• How do I get hyphens in my attribute names in Flex?

  - by John Leonard

  Flex has an issue with hyphens in xml. I need to generate an xml object with hyphens in the attribute for a Google Checkout implementation. I can get away with: var xml:XML = <item-description/>; and var xml:XML = <item-description the-name="foo"/>; but what I need to do is set the value of an attribute like this: var timestamp:String = methodToGetMyTimestampString(); var xml:XML = <item-desc/>; xml@start-date = timestamp; but I can't do that. Since flex doesn't like the hyphens, I don't know how to get or set attributes with hyphens in the name.

• Sending information back from delegate [iPhone]

  - by Andy

  I'm using NSXMLParser in my RootViewController.m file. NSXMLParser *xmlParser = [[NSXMLParser alloc] initWithData:response_data]; [xmlParser setDelegate:self]; [xmlParser parse]; [xmlParser release]; I'm also implementing this method to add entries to a dictionary defined in RootViewController.m for later use: - (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName attributes:(NSDictionary *)attributeDict However, I'd like to get more than one XML file and do different things when the file has finished; this sounds like I need to use external files as delegates. My question is: If I have the following implementation files (& their header files): RootViewController.m XMLDelegate1.m XMLDelegate2.m and set the ith NSXMLParser delegate to be XMLDelegatei.m, and get those files to return an NSDictionary that I can then add to the NSDictionary defined in RootViewController.m. I guess there are two methods of doing this: Use a method that I don't know about; or Use a better workflow I suspect it's 2, but hope it's 1. Thanks, Andy

• adding custom fields dynamically to a model

  - by pankajbhageria

  I have a model called List which has many records: class List has_many :records end class Record end The table Record has 2 permanent fields: name, email. Besides these 2 fields, for each List a Record can have 'n' custom fields. For example: for list1 I add address(text), dob(date) as custom fields. Then while adding records to list one, each record can have values for address and dob. Is there any ActiveRecord plugin which provides this type of functionality? Or else could you share your thoughts on how to model this? Thanks in advance, Pankaj

• to-many Core Data fetch request behaves oddly with a new store

  - by Giao

  I have two entities, Department and Person. Department has a to-many relationship to Person. The Person entity has a hireDate property. I'm using the predicate "count(person) = 0 OR none person.hireDate %@" to find Departments without any Persons in them or Departments that haven't hired anyone since a recent date. When the app first starts up (new user experience) and Departments are inserted and no Person have been inserted, the fetch request with this predicate returns nothing. However, if I create insert a new Person entity and delete it, then save the store, the fetch request will return all the Departments. I've found a work around where, I just insert a new Person and delete it, then save the store, the fetch request as I expected it to work. I've found that inserting a new Person and deleting it without saving will not correct the problem. Is this a bug with Core Data or is this a bug with how I've designed my app?

• Android-iPhone single codebase

  - by Lorenzo

  Is there a way, apart from using HTML and JavaScript on a web control, to have an (almost) single codebase for an application that should run on iOS and Android? The big issue is of course that they use a different language (Java for Android, Objective-C for iOS) for application development. It would be nice to have some sort of meta-language that will be translated in Java and in Objective-C. What about Flash? Adobe wasn't supposed to release a tool to create flash-based apps in iOS?

• How should the Version field be used in Trac?

  - by Eric

  I use Trac to track bugs, and future changes in my software projects. Tickets in Trac have a "Version" field and I'm trying to figure out the best way to use this field. Say I find a series of bugs in version 1.0 of my software. I create tickets in track for each and assign them to version 1.0. Now say I fix some of the bugs, and add some of the new features and release version 1.1. But some of the old 1.0 bugs are still in 1.1. Should I change their corresponding tickets to version 1.1 because they also now exist in 1.1? Or should I leave them set to version 1.0 as a way of tracking what version the bug was found in, and just assume that any open tickets in older versions still exist in newer versions?

• Develop Rails app on Mac using with TextMate Tutorial

  - by Meltemi

  I've found this a somewhat dated tutorial for developing a Rails application on Leopard with XCode. Wondering if anyone knows of a more up-to-date (ideally Mac based) tutorial that uses TextMate (or XCode if it's indeed preferred, or even just the command line). TextMate is appealing to me but wondering how to work scrips like ruby script/generate controller etc. into workflow or if switching between command-line & TextMate is standard operating procedure... If it matters were have Snow Leopard clients and Leopard Servers at our disposal. Thanks..

• Is it possible to use HTTPS certificates for licensing?

  - by Ton van den Heuvel

  I am working on an application with multiple clients and a server running various web-services for the clients. To implement licensing I am thinking about using HTTPS as a protocol for the web-services using certificates that are issued by our company. By influencing the expiration date of a certificate for a client we can prevent them from using our software after their license term. It this possible and does it make sense to you? Additional information: I am planning on using Qt/C++ for the clients, and the Twisted framework for the web-services.

• Does a program exist for checking two similar directories for file differences?

  - by John Sullivan

  Is there a program to compare one folder and all subfolders to another folder and all subfolders for differences in the files contained therein (presence, absence of files, size and list of filenames)? Example of usage: I have 100 DLL files from environment 1 and I want to check if any of them are different (in size and date modified) from the 100 DLL files in environment 2. So I copy and paste all the DLLs in environment 1 into directory A, and all the DLLs in environment 2 into directory B. I then run my "directory comparison" program on directories A and B and find out that, aha, here is a list of 7 DLLs that have different modified dates and times between the two directories. EDIT: OS is windows XP

• Devising a test strategy

  - by Simon Callan

  As part of a new job, I have to devise and implement a complete test strategy for the companies new product. So far, all I really know about it is that it is written in C++, uses an SQL database and has a web API which is used by a browser client written using GWT. As far as I know, there isn't much of an existing strategy, except for using Python scripts to test the web API. I need to develop and implement a suitable strategy for unit, system, regression and release testing, preferably a fully automated one. I'm looking for good references for : Devising the complete test strategy. Testing the web API. Testing the GWT based application. Unit testing C++ code. In addition, any suitable tools would be appreciate

• algorithm advice for finding maximum items within a time period

  - by darren

  Hi everyone. I have a database schema that is similar to the following: | User | Event | Date |--------|---------------|------ | 111 | Walked dog | 2009-10-1 | 222 | Walked dog | 2009-10-2 | 333 | Fed Fish | 2009-10-5 | 222 | Did Laundry | 2009-10-6 | 111 | Fed Fish | 2009-10-7 | 111 | Walked dog | 2009-10-18 | 222 | Walked dog | 2009-10-19 | 111 | Fed Fish | 2009-10-21 I would like to produce a query that returns the maximum number of times a user performs some action within a time period. For example, given a time period of 5 days, what is the maximum number of times user 111 walked the dog? The most obvious solution would be to start at some zero point and move forward each day, summing up 5 day periods along the way, then taking the maximum total out of all the 5 day windows. the approach seems incredibly costly however. I would appreciate any suggestions you may have.

• Comparing two java objects on fly (data type not known)

  - by Narendra

  Hi All, I need to compare different data objects. Can any one tell me how can i do this. I don't know what are the data types i will get priorly. If i need to use any util from apache commons then please give reference to it. At present I am using .equals() for comparing equality of objects .It is working fine when I am comparing quality for two strings. If i am comparing java.sql.date data type then it is showing unequal even though both contains same values. Can any one suggest me on this regard. Thanks, Narendra

• Best way to structure AJAX for a Zend Framework application

  - by John Nall

  Sorry, but there's a lot of outdated and just plain bad information for Zend Framework, since it has changed so much over the years and is so flexible. I thought of having an AJAX module service layer, with controllers and actions that interact with my model. Easy, but not very extensible and would violate DRY. If I change the logistics of some process I'll have to edit the AJAX controllers and the normal controllers. So ideally I would load the exact same actions for both javascript and non-javascript users. I have thought about maybe checking for $_POST['ajax'], if it is set I would load a different (json'y) view for the data. Was wondering how/a good way to do this (front controller plugin I imagine?) or if someone can point me to an UP TO DATE tutorial that describes a really good way for building a larger ajax application. thx

• How many parameters in C# method are acceptable?

  - by Valentin Heinitz

  I am new to C# and have to maintain a C# Application. Now I'v found a method vaving 32 Parameters (not auto-generated code). From C/C++ I remember the rule of thumb "4 Parameters". It may be an old-fashioned rule rooting back to old 0x86 compilers, where 4 Parameters could be accomodated in registers (fast) or on stack otherwise. I am not concerning about performance, but I do have a feeling, that 32 parameters per functions are not easy to maintain even in C#. Or am I completly not up to date? What is the rule of thumb for C#? Thank you for any hint!

• Working with the Objective-C/Cocoa flat namespace

  - by Stephen Blinkhorn

  I've not found anything that addresses my specific name space question as yet. I am working on some AudioUnit plug-ins featuring Cocoa based GUIs. The plug-ins use a common library of user interface classes (sliders, buttons etc) which are simply added to each Xcode project. When I recompile and distribute updates it is pretty much guaranteed that at least one user interface class will have been updated since the last release. If the user launches an older plug-in before an updated plug-in then the old Cocoa classes are already loaded into the run time and the plug-in attempts to use the older implementations - often resulting in a failure one way or another. I know frameworks are the intended solution but the overhead and backwards compatibility issues are not ideal. I prefix all class names where possible but what options do I have to ensure that each plug-in contains unique class names for the shared user interface classes?

• Processing a property in linq to sql

  - by Mostafa

  Hi It's my first LINQ TO SQL Project , So definitely my question could be naive . Till now I used to create new property in Business Object beside of every DateTime Property , That's because i need to do some processing in my DateTime property and show it in special string format for binding to UI Controls .Like : private DateTime _insertDate; /// /// I have "InertDate" field in my Table on Database /// public DateTime InsertDate { get { return _insertDate; } set { _insertDate = value; } } // Because i need to do some processing I create a readonly string property that pass InsertDate to Utility method and return special string Date public string PInsertDate { get { return Utility.ToSpecialDate(_insertDate); } } My question is I don't know how to do it in LINQ . I did like follow but i get run time error. ToosDataContext db = new ToosDataContext(); var newslist = from p in db.News select new {p.NewsId,p.Title,tarikh =MD.Utility.ToSpecialDate( p.ReleaseDate)}; GridView1.DataSource = newslist; GridView1.DataBind();

• Flex 3.0 Drag and Drop

  - by C-Man

  Hi all! I have encountered a problem in a Flex application. I have implemented drag and drop support from a List to a Canvas, and I DragManagers doDrag() - with.a proxy-image. In my custom DragDrop event handler, i place a new item on the Canvas. I use the event.localX/localY to position the new item. It is working ok, but the problem is that I want the "new" image to appear exactly where the proxy-image is when i release the mouse button (x/y -wise). Can I somehow get the proxys X,Y location. I thought that DragManager would have a reference to it but I can´t find it. Thanks /C

• Tracking EXC_BAD_ACCESS on iPad

  - by Aleks

  I've been using this code to create my UIWindow UIMyWindow* win = [[UIMyWindow alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]]; UIMyWindow isn't anything special it just has a pointer to a C++ class that does some wrapping of ObjectiveC. Recently my application start crashing after adding some line of code that doesn't have to do anything with the error. The line of code that I added is just allocating a C++ object but the program execution never reaches this line. Interesting enough my code works in Release. My only guess is that I made some memory corruption on a completely different place. My questions are: What type of memory corruption that can be? And is there some good practices to track them down?

• Converting an AWT application to SWT/JFace

  - by data

  I am currently toying with the idea of converting a small/medium sized project from AWT to SWT, although Swing is not totally out of the picture yet. I was thinking about converting the main window to an SWT_AWT bridge object, but I have no idea how the semantics for this work. After that, I plan to update dialog for dialog, but not necessarily within one release. Is this possible? Has someone done a conversion like this and can give me some hints? Is there maybe even a tutorial somewhere out there? Is there maybe even a tool that can automate parts of this? I have tried googling, but to no avail. Update: One additional thing is: Currently, this is a netbeans project. Might be of help or not, I don't know.

• Request attributes in jsf / icefaces behaves strange (survive request end)

  - by hubertg

  I have the following code in a listener method: FacesContext.getCurrentInstance().getExternalContext().getRequestMap().put("time", new Date()); When a button is clicked the following code is executed System.out.println(FacesContext.getCurrentInstance().getExternalContext().getRequestMap().get("time")); One could except that "time" is null when the listener was not executed while processing the current request, but: it seems like the "time" object survives the request processing. So when "time" has been set sometimes in the past it stays there... can anybody explain this? Thanks.

• Why is autorelease especially dangerous/expensive for iPhone applications?

  - by e.James

  I'm looking for a primary source (or a really good explanation) to back up the claim that the use of autorelease is dangerous or overly expensive when writing software for the iPhone. Several developers make this claim, and I have even heard that Apple does not recommend it, but I have not been able to turn up any concrete sources to back it up. SO references: autorelease-iphone Why does this create a memory leak (iPhone)? Note: I can see, from a conceptual point of view, that autorelease is slightly more expensive than a simple call to release, but I don't think that small penalty is enough to make Apple recommend against it. What's the real story?

• Is block style really this important?

  - by Jack Roscoe

  I just watched a video of Douglas Crockford's presentation about his 2009 book JavaScript: The Good Parts. In the video, he explains that the following block is dangerous because it produces silent errors: return { ok: false }; And that it should actually be written like this (emphasising that although seemingly identical the behavioural difference is crucial): return { ok: false }; You can see his comments around 32 minutes into the video here: http://www.youtube.com/watch?v=hQVTIJBZook&feature=player_embedded#!&start=1920 I have not heard this before, and was wondering if this rule still applies or if this requirement in syntax has been overcome by JavaScript developments since this statement was made. I found this very interesting as I have NOT been writing my code this way, and wanted to check that this information was not out of date.
