To create your first Visual Basic project, follow these steps:
Launch Visual Studio from the Start menu or the desktop shortcut.
On the start window, click on Create a new project.
On the Create a new project window, type Visual Basic in the search box and select Windows Forms App (.NET Framework) from the list. Click on Next.
On the Configure your new project window, type MyFirstApp in the Project name box and choose a location to save your project. Click on Create.
You have just created your first Visual Basic project. You should see a blank form on the designer window and some code on the code editor window. The form is where you design your user interface and the code is where you write your program logic.
How to use variables, data types, operators, and expressions in Visual Basic
In this section, you will learn how to use variables, data types, operators, and expressions in Visual Basic. These are some of the basic elements of any programming language that allow you to store, manipulate, and evaluate data in your program.
A variable is a name that represents a value that can change during the execution of your program. For example, you can use a variable to store the name of a user, the score of a game, or the result of a calculation. To use a variable in Visual Basic, you need to declare it and assign it a value.
To declare a variable in Visual Basic, you use the Dim statement followed by the name of the variable and optionally its data type. A data type is a classification of data that specifies what kind of values a variable can hold and what operations can be performed on it. For example, you can use the Integer data type to store whole numbers and the String data type to store text.
Here are some examples of how to declare variables in Visual Basic:
Dim name As String 'declare a string variable named name
Dim age As Integer 'declare an integer variable named age
Dim pi As Double 'declare a double variable named pi
To assign a value to a variable in Visual Basic, you use the = operator followed by the value that you want to assign. The value can be a literal value (such as a number or a text) or an expression (such as a calculation or a function call). Here are some examples of how to assign values to variables in Visual Basic:
name = "Alice" 'assign the string "Alice" to the name variable
age = 25 'assign the number 25 to the age variable
pi = 3.14 'assign the number 3.14 to the pi variable
You can also declare and assign a variable in one statement using the Dim statement with an initializer. Here are some examples of how to do that in Visual Basic:
Dim name As String = "Alice" 'declare and assign a string variable named name
Dim age As Integer = 25 'declare and assign an integer variable named age
Dim pi As Double = 3.14 'declare and assign a double variable named pi
How to control the flow of your program using conditional statements and loops
In this section, you will learn how to control the flow of your program using conditional statements and loops. These are some of the essential structures of any programming language that allow you to execute different blocks of code based on certain conditions or repeat a block of code for a certain number of times or until a condition is met.
A conditional statement is a statement that evaluates a condition and executes one or more blocks of code depending on whether the condition is true or false. The most common conditional statement in Visual Basic is the If...Then...Else statement. The syntax of the If...Then...Else statement is as follows:
If condition Then
'block of code to execute if condition is true
Else
'block of code to execute if condition is false
End If
The condition can be any expression that evaluates to a Boolean value (True or False). The Else part is optional and can be omitted if there is no code to execute if the condition is false. You can also use multiple conditions and blocks of code using the ElseIf keyword. Here are some examples of how to use the If...Then...Else statement in Visual Basic:
Dim score As Integer = 80 'declare and assign an integer variable named score
If score >= 90 Then
Console.WriteLine("You got an A") 'print "You got an A" if score is greater than or equal to 90
ElseIf score >= 80 Then
Console.WriteLine("You got a B") 'print "You got a B" if score is greater than or equal to 80 but less than 90
ElseIf score >= 70 Then
Console.WriteLine("You got a C") 'print "You got a C" if score is greater than or equal to 70 but less than 80
Else
Console.WriteLine("You failed") 'print "You failed" if score is less than 70
End If
Dim name As String = "Bob" 'declare and assign a string variable named name
If name = "Alice" Then
Console.WriteLine("Hello Alice") 'print "Hello Alice" if name is equal to "Alice"
Else
Console.WriteLine("Who are you?") 'print "Who are you?" if name is not equal to "Alice"
End If
A loop is a statement that repeats a block of code for a certain number of times or until a condition is met. The most common loops in Visual Basic are the For...Next loop and the While...End While loop. The syntax of the For...Next loop is as follows:
For counter As Integer = start To end [Step increment]
'block of code to repeat
Next [counter]
The counter is a variable that holds the current value of the loop. The start and end are expressions that specify the initial and final values of the counter. The increment is an optional expression that specifies how much the counter changes each iteration. The default increment is 1. The Next statement marks the end of the loop and optionally specifies the counter variable. Here are some examples of how to use the For...Next loop in Visual Basic:
For i As Integer = 1 To 10 'declare and assign an integer variable named i from 1 to 10
Console.WriteLine(i) 'print i each iteration
Next i 'end the loop and specify i as the counter
For j As Integer = 10 To 1 Step -1 'declare and assign an integer variable named j from 10 to 1 with a decrement of -1
Console.WriteLine(j) 'print j each iteration
Next 'end the loop without specifying j as the counter
How to work with arrays, collections, and strings
In this section, you will learn how to work with arrays, collections, and strings in Visual Basic. These are some of the common data structures that allow you to store and manipulate multiple values in your program.
An array is a data structure that stores a fixed number of values of the same data type in a contiguous memory location. You can access the values in an array by using an index, which is a number that represents the position of the value in the array. The index starts from 0 for the first value and ends at n-1 for the last value, where n is the size of the array.
To declare an array in Visual Basic, you use the Dim statement followed by the name of the array and parentheses that specify the size of the array. You can also optionally specify the data type of the array. Here are some examples of how to declare arrays in Visual Basic:
Dim numbers(9) As Integer 'declare an integer array named numbers with 10 elements
Dim names(4) As String 'declare a string array named names with 5 elements
Dim colors() As String = "Red", "Green", "Blue" 'declare and initialize a string array named colors with 3 elements
To assign values to an array in Visual Basic, you use the = operator followed by the value that you want to assign. You can also use an initializer to assign values to an array when you declare it. Here are some examples of how to assign values to arrays in Visual Basic:
numbers(0) = 10 'assign the number 10 to the first element of the numbers array
numbers(9) = 100 'assign the number 100 to the last element of the numbers array
names(0) = "Alice" 'assign the string "Alice" to the first element of the names array
names(4) = "Bob" 'assign the string "Bob" to the last element of the names array
colors = "Red", "Green", "Blue" 'assign an array of strings to the colors array
To access values from an array in Visual Basic, you use the name of the array followed by parentheses that specify the index of the value that you want to access. Here are some examples of how to access values from arrays in Visual Basic:
Console.WriteLine(numbers(0)) 'print the first element of the numbers array
Console.WriteLine(numbers(9)) 'print the last element of the numbers array
Console.WriteLine(names(0)) 'print the first element of the names array
Console.WriteLine(names(4)) 'print the last element of the names array
Console.WriteLine(colors(0)) 'print the first element of the colors array
Console.WriteLine(colors(2)) 'print the third element of the colors array
