Any declaration (variable, const, function, class, etc.) can be exported from module to be imported in other module. Typescript offer two export types: named and default. Named export // adams.ts export function hello(name: string){ console.log(`Hello ${name}!`); } export const answerToLi...

The only place where you can safely use async void is in event handlers. Consider the following code: private async Task<bool> SomeFuncAsync() { ... await ... } public void button1_Click(object sender, EventArgs e) { var result = SomeFuncAsync().Result; SomeOtherFunc(); } ...

Executes a OS-command. OS-COMMAND without any options will start a new shell and not exit it - thus you will on graphical OS:es leave a window "hanging". DEFINE VARIABLE cmd AS CHARACTER NO-UNDO. cmd = "dir". OS-COMMAND VALUE(cmd). There are three options: SILENT, NO...

Generate a random letter between a and z by using the Next() overload for a given range of numbers, then converting the resulting int to a char Random rnd = new Random(); char randomChar = (char)rnd.Next('a','z'); //'a' and 'z' are interpreted as ints for parameters for Next()

Executable C++ program code is usually produced by a compiler. A compiler is a program that translates code from a programming language into another form which is (more) directly executable for a computer. Using a compiler to translate code is called compilation. C++ inherits the form of its compi...
