  • How can I load style resources from a dynamically loaded Silverlight application (XAP)?

    - by Tom
    I've followed Tim Heuer's video for dynamically loading other XAP's (into a 'master' Silverlight application), as well as some other links to tweak the loading of resources and am stuck on the particular issue of loading style resources from within the dynamically loaded XAP (i.e. the contents of Assets\Styles.xaml). When I run the master/hosting applcation, it successfully streams the dynamic XAP and I can read the deployment info etc. and load the assembly parts. However, when I actuall try to create an instance of a form from the Dynamic XAP, it fails with Cannot find a Resource with the Name/Key LayoutRootGridStyle which is in it's Assets\Styles.xaml file (it works if I run it directly so I know it's OK). For some reason these don't show up as application resources - not sure if I've totally got the wrong end of the stick, or am just missing something? Code snippet below (apologies it's a bit messy - just trying to get it working first) ... '' # Here's the code that reads the dynamic XAP from the web server ... '' #... wCli = New WebClient AddHandler wCli.OpenReadCompleted, AddressOf OpenXAPCompleted wCli.OpenReadAsync(New Uri("MyTest.xap", UriKind.Relative)) '' #... '' #Here's the sub that's called when openread is completed '' #... Private Sub OpenXAPCompleted(ByVal sender As Object, ByVal e As System.Net.OpenReadCompletedEventArgs) Dim sManifest As String = New StreamReader(Application.GetResourceStream(New StreamResourceInfo(e.Result, Nothing), New Uri("AppManifest.xaml", UriKind.Relative)).Stream).ReadToEnd Dim deploymentRoot As XElement = XDocument.Parse(sManifest).Root Dim deploymentParts As List(Of XElement) = _ (From assemblyParts In deploymentRoot.Elements().Elements() Select assemblyParts).ToList() Dim oAssembly As Assembly = Nothing For Each xElement As XElement In deploymentParts Dim asmPart As AssemblyPart = New AssemblyPart() Dim source As String = xElement.Attribute("Source").Value Dim sInfo As StreamResourceInfo = Application.GetResourceStream(New StreamResourceInfo(e.Result, "application/binary"), New Uri(source, UriKind.Relative)) If source = "MyTest.dll" Then oAssembly = asmPart.Load(sInfo.Stream) Else asmPart.Load(sInfo.Stream) End If Next Dim t As Type() = oAssembly.GetTypes() Dim AppClass = (From parts In t Where parts.FullName.EndsWith(".App") Select parts).SingleOrDefault() Dim mykeys As Array If Not AppClass Is Nothing Then Dim a As Application = DirectCast(oAssembly.CreateInstance(AppClass.FullName), Application) For Each strKey As String In a.Resources.Keys If Not Application.Current.Resources.Contains(strKey) Then Application.Current.Resources.Add(strKey, a.Resources(strKey)) End If Next End If Dim objectType As Type = oAssembly.GetType("MyTest.MainPage") Dim ouiel = Activator.CreateInstance(objectType) Dim myData As UIElement = DirectCast(ouiel, UIElement) Me.splMain.Children.Add(myData) Me.splMain.UpdateLayout() End Sub '' #...

    I'm trying to get zc.buildout to install Gunicorn from source. Using the following configuration: [gunicorn] recipe = collective.recipe.distutils url = http://github.com/benoitc/gunicorn/tarball/master results in the following error: SystemError: ('Failed', '"/usr/bin/python" setup.py -q install --install- purelib="/mnt/hgfs/Projects/intranation/parts/site-packages" --install-platlib="/mnt/hgfs/Projects/intranation/parts/site-packages"') Providing a --install-dir or --prefix doesn't help. Is there a recipe for zc.buildout that downloads a tarball and installs it via easy_install or similar?

  • Log4net duplicate logging entires

    - by user210713
    I recently switched out log4net logging from using config files to being set up programmatically. This has resulted in the nhiberate entries getting repeated 2 or sometimes 3 times. Here's the code. It uses a string which looks something like this "logger1|debug,logger2|info" private void SetupLog4netLoggers() { IAppender appender = GetAppender(); SetupRootLogger(appender); foreach (string logger in Loggers) { CommaStringList parts = new CommaStringList(logger, '|'); if (parts.Count != 2) continue; AddLogger(parts[0], parts[1], appender); } log.Debug("Log4net has been setup"); } private IAppender GetAppender() { RollingFileAppender appender = new RollingFileAppender(); appender.File = LogFile; appender.AppendToFile = true; appender.MaximumFileSize = MaximumFileSize; appender.MaxSizeRollBackups = MaximumBackups; PatternLayout layout = new PatternLayout(PATTERN); layout.ActivateOptions(); appender.Layout = layout; appender.ActivateOptions(); return appender; } private void SetupRootLogger(IAppender appender) { Hierarchy hierarchy = (Hierarchy)LogManager.GetRepository(); hierarchy.Root.RemoveAllAppenders(); hierarchy.Root.AddAppender(appender); hierarchy.Root.Level = GetLevel(RootLevel); hierarchy.Configured = true; log.Debug("Root logger setup, level[" + RootLevel + "]"); } private void AddLogger(string name, string level, IAppender appender) { Logger logger = LogManager.GetRepository().GetLogger(name)as Logger; if (logger == null) return; logger.Level = GetLevel(level); logger.Additivity = false; logger.RemoveAllAppenders(); logger.AddAppender(appender); log.Debug("logger[" + name + "] added, level[" + level + "]"); } And here's an example of what we see in our logs... 2010-05-06 15:50:39,781 [1] DEBUG NHibernate.Impl.SessionImpl - running ISession.Dispose() 2010-05-06 15:50:39,781 [1] DEBUG NHibernate.Impl.SessionImpl - closing session 2010-05-06 15:50:39,781 [1] DEBUG NHibernate.AdoNet.AbstractBatcher - running BatcherImpl.Dispose(true) 2010-05-06 15:50:39,796 [1] DEBUG NHibernate.Impl.SessionImpl - running ISession.Dispose() 2010-05-06 15:50:39,796 [1] DEBUG NHibernate.Impl.SessionImpl - closing session 2010-05-06 15:50:39,796 [1] DEBUG NHibernate.AdoNet.AbstractBatcher - running BatcherImpl.Dispose(true) 2010-05-06 15:50:39,796 [1] DEBUG NHibernate.Impl.SessionImpl - running ISession.Dispose() 2010-05-06 15:50:39,796 [1] DEBUG NHibernate.Impl.SessionImpl - closing session 2010-05-06 15:50:39,796 [1] DEBUG NHibernate.AdoNet.AbstractBatcher - running BatcherImpl.Dispose(true) Any hints welcome.

  • breakdown c++ code size

    - by Evan Rogers
    I'm looking for a nice stackoverflow-style answer to the first question in this old blog post, which I'll repeat below: "I’d really like some tool (ideally, g++ based) that shows me what parts of compiled/linked code are generated from what parts of C++ source code. For instance, to see whether a particular template is being instantiated for hundreds of different types (fixable via a template specialization) or whether code is being inlined excessively, or whether particular functions are larger than expected."

  • Android Source Not Compilable?

    - by GuyNoir
    So I've been looking at code from various parts of the Android git, but when I try to load and compile many of them (camera, media player, etc) they reference classes and parts of the SDK that just aren't available even with my SDK version updated to 2.2. (for example the bitmap config option inNativeAlloc) Is there a reason that these are not in the SDK given out to developers?

  • Is there a JQuery DOM manipulator/CSS selector equivalent class in PHP?

    - by DKinzer
    I know that I can use DOMDocument and DOMXPath to manipulate XML files. But, I really love JQuery, and it would be great if there was something more like JQuery in the PHP world that I could use for sever side DOM manipulation. NOTE: I'm only interested here in how JQuery Selects and Manipulates the DOM, not all the other parts of JQuerry (I guess you can say just the Pop and the Sizzle parts).

    Would someone please explain to me what the below paragraph means? This is a snippet from "Design Patterns: Elements of Reusable OO software" Part of an object's interface may be characterized by one type, and other parts by other types. Two objects of the same type need only share parts of their interfaces. Interfaces can contain other interfaces as subsets. - Design Patterns - Elements of Reusable OO software, pg 13

  • Display "custom" view (various images, various text). Should I use UIWebView?

    - by aw
    First: No, none of the content should be loaded from the web. All content parts are shipped with the main bundle. I have n images and mass of text (including lists). Instead of building all view parts programmatically in objective-c if was thinking of using an UIWebView and build "only" the HTML dynamically. Does anything speaks against it? How does UIWebView work with local content? Links and resources welcome. Thanks

  • Automating XNA Performance Testing?

    - by Grofit
    I was wondering what peoples approaches or thoughts were on automating performance testing in XNA. Currently I am looking at only working in 2d, but that poses many areas where performance can be improved with different implementations. An example would be if you had 2 different implementations of spatial partitioning, one may be faster than another but without doing some actual performance testing you wouldn't be able to tell which one for sure (unless you saw the code was blatantly slow in certain parts). You could write a unit test which for a given time frame kept adding/updating/removing entities for both implementations and see how many were made in each timeframe and the higher one would be the faster one (in this given example). Another higher level example would be if you wanted to see how many entities you can have on the screen roughly without going beneath 60fps. The problem with this is to automate it you would need to use the hidden form trick or some other thing to kick off a mock game and purely test which parts you care about and disable everything else. I know that this isnt a simple affair really as even if you can automate the tests, really it is up to a human to interpret if the results are performant enough, but as part of a build step you could have it run these tests and publish the results somewhere for comparison. This way if you go from version 1.1 to 1.2 but have changed a few underlying algorithms you may notice that generally the performance score would have gone up, meaning you have improved your overall performance of the application, and then from 1.2 to 1.3 you may notice that you have then dropped overall performance a bit. So has anyone automated this sort of thing in their projects, and if so how do you measure your performance comparisons at a high level and what frameworks do you use to test? As providing you have written your code so its testable/mockable for most parts you can just use your tests as a mechanism for getting some performance results... === Edit === Just for clarity, I am more interested in the best way to make use of automated tests within XNA to track your performance, not play testing or guessing by manually running your game on a machine. This is completely different to seeing if your game is playable on X hardware, it is more about tracking the change in performance as your game engine/framework changes. As mentioned in one of the comments you could easily test "how many nodes can I insert/remove/update within QuadTreeA within 2 seconds", but you have to physically look at these results every time to see if it has changed, which may be fine and is still better than just relying on playing it to see if you notice any difference between version. However if you were to put an Assert in to notify you of a fail if it goes lower than lets say 5000 in 2 seconds you have a brittle test as it is then contextual to the hardware, not just the implementation. Although that being said these sort of automated tests are only really any use if you are running your tests as some sort of build pipeline i.e: Checkout - Run Unit Tests - Run Integration Tests - Run Performance Tests - Package So then you can easily compare the stats from one build to another on the CI server as a report of some sort, and again this may not mean much to anyone if you are not used to Continuous Integration. The main crux of this question is to see how people manage this between builds and how they find it best to report upon. As I said it can be subjective but as knowledge will be gained from the answers it seems a worthwhile question.

  • Conflict Minerals - Design to Compliance

    - by C. Chadwick
    Dr. Christina  Schröder - Principal PLM Consultant, Enterprise PLM Solutions EMEA What does the Conflict Minerals regulation mean? Conflict Minerals has recently become a new buzz word in the manufacturing industry, particularly in electronics and medical devices. Known as the "Dodd-Frank Section 1502", this regulation requires SEC listed companies to declare the origin of certain minerals by 2014. The intention is to reduce the use of tantalum, tungsten, tin, and gold which originate from mines in the Democratic Republic of Congo (DRC) and adjoining countries that are controlled by violent armed militia abusing human rights. Manufacturers now request information from their suppliers to see if their raw materials are sourced from this region and which smelters are used to extract the metals from the minerals. A standardized questionnaire has been developed for this purpose (download and further information). Soon, even companies which are not directly affected by the Conflict Minerals legislation will have to collect and maintain this information since their customers will request the data from their suppliers. Furthermore, it is expected that the public opinion and consumer interests will force manufacturers to avoid the use of metals with questionable origin. Impact for existing products Several departments are involved in the process of collecting data and providing conflict minerals compliance information. For already marketed products, purchasing typically requests Conflict Minerals declarations from the suppliers. In order to address requests from customers, technical operations or product management are usually responsible for keeping track of all parts, raw materials and their suppliers so that the required information can be provided. For complex BOMs, it is very tedious to maintain complete, accurate, up-to-date, and traceable data. Any product change or new supplier can, in addition to all other implications, have an effect on the Conflict Minerals compliance status. Influence on product development  It makes sense to consider compliance early in the planning and design of new products. Companies should evaluate which metals are needed or contained in supplier parts and if these could originate from problematic sources. The answer influences the cost and risk analysis during the development. If it is known early on that a part could be non-compliant with respect to Conflict Minerals, alternatives can be evaluated and thus costly changes at a later stage can be avoided. Integrated compliance management  Ideally, compliance data for Conflict Minerals, but also for other regulations like REACH and RoHS, should be managed in an integrated supply chain system. The compliance status is directly visible across the entire BOM at any part level and for the finished product. If data is missing, a request to the supplier can be triggered right away without having to switch to another system. The entire process, from identification of the relevant parts, requesting information, handling responses, data entry, to compliance calculation is fully covered end-to-end while being transparent for all stakeholders. Agile PLM Product Governance and Compliance (PG&C) The PG&C module extends Agile PLM with exactly this integrated functionality. As with the entire Agile product suite, PG&C can be configured according to customer requirements: data fields, attributes, workflows, routing, notifications, and permissions, etc… can be quickly and easily tailored to a customer’s needs. Optionally, external databases can be interfaced to query commercially available sources of Conflict Minerals declarations which obviates the need for a separate supplier request in many cases. Suppliers can access the system directly for data entry through a special portal. The responses to the standard EICC-GeSI questionnaire can be imported by the supplier or internally. Manual data entry is also supported. A set of compliance-specific dashboards and reports complement the functionality Conclusion  The increasing number of product compliance regulations, for which Conflict Minerals is just one example, requires companies to implement an efficient data and process management in this area. Consumer awareness in this matter increases as well so that an integrated system from development to production also provides a competitive advantage.

  • Head in the Clouds

    - by Tony Davis
    We're just past the second anniversary of the launch of Windows Azure. A couple of years' experience with Azure in the industry has provided some obvious success stories, but has deflated some of the initial marketing hyperbole. As a general principle, Azure seems to work well in providing a Service-Oriented Architecture for services in enterprises that suffer wide fluctuations in demand. Instead of being obliged to provide hardware sufficient for the occasional peaks in demand, one can hire capacity only when it is needed, and the cost of hosting an application is no longer a capital cost. It enables companies to avoid having to scale out hardware for peak periods only to see it underused for the rest of the time. A customer-facing application such as a concert ticketing system, which suffers high demand in short, predictable bursts of activity, is a great example of an application that would work well in Azure. However, moving existing applications to Azure isn't something to be done on impulse. Unless your application is .NET-based, and consists of 'stateless' components that communicate via queues, you are probably in for a lot of redevelopment work. It makes most sense for IT departments who are already deep in this .NET mindset, and who also want 'grown-up' methods of staging, testing, and deployment. Azure fits well with this culture and offers, as a bonus, good Visual Studio integration. The most-commonly stated barrier to porting these applications to Azure is the problem of reconciling the use of the cloud with legislation for data privacy and security. Putting databases in the cloud is a sticky issue for many and impossible for some due to compliance and security issues, the need for direct control over data, and so on. In the face of feedback from the early adopters of Azure, Microsoft has broadened the architectural choices to cater for a wide range of requirements. As well as SQL Azure Database (SAD) and Azure storage, the unstructured 'BLOB and Entity-Attribute-Value' NoSQL storage alternative (which equates more closely with folders and files than a database), Windows Azure offers a wide range of storage options including use of services such as oData: developers who are programming for Windows Azure can simply choose the one most appropriate for their needs. Secondly, and crucially, the Windows Azure architecture allows you the freedom to produce hybrid applications, where only those parts that need cloud-based hosting are deployed to Azure, whereas those parts that must unavoidably be hosted in a corporate datacenter can stay there. By using a hybrid architecture, it will seldom, if ever, be necessary to move an entire application to the cloud, along with personal and financial data. For example that we could port to Azure only put those parts of our ticketing application that capture and process tickets orders. Once an order is captured, the financial side can be processed in our own data center. In short, Windows Azure seems to be a very effective way of providing services that are subject to wide but predictable fluctuations in demand. Have you come to the same conclusions, or do you think I've got it wrong? If you've had experience with Azure, would you recommend it? It would be great to hear from you. Cheers, Tony.

  • Why is x=x++ undefined?

    - by ugoren
    It's undefined because the it modifies x twice between sequence points. The standard says it's undefined, therefore it's undefined. That much I know. But why? My understanding is that forbidding this allows compilers to optimize better. This could have made sense when C was invented, but now seems like a weak argument. If we were to reinvent C today, would we do it this way, or can it be done better? Or maybe there's a deeper problem, that makes it hard to define consistent rules for such expressions, so it's best to forbid them? So suppose we were to reinvent C today. I'd like to suggest simple rules for expressions such as x=x++, which seem to me to work better than the existing rules. I'd like to get your opinion on the suggested rules compared to the existing ones, or other suggestions. Suggested Rules: Between sequence points, order of evaluation is unspecified. Side effects take place immediately. There's no undefined behavior involved. Expressions evaluate to this value or that, but surely won't format your hard disk (strangely, I've never seen an implementation where x=x++ formats the hard disk). Example Expressions x=x++ - Well defined, doesn't change x. First, x is incremented (immediately when x++ is evaluated), then it's old value is stored in x. x++ + ++x - Increments x twice, evaluates to 2*x+2. Though either side may be evaluated first, the result is either x + (x+2) (left side first) or (x+1) + (x+1) (right side first). x = x + (x=3) - Unspecified, x set to either x+3 or 6. If the right side is evaluated first, it's x+3. It's also possible that x=3 is evaluated first, so it's 3+3. In either case, the x=3 assignment happens immediately when x=3 is evaluated, so the value stored is overwritten by the other assignment. x+=(x=3) - Well defined, sets x to 6. You could argue that this is just shorthand for the expression above. But I'd say that += must be executed after x=3, and not in two parts (read x, evaluate x=3, add and store new value). What's the Advantage? Some comments raised this good point. It's not that I'm after the pleasure of using x=x++ in my code. It's a strange and misleading expression. What I want is to be able to understand complicated expressions. Normally, a complicated expression is no more than the sum of its parts. If you understand the parts and the operators combining them, you can understand the whole. C's current behavior seems to deviate from this principle. One assignment plus another assignment suddenly doesn't make two assignments. Today, when I look at x=x++, I can't say what it does. With my suggested rules, I can, by simply examining its components and their relations.

  • Shared Server Dreamhost

    - by Jseb
    I am trying to install an app on a shared server. If i understand properly because i am using a shared server, and that Dreamhost doesn't suppose rails 3.2.8 I must use FCGI, although i am not sure how to install and to make it run properly. From this tutorial http://wiki.dreamhost.com/Rails_3. To my understand here what I did, In dreamhost, activate PHP 5.x.x FastCGI and made sure Phusion Passenger is unchecked Create an app on my localmachine Because rails doesn't create a dispatch and access file i create the two following file in my /public folder dispatch.fcgi #!/home/username/.rvm/rubies/ruby-1.9.3-p327/bin/ruby ENV['RAILS_ENV'] ||= 'production' ENV['HOME'] ||= `echo ~`.strip ENV['GEM_HOME'] = File.expand_path('~/.rvm/gems/ruby 1.9.3-p327') ENV['GEM_PATH'] = File.expand_path('~/.rvm/gems/ruby 1.9.3-p327') + ":" + File.expand_path('~/.rvm/gems/ruby 1.9.3-p327@global') require 'fcgi' require File.join(File.dirname(__FILE__), '../config/environment') class Rack::PathInfoRewriter def initialize(app) @app = app end def call(env) env.delete('SCRIPT_NAME') parts = env['REQUEST_URI'].split('?') env['PATH_INFO'] = parts[0] env['QUERY_STRING'] = parts[1].to_s @app.call(env) end end Then created the file .htaccess <IfModule mod_fastcgi.c> AddHandler fastcgi-script .fcgi </IfModule> <IfModule mod_fcgid.c> AddHandler fcgid-script .fcgi </IfModule> Options +FollowSymLinks +ExecCGI RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ dispatch.fcgi/$1 [QSA,L] ErrorDocument 500 "Rails application failed to start properly" Uploaded to a folder and pointed to the public folder in dreamhost Made sure dispatch.fcgi has 777 for write ssh and run the following command in the public folder : ./dispatch.fcgi Crossing my finger but it doesn't work I get the following errors ./dispatch.fcgi: line 1: ENV[RAILS_ENV]: command not found ./dispatch.fcgi: line 1: =: command not found ./dispatch.fcgi: line 2: ENV[HOME]: command not found ./dispatch.fcgi: line 2: =: command not found ./dispatch.fcgi: line 3: syntax error near unexpected token (' ./dispatch.fcgi: line 3:ENV['GEM_HOME'] = File.expand_path('~/.rvm/gems/ruby 1.9.3-p327')' Doing wrong???

  • IDN aware tools to encode/decode human readable IRI to/from valid URI

    - by Denis Otkidach
    Let's assume a user enter address of some resource and we need to translate it to: <a href="valid URI here">human readable form</a> HTML4 specification refers to RFC 3986 which allows only ASCII alphanumeric characters and dash in host part and all non-ASCII character in other parts should be percent-encoded. That's what I want to put in href attribute to make link working properly in all browsers. IDN should be encoded with Punycode. HTML5 draft refers to RFC 3987 which also allows percent-encoded unicode characters in host part and a large subset of unicode in both host and other parts without encoding them. User may enter address in any of these forms. To provide human readable form of it I need to decode all printable characters. Note that some parts of address might not correspond to valid UTF-8 sequences, usually when target site uses some other character encoding. An example of what I'd like to get: <a href="http://xn--80aswg.xn--p1ai/%D0%BF%D1%83%D1%82%D1%8C?%D0%B7%D0%B0%D0%BF%D1%80%D0%BE%D1%81"> http://????.??/???????????</a> Are there any tools to solve these tasks? I'm especially interested in libraries for Python and JavaScript.
