  • Storing User Information in Session with aspNetMembershipProvider

    - by Muhammad Adeel Zahid
    Hi Everyone, i m developing an application in .NET mvc2. i m using aspnetMembershipProvider for User registration and related activities. i need some custom information about user that i stored in a separate table (sysUser for example) and linked it to aspnetUser table through foreign key. after Login i need to fetch user's credentials from sysUser table and push it to the session. For this Account controller's Logon method seemed best to me and i pasted following code in my Logon ActionResult if (!ValidateLogOn(userName, password)) { return View(); } FormsAuth.SignIn(userName, rememberMe); ApplicationRepository _ApplicationRepository = new ApplicationRepository(); MembershipUser aspUser = Membership.GetUser(userName); SessionUser CurrentUser = _ApplicationRepository.GetUserCredentials(aspUser.ProviderUserKey.ToString()); //Session["CurrentUser"] = CurrentUser; if (!String.IsNullOrEmpty(returnUrl)) { return Redirect(returnUrl); } else { return RedirectToAction("Index", "Home"); } The code is working perfectly for me and put my desired information in the session but the thing is that if a user selects Remember me and on his next visit he won't have to Log in and i would not find my desired information in the Session. Can anyone guide me where should i put my code that stores the user information in the session. any Help is Highly appreciated Regards Adeel

  • Pinyin Character entry on a touchscreen keyboard

    - by mmr
    The app I'm developing requires that it be deployed in China, which means that it needs to have Pinyin and Chinese character handling. I'm told that the way that our customers handle character entry is like so: Enter in the pinyin character, like 'zhang' As they enter the characters, a list of possible Chinese (Mandarin?) characters are presented to the user, like: The user will then select '1' to enter the family name that is roughly translated to 'zhang' How can I hook such programs (I believe one is called 'mspy.exe', from Microsoft, which I'm lead to believe comes with Microsoft versions of XP) into a WPF text box? Right now, the user can enter text either by using their keyboard or by using an on-screen keyboard, so I will probably need to capture the event of a keypress from either source and feed it to some OS event or to MSPY.exe or some similar program. Or is there some other way to enter pinyin and have it converted to Mandarin? Is there a program other than MSPY I should look at? EDIT: For those of you who think that this should 'just work', it does not. Chinese character entry will work just fine if entering text into notepad or the start-run menu or whatever, but it will not work in WPF. That's the key to this question: how do I enable WPF entry? There's the Google Pinyin and Sogou pinyin, but the websites are in Mandarin or Chinese or something similar and I don't read the language.

  • Good mobile oriented GWT widget library alternatives

    - by Michael Donohue
    I've been developing a travel planning site - tripgrep.com - which is built on appengine, GWT and smartgwt, among other technologies. It is still early days, and the site is now working well on my development environment, which is either a windows or mac computer. However, I am frequently talking up the website to my friends when we are at a bar or other venue, so I am standing there while they try to access the site via an iPhone, Android or Blackberry - I've witnessed all three. It has been painfully obvious that the browser based frontend takes a long time to download on a mobile device. I am pretty sure this is because of the javascript download for SmartGWT. So, I would like to look at alternatives to SmartGWT. What I like about SmartGWT is that it has a reasonable look and feel out of the box - I don't need to learn any design or css and it has an office application look. This is considerably better than the GWT built-in widgets, which just get a blue border. The better look-and-feel is why I went with SmartGWT early on. However, the slow load times are killing me on these mobile demos. So now I want a fast loading widget alternative that has good look-and-feel out of the box. The features I care about are: tabs, good form layout, Google maps API integration, grid data viewing. If those are all available in a library that loads quickly on a mobile device, then that's the library I want.

  • Java - How to detect that the internet connection has got disconnected through a java desktop applic

    - by Yatendra Goel
    I am developing a Java Desktop Application that access internet. It is a multi-threaded application, each thread do the same work (means each thread is an instance of same Thread class). Now, as all the threads need internet connection to be active, there should be some mechanism that detects whether an internet connection is active or not. Q1. How to detect whether the internet connection is active or not? Q2. Where to implement this internet-status-check-mechanism code? Should I start a separate thread for checking internet status regularly and notifies all the threads when the status changes from one state to another? Or should I let each thread check for the internet-status itself? Q3. This issue should be a very common issue as every application accessing an internet should deal with this problem. So how other developers usually deal with this problem? Q4. If you could give me a reference to a good demo application that addresses this issue then it would greatly help me.

  • About AMR audio file playing issue on different devices

    - by user352537
    I have got a quite strange problem here. I am developing an IM software and need to play audio files recorded by another client on Android. The same audio file I've got can be played with AVAudioPlayer on 3GS(IOS 4.2.1) device and simulator 4.2. But when I tried by play it on iPhone4(iOS 4.3.3), the function "play" always return NO. I also tried with two iPhone devices, the audio files recorded by iPhone client can be played on both 3GS and iPhone4. So I asked the Android developers about the record parameters they've used. They said that the "AudioEncoder" used by them was "DEFAULT". There are also some other parameters as following: **private AudioEncoder() {} public static final int DEFAULT = 0; /** AMR (Narrowband) audio codec */ public static final int AMR_NB = 1; /** @hide AMR (Wideband) audio codec */ public static final int AMR_WB = 2; /** @hide AAC audio codec */ public static final int AAC = 3; /** @hide enhanced AAC audio codec */ public static final int AAC_PLUS = 4; /** @hide enhanced AAC plus audio codec */ public static final int EAAC_PLUS = 5;** Does anybody know what's the matter?

  • How to TDD Asynchronous Events?

    - by Padu Merloti
    The fundamental question is how do I create a unit test that needs to call a method, wait for an event to happen on the tested class and then call another method (the one that we actually want to test)? Here's the scenario if you have time to read further: I'm developing an application that has to control a piece of hardware. In order to avoid dependency from hardware availability, when I create my object I specify that we are running in test mode. When that happens, the class that is being tested creates the appropriate driver hierarchy (in this case a thin mock layer of hardware drivers). Imagine that the class in question is an Elevator and I want to test the method that gives me the floor number that the elevator is. Here is how my fictitious test looks like right now: [TestMethod] public void TestGetCurrentFloor() { var elevator = new Elevator(Elevator.Environment.Offline); elevator.ElevatorArrivedOnFloor += TestElevatorArrived; elevator.GoToFloor(5); //Here's where I'm getting lost... I could block //until TestElevatorArrived gives me a signal, but //I'm not sure it's the best way int floor = elevator.GetCurrentFloor(); Assert.AreEqual(floor, 5); } Edit: Thanks for all the answers. This is how I ended up implementing it: [TestMethod] public void TestGetCurrentFloor() { var elevator = new Elevator(Elevator.Environment.Offline); elevator.ElevatorArrivedOnFloor += (s, e) => { Monitor.Pulse(this); }; lock (this) { elevator.GoToFloor(5); if (!Monitor.Wait(this, Timeout)) Assert.Fail("Elevator did not reach destination in time"); int floor = elevator.GetCurrentFloor(); Assert.AreEqual(floor, 5); } }

  • Follow the links of the tab in jquery ui tab

    - by Aakash Chakravarthy
    Hello, I have jquery tabs like <ul id="tabsList"> <li><a href="#tab-1">Name 1</a></li> <li><a href="#tab-2">Name 2</a></li> <li><a href="http://www.google.com/">Name 3</a></li> </ul> <div id="tab-1">content 1</div> <div id="tab-2">content 2</div> the first two tabs load the respective divs. But the third one should go to google.com, instead it does nothing. It just adds http://example.com/index.html#ui-tabs-[object Object] to the url. I am developing a wordpress plugin and the admin page needs a tab interface. I tested this in a local server and not working update: i don't want to load google.com inside the page. It should open the webpage in new tab/window like ordinary links do.

  • Development/runtime Licensing mechanism for a C# class library?

    - by Darryl
    I'm developing a .Net class library (a data provider) and I'm starting to think about how I would handle licensing the library to prospective purchasers. By licensing, I mean the mechanics of trying to prevent my library from being used by those who haven't purchased it, not the software license (i.e., Apache, Gnu, etc). I've never dealt with licensing, and in the past, I've always developed apps, not libraries. I don't want to make things difficult for my customers; know it is not possible to make it ironclad. Just some mechanism that gives me decent protection without making the customer jump through hoops or gnash their teeth. I think the mechanism would check for a valid license when the class is being used in development mode, and not in runtime mode (when the customer's software is released to their customers). I think libraries are typically sold per developer, but I'm not sure how that could be accomplished without making the mechanism odious for my customers; maybe that gets left to the honor system. I Googled this and found many approaches. Ideally, I'd like to do something that is generally accepted and common, the "right" way class libraries are licensed, if that exists, rather than making my customers deal with yet another license mechanism. A firm push in the right direction will be greatly appreciated!

  • Rails 1.0 - Using composed_of gives me a wrong number of arguments (1 for 5) error

    - by Tristan Havelick
    I am developing a Rails 1.0 application (I can't upgrade, it's a strange situation) for which I am trying to use the :composed_of functionality.

  • Does Apple's Reachability work with 3G connectivity?

    - by rickharrison
    I am developing an iPad application, and I am trying to figure out the best way to decide if a user can connect to the Internet. If the user has no connectivity, I will load cached data, otherwise I will load new data. I am trying to use Apple's reachability class for this, and I wanted to see if I am doing this correctly. In applicationDidFinishLaunchingWithOptions, I am doing this: [[NSNotificationCenter defaultCenter] addObserver: self selector: @selector(reachabilityChanged:) name: kReachabilityChangedNotification object: nil]; Reachability hostReach = [[Reachability reachabilityWithHostName: @"www.apple.com"] retain]; [hostReach startNotifer]; Then my reachabilityChanged: looks like this: - (void)reachabilityChanged:(NSNotification* )note { Reachability *curReach = [note object]; self.internetConnectionStatus = [curReach currentReachabilityStatus]; if (internetConnectionStatus == NotReachable) { [viewController getDataOffline]; } else { if (![[NSUserDefaults standardUserDefaults] objectForKey:kFIRST_LAUNCH]) [viewController getCurrentLocation]; else [viewController getData]; } } Right now, this is working perfectly for WiFi iPads. I just want to make sure that this will work for 3G iPads. Could you please let me know if I am doing this correctly or not?

  • Grails UrlMappings with .html

    - by Glennn
    I'm developing a Grails web application (mainly as a learning exercise). I have previously written some standard Grails apps, but in this case I wanted to try creating a controller that would intercept all requests (including static html) of the form: <a href="/testApp/testJsp.jsp">test 1</a> <a href="/testApp/testGsp.gsp">test 2</a> <a href="/testApp/testHtm.htm">test 3</a> <a href="/testApp/testHtml.html">test 4</a> The intent is to do some simple business logic (auditing) each time a user clicks a link. I know I could do this using a Filter (or a range of other methods), however I thought this should work too and wanted to do this using a Grails framework. I set up the Grail UrlMappings.groovy file to map all URLs of that form (/$myPathParam?) to a single controller: class UrlMappings { static mappings = { "/$controller/$action?/$id?"{ constraints { } } "/$path?" (controller: 'auditRecord', action: 'showPage') "500"(view:'/error') } } In that controller (in the appropriate "showPage" action) I've been printing out the path information, for example: def showPage = { println "params.path = " + params.path ... render(view: resultingView) } The results of the println in the showPage action for each of my four links are testJsp.jsp testGsp.gsp testHtm.htm testHtml Why is the last one "testHtml", not "testHtml.html"? In a previous (Stack Overflow query) Olexandr encountered this issue and was advised to simply concatenate the value of request.format - which, indeed, does return "html". However request.format also returns "html" for all four links. I'm interested in gaining an understanding of what Grails is doing and why. Is there some way to configure Grails so the params.path variable in the controller shows "testHtml.html" rather than stripping off the "html" extension? It doesn't seem to remove the extension for any other file type (including .htm). Is there a good reason it's doing this? I know that it is a bit unusual to use a controller for static html, but still would like to understand what's going on.

  • How to create refresh statements for TableAdapter objects in Visual Studio?

    - by Mark Wilkins
    I am working on developing an ADO.NET data provider and an associated DDEX provider. I am unable to convince the Visual Studio TableAdapater Configuration Wizard to generate SQL statements to refresh the data table after inserts and updates. It generates the insert and delete statements but will not produce the select statements to do the refresh. The functionality referred to can be accessed by dropping a table from the Server Explorer (inside Visual Studio) onto a DataSet (e.g., DataSet1.xsd). It creates a TableAdapter object and configures SELECT, UPDATE, DELETE, and INSERT statements. If you right click on the TableAdapter object, the context menu has a “Configure” option that starts the “TableAdapter Configuration Wizard”. The first dialog of that wizard has an Advanced Options button, which leads to an option titled “Refresh the data table”. When used with SQL Server tables, that option causes a statement of the form “select field1, field2, …” to be added on to the end of the commands for the TableAdapter’s InsertCommand and UpdateCommand. Do you have any idea what type property or interface might need to be exposed from the DDEX provider (or maybe the ADO.NET data provider) in order to make Visual Studio add those refresh statements to the update/insert commands? The MSDN documentation for the Advanced SQL Generation Options Dialog Box has a note stating, “Refreshing the data table is only supported on databases that support batching of SQL statements.” This seems to imply that a .NET data provider might need to expose some property indicating such behavior is supported. But I cannot find it. Any ideas?

  • C# override WndProc in Control level to detect

    - by Nullstr1ng
    I have overridden WndProc in UserControl level to detect MouseDown, MouseUp, and MouseMove to any Control added in that UserControl. protected override void WndProc(ref Message m) { Point mouseLoc = new Point(); switch (m.Msg) { case WM_LBUTTONDOWN: System.Diagnostics.Debug.WriteLine("mouse down"); //this.OnMouseDown(new MouseEventArgs(MouseButtons.Left, 1, mouseLoc.X, mouseLoc.Y, 0)); break; case WM_LBUTTONUP: System.Diagnostics.Debug.WriteLine("mouse up"); //this.OnMouseDown(new MouseEventArgs(MouseButtons.Left, 1, mouseLoc.X,mouseLoc.Y, 0)); break; case WM_MOUSEMOVE: int lParam = m.LParam.ToInt32(); //mouseLoc.X = lParam & 0xFFFF; //mouseLoc.Y = (int)(lParam & 0xFFFF0000 >> 16); mouseLoc.X = (Int16)m.LParam; mouseLoc.Y = (Int16)((int)m.LParam >> 16); System.Diagnostics.Debug.WriteLine("mouse move: " + mouseLoc.X + ", " + mouseLoc.Y); //this.OnMouseDown(new MouseEventArgs(MouseButtons.Left, 1, mouseLoc.X,mouseLoc.Y, 0)); break; } base.WndProc(ref m); } MouseMove, Down, and Up are working when the mouse pointer is in UserControl but when the mouse pointer is on other control (inside my UserControl) it doesn't work. Am I doing something wrong? Currently developing a flick and scroll control.

  • JBoss: What does the warning EJBTHREE-1246 from the InterceptorRegistry mean?

    - by Simon Lehmann
    I am currently developing an EJB 3.0 based application on the JBoss AS 5.0.0.GA and just recently the following warning showed up in the server log: 09:50:19,735 WARN [InterceptorsFactory] EJBTHREE-1246: Do not use InterceptorsFactory with a ManagedObjectAdvisor, InterceptorRegistry should be used via the bean container 09:50:19,735 WARN [InterceptorsFactory] EJBTHREE-1246: Do not use InterceptorsFactory with a ManagedObjectAdvisor, InterceptorRegistry should be used via the bean container 09:50:19,735 WARN [InterceptorRegistry] applicable interceptors is non-existent for ... ... The warnings are generated as soon as an EJB (a stateless session bean) is injected into a backing bean of my JSF web-application. The beans do work without problems though, but I still would like to know where that warning comes from and what I can do to avoid it. I have already searched a bit around, but haven't found a good answer (some say, bean developers do not have to worry, but its a warning, so I'd like to have a better solution): http://www.jboss.com/index.html?module=bb&op=viewtopic&t=147292 http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4180366 http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4140136 JBoss JIRA Issue about the warning (Not that helpful in my opinion) So has anyone an explanation what causes the warning (in terms of a bean developer, not application server developer) and what to do to avoid it? Update: I've just upgraded JBoss to 5.0.1.GA (Download, Release-Notes) but unfortunatly the warning still appears.

  • Java: Initializing a public static field in superclass that needs a different value in every subclas

    - by BinaryMuse
    Good evening, I am developing a set of Java classes so that a container class Box contains a List of a contained class Widget. A Widget needs to be able to specify relationships with other Widgets. I figured a good way to do this would be to do something like this: public abstract class Widget { public static class WidgetID { // implementation stolen from Google's GWT private static int nextHashCode; private final int index; public WidgetID() { index = ++nextHashCode; } public final int hashCode() { return index; } } public abstract WidgetID getWidgetID(); } so sublcasses of Widget could: public class BlueWidget extends Widget { public static final WidgetID WIDGETID = new WidgetID(); @Override public WidgetID getWidgetID() { return WIDGETID; } } Now, BlueWidget can do getBox().addWidgetRelationship(RelationshipTypes.SomeType, RedWidget.WIDGETID, and Box can iterate through it's list comparing the second parameter to iter.next().getWidgetID(). Now, all this works great so far. What I'm trying to do is keep from having to declare the public static final WidgetID WIDGETID in all the subclasses and implement it instead in the parent Widget class. The problem is, if I move that line of code into Widget, then every instance of a subclass of Widget appears to get the same static final WidgetID for their Subclassname.WIDGETID. However, making it non-static means I can no longer even call Subclassname.WIDGETID. So: how do I create a static WidgetID in the parent Widget class while ensuring it is different for every instance of Widget and subclasses of Widget? Or am I using the wrong tool for the job here? Thanks!

  • Java - encrypt / decrypt user name and password from a configuration file

    - by nzpcmad
    We are busy developing a Java web service for a client. There are two possible choices: Store the encrypted user name / password on the web service client. Read from a config. file on the client side, decrypt and send. Store the encrypted user name / password on the web server. Read from a config. file on the web server, decrypt and use in the web service. The user name / password is used by the web service to access a third-party application. The client already has classes that provide this functionality but this approach involves sending the user name / password in the clear (albeit within the intranet). They would prefer storing the info. within the web service but don't really want to pay for something they already have. (Security is not a big consideration because it's only within their intranet). So we need something quick and easy in Java. Any recommendations? The server is Tomkat 5.5. The web service is Axis2. What encrypt / decrypt package should we use? What about a key store? What configuration mechanism should we use? Will this be easy to deploy?

  • Error returning Ajax in IE7

    Hi everybody! It's my first question here. First of all, sorry for my 'not perfect' english... I'm developing an ASP.NET MVC application with AJAX. I have the following code in the View: <% using(Html.BeginForm(null, "Home", FormMethod.Post, new{id="formcpf"})){ %> <p> <input name="tipo" type="radio" value="GeraCPF" /> CPF <input type="radio" name="tipo" value="GeraCNPJ" /> CNPJ </p> <p> <input type="submit" id="sbmt" value="Gerar" /> <br /><br /> <span id="lblCPF" class="respostaBG"></span> </p> <%} % and the following Javascript to call an Ajax request: $(document).ready(function() { $("form#formcpf").submit(function(event) { $(this).attr("action", $("input[@name='tipo']:checked").val()); event.preventDefault(); hijack(this, update_sessions, "html"); }); }); function hijack(form, callback, format) { $.ajax({ url: form.action, type: form.method, dataType: format, data: $(form).serialize(), success: callback }); } function update_sessions(result) { $("#lblCPF").html(result); } in Firefox and Chrome works fine, but in IE7 sometimes returns the value into the label, sometimes not. I have to keep submiting to get the return. Anyone could help?

  • Efficient method to calculate the rank vector of a list in Python

    - by Tamás
    I'm looking for an efficient way to calculate the rank vector of a list in Python, similar to R's rank function. In a simple list with no ties between the elements, element i of the rank vector of a list l should be x if and only if l[i] is the x-th element in the sorted list. This is simple so far, the following code snippet does the trick: def rank_simple(vector): return [rank for rank in sorted(range(n), key=vector.__getitem__)] Things get complicated, however, if the original list has ties (i.e. multiple elements with the same value). In that case, all the elements having the same value should have the same rank, which is the average of their ranks obtained using the naive method above. So, for instance, if I have [1, 2, 3, 3, 3, 4, 5], the naive ranking gives me [0, 1, 2, 3, 4, 5, 6], but what I would like to have is [0, 1, 3, 3, 3, 5, 6]. Which one would be the most efficient way to do this in Python? Footnote: I don't know if NumPy already has a method to achieve this or not; if it does, please let me know, but I would be interested in a pure Python solution anyway as I'm developing a tool which should work without NumPy as well.

  • How to develop JSP/Servlets Web App using MVC pattern?

    - by A.S al-shammari
    I'm developing a JSP/Servlets web app (no frameworks). I want to use MVC pattern. I designed my project like this : Controller :a servlet that reads a request, extracts the values,communicates with model objects and gives information to a JSP page. View : JSP Pages. Model : Java Classes / Java Beans .. etc . The problem : Index.jsp is the starting point (default page) in my web site. So, the Index.jsp becomes the controller to parse the request! .For example , the following request : index.jsp?section=article&id=10 parsed in index.jsp as following : <div class="midcol"> <!-- Which section? --> <%String fileName = request.getParameter("section"); if (fileName == null) { fileName = "WEB-INF/jspf/frontpage.jsp"; } else { fileName = "WEB-INF/jspf/" + fileName + ".jsp"; } %> <jsp:include page='<%= fileName%>' /> </div> Here, I can't force the servlet to be a controller .. because the index.jsp is the controller here since it's the starting point! Is there any solution to forward the request from index.jsp to the servlet and then go back to index.jsp ? Or any solution that achieves the MVC goal - the servlet should be the controller - ? I'm thinking of making a FrontPageController servlet as default page instead of index.jsp ! but I don't know if it's a perfect idea ?!

  • Rails - handling global site settings

    - by egarcia
    I'm developing a new rails application which is supposed to be installed several times in order to implement several sites. There are some things, like the "Site Title" or the "Default Number of Items per Page" that clearly belong to a "global settings" table / config file. I've made a list of the things I think I'll need: ActiveRecord model that is capable of: Storing different kinds of data. I suppose this would be accomplished encoding the values on a string on the db, probably with a "type" field. Indexing settings by name Validations based on a "type" attribute (i.e. don't accept invalid dates on "date" settings) Validations based on a allows_nil property. A controller that allows me to change settings via views. I'm pretty sure I could implement this myself, but I'm not willing to reinvent the wheel. I've done some searching, but I could only find rails-settings, which doesn't really serve me: I need a proper model & controller so I can use declarative-authorization, and it does not provide any controller or view facilities. Is there a gem or plugin out there that implements what I want, or any library I should look at? Thanks a lot.

  • Porting WebGL game to iPhone's native OpenGL?

    - by ArtPulse
    We are developing a web game that uses WebGL for the two biggest parts of it. Working with HTML / CSS was too slow and too limited, so it's off the table. Thing is, iOS does not support WebGL publicly just yet, only on iAd. It is my guess Apple will eventually support it once the security issues they and Microsoft claim it has are fixed, and looks stable enough. Problem is, if Apple does not do this by the release of the next mayor iOS version, then we will have in our hands a mobile WebGL game that does not run. 6 months of development and testing to waste. So, questions: If that was the case, how viable (regarding amount of time) is it porting the WebGL part of the game to native iPhone OpenGL? I'm afraid that porting will take longer than the development of the game itself. I saw posts on Stack Overflow (like this) that suggested, on Android, adding the OpenGL interface manually to a WebKit element. It'd be slower than native. But either way... Is this something that could be accepted in the AppStore? Apple is very restrictive with these kind of stuff... Thank you all for your time!

  • dialing on iphone/ipod touch not working with documented procedures

    - by dave
    I'm trying to set up an iphone app to the phone number of a various sports store using the tel:// url passing method- I am developing on an ipod touch- usually on the touch you see the error message "Unsupported URL - This URL wasn't loaded tel://99887766" when you try and dial a number. I cant get this message to appear on the simulator or the ipod touch. do I need to do some sort of fancy signing before the app will dial properly? I am using this code: [[UIApplication sharedApplication] openURL:[NSURL URLWithString:[NSString stringWithFormat:@"tel:%@", [selectedBar phoneNumber]]]]; and I've tried adding the slashes: [[UIApplication sharedApplication] openURL:[NSURL URLWithString:[NSString stringWithFormat:@"tel://%@", [selectedBar phoneNumber]]]]; but neither work. I have also tried this way: [[UIApplication application] openURL:[NSURL URLWithString:@"tel://99887766"]]; and this way: NSMutableString *phone = [[@"+ 12 34 567 89 01" mutableCopy] autorelease]; [phone replaceOccurrencesOfString:@" " withString:@"" options:NSLiteralSearch range:NSMakeRange(0, [phone length])]; [phone replaceOccurrencesOfString:@"(" withString:@"" options:NSLiteralSearch range:NSMakeRange(0, [phone length])]; [phone replaceOccurrencesOfString:@")" withString:@"" options:NSLiteralSearch range:NSMakeRange(0, [phone length])]; NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"tel:%@", phone]]; [[UIApplication sharedApplication] openURL:url]; No matter what i do i can't get any response from the simulator / ipod touch that it is dealing with a phone number- When I press the button associated with this code, it doesnt crash, it's like its processed it and decided not to do anything. i even put an NSLog(@"button called"); in just before the code to confirm the button was working, which it is.

  • GUI toolkit for Unicode text app?

    - by wrp
    In developing a tool for processing text in exotic scripts, I'm having trouble choosing a GUI toolkit. The main part of the interface is to be a text editor, not much more elaborate than Notepad, but with its own input method editor. It is to be extensible in a scripting language so that non-programmers can develop their own input methods and display routines. It will be assumed that all files are UTF-8. More elaborate support like regexes is not needed. The main sticking points are: characters beyond the Basic Multilingual Plane right-to-left and bi-directional text extension in a scripting language cross-platform Linux/Windows/OS X My first choice was Tcl/Tk, but it lacks bidi and going beyond the BMP seems dodgy. At the other extreme, I've considered Qt with embedded ECMAScript, but that might be heavier and less malleable than I would like. I'm even thinking about making it browser based, but I'm concerned that the IM for large scripts would be too heavy for client-side processing. I've also looked at a few similar projects in Java, but the quality of the font rendering in SWING has been unacceptable. What are your experiences in handling Unicode with various toolkits? Are there other serious issues I haven't considered? What would you recommend for doing this in the lightest way?

  • Bizarre Javascript JSON undefined error

    - by Nate C-K
    I'm experiencing an error that I haven't been able to find any mention of anywhere. I'm developing an AJAX-enabled WCF web service with ASP.NET. In my ASP.NET master page's , I included the json.js file, copied fresh from json.org. When I run the page, it fails (VS 2008 catches a Javascript exception) on the first line of code in json.js (following lots of comments), which is: JSON = JSON || {}; The error says that JSON is undefined: Microsoft JScript runtime error: 'JSON' is undefined Well, duh! That's why the line is testing if it's defined and if so setting it to an empty object! It is supposed to be undefined, right? Last I heard it was not an error in Javascript to perform such an operation on an undefined variable. Can anyone give me a clue as to what's going on here? I suspect it's something gone wrong elsewhere that's somehow causing this problem. I don't have deep experience with either Javascript or ASP.NET so it might be that I'm missing some common gotcha in the setup.
