angular.component("SampleComponent", {
bindings: {
title: '@',
movies: '<',
reservation: "=",
processReservation: "&"
}
});
Here we have all binding elements.
@ indicates that we need a very basic binding, from the parent scope ...
The next example can be used to determine whether a enumeration has the FlagsAttribute specified. The methodology used is based on Reflection.
This example will give a True result:
Dim enu As [Enum] = New FileAttributes()
Dim hasFlags As Boolean = enu.GetType().GetCustomAttributes(GetType(FlagsAt...
In some very specific scenarios we would feel the need to perform a specific action for each flag of the source enumeration.
We can write a simple Generic extension method to realize this task.
<DebuggerStepThrough>
<Extension>
<EditorBrowsable(EditorBrowsableState.Always)>
Pu...
The next example is intended to count the amount of flags in the specified flag combination.
The example is provided as a extension method:
<DebuggerStepThrough>
<Extension>
<EditorBrowsable(EditorBrowsableState.Always)>
Public Function CountFlags(ByVal sender As [Enum]) As In...
The next code illustrates how to find the nearest value of a Enum.
First we define this Enum that will serve to specify search criteria (search direction)
Public Enum EnumFindDirection As Integer
Nearest = 0
Less = 1
LessOrEqual = 2
Greater = 3
GreaterOrEqual = 4
End Enum...
There are a number of guidelines to follow when creating and using
header files in a C project:
Idemopotence
If a header file is included multiple times in a translation unit
(TU), it should not break builds.
Self-containment
If you need the facilities declared in a header file, you sh...
If a particular header file is included more than once in a translation unit (TU),
there should not be any compilation problems.
This is termed 'idempotence'; your headers should be idempotent.
Think how difficult life would be if you had to ensure that #include <stdio.h> was only included ...
Modern headers should be self-contained, which means that a program that needs to use the facilities defined by header.h can include that header (#include "header.h") and not worry about whether other headers need to be included first.
Recommendation: Header files should be self-contained...
Headers are a crucial consistency checking mechanism, but they should be
as small as possible.
In particular, that means that a header should not include other headers
just because the implementation file will need the other headers.
A header should contain only those headers necessary for a con...
Google's Include What You Use project, or IWYU, ensures source files include all headers used in the code.
Suppose a source file source.c includes a header arbitrary.h which in turn coincidentally includes freeloader.h, but the source file also explicitly and independently uses the facilities from ...
The C standard says that there is very little difference between the
#include <header.h> and #include "header.h" notations.
[#include <header.h>] searches a sequence of implementation-defined
places for a header identified uniquely by the specified sequence
between the &l...
If a singleshot timer is required, it is quiet handy to have the slot as lambda function right in the place where the timer is declared:
QTimer::singleShot(1000, []() { /*Code here*/ } );
Due to this Bug (QTBUG-26406), this is way is only possible since Qt5.4.
In earlier Qt5 versions it has to ...
The config location for your runner is:
Debian/Ubuntu/CentOS
/etc/gitlab-runner/config.toml if run as root
~/.gitlab-runner/config.toml if run as non-root
Windows
config.toml where your binary is located
A minimal config.toml can look like this:
concurrent = 1

Setup
First, install the necessary packages with:
npm install express cors mongoose
Code
Then, add dependencies to server.js, create the database schema and the name of the collection, create an Express.js server, and connect to MongoDB:
var express = require('express');
var cors = require('...
