• Possible to get the line number of the currently executing sproc in SQL Server?

  - by Ian Kemp

  A few years back I worked in a Sybase/Delphi environment, using the BDE to connect to the DB server. We had a little Delphi app that, given the name of a currently executing stored procedure, could tell you what line of that sproc was currently being executed. This was exceptionally useful for debugging sprocs that seemed to be hanging. I'd like to use this functionality in SQL Server, but I can't remember whether it was a Sybase or a BDE feature. Is this functionality available in SQL Server and if so, what command(s) do I need to use to view this information?

• How to manage Libraries/jar files in eclipse?

  - by pvsnp

  I might be missing something but how do you manage Java projects in eclipse that need a lot of Jar files. I know maven manages libraries well if there are new updates but maybe I'm missing something, is there a way that eclipse can update new jar files (it would be especially useful for projects using apache-commons, say). I don't want to sound like asking for a feature request, but I'm looking at if there are ways to keep libraries jar files that a Java project uses to keep them updated automatically the way maven does. With more languages coming with this type of features, finding the right Jar files probably should be easier than this.

• DAO design pattern and using it across multiple tables

  - by Casey

  I'm looking for feedback on the Data Access Object design pattern and using it when you have to access data across multiple tables. It seems like that pattern, which has a DAO for each table along with a Data Transfer Object (DTO) that represents a single row, isn't too useful for when dealing with data from multiple tables. I was thinking about creating a composite DAO and corresponding DTO that would return the result of, let's say performing a join on two tables. This way I can use SQL to grab all the data instead of first grabbing data from one using one DAO and than the second table using the second DAO, and than composing them together in Java. Is there a better solution? And no, I'm not able to move to Hibernate or another ORM tool at the moment. Just straight JDBC for this project.

• Linux application that bundles multiple incoming audio and video streams into one container file?

  - by StackedCrooked

  I've been assigned to implement a video on-demand service for a local university. Different aspects of the lectures (video, audio, screen cast, white board) will be recorded. During a lecture all these data streams arrive at one Linux server. This server should transcode and bundle all these streams into one container (Matroska) file. My options seem to be: Write a GStreamer application do something with FFMPEG do something with VLC ...? Has anyone done something similar in the past? Can you recommend something? Edit For those interested, here are a few of my findings: Matroska is not a good format for streaming (it's possible, but it's not its primary intent) For Flash streaming you can use MPEG4 If you want to combine different videos into one video where each subvideo occupies a rectangular portion of the total screen, then this GStreamer script is useful (I found it on this blog post). Desktop capture works fine with VLC

• Documenting and defining content types for a CMS or similar project

  - by Rimian

  I'm writing up some documentation on a Drupal project and my task is to define the content types and their attributes. The intended audience is project managers and developers. So it could be a high level document that gives an overview of the system. (I think that's how I describe it: high level rather than high detail) At the moment I'm using open office and bullet points but it seems like an amateurish method when I need to describe details that could be useful for a developer (me). Something like UML would describe detail but is probably more complicated than I need right now and could be too technical for others on the team. Are there any universal methods or templates that I can use to describe information in this case?

• Some good websites to learn about JavaScript and programming architecture?

  - by Jack Roscoe

  I'm not sure if 'architecture' is the correct term, but I've been looking for some articles online which talk about programming design and more about how best to use languages such as JavaScript in a code design sense rather than the actual syntax itself. I have found many websites but a lot seem to be very out dated, and I'm not sure what developments have taken place with JavaScript over the years so do not know how old is too old. If anybody could suggest some great websites, or maybe specific articles you think would be useful, that would be highly appreciated. I am a beginner programmer currently using JavaScript with XML and of course HTML & CSS, and I'm currently trying to get further into and learn more about web development.

• Designing a frontend/backend architecture

  - by wrp

  What are some good information sources on designing programs with a client/server architecture? This is for development of a desktop application, not a Web service. The only books I have found on client/server apps deal with the case of a thin client connecting to a remote database. Two good examples of what I mean are Mathematica and SuperCollider. I'm looking for platform- and language-agnostic discussion of the issues in developing a frontend/backend system. Especially useful topics would be allocation of responsibilities and options for message passing.

• When is it appropriate to use C++ exceptions?

  - by krebstar

  I'm trying to design a class that needs to dynamically allocate some memory.. I had planned to allocate the memory it needs during construction, but how do I handle failed memory allocations? Should I throw an exception? I read somewhere that exceptions should only be used for "exceptional" cases, and running out of memory doesn't seem like an exceptional case to me.. Should I allocate memory in a separate initialization routine instead and check for failures and then destroy the class instance gracefully? Or should I use exceptions instead? The class won't have anything useful to do if these memory allocations should fail.. EDIT: The consensus seems to be that running out of memory IS an exceptional case. Will see how to go about this.. Thanks.. :)

• Error in my OO Generics design. How do I workaround it?

  - by John

  I get "E2511 Type parameter 'T' must be a class type" on the third class. type TSomeClass=class end; ParentParentClass<T>=class end; ParentClass<T: class> = class(ParentParentClass<T>) end; ChildClass<T: TSomeClass> = class(ParentClass<T>) end; I'm trying to write a lite Generic Array wrapper for any data type(ParentParentClass) ,but because I'm unable to free type idenitifiers( if T is TObject then Tobject(T).Free) , I created the second class, which is useful for class types, so I can free the objects. The third class is where I use my wrapper, but the compiler throws that error. How do I make it compile?

• Feature categories for a social network

  - by mafutrct

  Not sure if this question belongs on SO. Anyway, please let me try to clarify the issue. I'm currently planning a social program. It's basically a chat server with the major additional ability to play games. I'd like to create categories of features that are offered to users. My question is, are there any useful standard feature categories? Does not have to be specific to my case, I'm interested in the general case as well. Just to give you an idea of what I'm thinking: functional e.g. play games social e.g. chatting operational e.g. 24/7 service availability I'm entirely unsure if this is the right place to ask, if you know of any better site to ask please don't hesitate to add a comment.

• I would like to useJava 7's FileVisitor to walk up a tree

  - by John Ormerod

  I have looked and searched for some guidance on how to start at a low point in a path and walk up (or 'back'), until I find a folder with the name I am searching for. The FileVisitor class looks like it ought to be able to help me, but it only seems to work from head to toe. Is there something that someone could point me to? Thanks, John {edited: I seem to be discouraged from saying thanks to the two people who replied in a comment. So thanks! I had a 'duh!' moment when I saw the simple approach. And the article looks useful to someone starting to use FileVisitor. Put them together, and I could go up and then down, if I needed to. John]

• How to pay your users? (alternatives to PayPal)

  - by Sosh

  Hi, I would like to know what best non-paypal options are for paying users of your website (for services rendered for instance). How are others doing this at the moment? If you could mention specific services providers that would be most useful. This would have to work internationally, not be limited to one country. Thank you Update (in response to comments) Reason for excluding PayPal: I've had bad experiences with them in the past. Amounts: Well, i don't mean micropayments of a few cents, but could be anything from 40EUR - 500 EUR. Currency: I didn't mention this, but I would be paying in Euros.

• Simple Java question

  - by user322102

  Hi All I new to java so bare with me if this is a ridiculously simple question but I am curious about this method call which has {code} being taken in - see code below for an example in the method addSelectionListener. What is the purpose of this? I have been looking through docs for an explaination but cant seem to find what this practice is called never mind any useful information. setStatusLine.addSelectionListener(new SelectionAdapter() { public void widgetSelected(SelectionEvent e) { String message = "I would like to say hello to you."; if (pressed) { message = "Thank you for using me"; } setStatusLine(message); pressed = !pressed; } }); Thanks for any help or insights that can be offered

• What tools do you use when generating markup from mockups?

  - by Paul

  So I endeavor to spend most of time on the app server side of things but time to time I need to get my hands dirty and generate markup/css/js from a wireframe or mockup. As far as tools go, Ive found browsershots and Litmus app helpful and of course, vm's as well for checking things out live in ie-{6,7,8}. Otherwise I do the heavy lifting in vim. For generating new markup thats not tied to a target design I think some of the css frameworks & tools like sass look useful but Im skeptical of their utility when needing to generate markup to match a photoshop design. So what tips / tools do you keep in your markup generating utility belt when building solid markup from designs? My list so far: Browsershots Browserlab.adobe.com Haml / Less / Sass (not used but will probably explore)

• Good way to "wrap" jars for OSGi with Maven

  - by javamonkey79

  I was looking at the PAX tools on OPS4J for example: this one and I thought I'd found a nice way to: Specify an artifact Create an assembled jar (jar that contains all dependencies) from that jar and it's transitive dependencies Wrap it with BND to create an OSGi bundle It turns out, that I was wrong - it doesn't appear that the PAX stuff does this. (RTFM, right? :) ) But this got me wondering: is there something out there that does what I'm asking? I've thought maybe I could do this by creating a simple POM and using the maven-bundle-plugin but this seems like it might be a bit cumbersome for what I'm asking. NOTE: I get that embedding and assembling jar's is not really "the OSGi way" - so I wouldn't do this unless I really felt it useful. For example - Spring. Thanks in advance.

• Bound a treeview control to user-defined complex type using EF 4

  - by GIbboK

  Hi, I use Asp.net, SQL 2008 and EF 4. I need display hierarchy data in a treeview control, Data is stored in a DB that use HierarchyId. Unfortunately, EF4 doesn't support HierarchyId. So in this case, I thought to have a stored procedure that deals with my hierarchy and return a result set back to EF that EF4 can turn into a collection of user-defined complex type that can then be bound directly to the treeview control. I imported a SPROC in EF 4 using Import Function and now I have a Complex DataType called: CategoryHierarchy_Result An image of my Model: Here some data from the Complex Type (in a GridView for example GridView1.DataSource = context.CategoryHierarchy(1);): My questions is: How to display my data from my Complex Type in a TreeView Control, showing a Tree structure that respect CategoryNodeString? I am a beginner an I never use TreeView before, any help or resource would be appreciated! Thanks!. Here some useful resource: http://www.robbagby.com/entity-framework/entity-framework-modeling-action-stored-procedures/

• Any open source hosting site for abandoned projects?

  - by ssg

  I have some projects which I have ceased their development a long time ago but still get code access requests for. I'm currently providing zipped packages from my personal web site. I think zipped packages are far from being useful (e.g. can't read code right away, can't provide url's to individual source files, can't fork easily, lifetime is dependent on my own web page's). I want that archaic code to be present on the net regardless I keep my web page up or not. I saw the question "What's the best open source hosting site?". However, most sites request the project "to be active", Codeplex for instance. I didn't go through EULA's of all providers to see if they allow abandoned projects. Are there elephant's graveyards for old code without activity restrictions? Which one would you pick, why?

• Alternate User select interface in django admin to reduce page size on large site?

  - by David Eyk

  I have a Django-based site with roughly 300,000 User objects. Admin pages for objects with a ForeignKey field to User take a very long time to load as the resulting form is about 6MB in size. Of course, the resulting dropdown isn't particularly useful, either. Are there any off-the-shelf replacements for handling this case? I've been googling for a snippet or a blog entry, but haven't found anything yet. I'd like to have a smaller download size and a more usable interface.

• Most valued skill set in web development industry/what should I be doing now? (Kinda random "career"

  - by Andrew

  I want to be a web programmer [when I grow up?] because it's what I like doing, and I really do thoroughly enjoy it (web development in general, actually). I have about 2 years experience with PHP, CSS, and HTML and a few months experiance with JS and jQuery. I've been wondering this for a while -- what languages should I be most familiar with if I want to try and make a career out of web development? I'm only 17, so I've got plenty of time, and I think I've got a decent headstart on things, but it doesn't hurt to ask. If I'm thinking in terms of being able to get hired as a web programmer, what is (or what are...?) the most useful thing I can do now to be able to have an upper hand when it comes to looking for a job. What languages, as a young programmer, should I really focus on? If you were looking to hire a developer, what would you be looking for?

• Listing like appstore in firefox or any other browser for windows/desktop linux

  - by jenso

  A little question about the listing in iPhone OS and some other applications, and possibly in Android Market. When listing the apps, it fills the list in an automatic process, when reaching or is near to reach the end. My question is: How is that written in iPhone applications. But the main question is: Is that possible to make for Firefox users with Javascript, Ajax or possibly any other language? Been looking a little bit in documentation but havent found anything useful, maybe I just havent looked enough edit: Found it for Android - http://stackoverflow.com/questions/1917773/dynamic-listview-in-android-app Still looking for same futures for a Windows browser tho out

• C#: When should I use TryParse?

  - by zxcvbnm

  I understand it doesn't throw an Exception and because of that it might be sightly faster, but also, you're most likely using it to convert input to data you can use, so I don't think it's used so often to make that much of difference in terms of performance. Anyway, the examples I saw are all along the lines of an if/else block with TryParse, the else returning an error message. And to me, that's basically the same thing as using a try/catch block with the catch returning an error message. So, am I missing something? Is there a situation when this is actually useful?

• Where can I find a proper JavaScript beautifier

  - by Ernelli

  I have used http://jsbeautifier.org/ successfully using Rhino and ant, but the problem is that it is not deterministic. If you run the beautifier twice on a file the result is different from each time, e.g. each pass inserts additional array intendation on some lines. I have spent a lot of time debugging the code in beautify.js and have made some workarounds for comment handling, but the array indentation bug is annoying. Is there a correct and properly working JS code formatter anywhere that can be used as part of a source code indentation verification system? EDIT I have now tested with preserve-array-formating disabled, and it seems that it solves the problem. Too bad, since preserve-array-formating is quite useful with large array constructs.

• What to Learn: Rails 1.2.4 -> Rails 3

  - by Saterus

  I've recently convinced my management that our outdated version of Rails is slowing us down enough to warrant an upgrade. The approach we're taking is to start a fresh project with current technology rather than a painful upgrade. Our requirements for the project have changed and this will be much easier. The biggest problem is actually that my knowledge of Rails is out of date. I've dealt only with Rails 1.2.4 while the rest of the world has moved on long ago. What topics have I missed by being buried in my work instead of keeping up with the current Rails fashion? I'm hesitant to dig through blogs at random because I'm not sure how much has changed between the intervening versions of Rails. It's no use to learn Rails 2.1-2.3 specific stuff that is no longer useful for Rails 3.

• [PHP] using the magic __set() method with 2D arrays

  - by Spoonface

  If I have the following registry class: Class registry { private $_vars; public function __construct() { $this->_vars = array(); } public function __set($key, $val) { $this->_vars[$key] = $val; } public function __get($key) { if (isset($this->_vars[$key])) return $this->_vars[$key]; } public function printAll() { print "<pre>".print_r($this->_vars,true)."</pre>"; } } $reg = new registry(); $reg->arr = array(1,2,3); $reg->arr = array_merge($reg->arr,array(4)); $reg->printAll(); Would there be an easier way to push a new item onto the 'arr' array? This code: 'array[] = item' doesn't work with the magic set method, and I couldn't find any useful info with google. Thanks for your time!

• how to deal with a static analyzer output

  - by Jim

  We have started using a static analyzer (Coverity) on our code base. We were promptly stupefied by the sheer amount of warnings we received (its in the hundreds of thousands) , it will take the entire team a few mounts to clear them all (obliviously impossible). the options we discussed so far are 1) hire a contractor to sort out the warning and fix them - he drawback: we will probably need very experiences people to do all these modifications, and no contractor will have required understanding of the code. 2) filter out the warning and deal only with the dangerous ones - the problem here is that our static analysis output will always be cluttered by warning making it difficult for us to isolate problems. also the filtering of the warning is also a major effort. either way, bringing our code to a state when the static analyzer can be a useful tool for us seems a monumental task. so how is it possible to work with the static analyzer without braining current development efforts into a complete stand still?
