• Need an algorithm to group several parameters of a person under the persons name

  - by QuickMist

  Hi. I have a bunch of names in alphabetical order with multiple instances of the same name all in alphabetical order so that the names are all grouped together. Beside each name, after a coma, I have a role that has been assigned to them, one name-role pair per line, something like whats shown below name1,role1 name1,role2 name1,role3 name1,role8 name2,role8 name2,role2 name2,role4 name3,role1 name4,role5 name4,role1 ... .. . I am looking for an algorithm to take the above .csv file as input create an output .csv file in the following format name1,role1,role2,role3,role8 name2,role8,role2,role4 name3,role1 name4,role5,role1 ... .. . So basically I want each name to appear only once and then the roles to be printed in csv format next to the names for all names and roles in the input file. The algorithm should be language independent. I would appreciate it if it does NOT use OOP principles :-) I am a newbie.

• Using java classes in Grails

  - by RN

  I have a Java\Spring\Hibernate application - complete with domain classes which are basically Hibernate POJOs There is a piece of functionality that I think can be written well in Grails. I wish to reuse the domain classes that I have created in the main Java app What is the best way to do so ? Should I write new domain classes extending the Java classes ? this sounds tacky Or Can I 'generate' controllers off the Java domain classes ? What are the best practices around reusing Java domain objects in Grails\Groovy I am sure there must be others writing some pieces in grails\groovy If you know about a tutorial which talks about such an integration- that would be awesome !!! PS: I am quite a newbie in grails-groovy so may be missing the obvious. Thanks !!!

• Windows authentication through IE - specify the domain

  - by Chris W

  This question really relates to allowing to logon to a SharePoint installation from home but I guess it's a general IIS security question. When the login box pops up to collect the windows credentials the user can just type in their user name on Safari/Chrome/FF and they can login correctly. On IE authentication fails as it seems to pass their local machine name by default and the user needs to replace this with domain\user. Not a big problem in some cases but we'd prefer it if the users didn't have to enter the domain name portion. Is this simply a feature of IE that we can't control or is their something we can do with IIS/AD etc that will allow us to provide a default domain if one isn't specified?

• Changing value of a Numeric Stepper

  - by REDDY

  Hi, I am a newbie to Flex and programming. I am trying something where I have 2 Numeric Steppers. One numeric stepper holds values from 0-230 and the other from 0.00-0.99. My question is how to change the value of the first numeric stepper when the second numeric stepper goes from 0.99 to 0.00. Suppose the first numeric stepper has a value 10 and the second numeric stepper is being incremented continuously. As it reaches 0.99 and on mouse up on the up arrow, 10 should change to 11 and this numeric stepper goes to 0.00. Could anyone help me out with some code or suggestion? Thanks is advance, REDDY

• Winforms - Visually remove button click event

  - by Wayne Koorts

  .NET newbie alert Using Visual C# 2008 Express Edition I have accidentally created a click event for a button. I then deleted the automatically-created method code, which resulted in an error saying that the function, which had now been referenced in the form loading code, could no longer be found. Deleting the following line from the Form1.Designer.cs file's InitializeComponent() function... this.btnCopy.Click += new System.EventHandler(this.btnCopy_Click); ... seems to do the trick, however, it makes me feel very dirty because of the following warning at the beginning of the #region: /// Required method for Designer support - do not modify /// the contents of this method with the code editor. I haven't been able to find a way to do this using the form designer, which I assume is the means implied by this warning. What is the correct way to do this?

• ClickOnce Deployment online questions

  - by David Archer

  Hi all, Bit of a strange question, but how do ClickOnce deployments work from a web site? I seem to be having some problems with this. Basically, the setup file will download when you click the "install" button, but then some files are missing. Do you need to be on a Microsoft server to run ClickOnce deployments? I usually do deployments over a local server with UNC, and as this is the first time I've done one online I'm struggling a bit. Any newbie tutorials you can point me to would be great, and if I do need a special host for it, could you please recommend some? Cheers!

• Tips on deploying Ror

  - by notnoop

  How can I go about deploying a Rails app on a cluster of Amazon EC2 servers? Any recommended guides? I maintain a RoR app (currently hosted on Heroku) that uses a DB and DelayedJobs). The app has a large footprint, and needs to be distributed on a cluster most likely. Any tips would be appreciated. Are there Amazon AMIs that replicate some of Heroku's features (especially DJ)? P.S. I'm quite a Ruby newbie.

• In which DLL is the COM interface iStream defined?

  - by Youval Bronicki

  I'm a complete newbie to Windows and COM programming, trying to use com4j in order to call a COM object from Java. Com4j generates Java interfaces from COM definitions "often found in .ocx, .dll, .exe, and/or .tlb files" . It was easy for me to locate the .ocx file of my target COM object, but I have no clue regarding the standard interface iStream. Microsoft's documentation mentions OLE32.DLL ( c:\Windows\Windows32\Ole32.dll ?) , but neither the com4j generator nor oleviewer succeed in opening this file. Any hints?

  - by ile

  I followed instructions for mvc validation but I can't manage to solve this problem.... This is linq to sql model: I set Entity namespace to be CMS.Model If I try to declare partial class Article in Portal.Models namespace: public partial class Article { .... } Then, after using Article article somewhere in code I get following error: 'Article' is an ambiguous reference between 'Portal.Models.Article' and 'CMS.Model.Article' Portal is project name and CMS is area.... I followed these instructions I aslo created NerdDinner from scratch and in that example validation works. I can't figure out what am I doing wrong... someone noticed my mistake? Is it related with giving name to Entity namespace (in tutorial they used default one) Thanks in advance! PS I'd like to note that I'm c# newbie so I'm not really familiar with these partial classes

• Objective C Array and Object Release

  - by david

  Hi, I have a newbie question regarding when to release the elements of a NSArray. See following pseudo code: NSMutalbeArray *2DArray = [[NSMutableArray alloc] initWithCapacity:10]; for (int i=0;i<10;i++) { NSMutableArray *array = [[MSMutableArray alloc] initWithCapacity:5]; for (int j=0;j<5;j++) { MyObject *obj = [[MyObject alloc] init]; [array addObject:obj]; [obj release]; } [2DArray addObject:array]; [array release]; } // use 2DArray to do something [2DArray release] My question here is, when I release 2DArray, do I need to explicitly release each of its element (array) first? Also, before I release the "array" object, do I need to release each of its element (MyObject) first? I am new to Objective C. Please help. thanks.

• Best way for programmers to edit XAML

  - by JessicaB

  I was wondering how programmers chose to edit XAML. Most of the programmers I speak to seem to edit the raw XML, but that seems nuts to me since it is such a natural thing for a more visual editor (of course you often have to get down to the raw code ultimately, but isn't there a better way to lay out a grid, or edit a template, or add non c# triggers or manage commands? The one that really set me off was editing a menu -- Visual Studio 1.0 had a better menu editor for C++ than the raw XAML editing experience.) When I edit .aspx files I use a visual editor much of the time, and then for the raw stuff I get into the html code. I am aware of Expression Blend, but that seems far more focused on artistic types and GUI experts rather than programmers. Does anyone have recommendations for a better editor for XAML than VS? Especially so since VS seems to have real nasty problems with XAML editing too, like bugginess and poor performance? Appreciate your helping this XAML newbie.

• Edit Enterprise Calendar in Project Server 2010

  - by Chris W

  Has anyone been able to successfully edit the Standard calendar in 2010? I'm trying to change the working times as none of our admin accounts seem able to do it. We're running Project Server 2010 RTM on SharePoint 2010 RTM with Project Pro 2010. When I click the Edit Calendar button in PWA it triggers Project client to open up but it just opens up an empty project and I've not access to edit the Standard calendar using any of the published steps. It would be great to hear if someone has managed to do this so I can work out if it's a general glitch in this build or is it just a problem with out setup.

• Django : proper way to use model, duplicates!

  - by llazzaro

  Hello, I have a question about the proper, best way to manage the model. I am relative newbie to django, so I think I need to read more docs, tutorials,etc (suggestions for this would be cool!). Anyway, this is my question : I have a python web crawler, that is "connected" with django model. Crawling is done once a day, so its really common to find "duplicates". To avoid duplicates I do this : cars = Car.Objects.filter(name=crawledItem['name']) if len(cars) 0: #object already exists, update it car = cars[0] else: car = Car() #some non-relevant code here car.save() I want to know, if this is the proper/correct way to do it or its any "automatic" way to do it. Its possible to put the logic inside the Car() constructor also, should I do that? Thanks a lot!

• C# Class Design Question

  - by Soo

  This is a super newbie question, I've been programming for a while, but am just learning OOP. I have a class that works with user input via the C# console. There are different methods in this class to gather different input sets. I have another class that takes these input sets and puts them in a database. What is the best way to pass the input from my input class to my database insert class? My guess would be: Array1[] = inputClass.GetParameterSet1(); DatabaseInsertClass.InsertIntoDatabase1(Array1[]); Is there anything wrong with this or is there a better way to do this? Should I even have two classes (The database class could also take the user input)?

• Testing Django web app with Hudson and Selenium

  - by ycseattle

  This might be a newbie question for Hudson. I am trying to setup Selenium testing for my Django website in my Hudson CI server. The question is, the Hudson will use subversion to checkout my Django code into its own path, how do I "deploy" the code into the same server for testing? This is not a question about deploying django, but instead how to access the source file in hudson workspace. Most tutorials/blogs is about building and running tests, but I couldn't find useful information about how to setup the web application on the server to run the test against. 1) Should I write some shell script to copy the source files from the hudson workspace? Is there an environment variable to use to access the workspace? 2) Is there a tutorial on how to grab web app files in hudson workspace and deploy them? I am sure this apply for other technologies like PHP as well. Thanks!

• iTunes Apple Events API

  - by jldupont

  I'd like to control iTunes through Objective-C ( I just can't get Python appscript installed correctly on my OS/X 10.6.3 system ... that would have been my first choice ). From what I gather, the IPC on Cocoa is based on Apple Events : is there either: Online documentation on iTunes / Apple Events API ? Instrospection mechanism to get to iTunes API? I know about Applescript Editor / Open Dictionary functionality but I can't figure out how to translate the information I see into IPC calls. Note: I have already tried working out a solution through PyObjC but the main function I am after is track searching which I can't figure out. Disclaimer: OS/X super-newbie here.
