• speech bubbles like in comics for iphone

  - by plspl

  I am new to iphone application development. I am building an iphone app where the user needs to be able to add speech bubbles (think comics) over existing images. I have some questions on how to implement this, Have an empty speech bubble image and overlay it over existing image - Do I use a separate UIImage for the speech bubble? Or should I draw the speech bubble myself? Allow the user to move the speech bubble using touch- Any pointers or examples would be great! Also let him resize the speech depending on the amount of text - Any pointers or examples would be great! Finally he should be able to add text to speech bubble - Is there a way to add textbox over an existing image? Thanks,

• PHP's apache_setenv function causes 500 Internal Server Error

  - by guitar-

  apache_setenv ( 'no-gzip', 1 ) I'm trying to disable gzip for a certain page's output, but only that page. This works fine on testing servers, but not the production server, which is running the same thing (CentOS and Apache), works on Ubuntu though. Anyway, do you know why? Or is there some other alternative? I was thinking of using ob_start () to put all output in a buffer, and then unzip it myself with a PHP function then call ob_end_flush ()... or would it not be gzipped until right before Apache sends it to the client? Thanks for any help.

• Python Framework for small website

  - by mvid

  I am planning a small, simple website to showcase myself as an engineer. My preferred language is Python and I hope to use it to create my website. My pages will be mostly static, with some database stored posts/links. The site will be simple, but I would like to have freedom in how it operates. I plan on using CSS/JS for the design, so I really just need an easy way to throw a small amount of content around. Some frameworks I have come across: Flask cherry.py Pinax Are there any suggestions? Does anyone have any experience with Python on small/hobby websites?

• UI Design Help / Advice

  - by Greg Andora

  Hey everyone, I have a dillema where our client relations department has been brought in for advice on UI and I vehemently disagree with it...even though I don't consider myself a designer at all. While I have been vocal about my disagreement about it, I've been asked to point to design standards to prove that what I'm saying is correct and that the guys in Client Relations are flat out wrong. A mockup is below, I'm trying to argue that the icons of the airplane, boat, and couch (ya, I didn't choose those either) belong in the header of the page (same area as the logo) and not in the content area of the page. Can anybody please help me by pointing me to something that helps prove my point? Thanks a lot, Greg Andora

• Custom draw button using uxtheme.dll

  - by Javier De Pedro

  I have implemented my custom button inheriting from CButton and drawing it by using uxtheme.dll (DrawThemeBackground with BP_PUSHBUTTON). Everything works fine but I have two statuses (Normal and Pressed) which Hot status is the same. It means when the user places the cursor over the button it is drawn alike regardless the button status (Pressed or not). This is a bit confusing to the user and I would like to change the way the button is drawn in Pressed & Hot status. Does anybody know a way? I have also thought about custumizing the whole drawing but the buttons use gradients, borders, shadows, etc. So it is not easy to achive the same look&feel drawing everything by myself. Is there a way to find the source code of the dll or know how to do it? Thanks in advance. Javier

• Customized sorting on DataTable in C#?

  - by Steve

  This is a C# Winform question. I have a DataGridView which is bounded to a DataTable. I construct the DataTable myself, which several DataColumn instances. When the DataTable is bound to the DataGridView, by default, every column is sortable by clicking the headers of the DataGridView. But the sorting behavior is something "by default". It seems that it is sorted by string. This is true even if I put this as my code: DataColumn dc = new DataColumn("MyObjectColumn", typeof(MyObject)); And MyObject has overriden ToString() and has implemented the IComparable interface. That means even if I have told the DataTable how to sort the special column with the implementation of IComparable interface, DataGridView still doesn't do it the way I expect. So how can I let DataTable sort data in the way I want? Thanks for the answers.

• How to add class to openframeworks project in VS2012

  - by Mr Bell

  I am normally a C# guy but trying to get into c++. I made myself a new openframeworks project by copying and pasting one of the example projects and then renaming everything to my project name. (If there is an easier way, I would love to hear it) This project has the .cpp and .h files in a sub folder called "src" which are in turn organized into virtual folders (filters???) in visual studio. How can I add a class to this project from within visual studio? If I right click on the src filter in the solution explorer and hit add class. It creates the class files at the root of the project not in the src folder. I mean it does this both in the solution explorer and where it physically places the files. This is a problem because I can't include my class files in the rest of my app, presumably because they aren't in the same folder What is the proper way to add a class file?

• Silverlight and Active Directory

  - by Refracted Paladin

  I am planning to familiarize(read teach) myself with Silverlight by building an in-house app for managing our employees. I, obviously, would need this to interact with Active Directory on some level. What are my options? Has anyone tried this before? I am currently going to explore using Services(WCF???) to do the AD interaction portion? Thoughts? There is also this SO Post on using PowerShell to interact with AD. Maybe that is a possibility? Thanks,

• Core Location question....

  - by Moshe

  This tutorial on mobileorchard.com uses 2 classes (or 2 sets of .h and .m) to implement core location. Can I just use everything there in my existing class? How would I do that? Also, is the - (id) init { self = [super init]; if (self != nil) { self.locationManager = [[[CLLocationManager alloc] init] autorelease]; self.locationManager.delegate = self; // send loc updates to myself } return self; } method the same as the usual initWithNib? I;m trying to quickly implement something based on location information. As much help describing the above linked tutorial would be helpful. Thanks. No - really, Thank You.

• No Flash, How do i handle jcupload ?

  - by acidzombie24

  I am using http://www.jcupload.com/ (basic) to upload files. I am considering having a friend write a more custom version or to do magic with ajax; so the solution should be able to work without that. With jcupload i include css, a script and write <div id="jcupload_content"></div> in my html and i am done. Problem is, with no flash i get an object box. Instead i would like is an iframe or a html form to upload the file. How do i do this? Should i detect flash from javascript and overload the div myself if no flash is available? How do i detect if flash is available? with jquery i know i can write something like $('#jcupload_content').innerHtml = blah; How do i handle the flash part?

• SKProductsRequest delegate methods are never called.

  - by coneybeare

  This used to work for me but is now not working anymore and I can't figure out why. I have in-app purchase setup in my app. I confirmed that I have a correct set of product identifiers, matched by corresponding in-app purchase items in itunesconnect. The call goes out to Apple view [productRequest start], but I never get a response back, despite setting the delegate to myself. What am I missing? NSLog(@"productIdentifiersSet: %@", productIdentifiersSet); if ([productIdentifiersSet count]) { SKProductsRequest *productRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:productIdentifiersSet]; [productRequest setDelegate:self]; [productRequest start]; } ……… - (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response { <never called> } - (void)requestDidFinish:(SKRequest *)request { <never called> } - (void)request:(SKRequest *)request didFailWithError:(NSError *)error { <never called> }

• Game Programming - GUIs

  - by Spencer

  I've been coding for a while now and would like to start looking into programming games. I know the industry's standard language is C++, for 3D graphics the main choice is between Direct 3D and OpenGL, but what is the most widely used GUI framework? I'm currently on a Mac so if native Windows API is the answer, then what is the cross platform choice? To be clear, I'm not looking for people's favourites but simply what the common or standard game industry's choice is so that I can learn and familiarize myself with it. Thanks, Spencer

• Fastest way to list all primes below N in python

  - by jbochi

  This is the best algorithm I could come up with after struggling with a couple of Project Euler's questions. def get_primes(n): numbers = set(range(n, 1, -1)) primes = [] while numbers: p = numbers.pop() primes.append(p) numbers.difference_update(set(range(p*2, n+1, p))) return primes >>> timeit.Timer(stmt='get_primes.get_primes(1000000)', setup='import get_primes').timeit(1) 1.1499958793645562 Can it be made even faster? EDIT: This code has a flaw: Since numbers is an unordered set, there is no guarantee that numbers.pop() will remove the lowest number from the set. Nevertheless, it works (at least for me) for some input numbers: >>> sum(get_primes(2000000)) 142913828922L #That's the correct sum of all numbers below 2 million >>> 529 in get_primes(1000) False >>> 529 in get_primes(530) True EDIT: The rank so far (pure python, no external sources, all primes below 1 million): Sundaram's Sieve implementation by myself: 327ms Daniel's Sieve: 435ms Alex's recipe from Cookbok: 710ms EDIT: ~unutbu is leading the race.

• Script or utility to export from ScrewTurn Wiki into Confluence?

  - by jrummell

  Has anyone tried migrating from ScrewTurn to Confluence? I'm hoping that I can export the ScrewTurn database to xml and then use a utility to put it in a format that Confluence can understand - perhaps the format used by the Universal Wiki Converter. Has anyone used such a utility? Is there anything I should know before I try to write one myself? Update: I've installed the Confluence trial and I took a look at the backup. There's an entities.xml file that looks like the data store. The root tag is <hibernate-generic>, which leads me to believe that they use Hibernate. I'm not familiar with Hibernate, but this should be useful.

• Getting keyboard size from user info in Swift

  - by user3746428

  I have been trying to add some code to move my view up when the keyboard appears, however I am having issues trying to translate the Objective C examples into Swift. I have made some progress but I am stuck on one particular line. These are the two tutorials/questions I have been following: How to move content of UIViewController upwards as Keypad appears using Swift http://www.ioscreator.com/tutorials/move-view-when-keyboard-appears Here is the code I currently have: override func viewWillAppear(animated: Bool) { NSNotificationCenter.defaultCenter().addObserver(self, selector: "keyboardWillShow:", name: UIKeyboardWillShowNotification, object: nil) NSNotificationCenter.defaultCenter().addObserver(self, selector: "keyboardWillHide:", name: UIKeyboardWillHideNotification, object: nil) } override func viewWillDisappear(animated: Bool) { NSNotificationCenter.defaultCenter().removeObserver(self) } func keyboardWillShow(notification: NSNotification) { var keyboardSize = notification.userInfo(valueForKey(UIKeyboardFrameBeginUserInfoKey)) UIEdgeInsets(top: 0, left: 0, bottom: keyboardSize.height, right: 0) let frame = self.budgetEntryView.frame frame.origin.y = frame.origin.y - keyboardSize self.budgetEntryView.frame = frame } func keyboardWillHide(notification: NSNotification) { // } At the moment I am getting an error on this line: var keyboardSize = notification.userInfo(valueForKey(UIKeyboardFrameBeginUserInfoKey)) If someone could let me know what this line of code should be, I should manage to figure out the rest myself.

• Is there any way to use getaddrinfo() and freeaddrinfo() and still be the program compatible with le

  - by Sam C.

  Hi, in the Winsock2 library getaddrinfo() and freeaddrinfo() was only added in Windows XP and on. I know how to replace them in legacy systems, but a conditional use depending on the Windows version won't help. The application won't start in 9x with a message saying that it was linked to a missing export in WS2_32.dll. I'm using MinGW to compile and link the code and would like to keep using it. Maybe writing those functions by myself? Thank you very much for everything.

• string replace in file using C

  - by Hristo

  I haven't yet implemented this, I'm still in the thinking stage, but I have to go through a file and replace a certain string with another string. For example, <img src="/images/logo.gif" ... should become <img src="/proxy/www.example.com/images/logo.gif" ... Any advice on how I can approach this? Perhaps there exist some "string replace" C functions that would do this for me that I don't know about...? Right now, if I had to write this function myself, I would give it as parameters the file, string to replace, replacement string. Then I would manually go through the file and look for an occurrence of the string and recreate it. This, however, seems very inefficient. Are there better ways to do this? Thanks, Hristo

• My first .net web app - should I go straight to MVC framework (c.f. ASP.net)

  - by Greg

  Hi, I'm done some WinForms work in C# but now moving to have to develop a web application front end in .NET (C#). I have experience developing web apps in Ruby on Rails (& a little with Java with JSP pages & struts mvc). Should I jump straight to MVC framework? (as opposed to going ASP.net) That is from the point of view of future direction for Microsoft & as well ease in ramping up from myself. Or if you like, given my experience to date, what would the pros/cons for me re MVC versus ASP.net? thanks

• How would you fool your boss, if you needed to? [closed]

  - by Starx

  Even as a programmer myself, I am not always in mood of coding, so I think of a way to fool my boss and GET GOING..... (if you know what I mean). Like one time I wanted to go home early, I said to my boss, "Sir, I have a check up, I need to meet my doctor at 12:00 pm today". And I was out of there Well, I am doing this, so I thought others might also have done something like this or wanted to do something like this. So, How about sharing them?

• Scrolling list in Android home screen widget

  - by DanyW

  Hi folks, I am trying to teach myself the basics of Android dev. At the moment I am experimenting with home screen widgets. I would like to create a simple widget that lists all my bookmarks. Somewhere in my googling I read that ListView is not usable in a widget. What's the best way to display a scrolling list in a widget? An example would be fantastic, but otherwise point me in the right general direction and I can research further. Thanks in advance, Dany.

• Delphi 7: how to execute shell command and check the result?

  - by mawg

  I'm using Delphi 7 and can't predict the target version of Windows. I need to create a database (probably MySql, but might be something else) and define some table structures. I do not need to populate any data. Unfortunately, all of the ADO components seem to expect that a database already exists and they will then allow you to manipulate it. So, since it's only a few simple commands, I thought that I might as well use ShellExectute(). Agree? Disagree? Can anyone give me a sample code which will attempt to run "MySql --version" and let me check the result? After that I should be able to figure it out for myself. Thanks.

• Recommended Model Based Testing Tools

  - by ModelTester

  Does anyone have any suggestions on what Model Based Testing Tools to use? Is Spec Explorer/SPEC# worth it's weight in tester training? What I have traditionally done is create a Visio Model where I call out the states and associated variables, outputs and expected results from each state. Then in a completely disconnected way, I data drive my test scripts with those variables based on that model. But, they are not connected. I want a way to create a model, associate the variables in a business friendly way, that will then build the data parameters for the scripts. I can't be the first person to need this. Is there a tool out there that will do basically that? Short of developing it myself.

• Difference between an LL and Recursive Descent parser?

  - by Noldorin

  I've recently being trying to teach myself how parsers (for languages/context-free grammars) work, and most of it seems to be making sense, except for one thing. I'm focusing my attention in particular on LL(k) grammars, for which the two main algorithms seem to be the LL parser (using stack/parse table) and the Recursive Descent parser (simply using recursion). As far as I can see, the recursive descent algorithm works on all LL(k) grammars and possibly more, whereas an LL parser works on all LL(k) grammars. A recursive descent parser is clearly much simpler than an LL parser to implement, however (just as an LL one is simply than an LR one). So my question is, what are the advantages/problems one might encounter when using either of the algorithms? Why might one ever pick LL over recursive descent, given that it works on the same set of grammars and is trickier to implement? Hopefully this question makes some amount of sense. Sorry if it doesn't - I blame my the fact that this entire subject is almost entirely new to me.

• Stuck at "Hello World" with IntelliJ IDEA 9.0.1 for Scala

  - by Alex R

  I've been using Eclipse since 2.x and and IDEs in general for over 20 years (since Turbo Pascal and Turbo C in the late '80s!). (that preamble is supposed to imply, "I'm not an idiot" ... LOL :-] ) I'm trying to use the debugger in IntelliJ 9.0.1. I've resigned myself to an old standby: class hello { def main(a: Array[String]) = println("got args: " + a) } Alas, I'm unable to get even this simple Scala example to run. I'd like to eventually put a breakpoint in it, but for now just running it would be great. I have Java 1.6u20 and the Scala plug-in 0.3.473 (January 2010). The error below summarizes my experience: What possibly could I be doing wrong? Thanks

• How to prepare for a Java test?

  - by Zenzen

  Ok so in two days I have a test for my dream job (well it's an internship, but still!) and for quite some time now I've been reading the SCJP Guide book in order to prepare myself. BUT seeing how slow my reading speed is I guess finding a website with some "java essentials" or "standard java test questions" and going through it in those 2 days would be a better idea. Don't misunderstand me, I do have java experience and it's "only" an internship, but we all know how programming tests look like and how tricky they can be. So are there any online resources you could recommend me? I know 2 days is not much, but well I was informed bout the test 1-2days ago.
