  • use boolean with visible, as3

    - by VideoDnd
    Is there a better way to do use a use a boolean with visible? This animation blinks 30 times and stops. It works without error, but takes a moment to load. I would like to learn other ways of using visibility with conditionals. var timz:Timer = new Timer(100,30); timz.addEventListener(TimerEvent.TIMER, doIt); var condition:Number = 5; function doIt(event:TimerEvent):void{ trace("fire!"); if(condition=5){ box.visible = !box.visible; } } timz.start();

  • How do I enable automatic reloading of view files in development mode in JRuby on Rails?

    - by thekingoftruth
    I am developing an app in JRuby on Rails. For some reason, when I edit the view files, the development JRuby Mongrel server doesn't reload them. The perplexing thing is that after editing the controller files, the server reloads them just fine on the next request. This would be annoying even when using MRI Ruby, however starting up JRuby Mongrel after every view edit is much slower, and much more annoying. (Note that once it starts up it's quite fast, the only issue is startup--the JVM has to load up every time I start JRuby Mongrel.) I'm running JRuby 1.5.0, Rails 2.3.5, and Java 6.

  • How to determine if birthday or anniversary occured during date range

    - by davekaro
    Given I have a birthday/anniversary DateTime, how can I determine if that date occurred during a specific date range? For example, Birthday = 1/2/2000 Date Range = 12/25/2008 - 1/3/2009 I need a method to determine whether or not this person's birthday happened during that date range - preferably in C#. I first went about changing the year of the birthday DateTime to match the date range, then just check if the "new" birthday DateTime is between the start and end date of the date range... but when the date range spans different years, like in my example above - I had to add a nasty if statement. Is there no better way?

  • fortran error I/O

    - by jpcgandre
    I get this error when compiling: forrtl: severe (256): unformatted I/O to unit open for formatted transfers, unit 27, file C:\Abaqus_JOBS\w.txt The error occurs in the beginning of the analysis. At the start, the file w.txt is created but is empty. The error may be related to the fact that I want to read from an empty file. My code is: OPEN(27, FILE = "C:/Abaqus_JOBS/w.txt", status = "UNKNOWN") READ(27, *, iostat=stat) w IF (stat .NE. 0) CALL del_file(27, stat) SUBROUTINE del_file(uFile, stat) IMPLICIT NONE INTEGER uFile, stat C If the unit is not open, stat will be non-zero CLOSE(unit=uFile, status='delete', iostat=stat) END SUBROUTINE Ref: Close multiple files If you agree with my opion about the cause of the error, is there a way to solve it? Thanks

  • How to deploy a c# application while including third party DLL's?

    - by Willem
    To start with, I don't know much of deployment. I hope my question makes sense. I need to install/deploy a c# application to a number of desktops. It needs a third-party DLL : a c++ library ("lpsolve55.dll", for those interested, it is a free MIP/LP solver, see lpsolve.sourceforge.net/5.5/). I use it in my code in the following way: [DllImport("lpsolve55.dll", SetLastError = true)] public static extern bool add_column(int lp, double[] column); For testing, I have manually copied the .dll file to to project\bin\release, it works fine. My question: I will need an installer for the application, which will manage that the .dll will install as well. I am considering clickonce deployment since I am using visual studio express (2008), but any not too expensive solution will do. What would you advice?

  • What are the pro and cons of having localization files vs hard coded variables in source code?

    - by corgrath
    Definitions: Files: Having the localization phrases stored in a physical file that gets read at application start-up and the phrases are stored in the memory to be accessed via util-methods. The phrases are stored in key-value format. One file per language. Variables: The localization texts are stored as hard code variables in the application's source code. The variables are complex data types and depending on the current language, the appropriate phrase is returned. Background: The application is a Java Servlet and the developers use Eclipse as their primary IDE. Some brief pro and cons: Since Eclipse is use, tracking and finding unused localizations are easier when they are saved as variables, compared to having them in a file. However the application's source code becomes bigger and bloated. What are the pro and cons of having localization text in files versus hard coded varibles in source code? What do you do and why?

  • Custom annotations to configure tests

    - by ace
    First of al let me start off by saying I think custom annotations can be used for this but i'm not totally sure. I would like to have a set of annotations that I can decorate some test classes with. The annotations would allow me to configure the test for different environments. Example: public class Atest extends BaseTest{ private String env; @Login(environment=env) public void testLogin(){ //do something } @SignUp(environment=env) public void testSignUp(){ //do something } } The idea here would be that the login annotation would then be used to lookup the username and password to be used in the testLogin method for testing a login process for a particular environment. So my question(s) is this possible to do with annotations? If so I have not been able to find a decent howto online to do something like this. Everything out there seems to be your basic here's how to do your custom annotations and a basic processor but I haven't found anything for a situation like this. Ideas?

  • platform independent and open source

    - by Lukas Schmelzeisen
    Hey, OK i want to start writing platform independent and open source code (mostly C++). What do i have to consider when doing so? Stop using IDEs and better use makefiles from now on? What do all the "professional" open source coders do (like the guys behind GNU) and what tools do they use? I'm special interested into developing shared libraries. How do you get the cross platform (so working as ".so" on Linux and as ".dll" on Windows)? I'm working on Windows so I'm not that much into all the Linux tools and words, are there good tools to get the same result on Windows as on ?Linux Thanks

  • svn working copy spanning 2 physical drives?

    - by ronenosity
    I have a large repository hosted on dreamhost that I backup daily on a remote machine using a windows scheduled task which updates the working copy located on an external USB 300GB drive connected to the remote machine. The 300GB drive is nearly full with only 26GB of free space remaining. Recently I added a second USB external 1TB drive to increase storage capacity. I would like to ask: what is the best way to use the new 1TB drive? Is it possible to span the working copy across both drives (ex: somehow create a 1.3 TB drive)? If I copied the working copy from the 300GB to the 1TB would svn continue form do I need to retarget the update working copy script to the new 1TB drive and start downloading everything again (least desired option) thanks

  • Shell script for testing

    - by Helltone
    I want a simple testing shell script that launches a program N times in parallel, and saves each different output to a different file. I have made a start that launches the program in parallel and saves the output, but how can I keep only the outputs that are different? Also how can I actually make the echo DONE! indicate the end? #!/bin/bash N=10 for((i=1; j<=$N; ++i)); do ./test > output-$N & done echo DONE!

  • How do I compile for windows XP under windows 7 / visual studio 2008

    - by Jon Cage
    I'm running Windows 7 and Visual Studio 2008 Pro and trying to get my application to work on Windows XP SP3. It's a really minimal command line program so should have any ridiculous dependencies: // XPBuild.cpp : Defines the entry point for the console application. // #include "stdafx.h" int _tmain(int argc, _TCHAR* argv[]) { printf("Hello world"); getchar(); return 0; } I read somewhere that defining several constants such as WINVER should allow me to compile for other platforms. I've tried the added the following to my /D compiler options: ;WINVER=0x0501;_WIN32_WINNT 0x0501;NTDDI_VERSION=NTDDI_WINXP But that made no difference. When I run it on my Windows XP machine (actually running in a virtualbox) I get the following error: This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem. So what have I missed? Is there something else required to run MSVC compiled programs or a different compiler option or something else?

  • Flex 3 Regular Expression Problem

    - by Tommy
    I've written a url validator for a project I am working on. For my requirements it works great, except when the last part for the url goes longer than 22 characters it breaks. My expression: /((https?):\/\/)([^\s.]+.)+([^\s.]+)(:\d+\/\S+)/i It expects input that looks like "http(s)://hostname:port/location". When I give it the input: https://demo10:443/111112222233333444445 it works, but if I pass the input https://demo10:443/1111122222333334444455 it breaks. You can test it out easily at http://ryanswanson.com/regexp/#start. Oddly, I can't reproduce the problem with just the relevant (I would think) part /(:\d+\/\S+)/i. I can have as many characters after the required / and it works great. Any ideas or known bugs?

  • How to write a custom (odd) authentication plugins for Wordpress, Joomla and MediaWiki

    - by Bart van Heukelom
    On our network (a group of related websites - not a LAN) we have a common authentication system which works like this: On a network site ("consumer") the user clicks on a login link This redirects the user to a login page on our auth system ("RAS"). Upon successful login the user is directed back to the consumer site. Extra data is passed in the query string. This extra data does not include any information about the user yet. The consumer site's backend contacts RAS to get the information about the logged in user. So as you can see, the consumer site knows nothing about the authentication method. It doesn't know if it's by username/password, fingerprint, smartcard, or winning a game of poker. This is the main problem I'm encountering when trying to find out how I could write custom authentication plugins for these packages, acting as consumer sites: Wordpress Joomla MediaWiki For example Joomla offers a pretty simple auth plugin system, but it depends on a username/password entered on the Joomla site. Any hints on where to start?

  • Queue remote calls to a Python Twisted perspective broker?

    - by agartland
    The strength of Twisted (for python) is its asynchronous framework (I think). I've written an image processing server that takes requests via Perspective Broker. It works great as long as I feed it less than a couple hundred images at a time. However, sometimes it gets spiked with hundreds of images at virtually the same time. Because it tries to process them all concurrently the server crashes. As a solution I'd like to queue up the remote_calls on the server so that it only processes ~100 images at a time. It seems like this might be something that Twisted already does, but I can't seem to find it. Any ideas on how to start implementing this? A point in the right direction? Thanks!

  • Style of if: to nest or not to nest

    - by Marco
    A colleague of mine and me had a discussion about the following best-practice issue. Most functions/methods start with some parameter checking. I advocate the following style, which avoids nesting. if (parameter one is ugly) return ERROR; if (parameter two is nonsense || it is raining) return ERROR; // do the useful stuff return result; He, who comes from a more functional/logic programming background, prefers the following, because it reduces the number of exit points from the function. if (parameter one is ok) { if (parameter two is ok && the sun is shining) { // do the useful stuff return result } } return ERROR; Which one would you prefer and why?

  • Suggest resources for learning Scheme.

    - by EmFi
    I'll be starting a new job soon where Scheme is heavily used. I currently do not know Scheme, but my employer assures me that is not a problem. Regardless I'd like to hit the ground running and have a working knowledge of the language before my start date. So I'm looking for good resources from which to learn Scheme. I have had minimal exposure to functional languages. Really only a small chunk of a course devoted to Haskell. But I have a strong background in procedural and OO and procedural languages. Before it gets requested by a commenter, I am competent with the following languages: C, C++, C#, Java, Perl, Python, and Ruby.

  • Naming suggestions for a function returning parent prototype

    - by hevalbaranov
    I'm having a naming trouble with a function which returns parent prototype of specified object. It's being used like this: # Pseudo Code MyClass { super(MyClass,this).constructor.call(.... The problem is that I want to use a word which is as superior as "super", but "super" is reserved even it's undefined. Now I'm using "parent", but the window object has a property named parent. I hate Javascript. What should I name this function? Names have to start with lowercase and have to be short.

  • Proper abstraction of the database tier in a 3 tier system?

    - by Earlz
    Hello, I am creating a 3 tier application. Basically it goes Client - (through optional server to be a thin-client) - Business Logic - Database Layer And basically making it so that there is never any skipping around. As such, I want for all of the SQL queries and such to be in the Database Layer. Well, now I'm a bit confused. I made a few static classes to start off the database tier but what should I do for the database connections? Should I just create a new database connection anytime I enter the Database Layer or would that be wasteful? Does Connection.Open() take time whenever you have a ConnectionPool? To me, it just feels wrong for the Business tier to have to pass in a IdbConnection object to the Database tier. It seems like the Database tier should handle all of that DB-specific code. What do you think? How can I do it the proper way while staying practical?

  • long running process in asp.net C#

    - by user339323
    Hello All, I have a web application that has a long running (resource intensive) process in the code behind and the end output is a pdf file (images to pdf conversion tool) It runs fine..and since I am on a dedicated server, it is not at all a problem with respect to resources right now. However, I wonder that the system would reach its resource limits if, there are more than 20 users processing at a time. I have seen services online where the user enters their email and the processes are, I suppose, queued in the background and the results emailed with the 1st in 1st out method. Can someone please give me a start on how to implement this kind of logic in asp.net applications using C#? Thanks a lot in advance, Prasad.

  • Seam-gen isn't working properly.. log4j acuses an error

    - by rgoytacaz
    Hello Seam Users, I'm having a couple problems with my Seam start up. I did the ./seam generate to reverse my current postgres db, which contains 4 tables, first I though everything was okay, just a warning message, but when I imported the project into eclipse, I saw that none of my packages had any class. This is the error that seam generate, got me. [hibernate] Executing Hibernate Tool with a JDBC Configuration (for reverse engineering) [hibernate] 1. task: hbm2java (Generates a set of .java files) [hibernate] log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment). [hibernate] log4j:WARN Please initialize the log4j system properly. [javaformatter] Java formatting of 0 files completed. Skipped 0 file(s). Any ideas? The seam-gen was supposed to generate some entity classes, but its not. I suppose that error is causing the mis-behavior. Regards

  • Two CVS projects into one SVN project

    - by komunca
    I have two CVS projects, which I maintain in Eclipse. I check out first project, and for second project I use "checkout in existing project" option, so I'm able to maintain two CVS projects into one Eclipse project. Doing this I'm able to Tag both projects with the same tag,etc. And know, time has come to start using SVN. I was able to create two separate CVS dump files, and when I used svnadmin to load then into SVN repository, I wasn't able to keep the structure I had in CVS! So, when i import both dump seperatly into SVN I get the following structure: ProjA - brancher tags trunk ProjB bracnches tags trunk In CVS I was able to have ProjB as a child folder of the ProjA trunk! Is there any way to implement this using SVN?

  • Book recommendation for a Ruby dev learning Java

    - by cpjolicoeur
    I've been a Ruby developer for the past 4-5 years, and prior to that coded in Perl and a language called ProvideX for years. As hard as it may seem, I've never written a Java application short of the basic Hello World app probably a decade ago. I'm beginning to start doing some Android development to port some iPhone applications we did for a client over to the Android platform. As such, I'm wondering what the best reference book I can buy is to get up to speed quickly with the features (and peculiarities) of Java. There are numerous "Learn Ruby for Java programmers" out there, but not really any reference books for going the otherway of Ruby-to-Java. I'm looking for something preferably like the "Learn Perl the Hard Way" book. I know how to code, I just need a reference on learning the proper mechanics of Java after having done Ruby (and a bit of Obj-C) work exclusively for the past few years.
