• How to implement following with Zend navigation?

  - by simple

  I have a top navigation and a side one Home | Tours | Booking Tour1 ------ Tour2 ------ Tour3 I show the side menu depending on a active top item. But sometimes when the side menu item is clicked I have to show that items children instead of the sidemenu. When no children exist I just show Children of a top menu depending on the active item. I an really having difficulties implementing that kind a logic and any help would be appreciated. //Comment button is not working so I will add comments here After stumbling the zend navigation view helpers, I am coming to the point - Understanding the concept of how in zend V part of MVC is implemented can save someone who is new to the framework many hours. As said in the answer to this question - "Use what is available", thought first we have to know where to find what is already available out there - that is where comes handy to take a look at the concept of helpers and so forth.

• .Net with single .exe without .NET Framework installation

  - by user156144

  I wrote my simple desktop program in C#. I am reluctant to distribute it on the internet because i am not sure if users will go through pain of installing the .Net Framework. My target users are non-tech savvy users. I am very familiar with MFC and I probably can write this program in MFC in a month. MFC is nice because I don't have to worry about distributing other components. It will be one nice single executable. So my real question is this: Is it possible to write .Net app without worrying about distributing .Net Framework? Update I found another solution: If you are using Innosetup, there is a script that installs .net framework. http://www.codeproject.com/KB/install/dotnetfx_innosetup_instal.aspx

• How to use xcode compiler warnings to determine minimum IOS deployment target

  - by Martin Bayly

  I'm building an iOS app using Xcode 3.2.5 with the Base SDK set to iOS 4.2 I know I've used some api's from 4.0 and 4.1 but not sure about whether I actually require 4.2. According to the iOS Development Guide, "Xcode displays build warnings when it detects that your application is using a feature that’s not available in the target OS release". So I was hoping to use the compiler warnings to derive my minimum OS requirement. However, even when I set my iOS Deployment Target to iOS 3.0, I still don't get any compiler warnings. I must be doing something wrong, but not sure what? Can anyone confirm that they get compiler warnings when the iOS deployment target is less than the base SDK and the code uses base SDK functions? Or do the compiler warnings only show if you link a framework that didn't exist in the iOS deployment target version?

• Places to start for system programmer transitioning to web programming

  - by Sean Ochoa

  So here's where I'm coming from: My background is in C#, C++, VB Script, php, javascript, PowerShell, T-SQL, and VB 6. I have some experience with python, and a brief introduction to Ruby On Rails. At work, we're transitioning to a web based UI in the next year or so, but in asp.net & SilverLight. I would like to, if possible, learn more open source web technologies on the side. And, hopefully, in a year and a half or so, I would like to transition to a more open source web technology position. I found that I do really like python, but I'm open to pretty much anything. And yes, I do know Linux (ubuntu and gentoo), as well. And, here's my question: What technologies, frameworks, IDEs, or systems should I be highly proficient in to become a prime candidate for a position doing web application development using non-Microsoft technologies?

• Need to copy remotely hosted file vis Shell Command

  - by pnm123

  Hello, There is a file that hosted remotely on a server that is not supporting Shell Access. I bought a new server that supports Shell Access so now I want to copy a file that is on the non-supporting server to new server via a Shell Command using Putty. File url is like this http://www.domain.com/file.gzip and it is username/password protected. If I be more specified, I want to copy a backup of a home directory from cPanel to my new server via Shell command. I have done this few months ago but I don't remember it now and also I failed to google it. Thank you, Prasad

• Estimate gaussian (mixture) density from a set of weighted samples

  - by Christian

  Assume I have a set of weighted samples, where each samples has a corresponding weight between 0 and 1. I'd like to estimate the parameters of a gaussian mixture distribution that is biased towards the samples with higher weight. In the usual non-weighted case gaussian mixture estimation is done via the EM algorithm. Does anyone know an implementation (any language is ok) that permits passing weights? If not, does anyone know how to modify the algorithm to account for the weights? If not, can some one give me a hint on how to incorporate the weights in the initial formula of the maximum-log-likelihood formulation of the problem? Thanks!

• How do I "Fire and forget" a WinForms Form?

  - by Neil Barnwell

  What's a good technique to create a WinForms Form instance, display it (non-modally) but not have to keep a reference around to it? Normally, as soon as the variable goes out of scope, the form is closed: var form = new SuperDuperForm(); form.Show(); // Form has probably been closed instantly I don't want to have to keep track of instances of the form, I want it so that when the user closes the form, it is disposed. One idea I've had that I'm going to implement is a kind of controller that I use to open and display forms, that will keep track of them and monitor when they are closed via callbacks. I'm just wondering if there are any neat tricks to get away without that. Any ideas?

• What is the most stupid coded solution you have read/improved/witnessed?

  - by Rigo Vides

  And for stupid I mean Illogical, non-effective, complex(the bad way), ugly code style. I will start: We had a requirement there when we needed to hide certain objects given the press of a button. So this framework we were using at the time provided a way to tag objects and retrieve all the objects with a certain tag in a complete iterable collection. So I presented the most logically solution given these conditions to my partner: Me: you know, tag all the objects we needed to hide with the same tag, then call the function to get them all, iterate trough them and make them hidden. Partner: I don't know, that is hardcoding for me... Me: So what do you suggest? 20 mins later... Partner: I don't know... let's put a tag to all the objects to be hidden like this, 1, 2, 3, 4, 5, 6, 7 (and so for each object to be hidden), Then we make a for from 1 to n (where n was the number of objects to hide) and we hide them all there!

• Penalty clause on programming contract

  - by Everyone

  I am considering the move to the other side of development, as a contract programmer. SO has given me a good few hints on the kind of figures to quote ( and why ), and a few points to bear in mind such as Non-competition and [IP Protection] Having worked as a programmer for a while, I know that a few reasons for deadline delays may be - Estimates can be all over the place both from the Contractor, and the Job provider Things like bandwidth bottlenecks, merge for high-impact code etc Clarification time on provided requirements... etc If you have worked as a contract programmer then How frequently do you encounter a penalty/forfeit clause in your agreement? What do you deem unacceptable in the penalty/forfeit clause?

• What is the Reason large sites don't use MySQL with ASP.NET?

  - by Luke101

  I have read this article from highscalability about stackoverflow and other large websites. Many large high traffic .NET sites such as plentyoffish.com, mysapce and SO all use .NET technologies and use SQL SERver for their database. In the article it says SO said As you add more and more database servers the SQL Server license costs can be outrageous. So by starting scale up and gradually going scale out with non-open source software you can be in a world of financial hurt. I don't understand why don't high traffic .NET sites convert their databases to MySQL as it is waay cheaper then SQL Server

• How do I set my development web browser in VS2010?

  - by blesh

  I don't like to use IE for my system default web browser. but I do want to set IE as my browser in VS2010 because it works a little nicer for debugging and I like to develop to the lowest common denominator. (jab, lol)... anyhow, can I default to debugging against IE? I know in VS2008 you just had to "Browse With..." on an .aspx page. But that option doesn't exist in VS2010 RC. What gives?

• Identifying which value of a multi-row inserts fails foreign key constraint

  - by Jonathan

  I have a multi-row insert that looks something like: insert into table VALUES (1, 2, 3), (4, 5, 6), (7, 8, 9); Assume the first attribute (1, 4, 7) is a foreign key to another table and assume that this referenced table does not have the value '4'. A MySQLExeption is thrown with error code 1452. EXCEPTION: Cannot add or update a child row: a foreign key constraint fails (dbName/tableName, CONSTRAINT id FOREIGN KEY (customer_id) REFERENCES referencedTable (customer_id)) Is there a way to identify which value caused the error? I would love to give my user an error message that said something like: Error: '4' does not exist in the referenced table. I am using the .NET mysql connector to execute the insert. Thanks- Jonathan

• Methods in super that will be subclassed anyway (Cocoa)

  - by Michael Matheus

  Sorry if this is a repost but I couldn't quite search for it because I can't explain it in a few words. I have a super class with lots of methods but they will always (not all of them) be subclassed. From the super I need to access (read only) those methods. I could either leave the methods in super empty or I could just not type them in super but call them anyway like so [self myMethod] and it will call my subclassed method even if it doesn't exist in super. This works but Xcode gives me an error though. 'superclass' may not respond to '-subclassmethod' What should I do?

• Lightweight PHP library alternative to common frameworks

  - by artarad

  Hi hi, I'm looking for a easy to learn php library to use for my coming web app project. I've recently finished a web app with fully handwritten raw php code and it's absolutely hard to be done again for another project. even though I have the recent project code snippets to be used again, but due to their non-structural arrangement (not object oriented), i have no passion to use 'em again. I have no experience with common frameworks like ZF, CakePhp, CodeIgniter, so I think to get my hands on a multipurpose OO library for my web app and the framework learning will be the next step! any suggestion? UPDATE: Many thanks guys, I have not enough time to get through the depth of every lib or framework you have kindly introduced. Since I'm going one step further I'm going to use ZF as famous framework which could provide me more job opportunities perhaps. thankssss :)

• How to center an R plot after removing axis labels

  - by ConnorG

  I'm working on visualizing a matrix in R (almost exactly like http://reference.wolfram.com/mathematica/ref/MatrixPlot.html), and I've been using image(<matrix>,axes=FALSE) to draw the picture. However, I noticed that with the y-axis turned off, the plot isn't centered--the space is still there for the axis ticks + label. I can finagle some centering with par(oma=c(0,0,0,2.5)) but this seems inefficient and error-prone (if my matrix were to change dimensions/become non-square). Is there a better way to force the graphic to center? The right hand margin is significantly smaller than the left.

• Building a subquery with ARel in Rails3

  - by Christopher

  I am trying to build this query in ARel: SELECT FLOOR(AVG(num)) FROM ( SELECT COUNT(attendees.id) AS num, meetings.club_id FROM `meetings` INNER JOIN `attendees` ON `attendees`.`meeting_id` = `meetings`.`id` WHERE (`meetings`.club_id = 1) GROUP BY meetings.id) tmp GROUP BY tmp.club_id It returns the average number of attendees per meeting, per club. (a club has many meetings and a meeting has many attendees) So far I have (declared in class Club < ActiveRecord::Base): num_attendees = meetings.select("COUNT(attendees.id) AS num").joins(:attendees).group('meetings.id') Arel::Table.new('tmp', self.class.arel_engine).from(num_attendees).project('FLOOR(AVG(num))').group('tmp.club_id').to_sql but, I am getting the error: undefined method `visit_ActiveRecord_Relation' for #<Arel::Visitors::MySQL:0x9b42180> The documentation for generating non trivial ARel queries is a bit hard to come by. I have been using http://rdoc.info/github/rails/arel/master/frames Am I approaching this incorrectly? Or am I a few methods away from a solution?

• Does ImageIO read imply anti-aliased scaling?

  - by tigger

  I've replaced the Java internal ImageFetcher with an own implementation using ImageIO. Some image renderers of our software, which use these images, now draw anti-aliased scaled images instead of non anti-aliased. The only change is the source of the image, which are now BufferedImages instead of Toolkit-Images. The question now is, where is the difference? Which property causes the images to scale anti-aliased? I've always thought that the anti-alias key ONLY depends on the graphics I paint on - but this is obviously wrong. By the way: unfortunately I cannot change the renderers.

• Visual Studio 2008 adding incorrect working folders to TFS Workspace

  - by Bryan Rowe

  I am using Visual Studio 2008 with TFS. I have one workspace set up with one working folder. I map the root source control folder $/ to C:\TFS and get all code. When working on any project under the root, Visual Studio will randomly add incorrectly mapped working folders to my workspace. For example, it might map $/WebProject/ to C:\TFS\WebProject\DataAccess -- where the real files exist at C:\TFS\WebProject. Once it incorrectly adds these working folders, I can no longer open the solution. I am forced to remove the working folders that Visual Studio added and get latest from TFS. Has anyone experienced this? Is there something I can do to avoid running into this?

• Should integration testing of DAOs be done in an application server?

  - by HDave

  I have a three tier application under development and am creating integration tests for DAOs in the persistence layer. When the application runs in Websphere or JBoss I expect to use the connection pooling and transaction manager of those application servers. When the application runs in Tomcat or Jetty, we'll be using C3P0 for pooling and Atomikos for transactions. Because of these different subsystems, should the DAO's be tested in a fully configured application server environment or should we handle those concerns when integration testing the service layer? Currently we plan on setting up a simple JDBC data source with non-JTA (i.e. resource-local) transactions for DAO integration testing, thus no application server is involved....but this leaves me wondering about environmental problems we won't uncover.

• .NET Regular expressions on bytes instead of chars

  - by brickner

  Hi, I'm trying to do some parsing that will be easier using regular expressions. The input is an array (or enumeration) of bytes. I don't want to convert the bytes to chars for the following reasons: Computation efficiency Memory consumption efficiency Some non-printable bytes might be complex to convert to chars. Not all the bytes are printable. So I can't use Regex. The only solution I know, is using Boost.Regex (which works on bytes - C chars), but this is a C++ library that wrapping using C++/CLI will take considerable work. How can I use regular expressions on bytes in .NET directly, without working with .NET strings and chars? Thank you.

• ASP.NET HTTPHandler not throwing exception when one is expected

  - by josephj1989

  I have an HttpHandler class (implements IHttphandler) where the path defined for the handler in web.config is *.jpg. I am requesting a Jpg image in my page. Within the HTTP Handler I am writing to a file in the filesystem. By mistake I was trying to write to a non existant directory. This should have thrown an exception but the execution simply proceeds.Ofcourse no file is written. But if I give a proper directory the file is written correctly.Is there anything special about HttpHandler Exceptions. See part of the code public void ProcessRequest(HttpContext context){ File.WriteAllLines(context.Request.ApplicationPath+@"\"+"resul.log",new string[]{"Entered JPG Handler"}); If I put a breakpoint on the File.WriteAllLines statement and then step over it I can see an exception occurring.
