• unable to find an entry point named 'interlockedexchange'

  - by Miki Amit

  Hi , I built an application in c# vs2005 .net . Everything works fine when i run the application in win 32 bit, But when running the application in win 64 it crashes while trying to call the pinvoke interlockedexchange(which is within the kernel32.dll) function . This is the exception : unable to find an entry point named 'interlockedexchange' I didnt find the interlockedexchange function within the kernel32.dll under system32 directory but it was found under the syswow64 directory(in the kernel32.dll) . I guess that the .net runtime is configured to the system32 directory and not to the syswow64 . How is it possible to change this configuration ? Can you think of any other problem that could cause this? any help would be appreciated! thanks , Miki Amit

• jquery IE Fadein and Fadeout Opacity

  - by Tom

  Hi Guys, I am getting this weird problem in IE with a CSS Overlay I am applying for a lightbox. Basically, I use fadein and fadeout for jquery - the problem is that everything works fine EXCEPT in IE. In IE - I get no fadein - rather it just goes straight to opacity background. On fadeout - it removes the "opacity" for < 1 sec second and renders the page a "solid color" before removing the overlay. Anyone know how to fix this bug ? Its really annoying - I am using all the correct filters etc its just the fadein and fadeout in IE ? Thx

• Modifing settings in Django

  - by Cato Johnston

  I'm trying to get Django's manage.py to run with modified settings files. I have three settings files settings.py preview.py live.py settings.py contains my base settings but on live & preview sites I point the ['DJANGO_SETTINGS_MODULE'] to live or preview which in turn load the base file and any settings specific to that environment. This works fine, until I try to run migrations using manage.py I updated the manage.py file to import settings.preview but now when I try to run syncdb or migrate I get this error: django.core.exceptions.ImproperlyConfigured: You haven't set the DATABASE_ENGINE setting yet. My settings file has this in it though: DATABASE_ENGINE = 'mysql' How can I get this to work?

• Stop a stopwatch

  - by James Morgan

  I have the following code in a JPanel class which is added to a another class (JFrame). What I'm trying to implement is some sort of a stopwatch program. startBtn.addActionListener(new startListener()); class startListener implements ActionListener { public void actionPerformed(ActionEvent e) { Timer time = new Timer(); time.scheduleAtFixedRate(new Stopwatch(), 1000, 1000); } } This is another class which basically the task. public class Stopwatch extends TimerTask { private final double start = System.currentTimeMillis(); public void run() { double curr = System.currentTimeMillis(); System.out.println((curr - start) / 1000); } } The timer works fine and this is definitely far from complete but I'm not sure how to code the stop button which should stop the timer. Any advice on this? BTW I'm using java.util.timer

• Entity Framework Performance Inconsistency Compared to Sql Management Studio

  - by AndyV

  I'm getting timeouts with a very basic EF statement. I'm simply doing a select from a single table with a Entity.Title.StartsWith("test") and a .Take(25). When I run this for a search that returns no results I get a timeout. If I profile and grab the sql statement it looks fine, and if I run that sql in Management Studio it runs in a fraction of a second! Why would the same query run sub-second in Management Studio and timeout when generated by EF and called from an Asp.Net app?

• Autocomplete and Dynamic Parameter Passing

  - by abcParsing

  The code below works fine using jQuery UI 1.8 and jQuery 1.4.2 $("#sid_entry_box").autocomplete( {source:"autocomplete_sid.php?database="+database_name, minLength:4, delay:1000, enable:true, cacheLength:1 }); The database name is passed as a get parameter of the php call. In this application, I have two databases selected by a radio button. Since jQuery loads and assigns this function when the document is loaded, the database name is whatever was checked at that momemnt. What I really need to pass to the php call is the following: database=$("input[name=rf_database_option]:checked").val(); Is ther ean easy to understand way to be able to pass a dynamic dom value?

• [Ruby] Why do I have to URI.encode even safe characters for Net::HTTP requests?

  - by Matthias

  I was trying to send a GET request to Twitter (user ID replaced for privacy reasons) using Net::HTTP: url = URI.parse("http://api.twitter.com/1/friends/ids.json?user_id=12345") resp = Net::HTTP.get_response(url) this throws an exception in Net::HTTP: NoMethodError: undefined method empty?' for #<URI::HTTP:0x59f5c04> from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/net/http.rb:1470:ininitialize' just by coincidence, I stumbled upon a similar code snippet, which used URI.encode prior to URI.parse, so I copied that and tried again: url = URI.parse(URI.encode("http://api.twitter.com/1/friends/ids.json?user_id=12345")) resp = Net::HTTP.get_response(url) now it works fine, but why? There are no reserved characters that need escaping in the URL I mentioned, so why do I have to call URI.encode for get_response to succeed?

• LNK1106 with big binary resource

  - by E Dominique

  I have a rather huge .dat-file (896MB) included as a BIN resource in my project. Now I get a LNK1106 link error ("fatal error LNK1106: invalid file or disk full: cannot seek to 0x382A3920".) I use Visual Studio 2005 under Windows XP, and have tried on a 4GB RAM machine with high Virtual Memory settings and lots of disk space. I have tried a number of different optimization flags, but to no avail. Does anyone have a clue? EDIT: I have narrowed it down to a specific size of the compiled resource. If the .res file is 544078588 bytes (about 518.9MB) or larger, the error occurs. If it is smaller it works just fine. Still no solution, though...

• All comments get marked as spam regardless (Wordpress MU)

  - by meds

  Everyone (besides me) who comments on another persons blog gets marked as spam when they comment on other peoples blogs. When they comment on their own its fine. Might be related, I've installed reCaptcha and have disabled it for logged in users yet everyone who is logged in still sees it, I don't, and incidentally my comments don't get marked as spam. I don't have akismet or hashcash or any other form of spam filtering turned out (with the exception of super captcha for registration). Any idea what's wrong or where I should look first?

• Custom flash mp3 player stopping in the middle of playing audio on windows nt ie6 system

  - by Charlotte Moller

  We have used a custom MP3 flash player for a lot of years on our website without any issues, but recently, a client of ours is reporting that the audio is playing for several seconds and then stopping. When they refresh the page or click play in the player again the audio plays fine. We are puzzled as to what could be causing this issue after this running successfully for our clients for so many years. The client system is Windows NT running IE6. Does anyone have any idea what could cause the audio to behave this way? Could audio drivers or the version of flash cause problems? We do not have flash programmers on our team so we are not even sure where to start looking within the flash code of the player. Any ideas?

• authlogic auto_register feature using my options

  - by holden

  I have auto registration working with authlogic using gaizka's version of authlogic_openid which I found on Github since pelle's original addition of the feature seemed to cause issues. http://github.com/gaizka/authlogic%5Fopenid http://stackoverflow.com/questions/1476953/using-authlogic-to-auto-create-users-bypassing-explicit-user-registeration This one works fine however when using the auto_register feature it ignores my options for authlogic such as retrieving the email from the openid provider... any ideas what I'm doing wrong? Hhere's the example: http://big-glow-mama.heroku.com/ http://github.com/holden/authlogic_openid_selector_example/tree/with-facebook/ You can see the difference if you register vs. login... #user.rb class User < ActiveRecord::Base acts_as_authentic do |c| c.validate_login_field = false # optional, but if a user registers by openid, he should at least share his email-address with the app c.validate_email_field = false # fetch email by ax c.openid_required_fields = [:email,"http://axschema.org/contact/email"] #c.required_fields = ["http://axschema.org/contact/email"] # fetch email by sreg #c.optional_fields = ["email"] end #private method to deal with emails goes here end #UserSession.rb class UserSession < Authlogic::Session::Base auto_register logout_on_timeout true end

• Maven: How to create assembly with snapshot artifacts without timestamps file name?

  - by marabol

  I've a repository containing snapshot artifacts with timestamps. I want to create an assembly, that contains the dependencies. This works fine. But the artifact names contains the timestamp. So i wonder how to remove the timestamp from filename for the assembly only. I've used this dependencySet: <outputFileNameMapping>${artifact.artifactId}-${artifact.version}.${artifact.extension}</outputFileNameMapping> But version seams to contain already the timestamp. So is there any chance to get a 1.1.1-SNAPSHOT instead of 1.1.1-20100323.071348-182?

• Document.ready() failing on popup

  - by Seth Duncan

  I am using ASP.Net and jQuery/jQuery UI and I am trying to use the datepicker control. It works fine on every page, except when I have to use the popup (to add new data into the database and then i refresh the current page to reflect the new data being entered). It seems that document.ready() is failing when I use the popup. I can invoke the datepicker control manually with adding a click event to fire off the showcalendar function, however I want to try and make it work. Does anyone have any ideas of why a popup would fail document.ready() ? Thanks!

• Strange behavior of I() in left-/right-hand side of formula

  - by adibender

  set.seed(98234) y <- rnorm(100) x <- rnorm(100) lm0 <- lm(y ~ x) lm1 <- lm(I(y) ~ I(x)) all work perfectly fine and I guess we can agree that ´lm0´ is what one would expect to happen. lm1 is equal to lm0 (judging by coefficients). So are set.seed(98234) lm3 <- lm(I(rnorm(100)) ~ rnorm(100)) set.seed(98234) lm4 <- lm(rnorm(100) ~ I(rnorm(100))) But when I() is on neither or both sides of the formula I don't get the results from above: set.seed(98234) lm2 <- lm(I(rnorm(100)) ~ I(rnorm(100))) set.seed(98234) lm5 <- lm(rnorm(100) ~ rnorm(100)) Any ideas why?

• Haskell: type inference and function composition

  - by Pillsy

  This question was inspired by this answer to another question, indicating that you can remove every occurrence of an element from a list using a function defined as: removeall = filter . (/=) Working it out with pencil and paper from the types of filter, (/=) and (.), the function has a type of removeall :: (Eq a) => a -> [a] -> [a] which is exactly what you'd expect based on its contract. However, with GHCi 6.6, I get gchi> :t removeall removeall :: Integer -> [Integer] -> [Integer] unless I specify the type explicitly (in which case it works fine). Why is Haskell inferring such a specific type for the function?

• Is there "native" support for JSON in JDK6 Script Engine?

  - by Ayman

  I'm using JDK6the standard Scripting. I need to store and retrieve some JavaScript Objects that also contain Java Objects to JSON. I loaded the json2.js into the ScriptENgine and can use it fine without issue if the objects are all created in the Scrip Engine. The moment I try to use my own Java classes, I get some errors like "object does not support toJSON" errors. I did not find much about JSON in Java Scripting / Rhino context. Am I doing something totally wrong? What's the best way of achieving the requirement?

• Cstom handler on IIS 7.5 doesn't work

  - by Amit

  Hi, I am new to IIS 7.5. I have an application in asp.net 2.0, which has its own custom URL rewriting mechanism. All the requests on the browser with .htm will be mapped to .aspx. It works fine on IIS 6, but somehow I could not get it working on IIS 7.5. On IIS 6, I go to Application PropertiesConfigurationMappings and add a new extension .htm with the executable as aspnet_isapi.dll On IIS 7.5 i added a handler mapping, with path as .htm and executable as aspnet_ispai.dll But the request does not even come to global.asax. If i try the URL with .aspx extension, pages load properly. Any idea how to set up custom mappings in iis 7.5?

• How to fix weird scrolling/alignment behavior when using keyboard in MenuStrip?

  - by bentsai

  I started noticing strange behavior when navigating the main toolbar of my Winforms application, and I don't know how to fix it. When I initially open the dropdown of the File menu, it looks like this: I begin to scroll down each item with the arrow keys, and everything is fine until I reach "Exit". As soon as I hit the down arrow key from "Log Off", or if I hit the up arrow key from "Open", the menu rearranges itself to look like this: I'm puzzled by this behavior. The menu still works, and from this point, if I start scrolling up, I can get the arrangement back to normal: A few observations: The menu still works. This doesn't happen when using the mouse. I have some code that toggles the Visible property of some of the menu items. I was able to modify what the arrangement was by playing around with this, but it was still messed up. Can anyone help me understand what is going on, and how to fix it?

• "The left hand side of an assignment must be a variable" due to extra parentheses

  - by polygenelubricants

  I know why the following code doesn't compile: public class Main { public static void main(String args[]) { main((null)); // this is fine! (main(null)); // this is NOT! } } What I'm wondering is why my compiler (javac 1.6.0_17, Windows version) is complaining "The left hand side of an assignment must be a variable". I'd expect something like "Don't put parentheses around a method invokation, dummy!", instead. So why is the compiler making a totally unhelpful complaint about something that is blatantly irrelevant? Is this the result of an ambiguity in the grammar? A bug in the compiler? If it's the former, could you design a language such that a compiler would never be so off-base about a syntax error like this?
