  • loaderInfo null inside creationComplete handler function

    - by Thiago
    Hi, I've coded this small snippet to show what I'm not understanding: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="init()"> <mx:Script> public function init():void { txtName.text = this.loaderInfo.toString(); } </mx:Script> <mx:TextInput x="50" y="10" id="txtName"/> </mx:Application> I'm getting the following error: TypeError: Error #1009: Cannot access a property or method of a null object reference. at Teste/init()[C:\Lucas\flex\AppName\src\Teste.mxml:5] at Teste/___Teste_Application1_creationComplete()[C:\User\flex\CornetaRecorder\src\Teste.mxml:2] at flash.events::EventDispatcher/dispatchEventFunction() at flash.events::EventDispatcher/dispatchEvent() at mx.core::UIComponent/dispatchEvent()[C:\autobuild\3.2.0\frameworks\projects\framework\src\mx\core\UIComponent.as:9298] at mx.core::UIComponent/set initialized()[C:\autobuild\3.2.0\frameworks\projects\framework\src\mx\core\UIComponent.as:1169] at mx.managers::LayoutManager/doPhasedInstantiation()[C:\autobuild\3.2.0\frameworks\projects\framework\src\mx\managers\LayoutManager.as:718] at Function/http://adobe.com/AS3/2006/builtin::apply() at mx.core::UIComponent/callLaterDispatcher2()[C:\autobuild\3.2.0\frameworks\projects\framework\src\mx\core\UIComponent.as:8628] at mx.core::UIComponent/callLaterDispatcher()[C:\autobuild\3.2.0\frameworks\projects\framework\src\mx\core\UIComponent.as:8568] Shouldn't I be able to read loaderInfo inside the creationComplete handler? I'm trying to pass a string from the html to my flash component, that's why I have to get loaderInfo working.

  • How to debug anomalous C memory/stack problems

    - by EBM
    Hello, Sorry I can't be specific with code, but the problems I am seeing are anomalous. Character string values seem to be getting changed depending on other, unrelated code. For example, the value of the argument that is passed around below will change merely depending on if I comment out one or two of the fprintf() calls! By the last fprintf() the value is typically completely empty (and no, I have checked to make sure I am not modifying the argument directly... all I have to do is comment out a fprintf() or add another fprintf() and the value of the string will change at certain points!): static process_args(char *arg) { /* debug */ fprintf(stderr, "Function arg is %s\n", arg); ...do a bunch of stuff including call another function that uses alloc()... /* debug */ fprintf(stderr, "Function arg is now %s\n", arg); } int main(int argc, char *argv[]) { char *my_arg; ... do a bunch of stuff ... /* just to show you it's nothing to do with the argv array */ my_string = strdup(argv[1]); /* debug */ fprintf(stderr, "Argument 1 is %s\n", my_string); process_args(my_string); } There's more code all around, so I can't ask for someone to debug my program -- what I want to know is HOW can I debug why character strings like this are getting their memory changed or overwritten based on unrelated code. Is my memory limited? My stack too small? How do I tell? What else can I do to track down the issue? My program isn't huge, it's like a thousand lines of code give or take and a couple dynamically linked external libs, but nothing out of the ordinary. HELP! TIA!

  • C# Error reading two dates from a binary file

    - by Jamie
    Hi all, When reading two dates from a binary file I'm seeing the error below: "The output char buffer is too small to contain the decoded characters, encoding 'Unicode (UTF-8)' fallback 'System.Text.DecoderReplacementFallback'. Parameter name: chars" My code is below: static DateTime[] ReadDates() { System.IO.FileStream appData = new System.IO.FileStream( appDataFile, System.IO.FileMode.Open, System.IO.FileAccess.Read); List<DateTime> result = new List<DateTime>(); using (System.IO.BinaryReader br = new System.IO.BinaryReader(appData)) { while (br.PeekChar() > 0) { result.Add(new DateTime(br.ReadInt64())); } br.Close(); } return result.ToArray(); } static void WriteDates(IEnumerable<DateTime> dates) { System.IO.FileStream appData = new System.IO.FileStream( appDataFile, System.IO.FileMode.Create, System.IO.FileAccess.Write); List<DateTime> result = new List<DateTime>(); using (System.IO.BinaryWriter bw = new System.IO.BinaryWriter(appData)) { foreach (DateTime date in dates) bw.Write(date.Ticks); bw.Close(); } } What could be the cause?

  • Get data from database without refresh whole page

    - by stefanz
    Hello everybody. My project is about a school admin I have a page called : createClass.php, where user inserts grade, profile etc. When he press "submit" page called createdClass.php is loading. Inside this page I have all code which insert data into database and also an "if" structure which says : "Class already exists" if in database is another class with same specifications. Also in second page (createdClass.php) i have a small table which shows the place of each student. First time all cells are green (this means that place is free) and if i click one of them appear a popup window which let me to add info about student from that place. If a place is busy the cell will be red (take a look here : http://screencast.com/t/NzM2YzYxNjct). The big problem is that the cell will be red only after refresh the page (the place ask for data from database). If I press refresh appears "class already exists". To test the code i added in a comment all lines which verify and add respectively classroom . I think my problem can be solved with ajax. I'm waiting for an answer. Regards Stefan

  • Using a Scala symbol literal results in NoSuchMethod

    - by Benson
    I have recently begun using Scala. I've written a DSL in it which can be used to describe a processing pipeline in medici. In my DSL, I've made use of symbols to signify an anchor, which can be used to put a fork (or a tee, if you prefer) in the pipeline. Here's a small sample program that runs correctly: object Test extends PipelineBuilder { connector("TCP") / Map("tcpProtocol" -> new DirectProtocol()) "tcp://localhost:4858" --> "ByteToStringProcessor" --> Symbol("hello") "stdio://in?promptMessage=enter name:%20" --> Symbol("hello") Symbol("hello") --> "SayHello" / Map("prefix" -> "\n\t") --> "stdio://out" } For some reason, when I use a symbol literal in my program, I get a NoSuchMethod exception at runtime: java.lang.NoSuchMethodError: scala.Symbol.intern()Lscala/Symbol; at gov.pnnl.mif.scaladsl.Test$.<init>(Test.scala:7) at gov.pnnl.mif.scaladsl.Test$.<clinit>(Test.scala) at gov.pnnl.mif.scaladsl.Test.main(Test.scala) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at scala.tools.nsc.ObjectRunner$$anonfun$run$1.apply(ObjectRunner.scala:75) at scala.tools.nsc.ObjectRunner$.withContextClassLoader(ObjectRunner.scala:49) at scala.tools.nsc.ObjectRunner$.run(ObjectRunner.scala:74) at scala.tools.nsc.MainGenericRunner$.main(MainGenericRunner.scala:154) at scala.tools.nsc.MainGenericRunner.main(MainGenericRunner.scala) This happens regardless of how the symbol is used. Specifically, I've tried using the symbol in the pipeline, and in a simple println('foo) statement. The question: What could possibly cause a symbol literal's mere existence to cause a NoSuchMethodError? In my DSL I am using an implicit function which converts symbols to instances of the Anchor class, like so: implicit def makeAnchor(a: Symbol):Anchor = anchor(a) Sadly, my understanding of Scala is weak enough that I can't think of why that might be causing my NoSuchMethodError.

  • C# trying to capture the KeyDown event on a form

    - by Patrick
    Hello! I am creating a small game, the game is printed onto a panel on a windows form. Now i want to capture the keydown event to see if its the arrow keys that has been pressed, the problem however is that i can't seem to capture it. Let me explain, on the form i have 4 buttons and various other controls and if the user for instance press one of the buttons (to trigger a game event) then the button has focus and i can't capture the movements with the arrow keys. I tried something like private void KeyDown(KeyEventArgs e) { if (e.KeyCode == Keys.Left) { game.MovePlayer(DonutWarsLibrary.GameObjects.Direction.E); game.DrawObjects(panel1.CreateGraphics()); } else if (e.KeyCode == Keys.Right) { game.MovePlayer(DonutWarsLibrary.GameObjects.Direction.W); game.DrawObjects(panel1.CreateGraphics()); } else if (e.KeyCode == Keys.Up) { game.MovePlayer(DonutWarsLibrary.GameObjects.Direction.N); game.DrawObjects(panel1.CreateGraphics()); } else if (e.KeyCode == Keys.Down) { game.MovePlayer(DonutWarsLibrary.GameObjects.Direction.S); game.DrawObjects(panel1.CreateGraphics()); } } and then when the form key down event was pressed, i used this private void MainForm_KeyDown(object sender, KeyEventArgs e) { KeyDown(e); } I also added keydown for the buttons and the various other controls on the windows form, but i am not getting any response back. I have setup a breakpoint inside the function to see if it's being called, but that breakpoint never triggers? Any ideas? The most optimal was to have a general KeyDown event that triggers (regardless of what control that currently has focus) and then calls the KeyDown method.

  • MXML composite canvas component initialization error

    - by mkorpela
    I'm getting an odd error from my composite canvas component: An ActionScript error has occurred: Error: null at mx.core::Container/initialize()[C:\autobuild\galaga\frameworks\projects\framework\src\mx\core\Container.as:2560] at -REMOVED THIS FOR STACK OVERFLOW-.view::EditableCanvas/initialize()[.../view/EditableCanvas ....

  • dynamically horizontal scalable key value store

    - by Zubair
    Hi, Is there a key value store that will give me the following: Allow me to simply add and remove nodes and will redstribute the data automatically Allow me to remove nodes and still have 2 extra data nodes to provide redundancy Allow me to store text or images up to 1GB in size Can store small size data up to 100TB of data Fast (so will allow queries to be performed on top of it) Make all this transparent to the client Works on Ubuntu/FreeBSD or Mac Free or open source I basically want something I can use a "single", and not have to worry about having memcached, a db, and several storage components so yes, I do want a database "silver bullet" you could say. Thanks Zubair Answers so far: MogileFS on top of BackBlaze - As far as I can see this is just a filesystem, and after some research it only seems to be appropriate for large image files Tokyo Tyrant - Needs lightcloud. This doesn't auto scale as you add new nodes. I did look into this and it seems it is very fast for queries which fit onto a single node though Riak - This is one I am looking into myself, but I don't have any results yet Amazon S3 - Is anyone using this as their sole persistance layer in production? From what I have seen it seems to be used for storage of images as complex queries are too expensive @shaman suggested Cassandra - definitely one I am looking into So far it seems that there is no database or key value store that fulfills the criteria I mentioned, not even after offering a bounty of 100 points did the question get answered!

  • iPhone OpenGL Splash Screen? How?

    - by Kyle
    My app is based pretty much on the EAGLView in the SDK. It doesn't incorporate a ViewController. Rather it simply inits GL and starts painting immediately.. Currently, my app will load a very small PNG and displays it as quickly as possible. On a 3GS this is rather instant, but on a 3G it can take about 2 seconds. In the latter case of the 3G, the user is looking at a black screen for that time. Is this behavior allowed by Apple? Is there any way to alter this SDK example so that it makes use of 'default.png'? It doesn't seem so straight forward to me. I want my user to see an image as quickly as possible, and I also don't want to be rejected for such a little quirk like this as well. In the guidelines, they encourage you to use default.png for standard applications to show a sort of mockup of the interface while it actually loads. I want to initialize OpenGL, and ALSO display this. This default.png is loaded before the app screen launches. This is EXACLTY what I want to make use of. Any help is appreciated. Thanks!

  • When should I be cautious using about data binding in .NET?

    - by Ben McCormack
    I just started working on a small team of .NET programmers about a month ago and recently got in a discussion with our team lead regarding why we don't use databinding at all in our code. Every time we work with a data grid, we iterate through a data table and populate the grid row by row; the code usually looks something like this: Dim dt as DataTable = FuncLib.GetData("spGetTheData ...") Dim i As Integer For i = 0 To dt.Rows.Length - 1 '(not sure why we do not use a for each here)' gridRow = grid.Rows.Add() gridRow(constantProductID).Value = dt("ProductID").Value gridRow(constantProductDesc).Value = dt("ProductDescription").Value Next '(I am probably missing something in the code, but that is basically it)' Our team lead was saying that he got burned using data binding when working with Sheridan Grid controls, VB6, and ADO recordsets back in the nineties. He's not sure what the exact problem was, but he remembers that binding didn't work as expected and caused him some major problems. Since then, they haven't trusted data binding and load the data for all their controls by hand. The reason the conversation even came up was because I found data binding to be very simple and really liked separating the data presentation (in this case, the data grid) from the in-memory data source (in this case, the data table). "Loading" the data row by row into the grid seemed to break this distinction. I also observed that with the advent of XAML in WPF and Silverlight, data-binding seems like a must-have in order to be able to cleanly wire up a designer's XAML code with your data. When should I be cautious of using data-binding in .NET?

  • Export Multiple Crystal Reports ASP.NET

  • NSTextView's adjustScroll method

    - by Mike
    I'm trying to implement typewriter scrolling in my Cocoa text editor, keeping the insertion point centered vertically in its scrollview. Toward this end, I have subclassed NSClipView to provide a scrollToPointWithoutConstraint method, which scrolls the document to a specified point without calling constrainScrollPoint. This is necessary because for short documents the insertion point can't be centered unless we scroll beyond the document's bounds. This seems reasonably straightforward so far and does what I want. The problem comes in when I try to scroll using the scroll bars. If I'm scrolled to the end of the document, such that part of the scroll view contains an area outside the document's bounds, trying to scroll up by a small increment causes the scroll view to jump, immediately clamping to the document's actual bounds. I gather that I might need to subclass NSTextView and override the adjustScroll method; this is where my actual question begins. The proposedVisibleRect that is passed to adjustScroll already has its dimensions adjusted so that they lie within the document's actual bounds. Is there a way that I can change the value of proposedVisibleRect before adjustScroll is called? Alternatively, am I going about this entirely wrong? Any suggestions would be greatly appreciated at this point.

  • Java UTF-8 to ASCII conversion with supplements

    - by bozo
    Hi, we are accepting all sorts of national characters in UTF-8 string on the input, and we need to convert them to ASCII string on the output for some legacy use. (we don't accept Chinese and Japanese chars, only European languages) We have a small utility to get rid of all the diacritics: public static final String toBaseCharacters(final String sText) { if (sText == null || sText.length() == 0) return sText; final char[] chars = sText.toCharArray(); final int iSize = chars.length; final StringBuilder sb = new StringBuilder(iSize); for (int i = 0; i < iSize; i++) { String sLetter = new String(new char[] { chars[i] }); sLetter = Normalizer.normalize(sLetter, Normalizer.Form.NFC); try { byte[] bLetter = sLetter.getBytes("UTF-8"); sb.append((char) bLetter[0]); } catch (UnsupportedEncodingException e) { } } return sb.toString(); } The question is how to replace all the german sharp s (ß, Ð, d) and other characters that get through the above normalization method, with their supplements (in case of ß, supplement would probably be "ss" and in case od Ð supplement would be either "D" or "Dj"). Is there some simple way to do it, without million of .replaceAll() calls? So for example: Ðonardan = Djonardan, Blaß = Blass and so on. We can replace all "problematic" chars with empty space, but would like to avoid this to make the output as similar to the input as possible. Thank you for your answers, Bozo

  • Make buttonsize bigger for tablet? Android, Xml

  • How Can I Generate Equivalent Output Using the CryptoAPI and the .NET Encryption (TripleDESCryptoSer

    - by S. Butts
    I have some C#/.NET code that encrypts and decrypts data using TripleDES encryption. It sticks to the sample code provided at MSDN pretty closely. The encryption piece looks like the following: TripleDESCryptoServiceProvider _desProvider = new TripleDESCryptoServiceProvider(); //bytes for key and initialization vector //keyBytes is 24 bytes of stuff, vectorBytes is 8 bytes of stuff byte[] keyBytes; byte[] vectorBytes; FileStream fStream = File.Open(locationOfFile, FileMode.Create, FileAccess.Write); CryptoStream cStream = new CryptoStream(fStream, _desProvider.CreateEncryptor(keyBytes, vectorBytes), CryptoStreamMode.Write); BinaryWriter bWriter = new BinaryWriter(cStream); //write out encrypted data //raw data is a few bytes of binary information byte[] rawData; bWriter.Write(rawData); With encrypting and decrypting in C#, this all works like a charm. The problem is I need to write a small Win32 utility that will duplicate the encryption above. I have tried several methods using the CryptoAPI, and I simply do not get output that the .NET piece can decrypt, no matter what I do. Can someone please tell me what the equivalent C++ code is that will produce the same output? I am not certain just what methods of the CryptoAPI the .NET functions use to encrypt the data. What options are used, and what method of generating the key is used? Before someone suggests that I just write it in C# anyway, or create some common library bridge for them, those options are unfortunately off the table. It really has to work in Win32 with .NET and without using a DLL. I have some leeway in changing the C# code. I apologize in advance if this is bone-headed, as I am new to encryption.

  • What is the proper way to align UITableViewCells when only some have an imageView?

    - by Topher Fangio
    Hello all, I am new to iPhone programming and working on my first real application (i.e. one not written in a book or online) and I've run into a small problem which I could solve a multitude of ways, but feel like there should be a good solution that perhaps I am just missing. Here is the scenario: I have a UITableView with a bunch of standard UITableViewCells in it. What I want to do is toggle a green check mark when the cell is selected and I have that part working (note: I'm already using the accessoryType for something else, so I can't use it for the checkmark...besides, it's not as pretty). Unfortunately, when I toggle the checkmark like so: if (...) { cell.imageView.image = [UIImage imageNamed:@"checkmark.png"]; } else { cell.imageView.image = nil; } It makes the cell's label bounce back and forth depending on whether it is checked or not. What is the proper way to align the cell's text (set via cell.textLabel.text) regardless of whether or not it has an image set? The solutions I have come up with are: Create a blank 40x40 png image in Photoshop and set the unchecked to that Create a blank 40x40 image solely in code Set some setting that I don't know about that will align it for me Create a subclass of UITableCellView that does what I need (which would be stupid, I'd just go with option 1...) Suggestions? Thoughts? Comments? Thank you very much :-) P.S. I'd like the solution to work with OS 3.0 and 4.0 if that makes any sort of difference.

  • Minimizing SpringLdap dependencies.

    - by mP
    I would like to use SpringLDAP to do some simple username/password verification for authentication purposes. WHile the actual jar file is quite small (less than 1 meg) it seems to have a lot of dependencies as listed by link text. By alot i mean it seems to suck in over 50 things many which dont seem right such as spring-jdbc as I dont want any jdbc and only the ldap template class and its bare dependencies. Without wasting too much time is it possible to the spring-ldap with only a bare minimum number of dependencies which amount to something like: spring core spring ldap whatever logging deps they require. spring tx I dont see or appreciate why the rest of thes tuff is reuqired and was wondering can anyone verify they arent really needed in the end if one sticks to the basics. The other stuff i am referring too include: spring-orm // no jdbc beans // i dont want ioc. spring-aop // no need for aop. I intend to wire up the beans i will be using manually. I dont want more crap in there for what ammounts to setting a few properties, and want confirmation that I dont need what is probably there just to do the ioc stuff when all i want is the ldap stuff.

  • Filtering Wikipedia's XML dump: error on some accents

    - by streetpc
    I'm trying to index Wikpedia dumps. My SAX parser make Article objects for the XML with only the fields I care about, then send it to my ArticleSink, which produces Lucene Documents. I want to filter special/meta pages like those prefixed with Category: or Wikipedia:, so I made an array of those prefixes and test the title of each page against this array in my ArticleSink, using article.getTitle.startsWith(prefix). In English, everything works fine, I get a Lucene index with all the pages except for the matching prefixes. In French, the prefixes with no accent also work (i.e. filter the corresponding pages), some of the accented prefixes don't work at all (like Catégorie:), and some work most of the time but fail on some pages (like Wikipédia:) but I cannot see any difference between the corresponding lines (in less). I can't really inspect all the differences in the file because of its size (5 GB), but it looks like a correct UTF-8 XML. If I take a portion of the file using grep or head, the accents are correct (even on the incriminated pages, the <title>Catégorie:something</title> is correctly displayed by grep). On the other hand, when I rectreate a wiki XML by tail/head-cutting the original file, the same page (here Catégorie:Rock par ville) gets filtered in the small file, not in the original… Any idea ? Alternatives I tried: Getting the file (commented lines were tried wihtout success): FileInputStream fis = new FileInputStream(new File(xmlFileName)); //ReaderInputStream ris = ReaderInputStream.forceEncodingInputStream(fis, "UTF-8" ); //(custom function opening the stream, reading it as UFT-8 into a Reader and returning another byte stream) //InputSource is = new InputSource( fis ); is.setEncoding("UTF-8"); parser.parse(fis, handler); Filtered prefixes: ignoredPrefix = new String[] {"Catégorie:", "Modèle:", "Wikipédia:", "Cat\uFFFDgorie:", "Mod\uFFFDle:", "Wikip\uFFFDdia:", //invalid char "Catégorie:", "Modèle:", "Wikipédia:", // UTF-8 as ISO-8859-1 "Image:", "Portail:", "Fichier:", "Aide:", "Projet:"}; // those last always work

My first form has 2 submit buttons - one to make the calculation, and one to submit the relevant data to the booking form. I'm stuck trying to make the 2nd button work. Once the API calculation has been made, I get 4 values - From, To, Cost, Distance. I am trying to pass the From, To and Cost values into my booking form by clicking the second button. But I can;t seem to get it to work. I've tried POST and GET but I think I may have been doing something wrong with both. Any help is appreciated. Code for API form: <script type="text/javascript" src="http://maps.google.com/maps?file=api&amp;v=2&amp;key=ABQIAAAAwCUxKrPl8_9WadET5dc4KxTqOwVK5HCwTKtW27PjzpqojXnJORQ2kUsdCksByD4hzcGXiOxvn6C4cw&sensor=true"></script> <script type="text/javascript"> var geocoder = null; var location1 = null; var location2 = null; var gDir = null; var directions = null; var total = 0; function roundNumber(num, dec) { var result = Math.floor(num*Math.pow(10 ,dec))/Math.pow(10,dec); return result; } function from(form) { address1=form.start.options[form.start.selectedIndex].value form.address1.value=address1 form.address1.focus() } function to(form) { address2=form.end.options[form.end.selectedIndex].value form.address2.value=address2 form.address2.focus() } function initialize() { var map = new GMap2(document.getElementById("map_canvas")); map.setCenter(new GLatLng(54.019066,-1.381531),9); map.setMapType(G_NORMAL_MAP); geocoder = new GClientGeocoder(); gDir = new GDirections(map); GEvent.addListener(gDir, "load", function() { var drivingDistanceMiles = gDir.getDistance().meters / 1609.344; var drivingDistanceKilometers = gDir.getDistance().meters / 1000; var miles = drivingDistanceMiles.toFixed(0); //var cost = (((miles - 1) * 1.9) + 3.6).toFixed(2); var meters = gDir.getDistance().meters.toFixed(1); if(miles < 70){ var cost = miles *1.75; } if(miles >70){ var cost = miles *1.2; } document.getElementById('from').innerHTML = '<strong>From: </strong>' + location1.address; document.getElementById('to').innerHTML = '<strong>To: </strong>' + location2.address; document.getElementById('cost').innerHTML = '<span class="fare"><strong>Estimated Taxi FARE:</strong>' + ' £' + cost.toFixed(2) + '</span>'; document.getElementById('miles').innerHTML = '<strong>Distance: </strong>' + miles + ' Miles'; }); } function showLocation() // start of possible values for address not recognized on google search // values for address1 { if (document.forms[0].address1.value == "heathrow" || document.forms[0].address1.value == "Heathrow" || document.forms[0].address1.value == "heathrow airport" || document.forms[0].address1.value == "Heathrow Airport" || document.forms[0].address1.value == "London Heathrow" || document.forms[0].address1.value =="london heathrow" ) { (document.forms[0].address1.value = "Heathrow Airport"); } if (document.forms[0].address2.value == "heathrow" || document.forms[0].address2.value == "Heathrow" || document.forms[0].address2.value == "heathrow airport" || document.forms[0].address2.value == "Heathrow Airport" || document.forms[0].address2.value == "London Heathrow" || document.forms[0].address2.value =="london heathrow" ) { (document.forms[0].address2.value = "Heathrow Airport"); } geocoder.getLocations(document.forms[0].address1.value + document.forms[0].uk.value || document.forms[0].start.value + document.forms[0].uk.value, function (response) { if (!response || response.Status.code != 200) { alert("Sorry, we were unable to find the first address"); } else { location1 = {lat: response.Placemark[0].Point.coordinates[1], lon: response.Placemark[0].Point.coordinates[0], address: response.Placemark[0].address}; geocoder.getLocations(document.forms[0].address2.value + document.forms[0].uk.value, function (response) { if (!response || response.Status.code != 200) { alert("Sorry, we were unable to find the second address"); } else { location2 = {lat: response.Placemark[0].Point.coordinates[1], lon: response.Placemark[0].Point.coordinates[0], address: response.Placemark[0].address}; gDir.load('from: ' + location1.address + ' to: ' + location2.address); } }); } }); } </script> <style> #quote { font-family: Georgia, "Times New Roman", Times, serif; } </style> </head> <body style="background-color: rgb(255, 255, 255);" onUnload="GUnload()" onLoad="initialize()"> <div id="sidebar"> <!--MAPS--> <div id="calc_top"></div> <div id="calc_body"> <div id="calc_inside"> <span style="font-size: 16px; font-weight: bold;">Get A Quote Now</span> <p class="disclaimer">Fares can be calculated using either Area, Exact Address or Postcode, when entering address please include both road name and area i.e. <em>Harrogate Road, Ripon</em>.

  • onsubmit() does not work.

    - by the Hampster
    Here is something that I find disturbing. I created a small form, and I'm using AJAX to validate for me. I have a javascript function authenticate() that works sometimes. <form method="post" action="" id="login_form" onsubmit="authenticate()";> // various inputs <input type="button" onclick="authenticate()" value="Log In"> </form> authenticate() works just fine when I click the button. However, if I press enter the form is submitted, and it fails. It also fails if I call onSubmit(). In my debugging, I alert the outgoing texts-- they are identical. However, the Prototype Ajax function calls it the onSuccess, but there is just no response from the server. (The server outputs either "Success" or "Failure"). Why the different behaviors for onClick() vs onSubmit()? The exact same function is called, but the results are different. Any help would be appreciated. --Dave

  • GRAPH PROBLEM: find an algorithm to determine the shortest path from one point to another in a recta

    - by newba
    I'm getting such an headache trying to elaborate an appropriate algorithm to go from a START position to a EXIT position in a maze. For what is worth, the maze is rectangular, maxsize 500x500 and, in theory, is resolvable by DFS with some branch and bound techniques ... 10 3 4 7 6 3 3 1 2 2 1 0 2 2 2 4 2 2 5 2 2 1 3 0 2 2 2 2 1 3 3 4 2 3 4 4 3 1 1 3 1 2 2 4 2 2 1 Output: 5 1 4 2 Explanation: Our agent looses energy every time he gives a step and he can only move UP, DOWN, LEFT and RIGHT. Also, if the agent arrives with a remaining energy of zero or less, he dies, so we print something like "Impossible". So, in the input 10 is the initial agent's energy, 3 4 is the START position (i.e. column 3, line 4) and we have a maze 7x6. Think this as a kind of labyrinth, in which I want to find the exit that gives the agent a better remaining energy (shortest path). In case there are paths which lead to the same remaining energy, we choose the one which has the small number of steps, of course. I need to know if a DFS to a maze 500x500 in the worst case is feasible with these limitations and how to do it, storing the remaining energy in each step and the number of steps taken so far. The output means the agent arrived with remaining energy= 5 to the exit pos 1 4 in 2 steps. If we look carefully, in this maze it's also possible to exit at pos 3 1 (column 3, row 1) with the same energy but with 3 steps, so we choose the better one. With these in mind, can someone help me some code or pseudo-code? I have troubles working this around with a 2D array and how to store the remaining energy, the path (or number of steps taken)....

  • Disabling redraw in WinForms app

    - by Ryan
    I'm working on a C#.Net application which has a somewhat annoying bug in it. The main window has a number of tabs, each of which has a grid on it. When switching from one tab to another, or selecting a different row in a grid, it does some background processing, and during this the menu flickers as it's redrawn (File, Help, etc menu items as well as window icon and title). I tried disabling the redraw on the window while switching tabs/rows (WM_SETREDRAW message) at first. In one case, it works perfectly. In the other, it solves the immediate bug (title/menu flicker), but between disabling the redraw and enabling it again, the window is "transparent" to mouse clicks - there's a small window (<1 sec) in which I can click and it will, say, highlight an icon on my desktop, as if the app wasn't there at all. If I have something else running in the background (Firefox, say) it will actually get focus when clicked (and draw part of the browser, say the address bar.) Here's code I added. m = new Message(); m.HWnd = System.Windows.Forms.Application.OpenForms[0].Handle; //top level m.WParam = (IntPtr)0; //disable redraw m.LParam = (IntPtr)0; //unused m.Msg = 11; //wm_setredraw WndProc(ref m); <snip - Application ignores clicks while in this section (in one case) m = new Message(); m.HWnd = System.Windows.Forms.Application.OpenForms[0].Handle; //top level m.WParam = (IntPtr)1; //enable m.LParam = (IntPtr)0; //unused m.Msg = 11; //wm_setredraw WndProc(ref m); System.Windows.Forms.Application.OpenForms[0].Refresh(); Does anyone know if a) there's a way to fix the transparent-application problem here, or b) if I'm doing it wrong in the first place and this should be fixed some other way?

  • Empty UIView with minimal drawRect: overhead

    - by Benjohn Barnes
    Hi, I have an application that has three nested views that are mechanically important, but have no visual elements: A vanila UIView that doesn't have any content of its own, and is simply used as a host for CALayers. A UIScrollView (that is queried for it's origin and used to position CALayers in 3d: I really only use this view to faithfully replicate the scroll view's "mechanics"), The scroll view's contents: a UIView subclass. It simply picks up touch events and passes them to a delegate - all that is important are its UIResponder machinery. The UIView hosting CALayers is a sibling of a UIImageView that is a background image over which the CALayers are drawn. I'd really like to ensure that none of these empty UIViews have any drawing or compositing overhead (in time, or storage) associated with them, or if that's not possible, to get this overhead as small as possible, and to understand it so that I can perhaps decide if I should try a different approach. In interface builder, I've set all of the views to not clear their context before drawing. I've not set them to be opaque though, because they definitely are not opaque - they are completely transparent. I've found that I need to give the scroll view contents a transparent clear colour (again in IB by setting the background colour's opacity to zero), and this suggests that it is being drawn, which I don't want. So, in short, I've not got much idea of what is and isn't getting drawn (anyone know of a tool like Quartz Debug for iPhone / simulator?), or how to go about stopping things from getting drawn. Advice would be very welcome! Thanks, Benjohn

  • The IOC "child" container / Service Locator

    - by Mystagogue
    DISCLAIMER: I know there is debate between DI and service locator patterns. I have a question that is intended to avoid the debate. This question is for the service locator fans, who happen to think like Fowler "DI...is hard to understand...on the whole I prefer to avoid it unless I need it." For the purposes of my question, I must avoid DI (reasons intentionally not given), so I'm not trying to spark a debate unrelated to my question. QUESTION: The only issue I might see with keeping my IOC container in a singleton (remember my disclaimer above), is with the use of child containers. Presumably the child containers would not themselves be singletons. At first I thought that poses a real problem. But as I thought about it, I began to think that is precisely the behavior I want (the child containers are not singletons, and can be Disposed() at will). Then my thoughts went further into a philosophical realm. Because I'm a service locator fan, I'm wondering just how necessary the notion of a child container is in the first place. In a small set of cases where I've seen the usefulness, it has either been to satisfy DI (which I'm mostly avoiding anyway), or the issue was solvable without recourse to the IOC container. My thoughts were partly inspired by the IServiceLocator interface which doesn't even bother to list a "GetChildContainer" method. So my question is just that: if you are a service locator fan, have you found that child containers are usually moot? Otherwise, when have they been essential? extra credit: If there are other philosophical issues with service locator in a singleton (aside from those posed by DI advocates), what are they?

  • Partial template specialization on a class

    - by Jonathan Swinney
    I'm looking for a better way to this. I have a chunk of code that needs to handle several different objects that contain different types. The structure that I have looks like this: class Base { // some generic methods } template <typename T> class TypedBase : public Base { // common code with template specialization private: std::map<int,T> mapContainingSomeDataOfTypeT; } template <> class TypedBase<std::string> : public Base { // common code with template specialization public: void set( std::string ); // functions not needed for other types std::string get(); private: std::map<int,std::string> mapContainingSomeDataOfTypeT; // some data not needed for other types } Now I need to add some additional functionality that only applies to one of the derivative classes. Specifically the std::string derivation, but the type doesn't actually matter. The class is big enough that I would prefer not copy the whole thing simply to specialize a small part of it. I need to add a couple of functions (and accessor and modifier) and modify the body of several of the other functions. Is there a better way to accomplish this?
