Android: "Edit Source Lookup Path...".

I am developing on a Mac with Eclipse and have the skeleton for an app that implements the standard framework callbacks (onCreate, onDestroy, onPause, etc..). When I set breakpoints in the callbacks the debugger stops and displays a tab that says "ActivityThread.performLaunchActivity(ActivityThread $ActivityRecord,Intent)line:2477" and in the tab page body there is some red text that says "Source not found" and a button that says "Edit Source Lookup Path...". I have tried adding several paths via "Edit Source Lookup Path..." but can't see to find the one Eclipse is looking for. Can anyone point me in the right direction?

How do I set a dependency on Spring Web Services in my POM.xml

- by Ben

I get this on a lot of Maven dependencies, though current source of pain is Spring. I'll set a Spring version and include it like so: <spring-version>3.0.0.RELEASE</spring-version>  <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring-version}</version> </dependency> Which works as expected. I am however having problems setting my dependency on spring-ws-core for web services. The latest I can find in any repo is 2.0.0-M1. http://mvnrepository.com/artifact/org.springframework.ws/spring-ws-core Any clues on what I need to include in my maven POM to get Spring 3 web services to work :)

Problem running ASP.NET MVC 2 website on IIS7

- by Charlie

I'm trying to deploy my ASP.NET MVC 2 website from VS2010 beta 2 to IIS7. The publish works fine but none of the routes work, so when I go to the URL http://localhost/myapp/Home/Index I get the error: HTTP Error 404.0 - Not Found The resource you are looking for has been removed, had its name changed, or is temporarily unavailable. I'm deploying to a virtual directory which is using an app pool configured for the .NET 4 framework with managed pipeline mode set to integrated. Also, if I go Basic Settings-Test Connection, both tests pass. From what I understand, it should just work? I don't have any problems deploying Nerd Dinner from VS2008, that works fine.

How to generate Doctrine models/classes that extend a custom record class

- by Shane O'Grady

When I use Doctrine to generate classes from Yaml/db each Base class (which includes the table definition) extends the Doctrine_Record class. Since my app uses a master and (multiple) slave db servers I need to be able to make the Base classes extend my custom record class to force writes to go to the master db server (as described here). However if I change the base class manually I lose it again when I regenerate my classes from Yaml/db using Doctrine. I need to find a way of telling Doctrine to extend my own Base class, or find a different solution to a master/slave db setup using Doctrine. Example generated model: abstract class My_Base_User extends Doctrine_Record { However I need it to be automatically generated as: abstract class My_Base_User extends My_Record { I am using Doctrine 1.2.1 in a new Zend Framework 1.9.6 application if it makes any difference.

Data-related security Implementation

- by devdude

Using Shiro we have a great security framework embedded in our enterprise application running on GF. You define users, roles, permissions and we can control at any fine-grain level if a user can access the application, a certain page or even click a specific button. Is there a recipe or pattern, that allows on top of that, to restrict a user from seeing certain data ? Sample: You have a customer table for 3 factories (part of one company). An admin user can see all customer records, but the user at the local factory must not see any customer data of other factories (for whatever reason). Te security feature should be part of the role definition. Thanks for any input and ideas

block certain websites from browser

- by phunehehe

Hello there, A friend of mine (who is not a geek) asks me how to stop her little brother from playing web games on her computer. She is currently using Chrome and IE, and I have never done that before, even on FF. I would prefer a solution that is simple and does not require additional applications. Although it seems unlikely, is there a solution that works for all browsers (i.e. do it once and I never have to fix it for a new browser)? Thanks.

Unecrypted Image of Truecrypt-Encrypted System Partition

- by Dexter

The general tenor around the internet seems to be that you can't create images of system partitions that have been encrypted (with truecrypt) other than with dd or similar sector-by-sector copy tools. These files however are very impractical given their size (and are obviously incompressible) which makes keeping multiple states/backups of your system partition rather expensive (..especially considering current hdd prices). The problem is that backup tools (like Acronis True Image, Clonezilla, etc.) won't give you the option to create an image of (mounted/opened) Truecrypt partitions, or that there is no recovery environment for restoring the backup, that would allow to run truecrypt before doing any actual restoring. After some trial and error however, I believe I have found a very simple way. Since Truecrypt (running in Linux) creates a virtual block device, that it uses for mounting the unencrypted partitions into the file system, partclone can be used for creating/restoring images. What I did: boot up a linux live disk mount/open the drive/device/partition in truecrypt unmount the filesystem mount point again, like so: umount /media/truecryptX ("X" being the partition number assigend by truecrypt) use partclone (this is what clonezilla would do too, except that clonezilla only offers you to back up real drive partitions, not virtual block devices): partclone.ntfs -c -s /dev/mapper/truecryptX -o nameOfBackupFile for restoring steps 1-3 remain the same, and step 4 is partclone.ntfs -r -s nameOfBackupFile -o /dev/mapper/truecryptX A backup and test-restore of the system (with this method) seems to have worked fine (and the changed settings were reverted to the backup-state). The backup file is ~40 GB (and compressible down to <8GB with 7zip/LZMA2 on the "fast" setting). I can't quite believe that I'm the only one that wants to create images of encrypted drives, but doesn't want to waste 100GB on the backup of one single system state. So my question now is, given how simple this was, and that no one seems to mention anywhere that this is possible - did I miss something? or did I do something wrong? Is there any situation that I didn't think of where this method will fail? Obviously, the backup file needs to be stored in some other encrypted place in order to still remain confidential, since it is unencrypted. Also, in order to do a full "bare metal" restore, one would have to actually first (re-)install Windows, encrypt it, and only then restore the backup file. The funny thing however is that you won't need to backup any partition tables, etc. since the reinstall will effectively take care of that. Is there anything else? This is imho still a lot better than having sector-by-sector images..

Easy way to apply Joomla template styling to my own content

- by Joey Adams

I have an application that is mainly a bunch of PHP files included in a Joomla! application by Jumi. I want to make the site look nicer, but I'd rather not reinvent the wheel. There is a RocketTheme template installed on the site, and I'd like to be able to leverage it or some of the other CSS used alongside it. Specifically, I want to decorate tables. Should I search for and include CSS classes directly into my tags by searching through the template's classes, or is there a framework I could use that automatically adds the right classes based on the current theme?

Objectdatasource and Gridview : Sorting, paging, filtering

- by Simon

Hi there, Im using entity framework 1.0 and trying to feed out a Gridview with a objectdatasource that have access to my facade. The problem is, that it seems to be particulary difficult and haven't seen anything that realy do what i want it to do on the internet. For those who know, a gridview feeded with an objectdatasource, it can't sort automaticaly then you must do it manually. It's not that bad. Where it becomes a nightmare, its when we add paging and filter settings to a gridview's datasource. After many hours searching on the internet, i'm asking you, guys, if anyone knows a link that can explain me how to mix Pagging, Sorting and filtering for a gridview and an objectdatasource! Thanks in advance and sorry for my english.

Why does calling IEnumerable<string>.Count() create an additional assembly dependency ?

- by Gishu

Assume this chain of dll references Tests.dll >> Automation.dll >> White.Core.dll with the following line of code in Tests.dll, where everything builds result.MissingPaths Now when I change this to result.MissingPaths.Count() I get the following build error for Tests.dll "White.UIItem is not defined in an assembly that is not referenced. You must add a reference to White.Core.dll." And I don't want to do that because it breaks my layering. Here is the type definition for result, which is in Automation.dll public class HasResult { public HasResult(IEnumerable<string> missingPaths ) { MissingPaths = missingPaths; } public IEnumerable<string> MissingPaths { get; set; } public bool AllExist { get { return !MissingPaths.Any(); } } } Down the call chain the input param to this ctor is created via (The TreeNode class is in White.Core.dll) assetPaths.Where(assetPath => !FindTreeNodeUsingCache(treeHandle, assetPath)); Why does this dependency leak when calling Count() on IEnumerable ? I then suspected that lazy evaluation was causing this (for some reason) - so I slotted in an ToArray() in the above line but didn't work. Update 2011 01 07: Curiouser and Curiouser! it won't build until I add a White.Core reference. So I add a reference and build it (in order to find the elusive dependency source). Open it up in Reflector and the only references listed are Automation, mscorlib, System.core and NUnit. So the compiler threw away the White reference as it was not needed. ILDASM also confirms that there is no White AssemblyRef entry. Any ideas on how to get to the bottom of this thing (primarily for 'now I wanna know why' reasons)? What are the chances that this is an VS2010/MSBuild bug? Update 2011 01 07 #2 As per Shimmy's suggestion, tried calling the method explcitly as an extension method Enumerable.Count(result.MissingPaths) and it stops cribbing (not sure why). However I moved some code around after that and now I'm getting the same issue at a different location using IEnumerable - this time reading and filtering lines out of a file on disk (totally unrelated to White). Seems like it's a 'symptom-fix'. var lines = File.ReadLines(aFilePath).ToArray(); once again, if I remove the ToArray() it compiles again - it seems that any method that causes the enumerable to be evaluated (ToArray, Count, ToList, etc.) causes this. Let me try and get a working tiny-app to demo this issue... Update 2011 01 07 #3 Phew! More information.. It turns out the problem is just in one source file - this file is LINQ-phobic. Any call to an Enumerable extension method has to be explicitly called out. The refactorings that I did caused a new method to be moved into this source file, which had some LINQ :) Still no clue as to why this class dislikes LINQ. using System; using System.Collections.Generic; using System.IO; using System.Linq; using G.S.OurAutomation.Constants; using G.S.OurAutomation.Framework; using NUnit.Framework; namespace G.S.AcceptanceTests { public abstract class ConfigureThingBase : OurTestFixture { .... private static IEnumerable<string> GetExpectedThingsFor(string param) { // even this won't compile - although it compiles fine in an adjoining source file in the same assembly //IEnumerable<string> s = new string[0]; //Console.WriteLine(s.Count()); // this is the line that is now causing a build failure // var expectedInfo = File.ReadLines(someCsvFilePath)) // .Where(line => !line.StartsWith("REM", StringComparison.InvariantCultureIgnoreCase)) // .Select(line => line.Replace("%PLACEHOLDER%", param)) // .ToArray(); // Unrolling the LINQ above removes the build error var expectedInfo = Enumerable.ToArray( Enumerable.Select( Enumerable.Where( File.ReadLines(someCsvFilePath)), line => !line.StartsWith("REM", StringComparison.InvariantCultureIgnoreCase)), line => line.Replace("%PLACEHOLDER%", param)));

ezpublish for practical e-commerce?

- by Olaseni

For while now I have been using ezpublish as a framework, and CMS when my web projects are based on PHP, and I must say, I have grown accustomed to it because of its flexibility for most scenarios. However, I've had to build e-commerce sites now and then, and ezpublish includes a webshop that caters for the e-commerce needs of your installation, and of-course with all the tools you need to extend, should you need to. Is it worthwhile and optimal to use the inbuilt webshop for an e-commerce solution, or should I rather go with an all out e-commerce solution like Magento, which has made a significant impact in that sector?

Detecting when Bluetooth is disabled on iOS5

- by Non Umemoto

I'm developing blog speaker app. I wanna pause the audio when bluetooth is disabled like iPod app. I thought it's not possible without using private api after reading this. Check if Bluetooth is Enabled? But, my customer told me that Rhapsody and DI Radio apps both support it. Then I found iOS5 has Core Bluetooth framework. https://developer.apple.com/library/ios/documentation/CoreBluetooth/Reference/CoreBluetooth_Framework/CoreBluetooth_Framework.pdf CBCentralManagerStatePoweredOff status seems like the one. But, the description says this api only supports Bluetooth 4.0 low energy devices. Did anyone try doing the same thing? I want to support current popular bluetooth headsets, or bluetooth enabled steering wheel on the car. I don't know if it's worth trying when it only supports some brand new bluetooth.

IIS7 Modules - managed or native?

- by Simon Linder

Hi all, as the old ISAPI filters are going to die sooner or later, I want to rewrite an old ISAPI filter that was used in IIS 6 into a module for use in IIS 7. The module will be used globally, meaning it will be used within each site, on a Windows Server 2008 R2 with IIS 7.5 installed, that will host several thousand web sites and managing about 50 application pools. My question now is if I should write that module in managed or unmanaged code? One of my concerns regarding managed code is the massive memory consumption due to the .NET framework overhead. I don't know how this would effect the server's performance. I already wrote modules in managed as well as in unmanaged code. So this is not the bothering my decision. But I would prefer to write the module in C# if there are no huge drawbacks. Any suggestions about that issue?

Automatically generate buddy classes from model in C#

I use Linq to Sql (although this is equally applicable in Entity Framework) for my models, and I'm finding myself creating buddy classes for my models all the time. I find this time consuming and repetitive. Is there an easy way to automatically generate these buddy classes based on the models? Perhaps a visual studio macro? An example of a buddy class that I'd like to create: [MetadataType(typeof(PersonMetadata))] public partial class Person { } public class PersonMetadata { public object Id { get; set; } public object FirstName { get; set; } } Thanks in advance.

How to parse a string into a nullable int in C# (.NET 3.5)

- by Glenn Slaven

I'm wanting to parse a string into a nullable int in C#. ie. I want to get back either the int value of the string or null if it can't be parsed. I was kind of hoping that this would work int? val = stringVal as int?; But that won't work, so the way I'm doing it now is I've written this extension method public static int? ParseNullableInt(this string value) { if (value == null || value.Trim() == string.Empty) { return null; } else { try { return int.Parse(value); } catch { return null; } } } Is there a better way of doing this? EDIT: Thanks for the TryParse suggestions, I did know about that, but it worked out about the same. I'm more interested in knowing if there is a built-in framework method that will parse directly into a nullable int?
