  • Asynchronous File I/O in .NET

    - by uno
    I followed the example at this link, Async I/O). The example works on my local machine. However when I deploy to my test machine - Windows Server 2003, It seems to work on 24 files and then the application stops. Procmon shows that its working on 24 files and then there is no data. My local machine is Windows XP. The question is why would this behave this drastically between XP and Windows 2003

  • How to assign a value of a property to a var ONLY if the object isn't null

    - by Blankman
    In my code, is there a shorthand that I can use to assign a variable the value of a object's property ONLY if the object isn't null? string username = SomeUserObject.Username; // fails if null I know I can do a check like if(SomeUserObject != null) but I think I saw a shorthand for this kind of test. I tried: string username = SomeUserObject ?? "" : SomeUserObject.Username; But that doesn't work.

  • PropertyChanged Event of ObservableCollection

    - by developer
    Hi All, I have a observable collection of viewmodel objects. How can I subscribe to the Property Changed event of each view model in my collection as they are created and track which ones have been changed, so that I can updated them to my database. List<DomainObject> objectsToSave = new List<DomainObject>(); foreach (Test val in dirtyObjs) { objectsToSave.AddRange(val.GetObjectsToSave()); } //DB changes bool saveSucceeded = DataServices.SaveMultiple(objectsToSave);

  • PHP's form bracket trick is to Django's ___?

    - by Matt
    In PHP you can create form elements with names like: category[1] category[2] or even category[junk] category[test] When the form is posted, category is automatically turned into a nice dictionary like: category[1] => "the input value", category[2] => "the other input value" Is there a way to do that in Django? request.POST.getlist isn't quite right, because it simply returns a list, not a dictionary. I need the keys too.

  • jQuery on iPhone/Android/BlackBerry

    - by Floetic
    I don't have any of the devices to test at the moment. I guess I'll start using the emulators later on. We're looking to offer mobile support. I was wondering how jQuery or even javascript renders in their respective browsers. What works? What doesn't? Any tips? Advice?

  • Why does this compile?

    - by akf
    I was taken aback earlier today when debugging some code to find that something like the following does not throw a compile-time exception: public Test () { HashMap map = (HashMap) getList(); } private List getList(){ return new ArrayList(); } As you can imagine, a ClassCastException is thrown at runtime, but can someone explain why the casting of a List to a HashMap is considered legal at compile time?

  • Rails-like console for PHP?

    - by Chad Johnson
    Every so often, things work in my local PHP development environment, while in my test environment on my server, things do not. It's a nightmare to debug this. If I had a console like Rails provides, debugging would be much much simpler. Is there anything like the Rails console but for PHP? I should mention that I am using a home-brewn PHP application.

  • Software testing terminology

    - by shiouming
    Let say I have written a small program that reads file_A and file_B as input data of test_case_A and test_case_B, passes the input to component_X which needs to be test, then verifies result against predefined expectation. That component_X could be in the same process, or different process on another machine. I try to learn more about testing, but confused by various terms. Take above scenario as example, which of them is fixture/mock/harness/stub? Thanks.

  • problem understanding templates in c++

    - by hidayat
    Template code is not compiled until the template function is used. But where does it save the compiled code, is it saved in the object file from which used the template function in the first place? For example, main.cpp is calling a template function from the file test.h, the compiler generates an object file main.o, Is the template function inside the main.o file? because template code is not inlined, is it?

  • Bash Script (Cygwin) to grep a logfile for multiple phrases and output a new file for each phrase.

    - by Chris
    Each logfile is titled based on the date it was created in the format YYYY-MM-DD.txt. I need to search each file for five different keywords and output five files prepended with the specific keyword and then the original logfile name. Example: Test-YYYY-MM-DD.txt grep -i -w 'keyword1' YYYY-MM-DD.txt Keyword1-YYYY-MM-DD.txt If it's also possible to email each new file to a different person, that would be helpful as well.

  • Unit tests and fixtures

    - by Wizzard
    We have a bunch of unit tests which test a lot of webpages and REST API services. Currently when our tests run it pulls from these pages live but this can take ages to run sometimes, and it also feels like the tests should be testing more of our code - not just relying on them being up and responding (if that makes sense..). Is it better practice to save a valid api response and with the unit tests load this in during setup? Thoughts?

  • Free SVN repo server without requiring a project

    - by Nathan Campos
    I want to know if there are any free Subversion repository hosting servers where you don't need to have a 'project' to host your C++ files in. I don't have a actual project, but I want to store my C++ in an SVN repository. I am looking for something like OpenSVN where you can upload your C++ files, but it requires you to have a project. Can you recommend a Subversion hosting service where you can upload your files to an account, rather than a project. Something like: http://www.test-svn.com/~nathanpc/
