The random() function can be used to generate pseudo-random numbers: void setup() { Serial.begin(9600); } void loop() { long randomNumber = random(500); // Generate a random number between 0 and 499 Serial.println(randomNumber); randomNumber = random(100, 1000); // Genera...

With TypeScript 1.8 it becomes possible for a type parameter constraint to reference type parameters from the same type parameter list. Previously this was an error. function assign<T extends U, U>(target: T, source: U): T { for (let id in source) { target[id] = source[id]; ...

composer update composer update will update our dependencies as they are specified in composer.json. For example, if our project uses this configuration: "require": { "laravelcollective/html": "2.0.*" } Supposing we have actually installed the 2.0.1 version ...

Below are the operators that can be overloaded in classes, along with the method definitions that are required, and an example of the operator in use within an expression. N.B.

For performance reasons you should minimize the number of fields you are requesting from the API. You can use the select property to do so. This example fetches the name property of all accounts: $.ajax({ url: Xrm.Page.context.getClientUrl() + '/api/data/v8.0/accounts?$select=name', head...

If you fetch a single record and when that record has a lookup, you can also fetch values of the lookup value using the expand option. This reduces the number of calls you need to make to the API. The sample gets all accounts and the last name of the primary contact: $.ajax({ url: Xrm.Page.co...

This sample fetches accounts using a jQuery ajax method. On thing to note is that you need to set the header in the call to make the work. $.ajax({ url: Xrm.Page.context.getClientUrl() + '/api/data/v8.0/accounts', headers: { 'Accept': 'Application/json' } }).done(function...

You can use the filter property to retrieve a subset of values from CRM. In this example only the accounts where the company name equals CompanyName are returned. $.ajax({ url: Xrm.Page.context.getClientUrl() + '/api/data/v8.0/accounts?$filter=name eq CompanyName', headers: { 'A...

It is possible to write a method on a generic type that is more restrictive using where sentence. extension Array where Element: StringLiteralConvertible { func toUpperCase() -> [String] { var result = [String]() for value in self { result.append(String(value).upperca...

PROGRAM zhello_world. START-OF-SELECTION. WRITE 'Hello, World!'. Instead of printing to the console, ABAP writes values to a list which will be displayed as soon as the main logic was executed.

ABAP Classes can be declared Globally or Locally. A global class can be used by any object within the ABAP repository. By contrast, a local class can only be used within the scope it is declared. CLASS lcl_abap_class DEFINITION. PUBLIC SECTION. PROTECTED SECTION. PRIVATE SECTION. ENDCLASS...
