  • Error // Usage: rails new APP_PATH [options] // when running 'rails server'

    - by madphill
    Background info: I'm using GIT to get a repository of a project with Ruby files in it. The project lives in my SITES folder under home directory on my Mac. I have Ruby: 1.8.7 I have just upgraded Rails to: 3.0.3 All I am trying to accomplish is to be able to render localhost.com:3000 in my browser of the GIT project i've already downloaded so I can work on it locally. I ran the command 'rails server' and was returned the message below:: Usage: rails new APP_PATH [options] Options: [--skip-gemfile] # Don't create a Gemfile -m, [--template=TEMPLATE] # Path to an application template (can be a filesystem path or URL) -d, [--database=DATABASE] # Preconfigure for selected database (options: mysql/oracle/postgresql/sqlite3/frontbase/ibm_db) # Default: sqlite3 -O, [--skip-active-record] # Skip Active Record files -J, [--skip-prototype] # Skip Prototype files -T, [--skip-test-unit] # Skip Test::Unit files [--dev] # Setup the application with Gemfile pointing to your Rails checkout -r, [--ruby=PATH] # Path to the Ruby binary of your choice # Default: /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby -G, [--skip-git] # Skip Git ignores and keeps -b, [--builder=BUILDER] # Path to an application builder (can be a filesystem path or URL) [--edge] # Setup the application with Gemfile pointing to Rails repository Runtime options: -f, [--force] # Overwrite files that already exist -s, [--skip] # Skip files that already exist -p, [--pretend] # Run but do not make any changes -q, [--quiet] # Supress status output Rails options: -h, [--help] # Show this help message and quit -v, [--version] # Show Rails version number and quit Description: The 'rails new' command creates a new Rails application with a default directory structure and configuration at the path you specify. Example: rails new ~/Code/Ruby/weblog This generates a skeletal Rails installation in ~/Code/Ruby/weblog. See the README in the newly created application to get going.

  • Java: attributes order in .jsp getting inversed

    - by NoozNooz42
    Every single time I've read about the meta tags, the attribute where in this order for the description: <meta name="description" content="..." /> First name, then content. It's also like that in the Google Webmaster documentation. Basically, it's like that everywhere. Now in a .jsp (in XML notation) I've got the following: <meta name="description" content="${metadesc}"/> So it's name first, then content. Yet on the generated webpage, I get this: <meta content="...(200 chars or so here making it a very long line)..." name="description"/> Somehow the attributes have been inversed. Because the content follows the official W3C and Google recommendations, the content is a bit less than 200 characters long, which makes it a major pain to "visually verify" that the name attribute is correctly there (I've got to scroll). Anyway... Why are these attribute not appearing in the order defined in the .jsp? Can I force them to appear in the same order as I wrote them in my .jsp? I realize the resulting tag may be valid... But I can also imagine a lot of very creative ways to have valid tags which users would be very upset about. Does this make any sense to inverse these attributes? EDIT wow, just wow... If I invert the attributes in my .jsp (that is, writing them in the "wrong" order), then they appear as I want them to appear in the generated web page. (Tomcat 6.0.26 btw)

  • Why is a CoreData forceFetch required after a delete on the iPad but not the iPhone?

    - by alyoshak
    When the following code is run on the iPhone the count of fetched objects after the delete is one less than before the delete. But on the iPad the count remains the same. This inconsistency was causing a crash on the iPad because elsewhere in the code, soon after the delete, fetchedObjects is called and the calling code, trusting the count, attempts access to the just-deleted object's properties, resulting in a NSObjectInaccessibleException error (see below). A fix has been to use that commented-out call to performFetch, which when executed makes the second call to fetchObjects yield the same result as on the iPhone without it. My question is: Why is the iPad producing different results than the iPhone? This is the second of these differences that I've discovered and posted recently. -(NSError*)deleteObject:(NSManagedObject*)mo; { NSLog(@"\n\nNum objects in store before delete: %i\n\n", [[self.fetchedResultsController fetchedObjects] count]); [self.managedObjectContext deleteObject:mo]; // Save the context. NSError *error = nil; if (![self.managedObjectContext save:&error]) { } // [self.fetchedResultsController performFetch:&error]; // force a fetch NSLog(@"\n\nNum objects in store after delete (and save): %i\n\n", [[self.fetchedResultsController fetchedObjects] count]); return error; } (The full NSObjectInaccessibleException is: "Terminating app due to uncaught exception 'NSObjectInaccessibleException', reason: 'CoreData could not fulfill a fault for '0x1dcf90 <x-coredata://DC02B10D-555A-4AB8-8BC4-F419C4982794/Blueprint/p"

  • Android ScrollView jumps around when resized

    - by Mike
    I have a ScrollView that contains an number of other views (TextViews, ImageViews, etc.). The ScrollView is taller than the screen. I have an AsyncTask that updates the children of the ScrollView based on an http response. I've discovered an interesting behavior that I can't figure out how to work around. If I set any of the children's visibilities to View.INVISIBLE as part of the AsyncTask.onPostExecute(), everything works fine. However, if I set any of the children's visibilities to View.GONE, the ScrollView jumps down from the top when onPostExecute() is called. Exactly how far seems to vary. I'm guessing that re-laying out the ScrollView is causing it to scroll away from the top for some reason. So the question is: is there a way to either prevent or work around this behavior? PS. Using ScrollView.jump(FOCUS_UP) as a workaround isn't ideal since that'll force the user to the top even if they had intended to scroll down. EDIT: Actually, I was wrong. The problem wasn't with a child view being marked gone, the problem was with a sibling view being marked gone and the ScrollView getting resized. My ScrollView is inside a LinearLayout that also contains a Button. When the button is set to GONE, the ScrollView gets resized to take up the available space, causing it to scroll away from the top. Different cause, still looking for a workaround though if possible.

  • Embedding/deploying custom font in .NET app

    - by Swingline Rage
    Is there an official way to distribute (deploy) a specific font with a .NET application? We have a (public domain) "LED font" that prints numbers with the retro LED instrumentface look. This is a standard True Type or Open Type font like any other except it looks funky. Obviously for that to work, this font needs to be on the user's machine. But we'd prefer to not force the user to "install our special font into your font folder". We'd prefer to either load a Font object directly from the TTF, or programatically install the font so it's available. How do applications handle this sort of things? Eg, I notice Adobe XYZ installs various fonts on the system without user intervention. That's what we'd like to do. EDIT: okay, ideally, we'd prefer not to install the font directly. We don't want our nifty themed LED font showing up in the user's font dropdown in MS Word. We'd prefer to use this font, but restrict its use or appearance to our app. Any way to do this? Thanks!

  • C# string.Split() Matching Both Slashes?

    - by Sheep Slapper
    I've got a .NET 3.5 web application written in C# doing some URL rewriting that includes a file path, and I'm running into a problem. When I call string.Split('/') it matches both '/' and '\' characters. Is that... supposed to happen? I assumed that it would notice that the ASCII values were different and skip it, but it appears that I'm wrong. // url = 'someserver.com/user/token/files\subdir\file.jpg string[] buffer = url.Split('/'); The above code gives a string[] with 6 elements in it... which seems counter intuitive. Is there a way to force Split() to match ONLY the forward slash? Right now I'm lucky, since the offending slashes are at the end of the URL, I can just concatenate the rest of the elements in the string[], but it's a lot of work for what we're doing, and not a great solution to the underlying problem. Anyone run into this before? Have a simple answer? I appreciate it!

  • Can I ignore a SIGFPE resulting from division by zero?

    - by Mikeage
    I have a program which deliberately performs a divide by zero (and stores the result in a volatile variable) in order to halt in certain circumstances. However, I'd like to be able to disable this halting, without changing the macro that performs the division by zero. Is there any way to ignore it? I've tried using #include <signal.h> ... int main(void) { signal(SIGFPE, SIG_IGN); ... } but it still dies with the message "Floating point exception (core dumped)". I don't actually use the value, so I don't really care what's assigned to the variable; 0, random, undefined... EDIT: I know this is not the most portable, but it's intended for an embedded device which runs on many different OSes. The default halt action is to divide by zero; other platforms require different tricks to force a watchdog induced reboot (such as an infinite loop with interrupts disabled). For a PC (linux) test environment, I wanted to disable the halt on division by zero without relying on things like assert.

  • Prototype VS jQuery

    - by aSeptik
    Hi All guys! First of, thank's for your time; then i want go directly to the point by saying that, i don't want to open another "Yet Another Js VS Js" 3d , the web is almost busy of this! I want also make a premise, i have used both theese js frameworks and i love it and i know, that there are a lot of good js frameworks around, maybe better then this two; but, as you know we need to be perfomant and quickly by doing our works, so i want keep this two, that are the most famous and therefore have a great community support! now, if you are going to say me, that the choise depends on what i'm going to do!? then i can think, hey, in the end they are both javascript and they have almost the same methods and functions and for achieve a task they needs almost the same lines of code! So i want hear from you guys, from you that have really used one of theese, for a real Rich Internet Application what are the real points of force and what the weaknesses you find!? Regards.

  • alternative to JQuery form.submit() to do ajax post

    - by BluntTool
    Hello, I have a mvc2 application with a view like this <% using (Ajax.BeginForm("UserApprove", new { id = Model.id }, new AjaxOptions() { UpdateTargetId = "statusLights", OnSuccess = "HideButtons" }, new { id = "UserApprove" })) {%> <input type="button" value="Approve" onclick="$('#dialogApprove').dialog('open')" /> <div id="dialogApprove" title="Confirm"> <p> Are you sure you want to approve this request? </p> </div> <% } %> FYI, the controller returns a partial view back. I used to not have the jquery dialog and just simple a <input type="Submit" value="Approve" /> that used to work fine I added the jquery dialog and I have something like this to initialize the dialog. $("#dialogApprove").dialog({ autoOpen: false, draggable: true, resizable: false, buttons: { "Cancel": function() { $(this).dialog("close") }, "Approve": function() { $("#UserApprove").submit(); $(this).dialog("close"); } } }); The $("#UserApprove").submit(); does not seem to be doing an ajax post. It comes back with just the text from the partial view returned in a new page. I dont want to use the jquery form plugin which has .ajaxSubmit(). Is there any other way to force an ajax post from the jquery dialog "approve" button?

  • Scheduling of tasks to a single resource using Prolog

    - by Reed Debaets
    I searched through here as best I could and though I found some relevant questions, I don't think they covered the question at hand: Assume a single resource and a known list of requests to schedule a task. Each request includes a start_after, start_by, expected_duration, and action. The goal is to schedule the tasks for execution as soon as possible while keeping each task scheduled between start_after and start_by. I coded up a simple prolog example that I "thought" should work but I've been unfortunately getting errors during run time: "=/2: Arguments are not sufficiently instantiated". Any help or advice would be greatly appreciated startAfter(1,0). startAfter(2,0). startAfter(3,0). startBy(1,100). startBy(2,500). startBy(3,300). duration(1,199). duration(2,199). duration(3,199). action(1,'noop1'). action(2,'noop2'). action(3,'noop3'). can_run(R,T) :- startAfter(R,TA),startBy(R,TB),T>=TA,T=<TB. conflicts(T,R1,T1) :- duration(R1,D1),T=<D1+T1,T>T1. schedule(R1,T1,R2,T2,R3,T3) :- can_run(R1,T1),\+conflicts(T1,R2,T2),\+conflicts(T1,R3,T3), can_run(R2,T2),\+conflicts(T2,R1,T1),\+conflicts(T2,R3,T3), can_run(R3,T3),\+conflicts(T3,R1,T1),\+conflicts(T3,R2,T2). % when traced I *should* see T1=0, T2=400, T3=200 Edit: conflicts goal wasn't quite right: needed extra TT1 clause. Edit: Apparently my schedule goal works if I supply valid Request,Time pairs ... but I'm stucking trying to force prolog to find valid values for T1..3 when given R1..3?

  • Deployment Setup (.Net) - Search target machine -> Registry search (64 bit)

    - by Joonas Kirsebom
    I have a windows installer project which installs some software (winform, service, mce addin). During the installation I need to search the machine for a registry key. This is done with with the "Launch Condition" - "Add Registry Search" (Deployment Project). I have filled out all the properties right, and checked against the regestry that the value actually can be found. The problem is that the "Registry Search" searches in the x86 part of the registry (HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\...) although my system is a x64 and the deployment setup is also set to x64. Does anyone know how to force the "Registry Search" to search the x64 registry? Or know about a workaround? The weird thing about this, is that Registry setting in the deployment setup is writing to the right registry (x64). My idea is that the "Registry Search" program is only developed to the x86 architecture, and therefore can't read the right registry. I found this article from microsoft, so it seams that they know about this problem. https://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?FeedbackID=110105&wa=wsignin1.0#details My system is: Windows 7 64bit Visual Studio 2008

  • Multiple, Simultaneous Factories and Protocols in Twisted: Same Service, Different Ports

    - by RichardCroasher
    Greetings, Forum. I'm working on a program in Python that uses Twisted to manage networking. The basis of this program is a TCP service that is to listen for connections on multiple ports. However, instead of using one Twisted factory to handle a protocol object for each port, I am trying to use a separate factory for each port. The reason for this is to force a separation among the groups of clients connecting to the different ports. Unfortunately, it appears that this architecture isn't quite working: clients that connect to one port appear to be available among all the factories (e.g., the protocol class used by each factory includes a 'self.factory.clients.append (self)' statement...instead of adding a given client to just the factory for a particular port, the client is added to all factories), and whenever I shutdown service on one port the listeners on all ports also stop. I've been working with Twisted for a short while, and fear I simply don't fully understand how its factory classes are managed. My question is: is it simply not possible to have multiple, simultaneous instances of the same factory and same protocol in use across different ports (without these instances stepping on each other's toes)?

  • Div click and AUTOCOMPLETE password dialog problem

    - by ticky
    And what if you want to autocomplete passwords? I am using similar thing here... I am using Div (id=loginButton) and it has some image - I don't want button control in MVC application (), neither image button. I have hidden input control which is hidden button actually (id=submit_btn). So, on div's (id=loginButton) click, I want to call hidden input control (id=submit_btn) and it's submit action. HTML: <div id="loginButton" > </div> <input type="submit" style="display:none" name="submit" id="submit_btn" /> And JQuery: $(document).ready(function() { $('#loginButton').click(function() { $('#LoginForm').submit(); }); $("form[action$='HandleLoginForm']").submit(function() { Login(); return false; }); return false; }); Function Login() is working with Ajax, without downloading file dialog, but I need also auto complete passwords dialog. function Login() { var urlData = $("#LoginForm").serialize(); if (returnUrl != "") { urlData = $("#LoginForm").serialize() + "&returnUrl=" + returnUrl; } $.ajax({ url: $("#LoginForm").attr("action"), type: "POST", data: urlData, dataType: "json", success: function(result) { if (result.Content != null) { if (result.Valid) { window.location = result.Content.toString(); } else { document.body.innerHTML = result.Content.toString(); } } } }); return false; } It is easy when you use only <input type="submit"> instead of DIV. Form knows that it is for auto completing passwords, but if I use div and force hidden button click like in the code from below, it doesn't show autocomplete password dialog. $('#submit_btn').click(); It will not work. User is logged in, but no reminding for browser to store password. I need this.

  • Is it possible to unstick a remote IIS ASP server after an exception hangs the session?

    - by user89691
    I have been coding an app in classic ASP that accesses 2 Access databases. I had a page I was working on throw an exception, which is normal during development and causes no lasting problems. This time however, after the exception any attempt to open either of the databases would freeze the session with an infinite script timeout. If I delete the session cookie I an able to access ASP pages again until I try to open the database again. The database that was open when the exception was thrown is left open. There is a LDB lock file and I can't rename or delete either the LDB or MDB file, though I can download the MDB file with FTP. The 2nd access database is not open but any attempt to read this also hangs the session. Accessing HTML pages is fine. The site is hosted with Hostway and they are not interested ("Coding problem = Your problem" even though it leaves my site dead in the water, I suspect until the next reboot, whenever that might be). Here is the dump from the relevant ASP page that threw the exception: Active Server Pages error 'ASP 0115' Unexpected error /translatestats.asp A trappable error (C0000005) occurred in an external object. The script cannot continue running. Active Server Pages error 'ASP 0240' Script Engine Exception /translatestats.asp A ScriptEngine threw exception 'C0000005' in 'IActiveScript::Close()' from 'CActiveScriptEngine::FinalRelease()'. Is there any way I can unstick the site / force close the database remotely ?

  • CSS doesn't apply to dynamically created elements in IE 7?

    - by Austin Hyde
    In the project I am working on, I dynamically generate (with javascript) filters that look like this: <div class="filter"> <a ... class="filter_delete_link">Delete</a> <div class="filter_field"> ... </div> <div class="filter_compare"> ... </div> <div class="filter_constraint"> ... </div> <div class="filter_logic"> ... </div> </div> And I have CSS that applies to each filter (for example): .filter a.filter_delete_link{ display:block; height:16px; background: url('../images/remove_16.gif') no-repeat; padding-left:20px; } However, it seems in IE 7 (and probably 6 for that matter), these styles don't get applied to the new filters. Everything works perfectly in Firefox/Chrome/IE8. Using the IE8 developer tools, set to IE7 mode, the browser can see the new elements, and can see the CSS, but just isn't applying the CSS. Is there a way to force IE to reload styles, or perhaps is there a better way to fix this?

  • Exception Handling in ASP.NET MVC and Ajax - [HandleException] filter

    - by Graham
    All, I'm learning MVC and using it for a business app (MVC 1.0). I'm really struggling to get my head around exception handling. I've spent a lot of time on the web but not found anything along the lines of what I'm after. We currently use a filter attribute that implements IExceptionFilter. We decorate a base controller class with this so all server side exceptions are nicely routed to an exception page that displays the error and performs logging. I've started to use AJAX calls that return JSON data but when the server side implementation throws an error, the filter is fired but the page does not redirect to the Error page - it just stays on the page that called the AJAX method. Is there any way to force the redirect on the server (e.g. a ASP.NET Server.Transfer or redirect?) I've read that I must return a JSON object (wrapping the .NET Exception) and then redirect on the client, but then I can't guarantee the client will redirect... but then (although I'm probably doing something wrong) the server attempts to redirect but then gets an unauthorised exception (the base controller is secured but the Exception controller is not as it does not inherit from this) Has anybody please got a simple example (.NET and jQuery code). I feel like I'm randomly trying things in the hope it will work Exception Filter so far... public class HandleExceptionAttribute : FilterAttribute, IExceptionFilter { #region IExceptionFilter Members public void OnException(ExceptionContext filterContext) { if (filterContext.ExceptionHandled) { return; } filterContext.Controller.TempData[CommonLookup.ExceptionObject] = filterContext.Exception; if (filterContext.HttpContext.Request.IsAjaxRequest()) { filterContext.Result = AjaxException(filterContext.Exception.Message, filterContext); } else { //Redirect to global handler filterContext.Result = new RedirectToRouteResult(new RouteValueDictionary(new { controller = AvailableControllers.Exception, action = AvailableActions.HandleException })); filterContext.ExceptionHandled = true; filterContext.HttpContext.Response.Clear(); } } #endregion private JsonResult AjaxException(string message, ExceptionContext filterContext) { if (string.IsNullOrEmpty(message)) { message = "Server error"; //TODO: Replace with better message } filterContext.HttpContext.Response.StatusCode = (int)HttpStatusCode.InternalServerError; filterContext.HttpContext.Response.TrySkipIisCustomErrors = true; //Needed for IIS7.0 return new JsonResult { Data = new { ErrorMessage = message }, ContentEncoding = Encoding.UTF8, }; } }

  • Close application on error

    - by poke
    I’m currently writing an application for the Android platform that requires a mounted SD card (or ExternalStorage). I know that it might not be the best way to require something like that, but the application will work with quite a lot of data, and I don’t even want to think about storing that on the device’s storage. Anyway, to ensure that the application won’t run without the external storage, I do a quick check in the activity’s onCreate method. If the card is not mounted, I want to display an error message and then quit the application. My current approach looks like this: public void onCreate ( Bundle savedInstanceState ) { super.onCreate( savedInstanceState ); setContentView( R.layout.main ); try { // initialize data storage // will raise an exception if it fails, or the SD card is not mounted // ... } catch ( Exception e ) { AlertDialog.Builder builder = new AlertDialog.Builder( this ); builder .setMessage( "There was an error: " + e.getMessage() ) .setCancelable( false ) .setNeutralButton( "Ok.", new DialogInterface.OnClickListener() { public void onClick ( DialogInterface dialog, int which ) { MyApplication.this.finish(); } } ); AlertDialog error = builder.create(); error.show(); return; } // continue ... } When I run the application, and the exception gets raised (I raise it manually to check if everything works), the error message is displayed correctly. However when I press the button, the application closes and I get an Android error, that the application was closed unexpectedly (and I should force exit). I read some topics before on closing an application, and I know that it maybe shouldn’t happen like that. But how should I instead prevent the application from continuing to run? How do you close the application correctly when an error occurs?

  • Http Digest Authentication, Handle different browser char-sets...

    - by user160561
    Hi all, I tried to use the Http Authentication Digest Scheme with my php (apache module) based website. In general it works fine, but when it comes to verification of the username / hash against my user database i run into a problem. Of course i do not want to store the user´s password in my database, so i tend to store the A1 hashvalue (which is md5($username . ':' . $realm . ':' . $password)) in my db. This is just how the browser does it too to create the hashes to send back. The Problem: I am not able to detect if the browser does this in ISO-8859-1 fallback (like firefox, IE) or UTF-8 (Opera) or whatever. I have chosen to do the calculation in UTF-8 and store this md5 hash. Which leads to non-authentication in Firefox and IE browsers. How do you solve this problem? Just do not use this auth-scheme? Or Store a md5 Hash for each charset? Force users to Opera? (Terms of A1 refer to the http://php.net/manual/en/features.http-auth.php example.) (for digest access authentication read the according wikipedia entry)

  • .Net xsd.exe tool doesn't generate all types

    - by Mrchief
    For some reason, MS .Net (v3.5) tool - xsd.exe doesn't generate types when they are not used inside any element. e.g. XSD File (I threw in the complex element to avoid this warning - "Warning: cannot generate classes because no top-level elements with complex type were found."): <?xml version="1.0" encoding="utf-8"?> <xs:schema targetNamespace="http://tempuri.org/XMLSchema.xsd" elementFormDefault="qualified" xmlns="http://tempuri.org/XMLSchema.xsd" xmlns:mstns="http://tempuri.org/XMLSchema.xsd" xmlns:xs="http://www.w3.org/2001/XMLSchema" > <xs:simpleType name="EnumTest"> <xs:restriction base="xs:string"> <xs:enumeration value="item1" /> <xs:enumeration value="item2" /> <xs:enumeration value="item3" /> </xs:restriction> </xs:simpleType> <xs:complexType name="myComplexType"> <xs:attribute name="Name" use="required" type="xs:string"/> </xs:complexType> <xs:element name="myElem" type="myComplexType"></xs:element> </xs:schema> When i run this thru xsd.exe using xsd /c xsdfile.xsd I don't see EnumTest in the generated cs file. Note; Even though I don't use the enum here, but in my actual project, I have cases like this where we send enum's string value as output. How can I force the xsd tool to include these? Or should I switch to some other tool? I work in Visual Studio 2008.

  • 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 ?!

  • How to open AsyncTask from a Thread

    - by Abhishek
    In my application I have created a SplashScreen that will b shown for 5 Seconds and after that it executes an if else case depending upon the values stored in the Preference file. If Preference file contains values then the AsyncTask code will run else the Login form will load. When i try to run my application. The thread is going to the Login form with the help of intent but when it comes to AsyncTask my application shows a force close error message. This is my SplashScreen code: public class SplashScreen extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.splashscreen); Thread timer = new Thread() { public void run() { try { sleep(5000); } catch(InterruptedException e) { e.printStackTrace(); } finally { if(GoGolfPref.getEmail(SplashScreen.this)!=null && GoGolfPref.getPass(SplashScreen.this)!=null) { new LoadingScreen(SplashScreen.this, SplashScreen.this).execute("login_page", Login.url+GoGolfPref.getEmail(SplashScreen.this)+"/"+GoGolfPref.getPass(SplashScreen.this)); } else { Intent in = new Intent(SplashScreen.this, Login.class); startActivity(in); finish(); } } } }; timer.start(); } } This is the error I am getting: 08-29 07:25:58.040: E/AndroidRuntime(2365): FATAL EXCEPTION: Thread-10 08-29 07:25:58.040: E/AndroidRuntime(2365): java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare() 08-29 07:25:58.040: E/AndroidRuntime(2365): at android.os.Handler.<init>(Handler.java:121) 08-29 07:25:58.040: E/AndroidRuntime(2365): at android.app.Dialog.<init>(Dialog.java:101) 08-29 07:25:58.040: E/AndroidRuntime(2365): at android.app.AlertDialog.<init>(AlertDialog.java:63) 08-29 07:25:58.040: E/AndroidRuntime(2365): at android.app.ProgressDialog.<init>(ProgressDialog.java:80) 08-29 07:25:58.040: E/AndroidRuntime(2365): at android.app.ProgressDialog.<init>(ProgressDialog.java:76) 08-29 07:25:58.040: E/AndroidRuntime(2365): at com.pnf.gogolf.LoadingScreen.<init>(LoadingScreen.java:130) 08-29 07:25:58.040: E/AndroidRuntime(2365): at com.pnf.gogolf.SplashScreen$1.run(SplashScreen.java:32) How to get this working?

  • Design problem with callback functions in android

    - by Franz Xaver
    Hi folks! I'm currently developing an app in android that is accessing wifi values, that is, the application needs to scan for all access point and their specific signal strengths. I know that I have to extend the class BroadcastReceiver overwriting the method BroadcastReceiver.onReceive(Context context, Intent intent) which is called when the values are ready. Perhaps there exist solutions provided by the android system itself but I'm relatively new to android so I could need some help. The problem I encountered is that I got one class (an activity, thus controlled by the user) that needs this scan results for two different things (first to save the values in a database or second, to use them for further calculations but not both at one moment!) So how to design the callback system in order to "transport" the scan results from onReceive(Context context, Intent intent) to the operation intended by the user? My first solution was to define enums for each use case (save or use for calculations) which wlan-interested classes have to submit when querying for the values. But that would force the BroadcastReceiverextending class to save the current enum and use it as a parameter in the callback function of the querying class (this querying class needs to know what it asked for when getting backcalled) But that seems to me kind of dirty ;) So anyone a good idea for this?

  • How best to implement "favourites" feature? (like favourite products on a data driven website)

    - by ClarkeyBoy
    Hi, I have written a dynamic database driven, object oriented website with an administration frontend etc etc. I would like to add a feature where customers can save items as "favourites", without having to create an account and login, to come back to them later, but I dont know how exactly to go about doing this... I see three options: Log favourites based on IP address and then change these to be logged against an account if the customer then creates an account; Force customers to create an account to be able to use this functionality; Log favourites based on IP address but give users the option to save their favourites under a name they specify. The problem with option 1 is that I dont know much about IP addresses - my Dad thinks they are unique, but I know people have had problems with systems like this. The problem with 1 and 2 is that accounts have not been opened up to customers yet - only administrators can log in at the moment. It should be easy to alter this (no more than a morning or afternoons work) but I would also have to implement usergroups too. The problem with option 3 is that if user A saves a favourites list called "My Favourites", and then user B tries to save a list under this name and it is refused, user B will then be able to access the list saved by user A because they now know it already exists. A solution to this is to password protect lists, but to go to all this effort I may as well implement option 2. Of course I could always use option 4; use an alternative if anyone can suggest a better solution than any of the above options. So has anyone ever done something like this before? If so how did you go about it? What do you recommend (or not recommend)? Many thanks in advance, Regards, Richard

  • How to prevent multiple registrations?

    - by GG.
    I develop a political survey website where anyone can vote once. Obviously I have to prevent multiple registrations for the survey remains relevant. Already I force every user to login with their Google, Facebook or Twitter account. But they can authenticate 3 times if they have an account on each, or authenticate with multiple accounts of the same platform (I have 3 accounts on Google). So I thought also store the IP address, but they can still go through a proxy... I thought also keep the HTTP User Agent with PHP's get_browser(), although they can still change browsers. I can extract the OS with a regex, to change OS is less easier than browsers. And there is also geolocation, for example with the Google Map API. So to summarize, several ideas: 1 / SSO Authentication (I keep the email) 2 / IP Address 3 / HTTP User Agent 4 / Geolocation with an API Have you any other ideas that I did not think? How to embed these tests? Execute in what order? Have you already deploy this kind of solution?

  • PHP: Exception not caught by try ... catch

    - by Christian Brenner
    I currently am working on an autoloader class for one of my projects. Below is the code for the controller library: public static function includeFileContainingClass($classname) { $classname_rectified = str_replace(__NAMESPACE__.'\\', '', $classname); $controller_path = ENVIRONMENT_DIRECTROY_CONTROLLERS.strtolower($classname_rectified).'.controller.php'; if (file_exists($controller_path)) { include $controller_path; return true; } else { // TODO: Implement gettext('MSG_FILE_CONTROLLER_NOTFOUND') throw new Exception('File '.strtolower($classname_rectified).'.controller.php not found.'); return false; } } And here's the code of the file I try to invoke the autoloader on: try { spl_autoload_register(__NAMESPACE__.'\\Controller::includeFileContainingClass'); } catch (Exception $malfunction) { die($malfunction->getMessage()); } // TESTING ONLY $test = new Testing(); When I try to force a malfunction, I get the following message: Fatal error: Uncaught exception 'Exception' with message 'File testing.controller.php not found.' in D:\cerophine-0.0.1-alpha1\application\libraries\controller.library.php:51 Stack trace: #0 [internal function]: application\Controller::includeFileContainingClass('application\Tes...') #1 D:\cerophine-0.0.1-alpha1\index.php(58): spl_autoload_call('application\Tes...') #2 {main} thrown in D:\cerophine-0.0.1-alpha1\application\libraries\controller.library.php on line 51 What seems to be wrong?
