  • Ideas for loading initial data in an iPhone application?

    - by Derek Clarkson
    Hi all, In my app I want to load some initial data to show the user how it works. The app uses a CoreData managed sqllite db. SO far I've thought of 3 options: Write code into a class to programmatically create the data. Create a xml file in the apps resources and load through a NSXmlParser whose delegate creates the entries in the sqllite db. Same as option #2, but use a json file and bring in a 3rd party lib to read it. Are there other options I have not found yet? and given that I'm talking about perhaps 6 records per table when there are 3 tables, which would you choose?

  • Excel workbooks produced by POI don't work when linked

    - by Eric Nicolas
    Here is what I'm doing : Create a workbook in memory (book = new HSSFWorkbook(), ...) Save it to disk (book.write(...)) Open in Excel (ok) Create another workbook in Excel, which links to the first one (=PoiWorkbook?xls!A1) Close Excel Then everytime I open the second workbook again, all the links are #N/A, unless I also open the POI-generated workbook at the same time. I never saw this behaviour with standard workbooks created in Excel. Anyone has seen this and found a workaround ? Thanks.

  • Membership and asp.net MVC

    - by Jemes
    I’m building a site that needs users created with different roles and permissions to access different areas of the site. I using mvc 2 but I can’t find much clear guidance on using the Membership tool with mvc to create accounts and roles etc. I tried the web configuration tool which works but I would like to administrate the site remotely. I used the aspnet_regsql tool so I can access the SqlMembershipProvider Schema in my Database. I also need to add more information to a user like profile info and a picture, would I add these to the membership tables or create separate tables for this? Any advice or help would be really helpful? Thanks Jemes

  • Access parent class from custom attribute

    - by madcapnmckay
    Hi, Is it possible to access a parent class from within an attribute. For example I would like to create a DropDownListAttribute which can be applied to a property of a viewmodel class in MVC and then create a drop down list from an editor template. I am following a similar line as Kazi Manzur Rashid here. He adds the collection of categories into viewdata and retrieves them using the key supplied to the attribute. I would like to do something like the below, public ExampleDropDownViewModel { public IEnumerable<SelectListItem> Categories {get;set;} [DropDownList("Categories")] public int CategoryID { get;set; } } The attribute takes the name of the property containing the collection to bind to. I can't figure out how to access a property on the parent class of the attribute. Does anyone know how to do this? Thanks

  • Asp.net Report Viewer - Custom filter parameters

    - by Chris
    Hi all, for a data warehouse project I need to know about some best practices regarding custom report viewer filters/parameters. Usually I use the standard parameter feature for reports, like multiple select boxes, check boxes, text boxes etc.. But for the current project some reports require more complex report parameters. E.g. a user wants to analyze some measures. For that the user needs to set a filter on a specific address. There are over 100.000 address to choose from, so he has to have the ability to search for an address (full text). Since such features cannot be done with the standard parameters, I will have to create custom params within a ASPX page which are then passed to the report viewer control. So my question is: Are there any best practices on how to create custom parameters? Did anyone had similar problems, if so, how did you solve it?

  • Rails + facebox + authlogic - how?

    - by Vitaly
    Hello, on my web site I want to have login/registration form in modal window done using facebox (jQuery plugin). What is better: Create view with one method and template that has form and refer facebox to this view. Create static HTML file in public directory and refer facebox to this static page. What I want to achieve is: Easy verification (like "user name already taken", "password confirmation doesn't match password" and stuff like that). Easy submit and redirect I'm new to Rails, I just know about forms verification in Django, so for Django I would probably choose option 1, but it might be another thing in Ruby.

  • Link a sequence with to an identity in hsqldb

    - by Candy Chiu
    In PostgreSql, one can define a sequence and use it as the primary key of a table. In HsqlDB, one can still accomplish creating an auto-increment identity column which doesn't link to any user defined sequence. Is it possible to use a user defined sequence as the generator of an auto-increment identity column in HsqlDB? Sample sql in PostgreSql: CREATE SEQUENCE seq_company_id START WITH 1; CREATE TABLE company ( id bigint PRIMARY KEY DEFAULT nextval('seq_company_id'), name varchar(128) NOT NULL CHECK (name < '') ); What's the equivalent in HsqlDB? Thanks.

  • How does 37signals job preview functionality work?

    - by slythic
    Hi all, I'm interested in getting a preview functionality working similar to how the 37signals job site does: http://jobs.37signals.com. Below are some screen shots of how it works. Step 1. Create your ad http://cl.ly/dfc4761b015c7f43c8ab (URL /jobs/new) Step 2. Preview your ad http://cl.ly/9c4b4041cfea83d8569e (URL /jobs/new/preview) Step 3. Publish your ad http://cl.ly/a58284d90fd380d2c26b (URL /listings/new/purchase?token=5198) So assuming you have Post model where Step 1 usually takes place in the new/create view/actions, how should one continue to Step 2 Preview and then after previewing, proceeding to the Step 3 publishing the post/ad? Do they actually save the ad/post in the database before continuing to Step 2 (Preview) but set a flag (like a boolean field called preview set to true)? It looks like they set a token paramater but I'm not sure what it's used for) I'm interested in this because it seems to go against the CRUD/REST and I thought it would be good to know how it worked. Thanks!

  • MVC Routes - How to get a URL?

    - by Seattle Leonard
    In my current project we have a notification system. When an oject is added to another objects collection, an email is sent to those who are subscibed to the parent object. This happens on the object layer and not in the View or Controller. Here's the problem: Although we can say who created what with what information in the email, we cannot embed links to those objects in the email because in the object layer there is no access to a UrlHelper. To construct a UrlHelper you need a RequestContext, which again does not exist on the object layer. Question: I want to make a helper class to create the url's for me. How can I create an object that will generate these urls without a request context? Is it possible?

  • Django design question: extending User to make users that can't log in

    - by jobrahms
    The site I'm working on involves teachers creating student objects. The teacher can choose to make it possible for a student to log into the site (to check calendars, etc) OR the teacher can choose to use the student object only for record keeping and not allow the student to log in. In the student creation form, if the teacher supplies a username and a password, it should create an object of the first kind - one that can log in, i.e. a regular User object. If the teacher does not supply a username/password, it should create the second type. The other requirement is that the teacher should be able to go in later and change a non-logging-in student to the other kind. What's the best way to design for this scenario? Subclass User and make username and password not required? What else would this affect?

  • Custom control packaging

    - by CSharpened
    Quick question: You are building a setup for your application. The application contains a custom control developed by you, which will be shared across multiple applications. How should you package the custom control? Package the control in a Merge Module (.msm) and add the .msm file to a Windows Installer project. Package the control into a cabinet project (.cab) and add the .cab file to a Windows Installer project. Create a separate directory for the control and then package it in a Windows Installer project along with the rest of the project files. Package the control as a Web setup project and create a link to that project from the Windows Installer project. Any ideas?

  • Creating a Dynamic Image using Friends pictures

    - by Narendra Rajput
    I am working on a Facebook for which I need to get all the Profile Pictures of Friends of the users. Which I did using FQL query. I need these images for creating a poster of all the Friends Profile pics along tags in them. For that I need to create a Dynamic poster for every user with their Friends tagged in them. I tried using the GD Library for PHP. I tried with the imagecreatefromjpeg() function of php for which I can use one image and pass it to the main image. But here I have more than 1 images (average about 100 images) depending on the number of friends the user has. What function do I need to create this dynamic poster ? Please any help would be appreciated !!

  • Unexpected key-value behavior in a Core Data Context

    - by ????
    If I create an array of strings (via key-value coding) containing the names of a Managed Object entity's attributes which are stored in the App Delegate the first time, I get an array of NSStrings without any problems. If I subsequently make the same call later from the same entry point in code, that same collection becomes an array of NULL objects- even though nothing in the Core Data Context has changed. One unappealing work-around involves re-creating the string array every time, but I'm wondering if anyone has a guess as to what's happening behind the scenes. // Return an array of strings with the names of attributes the Activity entity - (NSArray *)activityAttributeNames { #pragma mark ALWAYS REFRESH THE ENTITY NAMES? //if (activityAttributeNames == nil) { // Create an entity pointer for Activity NSEntityDescription *entity = [NSEntityDescription entityForName:@"Activity" inManagedObjectContext:managedObjectContext]; NSArray *entityAttributeArray = [[NSArray alloc] initWithArray:[[entity attributesByName] allValues]]; // Extract the names of the attributes with Key-Value Coding activityAttributeNames = [entityAttributeArray valueForKeyPath:@"name"]; [entityAttributeArray release]; //} return activityAttributeNames; }

  • C# Generics Casting

    - by Nippysaurus
    Visual sutdio 2008 has the ability to automatically create unit test stubs. I have used this to create some basic unit tests, but I am confused by something: private class bla : BaseStoreItem { // } /// <summary> ///A test for StoreData ///</summary> public void StoreDataTestHelper<T>() where T : BaseStoreItem { FileStore<T> target = new FileStore<T>(); // TODO: Initialize to an appropriate value BaseStoreItem data = new bla(); target.StoreData(data); } [TestMethod()] public void StoreDataTest() { //Assert.Inconclusive("No appropriate type parameter is found to satisfies the type constraint(s) of T. " + // "Please call StoreDataTestHelper<T>() with appropriate type parameters."); StoreDataTestHelper<bla>(); } Why do I get "Error: Cannot convert type 'StorageUnitTests.FileStoreTest.bla' to 'T'" when T is type "bla"? I know "bla" is not a good function name, but its just an example.

  • How to best share an NSMenu between multiple NSPopUpButton instances

    - by Frank R.
    Hi, I need to share the same NSMenu instance between multiple popup buttons. When I create an NSPopUpButton in IB, a new menu is automatically created and inserted as a child of the NSPopUpButtonCell. At the moment, I simply create an IBOutlet NSMenuItem* standardMenu member in my MainController and connect the "menu" outlets of the popup buttons to this, but this leaves the "fake" menus in the hierarchy. Surely, there's a clean way of doing this from inside IB? Thanks in advance for any advice you might be able to give.

  • How to generate multiple Alter Scripts in SSMS

    - by dannyRods
    I'm using sql server management studio 2008 to try and generate an alter script for each of my stored procedures in order to save the scripts for each revision. I can easily generate an alter script for each individual procedure, but I'm not trying to go through a hundred stored procedures manually. I know that SSMS has an automated generate scripts function under task, but the only options are create, drop and create, and drop. I cant seem to figure out how to enable alter. I've already searched through many SO articles, as well as a little digging in msdn, and I've come up with nothing. I'm hoping that the fine people of stackoverflow will be up to the challenge. Thanks in advance

  • Storing Object Types in Variable then Initializing

    - by Jon Mattingly
    Is there a way in Objective-C to store an object/class in a variable to be passed to alloc/init somewhere else? For example: UIViewController = foo foo *bar = [[foo alloc] init] I'm trying to create a system to dynamically create navigation buttons in a separate class based on the current view controller. I can pass 'self' to the method, but the variable that results does not allow me to alloc/init. I could always import the .h file directly, but ideally I would like to make reusing the code as simple as possible. Maybe I'm going about this the wrong way?

  • Is it possible to run JavaScript and also edit image maps using Design View in Dreamweaver?

    - by Mike Eng
    I'm using Dreamweaver CS5.5 for an HTML prototype that is built with image-mapped screenshots. I am using JavaScript to dynamically include the appropriate main image, and the navigation is done with image maps. Is it possible to have the Dreamweaver "Design View" run JavaScript initially (which will set the main image) and also allow me to edit the image maps in place (so I can see them placed over the correct main image)? I found some references to the "Live View" feature, which runs JavaScript successfully, but I cannot see or edit image maps in "Live View".

  • Retractable button bar using animations

    - by AndroidDev
    I want to create a button bar that is retractable: when the user clicks on a special "handle" button, the button bar should slide out of view partially so only the handle remains visible. When the bar is in retracted state only the handle is visible. Clicking on the handle should "slide out" the button bar so it is completely visible again. Ideally, the bar would start out in retracted state. I have tried some approaches using TranslateAnimation, including using a layout animation or calling "View.startAnimation" when the handle is clicked, but no luck so far. Do you guys have any tips how to approach this? Is there any decent documentation out there regarding Android animations? The documentation I find is sketchy at best. For instance, I found examples that cause a view to slide into view automatically using TranslateAnimation and a LayoutAnimationController when calling "addView", but when I call removeView no animation seems to be triggered at all, even if I set an animation that should create the opposite motion.

  • Service Broker error message: Dialog security is unavailable for this conversation because there is

    - by yanigisawa
    I am getting this error in my sys.transmission_queue table whenever I attempt to send a SQL Service Broker message between two different SQL Server servers. (i.e. the databases are on two different physical machines) Dialog security is unavailable for this conversation because there is no security certificate bound to the database principal (Id: 5). Either create a certificate for the principal, or specify ENCRYPTION = OFF when beginning the conversation When this error refers to "database principal" what is it referring to? (the "master" database? dbo user?) I've used the CREATE CERTIFICATE command, backed up the certificate and created a same named certificate on the other server with the backup .cer file from the first server, but I keep getting this message. Any help would be appreciated in getting me pointed in the right direction. I must be missing something obvious. FYI, in my development environment, both the initiating and target databases were on the same physical server, and same SQL instance, and everything was working fine.

  • Does Python Django support custom SQL and denormalized databases with no Foreign Key relationships?

    - by Jay
    I've just started learning Python Django and have a lot of experience building high traffic websites using PHP and MySQL. What worries me so far is Python's overly optimistic approach that you will never need to write custom SQL and that it automatically creates all these Foreign Key relationships in your database. The one thing I've learned in the last few years of building Chess.com is that its impossible to NOT write custom SQL when you're dealing with something like MySQL that frequently needs to be told what indexes it should use (or avoid), and that Foreign Keys are a death sentence. Percona's strongest recommendation was for us to remove all FKs for optimal performance. Is there a way in Django to do this in the models file? create relationships without creating actual DB FKs? Or is there a way to start at the database level, design/create my database, and then have Django reverse engineer the models file?
