  • Connecting GPS coordinates taken from a database in Android using Overlay

    - by LordSnoutimus
    I am currently building an application that allows users to track where their phone has been on a Google Map. At the moment, when the onLocationChanged() method is called, the application stores the current GPS longitude and latitude in a database and calls the animateTo() method to the current position. Using SDK 1.5, how would I go about connecting these points with a coloured line drawn on the MapView using an Overlay?.

  • Loading from pickled data causes database error with new saves

    - by hibbie
    In order to save time moving data I pickled some models and dumped them to file. I then reloaded them into another database using the same exact model. The save worked fine and the objects kept their old id which is what I wanted. However, when saving new objects I run into nextval errors. Not being very adept with postgres, I'm not sure how to fix this so I can keep old records with their existing ID while being able to continue adding new data. Thanks, Thomas

  • Get ahold of session in command object in Grails

    - by UltraVi01
    How can I get the session from within a command object? I have tried: import org.springframework.security.context.SecurityContextHolder as SCH class MyCommand { def session = RCH.currentRequestAttributes().getSession() } This throws java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.

  • Passing DataSource object from a servlet to a JavaBean

    - by Slavko
    I like the ease of using @Resource annotation to get a DataSource, but as far as I know, it's not possible to use it in a regular JavaBean. Would it be considered a bad practice if I pass the DataSource object from a servlet to a bean along with the other data to avoid having that lookup code in the bean?

    - by oman9589
    So I've been reading through the book PHP Solutions, Dynamic Web Design Made Easy by David Powers. I read through the short section on Object Oriented PHP, and I am having a hard time grasping the idea of the - operator. Can anyone try to give me a solid explanation on the - operator in OOP PHP? Example: $westcost = new DateTimeZone('America/Los_Angeles'); $now->setTimezone($westcoast); Also,a more general example: $someObject->propertyName Thanks

  • Modifying the Codec List Object in an ASF file

    - by scompt.com
    Is it possible to modify the Codec List Object in an ASF file? In particular, I would like to edit the codec name and description. I realize that this won't actually change the content of the video, but it's necessary for the video to be verified by an external tool. Does anyone know of a tool that will allow me to do this? If not, does anyone have any suggestions about how I might go about doing it using the Windows Media Format 11 SDK?

  • LinkedList insert tied to inserted object

    - by wrongusername
    I have code that looks like this: public class Polynomial { List<Term> term = new LinkedList<Term>(); and it seems that whenever I do something like term.add(anotherTerm), with anotherTerm being... another Term object, it seems anotherTerm is referencing the same thing as what I've just inserted into term so that whenever I try to change anotherTerm, term.get(2) (let's say) get's changed too. How can I prevent this from happening?

    So I'm using the datepicker plugin to make an availability calendar. Here is my javascript: http://pastebin.com/H7D9PcAg When dpSetSelected() is called it is also calling dateSelected() which triggers the AJAX call to my PHP script. I need a way to only update the database if the date is clicked on and not pre-loaded. When I pre-load the dates they are sent to the PHP page and subsequently removed.

  • What is the role of the Router Object in MVC based frameworks

    - by Saif Bechan
    In most MVC based framework I see a router object. If I look at it splits up the uri and decides what controller should be used, and which action should be fired. Even though this makes a lot of sense, I can not give this a place in the MVC patern. Is splitting up the uri not the job of the controller. And then the controller should just decide which class and function to run.
