file. The coding language is C++ and the code should work with Linux, windows and any other operating system. This implies using standard C or C++ functions/classes. This trivial need has apparently no trivial solution.

  • Protected Class In C#

    - by ChloeRadshaw
    This compiles well for me - However other people on a different thread are saying that protected classes cannot be declared in c# at top level Is that the case? using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace ConsoleApplication1 { protected class CsvReader { } }

  • Generate set/get methods for a c++ class

    - by Narek
    Is there any tool that generates set and get methods for a class. Just I create classes very frequently and would like to have a tool which for each class-member wil generate following functions: Member_Type getMemberName() const; void setMemberName(const Member_Type & val);

  • a design to avoid circular reference in this scenario

    - by BDotA
    Here is our dependency tree: BigApp - Child Apps - Libraries ALL of our components are HEAVILY using one of the Libraries as above ( LibA). But it has a ‘few’ public methods that require classes from ‘higher-level’ assemblies and we want to avoid CIRCULAR references. What do you propose as a good design for this?

  • SNMP - So I have a MIB. Now What?

    - by senfo
    I can't seem to get my head wrapped around the purpose of a MIB. I have a collection of ~20 MIB files that were supplied to me by the vendor, but what do I do with them? I also have a few OID's that were supplied by the vendor that don't seem to be valid. When I issue an "snmpget -v1 -c public 192.168.0.123 .1.4.6.3.2.6.2" (assume that's a valid OID), I get an error indicating the variable is unknown. Does this sound like a hardware configuration problem? Do I need to "load" (for lack of better words) the MIB into the device? Unfortunately, the vendor has been completely unresponsive with returning emails to my questions, so any help would be greatly appreciated.

  • How to build a database from an XSD schema and import XML data

    - by FreshCode
    I have a complex XSD schema and hundreds of XML files conforming to the schema. How do I automate the creation of related SQL Server tables to store the XML data? I've considered creating C# classes from the XSD schema using the xsd.exe tool and letting something like Subsonic figure out how to make a shiny database out of it, but not sure if it's the best way to approach it. Has anyone managed to elegantly import XSD files into SQL Server?

  • Is it a good or bad practice to call instance methods from a java constructor?

    - by Steve
    There are several different ways I can initialize complex objects (with injected dependencies and required set-up of injected members), are all seem reasonable, but have various advantages and disadvantages. I'll give a concrete example: final class MyClass { private final Dependency dependency; @Inject public MyClass(Dependency dependency) { this.dependency = dependency; dependency.addHandler(new Handler() { @Override void handle(int foo) { MyClass.this.doSomething(foo); } }); doSomething(0); } private void doSomething(int foo) { dependency.doSomethingElse(foo+1); } } As you can see, the constructor does 3 things, including calling an instance method. I've been told that calling instance methods from a constructor is unsafe because it circumvents the compiler's checks for uninitialized members. I.e. I could have called doSomething(0) before setting this.dependency, which would have compiled but not worked. What is the best way to refactor this? Make doSomething static and pass in the dependency explicitly? In my actual case I have three instance methods and three member fields that all depend on one another, so this seems like a lot of extra boilerplate to make all three of these static. Move the addHandler and doSomething into an @Inject public void init() method. While use with Guice will be transparent, it requires any manual construction to be sure to call init() or else the object won't be fully-functional if someone forgets. Also, this exposes more of the API, both of which seem like bad ideas. Wrap a nested class to keep the dependency to make sure it behaves properly without exposing additional API:class DependencyManager { private final Dependency dependency; public DependecyManager(Dependency dependency) { ... } public doSomething(int foo) { ... } } @Inject public MyClass(Dependency dependency) { DependencyManager manager = new DependencyManager(dependency); manager.doSomething(0); } This pulls instance methods out of all constructors, but generates an extra layer of classes, and when I already had inner and anonymous classes (e.g. that handler) it can become confusing - when I tried this I was told to move the DependencyManager to a separate file, which is also distasteful because it's now multiple files to do a single thing. So what is the preferred way to deal with this sort of situation?

  • php $_SESSION[document_root] too far down the tree

    - by Idealflip
    Hi, I have multiple sub-domains within the document_root. And multiple folders/classes within those sub-domain folders. I need something that will help me with my include_once paths, but $_SESSION[DOCUMENT_ROOT] goes too far down. And if I were to use this, and transfer the website folder later, all my include_once paths will/might break. Hope my question is clear... Any recommendations?

  • Grails problem with nullable contraint in domain class

    - by xain
    Hi, I'm having the following problem with grails' 1.2.1 domain classes: When I set a constraint attr(nullable:true) and attr is int or bool, this condition isn't reflected in the db (postgresql 8.4). However, if attr is a String, the DB is consistent with the situation. Any hints ? Thanks

  • JBoss 4.2.3 Won't Start

    - by Thody
    Hi, I'm trying to start a new installation of JBoss 4.2.3, and it's getting as far as "INFO [Server] Core system initialized", then hanging for several minutes. There is a Java process running, but only at ~35%. Also, looking at the boot.log, there are no entries after ~1s after starting the boot. Any ideas what might be up? Update: After about 10 minutes, I got a handful of garbage collection warnings: GC Warning: Repeated allocation of very large block (appr. size 512000): May lead to memory leak and poor performance.

  • Saving a grails object with a composite id

    - by Jared
    The answer to this may be obvious but how do you save an object, in grails, that has a composite id. I have an object that has a composite id including a long and a date and I am trying to save an instance of the object from the update method of another classes controller, and using (object).save() isn't working. Any tips or suggestions?

  • In .NET Xml Serialization, is it possible to serialize a class with an enum property with different

    - by Lasse V. Karlsen
    I have a class, containing a list property, where the list contains objects that has an enum property. When I serialize this, it looks like this: <?xml version="1.0" encoding="ibm850"?> <test> <events> <test-event type="changing" /> <test-event type="changed" /> </events> </test> Is it possible, through attributes, or similar, to get the Xml to look like this? <?xml version="1.0" encoding="ibm850"?> <test> <events> <changing /> <changed /> </events> </test> Basically, use the property value of the enum as a way to determine the tag-name? Is using a class hierarchy (ie. creating subclasses instead of using the property value) the only way? Edit: After testing, it seems even a class-hierarchy won't actually work. If there is a way to structure the classes to get the output I want, even with sub-classes, that is also an acceptable answer. Here's a sample program that will output the above Xml (remember to hit Ctrl+F5 to run in Visual Studio, otherwise the program window will close immediately): using System; using System.Collections.Generic; using System.Xml.Serialization; namespace ConsoleApplication18 { public enum TestEventTypes { [XmlEnum("changing")] Changing, [XmlEnum("changed")] Changed } [XmlType("test-event")] public class TestEvent { [XmlAttribute("type")] public TestEventTypes Type { get; set; } } [XmlType("test")] public class Test { private List<TestEvent> _Events = new List<TestEvent>(); [XmlArray("events")] public List<TestEvent> Events { get { return _Events; } } } class Program { static void Main(string[] args) { Test test = new Test(); test.Events.Add(new TestEvent { Type = TestEventTypes.Changing }); test.Events.Add(new TestEvent { Type = TestEventTypes.Changed }); XmlSerializer serializer = new XmlSerializer(typeof(Test)); XmlSerializerNamespaces ns = new XmlSerializerNamespaces(); ns.Add("", ""); serializer.Serialize(Console.Out, test, ns); } } }

  • How to validate user with SimpleMembership

    - by Rushino
    I am using SimpleMembership for user login stuff in my web application. I wrote a console that actually access my web application classes to avoid duplicate code. However, since my console application doesn't have anything related to user sessions the Login method doesn't work. But is there a way to validate a user only using the SimpleMembership? In case i have to do it manually.. how can i do it ?

  • .NET Results Class

    - by pm_2
    I have a C# function that does some processing and needs to return figures about what it has processed, success, failure, etc. Can anyone tell me if there are any standard framework classes that will handle this (for example, number of records processed, number successful, failed, etc) ? Alternatively, can anyone say how they usually handle this? Is the best way to create a class, or to use out parameters?

  • When should I implement IDisposeable?

    - by Bobby
    What is the best practice for when to implement IDisposeable? Is the best rule of thumb to implement it if you have one managed object in the class, or does it depend if the object was created in the class or just passed in? Should I also do it for classes with no managed objects at all?
