  • How do I supply values to an referenced assembly without calling a method it explicitly?

    - by Rob
    Currently I have a static class that I use as my logging module. I’ve added the class to my visual studio solution. Within the class I’ve specified the name and location of the log file to use. Which lets me do stuff like this – which I like and want. Logger.Information(“Page_Load”,”controls loaded correctly”); I’d like to refactor the code and move the logging functionality into a separately compiled assembly, if I did this I would then need to pass in the log file name and location to save the files too. However I don’t want to have to supply this information every time I call the ‘Logging’ method, this would be bad... Logger.Informtaion(“Page_Load”,”controls loaded correctly”,”logfile.txt”,”c:\temp”); Is there any way I can supply this information without having to specify it within each page or via the method call.

  • C semaphores: sem_wait throwing inexplicable error

    - by tocapa
    I'm working on a problem which we have to use semaphores to solve. I have an array which contains two semaphores, gsem, and given certain conditions call sem_wait(&(gsem[me])), which is supposed to waiting until that particular process is woken up. However, for some reason it gives me the error Bad file descriptor. I looked up sem_wait and the Open Group spec says this is not an error sem_wait can cause. This is making my whole program crazy and I have no idea why this is failing.

  • Using a single PHP script for an entire site

    - by briggins5
    I had an idea today (that millions of others have probably already had) of putting all the sites script into a single file, instead of having multiple, seperate ones. When submitting a form, there would also be a hidden field called something like 'action' which would represent which function in the file would handle it. I know that things like Code Igniter and CakePHP exist which help seperate/organise the code. Is this a good or bad idea in terms of security, speed and maintenance? Do things like this already exist that i am not aware of?

  • mysterious difference between rake test and ruby

    - by standup75
    Here is the mysterious: I have a scope which looks like this (in Image.rb) scope :moderate_all, delegates.where("moderation_flag = #{$moderation_flags[:not_moderated]}") Note that delegates is another scope that I am defining before moderate_all When I leave it like this, I can run my test that checks if an image has been "checked-out" it is not available anymore. I don't put the code of the test, because it does not matter actually. With this code, when I run "rake test" it fails, but if I do "ruby test/unit/image_test.rb" it works! I was thinking I am starting to have a bad day. Then I tried scope :moderate_all, lambda { delegates.where("moderation_flag = #{$moderation_flags[:not_moderated]}") } And "rake test" passes! So my problem is solved, but why?

  • Disposing a Bitmap through its Finalizer

    - by devoured elysium
    I have a complex program in which I have to first create, then use wrappers around bitmaps and send them across a lot of different classes. The problem in the end is deciding which classes should dispose the bitmaps. Most of the time the end classes don't know if they can indeed dispose the bitmap as the same bitmap can be used in several places. Also, I can't just copy the bitmaps because this is a kind of resource intensive algorithm and doing it would be dead slow. I looked up on reflector for Image/Bitmap's implementations and they seem to use the Dispose Pattern. So, even if I don't call Dispose(), the CLR will eventually call it some other time. Is it too bad if I just let the bitmaps be as they are, and let the finalizer take care of them?

  • Ruby on Rails: Is there a way to tell what fields failed validation in ActiveRecord?

    - by randombits
    I'm attempting to create an XML builder file that tells a user to know exactly what fields failed validation in the output. I also want to display their input back to them, so that requires me figuring out which fields failed validation. Meaning if someone fails on creating a new user resource, I want to display XML that's meaningful (Besides a meaningful HTTP status number) such as: <errors> <user> <email>bad@email: Invalid email format</email> </user> <errors> The above is tough to do in an XML builder file without knowing what field failed. And if I just iterate over error messages, I won't know how to prob my @user object to get the value that the user supplied.

  • How do you keep Cocoa controllers from getting too big?

    - by zoul
    Hello! Do you have some tricks or techniques to break Cocoa controller classes into smaller chunks? I find that whatever I do the controllers end up being one of the more complicated classes in my design. The basic stuff is simple, but once I have several pop-overs or action sheets running, things get uncomfortably complex. It's not that bad, but still I would like to refactor the code into several standalone chunks. I thought about categories, but the code is not that independent (a lot of times it needs to tap into viewWillAppear, for example) and I find that I spend a long time fighting the compiler. I also thought about adding functionality in layers using inheritance, but that feels like a hack.

  • How to trigger an event in input text after I stop typing/writting?

    - by user1386320
    I want to trigger event just right after I stop typing (not while typing) characters in my input textbox. I've tried with: $('input#username').keypress(function() { var _this = $(this); // copy of this object for further usage setTimeout(function() { $.post('/ajax/fetch', { type: 'username', value: _this.val() }, function(data) { if(!data.success) { // continue working } else { // throw an error } }, 'json'); }, 3000); }); But this example produces a timeout for every typed character and I get about 20 AJAX requests if I type-in 20 characters. On this fiddle I demonstrate the same problem with a simple alert instead of an AJAX. Is there a solution for this or I'm just using a bad approach for this?

  • django - change content inside an iframe

    - by fabriciols
    Hello guys, I have a site running in django and want to make it available on third party sites. In these sites they make my content available through an tag. When my site is requested from within that iframe I would like to modify the content (remove header, filter data, etc.). What would be the best way to do this? Is there any way of knowing that the request is being made from an iframe? Multiples sites will request the same url, can I change the content, based on the requesting site? Thanks! PS: Sorry for my bad english :/

  • Determine what account IIS 7 is using to access folders (and other resources)

    - by Andrew
    Often, out of sheer desperation I will end up enabling "Everyone" access on a folder that a web app is accessing (perhaps for file creation, reading, etc) because I can't figure which user account to enable access on. Obviously, this is a very bad thing to do. Is there a way to determine what account IIS is using at that exact moment to access folders (and perhaps other resources like SQL Server, etc)? Are there logs I can look at that will tell me? Or perhaps some other way? I usually use Windows Auth without impersonation. Not sure if that information is relevant.

  • Any valid use of goto in PHP?

    - by nikic
    I know, there are other questions about the goto statement introduced in PHP 5.3. But I couldn't find any decent answer in there, all were of the type "last resort", "xkcd", "evil", "bad", "EVIL!!!". But no valid example. Only statements that there aren't any uses. Or statements that there are some rare use cases (again, without examples). So, the question is: "Which are the valid uses of goto in PHP". Answers for "Is goto evil" are not welcome and will get downvoted. Thanks :) Or does somebody have a link to an RFC where the decision is explained - I couldn't find one.

  • Running Firefox in the Windows service mode

    - by Leonid
    I'm writing a server running as a Windows service that by request invokes Firefox to generate a pdf snapshot of a webpage. I know it is a bad idea to run a GUI program in service mode, but the server nature of my program restricts from running it in the user mode. Running a user-level 'proxy' also is not an option, since there might be no interactive user logged-in on the machine with the server running. In my experiments Firefox successfully produced pdf when the service was running under a user account that was already logged-in. Obviously it didn't work in other cases: for Local System and user accounts that weren't logged-in. Under LocalSystem with 'Allow service to interact with desktop' option enabled I could see the Firefox started that reports that it's unable to find a printer. Since it wouldn't be practical to require an opened user session for the pdf server to run, is there any workaround for this except running the whole thing from a virtual machine?

  • How to know when the user touches the OK button of the last StoreKit alert "Thank you. Your purchase

    - by Walchy
    I have integrated "In App Purchase" in a game to let the user unlock more levels. Everything works fine, but I have a little problem with the last alert "Thank You. Your purchase was successful. [OK]". My program gets informed that the transaction was successfully completed before this last alert pops up and so my game starts running again - then the alert comes up, annoying the user. I would like to wait with my game running until the user touches the "OK" button, but since it is an alert from StoreKit I have no idea when this happens or how I could catch it. I don't want to create another dialog (this time my own, therefor under my control) below the alert, just asking for touching "OK" again - would be a bad user experience. Anybody have any ideas?

  • How can unit testing make parameter validation redundant?

    - by Johann Gerell
    We have a convention to validate all parameters of constructors and public functions/methods. For mandatory parameters of reference type, we mainly check for non-null and that's the chief validation in constructors, where we set up mandatory dependencies of the type. The number one reason why we do this is to catch that error early and not get a null reference exception a few hours down the line without knowing where or when the faulty parameter was introduced. As we start transitioning to more and more TDD, some team members feel the validation is redundant. Uncle Bob, who is a vocal advocate of TDD, strongly advices against doing parameter validation. His main argument seems to be "I have a suite of unit tests that makes sure everything works". But I can for the life of it just not see in what way unit tests can prevent our developers from calling these methods with bad parameters in production code. Please, unit testers out there, if you could explain this to me in a rational way with concrete examples, I'd be more than happy to seize this parameter validation!

  • Should I denormalize a has_many has_many?

    - by Cameron
    I have this: class User < ActiveRecord::Base has_many :serials has_many :sites, :through => :series end class Serial < ActiveRecord::Base belongs_to :user belongs_to :site has_many :episodes end class Site < ActiveRecord::Base has_many :serials has_many :users, :through => :serials end class Episode < ActiveRecord::Base belongs_to :serial end I would like to do some operations on User.serials.episodes but I know this would mean all sorts of clever tricks. I could in theory just put all the episode data into serial (denormalize) and then group_by Site when needed. If I have a lot of episodes that I need to query on would this be a bad idea? thanks

  • how to raise warning if return value is disregarded - gcc or static code check?

    - by Drakosha
    I'd like to see all the places in my code (C++) which disregard return value of a function. How can I do it - with gcc or static code analysis tool? Bad code example: int f(int z) { return z + (z*2) + z/3 + z*z + 23; } int main() { int i = 7; f(i); ///// <<----- here I disregard the return value return 1; } Update: it should work even if the function and its use are in different files free static check tool

  • What are the advantages of combination WPF + XNA?

    - by MartyIX
    Hi, I'm porting my application from Winforms+XNA to WPF (+ XNA?) and I would like to know if the combination WPF + XNA makes sense or not. If it brings some advantages or if it is rather a bad choice. A few points about my game: It's a desk game with simple 2D animations (movement) Main window contains panels like available games/players etc. + console. I would like to add some fancy scenes to my program (at end of game, ...) http://www.codeproject.com/KB/WPF/XnaInWPF.aspx is the code I would like my program base on. So the appearance is quite similar to a chess program. Thank you for suggestions!

  • Inheriting from List<T> in .NET (vb or C#)

    - by Tony
    I have been delved in C++ world for a while, but now I'm in .NET world again, VB and C# and I wondered if you have a class that represents a collection of something, and you want the ability to use this in a foreach loop, etc... is it better to implement IEnumerable and IEnumerator yourself or should you inherit from the List<T> where T is the object type in it's singular form? I know in C++ for example, inheriting from a container is considered a bad idea. But what about .NET.

  • Does Core Data automatically validate new values when they are set?

    - by mystify
    In this question, someone asked how to write a validation method for Core Data. I did that, and it looks cool. But one thing doesn't happen: The validation. I can easily set any "bad" value and this method doesn't get called automatically. What's the concept behind this? Must I always first call the validation method before setting any value? So would I write setter methods which call the appropriate validation method first? And if yes, what's the point of following a strict convention in how to write the validation method signature? I guess there's also some automatic way of validation, then. How to activate this?

  • Use from value from backing bean in javascript

    - by AlfonsSocken
    What I want is to use a boolean value from applicationContext.xml (Jboss configuration file) in my javascript. Currently I use Spring to inject a value configured in applicationContext.xml into my backingbean. Then I put an output text in my jsp like this <h:outputText id="idValue" styleClass="foo" value="" rendered="#{bean.isRendered}"/> In my JavaScript I try following jQuery(function(){ bRedirect = jQuery("#foo").value != undefined; ... All this looks so terrible to me, even though it works fine. There must be a smarter way than doing what I do. Note that I am running JSF1.2 and therefore must use jQuery instead of $ and also select by unique class (foo) and not by id, which may be bad practice as well. Thank you in advance. alfons

  • For external links on my webpage, should I use a redirector page or just link direct to the external

    - by AaronM
    Hello, just wondering if I should be using a 'redirector' type page or link directly to the external pages on my site http://www.onedaysalefinder.co.nz/ - currently I use a redirector page to track what links are being clicked on (which simply takes an ID, looks up the URL in the database, and then does a Response.Redirect(URL); From a SEO point of view, is this a good idea/bad idea? I understand it can add a few milliseconds extra to the external page load time whilst it looks up the actual URL, but am not too concerned about this. I also get the benefit of tracking the clicks accurately, but are the pros/cons of using a redirector vs the actual link? Am I worrying about something I don't need to? Thanks
