  • Gtk+ Tables for Layout - Good or Bad?

    - by wag2639
    Hi, I'm just starting to play around with GTK+ and I wanted to stop bad habits before they happen. I see that GTK+ seems to be a little based in HTML/CSS and I was wondering if there are any reasons to avoid using tables for layout.

  • Learning XNA for Game Development. Is it worth It?

    - by Nipuna Silva
    It seems that most of the popular games in the world are developed using C++. But Microsoft's game platform, XNA Studio is based on programming in C# and I didn't find any popular game which was developed using XNA. Also there are fewer Ebooks you find on XNA and even the google search for a problem won't give you much help. Does people doesn't use XNA as a gaming platform? Is it worth learning XNA for game development or should I consider some other platform?

  • Which mobile operating system should I code for?

    - by samgoody
    It seems as though mobile computing has fully arrived. I would like to rewrite two of our programs for mobile devices, but am a bit lost as to which platform to target. Complicating this decision: I would need to learn the relevant languages and IDEs - my coding to date has been almost all web based (PHP, JS, Actionscript, etc. Some ASPX). Most users seem to be religious about their mobile decision, so oral conversations leave me more confused then enlightened. I do not yet own a smartphone - will have to buy one once I know which platform to be aiming for. Both of my programs are more for business users, (one is only useful for C.P.A.s). I am a single developer, and cannot develop for more than one platform at a time. Getting it right is important. Based on what I've found on the web, I would've expected RIM to be a shoo-in, and the general order to be as follows: RIM Blackberry - More of them than any other brand. Despite naysayers, they've had double the sales (or perhaps 5X the sales) of any other smartphone, and have continued to grow. And, they have business users. Android - According to Schmidt, they have outsold everyone else except RIM (though I can't find where I read that now), and they are just getting started. According to Comscore, they are already at 8% of the market and expected to hit Shcmidt's claims within six months. Nokia - The largest worldwide. If they would just make up between Maemo or Symbian, I would be far less confused. iPhone - Much more competition by other apps, fewer sales to be had, and a overlord that can delay or cancel my app at any time. Is Cocoa hard to learn? Windows Mobile - Word is that version 7 will not be backwards compatible and losing market share. Palm WebOS - Perhaps this should go first, as it is the only one that offers tools to make my life easy as a web application developer. No competition in marketplace. But not very many users either. However, a search on StackOverflow shows a hugely disproportionate number of iPhone questions versus Blackberry. Likewise, there are clearly more apps on iPhone, so it must be getting developer love. What is the one platform I should develop for? Please back up your answer with the logic.

  • How do I test an image alt value using capybara?

    - by stayce
    I'm trying to define a step to test the value of alt text of an image using capybara and the css selectors. I wrote one for input values based on the readme examples: Then /^I should see a value of "([^\"])" within the "([^\"])" input$/ do |input_value, input_id| element_value = locate("input##{input_id}").value element_value.should == input_value end But I can't figure this one out...something like: Then /^I should see the alttext "([^\"]*)"$/ do | alt_text | element_value = locate("img[alt]").value Anyone know how I can locate the alt text value?

  • Sqlite table constraint - unique on multiple columns

    - by Rich
    I can find syntax "charts" on this on the sqlite website, but no examples and my code is crashing.

This is what I have that is causing a SQLiteException with the message "syntax error". CREATE TABLE name (column defs) UNIQUE (col_name1, col_name2) ON CONFLICT REPLACE I'm doing this based on the following: table-constraint

  • Rails app w/ 2.2.0 embedd how to use ruby 1.8 vice 1.9

    - by Barb
    Hello all, I have just downloaded an app that is based on Rail 2.2.0 which is included in the app. I have just upgraded to Ruby 1.9 and I still have Ruby 1.8 on my machine. Is there a way I can tell this app to use Ruby 1.8 vice 1.9? Would it be easier to decouple the app from Rails 2.2.0 and upgrade it to Rails 2.3.6? If changing the rails would be easier, how do I do that?

  • SharePoint 2010 Custom WCF Service - Windows and FBA Authentication

    - by e-rock
    I have SharePoint 2010 configured for Claims Based Authentication with both Windows and Forms Based Authentication (FBA) for external users. I also need to develop custom WCF Services. The issue is that I want Windows credentials passed into the WCF Service(s); however, I cannot seem to get the Windows credentials passed into the services. My custom WCF service appears to be using Anonymous authentication (which has to be enabled in IIS in order to display the FBA login screen). The example I have tried to follow is found at http://msdn.microsoft.com/en-us/library/ff521581.aspx. The WCF service gets deployed to _vti_bin (ISAPI folder). Here is the code for the .svc file <%@ ServiceHost Language="C#" Debug="true" Service="MyCompany.CustomerPortal.SharePoint.UI.ISAPI.MyCompany.Services.LibraryManagers.LibraryUploader, $SharePoint.Project.AssemblyFullName$" Factory="Microsoft.SharePoint.Client.Services.MultipleBaseAddressBasicHttpBindingServiceHostFactory, Microsoft.SharePoint.Client.ServerRuntime, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" CodeBehind="LibraryUploader.svc.cs" %> Here is the code behind for the .svc file [ServiceContract] public interface ILibraryUploader { [OperationContract] string SiteName(); } [BasicHttpBindingServiceMetadataExchangeEndpoint] [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)] public class LibraryUploader : ILibraryUploader { //just try to return site title right now… public string SiteName() { WindowsIdentity identity = ServiceSecurityContext.Current.WindowsIdentity; ClaimsIdentity claimsIdentity = new ClaimsIdentity(identity); return SPContext.Current.Web.Title; } } The WCF test client I have just to test it out (WPF app) uses the following code to call the WCF service... private void Button1Click(object sender, RoutedEventArgs e) { BasicHttpBinding binding = new BasicHttpBinding(); binding.Security.Mode = BasicHttpSecurityMode.TransportCredentialOnly; binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Ntlm; EndpointAddress endpoint = new EndpointAddress( "http://dev.portal.data-image.local/_vti_bin/MyCompany.Services/LibraryManagers/LibraryUploader.svc"); LibraryUploaderClient libraryUploader = new LibraryUploaderClient(binding, endpoint); libraryUploader.ClientCredentials.Windows.AllowedImpersonationLevel = System.Security.Principal.TokenImpersonationLevel.Impersonation; MessageBox.Show(libraryUploader.SiteName()); } I am somewhat inexperienced with IIS security settings/configurations when it comes to Claims and trying to use both Windows and FBA. I am also inexperienced when it comes to WCF configurations for security. I usually develop internal biz apps and let Visual Studio decide what to use because security is rarely a concern.

  • Is it possible to configure a Spring session scoped bean with attributes from the session?

    - by Dave G
    I'm trying to create a service bean that when referenced will be initialized with HttpSession based attributes. Let's say for sake of argument that my webapp would do the following: Establish a session Request login & password When service is requested (it is scope="session" and has init-method="init()") a new instance is created for the session. In the init method, can I reference the HttpSession either through passing it in as a parameter and referencing it by EL? Any ideas on this would be appreciated.

  • Quick top level server language question.

    - by Shane
    Right, so if you have to decide on a server-side language for a distributed Linux-based server backend, would you choose: PHP Mono ASP.net Java As a C++ programmer, I'm thinking Java+Tomcat, but I'd love to hear experienced thoughts here, especially relating to debugging and IDE (likely Eclipse). Also, please, it's not a flame question. I'm seeing excellent sites written in all, I'm just thinking about the compile/debug/release cycle. Cheers, Shane

  • Is there a way to change the map data for the Android Google Map API?

    - by Mannaz
    I need to use a different datasource inside a map in Android than the google provided data. Is there a way to change the datasource to a tile based service (openstreetmap.org for example)? Or are there other Android map APIs which are OpenSource and can be adapted (except Ericcson Mobile Maps - this doesn't work for me because of the licence)? It doesent have to have a server side part - a rich function library would be enough.

  • SonarJ like tool for .NET

    - by J. Random Coder
    I'm looking for a tool like SonarJ but for .NET instead of Java. SonarJ helps you to find deviations between he architecture and the code within minutes. It can be integrated into your IDE to help you avoid the introduction of new architetural violations to your code base. You can also use it to maintain metric based software quality rules which will keep complexity under control. I googled and searched SO without satisfying results.
