display alert when mouse hovers over word in text

- by user1672790

I have been struggling with this for a few days. I need somebody to steer me in the right direction. I have been searching on the web. I am not sure if I took the right approach. What I need is that each time a person hovers over a particular keyword, it should display an alert box. In this example the word is else. When I run the code it does not give any errors and does not display anything when mouse hovers on the word. function on_func2() { var searchString = 'else'; var elements = document.getElementById('paragraph2'); for (var i = 0; i < elements.length; i++) { if (elements[i].innerHTML.indexOf(searchString) !== -1) { alert('Match'); break; } } }

Do I have to write my own IsNumeric function?

- by cf_PhillipSenn

I found this function: function IsNumeric(sText) { var ValidChars = "0123456789."; var IsNumber=true; var Char; for (i = 0; i < sText.length && IsNumber == true; i++) { Char = sText.charAt(i); if (ValidChars.indexOf(Char) == -1){ IsNumber = false; } } return IsNumber; }; Q: Isn't there a built-in JavaScript function for isNumeric? Something like val()?

Using FiddlerCore to capture HTTP Requests with .NET

- by Rick Strahl

Over the last few weeks I’ve been working on my Web load testing utility West Wind WebSurge. One of the key components of a load testing tool is the ability to capture URLs effectively so that you can play them back later under load. One of the options in WebSurge for capturing URLs is to use its built-in capture tool which acts as an HTTP proxy to capture any HTTP and HTTPS traffic from most Windows HTTP clients, including Web Browsers as well as standalone Windows applications and services. To make this happen, I used Eric Lawrence’s awesome FiddlerCore library, which provides most of the functionality of his desktop Fiddler application, all rolled into an easy to use library that you can plug into your own applications. FiddlerCore makes it almost too easy to capture HTTP content! For WebSurge I needed to capture all HTTP traffic in order to capture the full HTTP request – URL, headers and any content posted by the client. The result of what I ended up creating is this semi-generic capture form: In this post I’m going to demonstrate how easy it is to use FiddlerCore to build this HTTP Capture Form. If you want to jump right in here are the links to get Telerik’s Fiddler Core and the code for the demo provided here. FiddlerCore Download FiddlerCore on NuGet Show me the Code (WebSurge Integration code from GitHub) Download the WinForms Sample Form West Wind Web Surge (example implementation in live app) Note that FiddlerCore is bound by a license for commercial usage – see license.txt in the FiddlerCore distribution for details. Integrating FiddlerCore FiddlerCore is a library that simply plugs into your application. You can download it from the Telerik site and manually add the assemblies to your project, or you can simply install the NuGet package via: PM> Install-Package FiddlerCore The library consists of the FiddlerCore.dll as well as a couple of support libraries (CertMaker.dll and BCMakeCert.dll) that are used for installing SSL certificates. I’ll have more on SSL captures and certificate installation later in this post. But first let’s see how easy it is to use FiddlerCore to capture HTTP content by looking at how to build the above capture form. Capturing HTTP Content Once the library is installed it’s super easy to hook up Fiddler functionality. Fiddler includes a number of static class methods on the FiddlerApplication object that can be called to hook up callback events as well as actual start monitoring HTTP URLs. In the following code directly lifted from WebSurge, I configure a few filter options on Form level object, from the user inputs shown on the form by assigning it to a capture options object. In the live application these settings are persisted configuration values, but in the demo they are one time values initialized and set on the form. Once these options are set, I hook up the AfterSessionComplete event to capture every URL that passes through the proxy after the request is completed and start up the Proxy service:void Start() { if (tbIgnoreResources.Checked) CaptureConfiguration.IgnoreResources = true; else CaptureConfiguration.IgnoreResources = false; string strProcId = txtProcessId.Text; if (strProcId.Contains('-')) strProcId = strProcId.Substring(strProcId.IndexOf('-') + 1).Trim(); strProcId = strProcId.Trim(); int procId = 0; if (!string.IsNullOrEmpty(strProcId)) { if (!int.TryParse(strProcId, out procId)) procId = 0; } CaptureConfiguration.ProcessId = procId; CaptureConfiguration.CaptureDomain = txtCaptureDomain.Text; FiddlerApplication.AfterSessionComplete += FiddlerApplication_AfterSessionComplete; FiddlerApplication.Startup(8888, true, true, true); } The key lines for FiddlerCore are just the last two lines of code that include the event hookup code as well as the Startup() method call. Here I only hook up to the AfterSessionComplete event but there are a number of other events that hook various stages of the HTTP request cycle you can also hook into. Other events include BeforeRequest, BeforeResponse, RequestHeadersAvailable, ResponseHeadersAvailable and so on. In my case I want to capture the request data and I actually have several options to capture this data. AfterSessionComplete is the last event that fires in the request sequence and it’s the most common choice to capture all request and response data. I could have used several other events, but AfterSessionComplete is one place where you can look both at the request and response data, so this will be the most common place to hook into if you’re capturing content. The implementation of AfterSessionComplete is responsible for capturing all HTTP request headers and it looks something like this:private void FiddlerApplication_AfterSessionComplete(Session sess) { // Ignore HTTPS connect requests if (sess.RequestMethod == "CONNECT") return; if (CaptureConfiguration.ProcessId > 0) { if (sess.LocalProcessID != 0 && sess.LocalProcessID != CaptureConfiguration.ProcessId) return; } if (!string.IsNullOrEmpty(CaptureConfiguration.CaptureDomain)) { if (sess.hostname.ToLower() != CaptureConfiguration.CaptureDomain.Trim().ToLower()) return; } if (CaptureConfiguration.IgnoreResources) { string url = sess.fullUrl.ToLower(); var extensions = CaptureConfiguration.ExtensionFilterExclusions; foreach (var ext in extensions) { if (url.Contains(ext)) return; } var filters = CaptureConfiguration.UrlFilterExclusions; foreach (var urlFilter in filters) { if (url.Contains(urlFilter)) return; } } if (sess == null || sess.oRequest == null || sess.oRequest.headers == null) return; string headers = sess.oRequest.headers.ToString(); var reqBody = sess.GetRequestBodyAsString(); // if you wanted to capture the response //string respHeaders = session.oResponse.headers.ToString(); //var respBody = session.GetResponseBodyAsString(); // replace the HTTP line to inject full URL string firstLine = sess.RequestMethod + " " + sess.fullUrl + " " + sess.oRequest.headers.HTTPVersion; int at = headers.IndexOf("\r\n"); if (at < 0) return; headers = firstLine + "\r\n" + headers.Substring(at + 1); string output = headers + "\r\n" + (!string.IsNullOrEmpty(reqBody) ? reqBody + "\r\n" : string.Empty) + Separator + "\r\n\r\n"; BeginInvoke(new Action<string>((text) => { txtCapture.AppendText(text); UpdateButtonStatus(); }), output); } The code starts by filtering out some requests based on the CaptureOptions I set before the capture is started. These options/filters are applied when requests actually come in. This is very useful to help narrow down the requests that are captured for playback based on options the user picked. I find it useful to limit requests to a certain domain for captures, as well as filtering out some request types like static resources – images, css, scripts etc. This is of course optional, but I think it’s a common scenario and WebSurge makes good use of this feature. AfterSessionComplete like other FiddlerCore events, provides a Session object parameter which contains all the request and response details. There are oRequest and oResponse objects to hold their respective data. In my case I’m interested in the raw request headers and body only, as you can see in the commented code you can also retrieve the response headers and body. Here the code captures the request headers and body and simply appends the output to the textbox on the screen. Note that the Fiddler events are asynchronous, so in order to display the content in the UI they have to be marshaled back the UI thread with BeginInvoke, which here simply takes the generated headers and appends it to the existing textbox test on the form. As each request is processed, the headers are captured and appended to the bottom of the textbox resulting in a Session HTTP capture in the format that Web Surge internally supports, which is basically raw request headers with a customized 1st HTTP Header line that includes the full URL rather than a server relative URL. When the capture is done the user can either copy the raw HTTP session to the clipboard, or directly save it to file. This raw capture format is the same format WebSurge and also Fiddler use to import/export request data. While this code is application specific, it demonstrates the kind of logic that you can easily apply to the request capture process, which is one of the reasonsof why FiddlerCore is so powerful. You get to choose what content you want to look up as part of your own application logic and you can then decide how to capture or use that data as part of your application. The actual captured data in this case is only a string. The user can edit the data by hand or in the the case of WebSurge, save it to disk and automatically open the captured session as a new load test. Stopping the FiddlerCore Proxy Finally to stop capturing requests you simply disconnect the event handler and call the FiddlerApplication.ShutDown() method:void Stop() { FiddlerApplication.AfterSessionComplete -= FiddlerApplication_AfterSessionComplete; if (FiddlerApplication.IsStarted()) FiddlerApplication.Shutdown(); } As you can see, adding HTTP capture functionality to an application is very straight forward. FiddlerCore offers tons of features I’m not even touching on here – I suspect basic captures are the most common scenario, but a lot of different things can be done with FiddlerCore’s simple API interface. Sky’s the limit! The source code for this sample capture form (WinForms) is provided as part of this article. Adding Fiddler Certificates with FiddlerCore One of the sticking points in West Wind WebSurge has been that if you wanted to capture HTTPS/SSL traffic, you needed to have the full version of Fiddler and have HTTPS decryption enabled. Essentially you had to use Fiddler to configure HTTPS decryption and the associated installation of the Fiddler local client certificate that is used for local decryption of incoming SSL traffic. While this works just fine, requiring to have Fiddler installed and then using a separate application to configure the SSL functionality isn’t ideal. Fortunately FiddlerCore actually includes the tools to register the Fiddler Certificate directly using FiddlerCore. Why does Fiddler need a Certificate in the first Place? Fiddler and FiddlerCore are essentially HTTP proxies which means they inject themselves into the HTTP conversation by re-routing HTTP traffic to a special HTTP port (8888 by default for Fiddler) and then forward the HTTP data to the original client. Fiddler injects itself as the system proxy in using the WinInet Windows settings which are the same settings that Internet Explorer uses and that are configured in the Windows and Internet Explorer Internet Settings dialog. Most HTTP clients running on Windows pick up and apply these system level Proxy settings before establishing new HTTP connections and that’s why most clients automatically work once Fiddler – or FiddlerCore/WebSurge are running. For plain HTTP requests this just works – Fiddler intercepts the HTTP requests on the proxy port and then forwards them to the original port (80 for HTTP and 443 for SSL typically but it could be any port). For SSL however, this is not quite as simple – Fiddler can easily act as an HTTPS/SSL client to capture inbound requests from the server, but when it forwards the request to the client it has to also act as an SSL server and provide a certificate that the client trusts. This won’t be the original certificate from the remote site, but rather a custom local certificate that effectively simulates an SSL connection between the proxy and the client. If there is no custom certificate configured for Fiddler the SSL request fails with a certificate validation error. The key for this to work is that a custom certificate has to be installed that the HTTPS client trusts on the local machine. For a much more detailed description of the process you can check out Eric Lawrence’s blog post on Certificates. If you’re using the desktop version of Fiddler you can install a local certificate into the Windows certificate store. Fiddler proper does this from the Options menu: This operation does several things: It installs the Fiddler Root Certificate It sets trust to this Root Certificate A new client certificate is generated for each HTTPS site monitored Certificate Installation with FiddlerCore You can also provide this same functionality using FiddlerCore which includes a CertMaker class. Using CertMaker is straight forward to use and it provides an easy way to create some simple helpers that can install and uninstall a Fiddler Root certificate:public static bool InstallCertificate() { if (!CertMaker.rootCertExists()) { if (!CertMaker.createRootCert()) return false; if (!CertMaker.trustRootCert()) return false; } return true; } public static bool UninstallCertificate() { if (CertMaker.rootCertExists()) { if (!CertMaker.removeFiddlerGeneratedCerts(true)) return false; } return true; } InstallCertificate() works by first checking whether the root certificate is already installed and if it isn’t goes ahead and creates a new one. The process of creating the certificate is a two step process – first the actual certificate is created and then it’s moved into the certificate store to become trusted. I’m not sure why you’d ever split these operations up since a cert created without trust isn’t going to be of much value, but there are two distinct steps. When you trigger the trustRootCert() method, a message box will pop up on the desktop that lets you know that you’re about to trust a local private certificate. This is a security feature to ensure that you really want to trust the Fiddler root since you are essentially installing a man in the middle certificate. It’s quite safe to use this generated root certificate, because it’s been specifically generated for your machine and thus is not usable from external sources, the only way to use this certificate in a trusted way is from the local machine. IOW, unless somebody has physical access to your machine, there’s no useful way to hijack this certificate and use it for nefarious purposes (see Eric’s post for more details). Once the Root certificate has been installed, FiddlerCore/Fiddler create new certificates for each site that is connected to with HTTPS. You can end up with quite a few temporary certificates in your certificate store. To uninstall you can either use Fiddler and simply uncheck the Decrypt HTTPS traffic option followed by the remove Fiddler certificates button, or you can use FiddlerCore’s CertMaker.removeFiddlerGeneratedCerts() which removes the root cert and any of the intermediary certificates Fiddler created. Keep in mind that when you uninstall you uninstall the certificate for both FiddlerCore and Fiddler, so use UninstallCertificate() with care and realize that you might affect the Fiddler application’s operation by doing so as well. When to check for an installed Certificate Note that the check to see if the root certificate exists is pretty fast, while the actual process of installing the certificate is a relatively slow operation that even on a fast machine takes a few seconds. Further the trust operation pops up a message box so you probably don’t want to install the certificate repeatedly. Since the check for the root certificate is fast, you can easily put a call to InstallCertificate() in any capture startup code – in which case the certificate installation only triggers when a certificate is in fact not installed. Personally I like to make certificate installation explicit – just like Fiddler does, so in WebSurge I use a small drop down option on the menu to install or uninstall the SSL certificate: This code calls the InstallCertificate and UnInstallCertificate functions respectively – the experience with this is similar to what you get in Fiddler with the extra dialog box popping up to prompt confirmation for installation of the root certificate. Once the cert is installed you can then capture SSL requests. There’s a gotcha however… Gotcha: FiddlerCore Certificates don’t stick by Default When I originally tried to use the Fiddler certificate installation I ran into an odd problem. I was able to install the certificate and immediately after installation was able to capture HTTPS requests. Then I would exit the application and come back in and try the same HTTPS capture again and it would fail due to a missing certificate. CertMaker.rootCertExists() would return false after every restart and if re-installed the certificate a new certificate would get added to the certificate store resulting in a bunch of duplicated root certificates with different keys. What the heck? CertMaker and BcMakeCert create non-sticky CertificatesI turns out that FiddlerCore by default uses different components from what the full version of Fiddler uses. Fiddler uses a Windows utility called MakeCert.exe to create the Fiddler Root certificate. FiddlerCore however installs the CertMaker.dll and BCMakeCert.dll assemblies, which use a different crypto library (Bouncy Castle) for certificate creation than MakeCert.exe which uses the Windows Crypto API. The assemblies provide support for non-windows operation for Fiddler under Mono, as well as support for some non-Windows certificate platforms like iOS and Android for decryption. The bottom line is that the FiddlerCore provided bouncy castle assemblies are not sticky by default as the certificates created with them are not cached as they are in Fiddler proper. To get certificates to ‘stick’ you have to explicitly cache the certificates in Fiddler’s internal preferences. A cache aware version of InstallCertificate looks something like this:public static bool InstallCertificate() { if (!CertMaker.rootCertExists()) { if (!CertMaker.createRootCert()) return false; if (!CertMaker.trustRootCert()) return false; App.Configuration.UrlCapture.Cert = FiddlerApplication.Prefs.GetStringPref("fiddler.certmaker.bc.cert", null); App.Configuration.UrlCapture.Key = FiddlerApplication.Prefs.GetStringPref("fiddler.certmaker.bc.key", null); } return true; } public static bool UninstallCertificate() { if (CertMaker.rootCertExists()) { if (!CertMaker.removeFiddlerGeneratedCerts(true)) return false; } App.Configuration.UrlCapture.Cert = null; App.Configuration.UrlCapture.Key = null; return true; } In this code I store the Fiddler cert and private key in an application configuration settings that’s stored with the application settings (App.Configuration.UrlCapture object). These settings automatically persist when WebSurge is shut down. The values are read out of Fiddler’s internal preferences store which is set after a new certificate has been created. Likewise I clear out the configuration settings when the certificate is uninstalled. In order for these setting to be used you have to also load the configuration settings into the Fiddler preferences *before* a call to rootCertExists() is made. I do this in the capture form’s constructor:public FiddlerCapture(StressTestForm form) { InitializeComponent(); CaptureConfiguration = App.Configuration.UrlCapture; MainForm = form; if (!string.IsNullOrEmpty(App.Configuration.UrlCapture.Cert)) { FiddlerApplication.Prefs.SetStringPref("fiddler.certmaker.bc.key", App.Configuration.UrlCapture.Key); FiddlerApplication.Prefs.SetStringPref("fiddler.certmaker.bc.cert", App.Configuration.UrlCapture.Cert); }} This is kind of a drag to do and not documented anywhere that I could find, so hopefully this will save you some grief if you want to work with the stock certificate logic that installs with FiddlerCore. MakeCert provides sticky Certificates and the same functionality as Fiddler But there’s actually an easier way. If you want to skip the above Fiddler preference configuration code in your application you can choose to distribute MakeCert.exe instead of certmaker.dll and bcmakecert.dll. When you use MakeCert.exe, the certificates settings are stored in Windows so they are available without any custom configuration inside of your application. It’s easier to integrate and as long as you run on Windows and you don’t need to support iOS or Android devices is simply easier to deal with. To integrate into your project, you can remove the reference to CertMaker.dll (and the BcMakeCert.dll assembly) from your project. Instead copy MakeCert.exe into your output folder. To make sure MakeCert.exe gets pushed out, include MakeCert.exe in your project and set the Build Action to None, and Copy to Output Directory to Copy if newer. Note that the CertMaker.dll reference in the project has been removed and on disk the files for Certmaker.dll, as well as the BCMakeCert.dll files on disk. Keep in mind that these DLLs are resources of the FiddlerCore NuGet package, so updating the package may end up pushing those files back into your project. Once MakeCert.exe is distributed FiddlerCore checks for it first before using the assemblies so as long as MakeCert.exe exists it’ll be used for certificate creation (at least on Windows). Summary FiddlerCore is a pretty sweet tool, and it’s absolutely awesome that we get to plug in most of the functionality of Fiddler right into our own applications. A few years back I tried to build this sort of functionality myself for an app and ended up giving up because it’s a big job to get HTTP right – especially if you need to support SSL. FiddlerCore now provides that functionality as a turnkey solution that can be plugged into your own apps easily. The only downside is FiddlerCore’s documentation for more advanced features like certificate installation which is pretty sketchy. While for the most part FiddlerCore’s feature set is easy to work with without any documentation, advanced features are often not intuitive to gleam by just using Intellisense or the FiddlerCore help file reference (which is not terribly useful). While Eric Lawrence is very responsive on his forum and on Twitter, there simply isn’t much useful documentation on Fiddler/FiddlerCore available online. If you run into trouble the forum is probably the first place to look and then ask a question if you can’t find the answer. The best documentation you can find is Eric’s Fiddler Book which covers a ton of functionality of Fiddler and FiddlerCore. The book is a great reference to Fiddler’s feature set as well as providing great insights into the HTTP protocol. The second half of the book that gets into the innards of HTTP is an excellent read for anybody who wants to know more about some of the more arcane aspects and special behaviors of HTTP – it’s well worth the read. While the book has tons of information in a very readable format, it’s unfortunately not a great reference as it’s hard to find things in the book and because it’s not available online you can’t electronically search for the great content in it. But it’s hard to complain about any of this given the obvious effort and love that’s gone into this awesome product for all of these years. A mighty big thanks to Eric Lawrence for having created this useful tool that so many of us use all the time, and also to Telerik for picking up Fiddler/FiddlerCore and providing Eric the resources to support and improve this wonderful tool full time and keeping it free for all.

Introducing the Earthquake Locator – A Bing Maps Silverlight Application, part 1

- by Bobby Diaz

Update: Live demo and source code now available! The recent wave of earthquakes (no pun intended) being reported in the news got me wondering about the frequency and severity of earthquakes around the world. Since I’ve been doing a lot of Silverlight development lately, I decided to scratch my curiosity with a nice little Bing Maps application that will show the location and relative strength of recent seismic activity. Here is a list of technologies this application will utilize, so be sure to have everything downloaded and installed if you plan on following along. Silverlight 3 WCF RIA Services Bing Maps Silverlight Control * Managed Extensibility Framework (optional) MVVM Light Toolkit (optional) log4net (optional) * If you are new to Bing Maps or have not signed up for a Developer Account, you will need to visit www.bingmapsportal.com to request a Bing Maps key for your application. Getting Started We start out by creating a new Silverlight Application called EarthquakeLocator and specify that we want to automatically create the Web Application Project with RIA Services enabled. I cleaned up the web app by removing the Default.aspx and EarthquakeLocatorTestPage.html. Then I renamed the EarthquakeLocatorTestPage.aspx to Default.aspx and set it as my start page. I also set the development server to use a specific port, as shown below. RIA Services Next, I created a Services folder in the EarthquakeLocator.Web project and added a new Domain Service Class called EarthquakeService.cs. This is the RIA Services Domain Service that will provide earthquake data for our client application. I am not using LINQ to SQL or Entity Framework, so I will use the <empty domain service class> option. We will be pulling data from an external Atom feed, but this example could just as easily pull data from a database or another web service. This is an important distinction to point out because each scenario I just mentioned could potentially use a different Domain Service base class (i.e. LinqToSqlDomainService<TDataContext>). Now we can start adding Query methods to our EarthquakeService that pull data from the USGS web site. Here is the complete code for our service class: using System; using System.Collections.Generic; using System.IO; using System.Linq; using System.ServiceModel.Syndication; using System.Web.DomainServices; using System.Web.Ria; using System.Xml; using log4net; using EarthquakeLocator.Web.Model; namespace EarthquakeLocator.Web.Services { /// <summary> /// Provides earthquake data to client applications. /// </summary> [EnableClientAccess()] public class EarthquakeService : DomainService { private static readonly ILog log = LogManager.GetLogger(typeof(EarthquakeService)); // USGS Data Feeds: http://earthquake.usgs.gov/earthquakes/catalogs/ private const string FeedForPreviousDay = "http://earthquake.usgs.gov/earthquakes/catalogs/1day-M2.5.xml"; private const string FeedForPreviousWeek = "http://earthquake.usgs.gov/earthquakes/catalogs/7day-M2.5.xml"; /// <summary> /// Gets the earthquake data for the previous week. /// </summary> /// <returns>A queryable collection of <see cref="Earthquake"/> objects.</returns> public IQueryable<Earthquake> GetEarthquakes() { var feed = GetFeed(FeedForPreviousWeek); var list = new List<Earthquake>(); if ( feed != null ) { foreach ( var entry in feed.Items ) { var quake = CreateEarthquake(entry); if ( quake != null ) { list.Add(quake); } } } return list.AsQueryable(); } /// <summary> /// Creates an <see cref="Earthquake"/> object for each entry in the Atom feed. /// </summary> /// <param name="entry">The Atom entry.</param> /// <returns></returns> private Earthquake CreateEarthquake(SyndicationItem entry) { Earthquake quake = null; string title = entry.Title.Text; string summary = entry.Summary.Text; string point = GetElementValue<String>(entry, "point"); string depth = GetElementValue<String>(entry, "elev"); string utcTime = null; string localTime = null; string depthDesc = null; double? magnitude = null; double? latitude = null; double? longitude = null; double? depthKm = null; if ( !String.IsNullOrEmpty(title) && title.StartsWith("M") ) { title = title.Substring(2, title.IndexOf(',')-3).Trim(); magnitude = TryParse(title); } if ( !String.IsNullOrEmpty(point) ) { var values = point.Split(' '); if ( values.Length == 2 ) { latitude = TryParse(values[0]); longitude = TryParse(values[1]); } } if ( !String.IsNullOrEmpty(depth) ) { depthKm = TryParse(depth); if ( depthKm != null ) { depthKm = Math.Round((-1 * depthKm.Value) / 100, 2); } } if ( !String.IsNullOrEmpty(summary) ) { summary = summary.Replace("</p>", ""); var values = summary.Split( new string[] { "<p>" }, StringSplitOptions.RemoveEmptyEntries); if ( values.Length == 3 ) { var times = values[1].Split( new string[] { "<br>" }, StringSplitOptions.RemoveEmptyEntries); if ( times.Length > 0 ) { utcTime = times[0]; } if ( times.Length > 1 ) { localTime = times[1]; } depthDesc = values[2]; depthDesc = "Depth: " + depthDesc.Substring(depthDesc.IndexOf(":") + 2); } } if ( latitude != null && longitude != null ) { quake = new Earthquake() { Id = entry.Id, Title = entry.Title.Text, Summary = entry.Summary.Text, Date = entry.LastUpdatedTime.DateTime, Url = entry.Links.Select(l => Path.Combine(l.BaseUri.OriginalString, l.Uri.OriginalString)).FirstOrDefault(), Age = entry.Categories.Where(c => c.Label == "Age") .Select(c => c.Name).FirstOrDefault(), Magnitude = magnitude.GetValueOrDefault(), Latitude = latitude.GetValueOrDefault(), Longitude = longitude.GetValueOrDefault(), DepthInKm = depthKm.GetValueOrDefault(), DepthDesc = depthDesc, UtcTime = utcTime, LocalTime = localTime }; } return quake; } private T GetElementValue<T>(SyndicationItem entry, String name) { var el = entry.ElementExtensions.Where(e => e.OuterName == name).FirstOrDefault(); T value = default(T); if ( el != null ) { value = el.GetObject<T>(); } return value; } private double? TryParse(String value) { double d; if ( Double.TryParse(value, out d) ) { return d; } return null; } /// <summary> /// Gets the feed at the specified URL. /// </summary> /// <param name="url">The URL.</param> /// <returns>A <see cref="SyndicationFeed"/> object.</returns> public static SyndicationFeed GetFeed(String url) { SyndicationFeed feed = null; try { log.Debug("Loading RSS feed: " + url); using ( var reader = XmlReader.Create(url) ) { feed = SyndicationFeed.Load(reader); } } catch ( Exception ex ) { log.Error("Error occurred while loading RSS feed: " + url, ex); } return feed; } } } The only method that will be generated in the client side proxy class, EarthquakeContext, will be the GetEarthquakes() method. The reason being that it is the only public instance method and it returns an IQueryable<Earthquake> collection that can be consumed by the client application. GetEarthquakes() calls the static GetFeed(String) method, which utilizes the built in SyndicationFeed API to load the external data feed. You will need to add a reference to the System.ServiceModel.Web library in order to take advantage of the RSS/Atom reader. The API will also allow you to create your own feeds to serve up in your applications. Model I have also created a Model folder and added a new class, Earthquake.cs. The Earthquake object will hold the various properties returned from the Atom feed. Here is a sample of the code for that class. Notice the [Key] attribute on the Id property, which is required by RIA Services to uniquely identify the entity. using System; using System.Collections.Generic; using System.Linq; using System.Runtime.Serialization; using System.ComponentModel.DataAnnotations; namespace EarthquakeLocator.Web.Model { /// <summary> /// Represents an earthquake occurrence and related information. /// </summary> [DataContract] public class Earthquake { /// <summary> /// Gets or sets the id. /// </summary> /// <value>The id.</value> [Key] [DataMember] public string Id { get; set; } /// <summary> /// Gets or sets the title. /// </summary> /// <value>The title.</value> [DataMember] public string Title { get; set; } /// <summary> /// Gets or sets the summary. /// </summary> /// <value>The summary.</value> [DataMember] public string Summary { get; set; } // additional properties omitted } } View Model The recent trend to use the MVVM pattern for WPF and Silverlight provides a great way to separate the data and behavior logic out of the user interface layer of your client applications. I have chosen to use the MVVM Light Toolkit for the Earthquake Locator, but there are other options out there if you prefer another library. That said, I went ahead and created a ViewModel folder in the Silverlight project and added a EarthquakeViewModel class that derives from ViewModelBase. Here is the code: using System; using System.Collections.ObjectModel; using System.ComponentModel.Composition; using System.ComponentModel.Composition.Hosting; using Microsoft.Maps.MapControl; using GalaSoft.MvvmLight; using EarthquakeLocator.Web.Model; using EarthquakeLocator.Web.Services; namespace EarthquakeLocator.ViewModel { /// <summary> /// Provides data for views displaying earthquake information. /// </summary> public class EarthquakeViewModel : ViewModelBase { [Import] public EarthquakeContext Context; /// <summary> /// Initializes a new instance of the <see cref="EarthquakeViewModel"/> class. /// </summary> public EarthquakeViewModel() { var catalog = new AssemblyCatalog(GetType().Assembly); var container = new CompositionContainer(catalog); container.ComposeParts(this); Initialize(); } /// <summary> /// Initializes a new instance of the <see cref="EarthquakeViewModel"/> class. /// </summary> /// <param name="context">The context.</param> public EarthquakeViewModel(EarthquakeContext context) { Context = context; Initialize(); } private void Initialize() { MapCenter = new Location(20, -170); ZoomLevel = 2; } #region Private Methods private void OnAutoLoadDataChanged() { LoadEarthquakes(); } private void LoadEarthquakes() { var query = Context.GetEarthquakesQuery(); Context.Earthquakes.Clear(); Context.Load(query, (op) => { if ( !op.HasError ) { foreach ( var item in op.Entities ) { Earthquakes.Add(item); } } }, null); } #endregion Private Methods #region Properties private bool autoLoadData; /// <summary> /// Gets or sets a value indicating whether to auto load data. /// </summary> /// <value><c>true</c> if auto loading data; otherwise, <c>false</c>.</value> public bool AutoLoadData { get { return autoLoadData; } set { if ( autoLoadData != value ) { autoLoadData = value; RaisePropertyChanged("AutoLoadData"); OnAutoLoadDataChanged(); } } } private ObservableCollection<Earthquake> earthquakes; /// <summary> /// Gets the collection of earthquakes to display. /// </summary> /// <value>The collection of earthquakes.</value> public ObservableCollection<Earthquake> Earthquakes { get { if ( earthquakes == null ) { earthquakes = new ObservableCollection<Earthquake>(); } return earthquakes; } } private Location mapCenter; /// <summary> /// Gets or sets the map center. /// </summary> /// <value>The map center.</value> public Location MapCenter { get { return mapCenter; } set { if ( mapCenter != value ) { mapCenter = value; RaisePropertyChanged("MapCenter"); } } } private double zoomLevel; /// <summary> /// Gets or sets the zoom level. /// </summary> /// <value>The zoom level.</value> public double ZoomLevel { get { return zoomLevel; } set { if ( zoomLevel != value ) { zoomLevel = value; RaisePropertyChanged("ZoomLevel"); } } } #endregion Properties } } The EarthquakeViewModel class contains all of the properties that will be bound to by the various controls in our views. Be sure to read through the LoadEarthquakes() method, which handles calling the GetEarthquakes() method in our EarthquakeService via the EarthquakeContext proxy, and also transfers the loaded entities into the view model’s Earthquakes collection. Another thing to notice is what’s going on in the default constructor. I chose to use the Managed Extensibility Framework (MEF) for my composition needs, but you can use any dependency injection library or none at all. To allow the EarthquakeContext class to be discoverable by MEF, I added the following partial class so that I could supply the appropriate [Export] attribute: using System; using System.ComponentModel.Composition; namespace EarthquakeLocator.Web.Services { /// <summary> /// The client side proxy for the EarthquakeService class. /// </summary> [Export] public partial class EarthquakeContext { } } One last piece I wanted to point out before moving on to the user interface, I added a client side partial class for the Earthquake entity that contains helper properties that we will bind to later: using System; namespace EarthquakeLocator.Web.Model { /// <summary> /// Represents an earthquake occurrence and related information. /// </summary> public partial class Earthquake { /// <summary> /// Gets the location based on the current Latitude/Longitude. /// </summary> /// <value>The location.</value> public string Location { get { return String.Format("{0},{1}", Latitude, Longitude); } } /// <summary> /// Gets the size based on the Magnitude. /// </summary> /// <value>The size.</value> public double Size { get { return (Magnitude * 3); } } } } View Now the fun part! Usually, I would create a Views folder to place all of my View controls in, but I took the easy way out and added the following XAML code to the default MainPage.xaml file. Be sure to add the bing prefix associating the Microsoft.Maps.MapControl namespace after adding the assembly reference to your project. The MVVM Light Toolkit project templates come with a ViewModelLocator class that you can use via a static resource, but I am instantiating the EarthquakeViewModel directly in my user control. I am setting the AutoLoadData property to true as a way to trigger the LoadEarthquakes() method call. The MapItemsControl found within the <bing:Map> control binds its ItemsSource property to the Earthquakes collection of the view model, and since it is an ObservableCollection<T>, we get the automatic two way data binding via the INotifyCollectionChanged interface. <UserControl x:Class="EarthquakeLocator.MainPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:bing="clr-namespace:Microsoft.Maps.MapControl;assembly=Microsoft.Maps.MapControl" xmlns:vm="clr-namespace:EarthquakeLocator.ViewModel" mc:Ignorable="d" d:DesignWidth="640" d:DesignHeight="480" > <UserControl.Resources> <DataTemplate x:Key="EarthquakeTemplate"> <Ellipse Fill="Red" Stroke="Black" StrokeThickness="1" Width="{Binding Size}" Height="{Binding Size}" bing:MapLayer.Position="{Binding Location}" bing:MapLayer.PositionOrigin="Center"> <ToolTipService.ToolTip> <StackPanel> <TextBlock Text="{Binding Title}" FontSize="14" FontWeight="Bold" /> <TextBlock Text="{Binding UtcTime}" /> <TextBlock Text="{Binding LocalTime}" /> <TextBlock Text="{Binding DepthDesc}" /> </StackPanel> </ToolTipService.ToolTip> </Ellipse> </DataTemplate> </UserControl.Resources> <UserControl.DataContext> <vm:EarthquakeViewModel AutoLoadData="True" /> </UserControl.DataContext> <Grid x:Name="LayoutRoot"> <bing:Map x:Name="map" CredentialsProvider="--Your-Bing-Maps-Key--" Center="{Binding MapCenter, Mode=TwoWay}" ZoomLevel="{Binding ZoomLevel, Mode=TwoWay}"> <bing:MapItemsControl ItemsSource="{Binding Earthquakes}" ItemTemplate="{StaticResource EarthquakeTemplate}" /> </bing:Map> </Grid> </UserControl> The EarthquakeTemplate defines the Ellipse that will represent each earthquake, the Width and Height that are determined by the Magnitude, the Position on the map, and also the tooltip that will appear when we mouse over each data point. Running the application will give us the following result (shown with a tooltip example): That concludes this portion of our show but I plan on implementing additional functionality in later blog posts.

Java word scramble game [closed]

- by Dan

I'm working on code for a word scramble game in Java. I know the code itself is full of bugs right now, but my main focus is getting a vector of strings broken into two separate vectors containing hints and words. The text file that the strings are taken from has a colon separating them. So here is what I have so far. public WordApp() { inputRow = new TextInputBox(); inputRow.setLocation(200,100); phrases = new Vector <String>(FileUtilities.getStrings()); v_hints = new Vector<String>(); v_words = new Vector<String>(); textBox = new TextBox(200,100); textBox.setLocation(200,200); textBox.setText(scrambled + "\n\n Time Left: \t" + seconds/10 + "\n Score: \t" + score); hintBox = new TextBox(200,200); hintBox.setLocation(300,400); hintBox.hide(); Iterator <String> categorize = phrases.iterator(); while(categorize.hasNext()) { int index = phrases.indexOf(":"); String element = categorize.next(); v_words.add(element.substring(0,index)); v_hints.add(element.substring(index +1)); phrases.remove(index); System.out.print(index); } The FileUtilities file was given to us by the pofessor, here it is. import java.util.*; import java.io.*; public class FileUtilities { private static final String FILE_NAME = "javawords.txt"; //------------------ getStrings ------------------------- // // returns a Vector of Strings // Each string is of the form: word:hint // where word contains no spaces. // The words and hints are read from FILE_NAME // // public static Vector<String> getStrings ( ) { Vector<String> words = new Vector<String>(); File file = new File( FILE_NAME ); Scanner scanFile; try { scanFile = new Scanner( file); } catch ( IOException e) { System.err.println( "LineInput Error: " + e.getMessage() ); return null; } while ( scanFile.hasNextLine() ) { // read the word and follow it by a colon String s = scanFile.nextLine().trim().toUpperCase() + ":"; if( s.length()>1 && scanFile.hasNextLine() ) { // append the hint and add to collection s+= scanFile.nextLine().trim(); words.add(s); } } // shuffle Collections.shuffle(words); return words; } }

Can't change color of sprites in unity

- by Aceleeon

I would like to create a script that targets a 2d sprite "enemy" and changes their color to red (slightly opaque red if possible) when you hit tab. I have this code from a 3d tutorial hoping the transition would work. But it does not. I only get the script to cycle the enemy tags but never changes the color of the sprite. I have the code below I'm very new to coding, and any help would be FANTASTIC! HELP! hahah. TL;DR Cant get 3d color targeting to work for 2D. Check out the c#code below using UnityEngine; using System.Collections; using System.Collections.Generic; public class Targetting : MonoBehaviour { public List targets; public Transform selectedTarget; private Transform myTransform; // Use this for initialization void Start () { targets = new List(); selectedTarget = null; myTransform = transform; AddAllEnemies(); } public void AddAllEnemies() { GameObject[] go = GameObject.FindGameObjectsWithTag("Enemy"); foreach(GameObject enemy in go) AddTarget(enemy.transform); } public void AddTarget(Transform enemy) { targets.Add(enemy); } private void SortTargetsByDistance() { targets.Sort(delegate(Transform t1,Transform t2) { return Vector3.Distance(t1.position, myTransform.position).CompareTo(Vector3.Distance(t2.position, myTransform.position)); }); } private void TargetEnemy() { if(selectedTarget == null) { SortTargetsByDistance(); selectedTarget = targets[0]; } else { int index = targets.IndexOf(selectedTarget); if(index < targets.Count -1) { index++; } else { index = 0; } selectedTarget = targets[index]; } } private void SelectTarget() { selectedTarget.GetComponent().color = Color.red; } private void DeselectTarget() { selectedTarget.GetComponent().color = Color.blue; selectedTarget = null; } // Update is called once per frame void Update() { if(Input.GetKeyDown(KeyCode.Tab)) { TargetEnemy(); } } }

[EF + Oracle] Inserting Data (Sequences) (2/2)

- by JTorrecilla

Prologue In the previous chapter we have see how to create DB records with EF, now we are going to Some Questions about Oracle. ORACLE One characteristic from SQL Server that differs from Oracle is “Identity”. To all that has not worked with SQL Server, this property, that applies to Integer Columns, lets indicate that there is auto increment columns, by that way it will be filled automatically, without writing it on the insert statement. In EF with SQL Server, the properties whose match with Identity columns, will be filled after invoking SaveChanges method. In Oracle DB, there is no Identity Property, but there is something similar. Sequences Sequences are DB objects, that allow to create auto increment, but there are not related directly to a Table. The syntax is as follows: name, min value, max value and begin value. 1: CREATE SEQUENCE nombre_secuencia 2: INCREMENT BY numero_incremento 3: START WITH numero_por_el_que_empezara 4: MAXVALUE valor_maximo | NOMAXVALUE 5: MINVALUE valor_minimo | NOMINVALUE 6: CYCLE | NOCYCLE 7: ORDER | NOORDER 8: How to get sequence value? To obtain the next val from the sequence: 1: SELECT nb_secuencia.Nextval 2: From Dual Due to there is no direct way to indicate that a column is related to a sequence, there is several ways to imitate the behavior: Use a Trigger (DB), Use Stored Procedures or Functions(…) or my particularly option. EF model, only, imports Table Objects, Stored Procedures or Functions, but not sequences. By that, I decide to create my own extension Method to invoke Next Val from a sequence: 1: public static class EFSequence 2: { 3: public static int GetNextValue(this ObjectContext contexto, string SequenceName) 4: { 5: string Connection = ConfigurationManager.ConnectionStrings["JTorrecillaEntities2"].ConnectionString; 6: Connection=Connection.Substring(Connection.IndexOf(@"connection string=")+19); 7: Connection = Connection.Remove(Connection.Length - 1, 1); 8: using (IDbConnection con = new Oracle.DataAccess.Client.OracleConnection(Connection)) 9: { 10: using (IDbCommand cmd = con.CreateCommand()) 11: { 12: con.Open(); 13: cmd.CommandText = String.Format("Select {0}.nextval from DUAL", SequenceName); 14: return Convert.ToInt32(cmd.ExecuteScalar()); 15: } 16: } 17: 18: } 19: } This Object Context’s extension method are going to invoke a query with the Sequence indicated by parameter. It takes the connection strings from the App settings, removing the meta data, that was created by VS when generated the EF model. And then, returns the next value from the Sequence. The next value of a Sequence is unique, by that, when some concurrent users are going to create records in the DB using the sequence will not get duplicates. This is my own implementation, I know that it could be several ways to do and better ways. If I find any other way, I promise to post it. To use the example is needed to add a reference to the Oracle (ODP.NET) dll.

Allow opening a new tab with Ctrl+T on all websites in Firefox

- by Martin J.H.

In Firefox, certain websites and plugins (Adobe PDF Plugin) appear to "capture" the Control key, so that when I try to open a new tab using "Ctrl+t", nothing happens - or worse, something unexpected happens. Examples: On the Codecademy site, while editing code, Ctrl+T either does nothing, or (when Flash is disabled) switches the position of the two characters next to the cursor. When viewing PDF's with the Adobe PDF Plugin, Ctrl+T does nothing. Is there a way to disable this "feature"? I would like "Ctrl+t" to always "talk" to Firefox! Edit: After searching superuser deeper, this question is very similar to the questions: "How to prevent keystroke grabbing/hijacking by websites in Firefox?" "How do I prevent pages I visit from overriding selected Firefox shortcut keys?". The answers to these questions are interesting and relevant, but do not give a method on how to disable combinatinos such as "Ctrl+t". Maybe a modified Greasemonkey script is the easiest solultion. Edit 2 - Attempt at a solution The following UserScript (Use GreaseMonkey to install it) successfully captures Ctrl+t on some sites (Google Search site, for instance - PopUp "Gotcha" appears), but not on the Codecademy site. I found another question pertaining to this subject here: "How to forbid keyboard shortcut stealing by websites in Firefox". It was raised in 2010, and the consensus was: It can't be done. // ==UserScript== // @name Disable Ctrl T interceptions // @description Stop websites from highjacking keyboard shortcuts // // @run-at document-start // @include * // @grant none // ==/UserScript== // Keycode for 't'. Add more to disable other ctrl+X interceptions keycodes = [84]; var lastPressedButton = [0]; document.addEventListener('keydown', function(e) { //uncomment to find out the keycode for any given key // alert(e.keyCode ); if (keycodes.indexOf(e.keyCode) != -1 && e.ctrlKey) { e.cancelBubble = true; e.stopImmediatePropagation(); alert("Gotcha!"); } return false; });

How to take search query and append modifers to the end of it

- by Kimber

This is a greasemonkey question. What I'm trying to do is modify an old google discussions script. What were wanting to do is be able to take the google search query and add modifiers to the end of it. Like this: search query: "superuser" modifiers: inurl:greasemonkey+question end result: "superuser" inurl:greasemonkey+question The old script creates a new div within the "hdtb_more_mn" element which is where you get the new discussions tab. However, since the "tbm=dsc" option to do a discussion search has died, this script no longer works. Hence the need to add modifiers to your searches. I tried to edit the script, but it appends the modifiers to the end of the url which includes "&client=firefox-a&hs=8uS&rls=org.mozilla:en-US:official". This means you're also searching for the above as well as your query, which doesn't work. I would like to be able to append the modifiers @ the end of the search querty, rather than the whole URL. I'm just not sure how to code it to where it adds the below "&tbm=" stuff within "discussionDiv.innerHTML" to the end of the query. The google search id seems to be, "gbqfq" for the search box, but I'm not sure how to add this id. Here is the old script // ==UserScript== // @name Add Back Google Discussions // @version 1.4 // @description Adds back the Discussion filters to Google Search // @include *://*.google.tld/search* // ==/UserScript== var url = location.href; if (url.indexOf('tbm=dsc') < 0) addFilterType('dsc', 'Discussions'); function addFilterType(val, name) { var searchType = document.getElementById('hdtb_more_mn'); var discussionDiv = document.createElement('DIV'); discussionDiv.className = 'hdtb_mitem'; discussionDiv.innerHTML = '<a class="q qs" href="'+ (url.replace(/&tbm=[^&]*/g,'') + '&tbm=' + val) +'">'+name+'</a>'; searchType.innerHTML += discussionDiv.outerHTML; } Thanks for any help, or suggestions on who to ask. Google Chrome has an extension for discussion searches, but FF doesn't seem to have one as of yet, which is why I'm trying to modify the above.

Dojo - How to position tooltip close to text?

- by user244394

Like the title says i want to be able to display the tooltip close to the text, currently it is displayed far away in the cell. Tobe noted the tooltip positions correctly for large text, only fails for small text. In DOJO How can i position the tooltip close to the text? I have this bit of code snippet that display the tooltip in the grid cells.

Unexpected ArrayIndexOutOfBoundsException in JavaFX application, refering to no array

I have the following code: public void setContent(Importer3D importer) { if (DEBUG) { System.out.println("Initialization of Mesh's arrays"); } coords = importer.getCoords(); texCoords = importer.getTexCoords(); faces = importer.getFaces(); if (DEBUG) { System.out.println("Applying Mesh's arrays"); } mesh = new TriangleMesh(); mesh.getPoints().setAll(coords); mesh.getTexCoords().setAll(texCoords); mesh.getFaces().setAll(faces); if (DEBUG) { System.out.println("Initialization of the material"); } initMaterial(); if (DEBUG) { System.out.println("Setting the MeshView"); } meshView.setMesh(mesh); meshView.setMaterial(material); meshView.setDrawMode(DrawMode.FILL); if (DEBUG) { System.out.println("Adding to 3D scene"); } root3d.getChildren().clear(); root3d.getChildren().add(meshView); if (DEBUG) { System.out.println("3D model is ready!"); } } The Imporeter3D class part: private void load(File file) { stlLoader = new STLLoader(file); } public float[] getCoords() { return stlLoader.getCoords(); } public float[] getTexCoords() { return stlLoader.getTexCoords(); } public int[] getFaces() { return stlLoader.getFaces(); } The STLLoader: public class STLLoader{ public STLLoader(File file) { stlFile = new STLFile(file); loadManager = stlFile.loadManager; pointsArray = new PointsArray(stlFile); texCoordsArray = new TexCoordsArray(); } public float[] getCoords() { return pointsArray.getPoints(); } public float[] getTexCoords() { return texCoordsArray.getTexCoords(); } public int[] getFaces() { return pointsArray.getFaces(); } private STLFile stlFile; private PointsArray pointsArray; private TexCoordsArray texCoordsArray; private FacesArray facesArray; public SimpleBooleanProperty finished = new SimpleBooleanProperty(false); public LoadManager loadManager;} PointsArray file: public class PointsArray { public PointsArray(STLFile stlFile) { this.stlFile = stlFile; initPoints(); } private void initPoints() { ArrayList<Double> pointsList = stlFile.getPoints(); ArrayList<Double> uPointsList = new ArrayList<>(); faces = new int[pointsList.size()*2]; int n = 0; for (Double d : pointsList) { if (uPointsList.indexOf(d) == -1) { uPointsList.add(d); } faces[n] = uPointsList.indexOf(d); faces[++n] = 0; n++; } int i = 0; points = new float[uPointsList.size()]; for (Double d : uPointsList) { points[i] = d.floatValue(); i++; } } public float[] getPoints() { return points; } public int[] getFaces() { return faces; } private float[] points; private int[] faces; private STLFile stlFile; public static boolean DEBUG = true; } And STLFile: ArrayList<Double> coords = new ArrayList<>(); double temp; private void readV(STLParser parser) { for (int n = 0; n < 3; n++) { if(!(parser.ttype==STLParser.TT_WORD && parser.sval.equals("vertex"))) { System.err.println("Format Error:expecting 'vertex' on line " + parser.lineno()); } else { if (parser.getNumber()) { temp = parser.nval; coords.add(temp); if(DEBUG) { System.out.println("Vertex:"); System.out.print("X=" + temp + " "); } if (parser.getNumber()) { temp = parser.nval; coords.add(temp); if(DEBUG) { System.out.print("Y=" + temp + " "); } if (parser.getNumber()) { temp = parser.nval; coords.add(temp); if(DEBUG) { System.out.println("Z=" + temp + " "); } readEOL(parser); } else System.err.println("Format Error: expecting coordinate on line " + parser.lineno()); } else System.err.println("Format Error: expecting coordinate on line " + parser.lineno()); } else System.err.println("Format Error: expecting coordinate on line " + parser.lineno()); } if (n < 2) { try { parser.nextToken(); } catch (IOException e) { System.err.println("IO Error on line " + parser.lineno() + ": " + e.getMessage()); } } } } public ArrayList<Double> getPoints() { return coords; } As a result of all of this code, I expected to get 3d model in MeshView.

Problems with with A* algorithm

- by V_Programmer

I'm trying to implement the A* algorithm in Java. I followed this tutorial,in particular, this pseudocode: http://theory.stanford.edu/~amitp/GameProgramming/ImplementationNotes.html The problem is my code doesn't work. It goes into an infinite loop. I really don't know why this happens... I suspect that the problem are in F = G + H function implemented in Graph constructors. I suspect I am not calculate the neighbor F correclty. Here's my code: List<Graph> open; List<Graph> close; private void createRouteAStar(Unit u) { open = new ArrayList<Graph>(); close = new ArrayList<Graph>(); u.ai_route_endX = 11; u.ai_route_endY = 5; List<Graph> neigh; int index; int i; boolean finish = false; Graph current; int cost; Graph start = new Graph(u.xMap, u.yMap, 0, ManhattanDistance(u.xMap, u.yMap, u.ai_route_endX, u.ai_route_endY)); open.add(start); current = start; while(!finish) { index = findLowerF(); current = new Graph(open, index); System.out.println(current.x); System.out.println(current.y); if (current.x == u.ai_route_endX && current.y == u.ai_route_endY) { finish = true; } else { close.add(current); neigh = current.getNeighbors(); for (i = 0; i < neigh.size(); i++) { cost = current.g + ManhattanDistance(current.x, current.y, neigh.get(i).x, neigh.get(i).y); if (open.contains(neigh.get(i)) && cost < neigh.get(i).g) { open.remove(open.indexOf(neigh)); } else if (close.contains(neigh.get(i)) && cost < neigh.get(i).g) { close.remove(close.indexOf(neigh)); } else if (!open.contains(neigh.get(i)) && !close.contains(neigh.get(i))) { neigh.get(i).g = cost; neigh.get(i).f = cost + ManhattanDistance(neigh.get(i).x, neigh.get(i).y, u.ai_route_endX, u.ai_route_endY); neigh.get(i).setParent(current); open.add(neigh.get(i)); } } } } System.out.println("step"); for (i=0; i < close.size(); i++) { if (close.get(i).parent != null) { System.out.println(i); System.out.println(close.get(i).parent.x); System.out.println(close.get(i).parent.y); } } } private int findLowerF() { int i; int min = 10000; int minIndex = -1; for (i=0; i < open.size(); i++) { if (open.get(i).f < min) { min = open.get(i).f; minIndex = i; System.out.println("min"); System.out.println(min); } } return minIndex; } private int ManhattanDistance(int ax, int ay, int bx, int by) { return Math.abs(ax-bx) + Math.abs(ay-by); } And, as I've said. I suspect that the Graph class has the main problem. However I've not been able to detect and fix it. public class Graph { int x, y; int f,g,h; Graph parent; public Graph(int x, int y, int g, int h) { this.x = x; this.y = y; this.g = g; this.h = h; this.f = g + h; } public Graph(List<Graph> list, int index) { this.x = list.get(index).x; this.y = list.get(index).y; this.g = list.get(index).g; this.h = list.get(index).h; this.f = list.get(index).f; this.parent = list.get(index).parent; } public Graph(Graph gp) { this.x = gp.x; this.y = gp.y; this.g = gp.g; this.h = gp.h; this.f = gp.f; } public Graph(Graph gp, Graph parent) { this.x = gp.x; this.y = gp.y; this.g = gp.g; this.h = gp.h; this.f = g + h; this.parent = parent; } public List<Graph> getNeighbors() { List<Graph> aux = new ArrayList<Graph>(); aux.add(new Graph(x+1, y, g,h)); aux.add(new Graph(x-1, y, g,h)); aux.add(new Graph(x, y+1, g,h)); aux.add(new Graph(x, y-1, g,h)); return aux; } public void setParent(Graph g) { parent = g; } } Little Edit: Using the System.out and the Debugger I discovered that the program ALWAYS is check the same "current" graph, (15,8) which is the (u.xMap, u.yMap) position. Looks like it keeps forever in the first step.

Commit in sharpSVN

- by Pedro

Hello! I have a problem doing commit with sharpsvn. Now i´m adding all the files of my working copy (if the file is added throws an exception), and after it i do commit. It works but it trows exceptions. There is some way to get the status of the repository before do add() and only add the new files or the files who are changed? And if i delete one file or folder on my working copy , How can i delete these files or folder on the repository? Code: String[] folders; folders = Directory.GetDirectories(direccionLocal,"*.*", SearchOption.AllDirectories); foreach (String folder in folders) { String[] files; files = Directory.GetFiles(folder); foreach (String file in files) { if (file.IndexOf("\\.svn") == -1) { Add(file, workingcopy); } } } Commit(workingcopy, "change"); Add: public bool Add(string path, string direccionlocal) { using (SvnClient client = new SvnClient()) { SvnAddArgs args = new SvnAddArgs(); args.Depth = SvnDepth.Empty; Console.Out.WriteLine(path); args.AddParents = true; try { return client.Add(path, args); } catch (Exception ex) { return false; } } } Commit: public bool Commit(string path, string message) { using (SvnClient client = new SvnClient()) { SvnCommitArgs args = new SvnCommitArgs(); args.LogMessage = message; args.ThrowOnError = true; args.ThrowOnCancel = true; try { return client.Commit(path, args); } catch (Exception e) { if (e.InnerException != null) { throw new Exception(e.InnerException.Message, e); } throw e; } } }

jQuery attribute selector inside a jQuery object

- by chifliiiii

Im trying to set up a quicksand with multiple filters and the approach im taking in the following which im not sure if its the best. $filteredItems = $containerClone.find('.portfolio-item-marketing').filter(function(index){ if ( $filterA != 'all' && $filterB != 'all' ) { return jQuery(this).find('.portfolio-item-marketing[data-type~=' + $filterA + ']') || jQuery(this).find('.portfolio-item-marketing[data-type~=' + $filterB + ']'); } if ( $filterA != 'all' && $filterB == 'all' ) { return jQuery(this+'[data-type~='+$filterA+']') ; } if ( $filterA == 'all' && $filterB != 'all' ) { return jQuery(this).find('.portfolio-item-marketing[data-type~=' + $filterB + ']'); } if ( $filterA == 'all' && $filterB == 'all' ) { return jQuery(this).find('.portfolio-item-marketing'); } }); As you see in the code i tried 2 different methods ( First "if" and second "if" ). Im not sure if i can use find inside a filter but i also dont know how to get the attribute from the jQuery object. I can not use jQuery(this).attr('data-type') == $filterA Because the attribute maybe contain various filters .Thats why im trying to use jQuery "~=" Should i give up and end using a indexOf ?

codingbat wordEnds using regex

- by polygenelubricants

I'm trying to solve wordEnds from codingbat.com using regex. This is the simplest as I can make it with my current knowledge of regex: public String wordEnds(String str, String word) { return str.replaceAll( String.format( ".*?(?=%s)(?<=(.|^))%1$s(?=(.|$))|.+", java.util.regex.Pattern.quote(word) ), "$1$2" ); } String.format is used to inject word into the pattern for both readability and convenience (it's injected twice). Pattern.quote isn't necessary to pass their tests, but I think it's required for a proper regex-based solution. The regex has two major parts: If after matching as few characters as possible ".*?", word can still be found "(?=%s)", then lookbehind to capture any character immediately preceding it "(?<=(.|^))", match word "%1$s" and lookforward to capture any character following it "(?=(.|$))". The initial "if" test ensures that the atomic lookbehind captures only if there's a word Using lookahead to capture the following character doesn't consume it, so it can be used as part of further matching Otherwise match what's left "|.+" Groups 1 and 2 would capture empty strings I think this works in all cases, but it's obviously quite complex. I'm just wondering if others can suggest a simpler regex to do this. Note: I'm not looking for a solution using indexOf and a loop. I want a regex-based replaceAll solution. I also need a working solution that I can just copy-paste into codingbat and passes.

Postback problem when using URL Rewrite and 404.aspx

- by salle55

I'm using URL rewrite on my site to get URLs like: http://mysite.com/users/john instead of http://mysite.com/index.aspx?user=john To achive this extensionless rewrite with IIS6 and no access to the hosting-server I use the "404-approach". When a request that the server can't find, the mapped 404-page is executed, since this is a aspx-page the rewrite can be performed (I can setup the 404-mapping using the controlpanel on the hosting-service). This is the code in Global.asax: protected void Application_BeginRequest(object sender, EventArgs e) { string url = HttpContext.Current.Request.Url.AbsolutePath; if (url.Contains("404.aspx")) { string[] urlInfo404 = Request.Url.Query.ToString().Split(';'); if (urlInfo404.Length > 1) { string requestURL = urlInfo404[1]; if (requestURL.Contains("/users/")) { HttpContext.Current.RewritePath("~/index.aspx?user=" + GetPageID(requestURL)); StoreRequestURL(requestURL); } else if (requestURL.Contains("/picture/")) { HttpContext.Current.RewritePath("~/showPicture.aspx?pictureID=" + GetPageID(requestURL)); StoreRequestURL(requestURL); } } } } private void StoreRequestURL(string url) { url = url.Replace("http://", ""); url = url.Substring(url.IndexOf("/")); HttpContext.Current.Items["VirtualUrl"] = url; } private string GetPageID(string requestURL) { int idx = requestURL.LastIndexOf("/"); string id = requestURL.Substring(idx + 1); id = id.Replace(".aspx", ""); //Only needed when testing without the 404-approach return id; } And in Page_Load on my masterpage I set the correct URL in the action-attribute on the form-tag. protected void Page_Load(object sender, EventArgs e) { string virtualURL = (string)HttpContext.Current.Items["VirtualUrl"]; if (!String.IsNullOrEmpty(virtualURL)) { form1.Action = virtualURL; } } The rewrite works fine but when I perform a postback on the page the postback isn't executed, can this be solved somehow? The problem seems to be with the 404-approach because when I try without it (and loses the extensionless-feature) the postback works. That is when I request: http://mysite.com/users/john.aspx Can this be solved or is there any other solution that fulfil my requirements (IIS6, no serveraccess/ISAPI-filter and extensionless).

How to use the buffer on SocketAsyncEventArgs object

- by Rob

We're stuck with using buffers on the SocketAsyncEventArgs object. With the old socket method we'd cast our state object, like this: clientState cs = (clientState)asyncResult.AsyncState; However, the 3.5 framework is different. With have strings arriving from the client in chunks and we can't seem to work out how the buffers work so we can process an entire string when we find a char3. Code at the moment: private void ProcessReceive(SocketAsyncEventArgs e) { string content = string.Empty; // Check if the remote host closed the connection. if (e.BytesTransferred > 0) { if (e.SocketError == SocketError.Success) { Socket s = e.UserToken as Socket; //asyncResult.AsyncState; Int32 bytesTransferred = e.BytesTransferred; // Get the message received from the listener. content += Encoding.ASCII.GetString(e.Buffer, e.Offset, bytesTransferred); if (content.IndexOf(Convert.ToString((char)3)) > -1) { e.BufferList = null; // Increment the count of the total bytes receive by the server. Interlocked.Add(ref this.totalBytesRead, bytesTransferred); } else { content += Encoding.ASCII.GetString(e.Buffer, e.Offset, bytesTransferred); ProcessReceive(e); } } else { this.CloseClientSocket(e); } } }

ASP.NET Session State Timeout Problem

- by user314827

I am trying to detect a session state timeout in my asp.net application and am unable to do so. I have a base class that derives from System.Web.UI.Page as follows:- public class BasePageSessionExpire : Page { override protected void OnInit(EventArgs e) { base.OnInit(e); if (Context.Session != null) { if (Session.IsNewSession) { string szCookieHeader = Request.Headers["Cookie"]; if ((null != szCookieHeader) && (szCookieHeader.IndexOf("ASP.NET_SessionId") > 0)) { Session.Abandon(); Response.Redirect("~/SessionExpired.aspx",true); } } } } } All the pages I need session state checking on derive from this base class instead of "System.Web.UI.Page". Also, all these pages have EnableSessionState="True". I have a blank Session_Start() method in my global.asax file if that is relevant at all. For some reason after the first request, the "Session.IsNewSession" property is always false. It is true only for the first request and then is always false. I have my timeout set to 1 minute. The session never seems to timeout. What am I missing here ? Thanks in advance.

Help with an AJAX request

- by sea_1987

The Problem I am tring to do an ajax request to a PHP script, however I am having a problem getting the data into the format that the PHP is expecting it, the PHP is expecting the data to come in as array within an array something like, Array ( [cv_file] => Array ( [849649717] => Y [849649810] => Y ) [save] => Save CVs ) What have I tried? I have tried in my javascript to create an empty array and use that as the array key, something like this, var cv_file = new Array(); $(".drag_check").draggable({helper:"clone", opacity:"0.5"}); $(".searchPage").droppable({ accept:".drag_check", hoverClass: "dropHover", drop: function(ev, ui) { var droppedItem = ui.draggable.children(); cv_file = ui.draggable.children().attr('name'); var link = ui.draggable.children().attr('name').substr(ui.draggable.children().attr('name').indexOf("[")+1, ui.draggable.children().attr('name').lastIndexOf("]")-8) $.ajax({ type:"POST", url:"/search", data:cv_file+"&save=Save CVs", success:function(){ alert(cv_file) $('.shortList').append('<li><input type="checkbox" value="Y" class="checkbox" name="remove_cv['+link+']"/><a href="/cv/'+link+'">'+link+'</a></li>'); }, error:function() { alert("Somthing has gone wrong"); } }); } }); My Question How can I get the data into the format that the PHP is expecting, I would appreciate any help that anyone can give? Edit On alerting what the poster in the comments suggested I get he following, cv_file[849649717]&save=Save CVs Thank you

How to sort linq result by most similarity/equality

- by aNui

I want to do a search for Music instruments which has its informations Name, Category and Origin as I asked in my post. But now I want to sort/group the result by similarity/equality to the keyword such as. If I have the list { Drum, Grand Piano, Guitar, Guitarrón, Harp, Piano} << sorted by name and if I queried "p" the result should be { Piano, Grand Piano, Harp } but it shows Harp first because of the source list's sequence and if I add {Grand Piano} to the list and query "piano" the result shoud be like { Piano, Grand Piano } or query "guitar" it should be { Guitar, Guitarrón } here's my code static IEnumerable<MInstrument> InstrumentsSearch(IEnumerable<MInstrument> InstrumentsList, string query, MInstrument.Category[] SelectedCategories, MInstrument.Origin[] SelectedOrigins) { var result = InstrumentsList .Where(item => SelectedCategories.Contains(item.category)) .Where(item => SelectedOrigins.Contains(item.origin)) .Where(item => { if ( (" " + item.Name.ToLower()).Contains(" " + query.ToLower()) || item.Name.IndexOf(query) != -1 ) { return true; } return false; } ) .Take(30); return result.ToList<MInstrument>(); } Or the result may be like my old self-invented algorithm that I called "by order of occurence", that is just OK to me. And the further things to do is I need to search the Name, Category or Origin such as. If i type "Italy" it should found Piano or something from Italy. Or if I type "string" it should found Guitar. Is there any way to do those things, please tell me. Thanks in advance.

Problem in IE8 with GET Parameters in opening a new windows with javascript.

- by amfa95

Hi, I have a problem with IE8 and the opening of a new window with javascript and submitting parameters with special characters. <a href="javascript:oWin('/html/de/4664286/printregistrationcontent.html?12-security question=Wie heißt Ihr Lieblingsrestaurant','PRINT',800,600);" class="print">Seite drucken</a> The Problem is the letter 'ß' (sharp S). As you can see the string above is encodes due to anti XSS. This link works in FF and IE6 but IE8 is transmitting the URL Parameter as character with code 65*** (don't know the exaxt value). In the opening window you will only see a square (because character with 65000+ is not printable). I also tried to use URL Encoding instead of HTML encoding <a href="javascript:oWin('/html/de/4664286/printregistrationcontent.html?12-security question%3DWie hei%C3%9Ft Ihr Lieblingsrestaurant','PRINT',800,600);" class="print">Seite drucken</a> If i click on this Link in FF or IE6 it works as expected, but IE8 will fail to transmit the "ß" to the server and therefor will also get it back in the wrong way. If i paste this url to the IE8 it will work too, but not if the window is opened by javascript. The Javascript function oWin is defined as follows function oWin(url,title,sizeH,sizeV) { winHandle = top.open(url,title,'toolbar=no,directories=no,status=yes,scrollbars=yes,menubar=no,resizable=no,width='+sizeH+',height='+sizeV); if(navigator.appVersion.indexOf("MSIE 3",0)==-1) id = setTimeout('winHandle.focus()',1000); } If someone has an idea where to look for the reason please answer to this. Thank you amfa

CSharpCodeProvider 'cannot find metadata file' Compiling Plugin Code With Mono

- by Jason Champion

I have some code in an XML file that I load and compile at runtime in an application. This works fine on Windows, but under Mono I get assembly reference errors. Here's the examine code in question: public static bool CompileSpell(Spell spell) { CSharpCodeProvider prov = new CSharpCodeProvider(); CompilerParameters cp = new CompilerParameters(); cp.GenerateExecutable = true; cp.GenerateInMemory = true; cp.ReferencedAssemblies.Add("system.dll"); cp.ReferencedAssemblies.Add("system.xml.dll"); cp.ReferencedAssemblies.Add("BasternaeMud.dll"); cp.ReferencedAssemblies.Add("ZoneData.dll"); Log.Trace("Compiling spell '" + spell.Name + "'."); StringBuilder sb = new StringBuilder(); int idx = spell.FileName.IndexOf('.'); string file = spell.FileName; if (idx > 0) { file = spell.FileName.Substring(0, idx); } int lines = GenerateWithMain(sb, spell.Code, "BasternaeMud"); CompilerResults cr = prov.CompileAssemblyFromSource(cp,sb.ToString()); .... The specific errors I get in the compiler results are: cannot find metadata file 'system.dll' at line 0 column 0. cannot find metadata file 'system.xml.dll' at line 0 column 0. Mono obviously doesn't like the way I add referenced assemblies to the code I'm compiling for system.xml and system.xml.dll. The other two assemblies add fine, which is no surprise because they're the code that the compiler is actually executing from and exist in the executable directory. Any clue what I need to do to fix this? Maybe I could just drop those DLLs in the executable directory, but that feels like a dumb idea.
