  • Easiest way to export longitude and latitude data stored in a SQLite database to a file so it can be

    - by LordSnoutimus
    Hello, I have created an application that records a series of longitude and latitude values in a SQLite database and display them as a coloured track on a MapActivity. I now want to be able to export this data somehow (preferably to a file) so a user can upload the values to a website showing a Google Map API. My question is: what would be the quickest way to export the data (and in what file format: GPX, XML, CSV) to the SD card located on the Android device. Many thanks.

  • host MVC app inside a website

    - by Nishant
    I have a website (not a web application- in visual studio you get two options-create a website/project) running on IIS 6.0. Now I want to develop few features in MVC architecture. So I created one MVC application in visual studio and everything is working fine on localhost as a separate application. Now I want to host this MVC app also inside the website I have already deployed. I created a virtual directory(MVCDir) inside the default website in IIS 6.0. The global.asax file which was in root folder I added the routing function- Shared Sub RegisterRoutes(ByVal routes As RouteCollection) routes.Ignore("{resource}.axd/{*pathInfo}") routes.Ignore("{resource}.aspx/{*pathInfo}") routes.MapPageRoute("Default4", "{controller}/{action}/{id}", "~/MVCDir", False, New RouteValueDictionary(New With {.controller = "Home", .action = "Index", .id = Mvc.UrlParameter.Optional})) End Sub * NOTE- If I write routes.ignoreRoute instead of routes,ignore it says- IgnoreRoute is not a member of System.Web.RoutingCollection* I called this routing function inside application_start function now when I run domain.com/home/index How to solve this problem? it says resource not found

  • Implementing tagging in JDO

    - by Julie Paltrow
    I am implementing a tagging system for a website that uses JDO . I would like to use this method. However I am new to relationships in JDO. To keep it simple, what I have looks like this: @PersistentCapable class Post { @Persistent String title; @Persistent String body; } @PersistentCapable class Tag { @Persistent String name; } What kind of JDO relationships do I need and how to implement them? I want to be able to list all Tags that belong to a Post, and also be able to list all Posts that have a given Tag. So in the end I would like to have something like this: Table: Post Columns: PostID, Title, Body Table: Tag Columns: TagID, name Table: PostTag Columns: PostID, TagID

  • Framework/App for custom maps(not general google maps)

    - by Franz Xaver
    Hi! I've started to develop in Android 2 weeks ago and until now, I like it! Currently I am working on a project where I have to display an individual map (not a google maps view, I'd like to display the map of a building's interior) with which the user can interact(mark positions, etc.). Is there a framework or an existing app that I could use? Of course I searched the internet but could not find anything. Perhaps it is in some way possible to use the google maps API? I hope you can help me, thanks in advance!

  • Is there a user provisioning API, and/or account migration/transition tool for Gmail on Google Apps?

    - by Olaseni
    I've decided to move all the mail accounts in my domain to Google Apps: Is there a subtle migration tool that can make the transition painless, since I want all the mail history and folders to be intact. I'm also looking to duplicate the user provisioning API with Google Apps Users alternative. Are my goals realistic? Are there any tools out there that already make this task simpler?

  • How to change order in ordered+persisted collection?

    - by Jaroslav Záruba
    I just need to change order of items in a (previously persisted) ordered collection... I tried simply passing the re-arranged collection to a setter: after committing a transaction the collection is gone. Then I tried to clear() the existing collection and addAll() afterwards: clear() makes persistent manager to mark all the elements as deleted. (But obviously I would like to be able to work with the collection items in the very transaction.) (The collection is not in a default fetch group, so I tried the above also with the named fetch group added into the fetch plan. No luck.) This must be the most stupid question, but I ran out of ideas and I'm stuck here two days already. I swear I googled. :(

  • Google Spreadsheet API problem: memory exceeded

    - by Robbert
    Hi guys, Don't know if anyone has experience with the Google Spreadsheets API or the Zend_GData classes but it's worth a go: When I try to insert a value in a 750 row spreadsheet, it takes ages and then throws an error that my memory limit (which is 128 MB!) was exceeded. I also got this when querying all records of this spreadsheet but this I can imaging because it's quite a lot of data. But why does this happen when inserting a row? That's not too complex, is it? Here's the code I used: public function insertIntoSpreadsheet($username, $password, $spreadSheetId, $data = array()) { $service = Zend_Gdata_Spreadsheets::AUTH_SERVICE_NAME; $client = Zend_Gdata_ClientLogin::getHttpClient($username, $password, $service); $client->setConfig(array( 'timeout' => 240 )); $service = new Zend_Gdata_Spreadsheets($client); if (count($data) == 0) { die("No valid data"); } try { $newEntry = $service->insertRow($data, $spreadSheetId); return true; } catch (Exception $e) { return false; } }

  • Google Datastore low-level api query by key property

    - by Keyur
    I'm using the low-level google datastore api and I want to query by the key property and another property (let's call it category). I need to query based on a list of keys for which I'll use the IN operator. I know that the max. number of values you can provide for the IN clause is 30. I have 2 questions: Does the limit of 30 IN values apply to the key property as well? Do I need to create a composite index on {_key_ + category} or just on {category} for this query? Thanks, Keyur

  • Flex / ZendAMF / PHP app, corrupted data with some linux clients problem

    - by Laurent Jégou
    Hello, i'm buiding a survey web application, using Flex for the front-end (nice forms), and a MySQL database for the storage, linked by PHP with the help of ZendAMF. I largely borrowed from this nice tutorial by Alan Gruskoff : http://digitalshowcase.biz/wordpress/?page_id=26 (The only one tutorial i've found to work with the last version of Flex). The app seems to works nicely in my tests, except on certain linux boxes : the data is somehow corrupted : there is no error message, no glitch, but the response of the forms are not what the user selected. I tried to reproduce the error on a fresh installed ubuntu VM, but it works fine. I've asked friends for some tests, and several linux users showed the same problem, on ubuntu and suse machines, all freshly updated and functionnal. The application was targeted to be the survey tool for my doctoral thesis, so i'm quite desperate here, and before i'm dumping it to start anew with php only, i'm asking here in case someone can help, thanks :-) Please excuse my english, by the way. LJ.

  • why am I stuck on "Initiating update" when deploying to google

    - by michelle
    I've have not had any trouble deploying through eclipse until now. I'm guessing it might have to do with all the stuff I've added today a folder of .pdf and .tex files (in war/web-inf directory) a bit of JDO stuff and a servlet that reads the files in the directory and indexes them into the JDO Is there any way to find out what exactly is the problem?

  • Dot Net Nuke app_offline randomly being generated

    - by chelfers
    We have had multiple DNN sites running for quite a few months now without any issues. Twice in the last 3 days our sites have gone offline by the addition of the app_offline.htm file in the root dir. There is only one developer with access to the sites at a coding / directory viewing level and the file is generated at weird times times when he is NOT accessing our network. We are not publishing anything to the server ( and have not published any .net code in days ), upgrading, changing code, or even modifying content. Has anyone run into this issue?

I know that memory management is not proper or is it because os some other reason.

  • Prevent an Activity from being killed by the OS while starting a child activity

    - by Martin Marinov
    I have a main activity which calls a child one via Intent I = new Intent(this, Child.class); startActivityForResult(I, 0); But as soon as Child becomes visible the main activity gets its onStop and immediately after that onDestroy method triggered. And as soon as I call finish() within the Child activity or press the back button, the Child activity closes and the home screen shows (instead of the main activity). How can I prevent the main activity from being destroyed? :\

  • Execute function without sending 'self' to it

    - by Sergey
    Is that possible to define a function without referencing to self this way? def myfunc(var_a,var_b) But so that it could also get sender data, like if I defined it like this: def myfunc(self, var_a,var_b) That self is always the same so it looks a little redundant here always to run a function this way: myfunc(self,'data_a','data_b'). Then I would like to get its data in the function like this sender.fields. UPDATE: Here is some code to understand better what I mean. The class below is used to show a page based on Jinja2 templates engine for users to sign up. class SignupHandler(webapp.RequestHandler): def get(self, *args, **kwargs): utils.render_template(self, 'signup.html') And this code below is a render_template that I created as wrapper to Jinja2 functions to use it more conveniently in my project: def render_template(response, template_name, vars=dict(), is_string=False): template_dirs = [os.path.join(root(), 'templates')] logging.info(template_dirs[0]) env = Environment(loader=FileSystemLoader(template_dirs)) try: template = env.get_template(template_name) except TemplateNotFound: raise TemplateNotFound(template_name) content = template.render(vars) if is_string: return content else: response.response.out.write(content) As I use this function render_template very often in my project and usually the same way, just with different template files, I wondered if there was a way to get rid of having to call it like I do it now, with self as the first argument but still having access to that object.

  • Smooth table view like on iPod.app

    - by Gilo
    Hey folks ;), Im trying to redo the table view in the ipod.app. The one with 2 labels and the cover on the left. I want the same information there. I mean the cover plus all the other MPMediaItem stuff. Everything works fine. I can build the table and get all the information from the music library I need. My only problem is that my table is far away from being smooth. It lacks. When I remove the MPMediaArtworkItem from the table its super fast. So I guess its a problem with that. Is there any way to load the MPMediaProperties more faster? Whats the fastest way? THX in advance :)

  • Is it safe to change the 'Security.salt' line to a more lengthy string {64 hex key}

    - by Gaurav Sharma
    Hi everyone, I have changed the Configure::write('Security.salt', '############'); value in the file config/core.php file to a '256-bit hex key'. Is it safe or a good practice to change these lines for every different installation of cakephp application or shall I revert back to the original ? I also changed the Configure::write('Security.cipherSeed','7927237598237592759727'); to a different one of more length. Please throw some light on this. Thanks

  • Is there some performance issue between leaving empty ListProperties or using dynamic (expando) prop

    - by indiehacker
    Is there a datastore performance difference between adding dynamic properties of the expando class when they are needed for an entity or the simpler (for me) framework of just setting up all possible properties I might need from the start even though most instances will just be left empty. In my specific case I would be having 5-8 empty ReferenceList properties as 'overhead' that will be empty when I skip using expando class.
