- This tutorial will help you understand the Visual Basic TextBox control and its important properties, methods and events. Name property: A unique name given to the textbox control on a windows Form. Usually 'txt' is the prefix used for textbox. For example, if you use a textbox to get customer's name, txtCustomer is the naming convention.

In this tutorial, Will see some basic string operation like how to print string and char in visual basic. Check the visual basic program for mathematical operations.
[Lesson 4]<< [CONTENTS] >> [Lesson 6]
In preceding lessons, you have learned some basic concepts of Visual Basic 2010 programming. In this lesson, we learn to write actual programs. We will keep the theories short so that it would not be too difficult for you.
5.1 The event Procedure
Visual Basic 2010 is an object-oriented and also a event-driven programming language. In fact, all windows applications are event-driven. Event-driven means the user decides what actions to take, like clicking a command button or entering text in a text box. An event is related to an object, it is an incident that happens to the object due to the action of the user, such as clicking the mouse or depressing a key on the keyboard. A class has events as it creates an instant of a class or an object.
When we launch Visual Basic 2010, we will see a default form with the Form1 appears in its IDE, it is actually the Form1 Class that inherits from the Form class System.Windows.Forms.Form, as shown in the Form1 properties windows.
Figure 5.1
When we click on any part of the form, we will see the code window as shown below. The is the structure of an event procedure. In this case, the event procedure is to load Form1 and it starts with Private Sub and ends with End Sub. This procedure includes the Form1 class and the event Load, and they are bound together with an underscore, i.e. Form_Load. It does nothing other than loading an empty form. You don’t have to worry the rest of the stuff at the moment, they will be explained in later lessons.
The are other events associated with the Form1 class, such as click, cursorChanged, DoubleClick, DragDrop, Enter and more as shown in the diagram below (It appears when you click on the upper right pane of the code window)
Figure 5.2
5.2 Writing the code
Super smash flash 2 mods no download. Now you are ready to write the code for the event procedure so that it will do something more than loading a blank form. The code must be entered between Private Sub…….End Sub. Let’s enter the following code:
Visual Basic Sample Projects
Cooling tech microscope 1600x software download. The first line of the code will change the title of the form to My First Visual Basic 2010 Program, the second line will change the foreground object to Forest Green( in this case, it is a label that you insert into the form and change its name to Foreground) and the last line changes the background to Cyan color.
The equal (=)in the code actually is used to assign something to the object, like assigning a yellow color to the foreground of the Form1 object (or an instance of Form1). Me is the name given to the Form1 class. We can also call those lines as Statements. So, the actions of the program will depend on the statements entered by the programmer.
The output is shown in Figure 5.1
Figure 5.1
Here is another example.
In this example, you insert one command button into the form and rename its caption as Show Hidden Names. The keyword Dim is to declare variables name1, name2 and name3 as a string, which means they can only handle text. The function MsgBox is to display the names in a message box that are joined together by the “&” signs. The output is shown in Figure 5.4
