• Flash AS3 for loop query

  - by jimbo

  I was hoping for a way that I could save on code by creating a loop for a few lines of code. Let me explain a little, with-out loop: icon1.button.iconLoad.load(new URLRequest("icons/icon1.jpg")); icon2.button.iconLoad.load(new URLRequest("icons/icon2.jpg")); icon3.button.iconLoad.load(new URLRequest("icons/icon3.jpg")); icon4.button.iconLoad.load(new URLRequest("icons/icon4.jpg")); etc... But with a loop could I have something like: for (var i:uint = 0; i < 4; i++) { icon+i+.button.iconLoad.load(new URLRequest("icons/icon"+i+"jpg")); } Any ideas welcome...

• Java reduce CPU usage

  - by steve

  Greets- We gots a few nutters in work who enjoy using while(true) { //Code } in their code. As you can imagine this maxes out the CPU. Does anyone know ways to reduce the CPU utilization so that other people can use the server as well. The code itself is just constantly polling the internet for updates on sites. Therefore I'd imagine a little sleep method would greatly reduce the the CPU usage. Also all manipulation is being done in String objects (Java) anyone know how much StringBuilders would reduce the over head by? Thanks for any pointers

• Facebook Open Graph - Grab how many times a page has been liked?

  - by DoMx

  I have a site that allows users to create a saying and then users "like" those sayings on Facebook. http://www.likeylikey.net/ I got a friend to throw up this simple code in less than 2 hours so it's basic. He knows little to nothing regarding the Open Graph API. Basically, I want to know how I can programmatically store how many times a page has been liked so I can list a "Top 10, most liked pages" list. Right now the index shows a list of all created pages and now I just wish to show the 10 most liked but I need a way of pulling that information from Facebook. Is this possible?

• Brief Explanation of C Supersets?

  - by Ben Hooper

  I'm getting more and more confused in regards to C's supersets the further I venture into the programming world. There's just so many versions.. C, C++, C#, Objective-C, Objective-C++ and God knows what else. I only know tidbits about these languages (some are object-oriented, some are procedural, C was originally developed for UNIX, C++ started as an extension and is used primarily on the Windows OS, Objective-C is primarily used on Linux and Mac OS/iOS, etc), but I'm not even sure that what I know is correct. I would just like someone to shed some light on what I "know" - a little bit more information about which are successive versions, which platforms each are generally used on, which are the best versions to learn, etc if anyone is feeling generous. :) Thanks. :)

• Remembering Form information

  - by Pete Herbert Penito

  Hi everyone! I'm sorry if this has been asked before but I feel my situation is a little different... I have a huge form (like 50 questions involving checkboxes, drop downs, text boxes and textareas) When a user submits a form and the validation page throws an error, is there an easy way to keep the info they entered? My intitial form is on form.php and then the form action is form_posted.php, before anything is run on form_posted.php I have my validation code which sends the user back to form.php with an error number (eg. form.php?error=3) if there was a problem with any in particular. This is done with header("form.php?error=3") so on form.php do the posted variables exist? even tho the page wasn't specifically sent with any posted variables. Also if this is the case, is it completely secure to be making the value of a textbox what it was before? like <input type="text" value="php echo $_POSTED["username"] ?>">

• How do I assign a value from params, or session, whichever exists?

  - by irkenInvader

  What is the "Rails-way" or the "Ruby-way" of doing the following: In my controller, I'm creating and instance of an Options class. It will be initialized with information in the params hash if the params hash exists. Otherwise, it will check the sessions hash for the information. Finally, it will initialize with defaults if neither params nor session has the data it needs. Here is how I'm doing it now (it works fine, but it seems a little ugly): if params[:cust_options] @options = CustomOptions.new( params[:cust_options] ) else if session[:cust_options @options = CustomOptions.new( session[:cust_options] ) else @options = CustomOptions.new end end session[:cust_options] = @options.to_hash Like I said, everything is working fine, I'm just looking for a more idiomatically Ruby way of writing this block of code.

• Is it legal for a C++ reference to be NULL?

  - by BCS

  A while back I ran into a bug the looked something like this: void fn(int &i) { printf(&i == NULL ? "NULL\n" : "!NULL\n"); } int main() { int i; int *ip = NULL; fn(i); // prints !NULL fn(*ip); // prints NULL return 0; } More recently, I ran into this comment about C++ references: [References arguments make] it clear, unlike with pointers, that NULL is not a possible value. But, as show above, NULL is a possible value. So where is the error? In the language spec? (Unlikely.) Is the compiler in error for allowing that? Is that coding guide in error (or a little ambiguous)? Or am I just wandering into the minefield known as undefined behavior?

• Managed HttpListener vs C++ Network Lib - Requires admin rights?

  - by Max

  So, I have noticed that starting an HttpListener is considered impolite according to Win 7. I cannot do so without administrative rights without adding myself to some URL reservation list. In theory, this is alright, but I'd like to make my program as little invasive as possible. My main other alternative is something like the c++ Network Library, which utilizes boost. This is probably not as simple as a HttpListener though. Will this circumvent the admin rights requirement for listening to some HTTP url? How does windows handle http listening? Right now I'm just listening to http://+:xxxx/url, I guess it's fully possible to just create a Socket listening at port xxxx and provide my own/third party http implementation?

• Changing gmail Settings with Ruby

  - by Technocrat

  I need to configure my gmail account(s) programmatically with Ruby. I checked out the apps api and it looks like the simplest possible solution would be to use ClientLogin for logging in and a simple XML PUT for changing the forwarding setting, for example. I wrote a little test script like so: http://gist.github.com/373457 It would appear that the call to ClientLogin works because it comes back with an Auth= token. When it sends the PUT request to google, however, it comes back with a RestClient::Unauthorized exception. I rewrote the script with pure net/https and it turns out the message I'm getting is invalid token, yet I can't figure out what is wrong with my token. Can anyone else see it?

• Are there any medium-sized web applications built with CGI::Application that are open-sourced?

  - by mithaldu

  I learn best by taking apart something that already does something and figuring out why decisions were made in which manner. Recently I've started working with Perl's CGI::Application framework, but found i don't really get along well with the documentation (too little information on how to best structure an application with it). There are some examples of small applications on the cgi-app website, but they're mostly structured such that they demonstrate a small feature, but contain mostly of code that one would never actually use in production. Other examples are massively huge and would require way too much time to dig through. And most of them are just stuff that runs on cgiapp, but isn't open source. As such I am looking for something that has most base functionality like user logins, db access, some processing, etc.; is actually used for something but not so big that it would take hours to even set them up. Does something like that exist or am i out of luck?

• User Drawn Controls: the MSN chat window

  - by Tommy

  I'm wondering about the famous MSN chat clients conversation windows! I'm sure there must be alot of different aspects but I'd like to focus on those little sliding panes. For instance where the pictures of the people in the conversation is displayed. When you click the collapse button the pictures dissapear and the panel gracefully slides in, and when you click it again to expand, it slides out and the pictures are smoothly faded in. How would one go about customly drawing a control in WinForms that had simmilar behaviour?

• Samsung UMPC, Built in Camera doesn't support DirectX how can I use it?

  - by Markive

  The Samsung Q1 Ultra, is the perfect device for my software except that the built in camera seems to be incompatible with standard DirectX drivers, so my .Net camera implementation can't use the device. I have limited experience in this area.. Even Skype can't access this camera, but a little program from Samsung can.. I've looked at the program's assemblies and it's too obfuscated to see inside so I can't see anyway to use them.. What sort of camera could this be? Are there any .Net classes / implementations I can use to access this camera?

• How can I avoid causing memory leaks in Firefox?

  - by mrdanimal

  It seems that there is a lot of information on memory leaks in IE and how web developers can avoid them, but I can't find much on avoiding leaks in FF. I've found lots of random tips on how end users can tweak their preferences, or tips for extension developers, but little on what I can do as a web developer to make sure my pages don't leak. Am I missing something? It seems lazy to just blame it on the user and say "you've got too many extensions". Or are the major patterns the same as in IE -- circular references and all that? Also, if anyone knows of any tools to troubleshoot leaks in FF, that would be great. I found this: https://addons.mozilla.org/en-US/firefox/addon/2490/ But it's apparently just for chrome and extension development.

• Iframe not displaying content

  - by a coder

  This snippet was gathered from a random youtube video: <iframe class="youtube-player" src="http://www.youtube.com/embed/http://www.youtube.com/v/gnrvYsZWR1c?rel=0" title="YouTube video player" type="text/html" frameborder="0" height="390" width="480"></iframe> Again, a little easier to read: <iframe class="youtube-player" src="http://www.youtube.com/embed/http://www.youtube.com/v/gnrvYsZWR1c?rel=0" title="YouTube video player" type="text/html" frameborder="0" height="390" width="480" ></iframe> It is not displaying the embedded youtube in Firefox 15.0.1 on Windows or Linux. Is there a problem with how this snippet is constructed, or is Firefox simply not displaying iframe content?

• Split text files Accross threads

  - by Kevin

  The problem: I have a few text files (10) with numbers in them on every line. I need to have them split across some threads I create using the pthread library. these threads that are created (worker threads) are to find the largest prime number that gets sent to them (and over all the largest prime from all of the text files). My current thoughts on solutions: I am thinking myself to have two arrays and all of the text files in one array and the other array will contain a binary file that I can read say 1000 lines and send the pointer to the index of that binary file in a struct that contains the id, file pointer, and file position and let it crank through that. a little bit of what I am talking about pthread_create(&threads[index],NULL,calc_sqrt,(void *)threadFields[index]);//Pass struct to each worker Struct: typedef struct threadFields{ int *id, *position; FILE *Fin; }tField; If anyone has any insight or a better solution it would be greatly appreciated Thanks

• What SQL ORM may i use to replace this old code

  - by acidzombie24

  Sorry since this question is specific to my problem. While learning reflections i did a mini SQL ORM in a week then minor tweaks while using it for another week. Since it has very little work put into it, its really only compatibility with sqlite. I havent had problems with the code so far but i would like to port it to something that supports TSQL or MySql. The example code is here which is outdated but has the most used functions in my class. What library can i port that code over too with the smallest about of pain. Note that it must support foreign keys.

• How to "flick" a UIImageView?

  - by Meltemi

  I've got some UIViews that I'd like the user to be able to "flick" across the screen. They're not scroll views. They simply contain a raster image (png). Can anyone point me to some sample code, etc to help get me started? Something a little more heavyweight than "MoveMe" out there that helps detect a "flick" (vs a "nudge" or a drag and drop) and then carries the view off in the direction of the "flick"? OpenGL probably overkill. If possible I'd like to stay w/in the realm of Core Graphics/Animation.

• How should I structure my iPhone OpenGL ES 1.1 game?

  - by Ryan

  I am building an iPhone OpenGL ES 1.1 game. I am using the OpenGL ES template provided by xcode. I am only using the ES1Renderer. I've coded some basic touch actions the user can take, and I've begun to think about the overall structure of the code. All I'm really doing is using C in the ES1Renderer.m for my entire game state. I have an array of bullet structs, an array on enemy structs, etc.. Besides using this structure, where my entire game state is in ES1Renderer.m as C arrays and structs, what other ways are there to structure the code? Should I be using C++ or Objective-C classes to represent the enemies so they are more modular? The main reason I ask this is because I don't normally code in C, C++ and Objective-C..so I am a little fuzzy on coming up with a good architecture here.

• Can I use the decorator pattern to wrap a method body?

  - by mgroves

  I have a bunch of methods with varying signatures. These methods interact with a fragile data connection, so we often use a helper class to perform retries/reconnects, etc. Like so: MyHelper.PerformCall( () => { doStuffWithData(parameters...) }); And this works fine, but it can make the code a little cluttery. What I would prefer to do is decorate the methods that interact with the data connection like so: [InteractsWithData] protected string doStuffWithData(parameters...) { // do stuff... } And then essentially, whenever doStuffWithData is called, the body of that method would be passed in as an Action to MyHelper.PerformCall(). How do I do this?

• Edit Mode Delete Spinner Icon for Specific TableView Rows

  - by Michael Bordelon

  I have a grouped tableview. Each section has three rows. I need to be able to delete one section at a time. Using the standard edit mode, I can make it work. However, the delete icon shows up to the left of each cell, not just the first row in each section. Is there a way to suppress the little spinner icon for all rows except the first? I am hoping there is an easy way to do this without subclassing. Thanks for your help. Here is a screenshot to help visualize it: http://picasaweb.google.com/lh/photo/ll-EJY5ACw7oqHH1xKBQ8w?feat=directlink

• Javascript string.replace with regex

  - by Jimbo

  I want to replace a url querystring parameter with a new value if it already exists or add it on if not. e.g. The current url could be: a. www.mysite.com/whatever.asp?page=5&version=1 OR b. www.mysite.com/whatever.asp?version=1 I need the resulting url to be www.mysite.com/whatever.asp?page=1&version=1 I suspect I can use string.replace with a regex to do this the most intelligent way but am hoping for a little help with it from someone more experienced with regexs :) Thanks!

• DDD Infrastructure services

  - by Zygimantas

  Hello, I am learning DDD and I am a little bit lost in Infrastructure layer: As I understand, "all good DDD applications" should have 4 layers: Presentation, Application, Domain and Infrastructure. Database should be accessed using Repositories. Repository interfaces should be in Domain layer and repository implementation - in Infrastructure (reference http://stackoverflow.com/questions/693221/ddd-where-to-keep-domain-interfaces-the-infrastructure). Application, Domain and Infrastructure layer should/may have services (reference www.lostechies.com/blogs/jimmy_bogard/archive/2008/08/21/services-in-domain-driven-design.aspx), in example EmailService in Infrastructure layer which sends Email messages. BUT, inside Infrastructure layer we have repository implementations, which are used to access database. So, in this case, repositories are database services? What is the difference between Infrastructure service and repository? Thanks in advance!

• Using svn remove - preserve file on disk instead of having it deleted?

  - by user246114

  Hi, I am creating an eclipse project, which generates a lot of files I don't want to keep under version control. For example, it creates a project folder like: project/ bin/ horse.class cow.class src/ horse.java cow.java so what I do is add the project folder to svn, like: svn add project this puts everything under control, even the bin and .class files. All of those files will have the little 'a' next to them. How can I simply remove the 'add' status from those files? If I try: svn remove bin/horse.class I have to use the --force option and it deletes the file from disk. Is there a way to simply remove it from source but not delete the file from disk? Thanks
