• How to include NetBeans Platform Source code into module dependencies

  - by Ben Hammond

  I am debugging a NetBeans Platform application. I have downloaded the NetBeans Platform source code .zip file. I would really really like to attach the source code to the debugger so that I can seamlessly jump to internal NB source code. Normally I would edit the Library configuration to tell NB where to find the source code, and it would just work. However this is not possible for NetBeans Modules; when I look at the Utilities API module dependency it does not look like a normal NB library and there is nowhere to add in the source code. I suspect that if I were to rebuild my project using Maven this would work automatically. But thats a terrible reason to switch to maven. How can I get the NB Platform Source code included into my Module Dependencies ?

• DLL with JNA error looking up function?

  - by Thomas Nappo

  This is the code in my DLL (C#): http://pastebin.com/Uirn0z2V I have the DLL built and inside both the JDK bin folder along with inside my project. This is the Java code I am using to access with JNA: http://pastebin.com/NffpaEp8 Yet when I run my Java code this happens: Exception in thread "main" java.lang.UnsatisfiedLinkError: Error looking up function 'Run': The specified procedure could not be found. at com.sun.jna.Function.<init>(Function.java:179) at com.sun.jna.NativeLibrary.getFunction(NativeLibrary.java:391) at com.sun.jna.NativeLibrary.getFunction(NativeLibrary.java:371) at com.sun.jna.Library$Handler.invoke(Library.java:205) at $Proxy0.Run(Unknown Source) at RunPETest.main(RunPETest.java:18) I have no experience with using JNA with custom DLLs or creating DLLs with C#... so I'm stuck here.

• Choosing between YUI Charts or Google Visualization API

  - by r2b2

  Hello , I'm a bit stuck with which charting library I will use in my project. Im stuck with this two (but also open for other suggestions) For YUI Charts : Pro : - Very robust and configurable Cons : - Uses flash 9 , which might potentially be inaccessible for users without up to date flash version - Does not support export to image (for flash versions < 10 only) For Google Visualization API pros: - small file size for the libraries, - can be exported to static image charts (via separate API call) Cons - limited configuration options So there, please help me decide. YUI charts has the edge over configuration options but Google Visualization API has the edge in terms of accessibility as it uses SVG to render the grapsh instead of Flash. For users that are hand-cuffed by corporate IT prohibitions , they cant just upgrade their Flash version and the page will not work. Thanks!

• How do you fix the Silverlight application shift that occurs in the Firefox browser?

  - by Roy

  Hi, Currently I have an Silverlight application that when run on Firefox browser (ver 3.6) the entire contents of the Silverlight application shifts a little, and also the scrollbars on both the bottom and the side appear when I first use it. This does not happen in IE 8. How can I fix this in Firefox so it doesn't happen? The project type I created was the "Silverlight 3 Application + Website" via Expression Blend 3. This the code I am using in my MainPage.xaml: <UserControl xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Class="StackoverflowExample.MainPage" Width="640" Height="480"> <Grid x:Name="LayoutRoot" Background="Green"> <Rectangle Fill="#FFBB2020" Stroke="Black" Margin="155,58,266,178"/> <Button Margin="199,180,302,236" Content="Button"/> </Grid> </UserControl>

• Jquery: How can I place triggers on images already cached?

  - by FLX

  Please see: hxxp://flx.me/h/0504/ Source: hxxp://pastebin.com/bDh5k3Qd jquery.preload-min.js: hxxp://jquery.com/plugins/project/Preload jquery.jplayer.min.js: hxxp://www.happyworm.com/jquery/jplayer/0.2.4/developer-guide.htm I'm using jquery.preload-min.js to preload images and to send a play trigger to jquery.jplayer.min.js to start playing a mp3 file. This works great when viewing the page for the first time (or force reloading all content). However, when the image has already been cached, it doesn't use the preloading script and thus does not send the play trigger to jplayer. How can I make it send a play trigger even when the image is cached? Thank you in advance, Dennis

• Converting a jQuery plugin to work on all objects, not just the DOM

  - by Jon Winstanley

  I am using the jQuery physics plugin for a pet project I am working on. The plugin enables the moving of DOM objects in realistic ways using velocity, gravity, wind etc. However I want to use the plugin to calculate where objects are to be placed inside a canvas element, not DOM object. How do I change the plugin script to work for ANY object with 'top' and 'left' properties rather than only working with DOM objects found with a jQuery selector? Currently the script functions look like this: jQuery.fn.funname = function() { return this; };

• iphone Memory gets freed in debug mode but not in release mode

  - by gdr

  I have been testing my iPhone debug build on both my device and simulator with activity monitor, leaks, and object allocations. The code is pretty well optimized so I have decided to test the release build. I went into the project Menu and set the target build to be release, I then added the necessary header paths that my app is using to the headers search paths and ran the release build on the device with the above mentioned instruments. What I have noticed now is that memory that was freed when I used the debug build does not get freed when using release version. There is one place in my App that I remove a scroll view with some images which frees up a significant amount of memory when I use the debug build, but no memory is freed up in that place when I use the release version. Does someone have any ideas where I need to start looking at? did I setup my release build wrong?

• Recommended way to manage persistent PHP script processes?

  - by BigglesZX

  First off - hello, this is my first Stack Overflow question so I'll try my best to communicate properly. The title of my question may be a bit ambiguous so let me expand upon it immediately: I'm planning a project which involves taking data inputs from several "streaming" APIs, Twitter being one example. I've got a basic script coded up in PHP which runs indefinitely from the command line, taking input from the Twitter streaming API and doing very basic things with it. My eventual objective is to have several such processes running (perhaps daemonized using the System Daemon PEAR class), and I would like to be able to manage them from some governing process (also a PHP script). By manage I mean basic operations such as stop/start and (most crucially) automatically restarting a process that crashes. I would appreciate any pointers on how best to approach this process management angle. Again, apologies if this question is too expansive - tips on more tightly focused lines of enquiry would be appreciated if necessary. Thanks for reading and I look forward to your answers.

• English dictionary as txt or xml file with support of synonyms

  - by Simon

  Can someone point me to where I can download English dictionary as a txt or xml file. I am building a simple app for myself and looking for something what I could start using immediately without learning complex API. Support for synonyms would be great, that is it should be easier to retrieve all the synonyms for particular word. It would be absolutely fantastic if dictionary would be listing British and American spelling of the words where they are differ. Even if it would be small dictionary (few 000's words) that's ok, I only need it for small project. I even would be willing to buy one if the price is reasonable, and dictionary is easy to use - simple xml wold be great. Any directions please.

• Numerical Pattern Matching

  - by Timothy Strimple

  A project I'm researching requires some numerical pattern matching. My searches haven't turned up many relevant hits since most results tend to be around text pattern matching. The idea is we'll have certain wave patterns we'll need to be watching for and trying to match incoming data vs the wave database we will be building. Here is and example of one of the wave patterns we'll need to be matching against. There is clearly a pattern there, but the peaks will not have the exact same values, but the overall shape of the wave iterations will be very similar. Does anyone have any advice on how to go about storing and later matching these patterns, and / or other search terms I can use to find more information on the subject of pattern matching? Thanks, Tim.

• Open source political campaign management software?

  - by carolclarinet

  Does anyone know of any active open source projects working on political campaign management software? I looked on sourceforge but didn't see anything relevant from the queries "political", "politics", "donations", "campaign", or in the categories "accounting", "politics" or "voting". I'm involved with a political campaign that is currently paying out the nose for some horribly designed SaaS (whose Name i Guess i should Protect, ahem) to basically just keep track of donations people have made now, donations people have made in the past, donations people have pledged to make, contact information, the way they will likely vote, etc. It's a bit much to manage in spreadsheets, but doesn't seem like it's something complex enough that political campaigns should have to pay for (especially low-budget local ones). I'd love to help out if such a project exists, or start/revive one if it doesn't. Any hints, places to look, etc are much appreciated.

• UITextView like iPhone Notes application

  - by Mark

  I am trying to recreate the Notes application. So far I got the following: textView = [[UITextView alloc] initWithFrame:CGRectMake(25.0, 30.0, 295.0, 214.0)]; textView.delegate = self; textView.backgroundColor = [UIColor clearColor]; textView.font = [UIFont fontWithName:@"MarkerFelt-Thin" size:19.0]; [self.view addSubview:textView]; The thing I dont know is how they were able to put the date on top like a header (it is within the UIScrollView that is obvious). Also under every text there is a line where did that came from. Does someone have an idea or a sample project I can take a look at?

• In Elixir or SQLAlchemy, is there a way to also store a comment for a/each field in my entities?

  - by kchau

  Our project is basically a web interface to several systems of record. We have many tables mapped, and the names of each column aren't as well named and intuitive as we'd like... The users would like to know what data fields are available (i.e. what's been mapped from the database). But, it's pointless to just give them column names like: USER_REF1, USER_REF2, etc. So, I was wondering, is there a way to provide a comment in the declaration of my field? E.g. class SegregationCode(Entity): using_options(tablename="SEGREGATION_CODES") segCode = Field(String(20), colname="CODE", ... primary_key=True) #Have a comment attr too? If not, any suggestions?

• Strange execution of get accesor in c#?

  - by Kenji Kina

  I set up a simple program just to test how the code inside a get accessor executes (since I had been having some issues in another project), and found something quite strange: class Program { static void Main(string[] args) { var test = new TestClass(); var testBool = test.TestBool; } } public class TestClass { private bool _testBool = true; public bool TestBool { get { if (_testBool) { Console.WriteLine("true!"); } else { Console.WriteLine("false! WTF!"); } _testBool = false; return _testBool; } } } I expected the output to be true! But what I got instead was true! false! WTF! Just what is going on here?

• Programming against WSDL without access to actual webservice

  - by Frode Lillerud

  I'm going to use C# to read data from a few webservices. I've done that many times before, but those times I've had direct access to the webservices from my development machine. In this project I've just been sent a .wsdl file, and a couple of .xsd files for the webservice they have in their local intranet. I've seen that I can use "Add Web Reference", and point directly to the .wsdl file, so that a C# class is created. But how can I really test it? I'd like to return some dummy data that I can visualize while I develop. Any tips for this situation?

• SQL Server 2008 automated database drop, create and fill

  - by lox

  For the database in my project I have a drop/create script for the database, a script for creating tables and SPs and an Access 2003 .mdb file with some exported values. To set up the database from scratch I can use my SQL management studio to first run one script, then the other and lastly manually run the sort of tedious import task. But I would like to do this as automated as possible. Hopefully something like putting the three files in a folder along with a fourth script to execute. Looking something like: run script "dropcreate.sql" run script "createtables.sql" import "values.mdb" How is this done? I hope to avoid using SSIS and the like. The tricky this is of course the import of data, where I can't seem to find a simple way. It is also important that the files a left as they are and not embedded into anything.

• Building Android app from ant via Hudson - chicken and egg problem

  - by Eno

  When using an Android-generated ant build file, the file references your SDK installation via an sdk.dir property inside the local.properties files which is generated by "android update project -p .". The comments in build.xml suggest that local.properties should NOT be checked into version control. BUT, when you run your build from Hudson, it does a fresh checkout of your code from version control, hence local.properties does not exist and subsequently the build fails without sdk.dir being set. So its kind of chicken and egg problem. As a workaround I have checked local.properties into version control for now (nobody else will use it) but I was curious as to how other developers had tackled this problem ?

• How do I mock a custom field that is deleted so that south migrations run?

  - by muhuk

  I have removed an app that contained a couple of custom fields from my project. Now when I try to run my migrations I get ImportError, naturally. These fields were very basic customizations like below: from django.db.models.fields import IntegerField class SomeField(IntegerField): def get_internal_type(self): return "SomeField" def db_type(self, connectio=None): return 'integer' def clean(self, value): # some custom cleanup pass So, none of them contain any database level customizations. When I removed this code, I've created migrations so the subsequent migration all ran fine. But when I try to run them on a pre-deletion database I realized my mistake. I can re-create a bare-bones app and make these imports work, but Ideally I would like to know if South has a mechanism to resolve these issues? Or is there any best practises? It would be cool if I could solve these issues just by modifying my migrations and not touching the codebase. (Django 1.3, South 0.7.3)

• How can I build a Truth Table Generator?

  - by KingNestor

  I'm looking to write a Truth Table Generator as a personal project. There are several web-based online ones here and here. (Example screenshot of an existing Truth Table Generator) I have the following questions: How should I go about parsing expressions like: ((P = Q) & (Q = R)) = (P = R) Should I use a parser generator like ANTLr or YACC, or use straight regular expressions? Once I have the expression parsed, how should I go about generating the truth table? Each section of the expression needs to be divided up into its smallest components and re-built from the left side of the table to the right. How would I evaluate something like that? Can anyone provide me with tips concerning the parsing of these arbitrary expressions and eventually evaluating the parsed expression?
