  • MySQL Can Connect Remotely but not Locally

    - by A Wizard Did It
    This is a weird problem and I'm not sure what's going on. I installed MySQL on a linux box I have running Ubuntu 10.04 LTS. I can access mysql via SSH mysql -p and perform all my commands that way. I added a user, and I can use AddedUser to connect remotely from my machine, but not from the local machine. It makes no sense to me... SELECT host, user FROM mysql.user Yields: +-----------+------------------+ | host | user | +-----------+------------------+ | % | AddedUser | | 127.0.0.1 | root | | li241-255 | root | | localhost | debian-sys-maint | | localhost | root | +-----------+------------------+ Problem is I'm developing on this machine using Node.js, and I can't connect locally from the server using the same username. I've tried FLUSH PRIVILEGES but that seems to have no effect. I know it's not Node.js because I'm using the same code on another database and it's working in that environment. Edit This is the error node is giving me. node.js:50 throw e; // process.nextTick error, or 'error' event on first tick ^ Error: ECONNREFUSED, Connection refused at Stream._onConnect (net.js:687:18) at IOWatcher.onWritable [as callback] (net.js:284:12) Edit 2 I have the right port & server as best I can tell.

  • JQuery: how to use "delegate" instead of "live"?

    - by JacobD
    I've read countless articles how using the JQuery delegate is much more efficient than using the "live" event. As such, I'm having trouble converting my existing Live code to using Delegate. $("#tabs li:eq(0)").live('click',function(){ //...code }); $('#A > div.listing, #B > div.listing, #C > div.listing').live('mouseover',function(){ // ...code }); When I replace the previous code with what I assume is more efficient delegate code, my page doesn't load. $("#tabs li:eq(0)").delegate('click',function(){ //...code }); $('#A > div.listing, #B > div.listing, #C > div.listing').delegate('mouseover',function(){ // ...code }); Any idea why my delegate code doesn't work? Also, any suggestions on how to make this more efficient? UPDATE: The think part of the problem is that, both "#tabs" and "#A, #B, #C" are't present on the web page at page load. Those attributes are dynamically inserted onto the page with an AJAX call. As such, does that mean I have to use live over delegate?

  • Radio Button selection Changes Toast on Android

    - by Bub
    I was writing a simple test application. There are two radio buttons within the app. There id's are "radio_red" and "radio_blue". I wanted to create an onClickListener event that read the text associated to the button and then returned a basic "Right" or "Wrong" toast. Here is a sample of the code: private OnClickListener radio_listener = new OnClickListener() { public void onClick(View v){ RadioButton rb = (RadioButton) v; String ans = rb.getText().toString(); String an1 = ""; if (ans.trim() == "Yes") { ans = "That's Right."; } else if (ans.trim() == "No") { ans = "thats wrong."; } else { ans = "none."; } Toast.makeText(v.getContext(), ans , Toast.LENGTH_SHORT).show(); } So far no joy. Here is my code snippet. I've checked my "main.xml" and the text associated to the buttons are referneced correctly. I added trim to make sure of that. However, all that is ever returned in the toast is "none." What am I missing? Thanks in advance for any help.

  • addEventListener pass caller as argument

    - by Ryan
    Hi, I have the following code. And my problem is that when clicking, the event is firing but the argument passed is not the correct one. It is passing the last dynamically created row i.e. dataStructure.length value. Anyone knows a solution how to get around this? var table = document.getElementById('output'); for(i =0; i<dataStructure.length; i++){ var row = document.createElement('tr'); row.setAttribute('id', i); var url = dataStructure[i].url; if(document.addEventListener) row.addEventListener('click', function(){handleRowClick(i);}, false); var obj = dataStructure[i]; var cellCount = 0; for(field in obj){ var cell = document.createElement('td'); cell.setAttribute('id', cellCount++); //cell.addEventListener('click', function(){window.open(dataStructureObj.links[i].url);}, false); cell.innerHTML = obj[field]; row.appendChild(cell); } cellCount = 0; table.appendChild(row); } } function handleRowClick(rowClicked){ var rowHTML = rowClicked.innerHTML; var cells = rowHTML.getElementsByTagName('td'); for(cell in cells) { alert(cell.value); } window.open(cells[1].innerHTML); }

  • javascript :Object doesn't support this property or method

    - by Kaushik
    In my jsp page, I have in the tag, the following code: <script type="text/javascript" src="<%=request.getContextPath()%>/static/js/common/common.js"></script> <script type="text/javascript"> // Function for Suppressing the JS Error function silentErrorHandler() {return true;} window.onerror=silentErrorHandler; </script> If there is some javascript executing on the jsp page after this, then I guess silentErrorHandler() will have no effect. i.e. the error will still show on page. IS this correct? Because the error is showing and am not sure why. The second part of the question is this: The error is Webpage error details User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; InfoPath.2; AskTbFXTV5/5.9.1.14019) Timestamp: Fri, 7 Jan 2011 21:26:23 UTC Message: Object doesn't support this property or method Line: 613 Char: 1 Code: 0 URI: http://localhost:9080/Claris/static/js/common/common.js And finally, line 613 states document.captureEvents(Event.MOUSEUP); There is error on IE8.

  • Make a form not focusable in C#

    - by Jandex
    Hi! I'm wanting to write a virtual keyboard, like windows onscreen keyboard for touchscreen pcs. But I'm having problem with my virtual keyboard stealing the focus from the application being used. The windows onscreen keyboard mantains the focus on the current application even when the user clicks on it. Is there a way to do the same with windows forms in C#? The only thing I can do for now is to send a keyboard event to an especific application, like notepad in the following code. If I could make the form not focusable, I could get the current focused window with GetForegroundWindow. [DllImport("USER32.DLL", CharSet = CharSet.Unicode)] public static extern IntPtr FindWindow(string lpClassName,string lpWindowName); [DllImport("USER32.DLL")] public static extern bool SetForegroundWindow(IntPtr hWnd); private void button1_Click(object sender, EventArgs e) { IntPtr calculatorHandle = FindWindow("notepad", null); SetForegroundWindow(calculatorHandle); SendKeys.SendWait("111"); } Is there a way this can be done? Any suggestions of a better way to have the form sending keyboard events to the application being used? Thanks!!

  • How to disable form submit if the username is not available

    - by Rajasekar
    I have checked the user name availability. The problem is, even if the username is not available, the form is posting. Edited Code: <SCRIPT type="text/javascript"> $(document).ready(function(){ $("#emailch").change(function() { var usr = $("#emailch").val(); if(usr.length >= 3) { $("#status").html('<img src="images/loader.gif" align="absmiddle">&nbsp;Checking availability...'); $.ajax({ type: "POST", url: "includes/check.php", data: "username="+ usr, success: function(msg){ $("#status").ajaxComplete(function(event, request, settings){ if(msg == 'OK') { $("#username").removeClass('object_error'); // if necessary $("#username").addClass("object_ok"); $(this).html('&nbsp;<img src="images/tick.gif" align="absmiddle">'); } else { $("#username").removeClass('object_ok'); // if necessary $("#username").addClass("object_error"); $(this).html(msg); } }); } }); } else { $("#status").html('<font color="red">The username should have at least <strong>3</strong> characters.</font>'); $("#username").removeClass('object_ok'); // if necessary $("#username").addClass("object_error"); } }); }); </SCRIPT> What I want is that, the form should not be posted if the user name is not available. I have tried by using return false; in IF CONDITION but it fails. Please suggest any alternate method. Any help will be appreciated.

  • How to start animation when I'm pressing on item of ListView?

    - by Ares
    I want to implement next functional: When I'm tapping on ListView's item, it's turning into red color. If I release it has to reverse color back. I made transition drawable and set it as item's background. I tried to implement SimpleGestureListener and started animation on onDown and reversed it on onSingleTapUp events, but it doesn't give me any results (works fine, but items don't turn into red). If I return super.onDown (not true), the onLongPress raise every time(even I manage to release it). @Override public boolean onDown(MotionEvent e) { if(_currentRow.getTag()!=null) if(_currentRow.getTag().toString().equals("anim")) _currentRow.setBackgroundDrawable(context.getResources() .getDrawable(R.xml.listviewitem_yellow_red)); _drawable = (TransitionDrawable) _currentRow.getBackground(); _drawable.startTransition(500); return true; //super.onDown(e); // IF I UNCOMMENT IT TURNS INTO RED, BUT TRIGGERED onLongClick event!!! } @Override public boolean onSingleTapUp(MotionEvent e) { if(_drawable!=null){ _drawable.reverseTransition(500); } return super.onSingleTapUp(e); } @Override public void onLongPress(MotionEvent e) { if(getLongClickListener()!=null) getLongClickListener().onLongClick(_currentRow, _object); super.onLongPress(e); } If someone knows how to solve this problem, please help me.

  • JavaScript: How is "function x() {}" different from "x = function() {}" ?

    - by jleedev
    In the answers to this question, we read that function f() {} defines the name locally, while [var] f = function() {} defines it globally. That makes perfect sense to me, but there's some strange behavior that's different between the two declarations. I made an HTML page with the script onload = function() { alert("hello"); } and it worked as expected. When I changed it to function onload() { alert("hello"); } nothing happened. (Firefox still fired the event, but WebKit, Opera, and Internet Explorer didn't, although frankly I've no idea which is correct.) In both cases (in all browsers), I could verify that both window.onload and onload were set to the function. In both cases, the global object this is set to the window, and I no matter how I write the declaration, the window object is receiving the property just fine. What's going on here? Why does one declaration work differently from the other? Is this a quirk of the JavaScript language, the DOM, or the interaction between the two?

  • how to use a PHP Constant that gets pulled from a database

    - by Ronedog
    Can you read out the name of a PHP constant from a database and use it inside of a php variable, to display the value of the constant for use in a menu? For example here's what I'm trying to accomplish In SQL: select menu_name AS php_CONSTANT where menu_id=1 the value returned would be L_HOME which is the name of a CONSTANT in a php config page. The php config page looks like this define('L_HOME','Home'); and gets loaded before the database call. The php usage would be $db_returned_constant which has a value of L_HOME that came from the db call, then I would place this into a string such as $string = '<ul><li>' . $db_returned_constant . '</li></ul>' and thus return a string that looks like $string = '<ul><li><a href="#" onclick="path_from_db">Home</a></li></ul>'. To sum up what I'm trying to do Load a config file based on the language preference query the db to return the menu name, which is the name of a CONSTANT in the config file loaded in step one, and also retrieve the menu_link which is used in the "onclick" event. Use a php variable to hold the name of the CONSTANT Place the variable into a string that gets echo'd out to create the menu displaying the value of the CONSTANT. I hope this makes enough sense...is it even possible to use a constant like this? Thanks.

  • Getting an updated location in Android

    - by jul
    Hi, I'm using the code shown below to get an updated value for location every time a button is clicked. When my activity is resumed I get an update every second, so that when I call getLastKnownLocation I expect to have a location that have been updated in the last second. Is that the correct way to do that? I would expect the onLocationChanged event to be triggered every time I execute a 'geo fix' command (or max after 1s since I request update every 1s), but it's only triggered the first time. Why? Any help/suggestion welcome! Thanks package org.digitalfarm.atable; ... public class Atable extends Activity { private Button mSearchButton; private TextView mytext; private LocationManager locationManager; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); mSearchButton = (Button)this.findViewById(R.id.button); mytext = (TextView) findViewById(R.id.dude); locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE); final Criteria criteria = new Criteria(); criteria.setAccuracy(Criteria.ACCURACY_FINE); mSearchButton.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { String provider = locationManager.getBestProvider(criteria, true); Location location = locationManager.getLastKnownLocation(provider); } }); } //Start a location listener LocationListener onLocationChange=new LocationListener() { public void onLocationChanged(Location loc) { //sets and displays the lat/long when a location is provided String latlong = "Lat: " + loc.getLatitude() + " Long: " + loc.getLongitude(); mytext.setText(latlong); } public void onProviderDisabled(String provider) { // required for interface, not used } public void onProviderEnabled(String provider) { // required for interface, not used } public void onStatusChanged(String provider, int status, Bundle extras) { // required for interface, not used } }; //pauses listener while app is inactive @Override public void onPause() { super.onPause(); locationManager.removeUpdates(onLocationChange); } //reactivates listener when app is resumed @Override public void onResume() { super.onResume(); locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,1000,100.0f,onLocationChange); } }

  • How to embed a precharged collection of non-entity forms in symfony2

    - by metalvarez
    I want to embed a collection of precharged non-entity forms, here is the code, first is the parent form buildForm method. public function buildForm(FormBuilderInterface $builder, array $options) { $builder->add("example1")->add("example2"); $builder->addEventListener(FormEvents::PRE_SET_DATA, function (FormEvent $event) { /*some logic to do before adding the collection of forms*/ $form->add('aclAccess', 'collection', array( 'type' => new ChildFormType(), 'allow_add' => true, 'mapped' => false, 'data' => /* I dont know how to precharge a collection of non-entity forms*/ )); }); } now the child form public function buildForm (FormBuilderInterface $builder, array $options) { $builder->add("test1", "text", array("read_only" => true, "data" => "test")); $builder->->add("test2", "choice", array( 'choices' => array('opt1' => 'Opt1', 'opt2' => 'Opt2'), 'multiple' => true, 'expanded' => true )); } so basicly i want to manage those child options in the test2 field as separated forms, each option group will depend on the value of the test1 field, i know this can be done by coding everythin in twig without form classes but i think having form classes its the best practice to run phpunit test, for maintainability, etc ...

  • C# Step by Step Execution

    - by Sheldon
    Hi. I'm building an app that uses and scanner API and a image to other format converter. I have a method (actually a click event) that do this: private void ButtonScan&Parse_Click(object sender, EventArgs e) { short scan_result = scanner_api.Scan(); if (scan_result == 1) parse_api.Parse(); // This will check for a saved image the scanner_api stores on disk, and then convert it. } The problem is that the if condition (scan_result == 1) is evaluated inmediatly, so it just don't work. How can I force the CLR to wait until the API return the convenient result. NOTE Just by doing something like: private void ButtonScan&Parse_Click(object sender, EventArgs e) { short scan_result = scanner_api.Scan(); MessageBox.Show("Result = " + scan_result); if (scan_result == 1) parse_api.Parse(); // This will check for a saved image the scanner_api stores on disk, and then convert it. } It works and display the results. Is there a way to do this, how? Thank you very much!

  • Aligning messageformat on printing a JTable.

    - by DanielFH
    I'm using this for the moment to print out my table, and it works. But I'm not really happy with the layout of the messageformatting, I would like to have both pagenumber and date in the footer, and date format aligned to the left side of the table, and page to the right. How can I do that? Been reading some stuff about overriding the PrintTable method, but seems to get pretty complex from what I've read. Hope you can help me with this issue, thank you. :) import javax.print.attribute.HashPrintRequestAttributeSet; import javax.print.attribute.PrintRequestAttributeSet; import javax.print.attribute.standard.OrientationRequested; import javax.swing.JTable; import dk.beesys.rims.ui.WindowInventory; public class Print { private static Print INSTANCE; public static Print getInstance() { if (INSTANCE == null) { INSTANCE = new Print(); } return INSTANCE; } private Print(){ } public void printList(java.awt.event.ActionEvent ignore) { String strDate = MessageFormat.format("{0,date,short} {0,time,short}", new Date()); MessageFormat header = new MessageFormat("- {0} -"); MessageFormat footer = new MessageFormat("Printed: " + strDate); PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet(); aset.add(OrientationRequested.LANDSCAPE); try { WindowInventory.getInstance().getTable().print(JTable.PrintMode.FIT_WIDTH, header, footer, true, aset, true); } catch (java.awt.print.PrinterException e) { System.err.format("Cannot print %s%n", e.getMessage()); } }

  • Dynamic GUI Framework Designing

    - by user575715
    There is a Scenario to be developed for a 3-tier Application .We need to design a Framework or a utility sort of thing . In tradional aspect of GUI Designing , either we tend to create a static gui page and code the elements on it along with other properties of the elements such as (disabled/enabled,image source,name ,id ,which function to be called under onclick event.) or we tend to drag and drop the elements from the control pallete provided by variety of gui frameworks. Certain things i need to design a POC so that we can develop this concept. 1) There must a utility ,such that during creation of screen layout , that screen should be saved in the database(RDBMS) with a screen number. 2) All the Events related to that control should be saved in some other table which will be dynamically mapped during the calling of screen number by the user. 3) When the user call that screen ,a generic function should be invoked which'll call the screen file from the database and apply all the properties ,events,etc at runtime and the final output will be displayed to the user. This POC will help the us to customised the screens according to our usage.also all the code will seperated which can easily be used for some other development process. Thanks Amit Kalra

  • How do you lock down & secure files stored on server in ASP.NET?

    - by Jon
    How do I go about securing files that are stored on the server? We have an ASP.NET app which generates PDFs. These are not stored in the wwwroot folder but in another folder i.e. C:\inetpub\data. This provides more security but maybe not enough. The ASP.NET/IIS process will need write access to this folder so it generate the PDFs there. Once the pdf is generated, it can be viewed using an ASP.NET form called viewpdf.aspx with the file to be viewed add to the query string like so viewpdf.aspx?FILE=mynewfile.pdf. This is loaded from a gridview. The full path to C:\inetpub\data is resolved and loaded in the Page_load event of the viewer page. Now I'm wondering how to secure this. Anybody could just view the file. Not by entering in the URL, as it won't been seen by IIS (its not in wwwroot), but could change the querystring in the viewpdf page. How do I stop anybody hacking this?

  • Modify onclick function with jQuery

    - by Chris Barr
    I've got a button that has an onclick event in it, which was set on the back end from .NET. Beside it is a checkbox <button class="img_button" onclick="if(buttonLoader(this)){WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions('uxBtnRelease', '', true, '', 'somepage.aspx?oupid=5&fp=true', false, true))} return false;" type="button">Release</button> <input type="checkbox" checked="checked" id="myCheckbox"> When the checkbox is clicked, needs to change the value of the query string in the URL inside the onclick function of the button. So far I have this, and the idea is right, but I keep getting errors when it's run: "Uncaught SyntaxError: Unexpected token ILLEGAL" var defaultReleaseOnClick=null; $("#myCheckbox").click(function(){ var $releaseBtn = $(".img_button"); if(defaultReleaseOnClick==null) defaultReleaseOnClick=$releaseBtn.attr("onclick"); var newOnClickString = defaultReleaseOnClick.toString().replace(/&fp=[a-z]+'/i,"&fp="+this.checked); $releaseBtn.removeAttr("onclick").click(eval(newOnClickString)); }); I know it seems kinda hacky to convert the function to a string, do a replacement, and then try to convert it back to a function, but I don't know any other way to do it. Any ideas? I've set up a demo here: http://jsbin.com/asiwu4/edit

  • MVC2 Json request not actually hitting the controller

    - by SlackerCoder
    I have a JSON request, but it seems that it is not hitting the controller. Here's the jQuery code: $("#ddlAdminLogsSelectLog").change(function() { globalLogSelection = $("#ddlAdminLogsSelectLog").val(); alert(globalLogSelection); $.getJSON("/Administrative/AdminLogsChangeLogSelection", { NewSelection: globalLogSelection }, function(data) { if (data.Message == "Success") { globalCurrentPage = 1; } else if (data.Message == "Error") { //Do Something } }); }); The alert is there to show me if it actually fired the change event, which it does. Heres the method in the controller: public ActionResult AdminLogsChangeLogSelection(String NewSelection) { String sMessage = String.Empty; StringBuilder sbDataReturn = new StringBuilder(); try { if (NewSelection.Equals("Application Log")) { int i = 0; } else if (NewSelection.Equals("Email Log")) { int l = 0; } } catch (Exception e) { //Do Something sMessage = "Error"; } return Json(new { Message = sMessage, DataReturn = sbDataReturn.ToString() }, JsonRequestBehavior.AllowGet); } I have a bunch of Json requests in my application, and it seems to only happen in this area. This is a separate area (I have 6 "areas" in the app, 5 of which work fine with JSON requests). This controller is named "AdministrativeController", if that matters. Does anything jump out anyone as being incorrect or why the request would not pass to the server side?

  • when to clear or make null asp .net mvc models?

    - by SARAVAN
    HI, I am working in an asp .net mvc application. I am using the model and storing some of the values which i need to preserve between the page posts, in the form of datacontexts. Say my model looks something like this: public SelectedUser SelectedUserDetails { //get and set has //this.datacontext.data.SelectedUser = ..... //return this.datacontext.data..... } Now when this model needs to be cleared? I have many such models with many properties and datacontext. But I don't have an idea on when to clear it. Is there a way or an event that can be triggered automatically when the model is not used for a long time? Oneway I thought is when i navigate away from a page which uses my underlying model, I can clear that model if its no longer used anywhere and initialise it back as needed. But I need to clear almost many models at many points. Is there an automatic way that can clear models when it is no longer used beacuse care can be taken by my code to initialise them when I need them, but I don't know when to clear them when I no longer need them. I need this to get rid of any memory related issues. Any thoughts or comments?

  • Using awk to return only certain chunks of data

    - by Koriar
    I'm not 100% certain how to phrase my question simply, so I apologize if this has been answered somewhere and I was just unable to find it. What I have are debug logs with authentication packets in them along with a bunch of other output. I need to search through about 2 million lines of logs to find every packet that contains a certain mac address. The packets look something like this (slightly censored): -----------------[ header ]----------------- Event: Authd-Response (1900) Sequence: -54 Timestamp: 1969-12-31 19:30:00 (0) ---------------[ attributes ]--------------- Auth-Result = Auth-Accept Service-Profile-SID = 53 Service-Profile-SID = 49 RADIUS-Access-Accept-Attr/WiMAX-Capability = 0x(numbers) Session-Timeout = 3600 Service-Profile-SID = 4 Service-Profile-SID = 29 Chargeable-User-Identity = "(Numbers)" User-Password = "(the MAC address I'm looking for)" -------------------------------------------- However there are about 10 different possible types with different possible lengths. They all start with the header line and end with the all-dashes line. I've had success using awk to get the code blocks themselves using this: awk '/-----------------\[ header \]-----------------/,/--------------------------------------------/' filename.txt But I was hoping to be able to use it to return only the packets which contain the MAC address that I need. I've been trying to figure this out for a few days now and I'm pretty stuck. I could try and write a bash script, but I could swear that I've used awk to do something like this before...

  • jQuery: If user clicks out of div

    - by Paul Knopf
    I am creating a popup in query. All is well with the popup on hover. I made it see a timer starts when user's mouse leaves the div to close it. If he enters the div again before the timer is done, then the timer is cleared. This is fine, but what if a user clicks out of the div? I want that to also close the div. The only problem is that I don't want to attach click events to the wrapper on the page (because it includes the popout menu). I have seen techniques that wraps entire screen with a transparent div, and then attach a click event to hit. Although this may work, it confuses the user if he clicks the hidden div intending to click a link. He will have to click the link twice. Once two close the div (hiding the link), and another time to actually click think. Also, you loose in mouse cursors attached to any masked elements on the page (such as links cursor pointer, etc). There has to be a way to check if the user clicked out of the div without a modal and without attaching events to the entire page (page wrappers and child elements included). onclicksomewhereelse="closeme();" lol.

  • Flash - can't access classes in another SWF

    - by Ashley Muller
    Hi, I'm trying to load a local SWF file and use the classes in that SWF (its a code only SWF, nothing in library). Here's the code that loads the library: var AD:ApplicationDomain = ApplicationDomain.currentDomain; var context:LoaderContext = new LoaderContext(false, AD); SA_gamecore_loader = new Loader(); SA_gamecore_loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onGameCoreLibraryDataComplete); SA_gamecore_loader.load(new URLRequest("GameCore.swf"), context); Here's the code that tries to instantiate a class from GameCore.swf: var test:Class = GetClassFromDefinition("MenuArt") as Class; var testInstance:Object = new test(); public function GetClassFromDefinition(theStr:String):Object { var theClass:Object; try { theClass = GameCoreLibraryData.applicationDomain.getDefinition(theStr); } catch(e:ReferenceError) { trace(e); return null; } return theClass; } And this is the message that's traced: ReferenceError: Error #1065: Variable MenuArt is not defined. The GameCore.swf is in the same location as the parent swf. I'm using Flash Develop if that helps. Anyone able to point out what I'm doing wrong?

  • Designing model/database for distance between any two locations (that may change)

    - by Yo Ludke
    We should create a web app which has a number of events each with a location (created as user-generated content, so the number of events will be increasingly large). The distance between any events should be available, for example to determine the top 5 closest events and such things. Users may change the locations of events. How should one design the database/model for this (in a scalable way)? I was thinking of doing it with a "distance table" (like so http://www.deutschland-tourist.info/images/entfernungstabelle.gif). Then every time, if a location changes, one row and one column have to be recalculated (this should be done with a delayed job, because it is not important to have the changes instantly). Possible problems in Scaling: Database to large (n² items for n events), too much calculation to be done. For example we should see if this is okay for 10.000 users. If each has created just one event, then this would be 100 million integers... Do you think this would be a good way to do it efficiently? How could one realize such a distance table with an rails model? Is it possible with a SQL databse? Would you start other approaches?
