Object-Oriented Programming with Visual Basic .NET

Visual Basic .NET and Object-Oriented Programming
Visual Basic .NET is a fully object-oriented programming language, which means it supports the four basic tenets of object-oriented programming: abstraction, encapsulation, inheritance, and polymorphism. We have already conceptualized many of these object-oriented concepts by just looking at the objects that surround us in our everyday lives. Let’s look more closely at these terms and see what they actually mean and what they do for developers of object-oriented software.

Abstraction
A radio has a tuner, an antenna, a volume control, and an on/off switch. To use it, you don’t need to know that the antenna captures radio frequency signals, converts them to electrical signals, and then boosts their strength via a high-frequency amplification circuit. Nor do you need to know how the resulting current is filtered, boosted, and finally converted into sound. You merely turn on the radio, tune in the desired station, and listen. The intrinsic details are invisible. This feature is great because now everyone can use a radio, not just people with technical know-how. Hiring a consultant to come to your home every time you wanted to listen to the radio would become awfully expensive. In other words, you can say that the radio is an object that was designed to hide its complexity. […]

The Best Internet Blackjack Casinos

How We Determined the Best Internet Blackjack Casinos
There are over 3,000 Internet Casinos, with more being launched every day. Because of stiff competition these casinos are becoming more and more competitive. For example, offering bonuses for signing up or even returning after a brief absence is becoming more and more common.

Of course, a casino can offer all kinds of inducements, but if it fails to deliver, then they are worthless. We decided to use several major criteria to find the best online casinos for blackjack play. First, the games had to offer the lowest odds against the players. Casinos offering games with certain unfavorable variations, such as using the European no hole-card rule, were rejected.

Besides offering a favorable game, the casino had to be safe and reliable. Here we looked to the following criteria in picking the best online blackjack casinos:

  1. The software company standing behind the casino.

PayPal Sandbox User Guide

The PayPal Sandbox is a self-contained environment within which you can prototype and test PayPal features and APIs. The PayPal Sandbox is an almost identical copy of the live PayPal website. Its purpose is to give developers a shielded environment for testing and integration purposes and to help avoid problems that might occur while testing PayPal integration solutions on the live site. Before moving any PayPal-based application into production, you should test the application in the Sandbox to ensure that it functions as you intend and within the guidelines and standards set forth by the PayPal Developer Network (PDN).

Adobe Photoshop Panel Developer’s Guide

Introduction
Adobe ® Photoshop ® CS4 software has added a new feature to allow SWF files to run as a panel inside the digital imaging program. This document describes the process of creating such a panel. The Adobe Photoshop interface can be overwhelming for both new and seasoned users of the digital imaging program. The Adobe Photoshop Panel Developer’s Guide will teach developers how to develop custom panels to run within Adobe Photoshop CS4. The developer community can develop panels to allow other users to use for their own custom needs. Some ideas of this concept include:

  • Workflow Panels: Developers can create custom panels meeting the workflow of any work environment.
  • Video Training: Developers can create video feeds that would teach others how to use Adobe Photoshop.
  • Browsing Exchange: Developers can create a custom browser to exchange files and data from web sites, photo galleries,databases and load them directly into Adobe Photoshop.
  • Peer-to-Peer Exchange: Developers can interact with other developers to communicate and exchange ideas and data.

Who Should Read This?
The Adobe Photoshop Panel Developer’s Guide is geared towards those with experience in one or more of the following groups:

  • Adobe Flash
  • Adobe Flex Builder
  • Adobe Photoshop with some programming background
  • Object-Oriented Programming such as Java or C++
  • Scripting such as JavaScript, AppleScript, or ActionScript

For those who are experienced with Adobe Photoshop but have little exposure to programming, please refer to the Adobe Photoshop Developer Center. For those who do not fall into any of the groups, please refer to the Links section for other listed tutorials, resources, and books to prepare for the Adobe Photoshop Panel Developer’s Guide.
