1. THE FORM

   • The form is the first object or control that is displayed in Visual Basic and constitutes the screen or window over which other objects or controls are placed such as labels, text controls, buttons, etc. and of course the necessary code of our programs, therefore will constitute the User Interface.

2. TOOLBOX

   • The Toolbox window displays controls that you can add to Visual Studio projects. To open Toolbox, choose Toolbox on the View menu. You can drag and drop different controls onto the surface of the designer you are using, and resize and position the controls. Toolbox appears in conjunction with designer views, such as the designer view of a XAML file. Toolbox displays only those controls that can be used in the current designer. You can search within Toolbox to further filter the items that appear.

3. TYPE OF DATA

   • There are 12 different types of data with which you can work, Dim Numero As Integer, Boolean, Byte, Double, Integer, Integer, Decimal, Single, String, Currency, Date, Object, Variant.

4. CONTROLS

   • The common Visual Basic controls are within the Visual Basic executable file. Intrinsic controls are always included in the toolbox, not like ActiveX controls and plug-ins, which can be removed or added to the toolbox.

5. OBJECT PROPRERTIES

   • An important goal of many of the object-oriented programming languages ​​is to allow you to encapsulate internal details in a class. Visual Basic .NET or Visual Basic 2005 allows you to define properties to provide controlled access to internal details in a class. This article describes how you can define and use properties in a Visual Basic .NET or Visual Basic 2005 application. A property can be read-only, write-only, or read / write. A Get accessor provides read access and a Set access, write access. You can add code to these accessors to provide the appropriate functionality to obtain or set the property. In this article, create a class calledEmployee . Within this class, define a read / write property for the employee's name, a reading property for the employee's salary, and a property to calculate how long the employee has been working for the company. Next, create an Employee object in your application and use its properties.

6. Control structures

   • they are used to control the flow of the program in a routine or function. These structures allow to control, by a condition, the execution or not of a line or set of lines or code.
