• Limit VS2010 Intellisense Camel Case matching

  - by Gabriël

  Hi, I just started with VS2010 and the feature I was really looking forward too was the new Intellisense, and the Camel casing matching in particular. But I must say I'm pretty dissapointed with the way it works and am wondering if this is just a setting, or not. When I type 'OIE' I get the following results: OrderItemBackerEntity (OIBE) OrderGarmentActionGroupItemEntity (OGAGIE) OrderItemClothingEntity (OICE) OrderItemEntity (OIE) << GOOD These indeed do match in some way, but why does it match so broad, and not only the fitting one, the last one. Are these settings, or is this by design?

• Question about migrating from ASP .NET User Controls to .NET 3.5 Master Page technology

  - by Jim McFetridge

  When migrating from an ASP .NET user control -based page with a header, footer, and menu to a Master Page using the same HTML mark-up, is it normal for CSS or javascript behaviors to change slightly? In particular, the submenu bar text now appears run together (which looks like a CSS symptom) and the graphics on the line above it appear to have an incorrect z-order. (The menu operation is javascript-based.) (I tried to paste images here but couldn't.) Also, the site is very large and we've not been given permission to redo the menu for the entire site. This is a forward-only migration. (Because I know that someone will ask.) Assuming that there are no changes in scope, what are the things that I should check? Thanks! Jim

• Using code in both Actionscript3 and Javascript

  - by Ian

  Here's an interesting architectural query. I have a piece of code that needs to run on the server (under Node.js) and on the client (in a Flash 10 app written with Actionscript 3). The code is mostly fairly intricate object manipulation, it doesn't make any API calls, and works fine in both contexts. So far the project is just a demo, so I've been happy to copy and paste the code into both places. But it might be quite interesting to move forward with this. So how would you do it? I assume there is no easy way to get the Flash SDK (has to build without an IDE) to read and do something useful with a .js file. My only thought is that I could write a code-generator that takes the .js file and places it in an ActionScript wrapper. Are there any obvious approaches that I've missed? Just to pre-empt an obvious answer, I know about cross-platform languages like HaXe.

• Paging doesn't work in the Joomla Article Manager in the admin section

  - by SkippyFire

  I inherited a Joomla site that is having a problem with the article manager in the admin section. The pagination doesn't work! If I click the page number, forward, back, or page size, nothing happens! So I found out that someone had previously installed the iJoomla SEO plugin, but it never worked so they removed it. I think it is incompatible with the version I have. I setup a local environment with almost the same setup (I have 5.2.11 vs the servers 5.2.13) with Wamp Server, and I found that some of the session variables are missing! When dumped via print_r(), the $_SESSION variable is missing the "com_content", "global", and "com_plugins" arrays! So I guess that is the reason that paging doesn't work, because the "com_content" array looks like it has paging info in it. (maybe I'm wrong) So I'm running Version 1.5.13 on PHP Version 5.2.13 Anyone know why this would happen? Thanks in advance!

• When is performance gain significant enough to implement that optimization?

  - by Zwei steinen

  Hi, following the text book, I do measure performance whenever I try optimizing my code. Sometimes, however, the performance gain is rather small and I can't decisively decide whether I should implement that optimization. For example, when a fix shortens an average response time of 100ms to 90ms under some conditions, should I implement that fix? What if it shortens 200ms to 190ms? How many condition should I try before I can conclude that it will be beneficial overall? I guess it's not possible to give a straight forward answer to this, as it depends on too many things, but is there a good rule of thumb that I should follow? Are there any guideline/best-practices?

• Tomcat - virtualhosting - name / ip / port - based

  - by lisak

  Hey, what are the usage scenarios for these kinds of virtual hosting ? Name Based - typical tomcat virtual hosting, one HOME instance with many contexts, each as an individual host IP based / port based - multiple instances of tomcat ( how is it with performance and memory consuption?) running on IP aliases (virtual IPs) for one network adapter, usually behind http apache server that can run name based virtual hostings. Otherwise I can't figure out how would I forward requests in iptables/firewall based on IP address, which is just one. How is IP based virtual hosting done as to Tomcat and multiple instances ? I'd like to hear some usage scenarios from your experience. How are you running your applications. Cause there are applications having it's own modified classloader and they are developed in a way to run alone withing a tomcat instance. Then there are trivial applications which can run within one instance without problems. Many thanks

• Run Windows XP on a usb drive virtually on Windows XP?

  - by Russell

  I am sick of not being able to run and install certain applications on my work computer due to admin restrictions (eg: Adobe AIR) . I have heard of smaller versions of Windows running on a usb thumb drive and have looked into it but can't find anything on running windows virtually from a usb drive. I would like to be able to login to this particular computer, insert my usb drive and then open up another version of windows installed on the thumb drive while still being able to use the windows I logged in on (literally be able to alt+tab between the main desktop and the virtual desktop from the usb drive). Is this even possible? For further clarification: The version of windows has to be Windows XP and there is no other option available for what I want to do. Looking forward to a response.

  - by Rachel

  I was going through Questions every good .Net developer should be able to answer and was highly impressed with the content and approach of this question, and so in the same spirit, I am asking this question for Java/J2EE Developer. What questions do you think should a good Java/J2EE programmer be able to answer? I am marking this question as community wiki as it is not user specific and it aims to serve programming community at large. Looking forward for some amazing responses. EDIT: Please answer questions too, as suggested in the comments, so that people could learn something new regarding the language, too.

• Formatting address of different types

  - by mickyjtwin

  I have various classes which all contain address details, i.e. AddressLine1, AddressLine2, AddressLine3, Suburb, Town, etc. On the front end, I need to format the address in a particular way, i.e. AddressLine1<br /> AddressLine2<br /> Suburb State Postcode If AddressLine2 does not exist or empty, don't show it. Quite straight-forward. I am trying to determine the best way to show this info. At the moment, the Address property of each class calls a FormatAddress method which writes out the html string. This exists as a method of the class. My opinion is that any formatting should exist from the front-end control i.e. ascx etc. However, if these DetailClasses need to format the same address info, what would be the best option, also making it easier to maintain?

• Alternative to COM blind aggregation in .NET for class with private interface

  - by Philip

  When extending a COM class in unmanaged C++ where the original class has private interfaces, one way to do this is through the concept of blind aggregation. The idea is that any interface not explicitly implemented on the outer aggregating class is 'blindly' forwarded to the inner aggregated class. Now .NET as far as I can figure out does not support COM aggregation natively. A somewhat tedious workaround is to create a .NET class where you implement all the required COM interfaces directly on the .NET class and simply forward to an instance of the actual COM class for any methods you don't want to override. The problem I have is when the original COM object has one or more private interfaces, i.e. undocumented interfaces that are nonetheless used by some consumers of the original class. Using blind aggregation in unmanaged C++ this is a non-issue as the calls to the private interfaces are automatically forwarded to the original class, however I can't find any way of doing the same thing in .NET. Are there any other ways of accomplishing this with .NET?

• How to catch mousewheel up/down event using RaphaelJs

  - by alex.dominte

  I need to implement a horizontal scrollable timeline. I've drawn the timeline/grids/rulers etc. I just need to catch mousewheel up/down to scroll the timeline (backward - past/forward - future). First I need to catch the event: but nothing I've found seems to work. Need browser support only for chrome/firefox (latest versions). These 2 won't listeners won't work: var paper = new Raphael('raphael-paper'); // ... paper.canvas.on('mousewheel', function(event) { console.log(event); }); // ... paper.canvas.addEventListener('mousewheel', function(event) { console.log(event); });

• Logging from symfony's model layer

  - by naag

  I'm currently working on a project with symfony 1.4 and Doctrine 1.2. I'm looking for a proper way to do logging from the model layer. In some model classes I use the record hook postSave() to create a ZIP file using exec() (since PHP zip doesn't provide for storage method 'Stored'). To be sure that everythings works fine I check the return code and log an error if something goes wrong. My first naive approach was to do it like this: if ($returnCode != 0) { sfContext::getInstance()->getLogger()->debug(...); } As you know, this doesn't work so well because sfContext belongs to the controller layer and shouldn't be used from the model layer. My next try was to use the model's constructor to pass in an sfLogger instance, but this doesn't work due to Doctrine 1.2 reserving the constructor for internal use (Doctrine 1.2 Documentation). I'm looking forward for your suggestions!

• Following Domain Driven Design with MVVM/WPF

  - by msfanboy

  Hello, I have plain POCOs here and as INotifyPropertyChanged is a Interface for the Views need its implemented in the ViewModel not the Model. Now I want to show validation errors in the View beside every textbox the user typed in data. I do not want to implemented the IDataErrorInfo interface in my Models because lets assume I am not allowed to touch them as they come from another Service/Supplier. I do not want to put my IsCustomerFirstNameLenthValid Method into the Model because I could not have access to it or I just dont want to pollute my Models with interface`s having nothing to do there! How can I validate my naked POCO`s in the ViewModel and forward the results to the View by showing validation errors ?

• Generating a scalogram of a signal

  - by Goz

  Hi there, I'm trying to build a scalogram view for my app to see whether there is relevant information we can retrieve from a wavelet transform as opposed to using a spectograms to see what can be retrieved via an FFT. So far I can take a wave form and I can perform the forward wavelet transform on it. However I am lost at the next step. How do I turn this information into power/energy information? I have a set of wave forms at different frequencies but I have, as I say, no frequency information. Can anyone tell me what the next step is for turning this transformed data into a scalogram? Any help would be much appreciated because my google skills are failing me!

• Framework Similar to Pylons for Ruby

  - by Travis

  I've been using Python for most of my web projects lately, and have come to really love the Pylons MVC framework. I like the incredible transparency (lack of magic), the built-in components they selected (sqlalchemy, formencode, routes), and the ability to easily change things up (use a different ORM or templating engine). Moving forward, due to constraints at my company, I'm going to be trying out Ruby rather than Python. I'm wondering if people with experience in both have any recommendations for a Ruby framework that is comparable to Pylons. Python is to Django as Ruby is to Rails Python is to Pylons as Ruby is to ?

• Increment global variable on click in flash, actionscript 3

  Hi, Making a flash page that can cycle through these three images on mouseclick. For some reason the local changes to count are not reflected on the global one. I tried _global but the syntax was odd and gave me errors. How should I implement this? import flash.events.Event; var images:Array = ["images/image.jpg", "images/image2.jpg", "images/image3.jpg"]; var count:int = 0; forward.addEventListener(MouseEvent.CLICK, loadPhoto); function loadPhoto(evt:Event){ if(count>2){ count==0; } trace(count); imageFrame.source = images[count]; count++; }

• Ruby: writing a network redirector

  - by Shyam

  Hi, I would like to research protocols such as HTTP. As I am learning Ruby, I would like to write a program that works as a "gateway". I would be connecting to it's port on for example 8080 and the program should forward my request to the real host and send back the answers. The idea of my design is something like this: class EchoProxy def run # run a listening socket on port 8080 myinfiniteloop end def myinfiniteloop # continually run this loop unless the app is terminated puts traffic end end Some pointers in the right direction would be great! Thank you for your comments, answers and feedback!

• Why might SQL execute more quickly on SQL Server 2000 when NOT using a stored procedure?

  - by Kofi Sarfo

  I could see nothing wrong with the execution plan. Besides, as I understand it, SQL Server 2000 extended many of the performance benefits of stored procedures to all SQL statements by recognising new T-SQL statements against T-SQL statements of existing execution plans (by retaining execution plans for all SQL statements in the procedure cache, not just stored procedure execution plans) It's a fairly straight forward SELECT statement with sensible table joins, no transactions included or linked servers being referenced within the query and WITH (NOLOCK) table hints applied. The stored procedure was created by dbo and the user has all the necessary permissions. So my question is this: What are the likely reasons for a query to take only a few seconds to run but then take several minutes when identical T-SQL is run via a stored procedure?

• .ics Calendar File - Parsing Date Time - What is the time format?

  - by Josh

  I am coding in php, attempting to get the start\end dates and times for events. I am utilizing the following RegEx for parsing out the information: $pattern='/(?P<StartDate>[0-9]{8})T(?P<StartTime>[0-9]{6}) .+(?P<EndDate>[0-9]{8})T(?P<EndTime>[0-9]{6})/'; The sample event entry is here: BEGIN:VEVENT UID:34b09fd7-8e6e-4d56-86b0-445745b89d93 ORGANIZER;CN=*********:mailto:********* DTSTART;TZID="(GMT-06.00) Central Time (US & Canada)":20100413T130000 DTEND;TZID="(GMT-06.00) Central Time (US & Canada)":20100413T160000 STATUS:CONFIRMED CLASS:PRIVATE X-MICROSOFT-CDO-INTENDEDSTATUS:BUSY TRANSP:OPAQUE X-MICROSOFT-DISALLOW-COUNTER:TRUE DTSTAMP:20100414T140711Z SEQUENCE:0 END:VEVENT 20100413T130000 and 20100413T160000 are the start and end points. The dates are straight forward, however how do I interpret the time part? This event starts at one and ends at four.
