  • Where does abort() and terminate() "live"?

    - by user325016
    Regarding the terminate handler, As i understand it, when something bad happens in code, for example when we dont catch an exception, terminate() is called, which in turn calls abort() set_terminate(my_function) allows us to get terminate() to call a user specified function my_terminate. my question is: where do these functions "live" they don't seem to be a part of the language, but work as if they are present in every single cpp file, without having to include any header file.

  • How to find where program crashed

    - by Mick
    I have a program that crashes (attempting to read a bad memory address) while running the "release" version but does not report any problems while running the "debug" version in the visual studio debugger. When the program crashes the OS asks if I'd like to open up the debugger, and if I say yes then I see an arrow pointing to where I am in a listing of some assembler which I am not skilled enough to read properly (I learned 6502 assembler 30 years ago). Is there any way for my to determine where in my sourcecode the offending memory read was located?

  • What exactly do "IB" and "UB" mean?

    - by cHao
    I've seen the terms "IB" and "UB" used several times, particularly in the context of C++. I've tried googling them, but apparently that two-letter combination sees a lot of use. :P So, i ask you...what does it mean, if it's said like it's a bad thing?

  • Is it possible to set a default behaviour for custom (non-native) methods/functions in Java?

    - by Tom
    Is it possible to set a default behaviour for custom (non-native) methods/functions in Java? For example, I would like to change the default "Function" to do a System.out.println("message") whenever called. So, when a custom method/function is being created: public String testMethod() { //custom code } it should execute the newly added default behaviour (in this case the system output), before the custom code is run. Even if this would be a bad excercise, is it possible? Maybe by extending the function class or something?

  • IoC.Resolve vs Constructor Injection

    - by Omu
    I heard a lot of people saying that it is a bad practice to use IoC.Resolve(), but I never heard a good reason why (if it's all about testing than you can just mock the container, and you're done). now the advantages of using Resolve instead of Constructor Injection is that you don't need to create classes that have 5 parameters in the constructor, and whenever you are going to create a instance of that class you're not gonna need to provide it with anything

  • Wrapper class for HttpGet / Post in Java?

    - by Tim Green
    Hi, Sorry, I'm quite new to Java. I've stumbled across HttpGet and HttpPost which seem to be perfect for my needs, but a little long winded. I have written a rather bad wrapper class, but does anyone know of where to get a better one? Ideally, I'd be able to do String response = fetchContent("http://url/", postdata); where postdata is optional. Thanks!

  • countering a div opacity?

    - by Jason94
    If I have a div that acts like a box, and I make it real sexy with 10% opacity. How do I counter it since everything in the div also gets the opacity. Lets say i have a box(div) with a 1px border and text, putting opacity on it will make it look bad and i only want opacity on the background.

  • WPF DataGrid Get All SelectedRows

    - by anvarbek raupov
    Have to use free WPF DataGrid (I thought Infragistics libraries are bad, I take it back after this) for this project of mine. Looks like DataGrid doesnt have clean MVVM Friendly way of getting the list of selectedRows ? I can data bind to SelectedItem="{Binding SelectedSourceFile}" but this only shows the 1st selected row. Need to be able to get all selected rows. Any hints to do it cleanly via MVVM ?

  • Clean Stack Traces in Groovy using Eclipse?

    - by yar
    I am using Groovy in a Java Swing application as part of my plan to force-feed myself dynamic languages until I like them (which is happening, partly). My stack traces are filled with Groovy stuff like org.codehaus.groovy.runtime.callsite.ConstructorSite$ConstructorSiteNoUnwrapNoCoerce.callConstructor is there a way to get Eclipse to remove all of that codehaus stuff (filter stack traces, basically)? Edit: I can do this from the command-line with grep (well, not yet) so it's not so bad, but inside of Eclipse would be great too.

  • Running cUrl cmd from Win7 doesn't work, but on Linux it does.

    - by jkidv
    Like the title says. I'm sending a simple cUrl cmd from Win7 to CouchDB on my Linux box, and it doesn't work. But if I run the same command in Linux, it works. I'm sending this: curl -X POST 192.168.2.5:5984/test/testdoc -d '{"owner":{"fname":"test","lname":"ing"}}' From windows, it keeps giving me a "error: bad request, reason:invalid UTF-8 JSON". I can run GET commands from windows just fine, I just can't seem to POST to CouchDB.

  • Can I stop Uri from unencoding a url in WebRequest.Create?

    - by Paul
    The code itself isn't complex, it's just not working properly: Uri uri = new Uri("https://www.google.com/webmasters/tools/feeds/sites/http%3A%2F%2Fwww.mydomain.co.uk%2F"); WebRequest.Create(uri); I get a "Bad Request" back from the server, and after much MUCH digging, discovered that the uri is being turned in to "https://www.google.com/webmasters/tools/feeds/sites/http%3A//www.mydomain.co.uk/" which is not what I asked for, and so it's having a whinge Is there a way to stop this?

  • try .. catch blocks - when to use

    - by Konrad
    I have always been of the belief that if a method can throw an exception then it is reckless not to protect this call with a meaningful try block. I just posted 'You should ALWAYS wrap calls that can throw in try, catch blocks.' to this question and was told that it was 'remarkably bad advice' - I'd like to understand why. Thanks!

  • SEO - List of links

    - by Rafael Carvalho
    I'd like to know if listing a set of partner sites/blogs is useful for the pagerank growth. Does Google see it as an incorrect act? I read somewhere that if people exchange links, google seeks it and marks as a bad technique. If it doesn't matter, is the content of the linked site relevant?

  • JRuby-friendly method for parallel-testing Rails app

    - by Toby Hede
    I am looking for a system to parallelise a large suite of tests in a Ruby on Rails app (using rspec, cucumber) that works using JRuby. Cucumber is actually not too bad, but the full rSpec suite currently takes nearly 20 minutes to run. The systems I can find (hydra, parallel-test) look like they use forking, which isn't the ideal solution for the JRuby environment.

  • Strategy to rename the require_once function?

    - by openfrog
    Rather than just writing a new function called import() i'd like to know if there's a better solution. Otherwise require_once would be included in the scope of import() only, which is bad for any "global" variable there. My import() function would work differently than require_once, but serves the same purpose (enhanced usability).

  • Best solution for a windows service with constant running threads in C# 4.0

    - by dagda1
    Hi, I want to create a windows service that will create x number of threads that wake up every x number of minutes and do some work. I think the task scheduling or parallel framework is a bad fit for this type of work as it is best suited for work that starts, completes and finishes rather than is constant. Should I look at utilising a thread pool for this approach or does anyone have any advice for a good solution? Thanks Paul
