  • Accessing wrapped method attribute in C#

    - by prostynick
    I have following code: public static void ProcessStep(Action action) { //do something here if (Attribute.IsDefined(action.Method, typeof(LogAttribute))) { //do something here [1] } action(); //do something here } For easy use I have some similar methods using method above. For example: public static void ProcessStep(Action<bool> action) { ProcessStep(() => action(true)); //this is only example, don't bother about hardcoded true } But when I use the second method (the one above), even if original action had attribute, code [1] will not be executed. How can I find if method is only wrapper and underlying method contains attribute and how to access this attribute?

  • Dynamically create PHPUnit tests from data-file

    - by DeletedAccount
    I have a data file with input and expected outputs. An example could be: input: output: 2 3 3 5 4 Exception 5 8 ... ... Currently I have a custom solution to read from the data file and perform a test for each {input,output} pair. I would like to convert this into a PHPUnit based solution and I would like to have one test per input using the test name forXassertY. So the first three tests would be called for2assert3(), for3assert5() and for4assertException(). I do not want to convert my existing data to tests if it's possible to create the test methods dynamically and keep the data file as the basis of these tests. I want to convert it to PHPUnit as I want to add some other tests later on and also process and view the output using Hudson. Suggestions?

  • Using jQuery, how to modify text outside of tags?

    - by Jacob
    Given a string of text that is both adjacent to a span and inside of a div, what are some methods to modify just that text, leaving the surrounding HTML intact? For example: <div id="my-div">modify this text<span id="my-span"></span></div> I have tried things like $('#my-div').html(function(i, elem){blah;}); but this seems to cause the span to be deleted and a new span to be added, because some styling is lost. I realize that it would be best to wrap the text string in its own HTML tags before applying client-side code, but that is out of my control.

  • OpenLayers: Get resolution of map in a given projection (4326)

    - by David Pfeffer
    I'm using OpenLayers to display OpenStreetMap maps. (Though, I'd assume this should be general enough to work for any map product...) I'm displaying some very sophisticated vector overlays, and the amount and resolution of the features I'm returning from the server via GeoJSON to overlay has proven too much for many computers. What I'd like to do now instead is to only send data befitting the resolution of the current zoom. This should be relatively easy to do using the getResolution and calculateBounds methods on the Map object. calculateBounds returns a Bounds object that then can be transformed between the map projection and display projection. How do I transform the resolution into my desired projection (4326 in this case)?

  • Can someone explain this java interface to me please?

    - by Karl Patrick
    I realize that the method run must be declared because its declared in the runnable interface. But my question comes when this class runs how is the Thread object allowed if there is no import call to a particular package? how does runnable know anything about Thread or its methods? does the runnable interface extend the thread class? Obviously i dont understand interfaces very well. thanks in advance. class PrimeFinder implements Runnable{ public long target; public long prime; public boolean finished = false; public Thread runner; PrimeFinder(long inTarget){ target = inTarget; if(runner == null){ runner = new Thread(this); runner.start() } } public void run(){ } }

  • PHP - WideImage class cropping

    - by Kolind
    I am trying to crop a large image to make thumbnails. But I can't get WideImage to save the file. I've tried the following: 1st method: $img = WideImage::load('../files/' . $file_name)->crop('center', 'center', 200, 200); $img->saveToFile('../files/thumb/thumb_' . $file_name); 2nd method: $img = WideImage::load('../files/' . $file_name)->crop('center', 'center', 200, 200); $img->copy('../files/thumb/thumb_' . $file_name); But nothing seems to happen, when I am performing any of these methods. I am getting no errors and no thumbnails. Am I doing something wrong here?

  • new image makes http request even though cached?

    - by joshs
    I have a javascript slide show that creates the next slide dynamically and then moves it into view. Since the images are actually sprites, the src is transparent.png and the actual image is mapped via background:url(.. in css. Everytime (well, most of the time) the script creates a new Element, Firefox makes an http request for transparent.png. I have a far-future expires header, and Firefox is respecting all other files' expiries. Is there a way to avoid these unnecessary requests. Even though the server is returning 304 unmodified responses, it would be nice if Firefox would respect the expiries on dynamically created images. I suspect that if I injected a simple string instead of using new Element, this might solve the problem, but I use some methods on Prototypes extended Element object, so I would like to avoid a bunch of html strings in my js file. This is a nit-picky question, but I'm working on front-end optimization now, so I thought I would address it. Thanks.

  • What's an easy way of storing an array of numbers in Javascript that I can add/remove from?

    - by SLC
    In C# I would create a List then I could add and remove numbers very easily. Does identical functionality exist in Javascript, or do I have to write my own methods to search and remove items using a loop? var NumberList = []; NumberList.Add(17); NumberList.Add(25); NumberList.Remove(17); etc. I know I can use .push to add a number, so I guess it's really how to remove an individual number without using a loop that I'm looking for. edit: of course, if there's no other way then I'll use a loop!:)

  • How to detect page redirect with PHP?

    - by blabus
    I'm trying to detect whether an image exists on a remote server. However, I've tried several methods and can't get any of them to work. Right now I'm trying to use this: if (!CheckImageExists("http://img2.netcarshow.com/ABT-Audi_R8_2008_1024x768_wallpaper_01.jpg")) { print_r("DOES NOT EXIST"); } else { print_r("DOES EXIST"); }; function CheckImageExists($imgUrl) { if (fopen($imgUrl, "r")) { return true; } else { return false; }; }; But it returns 'true' whether the image actually exists or not (the above image should, but change it to gibberish and it still will return 'true'). I have a feeling it could be because if the URL does not exist, it redirects to the homepage of the site. But I don't know how to detect that. Thanks for any help!

  • Interacting With Class Objects in Ruby

    - by michaelmichael
    How can I interact with objects I've created based on their given attributes in Ruby? To give some context, I'm parsing a text file that might have several hundred entries like the following: ASIN: B00137RNIQ -------------------------Status Info------------------------- Upload created: 2010-04-09 09:33:45 Upload state: Imported Upload state id: 3 I can parse the above with regular expressions and use the data to create new objects in a "Product" class: class Product attr_reader :asin, :creation_date, :upload_state, :upload_state_id def initialize(asin, creation_date, upload_state, upload_state_id) @asin = asin @creation_date = creation_date @upload_state = upload_state @upload_state_id = upload_state_id end end After parsing, the raw text from above will be stored in an object that look like this: [#<Product:0x00000101006ef8 @asin="B00137RNIQ", @creation_date="2010-04-09 09:33:45 ", @upload_state="Imported ", @upload_state_id="3">] How can I then interact with the newly created class objects? For example, how might I pull all the creation dates for objects with an upload_state_id of 3? I get the feeling I'm going to have to write class methods, but I'm a bit stuck on where to start.

  • How can I configure Xcode to put '{' where I want it in generated files

    - by djhworld
    I know this is a fairly contentious issue amongst programmers, but when developing I like my IDE to position the opening curly bracket underneath the method/interface/control declaration, for illustrative purposes: - This is how Xcode automatically generates skeleton methods with the { at the end: - -(void) isTrue:(BOOL)input { if(input) { return YES; } else { return NO; } } This is how I like to lay out my code (which I believe is called the Allman style): - -(void) isTrue:(BOOL)input { if(input) { return YES; } else { return NO; } } I'm just wondering if there's any configuration switch in Xcode to enable this style of development? It's really annoying when typing out if/else statements as it tends to auto-complete the else clause with the { at the end of the line which just looks silly if you like developing with them underneath. Or am I being unreasonable? Is Objective-C supposed to adhere to a standard defined by Apple?

  • How to filter Delphi 2010 compiler output (hints)?

    - by Paul-Jan
    I'm trying to get rid of some hints(*) the Delphi compiler emits. Browsing through the ToolsAPI I see a IOTAToolsFilter that looks like it might help me accomplish this through it's Notifier, but I'm not sure how to invoke this (through what xxxServices I can access the filter). Can anyone tell me if I´m on the right track here? Thanks! (*) In particular, H2365 about overridden methods not matching the case of the parent. Not so nice when you have about 5 million lines of active code with a slightly different code convention than Embarcadero's. We've been working without hints for months now, and we kinda miss 'm. :-)

  • How to select the most recent set of dated records from a mysql table

    - by Ken
    I am storing the response to various rpc calls in a mysql table with the following fields: Table: rpc_responses timestamp (date) method (varchar) id (varchar) response (mediumtext) PRIMARY KEY(timestamp,method,id) What is the best method of selecting the most recent responses for all existing combinations of method and id? For each date there can only be one response for a given method/id. Not all call combinations are necessarily present for a given date. There are dozens of methods, thousands of ids and at least 356 different dates Sample data: timestamp method id response 2009-01-10 getThud 16 "....." 2009-01-10 getFoo 12 "....." 2009-01-10 getBar 12 "....." 2009-01-11 getFoo 12 "....." 2009-01-11 getBar 16 "....." Desired result: 2009-01-10 getThud 16 "....." 2009-01-10 getBar 12 "....." 2009-01-11 getFoo 12 "....." 2009-01-11 getBar 16 "....." (I don't think this is the same question - it won't give me the most recent response)

  • Embed Icons into WPF Application as Resource

    - by rattrick1
    I am trying to embed an icon into my my WPF application so that I can pull it out for use as an icon in the Window 7 JumpList using the following code: newScene.IconResourcePath = System.Reflection.Assembly.GetEntryAssembly().Location; newScene.IconResourceIndex = 0; I've gotten it to work using the following method: http://dennisdel.com/?p=38 However, it doesn't seem like the best approach and it seems like there should be an easier way to embed an icon resource into my application while still leaving the "Icon and Manifest" option checked in the Application properties for my program. I've tried numerous methods including setting the icon build action as a resource and an embedded resource, but every time I open my .exe in a resource editor, the icon does not appear. Any suggestions?

  • Starting new transaction in Spring bean

    - by Marcus
    We have: @Transactional(propagation = Propagation.REQUIRED) public class MyClass implementes MyInterface { ... MyInterface has a single method: go(). When go() executes we start a new transaction which commits/rollbacks when the method is complete - this is fine. Now let's say in go() we call a private method in MyClass that has @Transactional(propagation = Propagation.REQUIRES_NEW. It seems that Spring "ignores" the REQUIRES_NEW annotation and does not start a new transaction. I believe this is because Spring AOP operates on the interface level (MyInterface) and does not intercept any calls to MyClass methods. Is this correct? Is there any way to start a new transaction within the go() transaction? Is the only way to call another Spring managed bean that has transactions configured as REQUIRES_NEW? Update: Adding that when clients execute go() they do so via a reference to the interface, not the class: @Autowired MyInterface impl; impl.go();

  • C# Fake Enum TypeInitializationException

    - by userk
    I'm trying to create a class that works as a flexible enum. I came with this idea, with 2 additional static methods that allow me to add new members to that list and get only members from that list. public class LikeEnum { private static List<LikeEnum> list = new List<LikeEnum>() { new LikeEnum("One"), new LikeEnum("Two") }; private string value; private LikeEnum(string value) { this.value = value; } } Unfortunately the List list is only initialized as null so this doesn't work... Any ideas or suggestions?

  • Why is sqrt() not a method on Float?

    - by KaptajnKold
    In Ruby everything is an object. That's why I don't understand why we have the Math module. It seems to me that most (all?) of the functions in the Math module should have been methods on the numeric types like Integer, Float and so on. E.g. instead of Math.sqrt(5) it would make more sense to have 5.sqrt The same goes for sin, cos, tan, log10 and so on. Does anyone know why all these functions ended up in the Math module?

  • Linux - Programmatically write to a proc file

    - by Zach
    I have found several examples online where we can create a proc file, assign read and write methods that are called every time the proc file is opened for read or written to. However, I can't seem to find any documentation on how to programatically write to a proc file. Ideally, I would like to add a timestamp with other user details every time the proc file is opened for read or for write. Again, I've found where I can add the read and write functions that are triggered when the proc file is opened, but I can't find documentation on how to actually write to a proc file programatically. This would be different from a regular IO read/write, correct?

  • C++ Word-Number to int

    - by Andrew
    I'm developing a program that makes basic calculations using words instead of numbers. E.g. five + two would output seven. The program becomes more complex, taking input such as two_hundred_one + five_thousand_six (201 + 5006) Through operator overloading methods, I split each number and assign it to it's own array index. two would be [0], hundred is [1], and one is [2]. Then the array recycles for 5006. My problem is, to perform the actual calculation, I need to convert the words stored in the array to actual integers. I have const string arrays such as this as a library of the words: const string units[] = { "", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine" }; const string teens[] = { "ten", "eleven", "twelve", "thirteen", "fourteen", "fifteen", "sixteen", "seventeen", "eighteen", "nineteen" }; const string tens[] = { "", "", "twenty", "thirty", "forty", "fifty", "sixty", "seventy", "eighty", "ninety" }; If my 'token' array has stored in it two hundred one in index 0, 1, and 2, I'm not sure what the best way to convert these to ints would involve.

  • Pass parameters to a user control - asp.net

    - by Cristian Boariu
    Hi, I have this user control: <user:RatingStars runat="server" product="<%= getProductId() %>" category="<%= getCategoryId() %>"></user:RatingStars> You see that i fill the product and category by calling two methods: public string getProductId() { return productId.ToString(); } public string getCategoryId() { return categoryId.ToString(); } I do not understand why, in the user control, when i take the data received (product and category) it gives me "<%= getProductId() %" instead of giving the id received from that method... Any help would be kindly appreciated...

  • Forcing a method to be non-transactional in JPA (Eclipselink)

    - by rhinds
    Hi, I am developing an application using Eclipselink and as part of the app I need to be able to manipulate some of the objects which involves changing data without it being persisted to the database (i merging/changing objects for some batch generation processes). I am reluctant to change the data in the Entity objects, as there is a risk that even though i have not marked the methods as @Transactional, this method could in the future be inadvertantly called from within a transactional method and these changes could be persisted. So my question is, is there anyway to get around this? Such as force a method to always be non-transactional regardless; terminate any transactionality as soon as the method is started; etc. I know there is a .detach() method that can detach the objects from the Entity Manager, however, there are many objects and this seems like a potentially error prone fail-safe on my code.

  • Why is run() not immediately called when start() called on a thread object in java

    - by pi
    Or is it? I have a thread object from: Thread myThread = new Thread(pObject); Where pObject is an object of a class implementing the Runnable interface and then I have the start method called on the thread object like so: myThread.start(); Now, my understanding is that when start() is called, the JVM implicitly (and immediately) calls the run() method which may be overridden (as it is in my case) However, in my case, it appears that the start() method is not called immediately (as desired) but until the other statements/methods are completed from the calling block i.e. if I had a method after the start() call like so: myThread.start(); doSomethingElse(); doSomthingElse() gets executed before the run() method is run at all. Perhaps I am wrong with the initial premise that run() is always called right after the start() is called. Please help! The desired again is making executing run() right after start(). Thanks.

  • Rails: authentication system based on external API

    - by Slevin
    i'm building a Rails application to extend features of an existing online Rails app. The existing Rails app provides an API for authentication. My approach: user X have an account at the existing Rails app. With these login data the user X should authenticate on my Rails app. The existing app offers a gem to connect to the API after login. Whats the best method to store the information about a successful login? Should i use sessions? Or does Rails offer better methods for this?

  • Help me understand Dispose() implementation code from MSDN

    - by Benny
    the following code is from MSDN: Idisposable pattern protected virtual void Dispose(bool disposing) { // If you need thread safety, use a lock around these // operations, as well as in your methods that use the resource. if (!_disposed) { if (disposing) { if (_resource != null) _resource.Dispose(); Console.WriteLine("Object disposed."); } // Indicate that the instance has been disposed. _resource = null; _disposed = true; } } why the following statement: _resource = null; _disposed = true; are not enclosed by if (disposing) statement block? for me i would probably write like this: if (disposing) { if (_resource != null) { _resource.Dispose(); _resource = null; _disposed = true; } Console.WriteLine("Object disposed."); } anything wrong with my version?
