• Doctrine Mssql uniqueidentifier isn't cast as char or nvarchar when retrieved from the database.

  - by Tres

  When I retrieve a record from the database which has a column of type "uniqueidentifier", Doctrine fills it with "null" rather than the unique id from the database. Some research and testing has brought this down to a PDO/dblib driver issue. When directly querying via PDO, null is returned in place of the unique id. For reference, http://trac.doctrine-project.org/ticket/1096, has a bit on this, however, it was updated 11 months ago with no comment for resolution. A way around this, as mentioned at http://bugs.php.net/bug.php?id=24752&edit=1, is to cast the column as a char. However, it doesn't seem Doctrine exposes the native field type outside of generating models which makes it a bit hard to detect uniqueidentifier types and cast them internally when building the sql query. Has anyone found a workaround for this?

• Pool Billiard AI

  - by Sebi

  Im implementing a pool billiard game in Java and it all works fine. It is a multiplayer game, but nevertheless, it should also be possible to play it alone. For this purpose I'm trying to implement a simple KI. At the moment, the KI choose just randomly a direction and a random intensity of the impulse (don't know the correct english word for that). Of course this AI is very poor and unlikely to ever challenge a player. So i thought about improving the KI, but there are several hard to solve problems. First I thought of just choosing the nearest ball and to try to put it directly into the nearest hole. This isn't that bad, but if there other balls in the line between, it isn't really working anymore. Additionally this dosn't solve te problem of calculating the intensity of the impulse. So are there any general advice? Or any ideas? Best practices?

• Initialize content of a jQuery remote tab on initial page load

  - by Carl

  I'm using the jQuery tabs library to create a set of remote (i.e., ajax loaded) tabs. However, to avoid the initial page load being empty until the ajax request finishes, I'd like to include the content for the initial tab with the initial page download. I've got this generally working by providing a div in the initial page load that matches the title of the tab, but even though this content appears immediately, as soon as I initialize the tabs it does the ajax request IN ADDITION which is both wasteful and causes a flicker. My basic question is how can I get jQuery tabs to NOT do an ajax request for the initially selected tab, and get this content as part of the initial page load, while still loading the other tabs dynamically. The complication is that I can't hard code the ids/hrefs for which tab is the "initial" one since the initial tab will change based on available content. I'm sure there is some kind of hacky way to do this with javascript rewriting the URLs of tabs dynamically before I initialize the tabs but I'm looking for a cleaner solution. Any ideas?

• Auto refresh web page

  - by Epitaph

  I have a web page which allows the user to carry out various operations that in turn modify the database. Also, this web application needs to keep track of various fields in database that keep changing with time. Is refreshing the page every few seconds the best possible way to implement this? For example, if there is a long list on the page requiring scrolling, it is hard to view the list since the page keeps resetting due to the refresh. I know, there are ways to retain the position of the scroll. But, could I use something more efficient?

• Displaying local images in the web browser control

  - by RichardK9

  Hi, I am writing a Windows Forms application and am creating a report for users to view in the webBrowser control. The problem is that it does not seem to display an image which is situated on my local hard drive, it just display the "broken image" red cross symbol. The path of the image is correct and when I view the source code of the generated html in either Firefox or Chrome it works but not in Internet Explorer (which I presume it what is used for this webBrowser control). Any help would be much appreciated. Thanks, Richard.

• How is Magento when it comes to adding custom functionality?

  - by ohsnapy

  hi, How is working with Magento when it comes to adding custom functionality? From an outsiders view the framework looks very complicated and it's hard to gage what is and is not possible. What are your experiences? Is it a difficult framework to get it to do what you want? Are there things that simply cannot be customized in Magento? How difficult is it to manage customizations when upgrading to latest versions,etc.. Any feedback/personal experiences would be great. Examples of highly customized Magento sites would be great too. Thanks for your help.

• Creating colour schemes based on an existing scheme

  - by Neil Barnwell

  I have a colour scheme based around yellow, for warning messages on a website. It amounts to a slightly orange bordered box, with a pale yellow fill. The exact colours are: #FED626 (border) #FFF7C0 (fill) I want to know if it's possible to convert this scheme mathematically or algorithmically somehow, to come up with a blue version where the border is the "same amount" of blue as this one is yellow. Is this possible, or do I just "pin the tail on the donkey" on a colour pallet to get roughly the right one? I ask, because I'd quite like to be able to calculate this on the fly, to perhaps implement something in .less. To give you an idea, I tried swopping the red and blue values on those two, and came up with this: #26D6FE (border) #C0F7FF (fill) That wasn't too hard, but think about if I wanted a pink colour scheme... :)

• VB.net Edit-And-Continue: ignore "unable to apply this change while debugging"

  - by FastAl

  When using VB.Net (2008) and paused in debugging, Edit-And-Continue is a great time-saver. However if you change any module/class-level information (variable, sub/function signature, etc), you get the error message like this: "unable to apply this change while debugging" While I can understand the technical challenge to making this work (and why it would be hard), it leaves me in a tight spot with just a few options: 1) Restart and recompile and get the program back to the same state 2) Continue debugging without making the change, and risk forgetting 3) Type up a reminder note to make the change All of which are annoying. Now I know that option '4) Just actually make the change' may not be possible. but does anybody know how to enable the following 'technically easy' possibility? 4) Let me change the code, get it flagged with the purple squiggly underline, so I can save it, but just ignore the change until recompile I have checked the Tools|options|debug|edit and continue, nothing appears to let me do this. thanks!

• Java program strange behavior, how to fix it ?

  - by Frank

  My notebook has Intel CPU, running Windows Vista. My program looks like this : public class Tool_Lib_Simple { public static void main(String[] args) { System.out.println("123"); } } When I run it, I expect to see : "123", but the output was : "Hi NM : How are you NM ?" which was the old output from two days ago before I changed my program. If I copy this program into another project in Netbean 6.7, it will run correctly and output "123", and if I change the program name from "Tool_Lib_Simple" to something else, it will also output "123", but just not under the name of "Tool_Lib_Simple" in the current project's src directory, I've deleted the "build" directory and did re-compile, re-build, it still gives me "Hi NM : How are you NM ?" as a result, seems to me the old version of my program is saved in the hard drive or ram and got stuck there, I've programmed many years, hardly ever encounter this kind of problem, how to fix this ?

• SSD and programming

  - by Simon Johnson

  I'm trying to put together a business case for getting every developer in our company an Intel SSD drive. The main codebase contains roughly 400,000 lines of code. My theory is that since the code is scattered about in maybe 1500 files, an SSD drive would be substantially faster for compiles. The logic being that many small reads really punishes the seak-time bottle-neck of a traditional hard-drive. Am I right? Is SSD worth the money in productivity gains by reducing the edit/compile cycle time?

• How to know what you don't know?

  - by Ivo Danihelka

  Is there a way how to recognize that you don't know something? For example, I had some hard realizations: I didn't know that criticism isn't a good way to teach your friends. I realized that after reading How to Win Friends & Influence People. I didn't know about the fundamental needed for an indutive bias in machine learning. If I have read Mitchell's Machine Learning book early, I would know it. I haven't found it mentioned in other books and papers. Sorry if the question is too generic. The question could also mean: How to know that you are missing something important about your programming language?

• Rake tasks in other files

  - by Arcath

  Im trying to use rake in a project, and if I put everything into Rakefile it will be huge and hard to read/find things, so I tried to stick each namesapce in its own file in lib/rake, i added this to the top of my rake file: Dir['#{File.dirname(__FILE__)}/lib/rake/*.rake'].map { |f| require f } it loads the file no problem, but doesn't have the tasks. I only have one .rake file as a test for now called "servers.rake" and it looks like this: namespace :server do task :test do puts "test" end end so when I run rake server:test id expect to see one line appear saying "test", instead I get rake aborted! Don't know how to build task 'server:test' at first I thought my codes wrong but if I copy the contents of lib/rake/servers.rake into Rakefile it works fine. How do I get rake tasks to work that are in another file?

• VS2010, VSS and post-commit hook?

  - by David Lively

  I'm using Visual Studio 2010 and VSS. Yes, I know VSS sucks. Hard. I'm attempting to force a move to TFS (since SVN integration with Expression and Sharepoint Designer is near impossible without forcing non-technical content managers to use TortoiseSVN), but that will not happen in the short term. I'm working with a local copy of the (classic ASP 3.0) site, and need to publish individual files to a web folder on our dev server whenever I check in a file so that the changes can be seen by other interested parties without having to publish from VSS. Does anyone know of a convenient way to add a post-commit script with VSS? It's acceptable for this script to run on my dev box (as opposed to the server), considering that VSS has no server to execute such actions.

• Apple has bigger market capitalization than Microsoft

  - by Paja

  Should I worry that my Microsoft programming skills (C#, .NET, WinAPI) will be obsolete in a few years, because everybody will be using Mac OS X, iPhone OS or some other Apple-originated OS? According to reuters, Apple has now bigger market capitalization than Microsoft. I know there is probably huge speculative bubble around Apple's shares, but just look at this graph (taken from business insider): I also know Windows have currently 90% of the OS market share, so we (Win devs) should be OK for a few years, but who knows, maybe in 10 years, it will be just 40%, and 0% on mobile phone OS market. Personally, I'm not much worried, because I think Microsoft will fight hard for their desktop OS market share, but I'm interested in your opinions.

• sql exception when transferring project from usb to c:\

  - by jello

  I'm working on a C# windows program with Visual Studio 2008. Usually, I work from school, directly on my usb drive. But when I copy the folder on my hard drive at home, an sql exception is unhandled whenever I try to write to the database. it is unhandled at the conn.Open(); line. here's the exception unhandled Database 'L:\system\project\the_project\the_project\bin\Debug\PatientMonitoringDatabase.mdf' already exists. Choose a different database name. Cannot attach the file 'C:\Documents and Settings\Administrator\My Documents\system\project\the_project\the_project\bin\Debug\PatientMonitoringDatabase.mdf' as database 'PatientMonitoringDatabase'. it's weird, because my connection string says |DataDirectory|, so it should work on any drive... here's my connection string: string connStr = "Data Source=.\\SQLEXPRESS;AttachDbFilename=|DataDirectory|\\PatientMonitoringDatabase.mdf; " + "Initial Catalog=PatientMonitoringDatabase; " + "Integrated Security=True"; what's going on here?

• What one-time-password devices are compatible with mod_authn_otp?

  - by netvope

  mod_authn_otp is an Apache web server module for two-factor authentication using one-time passwords (OTP) generated via the HOTP/OATH algorithm defined in RFC 4226. The developer's has listed only one compatible device (the Authenex's A-Key 3600) on their website. If a device is fully compliant with the standard, and it allows you to recover the token ID, it should work. However, without testing, it's hard to tell whether a device is fully compliant. Have you ever tried other devices (software or hardware) with mod_authn_otp (or other open source server-side OTP program)? If yes, please share your experience :)

• TabWidget Activity Handling - Does it Create a New Activity EVERY Time?

  - by stormin986

  When a TabWidget is using intents to designate the target Activity for each tab, is there any special handling of those Activities on the Activity Stack outside of the default operation? For Instance, if my app has tabs A, B, and C, and I click them in this order––A, B, A, C, A, B––how will the Activity stack change? My understanding of the default operation, if startActivity() is called each time on the intent, would have the Stack keep loading up new instances of the activities: A, AB, ABA, ABAC, ABACA, ABACAB It's hard to believe that's how it works though... Seems like it would be a waste of resources and could be endless. Can anyone tell me how this will actually work?

• Why is there no code-folding in emacs ?

  - by Pierre

  There are several questions on SO about how to get code folding in emacs, without having to add any special characters like "markers" in the comments for example. Someone said that there was "no perfect solution." It seems that it could be done by parsing the source of the program being written and look for matching parenthesis or bracket, or to do it based on indentation. You could also use a combination of scripts that use different methods. So why is it commonly accepted that there is no "perfect" and straightforward way to get code-folding in emac? Is there something in emacs or its architecture that makes it hard to program? If it were easy, after so many years of smart people using emacs you would think that someone would have wrote it.

• Create unordered list tree menu from data stored in an table with the adjacency list model...php

  - by Ronedog

  I need to create a tree menu of "nth" subcategories. I settled on using the adjacency list model for my table structure, because I won't be updating this table very much and this seemed the easiest to implement for my use. I want to style the output using "ul" and "li" tags...I already have a css and jquery solution to do the styling. My problem comes from pulling the data out of the database and using a recursive function via PHP to build the list ... the list is a concatenated string that gets parsed to build the tree. I'm really having a hard time getting the closing "ul" and "li" tags to line up just where they need to be. Is this the best way to do this? Are there other better ways using arrays or something like that to do this? Any examples you can point me to of "best practices" for building a list like this will be appreciated. Thanks.

• Session Variable Not Being Saved When Using Wizard Control ASP.NET

  - by davemackey

  I have a wizard control. When someone clicks a button within the wizard control I automatically advance to the next step (rather than forcing them to click next). However, this seems to cause the session state variable not to be saved. I've done some research and noticed that Response.Redirect does hard redirects that truncate page execution - and that you can add a false parameter to prevent this...what I'm wondering is if the wizard control is doing the same thing and if so, if I can add a parameter to this as well?

• Feeding a Drill Down Menu with categories, subcategories and subSubcategories from a database

  - by Hassan

  Hi everyone, I have a Drill Down menu and I want to have it gets its elements from a database, I am using php and MySQL and the table (categories) looks like this : http://yfrog.com/jctablehsj I can't figure out how I can extract these information in a way I could put it inside the Drill Down Menu ! I found the recursive method (with LEFT JOINs) and the nested method which I barely understood and again I couldn't apply it to the Drill Down Menu. I found that some people found out a solution with left join and group by but couldn't understand or copy their example ! I would be more than gratefull if you could give me the extact of the query. Thanks a lot for your hard work, Hassan

• Progressive Enhancement with box-shadow

  - by toby

  I would like to use WebKit's box-shadow css property for a little drop-down. The code would look like: .drop_down{ -webkit-box-shadow: 1px 1px 4px #888; box-shadow: 1px 1px 4px #888; } However, for browsers that do not have this capability, I would like to use borders to approximate this drop shadow, like so: .drop_down{ border-top: 1px solid #bbb; border-left: 1px solid #bbb; border-right: 2px solid #bbb; border-bottom: 2px solid #bbb; } The problem is, I don't want the border-based shadow to show up for the browsers that DO support box-shadow. I would like to avoid browser sniffing because I assume it's hard to cover all the cases. What is the simplest way to do this? I prefer a javascript-less solution, but I will consider simple javascript-based ones too.
