  • Making a Web Gui to design a Garden Layout

    - by paddydub
    I would like to design a web page Gui where users can design a simple interactive garden. The user would pick a template design and receive price estimates based on the design template and the dimensions entered. I'd like the user to be able to move items such as plants, stones and be able to adjust the dimensions of the grass, paving. I'm thinking i could make it using flash but I would like to know there are any other ways I could use to implement this?

  • Will thread.join() block other clients also?

    - by maxp
    In an asp.net web application, say everytime the user makes the request, and the page loads, a thread is fired off that uses thread.join() to block execution until it's finished. Say this thread takes 10 seconds to complete. Does this mean that if 5 totally seperate users make a request to this page, mere miliseconds after the last, does this mean the last user is going to wait 50 seconds to finish their request? Or is each client request threaded?

  • lua table C api

    - by anon
    I know of: http://lua-users.org/wiki/SimpleLuaApiExample It shows me how to build up a table (key, value) pair entry by entry. Suppose instead, I want to build a gigantic table (say something a 1000 entry table, where both key & value are strings), is there a fast way to do this in lua (rather than 4 func calls per entry: push key value rawset Thanks!

  • Why do calls to waveOutGetPosition hang?

    - by MusiGenesis
    I'm using the winmm.dll API method waveOutGetPosition to get the current position of the playback of a WAV file. Sometimes this works as expected for me, but eventually one of the calls never returns and my application locks up. I found this thread with a few users who have experienced the same problem: http://social.msdn.microsoft.com/Forums/en-US/windowsgeneraldevelopmentissues/thread/c6a1e80e-4a18-47e7-af11-56a89f638ad7 but no solution. Has anyone run into this problem before?

  • Windows 7 - pydoc from cmd

    - by Random_Person
    Okay, I'm having one of those moments that makes me question my ability to use a computer. This is not the sort of question I imagined asking as my first SO post, but here goes. Started on Zed's new "Learn Python the Hard Way" since I've been looking to get back into programming after a 10 year hiatus and python was always what I wanted. This book has really spoken to me. That being said, I'm having a serious issue with pydoc from the command. I've got all the directories in c:/python26 in my system path and I can execute pydoc from the command line just fine regardless of pwd - but it accepts no arguments. Doesn't matter what I type, I just get the standard pydoc output telling me the acceptable arguments. Any ideas? For what it's worth, I installed ActivePython as per Zed's suggestion. C:\Users\Chevee>pydoc file pydoc - the Python documentation tool pydoc.py <name> ... Show text documentation on something. <name> may be the name of a Python keyword, topic, function, module, or package, or a dotted reference to a class or function within a module or module in a package. If <name> contains a '\', it is used as the path to a Python source file to document. If name is 'keywords', 'topics', or 'modules', a listing of these things is displayed. pydoc.py -k <keyword> Search for a keyword in the synopsis lines of all available modules. pydoc.py -p <port> Start an HTTP server on the given port on the local machine. pydoc.py -g Pop up a graphical interface for finding and serving documentation. pydoc.py -w <name> ... Write out the HTML documentation for a module to a file in the current directory. If <name> contains a '\', it is treated as a filename; if it names a directory, documentation is written for all the contents. C:\Users\Chevee> EDIT: New information, pydoc works just fine in PowerShell. As a linux user, I have no idea why I'm trying to use cmd anyways--but I'd still love to figure out what's up with pydoc and cmd. EDIT 2: More new information. In cmd... c:\>python c:/python26/lib/pydoc.py file ...works just fine. Everything works just fine with just pydoc in PowerShell without me worrying about pwd, or extensions or paths.

  • warning: Insecure world writable dir when I run a ruby or gem command

    Not sure why I'm getting this, but I just installed RVM, the new Ruby 1.9, and reinstalled a bunch of gems, and I get this /Users/johnsmith/.rvm/rubies/ruby-1.9.1-p378/bin/gem:4: warning: Insecure world writable dir /opt/local/bin in PATH, mode 040777 Everything still runs otherwise, but I was wondering if there was a way I could get rid of it.

  • My first c# app and first null object exception

  • MySQL Select names with last names starting with certain letter

    - by Brian
    I have a MySQL database with a field Name which contains full names. To select all people with last names starting with a particular letter, let's say A for this example, I use the following query: SELECT * FROM db WHERE Name LIKE '% A%'. However, this also selects users who have a middle name starting with A. Is there anyway to alter this query so that only a last name starting in A will be selected?

  • Best way to enter numeric values with decimal points?

    - by Andrew Grant
    In my app users need to be able to enter numeric values with decimal places. The iPhone doesn't provides a keyboard that's specific for this purpose - only a number pad and a keyboard with numbers and symbols. Is there an easy way to use the latter and prevent any non-numeric input from being entered without having to regex the final result? Thanks!

  • Multiuser XML document "database" for asp.net app

    - by Pierreten
    I was thinking about a way to allow multiple users to get CRUD access to an XML document in an asp.net app. The operations would obviously have to be made under the assumption of a multithreaded environment. For perf reasons, would it make sense to cache the document, and use a mutex on that cached version? When would changes be flushed to the physical XML document? Any and all recommendations are appreciated (also "use a database" isn't an option at this point unfortunately)

  • What happened to programming-books.com?

    - by Kurtosis
    A couple years ago I found a great site called something like 'programming-books.com' (but not exactly that). It let users submit links to their favorite books for various programming languages, and write a short blurb about why they're so good. You could include their Amazon page and the website would grab a cover picture. I've since lost that bookmark and am trying to find it again, anyone know what site I'm talking about? Is it still around? (cross-posted @ hacker news)

  • Ruby on Rails check box not updating on form submission

    - by user284194
    I have an entries controller that allows users to add contact information the website. The user-submitted information isn't visible to users until the administrator checks a check box and submits the form. So basically my problem is that if I check the check box as an administrator while initially creating an entry (entries#new) the entry will be publicly visible as expected, but if a non-admin user creates an entry (the normal user view doesn't include the 'live' check box, only the admin one does) then that entry is stuck in limbo because the entries#edit view for some reason doesn't update the boolean check box value when logged in as an admin. entries#new view: <% form_for(@entry) do |f| %> <%= f.error_messages %> Name<br /> <%= f.text_field :name %> Mailing Address<br /> <%= f.text_field :address %> #... <%- if current_user -%> <%= f.label :live %><br /> <%= f.check_box :live %> <%- end -%> <%= f.submit 'Create' %> <% end %> entries#edit (only accessible by admin) view: <% form_for(@entry) do |f| %> <%= f.error_messages %> <%= f.label :name %><br /> <%= f.text_field :name %> Mailing Address<br /> <%= f.text_field :address %> <%= f.label :live %><br /> <%= f.check_box :live %> <%= f.submit 'Update' %> <% end %> Any ideas as to why an administrator can't update the :live check box from the edit view? I would greatly appreciate any suggestions. I'm new to rails. I can post more code if it's needed. Thanks for reading my question.
