  • directory_map() not working outside of application

    - by iamdadude
    Is there a reason as to why $map = directory_map('./', TRUE); works perfectly and, $map = directory_map('../', TRUE); doesn’t work at all? I tried creating a directory with the basic mkdir(); PHP function (http://php.net/mkdir) and it didn’t work either. Can anyone set me in the right direction as to what I’m doing wrong and how I can fix it? Thanks!

  • Chat app vs REST app - use a thread in an Activity or a thread in a Service?

    - by synic
    In Virgil Dobjanschi's talk, "Developing Android REST client applications" (link here), he said a few things that took me by surprise. Including: Don't run http queries in threads spawned by your activities. Instead, communicate with a service to do them, and store the information in a ContentProvider. Use a ContentObserver to be notified of changes. Always perform long running tasks in a Service, never in your Activity. Stop your Service when you're done with it. I understand that he was talking about a REST API, but I'm trying to make it fit with some other ideas I've had for apps. One of APIs I've been using uses long-polling for their chat interface. There is a loop http queries, most of which will time out. This means that, as long as the app hasn't been killed by the OS, or the user hasn't specifically turned off the chat feature, I'll never be done with the Service, and it will stay open forever. This seems less than optimal. Long question short: For a chat application that uses long polling to simulate push and immediate response, is it still best practice to use a Service to perform the HTTP queries, and store the information in a ContentProvider?

  • Why doesn't Win Forms application update label immediately?

    - by rosscj2533
    I am doing some experimenting with threads, and made a 'control' method to compare against where all the processing happens in the UI thread. It should run a method, which will update a label at the end. This method runs four times, but the labels are not updated until all 4 have completed. I expected one label to get updated about every 2 seconds. Here's the code: private void button1_Click(object sender, EventArgs e) { Stopwatch watch = new Stopwatch(); watch.Start(); UIThreadMethod(lblOne); UIThreadMethod(lblTwo); UIThreadMethod(lblThree); UIThreadMethod(lblFour); watch.Stop(); lblTotal.Text = "Total Time (ms): " + watch.ElapsedMilliseconds.ToString(); } private void UIThreadMethod(Label label) { Stopwatch watch = new Stopwatch(); watch.Start(); for (int i = 0; i < 10; i++) { Thread.Sleep(200); } watch.Stop(); // this doesn't set text right away label.Text = "Done, Time taken (ms): " + watch.ElapsedMilliseconds; } Maybe I'm just missing something basic, but I'm stuck. Any ideas? Thanks.

  • How do develop a Java web application without having to deploy all the time

    - by ChrisSmith..zzZZ
    I've set up a simple Eclipse 3.5/Jetty 6.1 web app which returns hello world. It works. This is on Windows and uses the "Jetty Generic Server Adapter". I have auto deployment working so that it deploys after changes periodically. How do I go about setting it up so that if I change any static content it doesn't have to redeploy i.e I can just hit F5 to see the changes straight away. For minor HTML changes it's quite unusable waiting 20-30 seconds for a deployment.

  • Android Icon Duplicates in Application Dock

    - by datguywhowanders
    For some odd reason, my project is generating two icons, same name, launches the same project, in the app drawer. I can't figure out what is causing this. Does anyone have any suggestions? Link to screenshot The M in the white circle is my default icon. If you view the screenshot, you'll see it appears twice. I've checked the applications area, and it is only installed once.

  • Android: how to start a service at boot based on user-settings?

    - by Cicerone Cojocaru
    Hey everyone, I'm trying to write an app that consists of an activity that manages a background service. However, I want to implement a user setting for automatically starting the service up at boot time. I have user settings implemented with SharedPreferences and I have the services starting up at boot by using a BroadcastReceiver and listening for BOOT_COMPLETED. However, I can't figure out a good way to implement a setting so that the service is only started at boot if said setting is enabled. I can think of a few cheap ways to do this (such as messing with onCreate() in the service, or creating/checking for a file on SD card) but I want to follow good practice. There must be a good way to do this because there's tons of apps out there that do it, I just can't find anything online about how to do it. Thanks

  • undefined method `model_name' for NilClass:Class - Rails application

    - by user1270259
    So I have seen other articles here on stack about this and a lot of the time people are not doing @post = post.new. I read some where to use the plural...?? any ways I am getting this error on my discussion code: Discussion Controller class DiscussionsController < ApplicationController def index @discussion = Discussion.new @discussions = Discussion.all end def create @discussion = Discussion.create(params[:discussion]) if @discussion.save redirect_to tasks_path, :flash => {:success => 'Created a new discussion'} else redirect_to tasks_path, :flash => {:error => 'Failed to create a discussion'} end end end Discussion Form <%= form_for @discussion do |f| %> <p><%= f.label :title %> <%= f.text_field :title %></p> <p><%= f.label :content %> <%= f.text_area :content %></p> <% end %> Discussion Routes resources :discussions do resources :comments end Now as far as I know I am doing this right, because I have a task form set up essentially the same way - but I have looked at my code for hours and have googled and tried other examples and now i see this: undefined method `model_name' for NilClass:Class Extracted source (around line #1): 1: <%= form_for @discussion do |f| %> 2: 3: <p><%= f.label :title %> 4: <%= f.text_field :title %></p> Which should mean that I am missing something from my controller.....is it as asilly as a spelling mistake? .

  • Load all tab bar views when application first runs

    - by codenoobie
    Here's the problem. I have a tab bar controller with 4 separate views. When I navigate from the first view to the second view, it takes some time to load up the second view. What I want to do is be able to load and initialize all of my tab bar views during my splash screen. That way, when the user navigates between the tab views, there is no wait time. So the question is... how do I manually initialize my individual tab bar views in my app delegate? And once again, thank you stackoverflow!

  • Is keeping uploads folder outside of 'public_html' enough to keep my application secure from malicio

    - by ecu
    Although I realise there are different approaches to securing upload process, I'm still confused when it comes to basic principles. I want to allow users to upload any kind of file they want, but keep my app secure. So my question is: Is it sufficient to store the files with their original names in 'uploads' folder outside 'webroot' and fetching them via some download.php script? If it't not secure enough, please point me in the right direction, or suggest what additional steps I should take to make it safe. Thank you.

  • Windows service installed successfully but not responding after started.

    - by Ridhi
    I have a windows service written in C#, .Net framework 2.0. I installed it on three machines and it worked fine but on one machine (with .Net framework 2.0) the setup has installed the service successfully but the service is not responding after I start it. I check for this by checking whether a log file is created at a specific path insribed in the config file or not. This log file is created everytime the timer elapses the interval time. I'm unable to figure out the reason. Have checked all the parameters but unable to get any solution to this. The funny thing is that the same setup is running well on other machines. P.S.: I have admin access on all the servers I'm installing this service on.

  • Visual C++ application/libarary size anomoly

    - by Tim Ring
    This is just a bit of a general question regading app/lib file sizes. When I build a particular library in my C++ solution I notice that the .lib file size is larger in the release build than in the debug (1.2mb Vs 800k). However when I build an app in the same solution, using the aforementioned library, the release .exe is always smaller (as I'd expect) than thew debug .exe (50k vs 200k). I would always have expected the release verisons of anything to be smaller than the debug versions. What gives?

  • Suggestions on including free database products to include in an application - SQL Server Express or

    - by superartsy
    I am working on an enterprise level product that is designed around SQL Server Express and specifically its features (views, concurrent users, stored procedures, CASE and IF statements). Though we don't use any advanced SQL Server features, the database size limit of 4GB in the Express edition may up being a limitation. A work-around is that customers can move to more full-featured versions of SQL Server. The problem is that SQL Server Express deployment is not easy, and the installer size is huge. This is a major drawback for someone looking to try our product. You don't want end-users to not buy a product because the download is huge. Does anyone have any recommendations of a database that has a smaller footprint but all the features of Express and which can be migrated to express?

  • Is it possible to create a Service that listens for hardware key presses?

    - by VoteBrian
    I'd like to run an Android background service that will act as a keylistener from the home screen or when the phone is asleep. Is this possible? From semi-related examples online, I put together the following service, but get the error, "onKeyDown is undefined for the type Service" public class ServiceName extends Service { @Override public void onCreate() { //Stuff } public IBinder onBind(Intent intent) { //Stuff return null; } @Override public boolean onKeyDown(int keyCode, KeyEvent event) { if(event.getAction() == KeyEvent.ACTION_DOWN) { switch(keyCode) { case KeyEvent.KEYCODE_A: //Stuff return true; case KeyEvent.KEYCODE_B: //Stuff return true; //etc. } } return super.onKeyDown(keyCode, event); } } I realize Android defaults to the search bar when you type from the home screen, but this really is just for a very particular use. I don't really expect to distribute this. Also, it'd be nice to use the camera button to wake the phone.

  • [ADVICE] .NET Desktop Application - Client Server C#, SQL

    - by Rillanon
    Hi guys, Recently I've being given a chance to develop a PMS (Practice Management System) software for a small physiotherapy clinic. I'm a computer science student and my course is predominately told on Linux. However, my client runs all their computers on vista or Windows 7. My ideas are to develop the client front end in Visual C# and access a central postgresql server. I'm a beginner in Windows Programming so I'm after advice on best practice on implement user rights and access levels in C# (WPF or Windows FORM). I've had a look into Credential class in Visual C# and access control list but please share your thoughts. I'm probably way over my head on this but this is my first commercial project so I'm keen to test the waters. Cheers Ian
