Creating a Simultaneous Equations Solver in Visual Basic 6

You can create many practical Visual Basic applications in solving secondary school mathematics. Among them is simultaneous equations. You can create Visual Basic applications to solve linear simultaneous equations and non-linear simultaneous equations. Simultaneous equations are equations that involves two or more unknown variables. There must be as many equations as the number of unknown variables in order for us to solve the problem.

We have written two simultaneous equations solver using Visual Basic 6, one is linear and the other one is non-linear. learn more by following the links below:

Using Variables and Constants in Visual Basic 2015

In Visual Basic 2015 programming, we have to deal with all kinds of data. The data could be numbers, strings, time, currency and more. How do we store data then? In Visual Basic 2015, data can be stored as variables or as  constants. Variables are like mail boxes in the post office. The content of the variable changes every now and then, just like the mail boxes. In  Visual Basic 2015, variables are created in the specific areas allocated by the computer memory to store data.

Dealing with Data in Visual Basic 2015

In Visual Basic 2015 programming, we need to deal with all sorts of of data, some of them can be mathematically calculated while some are in the form of text or other non-numeric forms. Data can be stored as variables, constants or arrays. The values of data stored as variables always change, just like the contents of a mail box or the storage bin while the value of a constant remains the same throughout.

Working with Picture Box in Visual Basic 2015

Picture box is a control in Visual Basic 2015 that is used to display images .In Visual Basic 2015 Tutorial Lesson lesson 3, we have already learned how to insert a picture box on the form in Visual Basic 2015. However, we have not learned how to load a picture in the picture box yet. In this lesson, we shall learn how to load an image into the picture box at design time and at runtime. Besides that, we shall also learn how to using a common dialog control to browse for image files in your local drives and then select and load a particular image in the picture box.
