  • unprotected access to member in property get

    - by Lenik
    I have a property public ObservableCollection<string> Name { get { return _nameCache; } } _nameCache is updated by multiple threads in other class methods. The updates are guarded by a lock. The question is: should I use the same lock around my return statement? Will not using a lock lead to a race condition?

  • Access "currentState" from other classes?

    - by Herter
    I'm making a little application in Actionscript 3. In my initApp.as I have created another class which needs to edit the currentState, which is only accessible from the main .as (initApp.as). I found a solution such that I can reach the currentState property from my other class: Application.application.currentState. This is however not a good solution as it couples the classes too much.. is there a better way of editing the currentState from other classes?

  • vim - open file with complete path

    - by David Oneill
    If I have a file that contains a complete path for a file, is there a way to highlight the filename (using visual mode) and open the file? (preferably in a split screen) As I think about it, here is what I would like: if the file name contains a / character, assume it is a full path (IE the 'current directory' is root). Otherwise, use the current folder (IE default behavior) Is this possible?

I tried putting HomeViewController.LAT but obviously that does not work, I'm pretty new to the language so I am confused.

  • Gain Access to Mouse Clicks in C# Component

    - by Jason
    I am using the ScintillaNET component and I am attempting to capture clicks in the margin, as this will determine how I respond. Unfortunately, the margins capture the mouse events (and don't provide a way, from what I can see, to get the click information - number of clicks, mouse button clicked, etc). If this is indeed the case (I am not able to get that info directly), what is another way of capturing what the mouse is doing before the MarginClick event is fired? Thanks for any help!

    I'm trying to write a short file filtering code in Python that will find my desired string. I've got it worked out logically, but my Command Feed is sending me an error message for the print statement. This is how it works as of now: filename = input('give file name: ') n = input('give desired string: ') f = open line = f.readline() while line: if n in line: print line line = f.readline() Error Statement: Traceback (most recent call last): File "<string>", line 7, in <fragment> Syntax Error: print line: <string>, line 718 I know this is a simple problem but the answer is not obvious to me. please help.

  • Access Ruby on Rails 'public' directory without relative path

    - by huntca
    I have a flash object I wish to load and I belive the best place to store that asset is in the public directory. Suppose it's stored in public/flash, there must be a better way to path to the swf than what I've done below. Note the 'data' element, it has a relative path. def create_vnc_object haml_tag :object, :id => 'flash', :width => '100%', :height => '100%', :type => 'application/x-shockwave-flash', :data => '../../flash/flash.swf' do haml_tag :param, :name => 'movie', :value => '../../flash/flash.swf' end end Is there some rails variable that points to public?
