There are times when it is necessary to accept input as a string, yet you may need to take a value from that string and convert it into an integer for calculations. This is a very common practice in Java programming.

This tutorial will teach you how to create a blend effect in your windows form or a transparency/opacity of the form using vb.net. This will use "user32" library of our computer system so that it will take effect. Now, let's start this tutorial! 1. Let's start with creating a Windows Form Application for this tutorial by following the following steps in Microsoft Visual Studio: Go to File, click New Project, and choose Windows Application. 2. Create only a Form in your project. Insert also a Timer on it.

This tutorial covers creating a calculator to convert between Celsius (centigrade), Kelvin, and Fahrenheit. The user is first given the choice of which temperature unit they would like to convert from, and then they are given the results of the conversion. When different units are in use, things can get confusing. It is useful to have a calculator on hand for this sort of thing. Luckily, we can make one in Java that is able to do just that.

Previously, we covered how to use arrays in Java. If you are unfamiliar with arrays, please read through the first tutorial on arrays here. Two dimensional arrays are used to hold numbers that correspond to one another. One dimensional arrays can be thought of as a collection of variables listed in an indefinite number of rows, but a single column. Two dimensional arrays allow for both indefinite rows and columns.

This is a continuation of my other yutorial named File Watcher - Allow or Disallow Creating Files or Folder in VB.NET, but in this tutorial it will grant to rename or disallow renaming of files and folder using vb.net. Now, let's start this tutorial! 1. Let's start with creating a Windows Form Application for this tutorial by following the following steps in Microsoft Visual Studio: Go to File, click New Project, and choose Windows Application. 2.

This tutorial will teach you how to create a program that will use the File Watcher component allowing files or disallow creating files or folder in vb.net. Now, let's start this tutorial! 1. Let's start with creating a Windows Form Application for this tutorial by following the following steps in Microsoft Visual Studio: Go to File, click New Project, and choose Windows Application. 2. Next, add FileSystemWatcher in the form.

First, let's take a look at a simple "Hello, world!" program from last time.

Often times, computer programs are used as a study method by educators. In this program, many of the concepts we have gone over thus far are put together to make a working quiz that asks math questions, and returns results on how the user did. For this program, the user is asked how many math questions they would like. It generates random math questions with numbers 1 through 10, and randomly selects between addition, subtraction, multiplication. and division. If the user is right, it will tell them so.
