  • Is JSON array parsable?

    - by Alex
    I have a YQL query that extracts data from a page and returns it to my script as JSON. The JSON is huge, and as such, here's my question: Is JSON array parsable? So that I can iterate over the entire JSON structure?

  • Why does it not allowed to use try-catch statement without {} ?

    - by alex
    Why can't I use code like this ? 1 int i = 0; try i = int.Parse("qwerty"); catch throw; 2 try i = int.Parse("qwerty"); catch; finally Log.Write("error"); And should write like this 1 int i = 0; try { i = int.Parse("qwerty"); } catch { throw; } 2 try { i = int.Parse("qwerty");} catch {} finally {Log.Write("error");} PS: I can use if-else statement without {}. Why should I use them with try-catch(-finally) statement ? Is there any meaningful reason ? Is it only because that some people think that code is hard to read ? Several months ago I asked that question on russian programming forum but I got no satisfactory answer ...

  • How to install the program depending on libstdc++ library

    - by Alex Farber
    My program is written in C++, using GCC on Ubuntu 9.10 64 bit. If depends on /usr/lib64/libstdc++.so.6 which actually points to /usr/lib64/libstdc++.so.6.0.13. Now I copy this program to virgin Ubuntu 7.04 system and try to run it. It doesn't run, as expected. Then I add to the program directory the following files: libstdc++.so.6.0.13 libstdc++.so.6 (links to libstdc++.so.6.0.13) and execute command: LD_LIBRARY_PATH=. ./myprogram Now everything is OK. The question: how can I write installation script for such program? myprogram file itself should be placed to /usr/local/bin. What can I do with dependencies? For example, on destination computer, /usr/lib64/libstdc++.so.6 link points to /usr/lib64/libstdc++.so.6.0.8. What can I do with this? Note: the program is closed-source, I cannot provide source code and makefile.

  • Code Golf: Duplicate Character Removal in String

    - by Alex
    The challenge: The shortest code, by character count, that detects and removes duplicate characters in a String. Removal includes ALL instances of the duplicated character (so if you find 3 n's, all three have to go), and original character order needs to be preserved. Example Input 1: nbHHkRvrXbvkn Example Output 1: RrX Example Input 2: nbHHkRbvnrXbvkn Example Output 2: RrX (the second example removes letters that occur three times; some solutions have failed to account for this) (This is based on my other question where I needed the fastest way to do this in C#, but I think it makes good Code Golf across languages.)

  • Ensuring Updated CSS/JavaScript on Client Side

    - by Alex
    I'm trying to ensure that visitors of my ASP.NET MVC website always have the most-current CSS and Javascript (and not some older cached version). I tried to realize this by generating a seed value when the application domain starts, and automatically append it to the CSS and Javascript URLs (so now instead of /Content/All.js the link is /Content/All.js?549238 etc.). Unfortunately I just found out by debugging via Firebug that this causes now a full download request every time (the new "seeded" response is no longer cached at all, but I only wanted the first check to download the 'updated' version, but then cache again/only check if there is a difference). How can I achieve my goal, is there a better way of doing this? I need the client to always request the newest version, but then cache if no change happened. Edit: This appears to be related to the fact that my page is served over SSL. I asked a follow up question here regarding enabling clientside caching with SSL.

  • Image gallery with a Lightbox in jQuery

    - by Alex
    Hi. I'd like to create a jQuery image gallery of showcased products. It will show one product image at a time, with Next/Previous arrows, and a brief name and price as overlay on the image. If users click it, it will go to the order page. It will have an icon to show a larger, modal version (Lightbox style) of the image with full description, price, and a link to a page to order it. In other words, it's an inline gallery, about 250px X 150px, with next/previous option, but also with a little icon to fire it up in a lightbox type modal window that can have links. Here's an example which doesn't have the inline gallery effect. Here's another, also missing the inline gallery. Is there such a beast as what I'm looking for? Thanks.

  • How do I make PyScript work? Says it cant find python26.dll

    - by Alex
    I installed PyScript to try it out but it just wont start. It only gives me the error: "Error126: Could not open Dll "python26.dll" followed by: "Python could not be properly initialized. We must quit." I think this may have something to do with the PYTHONPATH but since I'm a newbie and dont know what it is or exactly what to put in the PYTHONPATH, after some googling, I ask here. Also, when I tried to install wxPython it was impossible becouse the PYTHONPATH could not be found. I have installed ActivePython 2.6 and the PATH is set so I can access python in cmd.

  • makefile from Linux doesn't work in OpenSolaris

    - by Alex Farber
    In OpenSolaris OS, when I run makefile generated by Eclipse CDT on the Linux OS, I get an error on the first -include line. The same error was in FreeBSD, and was solved by executing gmake instead of make. In OpenSolaris (just installed) gmake doesn't work (command not found). What package should I install and how exactly, to build Linux-generated C++ project in OpenSolaris?

  • Errors/Warnings/Debug Info no longer appears in Debug Console

    - by Alex L
    Hi Guys: This one is driving me crazy. When I run my App and open the Debug Console there is nothing there! Nope, not even the output from my NSLog statements. Before I would see a bunch of debug information starting with [Session Started ...] and ending with 'Terminating in response to SpringBoard's termination'. The Status Bar at the bottom of the Console says my App was successfully launched. Even Errors and Warnings from my code no longer appear. How do I get this to show up again? Any help would be greatly appreciated.

  • How to backup data stored with Core Data - iPhone app?

    - by Alex
    I'm using sqlite for the persistent store, so could I just upload the .sqlite file to, for example, Amazon S3 as a way of providing users with the ability to backup their app data? Then for restoring just download it back and replace the existing .sqlite file in the app's folder. Does anybody see any issues with that? Has anyone done it? Any other suggestions on how to implement data backup feature?

  • LinkButton child controls render

    - by Alex
    Hi. I want to have a LinkButton that adds 'span' tag around the text. protected override void Render(HtmlTextWriter writer) { Text = String.Concat("<span>", Text, "</span>"); base.Render(writer); } It's works perfectly, but only if I add text like this: <cc:TestLinkButton ID="TestLinkButton" runat="server" Text="SomeText"> </cc:TestLinkButton> If I want to add some image I will write something like this: <cc:TestLinkButton ID="LinkButton1" runat="server"> <asp:Image ID="Image1" runat="server" ImageUrl="~/Images/icon_holiday.png" BorderWidth="0" /> SomeText </cc:TestLinkButton> In this case Text property will be empty, because actualy "SomeText" is child control property. So question is is how to add tag around child controls.

  • Can I get a "base URL" in Wordpress within a template file?

    - by alex
    Usually in my PHP apps I have a base URL setup so I can do things like this <a href="<?php echo BASE_URL; ?>tom/jones">Tom</a> Then I can move my site from development to production and swap it easily and have the change go site wide (and it seems more reliable than <base href="" />. I'm doing up a Wordpress theme, and I am wondering, does WordPress have anything like this built in, or do I need to redefine my own? I can see ABSPATH, but that is the absolute file path in the file system, not something from the document root.

  • Making Swedish characters show properly in Windows Command Prompt using Python in Notepad++

    - by Alex
    The title explains it well. I have set up Notepad++ to open the Python script in the command prompt when I press F8 but all Swedish characters looks messed up when opening in CMD but perfectly fine in e.g IDLE. This simple example code: #!/usr/bin/env python #-*- coding: UTF-8 -*- print "åäö" Looks like this. As you can see the output of the batch file I use to open Python in cmd below shows the characters correctly but not the Python script above it. How do I fix this? I open the file in cmd using this method

  • ASP.NET MVC Route based on Web Browser/Device (e.g. iPhone)

    - by Alex
    Is it possible, from within ASP.NET MVC, to route to different controllers or actions based on the accessing device/browser? I'm thinking of setting up alternative actions and views for some parts of my website in case it is accessed from the iPhone, to optimize display and functionality of it. I don't want to create a completely separate project for the iPhone though as the majority of the site is fine on any device. Any idea on how to do this?
