  • Is it possible to make a subclass of NSObject which support subnodes in IB for iPhone project?

    - by Eonil
    I'm making a custom UI element class for iPhone. It'll cool to edit my class on Interface Builder with hierarchy. Some of my class is management class like UINavigationController, but they're not one of them, subclasses from NSObject. Of course, I can place a NSObject instance on IB, but it cannot have a child node. Is there a way to enable adding child node to subclass of NSObject?

  • where do i put html files in my web-app folder for a lift project with maven?

    - by egervari
    I'm new to Lift framework for scala. For some reason, index.html resides in the web-app directory, and when I start up jetty, http://localhost:8080/ will point to that index.html file just fine. However, if I put a login.html file in the same folder as the index.html, and then go http://localhost:8080/login, Lift does not serve the file. Where do I need to put the files to get them register? I am a little lost because the behaviour only seems to work for index.html and nothing else. This is what happens when I view source in Chrome: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html> <body>The Requested URL /login was not found on this server</body> </html>

  • How to insert multiple check-box values inside database when one or more will be left unchecked?

    - by Sally
    I have a form that contains 5 check boxes. The user may select one or more of these check boxes. The user may select 2 and leave 3 unchecked or select 4 and leave one unchecked and so on, in that case how can I write the php/mysql code that will insert the form data into the database. With just one selection it's easy, I would do: $checkbox_value = $_POST['i_agree']; mysql_query("INSERT INTO terms (user, pass, conditions) VALUES ('$user','$pass','$checkbox_value')"); But how can I write this when there are multiple check box options and only one or more of them will be checked? I want to insert them all in one column called "tags" separated by commas.

  • Where can I find project repositories with continuous testing?

    - by Jenny Smith
    I am interested in studying some test logs from different projects, in order to build and test an application for school. I need to analyze the parts of the code which are tested, the bugs which appeared in those parts and eventually how they were resolved. But for this I need some repositories from different (open source) projects. Can someone please help me with ideas or links or any kind of test logs which might be useful? I really need some resources, so any help is appreciated.

  • LINQ Group By to project into a non-anonymous type?

    - by vikp
    Hi, I have the following LINQ example: var colorDistribution = from product in ctx.Products group product by product.Color into productColors select new { Color = productColors.Key, Count = productColors.Count() }; All this works and makes perfect sense. What I'm trying to achieve is to group by into a strong type instead of anonymous type. For example I have a ProductColour class and I would like to Group into a List<ProductColour> Is this possible? Thank you

  • How to properly reserve identity values for usage in a database?

    - by esac
    We have some code in which we need to maintain our own identity (PK) column in SQL. We have a table in which we bulk insert data, but we add data to related tables before the bulk insert is done, thus we can not use an IDENTITY column and find out the value up front. The current code is selecting the MAX value of the field and incrementing it by 1. Although there is a highly unlikely chance that two instances of our application will be running at the same time, it is still not thread-safe (not to mention that it goes to the database everytime). I am using the ADO.net entity model. How would I go about 'reserving' a range of id's to use, and when that range runs out, grab a new block to use, and guarantee that the same range will not be used.

  • Project. Properties.Settings versus plain old appSettings?

    - by BryanG
    I have an assembly built that uses appSettings in the app.config...pretty straight forward. however, I'm referencing this assembly in a web service, and that web service contains the nAnt build file for this service plus being the entry point for everything. Ideally I'd like to be able to set the assembly's appConfig values from the build file, but is this possible? Or do I have to switch to using the Settings values of the assembly and do something like this in the build: <xmlpoke file="${PublishLocation}\web.config" xpath="//applicationSettings/Namespace.AssemblyClass.Properties.Settings/setting[@name='ExchangeServer']/value" value="${ServerName}" /> You get the idea. Is this possible with just a config? My ideal situation would be to keep the settings more flexible in the appConfig so that when everything is on the server, if frogs rain down, I can update the assembly's config values without rebuilding the solution. Is this even possible (the xpath is wrong, it's just an example of what I'd like to do): <xmlpoke file="${PublishLocation}\web.config" xpath="//appSettings/Namespace/AssemblyClass/add[@key = 'ExchangeServer']/@value" value="${a}" />

  • How can I set up a database (SQL?) for literary annotations?

    - by Jon
    I'm a literature student and I'd like to be able to annotate literary texts (originally stored in HTML or as text files) on a word-by-word or line-by-line basis. I hear databases like mySQL or SQLite would be good ways to do this sort of thing, but I don't really know where to start. I'm comfortable with the linux command-line, and have done some HTML/CSS work in the past, so I feel unintimidated by databases and things...I just don't know what to start doing.

  • Unable to Uninstall Exchange 2010 ("Internet Newsgroups" public folder)

    - by helplessITguy
    I am trying to uninstall Exchange 2010, before installing a new instance of Exchange 2010 SP1 on a different server. (Our production Exchange server is 2003) We have met all of the Mailbox uninstall prereqs except for the following: Error: Uninstall cannot continue. Database 'Public Folder Database 1579722947': The public folder database "Public Folder Database 1579722947" contains folder replicas. Before deleting the public folder database, remove the folders or move the replicas to another public folder database. For detailed instructions about how to remove a public folder database, see http://go.microsoft.com/fwlink/?linkid=81409&clcid=0x409. Recommended Action: We have been able to delete all Public Folders in the 2010 storage group except for the one (previously replicated) folder - "Internet Newsgroups". How can I delete this folder without impacting public folders on the production Exchange 2003 server? We have: verified permissions to the public folder removed replication for the folder on (on the Exch 2010 server) tried PowerShell scripts: RemoveReplicaFromPFRecursive Get-PublicFolder -Server "\" -Recurse -ResultSize:Unlimited | Remove-PublicFolder -Server -Recurse -ErrorAction:SilentlyContinue

  • Get the last N rows in the database in order?

    - by Kristopher
    Let's say I have the following database table: record_id | record_date | record_value -----------+-------------+-------------- 1 | 2010-05-01 | 195.00 2 | 2010-07-01 | 185.00 3 | 2010-09-01 | 175.00 4 | 2010-05-01 | 189.00 5 | 2010-06-01 | 185.00 6 | 2010-07-01 | 180.00 7 | 2010-08-01 | 175.00 8 | 2010-09-01 | 170.00 9 | 2010-10-01 | 165.00 I want to grab the last 5 rows with the data ordered by record_date ASC. This is easy to do with: SELECT * FROM mytable ORDER BY record_date ASC LIMIT 5 OFFSET 4 Which would give me: record_id | record_date | record_value -----------+-------------+-------------- 6 | 2010-07-01 | 180.00 7 | 2010-08-01 | 175.00 3 | 2010-09-01 | 175.00 8 | 2010-09-01 | 170.00 9 | 2010-10-01 | 165.00 But how do I do this when I don't know how many records there are and can't compute the magic number of 4? I've tried this query, but if there are less than 5 records, it results in a negative OFFSET, which is invalid: SELECT * FROM mytable ORDER BY record_date ASC LIMIT 5 OFFSET (SELECT COUNT(*) FROM mytable) - 5; So how do I accomplish this?

  • Can this code cause a memory leak (Arduino)

    - by tbraun89
    I have a arduino project and I created this struct: struct Project { boolean status; String name; struct Project* nextProject; }; In my application I parse some data and create Project objects. To have them in a list there is a pointer to the nextProject in each Project object expect the last. This is the code where I add new projects: void RssParser::addProject(boolean tempProjectStatus, String tempData) { if (!startProject) { startProject = true; firstProject.status = tempProjectStatus; firstProject.name = tempData; firstProject.nextProject = NULL; ptrToLastProject = &firstProject; } else { ptrToLastProject->nextProject = new Project(); ptrToLastProject->nextProject->status = tempProjectStatus; ptrToLastProject->nextProject->name = tempData; ptrToLastProject->nextProject->nextProject = NULL; ptrToLastProject = ptrToLastProject->nextProject; } } firstProject is an private instance variable and defined in the header file like this: Project firstProject; So if there actually no project was added, I use firstProject, to add a new one, if firstProject is set I use the nextProject pointer. Also I have a reset() method that deletes the pointer to the projects: void RssParser::reset() { delete ptrToLastProject; delete firstProject.nextProject; startProject = false; } After each parsing run I call reset() the problem is that the memory used is not released. If I comment out the addProject method there are no issues with my memory. Someone can tell me what could cause the memory leak?

  • How to access properties of Access Database Table using C# ADOX?

    - by Sachin G
    I have created MS Access Database using C# ADOX library. I have created one table with several columns. What I want to achieve is when I insert date in one column, the date format should be YYYY-MM-DD and not MM-DD-YYYY. I know its just display format, but I want to access the property which we set when we open access table in design mode, and for column with date data type, set format as Custom (YYYY-MM-DD). I want this to be set at runtime while creating table only. I wanted to know what should be property name that I should use in order to access and set the format property of column?

  • How To Add Custom ModelValidatorProviders To Web API Project?

    - by Mark S.
    I'm moving some MVC code to Web API and I need to update my custom ModelValidatorProviders. It seems as though my validators can stay much the same only they should inherit the System.Web.Http.Validation namespace. What I can't figure out is how to add the provider to Web API. When using MVC I can just add the following to my global.asax: ModelValidatorProviders.Providers.Add(new CustomModelValidatorProvider()); How do I use the custom provider with Web API?
