• Spring MVC with a rich client framework

  - by ziggy

  I have several applications that are structured as follows DataComponent WebComponent ThickClientComponent WebServices The DataComponent has all the functionality required to access the application's data so it contains the DAOs and the JPA entities. The other three modules are: WebComponent - A spring MVC application that uses the DataComponent for data acccess ThickClientComponent- A Swing application that uses the DataComponent for data access WebServices - A SOAP based services that also uses the DataComponent. All three projets have the DataComponent as a dependeny in their Maven POM file. I would like to use a rich client framework like RichFaces, icefaces or primefaces as i need to be able to use the rich components are available in rich client frameworks (i.e. trees, panel, drag and drop etc). I have looked around and i cant seem to find an example where a Spring MVC application uses a rich client platform. Is it possible? Are the rich client platforms a framework meaning that i have to use either Spring MVC or the rich client platform but not both? The DataComponent module is spring based.

• Own data format for the iPhone

  - by Stefan

  Hi, I would like to create my own data format for an iPhone app. The files should be similar structured as e.g. Apple's iWork files (.pages). That means, I have a folder with some files in it: The file 'Juicy.fruit' contains: Fruits ---> Apple.xml ---> Banana.xml ---> Pear.xml ---> PreviewPicture.png This folder "Fruits" should be packed in a handy file 'Juicy.fruit'. Compression isn't necessary. How could I achieve this? I've discovered some open source ZIP-libraries. However, I would like to to build my own data format with the iPhones built-in libs (if possible). Best regards, Stefan

• What guides or standards do you use for CVS in your team ?

  - by PaulHurleyuk

  I'm starting to do a small amount of development within my company. I'm intending to use Git for CVS, and I'm interested to see what guidelines or standards people are using around CVS in their groups, similar to coding standards are often written within the group for the group. I'm assuming there will be things like; Commit often (at least every day/week/meeting etc) Release builds are always made from the master branch Prior to release, a new branch will be created for Testing and tagged as such. only bug fixes from this point onwards. The final release of this will be tagged as such and the bug fixes merged back into the trunk Each developer will have a public repo New features should get their own branch Obviously a lot of this will depend on what cvs you're using and how you've structured it.

• What are all the disadvantages of using files as a means of communicating between two processes?

  - by Manny

  I have legacy code which I need to improve for performance reasons. My application comprises of two executables that need to exchange certain information. In the legacy code, one exe writes to a file ( the file name is passed as an argument to exe) and the second executable first checks if such a file exists; if does not exist checks again and when it finds it, then goes on to read the contents of the file. This way information in transferred between the two executables. The way the code is structured, the second executable is successful on the first try itself. Now I have to clean this code up and was wondering what are the disadvantages of using files as a means of communication rather than some inter-process communication like pipes.Is opening and reading a file more expensive than pipes? Are there any other disadvantages? And how significant do you think would be the performance degradation. The legacy code is run on both windows and linux.

• Which syntax is better for return value?

  - by Omar Kooheji

  I've been doing a massive code review and one pattern I notice all over the place is this: public bool MethodName() { bool returnValue = false; if (expression) { // do something returnValue = MethodCall(); } else { // do something else returnValue = Expression; } return returnValue; } This is not how I would have done this I would have just returned the value when I knew what it was. which of these two patterns is more correct? I stress that the logic always seems to be structured such that the return value is assigned in one plave only and no code is executed after it's assigned.

• Why use MySQL over flatfiles?

  - by John

  A friend and I were debating about whether he should use MySQL or a flatfile database for his website's backend. I told him to go with MySQL because it was structured, held records well, and was consistent. He on the other hand said that he would rather go for speed. Reading files is a lot quicker than connecting to MySQL and it made me wonder whether he was right. For example, why not just create a folder for each table, like so: users/ groups/ posts/, within the folders have the files named by ID (1, 2, 3) and then for the data use a format like so: username: John\npassword: e2fc714c4727ee9395f324cd2e7f331f\nemail: [email protected]? In other words, what are the advantages of MySQL over flatfiles?

• can i change the black background of an iphone app?

  - by Cristi Balu?a

  My app is structured like this, a single MainWindow with window backgroundColor to white(which doesn't appear anywhere anyway), and in this nib i have a UINavigationController which doesn't seems to have a backgroundColor. Any view controller is added from code and made from code and they have a gray background. What happens is that when i rotate the iphone and the views are rotating as well, i see a black background under my views. Can this be changed? It looks ugly especially if i have a photo that is rotating in the same time with my gray background.

• Silverlight/Web Service Serializing Interface for use Client Side

  - by Steve Brouillard

  I have a Silverlight solution that references a third-party web service. This web service generates XML, which is then processed into objects for use in Silverlight binding. At one point we the processing of XML to objects was done client-side, but we ran into performance issues and decided to move this processing to the proxies in the hosting web project to improve performance (which it did). This is obviously a gross over-simplification, but should work. My basic project structure looks like this. Solution Solution.Web - Holds the web page that hosts Silverlight as well as proxies that access web services and processes as required and obviously the references to those web services). Solution.Infrastructure - Holds references to the proxy web services in the .Web project, all genned code from serialized objects from those proxies and code around those objects that need to be client-side. Solution.Book - The particular project that uses the objects in question after processed down into Infrastructure. I've defined the following Interface and Class in the Web project. They represent the type of objects that the XML from the original third-party gets transformed into and since this is the only project in the Silverlight app that is actually server-side, that was the place to define and use them. //Doesn't get much simpler than this. public interface INavigable { string Description { get; set; } } //Very simple class too public class IndexEntry : INavigable { public List<IndexCM> CMItems { get; set; } public string CPTCode { get; set; } public string DefinitionOfAbbreviations { get; set; } public string Description { get; set; } public string EtiologyCode { get; set; } public bool HighScore { get; set; } public IndexToTabularCommandArguments IndexToTabularCommandArgument { get; set; } public bool IsExpanded { get; set; } public string ManifestationCode { get; set; } public string MorphologyCode { get; set; } public List<TextItem> NonEssentialModifiersAndQualifyingText { get; set; } public string OtherItalics { get; set; } public IndexEntry Parent { get; set; } public int Score { get; set; } public string SeeAlsoReference { get; set; } public string SeeReference { get; set; } public List<IndexEntry> SubEntries { get; set; } public int Words { get; set; } } Again; both of these items are defined in the Web project. Notice that IndexEntry implments INavigable. When the code for IndexEntry is auto-genned in the Infrastructure project, the definition of the class does not include the implmentation of INavigable. After discovering this, I thought "no problem, I'll create another partial class file reiterating the implmentation". Unfortunately (I'm guessing because it isn't being serialized), that interface isn't recognized in the Infrastructure project, so I can't simply do that. Here's where it gets really weird. The BOOK project CAN see the INavigable interface. In fact I use it in Book, though Book has no reference to the Web Service in the Web project where the thing is define, though Infrastructure does. Just as a test, I linked to the INavigable source file from indside the Infrastructure project. That allowed me to reference it in that project and compile, but causes havoc in the Book project, because now there's a conflick between the one define in Infrastructure and the one defined in the Web project's web service. This is behavior I would expect. So, to try and sum up a bit. Web project has a web service that process data from a third-party service and has a class and interface defined in it. The class implements the interface. The Infrastructure project references the web service in the Web Project and the Book project references the Infrastructure project. The implmentation of the interface in the class does NOT serialize down, so the auto-genned code in INfrastructure does not show this relationship, breaking code further down-stream. The Book project, whihc is further down-stream CAN see the interface as defined in the Web Project, even though its only reference is through the Infrastructure project; whihc CAN'T see it. Am I simple missing something easy here? Can I apply an attribute to either the Interface definition or to the its implmentation in the class to ensure its visibility downstream? Anything else I can do here? I know this is a bit convoluted and anyone still with me here, thanks for your patience and any advice you might have. Cheers, Steve

• Active Directory: User UPN or DN for NTLM name, using pure LDAP?

  - by Bernd Haug

  I have a Java app that can authenticate to LDAP by logging users into the AD LDAP server with the NTLM name (which they are used to - this is a requirement). I now also need to do authorization, and hence need to find a forest-unique identifier for the user (DN or UPN should work), from which I can further query the directory. The method needs to be absolutely portable, even if the AD is structured in an unusual fashion, otherwise I could just do a string replacement and search for a UPN of "${ntlm-user}@${ntlm-domain}.${configured-trailing-domain}" How can I do this, using pure LDAP? Currently, I'm using the java.naming.directory package, which I'd like to keep using, since it doesn't throw up problems when not binding with a DN but logging in with an NTLM name?

• Create UML diagrams after or before coding?

  - by ajsie

  I can clearly see the benefits of having UML diagrams showing your infrastructure of the application (class names, their members, how they communicate with each other etc). I'm starting a new project right now and have already structured the database (with visual paradigm). I want to use some design patterns to guide me how to code the classes. I wonder, should I code the classes first before I create UML diagram of it (maybe out of the code... seems possible) or should I first create UML diagram and then code (or generate code from the UML, seems possible that too). What are you experiences telling you is the best way?

I am getting an error at the static. GetStockPrices.fs(31,6): error FS0010: Unexpected keyword 'static' in binding. Expected incomplete structured construct at or before this point or other token. Does anyone know if they have changed the syntax or can spot what I am doing wrong

• Best way to provide software settings?

  - by claws

  I'm using C# .NET. In my software I'm providing settings dialog through which user can set the application settings which I want to save to a file. Requirements (typical): Every class I defined uses some part of these settings. So, these should be global to all classes. These should be loaded while software is started. When ever user changes settings and clicks 'save'/'apply'. Current settings should change. I am wondering what is the best way to do this? Also, what is the best way to save these settings to disk? I mean should I create a Settings class object and serializing it to 'settings.dat' or provide an structured file like XML/JSON

• How can I separate Logic/UI in Android

  - by Ungureanu Liviu

  Hi, I want as my application to be structured in 2 parts: the logic code and the UI. I've tried to implement that using a controller class(here I keep the logic code) inside of each activity. The activity send messages to controller and receive the answer in two ways: the answer is returned immediately (if the action is not complex and it can be done in a verry short time) the activity set some listeners and the controller fire this listener when the action is complete. The problems appears when the controller have a lot of objects(each object should handle a set of actions and for each action I have to set & trigger a listener): it is hard to keep the code syncronized. I'm asking if you know a better way to implement this mechanism. Thank you.

• jQuery compatible JavaScript documentation generator

  - by clyfe

  I need to choose a documentation generator (similar to jdoc in java or rdoc in ruby) for my javascript project that (built with jquery, underscore and backbone) Candidates: jsdoc toolkit pdoc natural docs docco YUI doc doctool http://jquery.bassistance.de/docTool/docTool.html other ? Requirements should work with jquery, underscore and backbone. that means object-literal methods etc I really like pdoc but its too centered around prototype, poorly documented, and I don't want to make extra files (sections?) to make it work (not sure about this) docco is nice but I want structured output (as in menu + class/func structure like jdoc) must be command line/makefile compatible (not web pastie) Tips, tricks, tutorials, success stories, advice greatly welcomed. Why Doesn't jQuery use JSDoc?

• Folder cleanup with PowerShell

  - by 280Z28

  I'd like to clean up some directories after my script runs by deleting certain folders and files from the current directory if they exist. Originally, I structured the script like this: if (Test-Path Folder1) { Remove-Item -r Folder1 } if (Test-Path Folder2) { Remove-Item -r Folder2 } if (Test-Path File1) { Remove-Item File1 } Now that I have quite a few items listed in this section, I'd like to clean it up. How can I do so? Side note: The items are cleaned up before the script runs, since they are left over from the previous run in case I need to examine them.

• How important is ticket/bug format?

  - by Fedyashev Nikita

  I've heard many Flame wars about ticket's format: how important is it how it has to be structured what parts has it contain Sometimes, that looks like people want to force other team members to adopt his format, even if it is very similar: steps to reproduce what I see what I have to see explanation Or something like this. Usually they don't offer to change add/delete some section from the ticket, but more like change one's section name, or position. What do you think about it? How to find the best solution(if exists...) and common sense?

• Analysis and Design for Functional Programming

  - by edalorzo

  How do you deal with analysis and design phases when you plan to develop a system using a functional programming language like Haskell? My background is in imperative/object-oriented programming languages, and therefore, I am used to use case analysis and the use of UML to document the design of program. But the thing is that UML is inherently related to the object-oriented way of doing software. And I am intrigued about what would be the best way to develop documentation and define software designs for a system that is going to be developed using functional programming. Would you still use use case analysis or perhaps structured analysis and design instead? How do software architects define the high-level design of the system so that developers follow it? What do you show to you clients or to new developers when you are supposed to present a design of the solution? How do you document a picture of the whole thing without having first to write it all? Is there anything comparable to UML in the functional world?

• Strategy in storing ad-hoc numbers/constants?

  - by Jiho Han

  I have a need to store a number of ad-hoc figures and constants for calculation. These numbers change periodically but they are different type of values. One might be a balance, a money amount, another might be an interest rate, and yet another might be a ratio of some kind. These numbers are then used in a calculation that involve other more structured figures. I'm not certain what the best way to store these in a relational DB is - that's the choice of storage for the app. One way, I've done before, is to create a very generic table that stores the values as text. I might store the data type along with it but the consumer knows what type it is so, in situations I didn't even need to store the data type. This kind of works fine but I am not very fond of the solution. Should I break down each of the numbers into specific categories and create tables that way? For example, create Rates table, and Balances table, etc.?

• How to build a Windows Forms email-aware text box?

  - by Patrick Linskey

  Hi, I'm building a C# client app that allows a user to communicate with one or more existing users in a system via an email-like metaphor. I'd like to present the user with a text entry box that auto-completes on known email addresses, and allows multiple delimiter-separated addresses to be entered. Ideally, I'd also like the email addresses to turn into structured controls once they've been entered and recognized. Basically, I'm modeling the UI interaction for adding users after Facebook's model. Are there any Windows Forms controls out there with the ability to do something like this? Is there any well-established terminology for a hybrid textbox / control list box (no, not a ComboBox) or something that I should be searching for? Thanks, -Patrick

• C# socket blocking behavior

  - by Gearoid Murphy

  My situation is this : I have a C# tcp socket through which I receive structured messages consisting of a 3 byte header and a variable size payload. The tcp data is routed through a network of tunnels and is occasionally susceptible to fragmentation. The solution to this is to perform a blocking read of 3 bytes for the header and a blocking read of N bytes for the variable size payload (the value of N is in the header). The problem I'm experiencing is that occasionally, the blocking receive operation returns a partial packet. That is, it reads a volume of bytes less than the number I explicitly set in the receive call. After some debugging, it appears that the number of bytes it returns is equal to the number of bytes in the Available property of the socket before the receive op. This behavior is contrary to my expectation. If the socket is blocking and I explicitly set the number of bytes to receive, shouldn't the socket block until it recv's those bytes?, any help, pointers, etc would be much appreciated.

• Conversion of DOM element selection code to jQuery

  - by Tom McDonnell

  I have a large Javascript codebase to convert to jQuery. The code is structured such that DOM elements are created in Javascript (using a library called DomBuilder), and saved to variables if they will be needed later, before being added to the DOM. Eg. var inputs = { submitConfirm: INPUT({type: 'button', value: 'Submit'}), submitCancel : INPUT({type: 'button', value: 'Cancel'}) }; document.appendChild(inputs.submitConfirm); Then later for example... inputs.submitCancel.style.display = 'none'; inputs.submitCancel.addEventListener('click', onClickSubmitCancel, false); My problem is that jQuery seems to lack a way of manipulating DOM elements directly, as opposed to selecting them first (with for example $('#submitCancel'). Can anyone suggest a way to directly translate the last two Javascript lines given above to use jQuery, given that the DOM elements are already available, and so do not need to be selected?

• Manual stack backtrace on Windows mobile (SEH)

  - by caahab

  Following situation: I'm developing an windows mobile application using the sdk 6. Target machine is a nautiz x7. To improve the error reporting I want to catch the structured exceptions (SEH) and do a stack backtrace to store some information for analysis. So far I have the information where the exception was thrown (windows core.dll) and I can backtrace the return adresses thru the stack. But what I want to know is, which instruction in my code caused the exception? Does anyone know how to use the available exception and context information to get the appropriate function/instruction address? Unfortunately windows mobile 6 sdk for pocketpc does not support all the helper functions to do stackwalks or mini dumps.

• Copy NSArray and replace text items with bool values

  - by Frank Martin

  I utilize a (nested) plist to populate UITableViews where users can select entries at the deepest levels and set a checkmark (or not). I want to save these selections in a same structured list where at the deepest level the NSArray contains bool values instead the text strings that are displayed in the UITableView. So how can i build from a hierarchy like the following: Root - Item 0 (Dictionary) - Group (Dictionary) - Items (NSArray) - Item 0: @"Please check me" (String) a hierarchy like this? Root - Item 0 (Dictionary) - Group (Dictionary) - Items (NSArray) - Item 0: 0 (NSNumber) // NSNumber for bool values I'm trying to create a deep mutable copy and replace the items at the deepest levels but have somehow the feeling that this can be done easier. Thanks for any help with this in advance. Frank
