• string holding text every \n

  - by gcc

  I tried to take input in form of string, specifically: int i=0; char c[50][500]; for(;i<50;++i) scanf("%s",A[i]); The input is x is a website that allows the easy[1] creation and editing of any number of interlinked web pages via a web browser using a simplified markup language or a WYSIWYG text editor. In my program, I want the text to be stored as: A[0]="x is a website that allows the easy[1] creation and editing of any number of interlinked" A[1]=" web pages via a web browser using a simplified markup language or a WYSIWYG text editor." But my code causes the text to be stored as A[0]="is" A[1]="a" A[2]="website" .... What am I doing wrong?

• how to display CFStringType? Like kABHomeLabel

  - by xiaozi

  I know that NSString and CFString are toll-bridge, they can convert in such a way. CFStringRef cfStr; NSString* anStr=(NSString*)cfStr; however,when I convert string in such a case when dealing addressbook NSString* homeLabel=(NSString*)kABWorkLabel; then homeLabel is "$!!$"; the other pre-defined CFStringRef in the addressbook property is the same. in my program,I want to get both the label and the label item's info. NSString* label=ABMultiValueCopyLabelAtIndex(multi,i); so how to correctly get the string of the label? Thanks!

• Closed Source Java Applications

  - by Paul

  I am taking programming courses and we have been discussing Open Source and having a bit of an argument over the confusion. Just because Java is Open Source, the licensing on developed applications starts at the developer, correct? Someone is arguing about the use of code from a complete program just because "Java is Open Source". If I write a Java application, what are the limitations on how I can distribute it or how someone else can use it? Assume here that I DO NOT want someone having access to my source. Thanks

• Does a persons' first programming language affect their programming style and if so, how? [closed]

  - by Scott Walsh

  I was speaking to an experienced lecturer recently who told me he could usually tell which programming language a student had learnt to program in by looking at their coding style (more specifically, when programming in other languages to the one which they were most comfortable with). He said that there have been multiple times when he's witnessed students attempted to write C# in Prolog. So I began to wonder, what specific traits do people gain from their first (or favourite) language which are carried over into their overall programming style, and more interestingly what good or bad habits do you think people would benefit from or should be wary of when learning specific language?

• Keeping track of threads when creating them recursively

  - by 66replica

  I'm currently working on some code for my Programming Languages course. I can't post the code but I'm permitted to talk about some high level concepts that I'm struggling with and receive input on them. Basically the code is a recursive DFS on a undirected graph that I'm supposed to convert to a concurrent program. My professor already specified that I should create my threads in the recursive DFS method and then join them in another method. Basically, I'm having trouble thinking of how I should keep track of the threads I'm creating so I can join all of them in the other method. I'm thinking an array of Threads but I'm unsure how to add each new thread to the array or even if that's the right direction.

• Android app crashes on second run

  - by Nick

  I have been working on my app and it runs on the simulator fine. I loaded it into my phone and now I have a problem. It runs fine when I first start it and also if I pick home and then restart it; however, if I use the back arrow and then restart it it crashes on that time, but will work out the next time I start it. I think it has to do with some kind of memory build up, but I verified onDestroy is being called, I figured that deletes everything my program created, right?

• dealing with IO vs pure code in haskell

  - by Drakosha

  I'm writing a shell script (my 1st non-example in haskell) which is supposed to list a directory, get every file size, do some string manipulation (pure code) and then rename some files. I'm not sure what i'm doing wrong, so 2 questions: How should i arrange the code in such program? I have a specific issue, i get the following error, what am i doing wrong? error: Couldn't match expected type [FilePath]' against inferred typeIO [FilePath]' In the second argument of mapM', namelyfileNames' In a stmt of a 'do' expression: files <- (mapM getFileNameAndSize fileNames) In the expression: do { fileNames <- getDirectoryContents; files <- (mapM getFileNameAndSize fileNames); sortBy cmpFilesBySize files } code: getFileNameAndSize fname = do (fname, (withFile fname ReadMode hFileSize)) getFilesWithSizes = do fileNames <- getDirectoryContents files <- (mapM getFileNameAndSize fileNames) sortBy cmpFilesBySize files

• Through Java, make a call to Javascript functions on networked device?

  - by stjowa

  I am doing device monitoring on a networked system. I need to know how to make Javascript calls on that device via its IP address to get certain status information (this device's status is only available through Javascript APIs, not SNMP, etc). I am working in Java. ADDED: The specific device is an Amino set-top-box. It has what it calls JMACX: JavaScript Media Access Control Extensions API specification. It allows you within an HTML document to use that API to get MUCH information about the device (cpu usage, channel info, remote-control options, etc.). I need to get this information within a Java program for specific monitoring purposes. Perhaps possible with HTTP requests? Any input would be greatly appreciated. Thanks, Steve

• How do you preserve the updated_at date field when saving the the database in Symfony?

  - by Failpunk

  This has to be simple... I'm trying to preserve the current date that is already stored in an updated_at field in the DB. I'm updating a single field value in the same row and then saving but I don't want it to update the updated_at field. I want to preserve the existing updated_at value. I only want to do this in one, maybe two situations so I don't need to overwrite the model for every other action in the program. I've tried this: $originalDate = $this->getUpdatedAt(); $this->setUpdatedAt($originalDate); $this->save(); This seems like it should work but still it seems to update the field.

• Android/Java Javadoc missing after updating Android SDK

  - by binnyb

  After i recently installed the new Android SDK stuff, I no longer can view the Javadoc while editing my project's code. I get this message: Note: This element has no attached source and the Javadoc could not be found in the attached Javadoc. I am getting this message for all methods, variables, classes, etc. I have installed the documentation and everything available to me via the android update manager. I have also tried to do a clean install of the android sdk and eclipse, and no luck getting the javadoc working. I have also tried manually setting the javadoc via project properties -> javadoc location -> file:/C:/Program Files/Android/android-sdk-windows/docs/reference/ with no luck What suggestions do you have that could fix this problem?

• PHP find if file data is an image

  - by Christian Sciberras

  Imagine I have some file data in a variable $data. I need to determine whether it is an image or not. No need for details such as corrupt images etc. Firs thought would be getting the file mime type by looking at the magic number and then see whether "image" is in the mime type. No such luck, even if I have a "file extension to mime type" script, I don't have a reliable way to get mime from magic number. My next option was to have a reasonable list of image file magic numbers and consult them. However, it relatively difficult to find such magic numbers (gif for instance has different magic numbers, some of which could pretty rare - if memory serves me right). A better idea would be some linux program which can do this kind of thing. Any ideas? I'm running RHEL and PHP 5.3. I've got root access - ie able to install stuff if needed. - Chris.

• What types of conditions can be used for conditional compilation in C++?

  - by user1002288

  This is an exam question for C++: Which of the following statements accurately describe the condition that can be used for conditional compilation in C++? A. The condition can depend on the value of environment variables. B. The condition can depend on the value of any const variables. C. The condition can depend on the value of program variables. D. The condition can use the sizeof() operator to make decision about compiler-dependent operations based on the size of standard data type. E. The condition must evaluate to either a 0 or 1 during preprocessing. I think the answer is E. Is this correct?

• How can I load an MP3 or similar music file for display and anaysis in wxWdigets?

  - by Jon Cage

  I'm developing a GUI in wxPython which allows a user to generate sequences of colours for some toys I'm building. Part of the program needs to load an MP3 (and potentially other formats further down the line) and display it to the user. That shuold be sufficient to get started but later I'd like to add features like identifying beats and some crude frequency analysis. Is there any simple way of loading / understanding an MP3's contents to display a plot of it's amplitudes to the screen using wxWidgets? I later intend to port to C++/wxWidgets for speed and to avoid having to distribute wxPython.

• What do I need to learn to make a website that can make a text file?

  - by lala

  I want to make a website, but all I know is basic HTML and CSS. On this website, I want the user to input in multiple text fields (sort of like they take a quiz) and then the program will make a text file based on the user input which the user can download. I want it to work backwards, too, so that the text file is the input. What do I need to learn to make a website to do this? Will javascript do the trick? I'm a beginning to intermediate programmer, mainly with java and I've learned some C# recently. I thought I could learn ASP.Net for this, but it turns out my hosting doesn't support it.

• Fractional Calculator in Java

  - by user2888881

  I am trying to create a fractional calculator in Java with inputs of mixed fractions, proper fractions, improper fractions or integers. It should include the four basic operators as well. The program should be set up as a loop where it is continuous until the user types "quit". I have coded the beginning loop but have no idea where to go from there. Please help, I am a beginner and would really appreciate it. Thank you again. This is what I have so far: import java.util.*; public class FractionCalculator { private static Scanner input; public static void main(String[] args) { input = new Scanner(System.in); String x = "quit"; System.out.println("Enter a fraction"); while (true) { String y = input.next(); if (y.equals(x)) { break; } } } }

• Need a field / flag / status number for mutliple use ?

  - by Jules

  I want to create a field in my database which will be easy to query. I think if I give a bit of background this will make more sense. My table has listings shown on my website. I run a program which looks at the listings a decides whether to hide them from being shown on the site. I also hide listings manually for various reasons. I want to store these reasons in a field, so more than one reason could be made for hiding. So I need some form of logic to determine which reasons have been used. Can anyone offer me any guidance on what will be future-proof aka new reasons and what will be quick and easy to query upon ?

• How do include paths work in Visual Studio?

  - by Paperflyer

  Visual Studio drives me crazy and I am suspecting I am doing something wrong. This is what I do: I installed Visual Studio (Pro '08) a long time ago, I installed the Windows SDK (Win 7 x64), someone emails me a project, it fails to build. Invariably, it can not find windows.h. While it is easy enough to include C:\Program Files\Microsoft SDKs\Windows\v7.0\Include in the project settings of every single project, I feel that this may not be the proper way to do it. Is there a way to somehow make Visual Studio globally aware of these files? I also tried to include the above directory in the path variable but that didn't change anything. Also, it will randomly find windows.h but not winresrc.h in the same directory.

• How to get into android phone without having to press any buttons

  - by user2961092

  I'm not a programmer, so I'm not sure what I'd needed to answer my question. I'm wondering if it's possible to program a way to half wake your cell phone screen without having to press any buttons or using the sensors. Like I've found you can do on the blackberry z10, you have an option to wake the screen by swiping up from a locked screen. I love android and will use it regardless, but I had to use a z10 for work for a while and stumbled upon that feature. It would be fantastic to have that feature with Android as hitting a power button can get annoying. Thanks in advance
