  • How do I register multiple paths for a HttpHandler in IIS7?

    - by Daniel T.
    I have a HttpHandler that resizes images based on the querystring, so requesting something like: http://server/image.jpg?width=320&height=240 will give you a resized image that's 320x240. In the IIS Manager, under Handler Mappings, I mapped my handler's path as *.jpg,*.gif,*.bmp,*.png. However, this doesn't activate the handler. If I change it to just *.jpg, then it works. My question is, do I have to create 4 separate mapping entries, one for each image type, or is there some way to combine multiple extensions in one path?

  • ValidateInputAttribute bug in VS 2010 RC / ASP.NET MVC 2.0?

    - by Ben
    Am I doing something wrong here? I have a text area on a view and am posting back the html contents. In VS 2008 and MVC 1.0 the following code successfully prevents input validation: [HttpPost] [ValidateInput(false)] public ActionResult Index(int? id) { return View(); } If I execute this code in VS 2010 / MVC 2.0 I always get this error: A potentially dangerous Request.Form value was detected from the client (body=""). Any ideas?

  • Multiple remote_form_for on the same page causes duplicate ids

    - by Ben Scheirman
    I've got a rails app that displays a list of items called modules. I'm iterating over these, rendering a partial for each one that includes a remote_form_for call. This all works, but fails HTML validation because my form text fields all have the same id. Is there a :prefix option on the form (or something else) I can use to get around this? Update: (some code) //_module_form.html.erb <% remote_form_for app_module do |f| %> <%= f.label :name %> <%= f.text_field :name %> <%= submit_tag 'Save' %> <%end %> //parent page <% @thing.modules.each do |app_module| %> <%= render :partial => "module_form", :locals => { :app_module => app_module } %> <% end %> So if I have more than 1 item in the collection, I render the identical form on the same page, and the form id and textbox id are duplicated. I can customize the form id pretty easily, but what about the text_box, since the controller is looking for specific named controls?

  • JSF - Session Bean restart on logout and login

    - by Ben
    Hi, I have a web application with a backing bean which has the context of the current logged in user. It is implemented on JSF. When the user logs out he is forwarded to a login screen (in another JSP page). I would like the current session to be erased when that happens and a new one to be created the next time the user logs in and enters the application. My question is - how do you delete a session? (I guess the new session will be created automatically the next time the user enters the link) This is kinda newb i guess, but I couldn't find a solution for this. Thanks for the Help!

  • using a 64-bit compiler in microsoft visual c++

    - by Ben
    this question is essentially identical to an earlier question i had that didn't receive any answers. hopefully someone can help me out this time. i am trying to compile a vc++ project as 64 bit using visual c++ express 2010. i know that the 64 bit compiler does not come with the default installation of vc++ express so i installed windows sdk for windows 7 as specified here (http://msdn.microsoft.com/en-us/library/9yb4317s.aspx) which includes the 64 bit compiler as i understand. however, there is still no 64 bit option in the configuration manager for vc++. after some searching i found and completed this tutorial (http://jenshuebel.wordpress.com/2009/02/12/visual-c-2008-express-edition-and-64-bit-targets/) as well as the various links at the bottom of this page. despite all my efforts, i still cannot get the 64 bit compiler to show in vc++ (i.e. the 64 bit compiler won't show under "active solutions platform" in the configuration manager). if anyone has any experience/tips with getting this to work i would really appreciate it. fyi - i am running windows 7(x64).

  • Haskell - function (that returns a list) on each element in a list

    - by Ben
    The assignment is to create a multiples function and I essentially want todo the following code: map (\t -> scanl (\x y -> x+y) t (repeat t)) listofnumbers The problem is that the scanl function returns a list of results rather than the one which the map function requires. So is there a function that will allow the return of lists?

  • Managing important runtime business logic with regard to a codebase

    - by Daniel Beardsley
    I'm working on a project which will end up have a lot of application information stored in the form of records in a database. In this case, it's the configuration of data views: which grid columns to show/hide default filters to apply to each grid view column titles sorting subtotaling ... This information is a big part of the value of the application and is essential to it's function. The data will be altered by admins a fair amount, so it's not static and it wouldn't be appropriate to have to deploy a new version of the app every time the data changes. The question is, Where should this data be stored? It will definitely live in the database because that's how it's accessed, but I feel like it needs to also be kept with the version controlled codebase because it's an integral part of functioning of the application. Has anyone dealt with an issue like this before? What did you end up doing?

  • How to deserialize implementation classes in OSGi

    - by Daniel Schneller
    In an eRCP OSGi based application the user can push a button and go to a lock screen similar to that of Windows or Mac OS X. When this happens, the current state of the application is serialized to a file and control is handed over to the lock screen. In this mobile application memory is very tight, so we need to get rid of the original view/controller when the lock screen comes up. This works fine and we end up with a binary serialized file. Once the user logs back in, the file is read in again and the original state of the application restored. This works fine as well, except when the controller that was serialized contained a reference to an object which comes from a different bundle. In my concrete case the original controller (from bundle A) can call a web service and gets a result back. Nothing fancy, just some Strings and Numbers in a simple value holder class. However the controller only sees this as a Result interface; the actual runtime object (ResultImpl) is defined and created in a different bundle (bundle B, the webservice client implementation) and returned via a service call. When the deserialization now tries to thaw the controller from the file, it throws a ClassNotFound exception, complaining about not being able to deserialize the result object, because deserialization is called from bundle A, which cannot see the ResultImpl class from bundle B. Any ideas on how to work around that? The only thing I could come up with is to clone all the individual values into another object, defined in the controller's bundle, but this seems like quite a hassle.

  • How can I make jQuery select an element in the style of CSS?

    - by ben
    <div id="id" class="div-style"><img id="1" class="img-style"></div> I would like to use the id attribute as a way for jQuery to select the element, and the class attribute for CSS to style it. My guess for jQuery selector ran thusly: $("#id .div-class") and $("#id .img-class") This returns the error "Selector expected"

  • What's the VB.NET equivalent of this C# code for wiring up and declaring an event?

    - by Ben McCormack
    I'm working on a tutorial to build a media player in Silverlight and am trying to wire up an EventHandler to the timer.Tick event of a DispatchTimer object so that the time of the video is synced with a Slider object. The sample code is in C# and I can't for the life of me figure out the proper syntax in VB.NET with RaiseEvent and/or Handles to wire up the event. Below is the relevant C# code. I'll include comments on where I'm getting stuck. private DispatchTimer timer; public Page() { //... timer = new DispatchTimer(); timer.Interval = TimeSpan.FromMilliseconds(50); timer.Tick += new EventHandler(timer_Tick); // <== I get stuck here b/c // I can't do "timer.Tick += ..." in VB.NET } void timer_Tick(object sender, EventArgs e) { if (VideoElement.NaturalDuration.TimeSpan.TotalSeconds > 0) { sliderScrubber.Value = VideoElement.Position.TotalSeconds / VideoElement.NaturalDuration.TimeSpan.TotalSeconds; } }

  • How to access global variable in a view in Ruby on Rails?

    - by ben
    I have a User model. I have a Session controller, in which I have a global user variable that is assigned as follows: $user = User.authenticate(params[:session][:email], params[:session][:password]) (I've made user global just to try to solve this problem, so if there's a better way please let me know!) I need to use the email of the logged in user as a parameter to send to Flex part of my website. At the moment I'm creating the link as follows: <%= link_to "secondpage", secondpage_path(:email => @session.$user.email) But I'm getting the following error: compile error /Users/benhartney/rails_projects/talk/app/views/layouts/_header.html.erb:12: syntax error, unexpected tGVAR ..._path(:email = @session.$user.email) ).to_s); @output_buffe... There's also a little arrow pointing at $user If I remove the $ from $user, I get this error: undefined method `user' for nil:NilClass If I remove the (:email => @session.user.email) part, everything works fine, so I think all of the code except for this is ok. Can anyone tell me what I'm doing wrong? Thanks for reading!

  • Facebook offline access step-by-step

    - by Ben
    After searchinge litteraly 1 day on fb and google for an up-to-date and working way to do something seemingly simple: I am looking for a step-by-step explanation to get offline_access for a user for a facebook app and then using this (session key) to retrieve offline & not within a browser friends & profile data. Preferrably doing this in the Fb Java API. Thanks. And yes I did check the facebook wiki. Update: Anyone? this: http://www.facebook.com/authorize.php?api_key=<api-key>&v=1.0&ext_perm=offline_access gives me offline_Access, however how to retrieve the session_key? Why can't facebook just do simple documentation, I mean there are like 600 people working there? The seemingly same question: http://stackoverflow.com/questions/617043/getting-offlineaccess-to-work-with-facebook Does not answer how to retrieve the session key Edit: I am still stuck with that. I guess nobody really tried such a batch access out yet...

  • fade in all divs of a page. once the content of the divs is loaded

    - by daniel
    I want all the divs on my page to fade in after the content is loaded. The code below loads in all imgs in the #div container. Which is great. but it does not load in images that are used as div background images loaded through the css file. So i think the most effective way is to create a piece of code that fades in all the divs on the page after the content ie: images and text has loaded. Is there A way to do this. Cheers. $(document).ready(function() { $('#container img').fadeIn(4000); // and tell pending images to do the same, once they've finished loading: $('#container img').load(function () { $(this).fadeIn(4000); }); });

  • Why does first call to java.io.File.createTempFile(String,String,File) take 5 seconds on Citrix?

    - by Ben Roling
    While debugging slow startup of an Eclipse RCP app on a Citrix server, I came to find out that java.io.createTempFile(String,String,File) is taking 5 seconds. It does this only on the first execution and only for certain user accounts. Specifically, I am noticing it Citrix anonymous user accounts. I have not tried many other types of accounts, but this behavior is not exhibited with an administrator account. Also, it does not matter if the user has access to write to the given directory or not. If the user does not have access, the call will take 5 seconds to fail. If they do have access, the call with take 5 seconds to succeed. This is on a Windows 2003 Server. I've tried Sun's 1.6.0_16 and 1.6.0_19 JREs and see the same behavior. I googled a bit expecting this to be some sort of known issue, but didn't find anything. It seems like someone else would have had to have run into this before. The Eclipse Platform uses File.createTempFile() to test various directories to see if they are writeable during initialization and this issue adds 5 seconds to the startup time of our application. I imagine somebody has run into this before and might have some insight. Here is sample code I executed to see that it is indeed this call that is consuming the time. I also tried it with a second call to createTempFile and notice that subsequent calls return nearly instantaneously. public static void main(final String[] args) throws IOException { final File directory = new File(args[0]); final long startTime = System.currentTimeMillis(); File file = null; try { file = File.createTempFile("prefix", "suffix", directory); System.out.println(file.getAbsolutePath()); } finally { System.out.println(System.currentTimeMillis() - startTime); if (file != null) { file.delete(); } } } Sample output of this program is the following: C:\java.exe -jar filetest.jar C:/Temp C:\Temp\prefix8098550723198856667suffix 5093

  • Selecting an item from a very large list

    - by Ben Fulton
    Suppose I have a list of a couple of thousand organizations and a user needs to be able to select one of them. The list is too large to populate in a dropdown at page load, and the user often knows what they want but it's not the first part of the organization name. That is, they know "Collections" but not that the precise name of the organization is "Department of Collections". So the user will need/want to type in some information. It's easy enough to use an autocompleting textbox of some kind, but I don't want to allow the user to type in random text - they have to choose one of the organizations explicitly. What's the best solution?

  • How to install previously-archived apps from xcode organizer to my iphone

    - by Ben Clayton
    Hi all. Xcode keeps an archive of all the versions of my apps that I've submitted to the app store in the 'archived applications' section. I assumed using this I could install an old version of an app to my device, in order to reproduce any problems my client may have had with that particular version. However, when I try to do this I get an error: 'this executable was signed with invalid entitlements, the entitlements specified in your applications code signing entitlements do not match those specified in your provisioning profile' The original app was signed using our App Store distribution certificate, and I use the Organizer interface to re-sign it using our Developer profile. select the archived app select the version I want to test click 'share' select 'iphone developer' next to identity save to disk (saves the ipa file) then copy the ipa to the device using the little + button you see next to 'applications' on the screen you get when you select the connected device. Then I get the error, and the app isn't installed. Is there something obvious I'm doing wrong here? Or is there a different process to re-install an archived app to my device? Thanks,

  • Searching via Tags in SharePoint 2010

    - by Ben
    Is it possible to search on Tags within SharePoint 2010? I know you can refine your search based on Tag (Search for a keyword, then filter by Tags) and you can use the "Tag Cloud", but that doesnt let you search by more then one Tag. How would I for instance, search for some documents that I have tagged as "Technical" and "Internal", and return all items tagged with both of those tags?

  • Where is the appropriate place to define inflector rules in CakePHP 1.3?

    - by Daniel Wright
    In CakePHP 1.2, custom inflector rules could be defined in a file app/config/inflections.php. This file was removed in CakePHP 1.3. Instead, the documentation prescribes using the Inflector::rules function to load custom inflections. There's adequate documentation of how to define the custom inflections themselves, but the documentation gives no context—where to use Inflector::rules. Should any custom inflections be defined in the bootstrap.php script? At the top of applicable corresponding controllers? Somewhere else? See also: Configuration: Inflections in the documentation Inflector::rules definition in the API documentation
