Vb.net Project With Coding Jun 2026

to open the code view. Just below the Public Class Form1 , insert the following class definition:

Private Sub btnAdd_Click(sender As Object, e As EventArgs) Handles btnAdd.Click Using conn As New SqlConnection(connectionString) conn.Open() Dim query As String = "INSERT INTO Students (Name, Age, Course) VALUES (@Name, @Age, @Course)" Using cmd As New SqlCommand(query, conn) cmd.Parameters.AddWithValue("@Name", txtName.Text) cmd.Parameters.AddWithValue("@Age", Integer.Parse(txtAge.Text)) cmd.Parameters.AddWithValue("@Course", txtCourse.Text) cmd.ExecuteNonQuery() End Using End Using LoadStudents() ClearFields() End Sub Vb.net Project With Coding

CREATE TABLE Students ( StudentID INT PRIMARY KEY IDENTITY(1,1), Name NVARCHAR(100) NOT NULL, Age INT NOT NULL, Course NVARCHAR(100) NOT NULL ); GO to open the code view

Using conn As SqlConnection = GetConnection() Using cmd As New SqlCommand(query, conn) cmd.Parameters.AddWithValue("@Search", searchValue) Using adapter As New SqlDataAdapter(cmd) adapter.Fill(dataTable) End Using End Using End Using Course) VALUES (@Name

USE StudentDB; GO

For those ready to move beyond forms and databases, let's build a file encryptor using the (AES) algorithm. This project will impress potential employers.
