Okay it took me about a day to figure it out so here I am posting the steps I followed to get my Database First working in a Class Project (.NET Core), with a .NET Core Web App. Step 1 - Install .NET Core Make Sure you are using .NET Core not DNX (Hint: You should be able to see the .NET Core opti...

This serializer has some nice features that the default .net json serializer doesn't have, like Null value handling, you just need to create the JsonSerializerSettings : public static string Serialize(T obj) { string result = JsonConvert.SerializeObject(obj, new JsonSerializerSettings { NullVa...

Another way of doing aggregations is by using the Mongo.Collection#rawCollection() This can only be run on the Server. Here is an example you can use in Meteor 1.3 and higher: Meteor.methods({ 'aggregateUsers'(someId) { const collection = MyCollection.rawCollection() const aggre...

You can quickly determine if a text includes a specific pattern using Regex. There are multiple ways to work with Regex in PowerShell. #Sample text $text = @" This is (a) sample text, this is a (sample text) "@ #Sample pattern: Content wrapped in () $pattern = '\(.*?\)' Using ...

Sometimes you need to replace a value matching a pattern with a new value that's based on that specific match, making it impossible to predict the new value. For these types of scenarios, a MatchEvaluator can be very useful. In PowerShell, a MatchEvaluator is as simple as a scriptblock with a singl...

Tuples are immutable ordered collections of arbitrary distinct objects, either of the same type or of different types. Typically, tuples are constructed using the (x, y) syntax. julia> tup = (1, 1.0, "Hello, World!") (1,1.0,"Hello, World!") The individual objects of a tup...

Because Julia function parameter lists are themselves tuples, dispatching on various kinds of tuples is often easier done through the method parameters themselves, often with liberal usage for the "splatting" ... operator. For instance, consider the implementation of reverse for tuples, fr...

The IIF statement can be used in expressions to screen for division by zero: =IIF(Fields!PossibleZero.Value=0,0,Fields!Denominator.Value/IIF(Fields!PossibleZero.Value=0,1,Fields!PossibleZero.Value)) SSRS does not short circuit IIF arguments. Therefore, using a single IIF function to screen for ...

In order to use a plain-text editor to create a Console application that is written in C#, you'll need the C# Compiler. The C# Compiler (csc.exe), can be found at the following location: %WINDIR%\Microsoft.NET\Framework64\v4.0.30319\csc.exe N.B. Depending upon which version of the .NET Framework t...

The simplest manner of defining custom behavior for individual routes would be fairly easy. In this example we use it to authenticate a user : 1) routes.js: create a new property (like requireAuth) for any desired route angular.module('yourApp').config(['$routeProvider', function($routeProvider) ...

This example attempts to mimic the behavior of the built-in path construction operators like arc. If there is a current point, poly first draws a line to (x,y)+(r,0), otherwise it starts by moving to that point. Instead of gsave ... grestore (which has the undesirable effect of discarding the very...

This snippet dumps the contents of the current path to stdout. It uses the ghostscript procedure =only which may not be available on all interpreters. An equivalent procedure on Adobe interpreters is called =print. pathforall is a looping operator which takes 4 procedure bodies as arguments which a...
