• Unleash AutoVue on Your Unmanaged Data

  - by [email protected]

  Over the years, I've spoken to hundreds of customers who use AutoVue to collaborate on their "managed" data stored in content management systems, product lifecycle management systems, etc. via our many integrations. Through these conversations I've also learned a harsh reality - we will never fully move away from unmanaged data (desktops, file servers, emails, etc). If you use AutoVue today you already know that even if your primary use is viewing content stored in a content management system, you can still open files stored locally on your computer. But did you know that AutoVue actually has - built-in - a great solution for viewing, printing and redlining your data stored on file servers? Using the 'Server protocol' you can point AutoVue directly to a top-level location on any networked file server and provide your users with a link or shortcut to access an interface similar to the sample page shown below. Many customers link to pages just like this one from their internal company intranets. Through this webpage, users can easily search and browse through file server data with a 'click-and-view' interface to find the specific image, document, drawing or model they're looking for. Any markups created on a document will be accessible to everyone else viewing that document and of course real-time collaboration is supported as well. Customers on maintenance can consult the AutoVue Admin guide or My Oracle Support Doc ID 753018.1 for an introduction to the server protocol. Contact your local AutoVue Solutions Consultant for help setting up the sample shown above.

• Why should you document code?

  - by Edwin Tripp

  I am a graduate software developer for a financial company that uses an old COBOL-like language/flat-file record storage system. The code is completely undocumented, both code comments and overall system design and there is no help on the web (unused outside the industry). The current developers have been working on the system for between 10 and 30 years and are adamant that documentation is unnecessary as you can just read the code to work out what's going on and that you can't trust comments. Why should such a system be documented?

• What to do when a project is too difficult to continue developing?

  - by MaxWell

  As a developer, can you tell your project manager that an application is unworkable? Or, if you're a project manager, how would you need this presented to you in order to be compelled? This isn't about "how to work on a poor project", it's assuming you cannot. I can provide an example of the situation if anyone thinks it's important, but I'm trying to avoid proposed solutions to "plodding through".

• What issues lead people to use Japanese-specific encodings rather than Unicode?

  - by Nicolas Raoul

  At work I come across a lot of Japanese text files in Shift-JIS and other encodings. It causes many mojibake (unreadable character) problems for all computer users. Unicode was intended to solve this sort of problem by defining a single character set for all languages, and the UTF-8 serialization is recommended for use on the Internet. So why doesn't everybody switch from Japanese-specific encodings to UTF-8? What issues with or disadvantages of UTF-8 are holding people back? EDIT: The W3C lists some known problems with Unicode, could this be a reason too?

• Does your organization still use the term "screens" to describe a user interface?

  - by bit-twiddler

  I have been in the field long enough to remember when the term "screen" entered our lexicon. As difficult as it is to believe, the early systems on which I worked had no user interface (UI), that is, unless one counts a keypunch machine and job listings as a user interface. These systems ran as "card image" production jobs back in a day when being a computer operator required a reasonably deep understanding of how computers worked. Flashing forward to today: I cringe every time I hear a systems practitioner use the term "screen." The metaphor no longer fits the medium. The term somewhat fit back when the user dialog consumed 100% of available monitor real estate; however, the term lost its relevance the moment we moved to windowed environments. With the above said, does your organization still use the term "screens" to describe an application's UI? Has anyone successfully purged the term from an organization? For those who do not use the term to describe UI dialog elements, what term do you use in place of “screen.”

• "Guiding" a Domain Expert to Retire from Programming

  - by James Kolpack

  I've got a friend who does IT at a local non-profit where they're using a custom web application which is no longer supported by the company who built it. (out of business, support was too expensive, I'm not sure...) Development on this app started around 10+ years ago so the technologies being harnessed are pretty out of date now - classic asp using vbscript and SQL Server 2000. The application domain is in the realm of government bookkeeping - so even though the development team is long gone, there are often new requirements of this software. Enter the... The domain expert. This is an middle aged accounting whiz without much (or any?) prior development experience. He studied the pages, code and queries and learned how to ape the style of the original team which, believe me, is mediocre at best. He's very clever and very tenacious but has no experience in software beyond what he's picked up from this app. Otherwise, he's a pleasant guy to talk to and definitely knows his domain. My friend in IT, and probably his superiors in the company, want him out of the code. They view him as wasting his expertise on coding tasks he shouldn't be doing. My friend got me involved with a few small contracts which I handled without much problem - other than somewhat of a communication barrier with the domain expert. He explained the requirements very quickly, assuming prior knowledge of the domain which I do not have. This is partially his normal style, and I think maybe a bit of resentment from my involvement. So, I think he feels like the owner of the code and has entrenched himself in a development position. So... his coding technique. One of his latest endeavors was to make a page that only he could reach (theoretically - the security model for the system is wretched) where he can enter a raw SQL query, run it, and save the query to run again later. A report that I worked on had been originally implemented by him using 6 distinct queries, 3 or 4 temp tables to coordinate the data between the queries, and the final result obtained by importing the data from the final query into Access and doing a pivot and some formatting. It worked - well, some of the results were incorrect - but at what a cost! (I implemented the report in a single query with at least 1/10th the amount of code.) He edits code in notepad. He doesn't seem to know about online reference material for the languages. I recently read an article on Dr. Dobbs titled "What Makes Bad Programmers Different" - and instantly thought of our domain expert. From the article: Their code is large, messy, and bug laden. They have very superficial knowledge of their problem domain and their tools. Their code has a lot of copy/paste and they have very little interest in techniques that reduce it. The fail to account for edge cases, while inefficiently dealing with the general case. They never have time to comment their code or break it into smaller pieces. Empirical evidence plays no little role in their decisions. 5.5 out of 6. My friend is wanting me to argue the case to their management - specifically, I got this email from their manager to respond to: ...Also, I need to talk to you about what effect there is from Domain Expert continuing to make edits to the live environment. If that is a problem for you I need to know so I can have his access blocked. Some examples would help. In my opinion, from a technical standpoint, it's dangerous to have him making changes without any oversight. On the other hand, I'm just doing one-off contracts at this point and don't have much desire to get involved deeply enough that I'm essentially arguing as one of the Bobs from Office Space. I'd like to help my friend out - but I feel like I'm getting in the middle of a political battle. More importantly - if I do get involved and suggest that his editing privileges be removed, it needs to be handled carefully so that doesn't feel belittled. He is beyond a doubt the foremost expert on this system. I'm hoping this is familiar territory for some other stackechangers, because I'm feeling a little bewildered. How should I respond? Should I argue that he shouldn't be allowed to touch the code? Should I phrase it as "no single developer, no matter how experienced, should be working on production code unchecked"? Should I argue to keep him involved with the code, but with a review process? Should I say "glad I could help, but uh, I'm busy now!" Other options? Thanks a bunch!

• How to refactor a myriad of similar classes

  - by TobiMcNamobi

  I'm faced with similar classes A1, A2, ..., A100. Believe it or not but yeah, there are roughly hundred classes that almost look the same. None of these classes are unit tested (of course ;-) ). Each of theses classes is about 50 lines of code which is not too much by itself. Still this is way too much duplicated code. I consider the following options: Writing tests for A1, ..., A100. Then refactor by creating an abstract base class AA. Pro: I'm (near to totally) safe by the tests that nothing goes wrong. Con: Much effort. Duplication of test code. Writing tests for A1, A2. Abstracting the duplicated test code and using the abstraction to create the rest of the tests. Then create AA as in 1. Pro: Less effort than in 1 but maintaining a similar degree of safety. Con: I find generalized test code weird; it often seems ... incoherent (is this the right word?). Normally I prefer specialized test code for specialized classes. But that requires a good design which is my goal of this whole refactoring. Writing AA first, testing it with mock classes. Then inheriting A1, ..., A100 successively. Pro: Fastest way to eliminate duplicates. Con: Most Ax classes look very much the same. But if not, there is the danger of changing the code by inheriting from AA. Other options ... At first I went for 3. because the Ax classes are really very similar to each other. But now I'm a bit unsure if this is the right way (from a unit testing enthusiast's perspective).

• Keep coding the wrong way to remain consistent? [closed]

  - by bwalk2895

  Possible Duplicate: Code maintenance: keeping a bad pattern when extending new code for being consistent, or not? To keep things simple let's say I am responsible for maintaining two applications, AwesomeApp and BadApp (I am responsible for more and no that is not their actual names). AwesomeApp is a greenfield project I have been working on with other members on my team. It was coded using all the fancy buzzwords, Multilayer, SOA, SOLID, TDD, and so on. It represents the direction we want to go as a team. BadApp is a application that has been around for a long time. The architecture suffers from many sins, namely everything is tightly coupled together and it is not uncommon to get a circular dependency error from the compiler, it is almost impossible to unit test, large classes, duplicate code, and so on. We have a plan to rewrite the application following the standards established by AwesomeApp, but that won't happen for a while. I have to go into BadApp and fix a bug, but after spending months coding what I consider correctly, I really don't want do continue perpetuate bad coding practices. However, the way AwesomeApp is coded is vastly different from the way BadApp is coded. I fear implementing the "correct" way would cause confusion for other developers who have to maintain the application. Question: Is it better to keep coding the wrong way to remain consistent with the rest of the code in the application (knowing it will be replaced) or is it better to code the right way with an understanding it could cause confusion because it is so much different? To give you an example. There is a large class (1000+ lines) with several functions. One of the functions is to calculate a date based on an enumerated value. Currently the function handles all the various calculations. The function relies on no other functionality within the class. It is self contained. I want to break the function into smaller functions (at the very least) and put them into their own classes and hide those classes behind an interface (at the most) and use the factory pattern to instantiate the date classes. If I just broke it out into smaller functions within the class it would follow the existing coding standard. The extra steps are to start following some of the SOLID principles.

• How do you deal with the details when reading code?

  - by upton

  After reading some projects, I find that it is not the architecture of the software that is really hard to know. It is not hard to figure out the architecture immediately if the project is clearly designed and implemented, if it's hard and never seen before, some day later I can find out some pattern similar to the one I read in the same domain. The difficulty is that the concepts and mechanism defined by the author are really hard to guess, and these concepts may spread in the whole project which makes it hard to grasp. The situation is normal and universal and you can ask questions to your colleague when in a company. However, it gets worse if nobody around you knows these details. How do you handle these details which block your reading?

• How to cope with "Hidden IT..." Who writes and maintains the ad-hoc software applications?

  - by matcauthon

  Bigger companies usually have the problem, that it is not possible to write all programs employees want (to save time and to optimize processes) due to a lack of staff and money. Then hidden programs will be created by some people having (at least some) coding experience (or by cheap students/interns...). Under some circumstances these applications will raise in importance and spread from one user to a whole department. Then there is the critical point: Who will maintain the application, add new features, ...? And this app is critical. It IS needed. But the intern has left the company. No one knows how it works. You only have a bunch of sources and some sort of documentation. How do you cope with these applications? Can you "forbid" them? Can you control them? Do you have to write all apps (not Excel macros or some minor stuff) in the IT department?

• Forbidding or controlling "Hidden IT..." Who should write and maintain ad-hoc software applications?

• Add Zend_Navigation to the View with old legacy bootstrap

  - by Grant Collins

  Hi, I've been struggling with Zend_Navigation all weekend, and now I have another problem, which I believe has been the cause of a lot of my issues. I am trying to add Zend_Navigation to a legacy 1.7.6 Zend Framework application, i've updated the Zend Library to 1.9.0 and updated the bootstrap to allow this library update. The problem is that I don't know how, and the examples show the new bootstrap method of how to add the Navigation object to the view, I've tried this: //initialise the application layouts with the MVC helpers $layout = Zend_Layout::startMvc(array('layoutPath' => '../application/layouts')); $view = $layout->getView(); $configNav = new Zend_Config_Xml('../application/config/navigation.xml', 'navigation'); $navigation = new Zend_Navigation($configNav); $view->navigation($navigation); $viewRenderer = new Zend_Controller_Action_Helper_ViewRenderer(); $viewRenderer->setView($view); This seems to run through fine, but when I go to use the breadcrumb view helper in my layout, it errors with: Strict Standards: Creating default object from empty value in C:\www\moobia\development\website\application\modules\employers\controllers\IndexController.php on line 27 This is caused by the following code in the init() function of my controller. $uri = $this->_request->getPathInfo(); $activeNav = $this->view->navigation()->findByUri($uri); <- this is null when called $activeNav->active = true; I believe it's because the Zend_Navigation object is not in the view. I would look at migrating the bootstrap to the current method, but at present I am running out of time for a release. Thanks, Grant

• Integrating legacy Ajax script in CakePHP

  - by octavian

  Hi, I have a legacy script that I would like to integrate in a cakephp app. The script makes use of $_POST and such and since I'm quite a noob I would need some help for the integration. Here is how the script looks like: THE JAVASCRIPT: prototype.js builder.js (these two are from the prototype fw) lib.js (makes a ajax requests to remote.php) THE PHP remote.php (contains FastJSON class and $_POST vars) if ($_POST['cmd'] == 'SAVETEAM' && $_POST['info']) { $INFO = json_decode(str_replace('\"', '"', $_POST['info'])); $nr = 1; $SORT = array($INFO->GK, $INFO->DEF, $INFO->MID, $INFO->FOR, $INFO->RZ); foreach ($SORT as $STD) foreach ($STD as $v) mysql_query("UPDATE players_teams SET fieldposition = ".$nr++." WHERE player_id = {$v->player_id} AND team_id = {$v->team_id}") or die(mysql_error()); // CAPTAION mysql_query("UPDATE `teams` SET captain = '{$_POST['captain']}' WHERE `user_id` = {$_POST['userid']}") or die(mysql_error()); } transfers.php (containts the form that uses the javascript and link to the JS) I have really no idea how to structure the files and calls in cakephp. Currently I have "Undefined index: cmd [APP/vendors/remote.php, line 230]" errors since I use $_POST['cmd'] (I placed remote.php in Vendors and included it, the JS was just included old fashion way, as a link and appears in the source code). How can I make this work? I'm sorry but I'm not familiar with AJAX and Cake... If you want a full look at the code, here it is: http://octavian.be/thecode.zip Thank you for reading and helping me out.

• NHibernate, legacy database, foreign keys that aren't

  - by Joe

  The project I'm working on has a legacy database with lots of information in it that's used to alter application behavior. Basically I'm stuck with something that I have to be super careful about changing. Onto my problem. In this database is a table and in this table is a column. This column contains integers and most of the pre-existing data have a value of zero for this column. The problem is that this column is in fact a foreign key reference to another entity, it was just never defined as such in the database schema. Now in my new code I defined my Fluent-NHibernate mapping to treat this column as a Reference so that I don't have to deal with entity id's directly in my code. This works fine until I come across an entity that has a value of 0 in this column. NHibernate thinks that a value of 0 is a valid reference. When my code tries to use that referenced object I get an ObjectNotFoundException as obviously there is no object in my database with an id of 0. How can I, either through mapping or some kind of convention (I'm using Fluent-nhibernate), get NHibernate to treat id's that are 0 the same as if it was NULL?

• Non-normalized association with legacy tables in Rails and ActiveRecord

  - by Thomas Holmström

  I am building a Rails application accessing a legacy system. The data model contains Customers which can have one or more Subscriptions. A Subscription always belong to one and only one Customer. Though not needed, this association is represented through a join table "subscribes", which do not have an id column: Column | Type | Modifiers -----------------+---------+----------- customer_id | integer | not null subscription_id | integer | not null I have this coded as a has_and_belongs_to_many declarations in both Customer and Subscription class Customer < Activerecord::Base has_and_belongs_to_many :subscriptions, :join_table => "subscribes", :foreign_key => "customer_id", :association_foreign_key => "subscription_id" end class Subscription < Activerecord::Base has_and_belongs_to_many :customers, :join_table => "subscribes", :foreign_key => "subscription_id", :association_foreign_key => "customer_id" end The problem I have is that there can only ever be one customer for each subscription, not many, and the join table will always contain at most one row with a certain customer_id. And thus, I don't want the association "customers" on a Subscription which returns an array of (at most one) Customer, I really do want the relation "customer" which returns the Customer associated. Is there any way to force ActiveRecord to make this a 1-to-N relation even though the join table itself seems to make it an N-to-M relation? --Thomas

• Legacy application creates dialogs in non-ui thread.

  - by Frater

  I've been working support for a while on a legacy application and I've noticed a bit of a problem. The system is an incredibly complex client/server with standard and custom frameworks. One of the custom frameworks built into the application involves validating workflow actions. It finds potential errors, separates them into warnings and errors, and passes the results back to the client. The main difference between warnings and errors is that warnings ask the user if they wish to ignore the error. The issue I have is that the dialog for this prompt is created on a non-ui thread, and thus we get cross-threading issues when the dialog is shown. I have attempted to invoke the showing of the dialog, however this fails because the window handle has not been created. (InvokeRequired returns false, which I assume in this case means it cannot find a decent handle in its parent tree, rather than that it doesn't require it.) Does anyone have any suggestions for how I can create this dialog and get the UI thread to set it up and call it?

• Safari specific scroll bar issue in legacy code

  - by user1237169

  I am trying to debug an issue that is occurring specifically in Safari. On a few pages of a web application, the content is larger than the frame and a scroll bar appears on the right but when the scroll bar moves up or down the content does not scroll with it. So you can "scroll" the scroll bar but the content itself was inaccessible even though the scroll bar was mobile. The issue only occurs in the "Multi-Process Windows" debug mode option but not in the "Single-Process Windows" option. The scroll bar works perfectly fine in Firefox, IE, and Chrome, just not in Safari. Because there's a lot of legacy code, I'm not quite sure exactly what the actual content is and which specific html elements are relevant. From what I can tell there's an Iframe element, html element, body element, div element, iframe element html element, body element and finally some divs. edit Does it matter if some of the elements within the <iframe> have the attribute scrolling="no"? I see this on a few of the elements within iframe but my coworker reassures me they don't matter.

• Ruby on Rails login using legacy user database

  - by ricsmania

  Hello, I have a Rails application that connects to a legacy database (Oracle) and displays some information from a particular user. Right now the user is passed as a URL parameter, but this has obvious security issues because users should only be able to see their own data. To solve that, I want to implement a user login, and I did some research and came across 2 components for that, restful_authentication and authlogic. The problem is that I need to use an existing user/password database instead of creating a new one, which is the common way to use those components. The password is encrypted by a custom Oracle package, but let's assume it is stored as plain text to make things simpler. I only need very basic functionality, which is login a user and keep them logged in forever until logout. No changes to the database will be made by this application, so there's no need for sign up, e-mail activation, reset password, etc. Can someone point me in the right direction on how to do that? Is any of those 2 components a good solution? If not, what would be recommended? Thanks!

• rake db:create not working for legacy rails app (2.3.5) using MySQL (5.5.28)

  - by ridicter

  I'm a new Rails Developer, and I'm working on a legacy Rails app. Whenever I run the rake db:create command, I get an error that the database couldn't be created. I have found many StackOverflow questions related to this, but in troubleshooting nearly all permutations of solutions, I couldn't resolve the issue. I created the three Dbs (dev, prod, test), created the user with all access privileges to these dbs, and ran rake db:create. I'm running Mac OS X Lion, MySQL 5.5.28, Rails 2.3.5, Ruby 1.8.7. Here are my settings development: adapter: mysql encoding: utf8 database: adva_development username: adva password: **** host: localhost socket: /tmp/mysql.sock Here's the error: Couldn't create database for {"adapter"=>"mysql", "username"=>"adva", "host"=>"localhost", "encoding"=>"utf8", "database"=>"adva_development", "socket"=>"/tmp/mysql.sock", "password"=>"****"}, charset: utf8, collation: utf8_unicode_ci (if you set the charset manually, make sure you have a matching collation) I have done the following troubleshooting: Verified user and password are correct, and the user has access to the DB. (Double checked user access with SELECT * FROM mysql.db WHERE Db = 'adva_development' \G; User has all privileges.) Verify the socket is correct. I don't really understand sockets, but I can plainly see it at /tmp/mysql.sock. Checked collation and character set. I found out I had created the DB in latin charset and collation, so I recreated them. I ran show variables like "collation_database"; and show variables like "character_set_database"; and came back with utf8 and utf8_unicode_ci respectively. I followed the instructions in this question. After uninstalling mysql gem, I ran the following but came up with the same error: gem install --no-rdoc --no-ri mysql -- --with-mysql-dir=/usr/local/mysql-5.5.28-osx10.6-x86_64/bin --with-mysql-config=/usr/local/mysql-5.5.28-osx10.6-x86_64/bin/mysql_config Following Matt's suggestion, here's what a rake --trace db:create reveals: ** Invoke db:create (first_time) ** Invoke db:load_config (first_time) ** Invoke rails_env (first_time) ** Execute rails_env ** Execute db:load_config ** Execute db:create Couldn't create database for {"database"=>"adva_development", "adapter"=>"mysql", "host"=>"127.0.0.1", "password"=>"woof2adva", "username"=>"adva", "encoding"=>"utf8"}, charset: utf8, collation: utf8_unicode_ci (if you set the charset manually, make sure you have a matching collation) After 3 days and six or seven hours, I have pretty much run out of options. I tried various random things, like replacing localhost with 127.0.0.1 to no avail. Could there be something wrong related to my specific environment? Mac OS X Lion + MySQL 5.5.28? I plan on trying on setting up everything in a Linux environment. Thanks!

• Debian on Hyper-V

  - by Tobia

  I installed Debian with kernel 2.6.32-5-686 on a Hyper-V virtual machine. I had to add a legacy network card. I follow this tutorial http://www.microsofttranslator.com/bv.aspx?ref=Internal&from=ru&to=en&a=http://blogs.technet.com/b/abeshkov/archive/2011/03/17/hyperv_5f00_debian.aspx to add Hyper-V driver but when I reboot with the new kernel it crash during bootup. Is there any other way to load hyper-v drivers? I really need to change that legacy network card because my debian machine is going to be used as proxy. Thank you.

• Networking Problem MrxSmb event 50 "Delayed Write Failed" errors occurring all of the sudden

  - by Johnny Musso

  JUST THIS MONTH, we have started getting reports from a number of very stable clients that MrxSmb event id 50 errors keep appearing in their system event logs. Otherwise, they do not appear to have any networking problems except that there is a critical legacy application which seems to either be generating the MrxSmb errors or having errors occur because of them. The legacy application is comprised of 16 bit and 32 bit code and has not been changed or recompiled in many years. It has always been stable on Windows XP systems. The customers that have the problem usually have a small (5 clients or less) peer to peer network with all Windows XP systems. All service packs are loaded on the XP machines. Note: The only thing that seems to correct the problem is disabling opportunistic locking. I don't like this solution because it seems to slow down the network and sometimes causes record locking issues between users (on some networks). Also, this seems to have just started happening - as if a Windows update for XP has caused it? However, I have removed recent updates and it did not correct the issue. Thanks in advance for any help you can provide.

• Compiling a program with a legacy version of gcc

  - by wyatt

  This is probably a very difficult problem to troubleshoot with the information I can practically provide, but I'm hoping someone might be able to at least point me in a possible direction. I'm trying to install HTK (http://htk.eng.cam.ac.uk/), which, according to this page needs to be installed using gcc 3.4. Their method of implementing backwards compatibility: #yum install compat-gcc-34-c++ compat-gcc-34 won't work for me as I'm running Ubuntu (On that note, I take it I can't simply install YUM and the subsequent package, since it's an entirely different distro, but if I'm wrong I'd love to hear it). I instead installed two versions of gcc 3.4 - 3.4.0 and 3.4.6 using instructions from this site. I then added the lines suggested by that page to the top of the makefile (on this note, what's the difference between makefile and makefile.in?

• Legacy application with JDBC and JNDI REALM authentication

  - by KB

  Hello All, My application currently relies on JDBC realm authentication. Recent needs have forced us to think about having LDAP authentication as well. We are thinking about using Active Directory for both authentication as well as authorization (roles). As a standalone test, I was able to authenticate my application with AD. But here is the confusion I have going forward. If the user chooses LDAP authentication when he logs in, I authenticate the user with AD, get the user's roles and do I replicate(create a new) windows user in my database?. I have to have the user in the database, because many parts of the application is designed to retrieve the user from database If the users chooses local login, I still should have JDBCRealm somewhere that I should use to authenticate the user. Is it possible to have multiple realms in tomcat? (I sort of know it is possible, but havent seen much documentation around it) Any thoughts, comments, suggestions would immensely help me Thanks K

• Experience migrating legacy Cobol/PL1 to Java

  - by MadMurf

  ORIGINAL Q: I'm wondering if anyone has had experience of migrating a large Cobol/PL1 codebase to Java? How automated was the process and how maintainable was the output? How did the move from transactional to OO work out? Any lessons learned along the way or resources/white papers that may be of benefit would be appreciated. EDIT 7/7: Certainly the NACA approach is interesting, the ability to continue making your BAU changes to the COBOL code right up to the point of releasing the JAVA version has merit for any organization. The argument for procedural Java in the same layout as the COBOL to give the coders a sense of comfort while familiarizing with the Java language is a valid argument for a large organisation with a large code base. As @Didier points out the $3mil annual saving gives scope for generous padding on any BAU changes going forward to refactor the code on an ongoing basis. As he puts it if you care about your people you find a way to keep them happy while gradually challenging them. The problem as I see it with the suggestion from @duffymo to Best to try and really understand the problem at its roots and re-express it as an object-oriented system is that if you have any BAU changes ongoing then during the LONG project lifetime of coding your new OO system you end up coding & testing changes on the double. That is a major benefit of the NACA approach. I've had some experience of migrating Client-Server applications to a web implementation and this was one of the major issues we encountered, constantly shifting requirements due to BAU changes. It made PM & scheduling a real challenge. Thanks to @hhafez who's experience is nicely put as "similar but slightly different" and has had a reasonably satisfactory experience of an automatic code migration from Ada to Java. Thanks @Didier for contributing, I'm still studying your approach and if I have any Q's I'll drop you a line.

• Registration-Free .net libraries with legacy VB6 applications

  - by Vidar

  I've been searching for hours for resources on how to successfully use registration free Com interop. I've found some resources on using old COM libraries in .net applications, but allmost nothing on using new .NET libraries in COM applications (more spcecific: VB6 applications) Basically my search gave two useful resources: http://msdn.microsoft.com/en-us/library/ms973915.aspx (Walkthrough by Steve Wight) There is allso the main MSDN article on the subject (No link because this is my first post, and I am only allowed one link) Is nobody else doing this, or am I the only one struggling to get my head around it? Any good reads will be very much appreciated
