• Crystal Reports not included in Visual Studio 2010 – What are the consequences for the introduction

  - by Dirk

  Yesterday I stumbled over the information that Crystal Reports will no longer be included in Visual Studio 2010. Instead – it will be provided as a free download, but with a separate installation and a separate release date. According to the linked information the release of CR will be later than that of VS. My projects depend in parts on CR and I want to shift early to VS 2010. So there are some related questions: Can I use VS 2010 with the older 2008 version of CR? Do I need a workstation with a preinstalled VS 2008 or is the installation of the CR redistribution package sufficient to run that? Are there any experiences with the VS Beta concerning that?

• XMLHttpRequest progressive download?

  - by StackedCrooked

  Just for fun I was creating a JavaScript console for controlling my PC. It involves a small webserver that takes command strings and forwards those to the system using popen calls (to be more specific popen4 on a Ruby mongrel server). The stdout channels are redirected to the http response. The problem is that the response only arrives once the entire contents of stdout has been sent. This is ok for small commands, but not for a command like find / which lists all the files in the system. In such situations it would be nice to have the results shown progressively in the webview (just like in the regular terminal). I thought that using XMLHttpRequest synchronously might result in progressive downloading, but it doesn't seem so. Is there any way to make it work?

• WordPress > microsites use main site's menu (same domain, multiple subdirectories, multiple WP insta

  - by Scott B

  I have a main site at site.com and several subdirectory "microsites" at site1.site.com, site2.site.com, etc. These are all on the same server. Each site is set up in its own folder under public_html and each with its own separate wordpress install. I'd like for each microsite to share the same top level menu (the page's menu) with the main site. I'm sure there are several approaches and I'd like to ask you for a few ideas. As an aside, I'd also like to ask if the new WordPress 3.0 beta would make this simpler to do (since it combines wordpress MU into the main wordpress core)

• Function return type style

  - by JB

  I'm learning c++0x, at least the parts supported by the Visual C++ Express 2010 Beta. This is a question about style rather than how it works. Perhaps it's too early for style and good practice to have evolved yet for a standard that isn't even released yet... In c++0x you can define the return type of a method using - type at the end of the function instead of putting the type at the start. I believe this change in syntax is required due to lambdas and some use cases of the new decltype keyword, but you can use it anywhere as far as I know. // Old style int add1(int a, int b) { return a + b; } // New style return type auto add2(int a, int b) -> int { return a + b; } My question really then, is given that some functions will need to be defined in the new way is it considered good style to define all functions in this way for consistency? Or should I stick to only using it when necessary?

• Java Or C++ Or What???

  - by Kronass

  Hi, My friends and I are starting a new project and we are shifting from windows to linux (for some reasons) and all of us are .Net background. for the new platform I decided to go with Java since many parts are similar with .Net but my friend is insisting on C++ saying it is much faster very mature and working with it will not effect on the productivity and development speed. The project that we will work on it will have threading, extensive string and datetime manipulation, some socket programing and of-course work with RDBMS (MySql Or Postgre not decided yet). I have some fears with java since oracle acquired sun and these people will do anything to make money out of it. some have advised in python and ruby and I like python but don't know should I make it the default language in this project. the project is not web application and we will make services and executables. what do you think, if you have other opinion you very welcome. Hint: Mono is not an option

• Are tags considered requirements? [closed]

  - by krunk

  I'm new to stack overflow, made a few responses. I responded to a question that was something like: "I need to do X, I found a sed one liner that almost does it, but not quite" And was tagged 'sed'. I assumed the user just wanted a solution and tagged it with sed because it was a possible answer. So I suggested an alternate way using another tool that was more concise and didn't involve regex (another one-liner). I received a down vote for not meeting the requirement of the user. Since I'd like to make sure I conform to good forum etiquette, my question is: Are tags considered hard requirements that should limit the scope of responses? (within reason of course, a .NET question with a .NET tag obviously shouldn't receive a ruby answer).

• Is there a better way to minimize this C# event repetition?

  - by Damien Wildfire

  I have a lot of code like this: public class Microwave { private EventHandler<EventArgs> _doorClosed; public event EventHandler<EventArgs> DoorClosed { add { lock (this) _doorClosed += value; } remove { lock (this) _doorClosed -= value; } } private EventHandler<EventArgs> _lightbulbOn; public event EventHandler<EventArgs> LightbulbOn { add { lock (this) _lightbulbOn += value; } remove { lock (this) _lightbulbOn -= value; } } // ... } You can see that much of this is boilerplate. In Ruby I'd be able to do something like this: class Microwave has_events :door_closed, :lightbulb_on, ... end Is there a similar shorter way of removing this boilerplate in C#?

• Psycopg2 doesn't like table names that start with a lower case letter

  - by Count Boxer

  I am running ActiveState's ActivePython 2.6.5.12 and PostgreSQL 9.0 Beta 1 under Windows XP. If I create a table with an upper case first letter (i.e. Books), psycopg2 returns the "Programming Error: relation "books" does not exist" error message when I run the select statement: execute("SELECT * FROM Books"). The same error is returned if I run: execute("SELECT * FROM books"). However, if I change the table to a lower case first name (i.e. books), then either of the above statements works. Are tables name supposed to have a lower case first name? Is this a setting or a feature or a bug? Am I missing something obvious?

• Does anyone use AODL in a real application?

  - by HyperQuantum

  We are currently using the Excel interop API in .NET to generate simple spreadsheet documents from a template. So we load the template first, insert some rows, fill in some data (dates, text, and numbers), and make Excel visible so that the user can print or save the document we just generated. But I'd like to get rid of the Excel dependency, and switch to the ODF format as well. Googling suggests AODL (C# libs for generating ODF docs) as the most obvious solution. But their last release is 1.3.0.0 BETA, and seems to be 3 years old. So I'm not sure if it's a good idea to depend on a potentially dead project... In that case, I'd need to find another solution. Any ideas? Or maybe someone could assure me that AODL is still alive?

• Neo4j+Gremlin : Trouble with T.gte and floating point node attributes

  - by letronje

  For a type of nodes in my graph, attribute values for an attribute(named 'some_count') is either missing or an integer or a float. I'm trying to write gremlin to filter these nodes based on minimum value for this attribute. I first verified that the values are indeed present by firing the following gremlin g.v(XXX)._().in('category').hasNot('some_count', T.eq, null).back(1).some_count Next, I tried filtering by exact value and that works and show me the matching nodes or gives an empty array if there is no match g.v(XXX)._().in('category').hasNot('some_count', T.eq, null).back(1).has('some_count', T.eq, 120000.0d) But the following query that uses the 'greater than or equal to' comparator doesn't work. g.v(XXX)._().in('category').hasNot('some_count', T.eq, null).back(1).has('some_count', T.gte, 1.0d) this returns nil (I'm querying via ruby/rails using Neo4j AR Adapter ) Instead of returning an empty array for no match, it returns a nil, which tells me something could be wrong with the query itself. I'm running neo4j community server 1.8. Is there a way I can ask Neo4j to log errors/queries, to see what could be going wrong ?

• How might you unobtrusively enhance the jQuery Datepicker class?

  - by Teflon Ted

  You can pass special strings into jQuery's Datepicker class setDate() method like "+7" which will be translated into "7 days from today": http://docs.jquery.com/UI/Datepicker#method-setDate But you can't get that "+7" back out. When you call getDate() you get the calculated resulting date. I have a use case where I need to pull out the special string "+7" for propagation. One chunk of code is passing a special string into the Datepicker and passing the Datepicker over to another chunk of code which pulls out the date, but the latter sometimes needs to know the special string rather than the calculated date. So I need to enhance the Datepicker tool to (a) store the special code internally and (b) expose it via a method like getOriginallyPassedInDate() or some such. I'm not a jQuery/Javascript ninja so I could really use some guidance on how I might preferably-unobtrusively add the necessary functionality to the Datepicker class, the way you might monkey-patch an object in Ruby I'm guessing.

• Getting the last element of a Postgres array, declaratively

  - by Wojciech Kaczmarek

  How to obtain the last element of the array in Postgres? I need to do it declaratively as I want to use it as a ORDER BY criteria. I wouldn't want to create a special PGSQL function for it, the less changes to the database the better in this case. In fact, what I want to do is to sort by the last word of a specific column containing multiple words. Changing the model is not an option here. In other words, I want to push Ruby's sort_by {|x| x.split[-1]} into the database level. I can split a value into array of words with Postgres string_to_array or regexp_split_to_array functions, then how to get its last element?

• Free service that allows storing game data online?

  - by StackedCrooked

  I have created a small game in Java and I would like to add the ability for a player to publish his highscores online. I'm willing to write the server software myself (it's easy these days with Ruby Mongrel, or even C++). All I just need to have some sort hosting. One solution that immediately comes to mind is Amazon EC2. But that's kind of expensive for my needs. Since the requirements are very minimal (I don't even need a website, just a web service) I think there may be a cheaper solution out there. Does anyone know of a free or cheap provider for this kind of thing?

• The D Programming Language for Game Development

  - by n2liquid

  Hi all, Recently I've been bothered because I reached a point in which C++ (even 0x) felt very limited, so I started looking for alternatives. Forget Java, C#, Python or Ruby. I still like the low-level nature of C++ and I'm not fond of virtual machines. Further, I'm a game engine developer, so I have to develop core routines which must be really fast, and lately I've been hungry for code expressiveness. C++ is an almost-there language for me, but there are many exceptions on how to use templates, and GCC isn't optimizing stuff as well as I'd hoped it would. So I'm considering to start learning D. Do you think it will suffice my needs as a game developer? I'm weary because I've never heard of D being used for that. Thanks!

• Current state of Erlang web development? Frameworks, Template languages

  - by pommonico

  Django is to Python as Rails is to Ruby. What is the current front-runner for Erlang? Recent Erlang web activity has resulted in many new frameworks but they are all still moving targets. ErlyWeb is very far along but now seems to be dead. If you were to invest significant capital into a new web product (i.e. not a hobby, you use your own money and you use other's investment in you with expectation of payback), would you choose Erlang as a web platform? If so, what framework and technologies would you choose?

• Is facebook Data Store API available, or a similar/supported persistence mechanism?

  - by jdk

  Question Is there a facebook entry point to a Data Storage mechanism, or should I consider alternatives: What are my alternatives to persist some state information away from my server? ... Background The facebook Data Store Admin tool is made available in a facebook App's Settings (through a link) for the developer to choose as seen here (continue reading below): However when I visit the DataStoreAdmin link nothing works (i.e. clicking the buttons to define the data store types and objects does nothing - I have tried different browsers). The Wiki page for Data Store API hasn't been updated recently and the second last update says the beta Data Store was taken offline. It seems odd the link would be readily available to Apps if the technology is defunct.

• Memory leak in chrome.extension.sendRequest()

  - by jprim

  Chrome Version : 9.0.597.19 (Build 68937) beta & current stable I have simplified my code as far as possible. I ended up with the attached extension: content.js (content script run on every site): setInterval(function() { chrome.extension.sendRequest({ }, function(response) { //Do nothing }); }, 1); background.js (background page script): chrome.extension.onRequest.addListener(function(request, sender, sendResponse) { sendResponse({ }); }); When you install this extension, you can observe it eating up memory extremely fast (I got 90MB in 1 min with 9 tabs opened). You can speed up the process by opening more tabs. Of course, the extension I am actually developing does not send requests every millisecond, but only every 3 seconds. This just slows it down, though. A user who has run it in the background for a long time with many tabs opened has reported 100MB of memory usage, and I can reproduce it to a less extreme extent, too.

• Document conversion and viewing, what are the cutting edge solutions?

  - by DigitalLawyer

  Goal: building a web application where a user can: Upload a document (doc, docx, pdf, additional office formats a +) View that document in a browser, preferably in html Download the document (in doc, pdf, additional open formats a +) Current solution: Ruby on Rails Application on Rackspace Users can upload doc and pdf files (AWS) Files can be downloaded in the format in which they were uploaded Thumbnail generation ([doc, pdf] - pdf - png) is done through AbiWord. Certain doc files do not convert well. Documents can be viewed in embedded Google docs viewer (https://docs.google.com/viewer). Certain doc files cannot be displayed. Little flexibility. Potential improvements: Document viewing in pdf through pdf.js Viewing in html (+ annotation) through Crocodoc I'd be glad to hear other users' experiences, and will add good recommendations to this list.

• How do I search nodes of XML document for text? Or convert to SQL tables?

  - by netefficacy

  Hi I have an XML file and would like to run a search on the nodes for text that matches user input. My options are: Convert the XML file to a SQL table and run the search against the table records. Search the XML nodes themselves. The problem is that I cannot find a open source conversion utility, nor can I figure out how to search the XML nodes. I can use PHP, Ruby, or Python for the search code. Any pointers on how can I do 1 or 2? Thanks

• Interpreters: Handling includes/imports

  - by sub

  I've built an interpreter in C++ and everything works fine so far, but now I'm getting stuck with the design of the import/include/however you want to call it function. I thought about the following: Handling includes in the tokenizing process: When there is an include found in the code, the tokenizing function is recursively called with the filename specified. The tokenized code of the included file is then added to the prior position of the include. Disadvantages: No conditional includes(!) Handling includes during the interpreting process: I don't know how. All I know is that PHP must do it this way as conditional includes are possible. Now my questions: What should I do about includes? How do modern interpreters (Python/Ruby) handle this? Do they allow conditional includes?

• HTML block nested in PHP if statement - is this considered bad practice?

  - by JYelton

  Consider the following example: <table> <tr> <td>Row One</td> </tr> <?php if ($rowtwo) { ?> <tr> <td>Row Two</td> </tr> <?php } ?> </table> If $rowtwo is true, the second row is output, otherwise it is skipped. The code works as desired, however I am evaluating Netbeans (7 beta) as a PHP IDE (instead of just using a text editor). Netbeans flags the code with an error: Misplaced non-space characters insided [sic] a table. Should I consider an alternate way of writing this code, or is Netbeans incapable of understanding this flow control wrapper for HTML output?

• What programming language do you wear a suit for?

  - by Paul

  My company writes mostly .NET code, I work in a professional, 'business casual' environment. Both of these things seemed pretty ubiquitous across the corporate software world, however I recently visited a few companies that use PHP/Ruby and nearly all their devs had facial piercings/visible tattoos, etc. and their offices had no apparent dress code. This might sound funny, but it made me wonder, is there any correlation between specific technology and office culture? For example, have you ever had to wear a suit to a programming job, and if so what technology did you use?

• How to submit an app that uses an iOS6 feature?

  - by Darren

  I'm ready to submit my app to apple, however it says on the iOS Dev portal that xCode 4.5 cannot be used to submit apps yet, use the public release. xCode 4.4 wont compile my project because I am using -(NSUInteger)supportedInterfaceOrientations { return UIInterfaceOrientationMaskPortrait; } which is the new way to support orientation changes. It seems strange with iOS6 round the corner that I cannot submit this. Must I remove this and submit, then resubmit to support iOS6 when they allow it, or has anyone successfully submitted from xCode 4.5 beta 4? Thanks

• References/walkthroughs for maintaining database schemas with Visual Studio 2010?

  - by user206356

  I have Visual Studio 2010 Beta 2 and SQL Server 2008 installed. I'm working with a populated database and want to modify various column types. SQL Server Management Studio requires me to drop tables to do this, and get pretty finicky given my moderate level of knowledge of SQL Server. However, I heard the new database project type supports changing the database schema to the desired format and it will handle creating and running all the scripts to implement the changes. I've created a VS2010 database project using the existing database as the source, but so far haven't had much luck figuring out the appropriate method to make the changes without getting an error. As a result, I'm looking for any reference info I can find on using VS2010's capabilities in this area. Any suggestions?
