languages like C++). This thing has advantages (such as running the applications without compiling or the portability across platforms) and disadvantages (such as the need of a virtual machine to interpret the code) [10]. One of the primary roles of the Visual Basic language is that the user can create complex applications in a short period of time and he can use relatively simple dedicated computer systems (such as data bases – Visual Basic can use any systems of data base management known so far, directly or by using ODBC). The use of the Visual Basic language is a general one, being used for simple, educational applications but also for complex ones (such as games). Theoretically anybody (more or less experienced) can use Visual Basic because it‟s a simple programming language [10]. The primary role of the calculators is decreasing the working time. By taking out the time spent on doing calculations of the experimental data, the working time is decreased. The calculators made in Visual Basic are easy to use. The user types in the experimental data and by pressing a button he receives the final value instantly [3]. Another major role of these applications is that the user is able to save the experimental data and export it into an Excel table. By doing this he can use it later for other projects. We think that integrating this software in the laboratory physics lesson increases the lesson quality and develops the motivation for the experimental methods of matter investigation. II. BUILDING THE APPLICATIONS We will use one of the calculators (the “Minimum Deviation Experimental Method” calculator) in order to show you how it was created. The Graphic User Interface is presented below (Figure 1). Figure 1. The GUI for the “Minimum Deviation Experimental Method” 2.1 Designing the GUI (Graphic User Interface) We start by setting the window size in Visual Basic. Next we can edit the title, icon and the window properties (Figure 2).
Figure 2. The properties window. The toolbox. Any changes made in the “Properties” window will be written with bold font. The next step is using the Toolbox control (Figure 2). Insert one Picture Box (where we place a picture of the main formula – Figure 3) and add a picture in it: click on the picture box, go to properties (they‟re placed on the lower right corner of the screen, they look like the window properties where we changed the title - Figure 2) and then look for Background Image and browse the picture. Add six more Picture Boxes (for the other formulas – Figure 3). We use them instead of writing the formulas directly because they are all fractions. To write such a formula in Visual Basic means to draw lines. If we do this we end up having our application not working. It will not run on any other computer which doesn‟t have Visual Basic installed because Windows lacks some files (DLL files) needed to read the lines we‟ve drawn. Figure 3. The main formula. The other formulas.
