Visual Basic 6.0 For Beginners

[Clinio Lofton]

VBNet is a simple, modern, object-oriented computer programming language developed by Microsoft to combine the power of .NET Framework and the common language runtime with the productivity benefits that are the hallmark of Visual Basic. This tutorial will teach you basic VB.Net programming and will also take you through various advanced concepts related to VB.Net programming language.

This tutorial has been prepared for the beginners to help them understand basic VB.Net programming. After completing this tutorial, you will find yourself at a moderate level of expertise in VB.Net programming from where you can take yourself to next levels.

VB.Net programming is very much based on BASIC and Visual Basic programming languages, so if you have basic understanding on these programming languages, then it will be a fun for you to learn VB.Net programming language.

Here, we will learn the Visual Basic (VB) tutorial with examples. In Visual Basic tutorial, we covered topics like vb operators, vb classes, vb static, vb partial classes, vb methods, vb arrays, vb collections, etc., for beginners and experienced with examples.

Visual Basic (VB) tutorial is prepared to help beginners and experienced people interested in learning and implementing the applications using .NET Framework with Visual Basic. We covered topics from basic to advanced in the Visual Basic tutorial, and those will give a clear idea of how to use Visual Basic in our applications with live examples.

Visual Basic for Application is a human-readable and editable programming code that gets generated when you record a macro. Today, it is widely-used with other Microsoft Office applications such as MS-Word, MS-Excel, and MS-Access.

Functions are the reusable code that can be called anywhere in the program. You can use the code over and over again in your program. To create the function in the VBA window, go to Insert > Module and it will create a new module.

This Business Analytics certification course teaches you the basic concepts of data analysis and statistics to help data-driven decision making. This training introduces you to Power BI and delves into the statistical concepts that will help you devise insights from available data to present your findings using executive-level dashboards.

Yes, Excel VBA is a valuable skill, especially for professionals working with data analysis, finance, or project management. It can significantly improve productivity and open up opportunities for more complex tasks.

The difficulty of learning Excel VBA depends on your programming background. For beginners, it may take some time to grasp the concepts, but with practice and resources, it can be learned effectively.

Yes, VBA is included for free in Excel. It is a built-in feature of Microsoft Excel and is available in all versions of Excel, including the Office 365 subscription. Users can start using VBA without additional cost.

The Google AlphaGO drew the attention of the entire world over the past few weeks, an artificial neural network shows its remarkable ability, with the deep learning technology, AlphaGO even beat one of the world's top go chess player.

Currently, the AI which makes us through him is a human who still exists only in the movies, as our world is too complex for the AI program to process. The world in a video game is a simplified version of our real world, we could not create a human like AI for the real world, but creating a player AI in the gaming world is possible.

As for me, my most joyful thing is playing a video game, and the Mario game is my most favorite as the NES game Mario brothers accompanied me in my childhood. A Mario game machine player MarI/O made by Seth Bling by using the evolutionary neuron network technology inspired me to step into the area of machine learning.

The Q-Learning is a kind of mode-free machine learning algorithm, and it is the most simple algorithm in the ML for machine-learning beginners like me. Generally, there are three steps in the Q-Learning in total:

At the QTable's initial state, there is no element in the QTable dictionary, but with the game continued playing, more and more environment states will be stored in the QTable, so that you can consider the QTable as one man's experience on doing something.

In this QL_AI snake game controller program, we are using the e-greedy approach algorithm to make a choice of the program of how to deal with current environment state: Trying a new exploration or action based on the previous experience:

As the description above, the algorithm core of the Q-Learning is the q-value (rewards and penalty) for the actions on a specific environment state applied to the QTable object, so that we should define an action object to represent the best action under a specific environment state:

For the class code definition above, we know that in the current environment state EnvirState, the program that has some action choice, which the action is encoded as the index in the Qvalues array, and the array elements in the Qvalues property represents the action rewards on the current state EnvirState, the higher value of the element in the Qvalues means the higher reward of the action on current state so that we just let the program return the index of the max value in the Qvalues, and this index can be decoded as the best action. Gets the best action in the current state just like the function actions below:

In this snake game, there are only just four direction keys on the program's joypad, so that the Qvalues property in the Action class has four elements, stands for the q-value of each direction button that the machine program presses.

As you can see in the __getBestAction function that is shown above, first, the program gets the q-value from current environment state, and then from the compares, the program he can choose an action index that would maximize the rewards in that direction.

For generating the experience of doing something for the program, a dictionary add method was implemented for adding the new environment state to the QTable, so that this makes it possible for the program to learn the new world.

For teaching a child, we often give some rewards when the kids are doing as we expect, so we did in the Q-Learning, we using the rewards to improving the program's experience on the action of the specific environment state:

If the program's action makes him approach our goal, then we update the actions q-value with rewards, if not, then we update the actions q-value with penalty score so that after several time training loops, the program will work as we expected. The Q-Learning just acts like the dog's classical conditioning.

This article just tries to explain the basic concepts of the machine learning from a most simple snake game, and I hope you could get ideas to build a more powerful AI program that can deal with more complex environment situation.

Instead this book almost feels like a fun journey through the world of Visual Basic to see what it can offer. Early chapters introduce VB and basic concepts like objects, events, and simple UI designs.

The overall style of this book is simplistic but accurate. It does not have many practical real-world scenarios you can follow, but if you apply the advice in this book with your own ideas you should be able to create some really cool stuff.

Using .NET you can either program over VB or C#, both of which are very powerful languages. Learning Visual Basic .Net is a book written for object-oriented programmers who want to dive into this incredible framework without much prior knowledge.

This is still in its 1st edition spanning 800 massive pages of recipes and cool problem/solution workflows. You can flip around to find anything you want to learn from arrays/collections to XML scanning and data parsing.

Professional Visual Studio 2017 is a complete guide to the interface and the IDE from a visual and programmatic perspective. The newest version of VS 2017 does come with some new features and this book covers all of those plus the classic techniques too.
