  • Check and avoid if a char is being entered in a int

    - by John
    Hi.... This is a exremely stupid question but i need help with this.... I'm trying to make a small program that i made robust and needed some help with tht.... int num1; int num2 = 0; System.out.print("Enter number 1: "); num1 = kb.nextInt(); while(num2<num1) { System.out.print("Enter number 2: "); num2 = kb.nextInt(); } Number 2 has to be greater than number 1 Also i want the program to automatically check and ignore if the user enters a char instead of an int... Cause right now when a user enters lets say "r" instead of a number the program just exists....

  • Is there a Javadoc-like plugin for Xcode that automatically generates the doc template?

    - by Mark
    I'm aware of Doxygen to generate the documentation. What I'm looking for is quick way to insert documentation in Xcode similar to what Eclipse does when editing Java files. Let's say I have an objective-c method with a couple of arguments like this: -(NSInteger*) sumOf: (NSInteger*) one and:(NSInteger*) two {... In Eclipse, if you place the cursor above the method and type: /**<Enter> you get a Javadoc template pre-populated with @param and @return tags. Is it possible to achieve something similar in Xcode? After typing /**<Enter>, I'd like to get this automatically: /** * * @param one * @param two * * @return */ -(NSInteger*) sumOf: (NSInteger*) one and:(NSInteger*) two {...

  • C++ STL: Array vs Vector: Raw element accessing performance

    - by oh boy
    I'm building an interpreter and as I'm aiming for raw speed this time, every clock cycle matters for me in this (raw) case. Do you have any experience or information what of the both is faster: Vector or Array? All what matters is the speed I can access an element (opcode receiving), I don't care about inserting, allocation, sorting, etc. I'm going to lean myself out of the window now and say: Arrays are at least a bit faster than vectors in terms of accessing an element i. It seems really logical for me. With vectors you have all those security and controlling overhead which doesn't exist for arrays. (Why) Am I wrong? No, I can't ignore the performance difference - even if it is so small - I have already optimized and minimized every other part of the VM which executes the opcodes :)

  • [Erlang - trace] How to trace for all functions in an Erlang module except for one?

    - by Dlf
    I wanted to trace for all functions in an erlang module, with dbg:tpl, but one of the internal functions took up 95% of the trace file. I then wanted to exclude only that single function and found that it was not as easy as I thought it would be. I know there are great pattern matching possibilities for arguments when tracing. Is there a similar possibility to apply pattern matching for functions? eg.: {'=/=', '$2', function_name} I am open for outside-the-box solutions as well! Thank You!

  • int vs const int&

    - by Valdo
    I've noticed that I usually use constant references as return values or arguments. I think the reason is that it works almost the same as using non-reference in the code. But it definitely takes more space and function declarations become longer. I'm OK with such code but I think some people my find it a bad programming style. What do you think? Is it worth writing const int& over int? I think it's optimized by the compiler anyway, so maybe I'm just wasting my time coding it, a?

  • Using a database/index sequential file independently of the Unix distribution

    - by Helper Method
    What I'm planning to do is a) parse a file for some lines matching a regular expression b) store the match in some sort of database / file so I don't have to do the parsing again and again c) call another program passing the matches as arguments While I can imagine how to do a) and c), I'm a little bit unsure about b). The matches are of the form key:attribute1:attribute2:attribute3 where attribute 2 may be optional. I'm thinking of storing the results in a simple database but the problem is the database needs to available on a number of Unix platform for the program to work. Are there any (simple) databases which can be found on any Unix platforms? Or should I use some sort of index-sequential file?

  • What's the difference between => , ()=>, and Unit=>

    - by Malvolio
    I'm trying to represent a function that takes no arguments and returns no value (I'm simulating the setTimeout function in JavaScript, if you must know.) case class Scheduled(time : Int, callback : => Unit) doesn't compile, saying " `val' parameters may not be call-by-name" case class Scheduled(time : Int, callback : () => Unit) compiles, but has to be invoked strangely, instead of Scheduled(40, { println("x") } ) I have to do this Scheduled(40, { () => println("x") } ) What also works is class Scheduled(time : Int, callback : Unit => Unit) but is invoked in an even-less-sensible way Scheduled(40, { x : Unit => println("x") } ) (What would a variable of type Unit be?) What I want of course is a constructor that can be invoke the way I would invoke it if it were an ordinary function: Scheduled(40, println("x") ) Give baby his bottle!

  • Multiple Inheritance Debates II: according to Stroustrup

    - by asksuperuser
    I know very well about the traditional arguments about why Interface Inheritance is prefered to multiple inheritance, there has been already a post here : http://stackoverflow.com/questions/191691/should-c-include-multiple-inheritance But according to Stroustrup the real reason why Microsoft and Sun decided to get rid off multiple inheritance is that they have vested interest to do so: instead of putting features in the languages, they put in frameworks so that people then become tied to their platform instead of people having the same capability at a language standard level. What do you think ? Why Sun and Microsoft consider developers too immature to just make the choice themselves ?

  • What is XML good for and when should i be using it?

    - by Haroldo
    I'm curious, I've been developing pretty powerful websites/web apps, and I've never learnt XML, even odder I've never really felt the need to. It's not like Curl or Prepared Statements where before knowing what they did and how they worked I had a feeling 'there's got to be an easier way to do this!' or 'there's got to be something designed for this!'. Currently I work with MySQL and JSON and I don't have this feeling of 'I need to learn that' (XML), this must be wrong! I'm really interested to hear some compelling arguments for XML, and learn about things which it can do beter than JSON or MySQL (or some other aspect of web dev) and when i should be using it!

  • Is there a way to use jquery without using the $ - accessor?

    - by ManBugra
    I'am dealing here with a web application that defines somewhere in a java script file: $ = function() { return document.getElementById(arguments[0]); } Every other script, jsp page and dynamic content loaded from db depends on the semantic of the $ - sign working as 'document.getElementById'. Now i would like to start using jqery. So i think i have 2 options: refactor the existing application (all script files, jsp's, dynamic content etc.) somehow introduct jquery as something differnt than '$' (not really an option) don't start using jquery Are there any other solutions? What would you do?

  • Constructors + Dependency Injection

    - by Sunny
    If I am writing up a class with more than 1 constructor parameter like: class A{ public A(Dependency1 d1, Dependency2 d2, ...){} } I usually create a "argument holder"-type of class like: class AArgs{ public Dependency1 d1 { get; private set; } public Dependency2 d2 { get; private set; } ... } and then: class A{ public A(AArgs args){} } Typically, using a DI-container I can configure the constructor for dependencies & resolve them & so there is minimum impact when the constructors need to change. Is this considered an anti-pattern and/or any arguments against doing this?

  • Applescript - Get status of windows ( Visible or in the dock )

    - by user1329172
    I need some help for my appleScript. For all open windows, I want to know which one is hidden (in the dock), which one is visible and which one is focused? To list windows I use : tell application "System Events" set procs to processes set windowName to {} repeat with proc in procs try if exists (window 1 of proc) then repeat with w in windows of proc copy w's name to the end of windowName end repeat end if end try -- ignore errors end repeat end tell return windowName I tried focused property: copy w's focused to the end of windowName and selected property: copy w's selected to the end of windowName But this doesn't work! Thanks for help!

  • python-wordmatching

    - by challarao
    Write two functions, called countSubStringMatch and countSubStringMatchRecursive that take two arguments, a key string and a target string. These functions iteratively and recursively count the number of instances of the key in the target string. You should complete definitions for def countSubStringMatch(target,key): and def countSubStringMatchRecursive (target, key): For the remaining problems, we are going to explore other substring matching ideas. These problems can be solved with either an iterative function or a recursive one. You are welcome to use either approach, though you may find iterative approaches more intuitive in these cases of matching linear structures.

  • Problem Making C++ script

    - by Abs
    Hello all, I am not sure if I can post this sort of question (apologies in advance) but I am trying to build something from this blog post. # mkdir wkthumb # cat > wkthumb.cpp # qmake -project # qmake && make # ./wkthumb I have no experience with this, but I download all the files needed in the directory wkthumb using git. I have gone inside this directory and tried to execute cat > wkthumb.cpp - this just hangs for me. In addition, I thought cat was supposed to be used like this: cat file1.txt file2.txt > file3.txt? The above is blank with the first arguments? I am using Fedora Core 10.

  • Using Jquery 1.8.0 return false is not breaking an each() loop

    - by user1879729
    Here is the script I am using. $('.row').each(function(){ $(this).each(function(){ if($(this).find('.name').val()==""){ $(this).find('.name').val(data.name); $(this).find('.autonomy').val(data.autonomy); $(this).find('.purpose').val(data.purpose); $(this).find('.flow').val(data.flow); $(this).find('.relatedness').val(data.relatedness); $(this).find('.challenge').val(data.challenge); $(this).find('.mastery').val(data.mastery); $(this).find('.colour').val(data.colour); done=true; } if(done==true){ alert("here"); return false; } }); }); It just seems to totally ignore the return false and I can't seem to work out why!

  • How to use multiple restrictions in C# Generics properly?

    - by plouh
    I am attempting to bind c# generics to a class and an interface like this: public class WizardPage<T> where T : UserControl, IWizardControl { private T page; public WizardPage( T page ) { this.page = page; } } And use it with this: public MyControl : UserControl, IWizardControl { //... } Somehow C# doesn't seem to be able to decide that MyControl is a proper instance of T as public class Wizard<T> where T : UserControl, IWizardControl { private WizardPage<T> Page1; public Wizard( MyControl control ) { this.Page1 = new WizardPage(control); } } fails with error The best overloaded method match for 'Controls.WizardPage.WizardPage(T)' has some invalid arguments Am I doing something wrong or is this just not going to work?

  • Smallest Java Runtime I can legally distribute?

    - by Mark
    My Java SWT desktop application is distributed with it's own Java runtime and I want to make the download size as small as possible. I'd like to remove all the classes I don't use from rt.jar, but this is forbidden according to JDK runtime licence (see the README.html file in the root JDK folder). Since Java is open source, am I allowed to compile my own 'Java' runtime from source which doesn't have this distribution restriction? If so, has anyone done this already? (Or do you just ignore the JDK licence terms?)

  • CouchDB emit with lookup key that is array, such that order of array elements are ignored.

    - by MatternPatching
    When indexing a couchdb view, you can emit an array as the key such as: emit(["one", "two", "three"], doc); I appreciate the fact that when searching the view, the order is important, but sometimes I would like the view to ignore it. I have thought of a couple of options. 1. By convention, just emit the contents in alphabetical order, and ensure that looking up uses the same convention. 2. Somehow hash in a manner that disregards the order, and emit/search based on that hash. (This is fairly easy, if you simply hash each one individually, "sum" the hashes, then mod.) Note: I'm sure this may be covered somewhere in the authoritative guide, but I was unsuccessful in finding it.

  • Best way to test class methods without running __init__

    - by KenFar
    I've got a simple class that gets most of its arguments via init, which also runs a variety of private methods that do most of the work. Output is available either through access to object variables or public methods. Here's the problem - I'd like my unittest framework to directly call the private methods called by init with different data - without going through init. What's the best way to do this? So far, I've been refactoring these classes so that init does less and data is passed in separately. This makes testing easy, but I think the usability of the class suffers a little.

  • Visual studio 2010 doesn't make the changes when i do a build/compile

    - by Tom
    Ok so i change some code, re-build it and then, say for arguments sake i had a print statement outputting 'test2', well if i change it to 'test3' its still re-producing the old code 'test2'. Ive deleted the debug folder and rebuilt but no good. Then randomly about 10 builds later it will catch up. Ive also closed VS2010 and then re-opened the project but that doesnt help. What can i do as i need to see the changes asap? ps it's definitely the correct file

  • Can a raw Lucene index be loaded by Solr?

    - by wynz
    Some colleagues of mine have a large Java web app that uses a search system built with Lucene Java. What I'd like to do is have a nice HTTP-based API to access those existing search indexes. I've used Nutch before and really liked how simple the OpenSearch implementation made it to grab results as RSS. I've tried setting Solr's dataDir in solrconfig.xml, hoping it would happily pick up the existing index files, but it seems to just ignore them. My main question is: Can Solr be used to access Lucene indexes created elsewhere? Or might there be a better solution?

  • the problem of redirecting stdout in c#

    - by Mher
    Could you please explain why the shell redirection doesn't work with System.Diagnostics.Process class? I am trying to redirect the output streams to file with the following snippet: Process p = new Process(); p.StartInfo = new ProcessStartInfo(); p.StartInfo.FileName = "java.exe"; p.StartInfo.Arguments = @"> c:\Temp\test.log 2>&1"; p.StartInfo.UseShellExecute = true; p.Start(); The similar code works without problems with Python. Reading the output streams programmatically doesn't seem a preferable solution in my case because there will be a bunch of processes launched by my application.

  • Any way to not break on certain errors in Visual Studio 2010?

    - by Vulgrin
    I'm working on a VS2010 project where I'm using DataAnnotations on my objects to handle validation. However, this is sort of a pain in the butt while trying to do interactive debugging because it keeps pausing VS.Net on validation errors. Obviously, I want to break on some errors, but not these particular types. Am I out of luck and I just need to turn on and off my Break on All Errors setting? Or is there some way to tell VS to just ignore these when they happen? (these are errors generated via Validator.ValidateProperty calls.) Thanks
