  • Select a data template by item type programatically in WPF

    - by Michael Stoll
    Hi all, unfortunately the WPF ToolbarTray does not support binding to a collection of ToolbarViewModels (Correct me, if I'm wrong). Thus I want to create the Toolbars programmatically. So there are two tasks, which I don't know how to do: Select the data template based on the item type. Instantiate the data template as toolbar Both should do the same as WPF does, when we use ItemsControl with an enumerable content and empty template. I used reflector to anaylse what WPF does. Task 1 is done by FrameworkElement.FindTemplateResourceInternal, but this is internal, and I couldn't find any public methods to acomplish the task. Of course one could enumerate all resources and match the data template data type property, but this seems sub-optimal. Who know's how to acomplish these tasks?

  • Comprehensive HTML page for testing CSS?

    - by yaya3
    Looking for example code that uses semantic HTML that I can use to test stylesheets with. The version/doctype is unimportant though HTML5 would be great. When I say "comprehensive" - I am looking for use of definition lists, forms, tables, plus all the usual. Thanks

  • How to change a variable type in C#?

    - by Mosho Mulan
    I wanted to use something like this: if(x==5) { var mydb= ........ ; } else { var mydb = ........ ; } but it didn't work because I can't declare a variable inside if statement. So I tried to do this: var mydb; if (x==5) { mydb= ............. ; } else { mydb=.............; } but id didn't work either because I had to initialize the variable (mydb). So the question is: I don't necessarily know the type of the variable, can I declare it anyway and then change the type inside the if statement?

  • Measuring debug vs release of ASP.NET applications

    - by Alex Angas
    A question at work came up about building ASP.NET applications in release vs debug mode. When researching further (particularly on SO), general advice is that setting <compilation debug="true"> in web.config has a much bigger impact. Has anyone done any testing to get some actual numbers about this? Here's the sort of information I'm looking for (which may give away my experience with testing such things): Execution time | Debug build | Release build -------------------+---------------+--------------- Debug web.config | average 1 | average 2 Retail web.config | average 3 | average 4 Max memory usage | Debug build | Release build -------------------+---------------+--------------- Debug web.config | average 1 | average 2 Retail web.config | average 3 | average 4 Output file size | Debug build | Release build -------------------+---------------+--------------- | size 1 | size 2

  • Testing for security vulnerabilities on web applications

    - by Moak
    A lot of companies use CMS software that updates on the regular, often they are security fixes, implying that the previous version have security vulnerabilities. But most clients never upgrade this, or even the CMS has been modified so that an update would break the site. Are there sites that document these exploits, and instruct how to test for them? Or does this information not even get published? (in order not to have people try to exploit them) Also is there a generic php/js based check list to prevent hack attempts? I know about SQL injections and XSS, but I'm sure that there are more threats out there. Peace

  • Testing custom constraints in Grails App

    - by WaZ
    Hi there, I have the following as my unit test: void testCreateDealer() { mockForConstraintsTests(Dealer) def _dealer= new Dealer( dealerName:"ABC", Email:"[email protected]", HeadOffice:"", isBranch:false) assertFalse _dealer.validate() } But when I run the test I get the following error: No signature of method: static com.myCompany.Dealer.findByDealerNameIlike() is applicable for argument types: (java.lang.String) values: [ABC] I use some custom constraints in my domain class. How Can I test this? static constraints = { dealerName(blank:false, validator: { val, obj -> def similarDealer = Dealer.findByDealerNameIlike(val) return !similarDealer || (obj.id == similarDealer.id) } )

  • testing the controller in asp.net mvc

    - by csetzkorn
    Hi, I would like to test the validation of submitted DTO. This is the bare bone of a controller create action: [AcceptVerbs(HttpVerbs.Post)] public RedirectToRouteResult Create(SomeDTO SomeDTO) { SomeObject SomeObject = null; try { SomeObject = this.RepositoryService.getSomeObjectRepository().Create(SomeDTO, this.RepositoryService); } catch (BrokenRulesException ex) { ex.AddModelStateErrors(ModelState, "Model"); } catch (Exception e) { ModelState.AddModelError("Exception", e.Message); } TempData["ViewData"] = ViewData; TempData["SomeDTO "] = SomeDTO; return ModelState.IsValid ? RedirectToAction("SomeObjectDetail", new { Id = SomeObject.Id }) : RedirectToAction("Form"); } The mechanics , although not relevant, is as follows: I have a strongly typed view = form which submits a dto to this action which either returns the form or the details page of the created object. I would like to unit test whether the Model contains certain key/errorMessage combinations given some invalid dto. Did someone do similar stuff? Any pointers would be very much appreciated. Thanks. Best wishes, Christian

  • bool as object vs string as object testing equality

    - by Ray Pendergraph
    I am relatively new to C# and I noticed something interesting today that I guess I have never noticed or perhaps I am missing something. Here is an NUnit test to give an example: object boolean1 = false; object booloan2 = false; Assert.That(boolean1 == booloan2); This unit test fails, but this one passes: object string1 = "string"; object string2 = "string"; Assert.That(string1 == string2); I'm not that surprised in and of itself that the first one fails seeing as boolean1 and boolean2 are different references. But it is troubling to me that the first one fails and the second one passes. I read (on MSDN somewhere) that some magic was done to the String class to facilitate this. I think my question really is why wasn't this behavior replicated in bool? As a note... if the boolean1 and 2 are declared as "bool" then there is no problem. Does anyone know the reason for these differences or why it was implemented that way? Can anyone think of a situation where you would want to reference a bool object for anything except its value?

  • Core Data data type for just the date - not including time

    - by Jason
    I am new at Core Data, and it seems like it is a great way to manage the data store. However I am also very memory-conscious due to the fact that the iPhone doesn't have that much of it. I was a little surprised to see that the data types are so limited - eg. there is a Date type which includes also the time, but no Date type for just the date! All the time information takes up precious bytes of memory, if I just wanted an attribute with the date (e.g. 2/15/2010 rather than 2/15/2010 02:34:48), how could I do this? Is it possible?

  • saving a records containing a member of type string to a file (Delphi, Windows)

    - by wonderer
    I have a record that looks similar to: type TNote = record Title : string; Note : string; Index : integer; end; Simple. The reason I chose to set the variables as string (as opposed to an array of chars) is that I have no idea how long those strings are going to be. They can be 1 char long, 200 or 2000. Of course when I try to save the record to a type file (file of...) the compiler complains that I have to give a size to string. Is there a way to overcome this? or a way to save those records to an untyped file and still maintain a sort of searchable way? Please do not point me to possible solutions, if you know the solution please post code. Thank you

  • Testing code that uses SoftReference<T>

    - by bmargulies
    To get any code with SoftReference<T> to be fully tested, one must come up with some way to test the 'yup, it's been nulled' case. One might more or less mock this by using a 'for-test' code path to force the reference to be null, but that won't manage the queue exactly as the GC does. I wonder if anyone out can share experience in setting up a repeatable, controlled, environment, in which the GC is, in fact, provoked into collecting and nulling?

  • Visual Studio - easy way to bring up type definition as source code

    - by Igor Zevaka
    Oftentimes I want to bring up a system class in a source view, so that I can browse the properties and methods exposed by the class in a source view. Below is the screenshot of what I mean: Usually I do this by selecting the class name and pressing F12 (or right clickGo To Definition). However, if I haven't got it anywhere ready, i have type it up and then do Go To Definition. Most of the time I have to delete what I typed later on. Is there a way to bring up this view without having to type the class name? The VS2010 Navigate To dialog doesn't support this.

  • How to test reliability of my own (small) embedded operating system ?

    - by TridenT
    I've written a small operating system for embedded project running on small to medium target. I added some automated unit test with a high test code coverage (95%), but the scope is only the static part. I got some code metrics as complexity and readability. I'm testing my code with a rule checker with MiSRA support, and of course fixed all warnings. I'm testing the code with a static analyzer and again fixed all warnings. What can I do now to test - and improve - the reliability of my OS ? How about the dynamic part ?

  • Ruby on Rails: restrict file type with Paperclip using a flash uploader

    - by aperture
    I have a pretty basic Paperclip Upload model that is attached to a User model through has_many, and am using Uploadify to do the actual uploading. Flash sends all files with the content type of "application/octet-stream" so using validates_attachment_content_type rejects all files. In my create action, I am able to get the mime-type from the original file name, but only after it's been saved, with: def coerce(params) h = Hash.new h[:upload] = Hash.new h[:upload][:attachment].content_type = MIME::Types.type_for(h[:upload][:attachment].original_filename).to_s ... end and def create diff_params = coerce(params) @upload = Upload.new(diff_params[:upload]) ... end What would be the best way of white listing file types? I am thinking a before_validation method, but I'm not sure how that would work. Any ideas would be welcome.

  • Using Selenium-IDE with a rich Javascript application?

    - by Darien
    Problem At my workplace, we're trying to find the best way to create automated-tests for an almost wholly javascript-driven intranet application. Right now we're stuck trying to find a good tradeoff between: Application code in reusable and nest-able GUI components. Tests which are easily created by the testing team Tests which can be recorded once and then automated Tests which do not break after small cosmetic changes to the site XPath expressions (or other possible expressions, like jQuery selectors) naively generated from Selenium-IDE are often non-repeatable and very fragile. Conversely, having the JS code generate special unique ID values for every important DOM-element on the page... well, that is its own headache, complicated by re-usable GUI components and IDs needing to be consistent when the test is re-run. What successes have other people had with this kind of thing? How do you do automated application-level testing of a rich JS interface? Limitations We are using JavascriptMVC 2.0, hopefully 3.0 soon so that we can upgrade to jQuery 1.4.x. The test-making folks are mostly trained to use Selenium IDE to directly record things. The test leads would prefer a page-unique HTML ID on each clickable element on the page... Training the testers to write or alter special expressions (such as telling them which HTML class-names are important branching points) is a no-go. We try to make re-usable javascript components, but this means very few GUI components can treat themselves (or what they contain) as unique. Some of our components already use HTML ID values in their operation. I'd like to avoid doing this anyway, but it complicates the idea of ID-based testing. It may be possible to add custom facilities (like a locator-builder or new locator method) to the Selenium-IDE installation testers use. Almost everything that goes on occurs within a single "page load" from a conventional browser perspective, even when items are saved Current thoughts I'm considering a system where a custom locator-builder (javascript code) for Selenium-IDE will talk with our application code as the tester is recording. In this way, our application becomes partially responsible for generating a mostly-flexible expression (XPath or jQuery) for any given DOM element. While this can avoid requiring more training for testers, I worry it may be over-thinking things.

  • Adding and Testing Compatibility of External Jar to Blackberry Project

    - by pujakhemka
    Hi, I am a newbie at Blackberry development. I have Eclipse 3.5.1 and Blackberry JRE 4.7.0. In my application, I added 2 external jars to my project and a properties file. I do not know for sure whether the jars I am trying to add and the webservices I am calling are compatible with Blackberry. I have to test that too. When I tried running my project, I get - "Project has verification Error". Is it because I did not add the external jars correctly? Or is it because the jars may not be compatible with Blackberry?

  • Testing file uploading and downloading speed using FTP

    - by Toman
    Hi all, I am working in a desktop application using java. In my application i have to perform a speed test which will show the file uploading and downloading speed. For uploading test i am uploading a small test file to a FTP server and based on time taken i am calculating the file upload speed. similarly i am downloading a test file form server and calculating download speed. But result i am getting doesn't match with actual FTP file uploading and downloading speed.it seems that the establishing connection to FTP server is increasing the time, hence the resultant speed i am calculating is less. Could you suggest any link or some way to get nearest uploading and downloading speed. i thanks to all your valuable suggestion.

  • Constructor type not found

    - by WaffleTop
    Hello, What I am doing: I am taking the Microsoft Enterprise Library 4.1 and attempting to expand upon it using a few derived classes. I have created a MyLogEntry, MyFormatter, and MyTraceListener which derive from their respective base classes when you remove the "My" from their names. What my problem is: Everything compiles fine. When I go to run a test using Logger.Write(logEntry) it errors right after it initializes MyTraceListener with an error message: "The current build operation (... EnterpriseLibrary.Logging.LogWriter, null]) failed: Constructor on type 'MyLogging.MyFormatter' not found. (Strategy type ConfiguredObjectStrategy, index 2) I figured it was something to do with the constructor so I tried removing it, add it, and adding a call to the base class LogFormatter. Nothing has worked. Does anyone have insight into this problem? Is it maybe a reference issue? Bad App.config configuration? Thank you in advance
