  • How do I (or should I?) access the service layer from a SiteMesh template (views/layouts/main.gsp) in Grails?

    - by knorv
    I need to create a toplist in the page footer on a site that I'm building. The footer is created in the default SiteMesh layout template (views/layouts/main.gsp). In order to create the toplist access to the database is needed, so I've encapsulated all logic needed for the toplist creation in a service class (services/FooService). Please note that while services are usually accessed from the controller layer, in this case the default layout template (views/layouts/main.gsp) is not generated from a controller. Can the layout view (views/layouts/main.gsp) access a service class? How? Is this the correct design decision? If not, what is a better encapsulation and how do I interact with said encapsulation from the layout view (views/layouts/main.gsp)?

  • Parser Error Debugging VS2008

    - by maatthias
    When I create new VS2008 asp.net application it builds fine. But when I start debugging I get below error in browser. I've rebuilt the app. The Inherits clause of the markup page matches the class in the code-behind C#. Any clues? Server Error in '/' Application. Parser Error Description: An error occurred during the parsing of a resource required to service this request.

  • iPhone App takes up too much memory

    - by Stephen Furlani
    Ok, so here's my problem. My iPhone app is 1.2MB on disk. Granted I have a bunch of Images for the GUI buttons and backgrounds, etc. In-memory, my app takes up a whopping 15MB! That means if I then take a picture with the camera, 8MB default, it gives a memory warning (several) even before the picker calls its delegate! How can I tell what is grabbing so much memory, and how to remove it? I've removed all of my debugging symbols and added [-Os], but it still takes up a huge amount of memory! Also, (how) can I change the default resolution of the camera?

  • CouchDB Lucene How to URL Encode Query containing Minus (-)

    - by Peter
    I'd like to query text containing a minus (-) Sign, e.g. foo-bar with a couchdb lucene fulltext query. Following lucene rules I'd have to escape the minus, resulting in foo\-bar Last I'd have to urlencode the backslash resulting in foo%5C-bar So the complete url would be: http://127.0.0.1:5984/_fti/local/db/_design/foo/by_subject?q=foo%5C-bar Neither works. The result is always split in two phrases "q":"default:foo default:bar" Leading to documents containing only foo or bar being found also. Thanks for your help!

  • Form authentication works on dev server but not on IIS

    - by Ilknur
    Hi, We have a similar problem. We have a web application running under default appdomain. It was working fine until a week before...Suddenly it has encountered a problem. Below message is taken from event logs. Event code: 4005 Event message: Forms authentication failed for the request. Reason: The ticket supplied has expired. Application uses FormsAuthentication and gets the roles from aspnetdb.. After the error, when user logins to the page, it does not redirects to the default.aspx. Again login.aspx comes up. On the other hand application works fine on development server(localhost), but not on www(IIS 6.0). Does any one has an idea? Thanks, Ilknur

  • TFS Automated Builds to Code Packages

    - by Adam Jenkin
    I would like to hear the best practices or know how people perform the following task in TFS 2008. I am intending on using TFS for building and storing web applications projects. Sometimes these projects can contain 100's of files (*.cs, *.acsx etc) During the lifetime of the website, a small bug will get raised resulting in say a stylesheet change, and a change to default.aspx.cs for example. On checking in these changes to TFS, and automated build would be triggered (great!), however for deploying the changes to the target production machine, I only need to deploy for example: style.css default.asx MyWebApplications.dll So my question is, can MSBuild be customized to generate a "code pack" of only the files which require deploying to the production server based on the changeset which cause the re-build?

  • Hierarchy of modules in guice

    - by Niko
    Hi, I'd like to run a unit test where a constant is slightly different than in the standard version. That is, in my default module, the following is bindConstant().annotatedWith(Names.named("number of players")).to(4); but in testing, I'd like to try this line instead: bindConstant().annotatedWith(Names.named("number of players")).to(2); Id like to achieve that without copying all of the rest of the module. What I really want is a "default" module that is "below" a more specialized module, such that in case of conflict, the specialized module wins (instead of throwing an exception, which is what guice does). In essence, my question is: how does anybody arrange for more than one module without lots of code duplication?

  • C++: How do I correctly register and unregister file type associations for our application (programa

    - by Mordachai
    Time was when you set file associations in: HEY_CLASSES_ROOT\<.ext However, that seems to be possible, but an incomplete solution anymore. There are additional associations throughout the registry. For example: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\KindMap HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\Extensions And all of the above, but by HKEY_USERS\ And Microsoft added their Set Default Associations control panel applet, which controls... what? I'm looking for a white paper, or discussions on: "How is a modern, Windows XP-Windows 7 compatible application written in C/C++ supposed to register and manipulate its file associations without interfering with Explorer, User-Settings, or the Default Associations cpl"

  • MPMediaickerController memory leak identified by Leaks instrument

    - by Joe
    This is code from Apple's Addmusic example. MPMediaPickerController *picker = [[MPMediaPickerController alloc] initWithMediaTypes: MPMediaTypeMusic]; picker.delegate = self; picker.allowsPickingMultipleItems = YES; picker.prompt = NSLocalizedString (@"Add songs to play", "Prompt in media item picker"); // The media item picker uses the default UI style, so it needs a default-style // status bar to match it visually [[UIApplication sharedApplication] setStatusBarStyle: UIStatusBarStyleDefault animated: YES]; [self presentModalViewController: picker animated: YES]; [picker release]; I'm using this code in my app and the Leaks instrument highlights a leak on the line: [self presentModalViewController: picker animated: YES]; I think that this is because this line retains a reference to picker which cannot be subsequently released. Is there any way around this or is Leaks incorrectly identifying a leak?

  • Can I use a local::lib if local::lib isn't installed globally and without eval-ing it in shell?

    - by xenoterracide
    I have a problem, I want to use local::lib; in a script. But because I need to use this script many places, I don't want to try adding the eval to bashrc, every time I install this script to a server. and I can't get local::lib installed globally (in the default @INC) on the servers. Is there any way I can use local::lib from within the script so that it knows where the module local::lib is without the eval that local::lib recommends and without installing it into a directory in the default @INC on the server?

  • Using new to allocate an array of class elements with an overloaded constructor in C++.

    - by GordoN
    As an example say I have a class foo that does not have a default constructor but one that looks like this foo:foo(int _varA,int _varB) { m_VarA = _varA; m_VarB = _varB; } How would I allocate an array of these. I seem to remember trying somthing like this unsuccessfully. foo* MyArray = new foo[100](25,14). I don't think this will work either. foo* MyArray = new foo[100](25,14) Can this be done? I typically do this by writing the default constructor using some preset values for _varA and _varB. Then adding a function to reset _varA and _varB for each element but that will not work for this case. Thanks for the help.

  • .NET DefaultValue attribute

    - by Aaron
    I've heard people say a few different things about the DefaultValue attribute including: "It sets the value of the property before anything else uses it." "It doesn't work for autoproperties." "It's only for decoration. You must manually set actual default values." Which (if any) is right? Does DefaultValue actually set default values? Are there cases where it doesn't work? Is it best just not to use it?

  • Unique constraint with nullable column

    - by Álvaro G. Vicario
    I have a table that holds nested categories. I want to avoid duplicate names on same-level items (i.e., categories with same parent). I've come with this: CREATE TABLE `category` ( `category_id` int(10) unsigned NOT NULL AUTO_INCREMENT, `category_name` varchar(100) NOT NULL, `parent_id` int(10) unsigned DEFAULT NULL, PRIMARY KEY (`category_id`), UNIQUE KEY `category_name_UNIQUE` (`category_name`,`parent_id`), KEY `fk_category_category1` (`parent_id`,`category_id`), CONSTRAINT `fk_category_category1` FOREIGN KEY (`parent_id`) REFERENCES `category` (`category_id`) ON DELETE SET NULL ON UPDATE CASCADE ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_spanish_ci Unluckily, category_name_UNIQUE does not enforce my rule for root level categories (those where parent_id is NULL). Is there a reasonable workaround?

  • Is there a way to ignore Cache errors in Django?

    - by Josh Smeaton
    I've just set our development Django site to use redis for a cache backend and it was all working fine. I brought down redis to see what would happen, and sure enough Django 404's due to cache backend behaviour. Either the Connection was refused, or various other errors. Is there any way to instruct Django to ignore Cache errors, and continue processing the normal way? It seems weird that caching is a performance optimization, but can bring down an entire site if it fails. I tried to write a wrapper around the backend like so: class CacheClass(redis_backend.CacheClass): """ Wraps the desired Cache, and falls back to global_settings default on init failure """ def __init__(self, server, params): try: super(CacheClass, self).__init__(server, params) except Exception: from django.core import cache as _ _.cache = _.get_cache('locmem://') But that won't work, since I'm trying to set the cache type in the call that sets the cache type. It's all a very big mess. So, is there any easy way to swallow cache errors? Or to set the default cache backend on failure?

  • Interface with inner implementation - good or bad

    - by dermoritz
    I am working on a project with many someInterface - someInterfaceImpl-pairs. Some days ago I got the idea (probably inspired by reading some objective c code) to include the default implementations as an inner class. Now some colleagues (all with much more java experience than me) saw this idea - feedback was between shocked and surprised ("this is working?"). I googled around a bit but didn't find much evidence of usefulness of this "pattern" (personal i like it): pdf-paper and a faq about code style What do you think - especially in those cases where an "default" implementation is tightly coupled to an interface. Update i just found this: Java Interface-Implementation Pair (see accepted answer)

  • How to set the locale for a process launched by CreateProcess()

    - by VoidPointer
    When launching a process with CreateProcessW(), is it possible to have the process created with a different MBCP locale/codepage then the one that is configured as the system-wide default code page? In the target process, this should have the same effect as calling _setmbcp(). The target process is not a unicode-enabled and uses a plain main(int argc, char **argv) entry point. I would like to be able to select the code page to which unicode arguments passed to CreateProcessW() are converted to be different from the system's default codepage for non-unicode programs.

  • How are managed the sequences by JPA and Hibernate?

    - by romaintaz
    Hi all, I am using Hibernate in my project, and many of my entities use a sequence for their technical keys. For example: @Entity @Table(name = "T_MYENTITY") @SequenceGenerator(name = "S_MYENTITY", sequenceName = "S_MYENTITY") public class MyEntity { @Id @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "S_MYENTITY") @Column(name = "MY_ENTITY_ID") private Long entityId; ... } I have two questions about the ID generated by Hibernate when a new object of this class is persisted: Why SequenceGenerator (from javax.persistence) has a default value of allocationSize set to 50 instead of 1? What are the interests of that? What is the default algorithm used by Hibernate to calculate the generated ID? It seems that Hibernate uses the value returned by the sequence hosted by my Oracle database, but then modify it before assigning it to my entity...

  • What color scheme do you use for programming?

    - by EndangeredMassa
    I get a lot of attention at work because I am the only one who bothered to change the default color settings in Visual Studio. I just modified them myself. I can provide the settings file if anyone cares to import it. Here's an example of how it looks. It reminds me of DOS/BASIC programming before I actually knew how to program. I also find it to be very readable. What color schemes do you use?! EDIT: To clarify, I only edited the text settings. The windows and panels of VS2005 are still the windows default.
