  • iPhone development: Best method to allow user to chose search scope

    - by Mark Pemburn
    Hi, I'm developing my first iPhone app and want to allow the user to select the scope of their search in a more complex way than the 'scope buttons' permit. The app is related to wines and I want to the user to be able to select the 'color' (Red, White, Blush, etc.) first, and then select the type/varietal within that category. Right now, I'm using the UISearchBar's scope buttons for the colors and tapping the button opens a view with the selection of colors. This is okay except that once the 'Red' button has been selected, I can't select it a second time to change my choice of type (e.g., change from 'Merlot' to 'Syrrah', etc.) If there's a better way to do this, I'm willing to scrap my method and start from scratch. Thanks!

  • iPhone Development - Query related records using CoreData

    - by Mustafa
    I have a case where i have three entities with one-to-many and one-to-many relationships: Entity A (Entity B relationhip), Entity B (Entity A relationship, Entity C relationship), Entity C (Entity B relationhip) I have the reference of Entity A, and now i want to fetch all the related Entity C records. How can i do that? (with least amount of code) Edit: Here's another way to put it. Can we perform joins with CoreData. For example, (and this is a very crude example), We have a following entity-relationship: Grand Parent (1)---(m) Parent Parent (1)---(m) Child So, now if i have "Albert" the Grand Parent, and i want to get all his grand children, how can i do that?

    I'm writing a project and I need to use a certain number of journal articles. I'm having real trouble finding journal articles on RAD though. It seems to be mostly books that I can find. Can anyone recommend any good articles to get me started?

  • Login to SQL Server Express via development environment (VS2010)

    - by Sanarothe
    Seems like I'm missing something simple, but my attempts to connect to SQL Server Express have failed. I feel like I need to add privileges for my account but I'm not sure where to do it. Dev Env: VS 2010 (Web) SQL: Sql Server Express 2008 OS: XP Trying to open a connection to database returns: Cannot open database "|DataDirectory|DropData.mdf" requested by the login. The login failed. Login failed for user 'devel.' I created the database using the interface in VS 2010 (Add new item - DB File) but my ASP.Net class only covered design-time access and not access in code, so I'm not familiar with what to do. I created a user (Devel) using SQL Server Management Studio to avoid connecting as SA, but couldn't figure out how to give any SQL-level access rights to this account. Any ideas? Thanks, Cameron

  • How do people charge friends for development projects?

    - by Crashalot
    A friend has begged our consulting firm several times to build an iPhone app. We are reluctant to jeopardize the friendship and charge market rates. At the same time, we're so busy it would be imprudent not to charge fairly. We tried referring her to other shops, but she doesn't feel comfortable with anyone but us. How do people charge friends? Since I'm asking about fees, I'm also curious to know if people charge on a fixed-price basis or hourly basis? Thanks!

  • iPhone Development: Get images from RSS feed

    - by Matthew Saeger
    I am using the NSXMLParser to get new RSS stories from a feed and am displaying them in a UITableView. However now I want to take ONLY the images, and display them in a UIScrollView/UIImageView (3 images side-by side). I am completely lost. I am using the following code to obtain 1 image from a URL. NSURL *theUrl1=[NSURL URLWithString:@"http://farm3.static.flickr.com/2586/4072164719_0fa5695f59.jpg"]; JImage *photoImage1=[[JImage alloc] init]; [photoImage1 setContentMode:UIViewContentModeScaleAspectFill]; [photoImage1 setFrame:CGRectMake(0, 0, 320, 170)]; [photoImage1 initWithImageAtURL:theUrl1]; [imageView1 addSubview:photoImage1]; [photoImage1 release]; This is all I have accomplished, and it works, for one image, and I have to specify the exact URL. What would you recommend I do to accomplish this?

  • XAMPP or MAMP on Mac OS X 10.6.2 (Snow Leopard)

    - by Steve
    I just bought a new MacBook Pro which comes with Snow Leopard 10.6.2 (Mac OS X 10.6.2). I am used to using XAMPP as my local development server on XP. Since Mac OS X is based on Unix, I was thinking on activating/installing all the necessary stuff as I would normally do on Linux. However, I am not quite ready to be playing around with the system at this point so having an external package would be a nice temporary solution I think. The question is whether I should go with MAMP or XAMPP. Does anybody have any suggestions? The Pro and Cons I suppose. As far as I know, Mac OS X comes with Apache2 and PHP5. Would MAMP or XAMPP modify the existing Apache and PHP installation? Any comments on how I should proceed? PS: Eventually I would use the default installation of Apache and PHP, and install a binary package of MySQL but time for development is an essence and I don't have time to familiarize myself with Mac OS X.

  • Amazon EC2 Development Stack

    - by sirmak
    I want to use EC2 for some reasons and EC2 provides both windows and linux deployments, but linux is much cheaper (linux reserved instances are approx. %63-%85 price of windows ones and spot instances are %50 cheaper for linux). I need a type safe lang and mainstream platform and I prefer to use .net/c# stack (but not mono for some reasons), but in this situation java seems a better fit for the future (when ec2 instance counts begin to increase). So, is it worth to use .net ? best regards,

  • Suggest product catalog script/framework in PHP which doesn't displays product price

    - by Amit Kumar Jha
    Hey all, I am new to web development and have this project in hand where in I have to build a product catalogue. I don't want any cart functionality or other such features, I just want to display the products,their specifications and images etc. on the website and give my client an admin panel to manage products. Now I looked into various PHP shopping cart scripts but couldn't find a way to remove price info from the display. I am not experienced enough in web development to make a product catalogue from scratch so if you guys could point me out in right direction I would be very grateful. If you could give me link to some shopping cart or cataloguing script or any other way to accomplish the task it would help me out a lot.. Thanks in advance to all those who reply.

  • Implementing a Stack using Test-Driven Development

    - by devoured elysium
    I am doing my first steps with TDD. The problem is (as probably with everyone starting with TDD), I never know very well what kind of unit tests to do when I start working in my projects. Let's assume I want to write a Stack class with the following methods(I choose it as it's an easy example): Stack<T> - Push(element : T) - Pop() : T - Seek() : T - Count : int - IsEmpty : boolean How would you approch this? I never understood if the idea is to test a few corner cases for each method of the Stack class or start by doing a few "use cases" with the class, like adding 10 elements and removing them. What is the idea? To make code that uses the Stack as close as possible to what I'll use in my real code? Or just make simple "add one element" unit tests where I test if IsEmpty and Count were changed by adding that element? How am I supposed to start with this?

  • Is there any need to get a Computer Science degree?

    - by Tom Moseley
    I've been a software developer for 20 years. i've been involved in language development and large data warehouse development. I've worked for start-ups that have gone public, and for government contractors, and I've written a published programming book. My knowledge is either self-taught or on-the-job. I've worked with some of the best and brightest, and they taught me well. I'm back in school now, and am weighing my options, deciding between a Computer Science and a business degree. My question is this. What do I gain, at this point in my career, by earning a Computer Science degree? I just don't know if a Computer Science degree, at this point, is a value-add on my resume. Edit: I'm working on completing an undergraduate degree.

  • best way to set up a VM for development (regarding performance)

    - by raticulin
    I am trying to set up a clean vm I will use in many of my devs. Hopefully I will use it many times and for a long time, so I want to get it right and set it up so performance is as good as possible. I have searched for a list of things to do, but strangely found only older posts, and none here. My requirements are: My host is Vista 32b, and guest is Windows2008 64b, using Vmware Workstation. The VM should also be able to run on a Vmware ESX I cannot move to other products (VirtualBox etc), but info about performance of each one is welcomed for reference. Anyway I guess most advices would apply to other OSs and other VM products. I need network connectivity to my LAN Guest will run many java processes, a DB and perform lots of file I/O What I have found so far is: HOWTO: Squeeze Every Last Drop of Performance Out of Your Virtual PCs: it's and old post, and about Virtual PC, but I guess most things still apply (and also apply to vmware). I guess it makes a difference to disable all unnecessary services, but the ones mentioned in 1 seem like too few, I specifically always disable Windows Search. Any other service I should disable?

  • Blackberry development on scripting language ?

    - by zvr
    From what I've seen, the preferred way to develop Blackberry applications is Java. Is this the only way? I'm dreaming of a rapid application environment where you can create GUIs (using the Blackberry UI components). Something like a port of Tcl/Tk on Blackberry... or Python/Tkinter... or something new, but similar. Does something like that exist ? (I doubt it) Can something like that exist ? (i.e., given the money, is it feasible/reasonable/...)

  • Sharepoint Foundation 2010 installation problems

    - by Robert Koritnik
    I'm having problems installing development machine for Sharepoint (Foundation) 2010. This is what I did so far on the same machine: Installed a clean Windows 7 x64 with 4GB of RAM without being part of any domain. Just a simple standalone machine. Enabled IIS related features as described here except IIS6 related ones (two of them) Installed SQL Server 2008 R2 Development Edition (DB Engine and Writer being enabled but not SQL Agent) Installed Visual Studio 2010 Premium Started installing Sharepoint Foundation 2010 with first extracting files, changing config to enable Windows 7 installation and then installed it as Server Farm (then Complete) to avoid installing SQL Express. Created a separate SPF_CONFIG local user with Logon on as a service right. Opened SPF Management Shell and run New-SPConfigurationDatabase so I am able to use a non-domain username (SPF_CONFIG that I created in the previous step) But all I get is this: The outcome after this error is: Database Sharepoint2010Config is created User SPF_CONFIG is added to SQL Server and attached to this newly created database as dbowner and checking SQL server security logins this user has following rights: dbcreator securityadmin public

  • How to do test-first development with MVVM

    - by Thorsten79
    How do you build WPF MVVM applications and user controls test-first? I find myself writing ungodly amounts of XAML with DataTemplates before I even get to unit-testing my viewmodels. Should I develop the whole viewmodel system first before even writing XAML for it? Any help appreciated.
