    - by K-Bell
    I new to NUnit and looking for an explination as to why this test fails? I get the following exception when running the test. NUnit.Framework.AssertionException: Expected: equivalent to < <....ExampleClass, <....ExampleClass But was: < <....ExampleClass, <....ExampleClass using NUnit.Framework; using System.Collections.ObjectModel; public class ExampleClass { public ExampleClass() { Price = 0m; } public string Description { get; set; } public string SKU { get; set; } public decimal Price { get; set; } public int Qty { get; set; } } [TestFixture] public class ExampleClassTests { [Test] public void ExampleTest() { var collection1 = new Collection<ExampleClass> { new ExampleClass {Qty = 1, SKU = "971114FT031M"}, new ExampleClass {Qty = 1, SKU = "971114FT249LV"} }; var collection2 = new Collection<ExampleClass> { new ExampleClass {Qty = 1, SKU = "971114FT031M"}, new ExampleClass {Qty = 1, SKU = "971114FT249LV"} }; CollectionAssert.AreEquivalent(collection1, collection2); } }

  • PHP preg_replace - Very quick question

    - by RC
    Masters of regular expressions, please help! See this string: $string = "http://www.url.com/?fieldA=123&fieldB=456&fieldC=789"; Assuming "fieldB" always has a positive non-decimal numerical value (but not necessarily three digits long), what preg_replace command do I need to remove it completely, such that the string will then read: $string = "http://www.url.com/?fieldA=123&fieldC=789"; Thanks!

  • Matlab Question - Principal Component Analysis

    - by Jack
    I have a set of 100 observations where each observation has 45 characteristics. And each one of those observations have a label attached which I want to predict based on those 45 characteristics. So it's an input matrix with the dimension 45 x 100 and a target matrix with the dimension 1 x 100. The thing is that I want to know how many of those 45 characteristics are relevant in my set of data, basically the principal component analysis, and I understand that I can do this with Matlab function processpca. Could you please tell me how can I do this? Suppose that the input matrix is x with 45 rows and 100 columns and y is a vector with 100 elements.

  • Database Design Question: GUID + Natural Numbers

    - by Alan
    For a database I'm building, I've decided to use natural numbers as the primary key. I'm aware of the advantages that GUID's allow, but looking at the data, the bulk of row's data were GUID keys. I want to generate XML records from the database data, and one problem with natural numbers is that I don't want to expose my database key's to the outside world, and allow users to guess "keys." I believe GUID's solve this problem. So, I think the solution is to generate a sparse, unique iD derived from the natural ID (hopefully it would be 2-way), or just add an extra column in the database and store a guid (or some other multibyte id) The derived value is nicer because there is no storage penalty, but it would be easier to reverse and guess compared to a GUID. I'm (buy) curious as to what others on SO have done, and what insights they have.

  • Question about using awk to print all columns great then nth

    - by Andy
    right now I have this line, and it worked until I had whitespace in the second field. svn status | grep '\!' | gawk '{print $2;}' > removedProjs is there a way to have awk print everything in $2 or greater? ($3, $4.. until we don't have anymore columns?) I suppose I should add that I'm doing this in a windows environment with cygwin.

  • Multi-threaded downloader in C# question

    - by blez
    Currently I have multi-threaded downloader class that uses HttpWebRequest/Response. All works fine, it's super fast, BUT.. the problem is that the data needs to be streamed while it's downloading to another app. That means that it must be streamed in the right order, the first chunk first, and then the next in the queue. Currently my downloader class is sync and Download() returns byte[]. In my async multi-threaded class I make for example, list with 4 empty elements (for slots) and I pass each index of the slot to each thread using the Download() function. That simulates synchronization, but that's not what I need. How should I do the queue thing, to make sure the data is streamed as soon as the first chunk start downloading.

  • manyToManyField question

    - by dotty
    Hay guys, I'm writing a simple app which logs recipes. I'm working out my models and have stumbled across a problem My Dish models needs to have many Ingredients. This is no problem because i would do something like this ingredients = models.ManyToManyfield(Ingredient) No problems, my dish now can have many ingrendients. However, the problem is that the ingredient needs to come in different quantities. I.E 4 eggs, 7 tablespoons sugar My Ingredient Model is very simple at the moment class Ingredient(models.Model): name = models.TextField(blank=False) slug = models.SlugField(blank=True) How would i go about work out this problem? What fields would i need to add, would i need to use a 'through' attribute on my ManyToManyfield to solve this problem?

  • Question about variable definitions in functions.

    - by Kaan Tekelioglu
    Hi. #include <stdio.h> main() { int a; for(a=1; a<=4 && printf("%d ",a); a++) { int a; static int b=a; printf("%d ",(a++)-b); } getchar(); getchar(); } In this code, the printout is 1 0 2 1 3 2 4 3. I understand why the int a; part works differently then the int a which was defined outside the for function, and why static int b; is only defined once with the primary value of a ; but why does the (a++) part in printf affect proceeding values of a? Don't we redefine int a; each time the for function runs? Thanks in advance.

  • Regex Question..

    - by Josh
    Hello everyone- In my C# Console App I'm trying to use Regex to search a string to determine if there is a match or not. Below is my code but it is not quite working right so I will explain further. sSearchString is set to "_One-Call_Pipeline_Locations" and pDS.Name is a filename it is searching against. Using the code below it is set to true for Nevada_One-Call_Pipeline_Locations and Nevada_One-Call_Pipeline_LocationsMAXIMUM. There should be a match for Nevada_One-Call_Pipeline_Locations But Not for Nevada_One-Call_Pipeline_LocationsMAXIMUM. How can I change my code to do this properly? Thanks in advance if (Regex.IsMatch(pDS.Name, sSearchString))

  • Twitter Search API Question

    - by supermogx
    I'm using the twitter search API to get twitter posts based on some keywords, using AND and OR keyword. It works OK, but I seem to get problems using hashtags... For example : Not returning any results : http://search.twitter.com/search.json?q="%23ipad+AND+%23ipod"+OR+"%23joke+AND+%23funny"&rpp=100&callback=? Returning results : http://search.twitter.com/search.json?q="ipad+AND+ipod"+OR+"joke+AND+funny"&rpp=100&callback=? But there's results with #ipod AND #ipad because when I search only for #ipod, I can see a lot of posts with both hashtags. Example : http://search.twitter.com/search.json?q=%23ipad&rpp=100&callback=? P.S. %23 = # Any idea?

  • Javascript Closure question.

    - by Tony
    Why the following code prints "0-100"? (function () { for ( var i = 100; i >= 0; i -= 5) { (function() { var pos = i; setTimeout(function() { console.log(" pos = " + pos); }, (pos + 1)*10); })(); } })(); I declare pos = i , which should be in a descending order. This code originated from John Resig' fadeIn() function in his book Pro javascript techniques.

  • Sharepoint connected web parts question

    - by philj
    I have one web part (the provider) which displays insurance claims in a gridview. When user clicks on one this value(case number) is passed via IWebPartField interface to another web part(consumer) which displays detailed info about the claim. So far so good. I can select different claims in the provider and the details show up in the consumer just fine. The moment I add a TextBox to the consumer, the consumer no longer recognizes the case number passed. I need the user to be able to enter a value in the textbox and click a button to update that claim info. I can debug and attach to process and it looks like it is getting the case in the callback function, etc, but when it is setting parameters for the stored proc in CreateChildControls, it is null. Comment out the TextBox and it works fine. Any clues as to what is going on? Brand new to Sharepoint web parts...any help appreciated! thanks, PhilJ

  • C++ - Basic WinAPI question

    - by HardCoder1986
    Hello! I am now working on a some sort of a game engine and I had an idea to put everything engine-related into a static library and then link it to my actual problem. Right now I achieved it and actually link that library and every functions seem to work fine, except those, which are windows-related. I have a chunk of code in my library that looks like this: hWnd = CreateWindow(className, "Name", WS_OVERLAPPED | WS_CAPTION | WS_EX_TOPMOST, 0, 0, 800, 600, NULL, NULL, GetModuleHandle(NULL), this); if (hWnd) { ShowWindow(hWnd, SW_NORMAL); UpdateWindow(hWnd); } else { MessageBox(NULL, "Internal program error", "Error", MB_OK | MB_ICONERROR); return; } When this code was not in the library, but in the actual project, it worked fine, created the window and everything was ok. Right now (when I'm linking to my library that contains this code) CreateWindow(...) call returns NULL and GetLastError() returns "Operation succesfully completed" (wtf?). Could anybody help me with this? Is it possible to create a window and display it using a static library call and why could my code fail? Thank you.

  • HttpHandler with Flash file upload question

    - by Projapati
    I have a flash file uploader that allows uploading multiple files in one shot. Now on one click how many times will the hanlder is supposed to be called? I am seeing that the ProcessRequest() of the HttpHandler is getting called for each of the files I upload. If I upload 5 files, then the Process request gets called 5 times. This seems odd. I would expect the handler to be called just once where I will loop the Can anyone confirm this behavior or I am missing something?
