Consider using Extension Methods as Functions which wrap other code, here's a great example that uses both a static method and and extension method to wrap the Try Catch construct. Make your code Bullet Proof... using System; using System.Diagnostics; namespace Samples { /// <summary&g...

Database connections are set up using the CF Administrator tool. See Database Connections for how to connect a datasource. To execute queries all you need is the <cfquery> tag. The <cfquery> tag connects to and opens the database for you, all you need to do is supply it with the name of...

A cached query is a query that has its results stored in the server's memory. The results are stored when the query is first run. From then on, whenever that query is requested again, ColdFusion will retrieve the results from memory. You can cache a query using the cachedAfter attribute. If the que...

You can limit the number of rows to be returned by using the maxrows attribute. <cfquery datasource="Entertainment" maxrows="50"> select * from Movies </cfquery>

You can set a timeout limit using the timeout attribute. This can be useful in preventing requests running far longer than they should and impacting on the whole application as a result. The timeout attribute sets the maximum number of seconds that each action of a query is allowed to execute befor...

If you want to make internal classes or functions of an assembly accessable from another assembly you declare this by InternalsVisibleTo and the assembly name that is allowed to access. In this example code in the assembly MyAssembly.UnitTests is allowed to call internal elements from MyAssembly. ...

Virtual Methods are methods in Java that are non-static and without the keyword Final in front. All methods by default are virtual in Java. Virtual Methods play important roles in Polymorphism because children classes in Java can override their parent classes' methods if the function being overriden...

Structures in Rust are defined using the struct keyword. The most common form of structure consists of a set of named fields: struct Foo { my_bool: bool, my_num: isize, my_string: String, } The above declares a struct with three fields: my_bool, my_num, and my_string, of the type...

Consider the following struct definitions: struct Foo { my_bool: bool, my_num: isize, my_string: String, } struct Bar (bool, isize, String); struct Baz; Constructing new structure values for these types is straightforward: let foo = Foo { my_bool: true, my_num: 42, my_string: ...

To declare methods on a struct (i.e., functions that can be called "on" the struct, or values of that struct type), create an impl block: impl Foo { fn fiddle(&self) { // "self" refers to the value this method is being called on println!("fiddling...

Structures can be made generic over one or more type parameters. These types are given enclosed in <> when referring to the type: struct Gen<T> { x: T, z: isize, } // ... let _: Gen<bool> = Gen{x: true, z: 1}; let _: Gen<isize> = Gen{x: 42, z: 2}; let _: Gen...

async and await are two operators that are intended to improve performance by freeing up Threads and waiting for operations to complete before moving forward. Here's an example of getting a string before returning it's length: //This method is async because: //1. It has async and Task or Task<...

C.I.A.s are intended as a simple way of getting attributes from whatever is calling the targeted method. There is really only 1 way to use them and there are only 3 attributes. Example: //This is the "calling method": the method that is calling the target method public void doProcess() ...

Lambda expressions are similar to anonymous functions in other languages. Lambda expressions are open formulas which also specify variables which are to be bound. Evaluation (finding the value of a function call) is then achieved by substituting the bound variables in the lambda expression's body, ...

[TimeStamp] attribute can be applied to only one byte array property in a given Entity class. Entity Framework will create a non-nullable timestamp column in the database table for that property. Entity Framework will automatically use this TimeStamp column in concurrency check. using System.Compon...

Function scope is the special scope for labels. This is due to their unusual property. A label is visible through the entire function it is defined and one can jump (using instruction gotolabel) to it from any point in the same function. While not useful, the following example illustrate the point: ...
