  • Adding LegendItems in Flex places horizontally not vertically (as it's supposed to)

    - by David
    I'm dynamically inserting LegendItems into a Legend using the following code: signalLegend.removeAllChildren(); signalLegend.direction = "vertical"; for (var i:int = 0; i < numItems - 1; i++) { signalLegend.addChild(new LegendItem()); legendItem = signalLegend.getChildAt(i) as LegendItem; legendItem.label = "Title here"; legendItem.setStyle("fill", theColour); } While the Legend direction is set as vertical, all the items are appearing horizontally. Very annoying.

  • Using Thor for generators in a Ruby Gem

    - by David Burrows
    How do I setup a Gem to have a binary command eg. "project newProject" that uses Thor's set of generator commands to create files etc.? A good answer would describe how to layout the skeleton of a gem that that when run from the command line "project newProject" creates 1 file named "newProject.txt" in the directory it's run from. I've seen that Rails 3 is using Thor to power it's generators, seems like a really good solution and i'd like to use a similar approach in non-Rails ruby gem i'm working on. Tried looking at the Rails 3 source but it's a bit labyrinthine hence the question.

  • 301 Redirecting URLs based on GET variables in .htaccess

    - by technicalbloke
    I have a few messy old URLs like... http://www.example.com/bunch.of/unneeded/crap?opendocument&part=1 http://www.example.com/bunch.of/unneeded/crap?opendocument&part=2 ...that I want to redirect to the newer, cleaner form... http://www.example.com/page.php/welcome http://www.example.com/page.php/prices I understand I can redirect one page to another with a simple redirect i.e. Redirect 301 /bunch.of/unneeded/crap http://www.example.com/page.php But the source page doesn't change, only it's GET vars. I can't figure out how to base the redirect on the value of these GET variables. Can anybody help pls!? I'm fairly handy with the old regexes so I can have a pop at using mod-rewrite if I have to but I'm not clear on the syntax for rewriting GET vars and I'd prefer to avoid the performance hit and use the cleaner Redirect directive. Is there a way? and if not can anyone clue me in as to the right mod-rewrite syntax pls? Cheers, Roger.

  • Entity Framework use of indexes and foreign keys

    - by David
    I want to be able to search a table quite quickly using the Entity Framework, say if I have a Contacts table, a JobsToDo table and a matrix table linking the two tables e.g Contacts_JobsToDo_Mtx and I specify two foreign keys in the Contacts_JobsToDo_Mtx table, if I wanted to search this Mtx table, do I need to specify an index on the two foreign keys? Or by the fact that they are two foreign keys are they considered indexed on them anyway? Will the Entity Framework be able to search through the Mtx table quickly without having to specfiy an index on both keys? Thanks!

  • VS2010 express beta2 - no add reference dialog, no open file/project dialogs

    - by David
    Just installed VS2010 express for Windows Phone last night. Install went smoothly. It creates a project, compiles, and deploys the app to the emulator. Here's the problem: When I try to "Add Reference" through the Project menu, I do not get the Add Reference dialog box. Same thing if I right click References in the solution explorer and click Add Reference. That's not all. "File...Open" and "File...Open Project" also fail to throw up an open file dialog box. When attempting any of these actions, the IDE quickly loses and regains focus. Even pressing a keyboard shortcut (Ctrl+O) causes the IDE to quickly lose and regain focus, but no open file dialog box appears. This is what I have tried, not particularly in this order: 1. Turned off UAC 2. Monitored file and registry access using Process Monitor during a File...Open operation. File activity showed mostly "SUCCESS" with a few "FAST IO DISALLOWED" and a few "INVALID DEVICE REQUEST" results. Registry activity showed mostly "SUCCESS" with some "NAME NOT FOUND" and a few "BUFFER OVERFLOW" results. 3. Created a new, clean Windows account to run the IDE from 4. Forced a test project to add a reference to "System.Xml.Linq" by editing the ".csproj" project file. Project failed to load in the IDE. I don't have these problems at all on 2 other Windows 7 computers with VS2010 C# express beta 2 installed. One machine is 32bit and the other 64bit, both Home Premium edition. My system: Windows 7 Home Premium, 64bit Other Visual Studio products installed: VS2008 C# express, VS2008 C++ express One other thing to note: Several months ago I installed the non-phone distribution of VS2010 C# express beta 2, and I had the same exact problems. Back then I chalked it up to being beta and went back to VS2008 C# express, where I do not have these issues.

  • ASP.NET Nested masterpages, how to set content in the top page from the aspx file?

    - by David Suarez
    I have some content from a CMS that I need to move to raw asp.net pages. Since the templates are nested I guess I can use nested masterpages to acomplish it, but I'm finding that I can't set values on the top masterpage from the deep child page. Here is a sample. I have several nested masterpages with contentplaceholders: top master (with contentPlaceHolder1) nested master, dependent on top master (with contentPlaceHolder2) aspx page, dependent on nested master, defines content for contentPlaceHolder1 and 2 The problem is that asp.net doesn't allow me to have the value of contentPlaceHolder1 defined in the content page, it should be defined in the nested master. But the point is that the client page knows that value, not the template masters (for instance, the page knows about the graphic it has to display on the the top, but the placeholder for the graphic is the top master). How can I set values in the aspx page to be rendered in the top master?

  • Public Wildcard Domain Name To Resolve To 127.0.0.1

    - by Rahul
    Is anyone aware of a public wildcard domain name that resolves to IP address 127.0.0.1. For example if I wanted to test a URL locally such as mywebsite.localhost.com or example.localhost.com but I don't have control of DNS settings (hosts file or whatever) then I would use this public DNS to resolve to 127.0.0.1. It needs to be wildcarded so that no matter whatever comes before localhost.com it still resolves to 127.0.0.1.

  • Modifying my website to allow anonymous comments

    - by David
    I write the code for my own website as an educational/fun exercise. Right now part of the website is a blog (like every other site out there :-/) which supports the usual basic blog features, including commenting on posts. But I only have comments enabled for logged-in users; I want to alter the code to allow anonymous comments - that is, I want to allow people to post comments without first creating a user account on my site, although there will still be some sort of authentication involved to prevent spam. Question: what information should I save for anonymous comments? I'm thinking at least display name and email address (for displaying a Gravatar), and probably website URL because I eventually want to accept OpenID as well, but would anything else make sense? Other question: how should I modify the database to store this information? The schema I have for the comment table is currently comment_id smallint(5) // The unique comment ID post_id smallint(5) // The ID of the post the comment was made on user_id smallint(5) // The ID of the user account who made the comment comment_subject varchar(128) comment_date timestamp comment_text text Should I add additional fields for name, email address, etc. to the comment table? (seems like a bad idea) Create a new "anonymous users" table? (and if so, how to keep anonymous user ids from conflicting with regular user ids) Or create fake user accounts for anonymous users in my existing users table? Part of what's making this tricky is that if someone tries to post an anonymous comment using an email address (or OpenID) that's already associated with an account on my site, I'd like to catch that and prompt them to log in.

  • How to re-use a thread in Java ?

    - by David
    I am a building a console Sudoku Solver where the main objective is raw speed. I now have a ManagerThread that starts WorkerThreads to compute the neibhbors of each cell. So one WorkerThread is started for each cell right now. How can I re-use an existing thread that has completed its work? The Thread Pool Pattern seems to be the solution, but I don't understand what to do to prevent the thread from dying once its job has been completed. ps : I do not expect to gain much performance for this particular task, just want to experiment how multi-threading works before applying it to the more complex parts of the code.

  • How do you diagnose a 500 error on Heroku when there is no error message in the logs?

    - by lala
    I have a Rails app on Heroku that is serving 500 errors at random intervals. Web pages will display "Internal server error" in plain text, instead of the usual "We're sorry. Something went wrong." page. When I refresh the page, it works fine. The logs don't show me an error message, just » 14:20:34.107 2013-10-11 12:20:33.763690+00:00 heroku router - - at=info method=HEAD path=/ host=www.mydomain.com fwd="184.73.237.85/ec2-184-73-237-85.compute-1.amazonaws.com" dyno=web.1 connect=1ms service=63ms status=200 bytes=0 » 14:21:03.957 2013-10-11 12:21:03.561867+00:00 heroku router - - at=info method=GET path=/ host=www.mydomain.com fwd="50.112.95.211/ec2-50-112-95-211.us-west-2.compute.amazonaws.com" dyno=web.1 connect=0ms service=1ms status=500 bytes=21 Support has told me to look at request queuing in New Relic, but New Relic only shows a big red mark saying the server is down (even though the site works fine when refreshed). With no error messages, I'm at a loss for how to diagnose this issue.
