• Problem with MvcContrib

  - by Sasha

  I want to use MvcContrib Grid helper, but i stuck on the problem - it's not working. I downloaded release for mvc 1, i have dll on my hard drive, i added a reference to my project, but i always getting following error: 'System.Web.Mvc.HtmlHelper' does not contain a definition for 'Grid' and no extension method 'Grid' accepting a first argument of type 'System.Web.Mvc.HtmlHelper' could be found (are you missing a using directive or an assembly reference?) I am using Visual Web Developer 2008 if this is important The question is: how correctly add this to my project? Can you give me step by step instruction? Thanks

• are there any negative implications of sourcing a javascript file that does not actually exist?

  - by dreftymac

  If you do script src="/path/to/nonexistent/file.js" in an HTML file and call that in a browser, and there are no dependencies or resources anywhere else in the HTML file that expect the file or code therein to actually exist, is there anything inherently bad-practice about doing this? Yes, it is an odd question. The rationale is the developer is dealing with a CMS that allows custom (self-contained) javascript files to be provided in certain circumstances. The problem is the CMS is not very flexible when it comes to creating conditional includes for javascript. Therefore it is easier to just make references to the self-contained js files regardless of whether they are actually at the specified path. Since no errors are displayed to the user, should this practice be considered a viable option?

• How to learn flex?

  - by Zenzen

  So I'm starting an internship as a Flex developer in ~2weeks thanks to a friend of mine. The thing is I know squat about Flex - it is an internship after all so I'm supposed to learn there, but nonetheless I want to have some basic understanding of Flex before I start (eventually I want to become a JEE/Flex dev). So my question is simple, which book(s) would you recommend me to start with? Are there any "must have" books, like let's say "Thinking in C++" for C++ etc.? I already heard about a few video tutorials and I will surely check them out but I'd also want to get some decent books.

• Drupal Views pulling Data Fields

  - by askon

  I'm a little new to drupal but have been using things like devel module and theme developer to speed up the learning process. My question, is it possible to theme an entire views BLOCK from a single views tpl.php page OR even a preprocess? When I'm grabbing the $view object I can see results $node-result, it has all of the results, but it doesn't have all my views fields. I'm missing things like, node path, taxonomy titles and paths, etc. From my understanding, Drupal wants you to individually theme EACH output field. It seems rather superfluous to create so many extra templates when I've already got over HALF of my results coming through the $view object Would outputting node over field make this easier? Or am going in the wrong direction with $view-result? Thanks!

• arm-apple-darwin9-g++ Bus error problem

  - by overboming

  I want to create a mobilesubstrate plugin for iPhone OS 3.2 or I tried to setup toolchain on the iPad device. I have installed the iphone-gcc_4.2-20090304-1-9_iphoneos-arm package and all the relevant packages from Cydia, but when it comes to compiling the simplest source file shows the following error: arm-apple-darwin9-g++ -I /var/toolchain/sys/ -c -dynamiclib ExampleHookLibrary.mm -o ExampleHookLibrary.o arm-apple-darwin9-g++: Internal error: Bus error (program cc1objplus) Please submit a full bug report. See <URL:http://developer.apple.com/bugreporter> for instructions. make: *** [ExampleHookLibrary.o] Error 1 Is it because the iphone-gcc doesn't yet support this device or am I missing anything here? Thanks.

• Learning resources for Linux filesystem, command line, and structure

  - by webworm

  Can anyone suggest some good materials for learning more about the Linux filesystem and command line? I have found myself frequently confused as to what programs go where on the Linux filesystem. I would like to learn how the various directories (var, etc, usr ...) are used and how to use the commandline more effectively. I come from the Windows development world (.NET developer) so I am very familiar with Windows system administration. However, when doing more and more work with PHP I found myself lost in the internals of Linux (specifically Ubuntu). For example I was having problems installing PEAR properly on my Ubuntu system and not understanding why it was installed where it was. All of my interactions with Linux machines is done via SSH so I would like to focus on the command line and the filesystem. Thanks for any suggestions.

• 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.

• How to parse a text file and write the result to an xls file?

  - by Bk

  Hi all i am a junior level SQL developer. I have a situation where I have a text file with 1100 lines of a search result with each line containing a file path and a stored procedure associated with that file. Each line has a structure like the one below: abc\def\ghi\***.cs(40): jkl=******.*****.******, "proc_pqrst", parms); Where abc\def\ghi\***.cs is file path of the file ***.cs. The stored procedure names begin with proc_. I have to extract the ***.cs and the corresponding stored procedure name begining with proc_ and write them to a .xls file. Can some body help me in writing the parsing program to do this? Also can I get a detailed outline on where should I write the code for c# and where should I compile it? This could be a great help as I don't have any knowledge of C#. Thank you, BK.

• Internet Explorer generates extra br

  - by ahsteele

  I have an issue where Internet Explorer is generating an additional br element that is not in my source. The additional br effects the page's layout and is visible when using the developer tool. I've tried removing all hard returns between the surrounding elements but the additional br persists. Firefox and Chrome do not have this issue. Ideas on what I can do to fix the issue? Instead of First line. Second line. I get First line Second line. Code Example <asp:ImageButton ID="RemoveItem" AlternateText="Remove Item" ImageUrl="~/img/buttons/remove.png" runat="server" CssClass="remove" CommandName="Remove" OnCommand="RemoveCartItem_Command" /> <br runat="server" id="TotalBreak" />

• Simple cross platform GUI app

  - by Joe Cannatti

  I would like to know if there is any way that I could build a very simple GUI app (it doesn't even have to look good) that will run on a fresh install of Windows Vista and OS X with no other installations needed by the user. I would perfer not to use Java (just out of personal programming preference). I will use it though, if it is the only way. Specically, I am wondering if I can write a swing app with Scala or Groovy and run in on windows without them having to install anything. Sorry if this is a silly question, I am a Obj-C developer by trade.

• what pattern to use for multi-argument method?

  - by Omid S

  I have a method with the following signature: foo (Sample sample, Aliquot aliquot) "foo" needs to alter a Sample object, either the first argument or from the second argument it can extract its Sample. For example: foo (Sample sample, Aliquot aliquot) { Sample out = null; if (sample != null) out = sample else out = aliquot.getSample() return out; } But that is so un-elegant, other than reading the API a developer does not know the reference of the first argument overrides the Sample of the second argument. Now, I could change "foo" to foo (SomeMagicalObject bar) where SomeMagicalObject is a tuple for Sample and Aliquot and holds some logic ... etc. But I am wondering, are there some patterns for this question?

• Looking for Suggestion on Multi-Consumer Service Development

  - by DaveDev

  How would I model a system that needs to be able to provide content in a format that would be consumable by iphone, Android or web browser (or whatever). All a new consumer would have to do is build a UI with rules on how to handle the data. I'm thinking something RESTful returning JSON or something. I'm really looking for suggestions on the kinds of things I'd need to learn in order to be able to implement a system on this scale. As an ASP.NET MVC developer, would that be the best framework/archetectrue to go with? Thanks

• RedDot with Lotus Notes support

  - by fredde

  Hi, First post here in SO. I have a question within the area of CMS (RedDot) and possible integration of some Lotus Notes functionality. I'm very fresh in both areas. From my short research (did not find very much material regarding RedDot) I got the following: Contents in RedDot CMS can be accessed (and modified?) via the RQL API. (basicly xml messages) There exists a API developed for Java (jRQL). Lotus Notes has a developer kit called Lotus Expeditor Toolkit. My vague question is something like this: Is it possible to integrate a some kind of "content approver/manager" or any other useful CMS functionality from Lotus Notes into the RedDot CMS system? In that case I was thinking of using the jRQL and Lotus Expediton Toolkit so that the back end is fully using Java. Or is there any better solution? Regards Fredrik

• Are we in a functional programming fad?

  - by TraumaPony

  I use both functional and imperative languages daily, and it's rather amusing to see the surge of adoption of functional languages from both sides of the fence. It strikes me, however, that it looks rather like a fad. Do you think that it's a fad? I know the reasons for using functional languages at times and imperative languages in others, but do you really think that this trend will continue due to the cliched "many-core" revolution that has been only "18 months from now" since 2004 (sort of like communism's Radiant Future), or do you think that it's only temporary; a fascination of the mainstream developer that will be quickly replaced by the next shiny idea, like Web 3.0 or GPGPU? Note, that I'm not trying to start a flamewar or anything (sorry if it sounds bitter), I'm just curious as to whether people will think functional or functional/imperative languages will become mainstream. Edit: By mainstream, I mean, equal number of programmers to say, Python, Java, C#, etc

• Sum an Array - Objective-C

  - by Graham

  Hi Guys, I'm just starting out and I'm looking for an easy way to sum a simple array. I've read into apple developer site on key value coding and I don't understand how to apply that to my array or if that's the appropriate way to sum this. My stumbling block with the key value coding is the .keypathToProperty - I can sort of understand that you need a further reference in a 2D array but they don't show the array code, only the keypath to the title of the row so I can't figure it out yet. NSMutableArray *numArray = [NSMutableArray arrayWithCapacity:4]; [numArray addObject:num1]; [numArray addObject:num2]; [numArray addObject:num3]; [numArray addObject:num4]; I appreciate the replies! Thanks Graham

• Do you have to install the REST starter kit in asp.net to access APIs?

  - by jonhobbs

  Hi, I'm currently trying to access a REST API for the first time using visual web developer 2008 express edition. Every article I have found says you have to install the WCF REST starter kit which is a .msi file, which would suggest that I have to install it on my machine and presumably our server too. My question is this. Is there a non installable version that I can use, e.g. just by dropping DLLs into the Bin directory and then using the classes contained. Or is there more to it than that and am I just getting very confused about how it works? Jon

• What could cause "Connection Interrupted" on LocalHost when debugging in ASP.NET

  - by Jeff Dalley

  I'm trying to run a freshly created ASP.NET Website using C#, however when I do so it launches FireFox and attempts to connect to http://localhost:1295/WebSite1/Default.aspx (for example), but after about 10-15 seconds it displays a "Connection Interrupted - The connection to the server was reset while the page was loading." Error. This issue is also present with older ASP.NET C# pages/Web Services I've built in the past, nothing is actually running off the ASP.NET Development server. I am using: Windows XP Pro SP2, Visual Studio 2008 For reference I have SQL Server 2005 Developer Edition installed as well. I have tried: Browsing it with IE instead of Mozilla Trying 2.0 framework instead of 3.5 Reinstalling Visual Studio 2008 This problem seems so trivial the more I think about it, but I havn't been able to work it out just yet! Appreciate any help on the matter.

• Cities to Metropolitan areas

  - by user325377

  Hi all, I have a database of cities (in both the US and the rest of the world). The database entries are simple text strings. Currently the database contains even small cities (population 10,000). I wish to use a larger scale database instead, by assigning the cities into larger geographical\metropolitan areas. An example can be the Metropolitan areas in Google's AdWords API: http://code.google.com/intl/iw-IL/apis/adwords/docs/developer/adwords_api_us_metros.html but I have no problem using other databases instead. I'd be grateful for any advice on how this can be performed using existing databases\APIs!

• What are the best uses for each programming language?

  - by VirtuosiMedia

  I come from a web developer background, so I'm fairly familiar with PHP and JavaScript, but I'd eventually like to branch out into other languages. At this point, I don't have a particular direction or platform that I'm leaning toward as far as learning a new language or what I would use it for, but I would like to learn a little bit more about programming languages in general and what each one is used for. I've often heard (and I agree) that you should use the right tool for the job, so what jobs are each programming language best suited for? Edit: If you've worked with some of the newer or more obscure languages, please share for those as well.

• OpenDACS .Net Framework

  - by Goober

  Scenario As some of you may have heard, OpenDACS is an open source data-access control system for enforcing data usage permissions. DACS comes integrated with the Reuters platform but you can use OpenDACS for extending third-party software. I'm using IE6, I can't embed these links properly. http://thomsonreuters.com/products_services/financial/financial_products/real-time/data_access_control_system https://customers.reuters.com/developer/Kits/OpenDACS/opendacs.aspx Question Has anyone used OpenDACS at all? I'm quite interested in it but I have no idea where to start. Ideally some examples would be fantastic, or a startup guide. Thoughts I use C# heavily and am looking to extend a C# application with DACS. I understand that there is currently no C# API, however I've heard that the SFC-COM Edition can used with the .Net/COM interoperability layer Help greatly appreciated. Cheers.

• What should I consider when deploying a new web farm?

  - by tsilb

  My web app has been chugging along just great in Production for years with one App server and one Web server. Now we're moving to a multi-server environment with 2 App and 3 Web servers. I have enough time to make changes before the go-live. As a Developer, what considerations should I take into account from coding, deployment, and architectural/ecosystem management perspectives? Already on my list: Remove tight-coupling between servers Applicable files (i.e. downloadables) stored in IMAGE fields in SQL instead of files on app server Deployment: Take out node out of the farm at a time

• Importing large datasets on iPhone using CoreData

  - by Matthes

  Hi there, I'm facing very annoying problem. My iPhone app is loading it's data from a network server. Data are sent as plist and when parsed, it neeeds to be stored to SQLite db using CoreData. Issue is that in some cases those datasets are too big (5000+ records) and import takes way too long. More on that, when iPhone tries to suspend the screen, Watchdog kills the app because it's still processing the import and does not respond up to 5 seconds, so import is never finished. I used all recommended techniques according to article "Efficiently Importing Data" http://developer.apple.com/mac/library/DOCUMENTATION/Cocoa/Conceptual/CoreData/Articles/cdImporting.html and other docs concerning this, but it's still awfully slow. Solution I'm looking for is to let app suspend, but let import run in behind (better one) or to prevent attempts to suspend the app at all. Or any better idea is welcomed too. Any tips on how to overcome these issues are highly appreciated! Thanks

• Way to check files in and out with multiple developers.

  - by Roeland

  I am a web developer working with 2-3 people including me. Our current setup is very simplistic. We try to let each other know when we are working on a specific file. We use FTP to edit our files. Recently we have run into the problem of 2 people accidentally editing one file, or working on a local file then uploading when another person just did the same. From what I have read I need some sort of control system. I have heard of subversion and mercurial. It seems that these systems may not be what I need though, since its just giving me different versions of the files. I don't know if it solves the issue of two people working on a file and overwriting each others work. What are your suggestions for solving my problem?

• Rails - authoritative source for your database schema?

  - by keruilin

  I have Rails app, and every once in a while, when I bring new developer onboard they exclaim that they should be able to produce the current DB schema in their dev environment by running the whole history of the migrations. I personally don't think that migrations is the authoritative source for your schema. Right now what we do is load a production copy of the DB, with the current schema, onto the dev machine. And, from there, the schema can be maintained via incremental migrations. So my question are: What is the authoritative source of your schema on a Rails project? What is now considered the best-practice way to maintain your DB schema?

• Which Workflow Engine do you recommend?

  - by Glenn

  I am kicking around the idea of using a workflow engine on this upcoming project. We know that there is a lot of caveats with using a workflow engine and we have a lot of development experience in many platforms so we would be willing to let the choice of workflow engine take precedence over our favorite toolset or developer IDE. We are more interested in internal workflow (i.e. petri net for easily changeable ERP purposes without involving additional coder time) than external workflow (i.e. aggregating SOAP calls into a transaction aware, higher level SOA). Which workflow engine would you recommend? We have superficially looked at offerings by Oracle, Microsoft, and some open source stuff too. It's all very overwhelming so please respond only if you have real life experience with implementing internal workflow.
