• Save objects to a database?

  - by Eric

  So far in my .Net coding adventures I've only had a need to save information to files. So I've used XmlSerializer and DataContractSerializer to serialize attributed classes to XML files. My next project, however, requires that I save and retrieve information from a SQL server database. I'm wondering what my options are for doing this. The current version of the app, which was not created by me, uses a lot of hard coded SQL commands. But now I'm trying to avoid doing anything where I have to read or write individual fields to or from the database or objects. I especially want to avoid a lot of hard coded SQL in my code. I like how the serializer classes just figure out how to read and write XML files based on the attributes and or public properties of the class. Is there something similar for a database rather then XML?

• best way to create tables with ORM?

  - by ajsie

  assume that i start coding an application from scratch, is the best way to create tables when using an ORM (doctrine), to manually create tables in mysql and then generate models from the tables, or is it the other way around, that is to create the models in php and then generate tables from models? and if i already have a database, will the models created be optimal? cause i have heard some say that its best to create the database from scratch when using ORM, so that the relations are optimized for OOD. share your thoughts!

• Where is the best place to start learning Java Socket Programming?

  - by MarcoBoomTing

  I wish to create a Java Socket server which can be connected to using Javascript and/or Flash. I have experience in Connecting to sockets in flash, and using a comet like system in Ajax. I wish to make a live communication system, which will intale multiple connections to the server from various clients, needing almost instant communication between peers. I coded a system like this in PHP but I want to convert it to Java, simply because I don't want the PHP engine to be tied up on this Sever, as it serves all the web stuff normally on the site, and i've heard is more powerful for this sort of thing. Just looking for advice on where I can start learning how to write this sort of system using Java? I have previous coding experience in PHP, Javascript, Adobe Air and AS3 if That helps?

• how to access a different movieclip within the flash in AS3

  - by Pieter888

  I've been trying to learn Action Script 3 the past few weeks, making tiny interactive games to learn the basics. I stumble upon a problem every now and then but most of the times google helps me out. But this problem has got me stuck so please help: The main stage contains two objects(movieclips), the player and a wall. The player has got his own code so when I drag in the player object I don't have to write any code into the main stage to be able to move the player. This all worked pretty well and I now wanted to add the wall so the player actually has something to bounce into. Now here is the problem, I want to check if the player touches the wall, I've done this before but that was when I used the main stage as my coding playground instead of putting the code in movieclips. How can I check if the player hits the wall within the movement code of the player object?

• What is your favorite colorscheme FOR PROGRAMMING in Vim?

  - by ThomasGHenry

  I think this is a relevant question for programmers and I'd like to hear other people's answers because some syntax highlighting color schemes are better on the eyes than others. This can affect productivity as much as ergonomic keyboards or anything else on here. It's about comfort and productivity. So, I'm curious. Do you find some color schemes better adapted for some languages over others? At the other end of the spectrum, I think coding without syntax highlight is awful and slow going. Does anyone work better like this? Thanks! EDIT: so we'll try it as a community wiki. Similar Question

• 'An error occurred. Please try later' message on Facebook authentication dialog

  - by Eugene Zhuang

  I am a newbie who is trying to create a Facebook app using PHP and Facebook's PHP SDK. The app is hosted on Heroku, and the sample app that they provided is working fine. However, I am now trying to get the sample app to work on Apache 2.2, and I have encountered a lot of problems along the way. Well, straight to the point, my latest problem will be trying to do Facebook login on localhost, but the 'An error occurred. Please try later' appears on the popup dialog. This does not happen on Heroku. Will someone please enlighten me on if there's any steps that I can take to overcome this error? I don't think it got to do with any coding error since I am just following the provided sample app. Thanks!

• DB fields not showing up in association custom queries?

  - by Kevin

  I have a notification list that the user can select different show options for different kinds of notifications along with how many results are returned. I'm keeping them in the user model because I want the custom sort to stay with the user between sessions. Here is the association in my user model: has_many :notifications, :class_name => "Notification", :foreign_key => "user_id", :conditions => ["won = ? and lost = ? and paid = ?", self.prefs_won, self.prefs_lost, self.prefs_paid], :limit => self.prefs_results.to_s But when I use the above code, Rails throws me an "unknown method" error for self.prefs_won. It is definitely a field in my database and set as a boolean value, but Rails can't find it... what's the problem?

• NSUserDefaults doesn't save

  - by JJSaccolo

  Hi everybody! i'm trying to save some informations in an iphone/ipad app. The problem is that it works but if i close the app (with the home button on the simulator or closing with cmd+q) the informations become lost! this is my code (and, if you see, i used "syncronize") - (IBAction)choose1{ NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; [defaults setObject:@"choose1" forKey:@"choose"]; [defaults synchronize]; } - (IBAction)choose2{ NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; [defaults setObject:@"choose2" forKey:@"choose"]; [defaults synchronize]; } - (IBAction)openview{ NSString *var = [[NSUserDefaults standardUserDefaults] objectForKey:@"choose"]; if (var == @"choose1"){ [self pushViewController:view1 animated:YES];} else if (var == @"choose1"){ [self pushViewController:view2 animated:YES]; } } I don't understand why :(

• C++ IDE for OSX

  - by gprime

  When i was at university i wrote a lot of C++. I primarily used either Visual Studio (at the time it was version 6) or VIM (if i was on linux) as an editor to write my code. Since i have graduate and have been working primarily in web programming i have stopped writing C++. Since i graduated i have also bought myself and started using my Mac exclusively. I am now starting to get back to my C++ coding (just for fun) and would like an opinion on good IDE's for Mac. I am currently using xCode which seems kinda cool because it has everything built into it. Do any of you have any other IDE's that you would suggest that i give a shot or should i just stick to xCode?

• Protocols/Interfaces in Ruby

  - by fifigyuri

  While coding in Ruby I did not really miss the type-orientedness of Java or C++ so far, but for some cases I think it is useful to have them. For Python there was a project PyProtocols which defined interfaces and protocols for objects. Does a similar initiative also exist for Ruby? I would like to be able to declare the expected parameters for some methods for some objects (for the entire code I find such think useless). It the method during the execution receives an unexpected input, it tries to adapt it or if it cannot, it throws an exception. Does something similar exist for Ruby? Introducing types for a type-less language like Ruby might sound freak, but I think types are sometimes useful. Thanks for help.

• WordPress [img] tags

  - by Lokheed

  Hey guys, I'm trying to allow that standard BB [img] [/img] tags on my WordPress blog. I got this snippet from the net, but it only works on lower case [img] tags. I'd like it to apply to both [img] and [IMG]. As you can tell, I'm totally not a coder. function embed_images($content) { $content = preg_replace('/\[img=?\]*(.*?)(\[\/img)?\]/e', '"<img src=\"$1\" alt=\"" . basename("$1") . "\" />"', $content); return $content; } add_filter('comment_text', 'embed_images'); I know '||' is 'or' but don't know enough coding to make the changes. Any help is greatly appreciated. Thanks.

• Updating a database periodically with Java

  - by MSR

  I would like to perform updates to a MySQL database using two separate classes (that do different things) -- one doing so every 10 seconds, and the second every minute. I have a few gaps in my Java knowledge and I'm wondering what the best way to achieve it is. Importantly, if connectivity to the database is lost, I need reconnection attempts to occur indefinitely, and I'm guessing the use of Prepared Statements will make queries more efficient. Should the connection to the database be left open all the time or closed between the updates being run? Maybe I also need to think about clearing objects/resources out of memory if the class instances are going to be run indefinitely.

• Why use threading data race will occur, but will not use gevent

  - by onlytiancai

  My test code is as follows, using threading, count is not 5,000,000 , so there has been data race, but using gevent, count is 5,000,000, there was no data race . Is not gevent coroutine execution will atom "count + = 1", rather than split into a one CPU instruction to execute? # -*- coding: utf-8 -*- import threading use_gevent = True use_debug = False cycles_count = 100*10000 if use_gevent: from gevent import monkey monkey.patch_thread() count = 0 class Counter(threading.Thread): def __init__(self, name): self.thread_name = name super(Counter, self).__init__(name=name) def run(self): global count for i in xrange(cycles_count): if use_debug: print '%s:%s' % (self.thread_name, count) count = count + 1 counters = [Counter('thread:%s' % i) for i in range(5)] for counter in counters: counter.start() for counter in counters: counter.join() print 'count=%s' % count

• Looking for an approach to program a mobile website for any device. Are there any?

  - by ChrisBenyamin

  My wish is to know how I can program a mobile website, that fit to all mobile phones. Are there any special approaches to recognize a device and render the code according to it? Which tools and coding languages are required? My first thought was to hold the website in XML, which would be parsed depending on the device. You have to consider old phones, even devices with only wap support. For example: The mobile website has to recognize Nokia N75 and render/send the code that looks optimal for this device. Same thing with an iPhone or a Motorola Razr.

• Drupal and Back-End Complexity

  - by Brian

  Currently I am working on a school website, and we are still in the decision-making process of choosing a framework (we know that we're not using Joomla! or hand-coding). Drupal came up as a viable choice, and currently, that is my best bet for the site. However, I have an issue with CMS's in general. I would like to develop a quite complicated and specifically custom-suited back-end application for teachers to interact with individual students, including the design of shared/custom calendars, announcement privileges, etc. I currently have a bit of expertise with HTML, CSS, PHP, MySQL, and I could wrap my head around some JavaScript and AJAX stuff if need-be. However, would such a complicated application work with Drupal (in that I could create it to specifically suite my purposes)?

• Is there a way to arbitrarily load Resources at runtime in Android?

  - by Omega

  I've got some XML resources in my Android app. Each one has a different name like "bicycle.xml" and "car.xml". I'd like to know if there's a way to load resources based on conditions during run time. As an example... Say I had a text input in my app. When the user enters "bicycle", my app can look up an XML resource by that name, parse and load it. Whereas if they enter "car", they would end up with the data from the other XML file. I've noticed so far that to load resources, you have to use the autogenerated "R" class, which restricts you to hard-coding resources at compile time.

• How do C++ header files work?

  - by PulpFiction

  Hi all. When I include some function from a header file in a C++ program, does the entire header file code get copied to the final executable or only the machine code for the specific function is generated. For example, if I call std::sort from the <algorithm> header in C++, is the machine code generated only for the sort() function or for the entire <algorithm> header file. I think that a similar question exists somewhere on Stack Overflow, but I have tried my best to find it (I glanced over it once, but lost the link). If you can point me to that, it would be wonderful.

• Java Authenticator on a per connection basis?

  - by Martijn Laarman

  I'm building an Eclipse plugin that talks to a REST interface which uses Basic Authentication. When the authentication fails I would like to popup my plugin's settings dialog and retry. Normally I could use the static Authenticator.setDefault() to setup an authenticator for all HttpURLConnection's for this, but since I am writing a plugin I don't want to overwrite Eclipse's default Authenticator (org.eclipse.ui.internal.net.auth); I thought of setting my custom Authenticator before loading and putting Eclipse's default back afterwards, but I imagine this will cause all sorts of race issues with multithreading so I quickly lost that notion. Google searches yield all sorts of results basically telling me it's not possible: The Java URLConnection API should have a setAuthenticator(Authenticator) method for making it easier to use this class in multi-threaded context where authentication is required. Source If applications contains few third party plugins and each plugin use its own Authenticator what we should do? Each invocation of "Authenticator.setDefault()" method rewrite previously defined Authenticator... Source Are there any different approaches that might help me overcome this issue?

• attaching multiple files to a domain class

  - by Emyr

  I've seen various Grails plugins which allow easier handling of file uploads, however these tend only to support a single file per form-submit. I'd like a multi-attach form where as soon as you pick one file, an extra field and button is added using JS (various sites do it like this). Do you know of any good plugins which provide elegant uploading of multiple files without excessive coding? A progress bar either per-file of for the whole process would also be very nice. I don't know to what extent I can allow GORM to handle a java.io.File field (or in this case a Collection<File>).
