  • Second Unit Test Not Running

    - by TomJ
    I am having trouble getting my Method B test to run. The logic is fine, but when the unit tests are run, only Method A will run. If Method A and B are switched in terms of spots, only Method B will run. So clearly the code is wrong at some point. Do I need to call method B's test from inside method A in order to get both unit tests to run? I'm pretty new to C#, so forgive my basic question. using redacted; using Microsoft.VisualStudio.TestTools.UnitTesting; using System; namespace UnitTests { [TestClass()] public class ClassTest { public TestContext TestContext{get;set;} [TestMethod()] public void MethodATest() { the unit test } [TestMethod()] public void MethodBTest() { the unit test } } }

  • Deserialising Json to derived types in Asp.Net Web API

    - by IoChaos
    I'm calling a method of my WebAPI sending a json that I would like to match (or bind) with a model. In the controller I have a method like: public Result Post([ModelBinder(typeof(CustomModelBinder))]MyClass model); 'MyClass', wich is given as a parameter is an abstract class. I would like that at, depending of the type of json passed, the correct inherited class is instantiated. To achieve it, I'm trying to implement a custom binder. The problem is that (I don't know if it's very basic but I can't find anything) I don't know how to retrieve the raw Json (or better, some kind of serialization) that comes in the request. I see: actionContext.Request.Content But all methods are exposed as async. I don't know who this fits with passing the generate model to the controller method... Thanks a lot!

  • Simple Obj-C Memory Management Question

    - by yar
    This is from some sample code from a book // On launch, create a basic window - (void)applicationDidFinishLaunching:(UIApplication *)application { UIWindow *window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:[[HelloController alloc] init]]; [window addSubview:nav.view]; [window makeKeyAndVisible]; } But a release is never called for window nor for nav. Release should be called since alloc was called, right? If #1 is right, then I would need to store a reference to each of these in an instance variable in order to release them in the dealloc? Perhaps I'm wrong all around...

  • ASP.NET/VB/SQL: trying to insert data, getting error "no value given for required parameters"

    - by Sara
    I am pretty sure this is a basic syntax error, I am new at this and basically figuring things out by trial and error... I am trying to insert data from textboxes into an Access database, where the primary key fields in tableCourse are prefix and course_number. It keeps giving me the "no value given for one or more required parameters" error. Here is my codebehind: Protected Sub Wizard1_FinishButtonClick(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.WizardNavigationEventArgs) Handles Wizard1.FinishButtonClick 'Collect Data Dim myDept = txtDept.Text Dim myFirst = txtFirstName.Text Dim myLast = txtLastName.Text Dim myPrefix = txtCoursePrefix.Text Dim myNum = txtCourseNum.Text 'Define Connection Dim myConn As New OleDbConnection myConn.ConnectionString = AccessDataSource1.ConnectionString 'Create commands Dim myIns1 As New OleDbCommand("INSERT INTO tableCourse (department, name_first, name_last, prefix, course_number) VALUES (@myDept, @myFirst, @myLast, @myPrefix, @myNum)", myConn) 'Execute the commands myConn.Open() myIns1.ExecuteNonQuery() End Sub

  • How to analyse Wikipedia article's data base with R?

    - by Tal Galili
    Hi all, This is a "big" question, that I don't know how to start, so I hope some of you can give me a direction. And if this is not a "good" question, I will close the thread with an apology. I wish to go through the database of Wikipedia (let's say the English one), and do statistics. For example, I am interested in how many active editors (which should be defined) Wikipedia had at each point of time (let's say in the last 2 years). I don't know how to build such a database, how to access it, how to know which types of data it has and so on. So my questions are: What tools do I need for this (besides basic R) ? MySQL on my computer? RODBC database connection? How do you start planning for such a project?

  • Reduce the number of queries in EF

    - by Gio2k
    I have the following Model: Entities: Product (Contains basic data for products: price, etc) Attribute (Contains data for all possible optional attributes) ProductAttribute (Contains data for optional attributes of a product, eg. Color, Model, Size). ProductAttribute is essentially a many to many relationship with payload (ProductId, AttributeID, Value) And this piece of code: private static void ListAttributes(Product p) { p.ProductAttributes.Load(); foreach (var att in p.ProductAttributes) { att.Attribute.load(); Console.WriteLine("\tAttribute Name:{0} - Value {1}", att.Attribute.Name, att.AttributeValue); } } This piece of code will fire a query for each time the att.Attribute.Load() method is called in the foreach loop, only so i can get display the name of the attribute. I would like to fetch the Attribute.Name together with the query that fetches all attribute values, i.e. join ProductAttribute and Attribute. Is there any way to achieve this within my method?

  • How can a language be interpreted by itself (like Rubinius)?

    - by japancheese
    I've been programming in Ruby for a while now with just the standard MRI implementation of Ruby, but I've always been curious about the other implementations I hear so much about. I was reading about Rubinius the other day, a Ruby interpreter written in Ruby. I tried looking it up in various places, but I was having a hard time figuring out exactly how something like this works. I've never had much experience in compilers or language writing but I'm really interested to figure it out. How exactly can a language be interpreted by itself? Is there a basic step in compiling that I don't understand where this makes sense? Can someone explain this to me like I'm an idiot (because that wouldn't be too far off base anyways)

  • How should I structure my iPhone OpenGL ES 1.1 game?

    - by Ryan
    I am building an iPhone OpenGL ES 1.1 game. I am using the OpenGL ES template provided by xcode. I am only using the ES1Renderer. I've coded some basic touch actions the user can take, and I've begun to think about the overall structure of the code. All I'm really doing is using C in the ES1Renderer.m for my entire game state. I have an array of bullet structs, an array on enemy structs, etc.. Besides using this structure, where my entire game state is in ES1Renderer.m as C arrays and structs, what other ways are there to structure the code? Should I be using C++ or Objective-C classes to represent the enemies so they are more modular? The main reason I ask this is because I don't normally code in C, C++ and Objective-C..so I am a little fuzzy on coming up with a good architecture here.

  • Which language + framework should I use for building standalone clients for my PHP webapp?

    - by Jagira
    Hello, I have a PHP web application which basically maintains a set of user profiles and their records. My users are using the app via browser. I am planning to build a standalone desktop client/app for WINDOWS OS, in which a user can login, retrieve and modify the records. Which language + framework will be simple, fast and lightweight to use? I can think of the following options: Microsoft Visual Basic - simplest? Microsoft Visual C++ Python PHP + bambalam compiler Are there any other options? And which of these is better?

  • C++ - Print Out Objects From Set

    - by John Smith
    If I have a C++ set, declaration set personList; with iterator, set::const_iterator location; how can I print out the contents of the set? They are all person objects, and I have overridden the operator<< for Person. The line that errors is: cout << location and it's in a basic for loop. Netbeans gives the following error: proj.cpp:78: error: no match for ‘operator<<’ in ‘std::cout << location’ so it looks like it wants an override for the iterator's <<. Basically, I am taking objects that used to be stored in an array format, but are now in a set. What is the equivalent to cout << array[i] for sets?

  • How to convert "9:00 PM EST" to a Date object

    - by Bara
    I am developing an Android application and require some basic datetime manipulation. I have a Date object (from Java.util.Date) holding a specific date. I need to add a specific time to it. The time I have is a string in this format: "9:00 PM EST" How would I "add" this time to the previous date? If the Date object currently has: "4/24/10 00:00:00" How would I change it to instead be: "4/24/10 09:00:00 EST" I would prefer to do this without the use of an external library, if possible.

  • Produce a script to hit Google once a day and log our position in the results?

    - by hawbsl
    The need has arisen within our organisation to monitor (on a daily basis) where our site appears (both organic and PPC) on the page 1 of Google. Also where a key competitor appears. For certain key words. In the immediate short term a colleague is doing this by hitting Google manually and jotting down the results. Yep. It occurs to us we can write a script (e.g. using C#) to do this. I know Analytics will tell us an awful lot but it doesn't note the competitor's position, plus I don't think it has other data we want. Question is, is there an existing basic tool which does this (for free, I guess)? And if we write it ourselves, where to start and are there obvious pitfalls to avoid (for example can Google detect and block automated requests?)

  • Change CkEditor's background color with jQuery methods

    - by user198003
    I need to change background color of CkEditor, on some basic jQuery methods, like ready, change, etc. Tried with things like: $(document).on('click','.change-task-status', function(e){ $(".cke_editable").css("background-color", 'red'); }) ... but nothing happens. Can you help me how to achieve this? Thank you in advance! PS. yes, I do have jQuery adapter loaded on page. UPDATE: Some improvement is made - when I run next code in console, it changes background color $( ".cke_wysiwyg_frame" ).contents().find( ".cke_editable" ).css( "background-color", "#BADA55" ); Now just to find why it does not execute in code...

  • Syntax Highlighting in a ListBox

    - by ph0enix
    Hi all, I've searched the web and I can't seem to find anything that will work for me. I've seen plenty of discussion, and even some fairly extensible open-source tools, for code editors that provide line numbers and syntax highlighting. Here's my dilemma... I'm working on a "digital code review" project in C#.NET that allows users to specify source files, add them to a particular session, and other users can make comments and line references to the files being reviewed. Basic requirements: Must be written in C#.NET I don't need to be able to edit the text in the text box Users need to be able to select a line (or multiple lines), to make line references. It seems to me that I need some fancy implementation of a ListBox control (not a drop-down list) that has some OwnerDraw capabilities to add line numbers and syntax highlighting. Unfortunately, I haven't had any luck putting it together myself, and I can't seem to find a control that's already been written or a reference on how I might be able to accomplish this. Any suggestions??

  • How can I tell if an ADODB::_RecordsetPtr has already been created?

    - by scottm
    I am trying to write a class that uses ADO to retrieve SQL records. The intent is for the class to maintain one private recordset an other methods move forward, retrieve fields, etc. This is a basic example of my class: class SqlADO { private: ADODB::_RecordsetPtr m_recordset; public: void Open(); //open the connection void Execute(const char* sql); // creates or replaces current recordset void Next(); //moves recordset cursor forward void Field(const char* fieldName); //retrieves field name from current record of the recordset }; My Questions: In the Execute method, how can I check to see that the recordset instance has been created (or do I need to) so that I can close it first? Do you know of any good ADO COM Interop references?

  • Ranged integers in .NET (or C#)

    - by Mal Ross
    Am I being blind, or does the .NET framework not provide any kind of ranged integer class? That is, a type that would prevent you setting a value outside some given bounds that are not the full range of the basic data type. For example, an integer type that would restrict its values to between 1 and 100. Showing my age here, but back in '93, I remember using that sort of thing in Modula-2 (eeek!), but I've not seen explicit framework / language support for it since. Am I just missing something, or is it a case of "it's so simple to make your own that the framework doesn't bother"? Cheers.

  • user specific persistent cck types in drupal

    - by Fion
    Is there a way to do the following. We need to have a few basic cck types that will allow users to track their chosen parameters over a length of time. For example, one cck type may be called "numeric tracker" It would have a field for labeling the type and a field for entering a number. User A might label one numeric tracker "miles driven". Then each day user A would use this type to enter a number. User B might label a numeric tracker "hours slept". Each day user B would enter a number. Is there a way to use cck in this way?

  • Tutorials for an experienced C# user to learn C++

    - by Tim R.
    Are there any good resources for learning C++ that a C# user could use, which don't require knowledge of C? I have quite a good knowledge of C# via courses in my University's game development program (in a 300 level course right now) but now I need to use C++ for a project. I would use a beginner tutorial but they are so hard for me to follow and learn the basic syntax because they start so slowly. I found a few of tutorials for switching from C++ to C#, but none in the other direction. I do have a little bit of Objective C practice from iPhone programming as well.

  • Formula for Live Video Streaming Bitrate

    - by MD
    I am simply looking for the formula that should be used here. All the results I've found base "finding the bitrate" off of already existing video. I'm talking about LIVE streaming. (indeterminate length) So, I know some basic parts of it, but I just need to know if I'm right or missing anything. For Kbps: Resolution * Framerate / 1024 Is it really that simple? Audio would be a separate element for our purposes here. Am I missing anything from this formula? (Coming up with a proposal of what amount of bandwidth would be required, relative to possible resolution options, so I just need to be sure that I'm not missing anything or inaccurate about it)

  • Filemaker XSL 20sec Query Latency

    - by Ian Wetherbee
    I have an ASP frontend that loads data from a Filemaker database using XSL to perform simple queries. The problem is that the first page load takes 20 seconds +/- 200ms, then the next few page refreshes within a minute of the first request take <200ms, then the cycle starts over again. Each page load makes only 2 XSL queries, and they execute fast after the first page load, so what is causing the delay on the first page load? I have caching turned up with a 100% hit rate, and number of connections at 100. I've tried with XSL database sessions on and off, and session time anywhere from 1 to 60 minutes without any changes. The XSL loads from ASP use a GET request and add a Basic Authorization header to authenticate each time. During fast page requests, the fmserver.exe and fmswpc.exe processes don't even flinch, but during a 20 second holdup I see fmserver jump to 30% CPU and a 3mb I/O read a few seconds into the request, and occasionally fmswpc jump to 60% CPU.

  • Math Problem With Percentages

    - by TheDarkIn1978
    i'm terrible at math. trust me, you math experts will see why after reading my question. i have an object that is 300px in height. i need to calculate the percentage of that height where 90% = 300px (or the full height), 45% = 150px, 0% = 0px. so essentially, if i ask for 45% of the object's height, it will return 150px, or if i ask for 32% of the object's height, it will return __? i believe this is really basic math, so i apologize in advance.

  • Changing dalvik/libcore causes rebuilding the whole framework

    - by ZelluX
    I'm adding some interception routines to Dalvik libcore methods (e.g. file open method in libcore/luni/src/main/java/org/apache/harmony/luni/platform/OSFileSystem.java), which I think only changes basic sharing libraries. But to my surprise, every time I run make after modifications, it rebuilds nearly everything of the framework, such as Calculator application, W3C DOM parser, etc. It really takes time to build the framework after a small modification. I'm wondering if it is possible to reduce number of rebuilt components after modifying dalvik libcore? Thanks.

  • How to change PHP's eregi to preg_match

    - by jasondavis
    I need help, below is a small VERY basic regex to somewhat validate an email, I do realize it does not work the greatest but for my needs it is ok for now. It currently uses PHP's eregi function which php.net says is now a depreciated function and I should use preg_match instead, simply replacing erei with preg_match does not work, can someone show me how to make it work? function validate_email($email) { if (!eregi("^[[:alnum:]][a-z0-9_.-]*@[a-z0-9.-]+\.[a-z]{2,4}$", $email)) { echo 'bad email'; } else { echo 'good email'; } } function validate_email($email) { if (!preg_match("^[[:alnum:]][a-z0-9_.-]*@[a-z0-9.-]+\.[a-z]{2,4}$", $email)) { echo 'bad email'; } else { echo 'good email'; } }

  • iPhone MVC Question

    - by HM1
    Hi, I'm bit of a newbie and had a basic question regarding adhering to the MVC model in iPhone coding. How do I setup a Model class that holds my data and connect it to different controllers in the following setup: Using Interface Builder, I created a tab controller in which - Tab #1 has a Nav Controller and a hierarchy of View Controllers. - Tab #2 has a View Controller So with what I have now, the View Controller under Tab #1 alloc init's the model class and I know how to pass the model from one ViewController to the next in the Navigation Hierarchy where it can pass the data and/or be updated with new data. Question is how to pass it from Tab #1's View Controller to Tab #2 View Controller as there is no code linking the two??? Thanks in advance, Hiren.
