  • Does it should be in a namespace?

    - by Knowing me knowing you
    Do I have to put code from .cpp in a namespace from corresponding .h or it's enough to just write using declaration? //file .h namespace a { /*interface*/ class my { }; } //file .cpp using a::my; // Can I just write in this file this declaration and // after that start to write implementation, or // should I write: namespace a //everything in a namespace now { //Implementation goes here } Thanks.

  • Odd behaviour with scala method syntax

    - by Ceilingfish
    Hi chaps, I hit a bit of a quirk of scala's syntax I don't really understand object Board { def getObjectAt(x:Int, y:Int):Placeable = return locations(x)(y) } works fine. But object Board { def getObjectAt(x:Int, y:Int):Placeable { return locations(x)(y) } } returns the error Board.scala:8: error: illegal start of declaration return locations(x)(y) I found some stuff that says the second form convinces the scala compiler you're trying to specify an expansion to the return type Placeable. Is there a way I can fix this, or should I just avoid specifying a return type here?

  • Having multiple 'sets' of open files in Netbeans

    - by edorian
    I'd like to be able to have multiple "sets" of open files in netbeans but i didn't find a way or plugin to do it. Say i have 5 file related to "bug xyz" but i want to start working on feature "abc". Instead of having 10 files open i'd like to be able to say "create new set of files" and work on those and switch back and forth. Is there some way it netbeans to achieve this ?

  • Python Logging across multiple classes and files; how to configure so as to be easily disabled?

    - by mellort
    Currently, I have osmething like this in all of my classes: # Import logging to log information import logging # Set up the logger LOG_FILENAME = 'log.txt' logging.basicConfig(filename=LOG_FILENAME,level=logging.DEBUG) This works well, and I get the output I want, but I would really like to have all this sort of information in one place, and be able to just do something like import myLogger and then start logging, and then hopefully be able to just go into that file and turn off logging when I need an extra performance boost. Thanks in advance

    What are the best or most useful dev-related PowerShell modules that exist today? Not looking for sys admin management tools for Active Directory/Microsoft Exchange/etc., but more for development utilities. Please list one module per answer, so they can be voted up accordingly. I'll provide a few to start off.

  • trigger animation with timer, as3

    - by VideoDnd
    How do I trigger the animation in sync with my timer?My timer and flip animation work, but they are out of sync with each other. I'm lost with the IF ELSE statements. Each time the value of my textfield changes, my number needs to flip. See example. Example //IF ELSE FUNCTION function theFlip(event:TimerEvent):void { count++; if (count < 9) { oldcount = count - 1; } else { count++; fcount=int(count) count++; oldcount = count - 1; } } //Cont... Complete Codehere's the file //Timer var timer:Timer = new Timer(100); //Integer values var count:int = 0; var fcount:int = 0; var oldcount:int = 0; //Formatting String function formatCount(i:int):String { var fraction:int = i % 100; var whole:int = i / 100; return ("00" + whole).substr(-2, 2) + "." + (fraction < 10 ? "0" + fraction : fraction); } //Start the timer timer.start(); timer.addEventListener(TimerEvent.TIMER, theFlip); //IF ELSE FUNCTION function theFlip(event:TimerEvent):void { count++; if (count < 9) { oldcount = count - 1; } else { count++; fcount=int(count) count++; oldcount = count - 1; } var toText:String = formatCount(fcount); sec4.digit.text = toText.substr(4, 1); flip4.flip.digit.text = toText.substr(4, 1); flip4.gotoAndPlay(2); sec3.digit.text = toText.substr(3, 1); flip3.flip.digit.text = toText.substr(3, 1); flip3.gotoAndPlay(2); sec1.digit.text = toText.substr(1, 1); flip1.flip.digit.text = toText.substr(1, 1); flip1.gotoAndPlay(2); }

  • Where to begin with multi-threaded programming with c++?

    - by zoke
    I'm trying to implement my own IRC client as a personal proejct and I realized I needed a way to read and write from the socket at the same time. I realized I could have a reading thread which reads from the socket in the background and puts data in a queue and I could have another thread which writes data from a queue to the socket. However I have no idea on how to start with multithreaded programing or how to do it with c++. Where do I go from here?

  • What is some good software for designing MySQL databases?

    - by franzferdinand
    As above. Usually at work someone else does the database design, and when I do personal projects they're small enough to not really require more than five or six tables, but I'm about to start a personal project that I think will probably require around eleven or twelve tables and I'd like something to help me design it neatly and keep track of it.

  • Why is Visual Basic used?

    - by Arrieta
    I don't mean to start a holy war here, but I cannot fathom why would anybody use Visual Basic for a new project. Can you explain me why is it used? What new applications (which a lay person may be familiar with) have been developed in it? Why is it chosen over other languages? Thanks.

    - by hveveris
    Hello! Client wants some tricky stuff and i don't really know where to start with it. The idea is that there is a horizontal scrollView whose each page consists of a vertical scrollView. For example, on the horizontal axis there are galleries, on the vertical we scroll through selected gallery's images. Is this even possible? I'd be very glad to hear comments on this one!

  • "ejb not bound" -- What could be the problem?

    - by Bernhard V
    Hi! When I'm running my program, I get the following error: ... nested exception is javax.naming.NameNotFoundException: ejb not bound The error occurs at the start up when Java wants to create a certain bean. The Bean is a SimpleRemoteStatelessSessionProxyFactoryBean. Could it be that I ain't got the rights to access the naming provider URL although I can ping it? When accessing the bean on my local JBoss there are no problems.

    - by SepiDev
    I need to know how to start writing an application based on plug-in architecture. I mean how to write a base code an let others develop the application by adding the plug-ins they write. I know that there is some problems in doing such in c++. most people use another language such as python to add plug-ins to their c++ application.
