• Need example of how to create/manipulate image pixel data with iPhone SDK

  - by whiskeyspider

  Looking for a simple example or link to a tutorial. Say I have a bunch of values stored in an array. I would like to create an image and update the image data from my array. Assume the array values are intensity data and will be updating a grayscale image. Assume the array values are between 0 and 255 -- or that I will convert it to that range. This is not for purposes of animation. Rather the image would be updated based on user interaction. This is something I know how to do well in Java, but am very new to iPhone programming. I've googled some information about CGImage and UIImage -- but am confused as to where to start. Any help would be appreciated.

• Paypal Payflow pro library

  - by John Stewart

  I already have an express checkout integrated with my Codeigniter application. Now I want to integrate seamless paypal where I collect the CC information and pass it to Paypal (via backend) and once everything is approved, my application shows that to the user. All this with out ever going to Paypal's website. I know that Paypal gives a bunch of sample code but they have so many different products that advertise to do the same thing. Is there any wrapper library in PHP that I can use for handling all this? What sort of design decision is involved in migrating to such system? Would I need SSL certificates for this?

• Version control of Mathematica notebooks

  - by Etaoin

  Mathematica notebooks are, of course, plaintext files -- it seems reasonable to expect that they should play nice with a version-control system (git in my case, although I doubt the specific system matters). But the fact is that any .nb file is full of cache information, timestamps, and other assorted metadata. Scads of it. Which means that limited version control is possible -- commits and rollbacks work fine. Merging, though, is a disaster. Mathematica won't open a file with merge markers in it, and a text editor is no way to go through a .nb file. Has anyone had any luck putting a notebook under version control? How?

• How to diff two regions of the same file in Eclipse

  - by Thomas Nilsson

  I'm a TDDer and often have a need to refactor out common or similar code. If it is exactly the same there is no big problem, Eclipse can almost always do that by itself. But to get there I'm finding myself often looking at similar, but not identical, code fragments in the same, or even different, files. It would be very handy if there was a possibility to mark two regions and get Eclipse (or some other tool) to mark the differences. With this information it would be much simpler to iteratively move the regions closer until they are the same and then activate the Extract Method refactoring. It can be done in Emacs of course, but I'd like to have this readily available from Eclipse. Any pointers?

• Umbrella websites with Microsites & Blogs - recommendations

  - by pingu

  Hi guys, I'm in the process of scoping a solution for an events organisation. Their main website features information about them and blog entries etc, but they hold major events which require microsites (domain.com/event). The microsites all have a different look-and-feel, different nav structure, and custom content-managed components. The one thing that's common across everything is the blog - it will have a category for each event under which users can post. How would you guys implement this? The solution needs to be PHP, and my initial thought was CodeIgniter but if possible I'd like to avoid building the blog functionality - so I guess I could integrate it with EE or Wordpress. If anyone has any other suggestions they would be most appreciated.

• Measuring CPU time per-thread on Windows

  - by Eli Courtwright

  I'm developing a long-running multi-threaded Python application for Windows, and I want the process to know the CPU time that each of its threads has taken. I can get the overall times for the entire process with os.times() but I need to know the per-thread times. I know that there are external tools such as the Sysinternals Process Explorer, but my program itself needs to have this information. If I were on Linux, I look in the /proc filesystem, as described here. If I were writing C code, I'd use the GetThreadTimes call, as described here. So how can I accomplish this on Windows using Python?

• Caching for a Custom Repositiory Adapter for WebSphere Portal Virtual Member Manager

  - by Spike Williams

  I'm looking at writing a custom repository adapter to interact with Virtual Member Manager on WebSphere Portal 6.1. Basically, its a layer that takes a request in the form of a commonj.sco.DataObject and passes that on to an external web service, to get various information on our logged in users that is not otherwise available in LDAP. I'm concerned about the performance hit of going to a service every time we want to pull some permission from the back end. My question is, can the Virtual Member Manager handle caching of data going in and out of the custom repository adapters, or is that something I'm going to have to build into the adapter myself?

• Tag-like autocompletion and caret/cursor movement in contenteditable elements.

  - by jimeh

  I'm working on a jQuery plugin that will allow you to do @username style tags, like Facebook does in their status update input box. My problem is, that even after hours of researching and experimenting, it seems REALLY hard to simply move the caret. I've managed to inject the <a> tag with someone's name, but placing the caret after it seems like rocket science, specially if it's supposed work in all browsers. And I haven't even looked into replacing the typed @username text with the tag yet, rather than just injecting it as I'm doing right now... lol There's a ton of questions about working with contenteditable here on Stack Overflow, and I think I've read all of them, but they don't really cover properly what I need. So any more information anyone can provide would be great :)

• Printable Version of Google Visualizations DataTable

  - by maleki

  I have a custom routing application that takes information for a route from google maps. It then creates a Google Visualizations DataTable to hold all the steps in the route. My current problem is that in order to reduce overflow for very large routes, I have enabled paging in the options of the DataTable. This leads to a not so printer friendly version because only the portion of the data that is shown in the table will be printed. The other portions of the table are loaded dynamically by the API when you click prev and next. Is there a not so hard way to get the DataTable to be printer friendly when it comes time without sacrificing the ability to have paging enabled?

• Linker Error: iPhone Unit Test Bundle referencing App classes

  - by ohhorob

  Starting with an app already in development, I have carried out the instructions in the iPhone Development Guide – Unit Testing Applications I can successfully include and use my App's classes in Application-style tests that run on the device, and output their results to the console. If I add the following line of code: STAssertTrue([viewController isKindOfClass:[LoginViewController class]], @"Top view controller is not LoginViewController"); The following build error is generated: Undefined symbols: "_OBJC_CLASS_$_LoginViewController", referenced from: __objc_classrefs__DATA@0 in LoginViewTest.o ld: symbol(s) not found collect2: ld returned 1 exit status I can provide more configuration information for the project and the Testing target, but the setup works file without the [LoginViewController class] line in the test source. Without that line, I can reference the class, use it's properties and send it messages successfully. Is there a linking build setting, or bundle loading option that is required when attempting to use an App class in this fashion? Or should I find another type of test to confirm that the class of an object is the expected one?

• How to Generate Edifact message from a xml ?

  - by Clem

  Hello, I'm currently dealing with customs messages Beans in Java. After filling in the Beans with different values, I want to produce an EDIFACT CUSDEC message corresponding to each message. For each attribute of a message Bean, I have the information to put the attribute in the right place in EDIFACT CUSEDC format. Thus, I am looking for a free tool (a Java API) which could ideally convert my full-filled Bean into an EDIFACT CUSDEC message. I found a commercial solution (not free) there : http://www.datadirect.com/products/edifact-grid/index.ssp And a quick tutorial here : http://biemond.blogspot.com/2008/09/generate-edifact-message-from-xml.html But ... unfortunately it is not free.. Thanks in advance for your help!

• JDBC ResultSet.getString Before/After Start/End of ResultSet Exception

  - by Geowil

  I have done a lot of searching about this topic through Google but I have yet to find someone using getString() in the way that I am using it so I have not been able to fix this issue in the normal ways that are suggested. What I am trying to do is to obtain all of the information from the database and then use it to populate a table model within the program. I do so by obtaining the data with getString and place it into a String[] object: try { while (rSet.next()) { String row[] = {rSet.getString("DonorName"),rSet.getString("DonorCharity"),((String)rSet.getString("DonationAmount"))}; model.addRow(row); } } However I am always getting a dialog error message stating those error messages in the title: Exception: Before start of result set Exception: After end of result set The data is still added and everything works correctly but it is just annoying to have to dismiss those message windows. Does anyone have some suggestions?

• Flex 3 / ColdFusion Session Issue?

  - by dcolumbus

  Alright so this is an odd one... I have an application built in ColdFusion with a lot of the interactivity done with Flex. When a user logs in, there are session variables, as well as the client session that is evoked. When you browse to any given Flex Application, the variables are read in a used accordingly... however, on Windows (it seems XP and maybe others) for some reason session information like USER are randomly undefined... Could this be an issue with the session timing out? Even if I force a logout and log back in, it doesn't really seem to fix the issue... mind you, I cannot duplicate the bug myself, but it constantly happens on PCs.

• Is there a high-level gestures library for iPhone development?

  - by n8gray

  The iPhone platform has a number of common gesture idioms. For example, there are taps, pinches, and swipes, each with varying number of fingers. But when you're developing an app, it's up to you to implement these things based on low-level information about the number and locations of touches. It seems like this is a prime candidate for a library. You would register a delegate, set some parameters like multi-tap interval and swipe threshold, and get calls like swipeStarted/Ended, pinchStarted/Ended, multiTap, etc. Does such a library exist?

• Why are all response bodies after the first blank in Cucumber?

  - by James A. Rosen

  I'm using Cucumber (0.6.3), Cucumber-Rails (0.3.0), Webrat (0.7.0), and Rails (2.3.5) for some tests. The following scenario passes just fine: Scenario: load one page Given I am on the home page Then I should see "Welcome" The following, however, fails: Scenario: load two pages Given I am on the FAQ pag When I go to the home page Then I should see "Welcome" The problem is that the second @response.body is blank. I added a Rack middleware to get a little more information: class LogEachRequest def initialize(app); @app = app; @count = 0; end def call(env) puts "Processing request # #{@count += 1)" @app.call(env) end end It shows me only one request processed. That is, it only ever prints out Processing request # 1

• Programming languages: out of the box legibility and extensibility

  - by sova

  Two excellent results of SOLID development ideology are - Legibility - Extensibility over the life of a project (http://en.m.wikipedia.org/wiki/Solid_(object-oriented_design) Although SOLID is a set of language-agnostic design ideas, some languages inherently support these ideas better than others. Out-of-the-box or after various customizations, in your opinion which language is best-suited to be both easily readable and easy to extend functionality in? Some definitions to pre-empt biases and flamewars: Legibility: amount of thinking done to understand the code proportional to the amount of code: (amount_think-energy / amount_code) is fairly constant and as low as possible in the optimal case. Extensibility: Addition of X amount of functionality requires a change in code or code additions in proportion to X (amount_added_functionality / amount_added_code) is fairly constant and as high as possible in the optimal case. Supporting information and tutorials encouraged. Code snippets welcome.

• Writing email sniffer

  - by Rampage

  Hello, I am interested in writing an email sniffer that saves all emails sent via web based clients to hd, but I can't work out how to do this. How can I catch HTTPS mail before it is encrypted? I would really appriciate some useful info. I cannot find anything information on the web. There's a program called HTTP Analyzer V5 that does the exact thing I want to make. How should I start? If I make a packet sniffer, it's useless because all data is encrypted. Is there any other option?

• Is block style really this important?

  - by Jack Roscoe

  I just watched a video of Douglas Crockford's presentation about his 2009 book JavaScript: The Good Parts. In the video, he explains that the following block is dangerous because it produces silent errors: return { ok: false }; And that it should actually be written like this (emphasising that although seemingly identical the behavioural difference is crucial): return { ok: false }; You can see his comments around 32 minutes into the video here: http://www.youtube.com/watch?v=hQVTIJBZook&feature=player_embedded#!&start=1920 I have not heard this before, and was wondering if this rule still applies or if this requirement in syntax has been overcome by JavaScript developments since this statement was made. I found this very interesting as I have NOT been writing my code this way, and wanted to check that this information was not out of date.

• Drupal: I cannot connect to the database.. please help

  - by Patrick

  hi, I've hard time to make Drupal work on IIS Microsoft server. I've succesfully run Joomla on the same server so I'm pretty sure the following information are correct: host: localhost user: user pass: pass databaseName = servername_databasename I've set the following line in settings.php file: $db_url = 'mysql://user:password@localhost/servername_databasename'; but what I get is this: If you are the maintainer of this site, please check your database settings in the settings.php file and ensure that your hosting provider's database server is running. For more help, see the handbook, or contact your hosting provider. I don't get any other error message such as: database doesn't exist, user/pass wrong.. just this. The database is running, I can access with phpmyadmin. I've tried both "mysql" and "mysqli". The host is a private server (IIS Microsoft), the database is Mysql The database and website files upload have also been succesfull.. so I dunno what to do to fix this issue. thanks

• Which collation should I use to store these country names in MySQL?

  - by morpheous

  I am trying to store a list of countries in a mySQL database. I am having problems storing (non English) names like these: São Tomé and Príncipe República de El Salvador They are stored with strange characters in the db, (and therefore output strangely in my HTML pages). I have tried using different combinations of collations for the database and the MySQL connection collation: The "obvious" setting was to use utf8_unicode_ci for both the databse and the connection information. To my utter surprise, that did not solve the problem. Does anyone know how to resolve this issue?

• SSIS XML Decryption Message

  My SSIS package says it is successful, but when it runs it ends not doing anything (that I can see). The only thing wrong is this message (that it does not qualify as an error). Description: Failed to decrypt an encrypted XML node because the password was not specified or not correct. Package load will attempt to continue without the encrypted information I do have a password on my packages, but I don't see anywhere to put the password in when I load the Package into SSIS. Am I missing a step?
