Methods used: .DriveExists(strDrive) returns (True/False) .FileExists(strFile) returns (True/False) .FolderExists(strFolder) returns (True/False) The following code checks for the existence of a file using the "FileExists" method of a file system object. For checking the existence of...

Methods used: .DeleteFolder(FileSpec, Force (True/False)) .CreateFolder(Path) .DeleteFile(FileSpec, Force (True/False)) The following example illustrates the Deletion and creation of a folder using the methods "DeleteFolder" and "CreateFolder". Code: Dim strFolderPath, ob...

Methods Used: .CopyFile(Source, Dest [,Overwrite (True/False)] .CopyFolder(Source, Dest [,Overwrite (True/False)] The following code illustrates the use of CopyFile method to copy a file to a new location. The same thing can be achieved for the folders by using the CopyFolder method. Code: Di...

Methods Used: .MoveFile(Source, Dest) .MoveFolder(Source, Dest) The following code illustrates the use of MoveFile method to Move a file to a new location. The same thing can be achieved for the folders by using the MoveFolder method. Code: Dim objFso, strSourcePath, strDestPath strSourcePat...

Methods used: .GetFolder(strPath) - Returns an object referring to the path We can set an object reference to a folder using the getFolder method and perform different operations on them. Code: Dim strFolderPath, objFso, objFolder strFolderPath = "C:\Users\GS\Desktop\LogsFolder" Se...

Methods Used: .GetFile(strPath) - Returns an object referring to a file. We can set an object reference to a file using the getFile method and perform different operations on them. Code: Dim strFilePath, objFso, objFile strFilePath = "C:\Users\GS\Desktop\LogsFolder\file.txt" Set ob...

As you would know, Hadoop can be run in the local environment in 3 different modes : Local Mode Pseudo Distributed Mode Fully Distributed Mode (Cluster) Typically you will be running your local hadoop setup in Pseudo Distributed Mode to leverage HDFS and Map Reduce(MR). However you cannot de...

As java provide two different commands to compile and run Java code. Same as Kotlin also provide you different commands. javac to compile java files. java to run java files. Same as kotlinc to compile kotlin files kotlin to run kotlin files.

This example shows how to customize the UIDynamicItem protocol to map position changes of a view being dynamically animated to bounds changes to create a UIButton that expands and contracts in a elastic fashion. To start we need to create a new protocol that implements UIDynamicItem but that also...

Redis-py provides the execute_command method to directly invoke Redis operations. This functionality can be used to access any modules that may not have a supported interface in the redis-py client. For example, you can use the execute_command to list all of the modules loaded into a Redis server:...

Numeric values can compared with = and the other numeric comparison operators (/=, <, <=, >, >=) that ignore the difference in the physical representation of the different types of numbers, and perform the comparison of the corresponding mathematical values. For instance: (= 42 42) T ;...

Common Lisp has 12 type specific operators to compare two characters, 6 of them case sensitives and the others case insensitives. Their names have a simple pattern to make easy to remember their meaning: Case SensitiveCase InsensitiveCHAR=CHAR-EQUALCHAR/=CHAR-NOT-EQUALCHAR<CHAR-LESSPCHAR<=CHA...

In Common Lisp there are many different predicates for comparing values. They can be classified in the following categories: Generic equality operators: EQ, EQL, EQUAL, EQUALP. They can be used for values of any type and return always a boolean value T or NIL. Type specific equality operators: =...

Foreword This is a detailed example about how to encrypt and decrypt data with Go. The uses code is shorten, e.g. the error handling is not mentioned. The full working project with error handling and user interface could be found on Github here. Encryption Introduction and data This example de...

The core idea is to use GameObjects to represent singletons, which has multiple advantages: Keeps complexity to a minimum but supports concepts like dependency injection Singletons have a normal Unity lifecycle as part of the Entity-Component system Singletons can be lazy loaded and cached loca...

We can use the componentchanged event to listen for changes to the entity: entity.addEventListener('componentchanged', function (evt) { if (evt.detail.name === 'position') { console.log('Entity has moved from', evt.detail.oldData, 'to', evt.detail.newData, '!'); } });

We can use the child-attached and child-detached events to listen for when the scene attaches or detaches an entity: entity.addEventListener('child-attached', function (evt) { if (evt.detail.el.tagName.toLowerCase() === 'a-box') { console.log('a box element has been attached'); }; }); ...

Updating Multi-Property Component Data To update component data for a multi-property component, we can pass the name of a registered component as the componentName, and pass an object of properties as the value. A string is also acceptable (e.g., type: spot; distance: 30), but objects will save A-F...

For example, if we wanted to grab an entity’s three.js camera object or material object, we could reach into its components var camera = document.querySelector('a-entity[camera]').components.camera.camera; var material = document.querySelector('a-entity[material]').components.material.material; ...

Systems can help separate logic and behavior from data if desired. We let systems handle the heavy lifting, and components only worry about managing its data through its lifecycle methods: AFRAME.registerSystem('my-component', { createComplexObject: function (data) { // Do calculations ...
