Developing a Sample Visual Basic Project: A Simple Student Management System

To illustrate how to prepare a project report with source code, let’s consider a straightforward Student Management System built in Visual Basic. This application allows users to add, view, update, and delete student records stored in an Access database.

System Requirements and Environment

• Visual Basic 6.0 or Visual Basic .NET (version depending on preference)
• Microsoft Access database (.mdb or .accdb)
• Operating System: Windows XP/7/10
• Development Environment: Visual Studio or VB IDE

Design and Implementation Details

Database Design

The database table “Students” contains:

• StudentID (Primary Key)
• Name
• Age
• Gender
• Course

UI Components

• Textboxes for input fields
• ListView or DataGridView for displaying records
• Buttons for Add, Update, Delete, and Clear operations

Core Source Code Explanation

Below is a simplified version of the source code snippets with explanations:

```vb

' Establish database connection

Dim conn As New ADODB.Connection

Dim rs As New ADODB.Recordset

Private Sub Form_Load()

' Open connection to Access database

conn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=students.mdb;"

conn.Open

LoadData()

End Sub

' Load data into ListView

Private Sub LoadData()

ListViewStudents.ListItems.Clear

rs.Open "SELECT FROM Students", conn, adOpenStatic, adLockOptimistic

Do While Not rs.EOF

Dim item As ListItem

Set item = ListViewStudents.ListItems.Add(, , rs("StudentID"))

item.SubItems(1) = rs("Name")

item.SubItems(2) = rs("Age")

item.SubItems(3) = rs("Gender")

item.SubItems(4) = rs("Course")

rs.MoveNext

Loop

rs.Close

End Sub

```

This code initializes the database connection, loads existing student records into a ListView, and prepares the system for CRUD operations.

Adding a New Student Record

```vb

Private Sub btnAdd_Click()

Dim sql As String

sql = "INSERT INTO Students (Name, Age, Gender, Course) VALUES ('" & txtName.Text & "', " & txtAge.Text & ", '" & cboGender.Text & "', '" & txtCourse.Text & "')"

conn.Execute sql

LoadData

MsgBox "Record added successfully!"

End Sub

```

This snippet captures data from input controls and inserts a new record into the database.

Updating a Record

```vb

Private Sub btnUpdate_Click()

Dim sql As String

sql = "UPDATE Students SET Name='" & txtName.Text & "', Age=" & txtAge.Text & ", Gender='" & cboGender.Text & "', Course='" & txtCourse.Text & "' WHERE StudentID=" & lblID.Caption

conn.Execute sql

LoadData

MsgBox "Record updated successfully!"

End Sub

```

Deleting a Record

```vb

Private Sub btnDelete_Click()

Dim sql As String

sql = "DELETE FROM Students WHERE StudentID=" & lblID.Caption

conn.Execute sql

LoadData

MsgBox "Record deleted successfully!"

End Sub

```

Best Practices in Writing the Project Report
