Using sw As New System.IO.StreamWriter("path\to\file.txt") sw.WriteLine("Hello world") End Using The use of a Using block is recommended good practice when using an object that Implements IDisposable

std::ifstream f("file.txt"); if (f) { std::stringstream buffer; buffer << f.rdbuf(); f.close(); // The content of "file.txt" is available in the string `buffer.str()` } The rdbuf() method returns a pointer to a streambuf that can be pushed into buffer...

/** * returns a array of random numbers with no duplicates * @param range the range of possible numbers for ex. if 100 then it can be anywhere from 1-100 * @param length the length of the array of random numbers * @return array of random numbers with no duplicates. */ public static int[] ...

Most times when people have to reverse a string, they do it more or less like this: char[] a = s.ToCharArray(); System.Array.Reverse(a); string r = new string(a); However, what these people don't realize is that this is actually wrong. And I don't mean because of the missing NULL check. It ...

Creating backpressured data sources is the relatively easier task when dealing with backpressure in general because the library already offers static methods on Observable that handle backpressure for the developer. We can distinguish two kinds of factory methods: cold "generators" that ei...

Conceptually, integrate 3rd party REST APIs can be as simple as adding the http package and making a call to the external endpoint. meteor add http HTTP.get('http://foo.net/api/bar/');

Basic HTTP calls don't provide code-reusability, however. And they can get confused with all the other features you're trying to implement. For those reasons, it's common to implement an API wrapper. Foo = { identify: function(input){ return Http.get('http://foo.net/api/identify/' + input...

After creating an API wrapper, it's likely that you may want to create an Atmosphere package to redistribute it and share it between applications. The files of your package will probably look something like this. packages/foo-api-wrapper/package.js packages/foo-api-wrapper/readme.md packages/foo-...

At this point, you're still building your package, so you'll need to add the package to your application: meteor add myaccount:foo And eventually publish it to Atmosphere: meteor publish myaccount:foo

Now that we have all those pieces put together, you should now be able to make calls like the following from within your app: Foo.identify('John'); Foo.record_action_on_item('view', "HackerNews'); Obviously you'll want to adjust function names, arguments, urls, and the like, to create the ...

The following scripts are for uploading a file from the server filesystem into the server. Mostly for config files and filewatchers. //https://forums.meteor.com/t/read-file-from-the-public-folder/4910/5 // Asynchronous Method. Meteor.startup(function () { console.log('starting up'); ...

Add React to your project: meteor npm install --save react react-dom react-mounter Create the client/helloworld.jsx file to display a simple React component: import React, { Component } from 'react'; import { mount } from 'react-mounter'; // This component only renders a paragraph containin...

It's possible to send broadcast to BroadcastReceiver with adb. In this example we are sending broadcast with action com.test.app.ACTION and string extra in bundle 'foo'='bar': adb shell am broadcast -a action com.test.app.ACTION --es foo "bar" You can put any other supported type to b...

We can also use macros for making code easier to read and write. For example we can implement macros for implementing the foreach construct in C for some data structures like singly- and doubly-linked lists, queues, etc. Here is a small example. #include <stdio.h> #include <stdlib.h>...

def str = 'nice' assert "Groovy is $str" == 'Groovy is nice'

def str = 'old' def interpolated = "I am the ${str} value" assert interpolated == 'I am the old value' str = 'new' assert interpolated == 'I am the old value'

We can have lazy interpolation in Strings. This is different than normal interpolation as the GString can potentially have different values, depending on the closure, whenever it is converted into a String. def str = 'old' def interpolated = "I am the ${ -> str} value" assert interpo...

<style name="AppTheme" parent="Theme.AppCompat"> <item name="android:colorEdgeEffect">@color/my_color</item> </style>

5.0 The ripple animation is shown when user presses clickable views. You can use the same ripple color used by your app assigning the ?android:colorControlHighlight in your views. You can customize this color by changing the android:colorControlHighlight attribute in your theme: This effect colo...

This attribute can change the background of the Status Bar icons (at the top of the screen) to white. <style name="AppTheme" parent="Theme.AppCompat"> <item name="android:windowLightStatusBar">true</item> </style>
