3. VBA Fundamentals: Key Concepts

3.1. Modules and Procedures

3.1.1. Modules

A module is a container for VBA code. It can be a standard module, a class module, or a form module. To insert a module:

Open the VBE: Access the Visual Basic Editor.
Insert Module: In the VBE, go to Insert > Module.
Code Window: A new module will appear in the Project Explorer, and a code window will open where you can write your VBA code.

3.1.2. Procedures

Procedures are blocks of VBA code that perform specific tasks. There are two main types of procedures:

Sub Procedures: Execute a series of statements but do not return a value.

Sub MySubProcedure()
    ' Code to perform a specific task
    MsgBox "Hello from MySubProcedure!"
End Sub

Function Procedures: Execute a series of statements and return a value.

Function MyFunction(ByVal num As Integer) As Integer
    ' Code to perform a calculation and return a value
    MyFunction = num * 2
End Function

3.2. Variables and Data Types

Variables are used to store data values that can change during the execution of your code. Before using a variable, you need to declare it and specify its data type. Common data types include:

Integer: Stores whole numbers (e.g., Dim age As Integer).
Long: Stores larger whole numbers (e.g., Dim population As Long).
Single: Stores single-precision floating-point numbers (e.g., Dim price As Single).
Double: Stores double-precision floating-point numbers (e.g., Dim pi As Double).
String: Stores text (e.g., Dim name As String).
Boolean: Stores True or False values (e.g., Dim isDone As Boolean).
Date: Stores date and time values (e.g., Dim today As Date).
Variant: Can store any type of data (e.g., Dim anything As Variant).

Here’s an example of declaring and using variables:

Sub VariableExample()
    Dim name As String
    Dim age As Integer

    name = "John Doe"
    age = 30

    MsgBox "Name: " & name & vbCrLf & "Age: " & age
End Sub

3.3. Operators

Operators are symbols used to perform operations on variables and values. Common operators include:

Arithmetic Operators: + (addition), - (subtraction), * (multiplication), / (division), ^ (exponentiation), Mod (modulus).
Comparison Operators: = (equal to), <> (not equal to), < (less than), > (greater than), <= (less than or equal to), >= (greater than or equal to).
Logical Operators: And (logical AND), Or (logical OR), Not (logical NOT).
Concatenation Operator: & (used to concatenate strings).

Here’s an example of using operators:

Sub OperatorExample()
    Dim num1 As Integer
    Dim num2 As Integer
    Dim sum As Integer
    Dim product As Integer

    num1 = 10
    num2 = 5

    sum = num1 + num2
    product = num1 * num2

    MsgBox "Sum: " & sum & vbCrLf & "Product: " & product
End Sub

3.4. Control Structures

Control structures allow you to control the flow of your code based on certain conditions. Key control structures include:

If…Then…Else: Executes different blocks of code based on a condition.

Sub IfThenElseExample()
    Dim num As Integer
    num = 10

    If num > 5 Then
        MsgBox "Number is greater than 5"
    Else
        MsgBox "Number is not greater than 5"
    End If
End Sub

Select Case: Executes different blocks of code based on multiple conditions.

Sub SelectCaseExample()
    Dim day As String
    day = "Monday"

    Select Case day
        Case "Monday"
            MsgBox "It's Monday!"
        Case "Tuesday"
            MsgBox "It's Tuesday!"
        Case Else
            MsgBox "It's another day!"
    End Select
End Sub

For…Next Loops: Repeats a block of code a specific number of times.

Sub ForNextExample()
    Dim i As Integer

    For i = 1 To 5
        MsgBox "Iteration: " & i
    Next i
End Sub

Do…While Loops: Repeats a block of code as long as a condition is true.

Sub DoWhileExample()
    Dim num As Integer
    num = 1

    Do While num <= 5
        MsgBox "Number: " & num
        num = num + 1
    Loop
End Sub

3.5. Working with Objects

3.5.1. Object Model

The object model is a hierarchical structure that represents the objects available in an Office application. Understanding the object model is crucial for manipulating objects using VBA.

Application Object: Represents the Office application itself (e.g., Excel, Word).
Workbook Object: Represents an Excel workbook.
Worksheet Object: Represents a worksheet in an Excel workbook.
Range Object: Represents a range of cells in a worksheet.
Document Object: Represents a Word document.
Paragraph Object: Represents a paragraph in a Word document.
Slide Object: Represents a slide in a PowerPoint presentation.
MailItem Object: Represents an email in Outlook.

3.5.2. Object Properties and Methods

Objects have properties that define their characteristics and methods that perform actions.

Properties: Attributes that describe the object (e.g., Range.Value, Range.Font.Bold).
Methods: Actions that the object can perform (e.g., Range.Select, Workbook.Save).

Here’s an example of working with objects in Excel:

Sub ObjectExample()
    ' Declare variables
    Dim wb As Workbook
    Dim ws As Worksheet
    Dim rng As Range

    ' Set object variables
    Set wb = ThisWorkbook ' Represents the current workbook
    Set ws = wb.Sheets("Sheet1") ' Represents "Sheet1"
    Set rng = ws.Range("A1:C3") ' Represents cells A1 to C3

    ' Set properties
    rng.Value = "Hello VBA!"
    rng.Font.Bold = True

    ' Perform a method
    rng.Select

    ' Clear object variables
    Set wb = Nothing
    Set ws = Nothing
    Set rng = Nothing
End Sub

3.6. Events

Events are actions or occurrences that VBA can respond to. Events are specific to each application. They can include:

Workbook Events (Excel): triggered when a workbook is opened, closed, or saved.
Worksheet Events (Excel): triggered when a worksheet is activated, changed, or calculated.
Document Events (Word): triggered when a document is opened, closed, or saved.
Application Events (Outlook): triggered when an email is received or sent.

To write an event handler:

Open the VBE: Access the Visual Basic Editor.
Select the Object: In the Project Explorer, select the object for which you want to handle an event (e.g., a worksheet or workbook).
Select the Event: In the code window, select the object from the left dropdown and the event from the right dropdown.
Write the Code: VBA will automatically generate the event handler, and you can write the code to respond to the event.

Here’s an example of an event handler in Excel:

Private Sub Workbook_Open()
    MsgBox "Workbook opened!"
End Sub

    ' Check if the input is a number
    If Not IsNumeric(num) Then
        Err.Raise 13, "ErrorHandlingExample", "Invalid input: Please enter a number."
    End If

    ' Code that might cause an error
    Dim result As Integer
    result = 100 / num

    MsgBox "Result: " & result

    Exit Sub ' Exit the procedure to avoid running the error handler if no error occurred

ErrorHandler:
    MsgBox "Error: " & Err.Description, vbCritical, Err.Source
End Sub

5.3. Code Optimization

Optimizing your code can improve its performance and efficiency. Consider the following tips:

Declare Variables: Always declare variables with specific data types.

Disable Screen Updating: Turn off screen updating to speed up code execution.

Application.ScreenUpdating = False
' Your code here
Application.ScreenUpdating = True

In VBA, you can use APIs to extend the capabilities of Office applications by interacting with external systems and services.

6.1.2. Declaring APIs in VBA

To use an API in VBA, you must declare it using the Declare statement. The Declare statement specifies the name, library, and arguments of the API function.

Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" ( _
    ByVal hWnd As Long, _
    ByVal lpOperation As String, _
    ByVal lpFile As String, _
    ByVal lpParameters As String, _
    ByVal lpDirectory As String, _
    ByVal nShowCmd As Long _
) As Long

6.1.3. Example: Opening a Website Using ShellExecute API

Sub OpenWebsite()
    Dim retVal As Long
    retVal = ShellExecute(0, "open", "https://www.LEARNS.EDU.VN", vbNullString, vbNullString, vbNormalFocus)
    If retVal <= 32 Then
        MsgBox "Failed to open website. Error code: " & retVal
    End If
End Sub

6.1.4. Common APIs

Some common APIs used in VBA include:

ShellExecute: Opens files or websites.
CreateProcess: Starts a new process.
GetTickCount: Retrieves the number of milliseconds that have elapsed since the system started.
GetUserName: Retrieves the name of the current user.

6.2. Working with External Databases

6.2.1. Connecting to Databases

VBA allows you to connect to external databases such as Microsoft Access, SQL Server, Oracle, and MySQL using ActiveX Data Objects (ADO). To connect to a database, you need to create a connection object and specify the connection string.

Sub ConnectToDatabase()
    Dim cn As ADODB.Connection
    Dim rs As ADODB.Recordset
    Dim strConnection As String
    Dim strSQL As String

    ' Create a connection object
    Set cn = New ADODB.Connection

    ' Specify the connection string
    strConnection = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:DatabaseMyDatabase.accdb;"

    ' Open the connection
    cn.Open strConnection

    ' Create a recordset object
    Set rs = New ADODB.Recordset

    ' Specify the SQL query
    strSQL = "SELECT * FROM Employees;"

    ' Open the recordset
    rs.Open strSQL, cn

    ' Check if there are any records
    If Not rs.EOF Then
        ' Loop through the records
        Do While Not rs.EOF
            Debug.Print rs.Fields("EmployeeID").Value & " - " & rs.Fields("FirstName").Value & " " & rs.Fields("LastName").Value
            rs.MoveNext
        Loop
    Else
        Debug.Print "No records found."
    End If

    ' Close the recordset and connection
    rs.Close
    cn.Close

    ' Clean up
    Set rs = Nothing
    Set cn = Nothing
End Sub

6.2.2. Common Database Operations

Some common database operations you can perform using VBA include:

Selecting Data: Retrieves data from a database using SQL queries.
Inserting Data: Adds new records to a database.
Updating Data: Modifies existing records in a database.
Deleting Data: Removes records from a database.

6.3. Working with Arrays

6.3.1. Understanding Arrays

Arrays are used to store multiple values of the same data type in a single variable. Arrays can be one-dimensional or multi-dimensional.

6.3.2. Declaring Arrays

To declare an array in VBA, you need to specify the data type and the number of elements.

Sub ArrayExample()
    Dim numbers(1 To 5) As Integer ' Declare an array of 5 integers
    Dim names(1 To 3) As String ' Declare an array of 3 strings

    ' Assign values to the array
    numbers(1) = 10
    numbers(2) = 20
    numbers(3) = 30
    numbers(4) = 40
    numbers(5) = 50

    names(1) = "John"
    names(2) = "Jane"
    names(3) = "Mike"

    ' Loop through the array and print the values
    Dim i As Integer
    For i = 1 To 5
        Debug.Print "Number(" & i & ") = " & numbers(i)
    Next i

    For i = 1 To 3
        Debug.Print "Name(" & i & ") = " & names(i)
    Next i
End Sub

6.3.3. Dynamic Arrays

Dynamic arrays can be resized at runtime. To declare a dynamic array, you do not specify the number of elements initially.

Sub DynamicArrayExample()
    Dim numbers() As Integer ' Declare a dynamic array

    ' Resize the array
    ReDim numbers(1 To 5)

    ' Assign values to the array
    numbers(1) = 10
    numbers(2) = 20
    numbers(3) = 30
    numbers(4) = 40
    numbers(5) = 50

    ' Loop through the array and print the values
    Dim i As Integer
    For i = 1 To 5
        Debug.Print "Number(" & i & ") = " & numbers(i)
    Next i
End Sub

6.3.4. Multidimensional Arrays

Multidimensional arrays have more than one dimension. For example, a two-dimensional array can be used to store data in a table format.

Sub MultidimensionalArrayExample()
    Dim data(1 To 3, 1 To 2) As String ' Declare a 2D array

    ' Assign values to the array
    data(1, 1) = "John"
    data(1, 2) = "Doe"
    data(2, 1) = "Jane"
    data(2, 2) = "Smith"
    data(3, 1) = "Mike"
    data(3, 2) = "Johnson"

    ' Loop through the array and print the values
    Dim i As Integer, j As Integer
    For i = 1 To 3
        For j = 1 To 2
            Debug.Print "Data(" & i & ", " & j & ") = " & data(i, j)
        Next j
    Next i
End Sub

6.4. Working with Classes

6.4.1. Understanding Classes

A class is a template for creating objects. Classes define the properties and methods that objects of that class will have.

6.4.2. Creating Class Modules

To create a class module in VBA:

Open the VBE: Access the Visual Basic Editor.
Insert Class Module: In the VBE, go to Insert > Class Module.
Code Window: A new class module will appear in the Project Explorer, and a code window will open where you can define the properties and methods of the class.

6.4.3. Defining Properties and Methods

' Class Module: clsPerson
Private pFirstName As String
Private pLastName As String

' Property Let for FirstName
Public Property Let FirstName(ByVal value As String)
    pFirstName = value
End Property

' Property Get for FirstName
Public Property Get FirstName() As String
    FirstName = pFirstName
End Property

' Property Let for LastName
Public Property Let LastName(ByVal value As String)
    pLastName = value
End Property

' Property Get for LastName
Public Property Get LastName() As String
    LastName = pLastName
End Property

' Method to get full name
Public Function GetFullName() As String
    GetFullName = pFirstName & " " & pLastName
End Function

6.4.4. Using Classes

Sub UseClassExample()
    Dim person As clsPerson

    ' Create an instance of the class
    Set person = New clsPerson

    ' Set the properties
    person.FirstName = "John"
    person.LastName = "Doe"

    ' Call the method
    Debug.Print "Full Name: " & person.GetFullName()

    ' Clean up
    Set person = Nothing
End Sub
