  • Mysql retrieve polygon data

    - by dskanth
    Hi, i have been developing a site that stores spatial data in mysql database, like that of buildings, gardens, etc. in the form of polygons (latitudes and longitudes). I want to know how to retrieve polygon data in mysql. I have seen this sample query to insert a polygon data: http://amper.110mb.com/SPAT/mysql_initgeometry2.htm But now i want to know how to retrieve data from the table, based on certain constraints like: "where latitude < 9.33 and longitude > 22.4" Also how do i find whether a point lies inside or outside of a polygon

  • Should I use interface builder or not?

    - by Michael Waterfall
    I'd like to know more about the pros and cons of using interface builder when developing iPhone/iPad apps. I've written a fairly complex and customized app that's on the app store right now, but all of the interfaces are hand coded as they are fairly complex. I've customised the navigation and tab bars with backgrounds, table view cells are manually drawn for speed, and some views are complex and scalable with many subviews. I'm pondering whether or not to start using interface builder but I'm not sure to what extent I'll use it and whether it's worth it at all. Is it quicker? Can things still be easily customised? Any advice would be most welcome!

  • Silverlight caching HTTP POST which results in a 404

    - by Steav
    Situation: I am developing a Silverlight-Application which needs Component based on a local HTTP Listener. The HTTP-Listener can't be 'required' to be installed and running when the Application starts, so the Application does the following: Handshake via HTTP POST If Connection failed open a Click-Once Setup to install the component. So far so good.... now the Problem is: If the HTTP POST for the Handshake fails, because the Listener is not running the POST is cached.... and the following Connection Attempts after the Service is running fail, because the HTTP POST is still in Cache after the first try. NOTE: This is NOT a policy-problem. I'm using SL4 PS: I allready tried adding a random parameter to the URL like First try: Second try: didn't work :-(

  • Commercial CMS on Google App Engine, violation of terms?

    - by Yaggo
    I'm developing commercial CMS running on Google App Engine. I'm thinking of selling it in two ways: 1) Software as a service (SaS). The CMS running in my App Engine account (as single app), hosting the sites of all customers. A turn-key solution for "end user" customers. 2) Licence for running the CMS in customer's own App Engine account. Targeted for digital agencies for reselling as SaS. Being not a lawyer myself, I don't trust my abilities to read between the lines of TOS jargon. Counting on the general knowledge of SO community, my question is: do the above scenarios violate the App Engine Terms of Service?

  • Annoying Bug in banner cycle

    - by Davemof
    I have created a rotating banner script for a new site I'm developing View banner here(it rotates every 10 seconds) Unfortunately to the transition seems to be a biut buggy, and the image will fade out, show the same image again and then fade in the new one. I think I have made a simple error somewhere, but can't figure out where it is. the code used to cycle the banners is: In document ready: if ($('.home').length > 0){ $('<img width="100%" />').attr('src', '/assets/img/backgrounds/home/hero'+homecount+'.jpg').load(function(){ $('.hero').append( $(this) ); $('.hero img').fadeIn('medium').delay(10000).fadeOut('slow', loopImages); setHeroHeight(); }); } Outside document ready: function loopImages(){ homecount = homecount+1; if (homecount > 5){ homecount = 1; } $('.hero img') .attr('src', '/assets/img/backgrounds/home/hero'+homecount+'.jpg') .load(function(){ $('.hero img').fadeIn('fast')}).delay(10000).fadeOut('slow', loopImages); } Any help would be greatly appreciated Thanks Dave

  • php - what kind of download counter big websites companies have?

    - by dinbrca
    Hi, I am developing in php and trying to implement a download counter to count the times that users downloaded my application.. I also read the following topics: Best way to implement a download counter? Best way to count file downloads on a website and found nothing useful enough.. What I would like to ask is: what kind of download counter the big companies implement? is it when the user cancels the download doesn't count? Is it even possible - to count file downloads, and remove 1 from the count if the user canceled the download? I already have a script that works great - but only when the file is 1MB or upper, when its less than a 1MB and a user cancels the download - the download still counts.. Thanks in advanced, Din.

  • Approach to data wrapping

    - by Mikhail
    I'm developing in PHP and MySQL. The information about the currently logged in user is stored in many different tables. The information that I need on each page, I preload. However if something is needed from a rarely accessed table - then I do $newdata = $db->Query('SELECT * FROM rare_table WHERE user_id='.$user->id); I would like to simplify the above to a point where I don't have to specify that the query should be limited to this particular user. An ideal function call would be: $newdata = $user->Query('SELECT * FROM rare_table'); Obviously I'd have to parse the SQL and add a WHERE clause. Or add to the already existing clause. Questions: are there tools to do this? How can I develop this? Is this even a good idea?

  • Facebook Card Game? Which architecture?

    - by Ben
    I am developing a Facebook Card Game for my thesis and i am wondering which architecture fits best? I am going to develop the game using Silverlight + ASP.NET. On the one side the game should contain player vs. player card games. On the other there will be also a lot of contant similar to Mafia Wars(or any other game like that) where you just interact with the server (incl. database) I read a lot about ASP.NET MVC, Silverlight MVVM and that stuff. But what fits best for a game like that? Also i am not sure if i should go with Silverlight 4 already? I don't want to start the wrong way. I really appreciate your help.

  • Forcing a method to be non-transactional in JPA (Eclipselink)

    - by rhinds
    Hi, I am developing an application using Eclipselink and as part of the app I need to be able to manipulate some of the objects which involves changing data without it being persisted to the database (i merging/changing objects for some batch generation processes). I am reluctant to change the data in the Entity objects, as there is a risk that even though i have not marked the methods as @Transactional, this method could in the future be inadvertantly called from within a transactional method and these changes could be persisted. So my question is, is there anyway to get around this? Such as force a method to always be non-transactional regardless; terminate any transactionality as soon as the method is started; etc. I know there is a .detach() method that can detach the objects from the Entity Manager, however, there are many objects and this seems like a potentially error prone fail-safe on my code.

  • Incorporation of YUI 3 in rails

    - by lorefnon
    I was wondering if any effort has been made towards integration of YUI3 with rails asset pipeline. By integration, I don't just mean a couple of helpers for including the library but rather a complete integration of YUI module loader. I'll elaborate the idea in detail: Currently, developers developing modules using YUI rely on Ant tasks for concatenating the module components and wrapping them up with some associated metadata and generating target files ( and optionally minifying and running jslint). Also, when fetching the modules, the YUI loader calculates the module dependencies and generates a single file comprising of all the dependencies which havent been included already in the page. I was wondering if the whole functionality could be seamlessly integrated into the Asset pipeline of rails.

  • How to grab all cookies in Flash

    - by Leticia Meyer
    For a site I'm developing with a user login that uses cookies to store the session ID, a separate section of it uses Flash to provide content and such. Is there some way it can access the cookies that were set the by login? The name of the cookie will not the be same every time, as it is randomly generated, as well as its value. I then need to send the name and value of the cookie back to a page on the server to do additional stuff. Anyone know how to do this? Note that I didn't write the Flash interface, an the person who did doesn't know how to do this. Please help me, and thanks in advance!

  • Securing a REST API

    - by Christopher McCann
    I am in the middle of developing a REST API - the first one I ever have. The data being passed through the API is not of such a critical nature that there will be loss of life, economics etc if it was intercepted but at the same time I would like it to be secure. The data being transferred is simply like the data that would be transferred on Twitter or Facebook - not overly confidential but still should be kept private. What is the best way to secure this data? Am I best to use HTTP Basic Auth over SSL or should I be looking into something like OAuth. I have never really used REST much before so bit of a first for me. Thanks

  • Java Swing - Problem in JSpinner

    - by Yatendra Goel
    I am developing a Java Desktop Application and designing the GUI with the help of Netbeans Swing GUI builder. I want to use a JSpinner in my app. I have dragged and dropped it to a JPanel. Now, I want to set its two properties: First, It should display numbers in the range of 1 to 50. Neither less than 1 nor greater than 50. How can I set that range? Second, when I try to get the value of it by spinner.getValue() it returns an Object. As my spinner's data type is Integer, would it be better to downcast the Object into Integer or Is there any other way to get that numeric value?

  • Differing form size between XP and 7

    - by Andy
    I am developing a C# WinForms app on my XP dev machine with Visual C# Express 2008. I set the form to have a size of my liking with Width and Height on the designer and all looks good. I also set these dimensions to the MaximumSize property. Deploying the app to another XP machine, and the app looks like it does on my dev. However, in testing the app on a Win7 machine, the form has both horizontal and vertical scrollbars applied. I assume that this is due to the changed non-client size of the form, as determined by Win7. I can resize the window, but I would like it to be displayed correctly to begin with. So, my question is: What is the best way to correctly maintain a form size client area across OS'es? Thanks all.

  • How to make schema and code dynamic?

    - by Jonarch
    I want to make my database schema and application code as dynamic as possible to handle "unknown" use cases and changes. Developing in PHP and MySQL. Twice now I have had to change my entire schema including table and column names and this means the developers have to go back to the application code and modify all the SQL queries and table/columns names. So to prevent this I want to if just like we do on pages where we have page content, title bar etc dynamic like a %variable%, can we do it for the schema and maybe even for the php code functions and classes somehow? It takes weeks to re-do all changes like this vs if it is dynamic it can be done in under a day.

    Hi, I developing an application in which the pixelize image i want to be store in matrix format. The code is as follows. struct pixel { //unsigned char r, g, b,a; Byte r, g, b; int count; }; (NSInteger) processImage1: (UIImage*) image { // Allocate a buffer big enough to hold all the pixels struct pixel* pixels = (struct pixel*) calloc(1, image.size.width * image.size.height * sizeof(struct pixel)); if (pixels != nil) { // Create a new bitmap CGContextRef context = CGBitmapContextCreate( (void*) pixels, image.size.width, image.size.height, 8, image.size.width * 4, CGImageGetColorSpace(image.CGImage), kCGImageAlphaPremultipliedLast ); NSLog(@"1=%d, 2=%d, 3=%d", CGImageGetBitsPerComponent(image), CGImageGetBitsPerPixel(image),CGImageGetBytesPerRow(image)); if (context != NULL) { // Draw the image in the bitmap CGContextDrawImage(context, CGRectMake(0.0f, 0.0f, image.size.width, image.size.height), image.CGImage); NSUInteger numberOfPixels = image.size.width * image.size.height; I confusing about how to initialize the 2-D matrix in which the matrix store data of pixels.

  • Any reason why I shouldn't use couchdb for message passing or realtime activity streams?

    - by Up
    While using ampq or xmpp (rabbitmq or ejabbered that could have couchdb as backends) seems like a good fit to deliver real time updates about friend state in a social gaming platform where updates are small but frequent, I can't help but think why wouldn't couchdb be a good platform to deliver such updates? The main advantage I could think of is its ability to filter updates based on friends and availability of changes api, which makes developing such an application and managing it (including replication) quite easy compared to ampq or xmpp where you have to think about how to manage the pubsub nodes and who is subscribed to them at any point in time. However, I can't help but think this is too good to be true, I can't find information on what couchdb's shortcomings are. Somehow, it feels like using MySQL for message passing which is why I am hesitant to using it. Anyone have any experience in using couchdb for such applications? would you recommend another platform to use?

  • Is node.js ready for production use?

    - by Simon Wentley
    Starting a new project. It's basically a blogging/commenting system. We're considering node.js as the back end server. Is node.js ready for this sort of thing or is it too early and experimental? We need HTTPS and gzip compression - perhaps a front end nginx server could provide this? What's missing from node.js that would make developing a web app difficult? From a production ready perspective, we're wondering if it is stable enough for building a commercial app on top of. Thanks

  • An image cropper: How to prevent the default drag n' drop action?

    - by David Gore
    I am developing an image cropper and would like to ask you the following question: In order to prevent the default drag n' drop action when you press the left button on an image and keeping it pressed try to move the mouse, wouldn't it be cross-browser if to just use the picture as a background to a div box? Just like so: <div id="theDiv" style="background:url(pic.png) no-repeat;"></div> How do you think? Is it acceptable? Not too ugly? Or should be done with JS?

  • Does this game have a solution

    - by Bragboy
    Hi, I am developing a simple game using Java swing. I want to know whether this particular game has a solution in the following scenario. If I am convinced that theoretically a solution cannot be arrived at this point, I will throw a notification to the user. 3x3 4x4 The objective of this game is to fill numbers from 1 to 8 (or 1 to 15) using the one space available to push the numbers to that empty space. Every time I end up with the combination shown above. I just want to convince myself that there is no way to attain the proper solution from the above scenario. Please help.

  • has anyone tried designing a webpage for psp?

    - by lock
    erm im trying to make a personal bible for my psp (i tried googling but the only bible version i've seen on my skimming is on KJV and im trying to make mine have 3 versions namely TNIV, NLT and Amplified Bible) so my only solution was to make on for myself and my approach was to save an html file on my mem-stick and open it up through the console's browser my concerns are: 1. how does the psp browser handle css and javascript? 2. is there a doctype declaration specifically designed for the psp browser? 3. can i use any local database to store my texts for easier query or do i have no choice but rely on static text files? 4. is there anyone in SO who have experienced developing a page for this console and can he/she give me some tips and advice? thanks much in advance for your responses.. :)

  • UITextField showing trash instead of characters

    There's quite a strange thing happening to text fields in application I'm developing (see image below).  [1]: http://img7.imageshack.us/img7/1449/zrzutekranu20100506godz.png At some point in the application I'm using    - (void) viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; [[(TextFieldView*)[self view] usernameTextField] becomeFirstResponder];    } Which results in the above image. If it's called in viewDidAppear - everything is fine. The funny thing about this error is that it breaks ALL text fields throught the application. Has anyone ever encountered such an error? Might it be related to openGL use?
