  • Why are types found on an imported namepace but not on a fully qualified namespace after retargeting the framework?

    - by Paul Ferguson
    We've just re-targeted a VB.NET project from .Net 2.0 to 3.5. Various framework types are now missing from our project. Wherever the type is referenced using a fully qualified namespace it's missing. If the relevant namespace is imported for the type; it's found. For example, this doesn't find the type Object, with compiler error "System.Object is not defined.": Public Class Foo Inherits System.Object End Class However, this works ok: Imports System Public Class Foo Inherits [Object] End Class I've already tried re-opening the solution with no success.

  • ASP.net MVC Linq-To-SQL Many-To-Many Field Binding

    - by user336858
    Hi there, The short version of this question is "Is there a way to gracefully handle database insertion for an object that has a many-to-many field that has been set up in a partial class?" Apologies if it's been asked before. Example Suppose I have a typical MVC setup with the tables: Posts {PostID, ...} Categories {CategoryID, ...} A post can have more than one category, and a category can identify more than one post. Thus suppose further that I need an extra table: PostCategories {PostID, CategoryID, ...} This handles the many-to-many relationship between posts and categories. As far as I know, there's no way to do this in Linq-to-SQL right now so I have to shoehorn it in by adding a partial Post class to the project to add that functionality. Something like: public partial class Post { public IEnumerable<Category> Categories{ get { ... } set { ... } } } So I can now create a "Create" view that automatically populates a "Categories" UI item. This is where the trouble starts. So here's my question: How do you get automatic object model binding to work cleanly with an object that has a many-to-many relationship to control? The workaround that makes many-to-many relationships possible relies on the Post object having a PostID in order to be associated with CategoryID(s), which is only issued after the Post object has been submitted for validation and insertion. Bit of a Catch22 here. Any terminology, links, or tips you can provide would be tremendously helpful!

  • Visual Studio Unit Test failure to start

    - by swmi
    Hi, I am having an issue when starting the tests under debug mode in Visual Studio 2008 Team Test where it gives the following error: "Failed to queue test run '{user@machinename}': Object reference not set to an instance of an object." I googled for the error but no joy. Don't even understand what it means as it is too brief. Has anyone come across this? Note that I can run tests fine if I am not debugging and I get the same error irrespective of the test I run. Thank you, Swati ETA: Being new to Visual Studio Team Test, I didn't know there was a better exception log then what I was seeing. Anyhow, here it is: <Exception> System.NullReferenceException: Object reference not set to an instance of an object. at Microsoft.VisualStudio.TestTools.TestCaseManagement.QualityToolsPackage.

  • Why is a NullReferenceException thrown when a ToolStrip button is clicked twice with code in the `Click` event handler?

    - by Patrick
    I created a clean WindowsFormsApplication solution, added a ToolStrip to the main form, and placed one button on it. I've added also an OpenFileDialog, so that the Click event of the ToolStripButton looks like the following: private void toolStripButton1_Click(object sender, EventArgs e) { openFileDialog1.ShowDialog(); } I didn't change any other properties or events. The funny thing is that when I double-click the ToolStripButton (the second click must be quite fast, before the dialog opens), then cancel both dialogs (or choose a file, it doesn't really matter) and then click in the client area of main form, a NullReferenceException crashes the application (error details attached at the end of the post). Please note that the Click event is implemented while DoubleClick is not. What's even more strange that when the OpenFileDialog is replaced by any user-implemented form, the ToolStripButton blocks from being clicked twice. I'm using VS2008 with .NET3.5. I didn't change many options in VS (only fontsize, workspace folder and line numbering). Does anyone know how to solve this? It is 100% replicable on my machine, is it on others too? One solution that I can think of is disabling the button before calling OpenFileDialog.ShowDialog() and then enabling the button back (but it's not nice). Any other ideas? And now the promised error details: System.NullReferenceException was unhandled Message="Object reference not set to an instance of an object."

  • How to loop a json array and update links

  • Show SVG files on Sharepoint 2007

    - by Nicolas Irisarri
    I'm building a WSS site which has to show SVG files stored on WSS. I'm trying to use <object> tag to show it and it doesn't show, however, if I use <embed> it works ok. Im'using IE8 and IE7 I've been reading and everyone tells IE prefers <Object> over <embed>, but in WSS it doesn't work this way. To display the file I'm using a web content editor webpart with this code: <object type="image/svg+xml" data="/samples/sample.svg" name="owMain" width="400" height="150"> </object> Any clue??

  • Design Patterns: What is a type

    - by contactmatt
    A very basic question, but after reading the "Design Patterns: Elements of reusable OO Software" book, I'm a little confused. The book states, "An object's type only refers to its interface-the set of request to which it can respond. An object can have many types, and objects of different classes can have the same type." Could someone please better explain what a Type is? I also don't understand how one object can have multiple types...unless the book is speaking of polymorphism....

  • No method 'get' on backbone model save

    - by user888734
    I'm using backbone for a reasonably complicated form. I have a number of nested models, and have been computing other variables in the parent model like so: // INSIDE PARENT MODEL computedValue: function () { var value = this.get('childModel').get('childModelProperty'); return value; } This seems to work fine for keeping my UI in sync, but as soon as I call .save() on the parent model, I get: Uncaught TypeError: Object #<Object> has no method 'get' It seems that the child model kind of temporarily stops responding. Am I doing something inherently wrong? EDIT: The stack trace is: Uncaught TypeError: Object #<Object> has no method 'get' publish.js:90 Backbone.Model.extend.neutralDivisionComputer publish.js:90 Backbone.Model.extend.setNeutralComputed publish.js:39 Backbone.Events.trigger backbone.js:163 _.extend.change backbone.js:473 _.extend.set backbone.js:314 _.extend.save.options.success backbone.js:385 f.Callbacks.o jquery.min.js:2 f.Callbacks.p.fireWith jquery.min.js:2 w jquery.min.js:4 f.support.ajax.f.ajaxTransport.send.d

  • Website visitors are still being redirected after "fixing" the damage from a conditional redirect website attack

    - by Shannon
    BACKGROUND A website of mine was recently the target of a conditional redirect attack. PHP code was added to my pages to redirect visitors. The .htaccess file was edited to redirect visitors. I've re-uploaded my website so the compromised PHP and .htaccess code have both been removed. My site is mostly handwritten php and static HTML content. I don't use page comments or any third party libraries. THE PROBLEM After removing the compromised php and htaccess files, visitors are still being re-directed. What could be the reason that visitors are still being redirected? Are there any tools to check where/how redirects are taking place so I can debug the problem? UPDATE - PROBLEM FIXED As suggested in the comments, I cleared my Firefox cache and that fixed the problem (for me anyway). Visitors with old cache data will obviously still be re-directed.

  • PHP Flatten Array with multiple leaf nodes

    - by tafaju
    What is the best way to flatten an array with multiple leaf nodes so that each full path to leaf is a distinct return? array("Object"=>array("Properties"=>array(1, 2))); to yield Object.Properties.1 Object.Properties.2 I'm able to flatten to Object.Properties.1 but 2 does not get processed with recursive function: function flattenArray($prefix, $array) { $result = array(); foreach ($array as $key => $value) { if (is_array($value)) $result = array_merge($result, flattenArray($prefix . $key . '.', $value)); else $result[$prefix . $key] = $value; } return $result; } I presume top down will not work when anticipating multiple leaf nodes, so either need some type of bottom up processing or a way to copy array for each leaf and process (althought that seems completely inefficient)

  • Is there a Firebug console -vsdoc.js?

    - by David Murdoch
    If not, does anyone care to write one? I would do it myself...but I don't have time right now...maybe next week (unless someone beats me to it). If you are bored and want to compile the vsdoc: Here is the Firebug API. Here is a blog post about the format for VS doc comments for intellisense. Here is an example vsdoc (jquery-1.4.1-vsdoc.js). I created the following because I kept typing cosnole instead of console. You can use it as a starting point (ish). console = { /// <summary> /// 1: The javascript console /// </summary> /// <returns type="Object" /> }; console.log = function (object) { /// <summary> /// Write to the console's log /// </summary> /// <returns type="null" /> /// <param name="object" type="Object"> /// Write the object to the console's log /// </param> };

  • Generic JSON parser in .NET / WPF?

    - by niklassaers
    I've read lots of tutorials on how to deserialize a JSON object to an object of a particular using DataContractJsonSerializer. However, I'd like to deserialize my object to a Dictionary consisting of either Strings, Arrays or Dictionaries, such as System.Json does with SilverLight when I say JsonObject.Parse(myJSONstring). Is there an equivalent to System.Json that I can use in my WPF project? (just a short background: I'm fetching JSON objects that have way to much info, and I just want to use a little bit to fill out a String array) Cheers Nik

    In IIS 5 files in the url: http://acme.com/_cache/cache-www.acme.com/v3.css are not accessible. All files below "cache-www.acme.com" are unreachable. I've verified that the files exists. Permissions are not a problem. I've assigned "Everyone" to the files and give "Everyone" full rights. What I have determined is in IIS 5 if there is a domain in the folder path, IIS 5 gets confused... Other javascript files outside the directory comedown fine... Any thoughts?

  • Design: How to declare a specialized memory handler class

    - by Michael Dorgan
    On an embedded type system, I have created a Small Object Allocator that piggy backs on top of a standard memory allocation system. This allocator is a Boost::simple_segregated_storage< class and it does exactly what I need - O(1) alloc/dealloc time on small objects at the cost of a touch of internal fragmentation. My question is how best to declare it. Right now, it's scope static declared in our mem code module, which is probably fine, but it feels a bit exposed there and is also now linked to that module forever. Normally, I declare it as a monostate or a singleton, but this uses the dynamic memory allocator (where this is located.) Furthermore, our dynamic memory allocator is being initialized and used before static object initialization occurs on our system (as again, the memory manager is pretty much the most fundamental component of an engine.) To get around this catch 22, I added an extra 'if the small memory allocator exists' to see if the small object allocator exists yet. That if that now must be run on every small object allocation. In the scheme of things, this is nearly negligable, but it still bothers me. So the question is, is there a better way to declare this portion of the memory manager that helps decouple it from the memory module and perhaps not costing that extra isinitialized() if statement? If this method uses dynamic memory, please explain how to get around lack of initialization of the small object portion of the manager.

  • How to render consistence and smooth moving animation on iphone / ipod / iphone simulator.

    - by shakthi
    I am trying render a simple animation(object movement animations) on iphone. I used opengl for object rendering. Movements appears to be smooth on the simulator. But if I used same code in the ipod, object movement is slower. In the iphone it is still slower. I googled a bit and found 'frame rate independent rendering method', which taught me the concept of 'time interval' and object movement based on it. However result is very unpleasant. There is a lot of jerk in the animation even when fps remains above 20. Following code fragment is used for calculation of time interval between successive frames and I am using that to move my animation. NSTimeInterval GetTimeIntervals(NSTimeInterval * inLastElapsedTime ) { NSTimeInterval intervalTime = 0; NSTimeInterval currentTime = [NSDate timeIntervalSinceReferenceDate]; if(*inLastElapsedTime != 0 ) { intervalTime = currentTime - *inLastElapsedTime; } *inLastElapsedTime = currentTime; return intervalTime; }

    I'm going to purchase Intel® Core™2 Duo Processor E7500 (3M Cache, 2.93 GHz, 1066 MHz FSB) and for motherboard my local vendor suggesting me to purchase Intel DG41RQ MB motherboard and he is also saying if i'm purchasing Intel CPU then purchasing Intel's Own motherboard with intel chipset will give best performance. Is it true? To get good inbuilt graphic I'm thinking to purchase nvidia chipset based motherboard of any other company like Asus, Gigabyte, MSi etc. is it ok? Although i never play games on my PC but thinking Inbuilt Nvidia graphics will be better for running Photoshop and watching movies then Intel's inbuilt graphics. or it's ok to purchase Intel DG41RQ MB motherborad as suggested by local vendor. Intel's inbuilt graphics would be enough for Photoshop and Watching movies. If you know any other good motherboard for Intel® Core™2 Duo Processor E7500 (3M Cache, 2.93 GHz, 1066 MHz FSB) then tell.

  • Skip HTML escape in custom label_tag helper in Rail 3

    - by tricote
    Hi, I have this nice class ErrorFormBuilder that allows me to add the error description near the corresponding field in the form view : class ErrorFormBuilder < ActionView::Helpers::FormBuilder #Adds error message directly inline to a form label #Accepts all the options normall passed to form.label as well as: # :hide_errors - true if you don't want errors displayed on this label # :additional_text - Will add additional text after the error message or after the label if no errors def label(method, text = nil, options = {}) #Check to see if text for this label has been supplied and humanize the field name if not. text = text || method.to_s.humanize #Get a reference to the model object object = @template.instance_variable_get("@#{@object_name}") #Make sure we have an object and we're not told to hide errors for this label unless object.nil? || options[:hide_errors] #Check if there are any errors for this field in the model errors = object.errors.on(method.to_sym) if errors #Generate the label using the text as well as the error message wrapped in a span with error class text += " <br/><span class=\"error\">#{errors.is_a?(Array) ? errors.first : errors}</span>" end end #Add any additional text that might be needed on the label text += " #{options[:additional_text]}" if options[:additional_text] #Finally hand off to super to deal with the display of the label super(method, text, options) end end But the HTML : text += " <br/><span class=\"error\">#{errors.is_a?(Array) ? errors.first : errors}</span>" is escaped by default in the view... I tried to add the {:escape = false} option : super(method, text, options.merge({:escape => false})) without success Is there any way to bypass this behavior ? Thanks

  • Is Dynamic Casting Possible in Java

    - by Tom Tucker
    So I have a class of overloaded methods like this: class Foo { public void test(Object value) { ... } public void test(String value) { ... } } I need to pass a property value of a bean to one of these methods depending on its type, but I don't know the actual property type until the runtime. e.g. public void run(Object bean, String propertyName) { Foo foo = new Foo(); foo.test(PropertyUtils.getProperty(bean, propertyName)); } BTW, PropertyUtils.getProperty() is a helper method that returns a value of the specified property on a bean. PropertyUtils.getProperty() returns an Object, so that test(Object value) will be always called and the actual property type will be ignored. I can figure out the propery type in the runtime, even if its value is null. Is there such a thing as dynamic casting in Java? If not, is there a way to have an overloaded method with the correct parameter type called?
