To connect a VB.NET Windows Forms application to a MySQL database (created/viewed using MySQL Workbench), follow these steps: 1. Install MySQL Connector/NET Download and install MySQL Connector/NET, or add the NuGet package: Install-Package MySql.Data 2. Import the MySQL Namespace Imports MySql.Data.MySqlClient 3. Create a Connection String Dim connStr As String = "Server=localhost;Database=mydatabase;Uid=root;Pwd=password;" Replace: localhost ? MySQL server name/IP mydatabase ? Your database name root ? MySQL username password ? MySQL password 4. Test the Connection Imports MySql.Data.MySqlClient Public Class Form1 Private Sub btnConnect_Click(sender As Object, e As EventArgs) Handles btnConnect.Click Dim connStr As String = "Server=localhost;Database=mydatabase;Uid=root;Pwd=password;" Using conn As New MySqlConnection(connStr) Try conn.Open() MessageBox.Show("Connected Successfully!") Catch ex As Exception MessageBox.Show("Connection Failed: " & ex.Message) End Try End Using End Sub End Class 5. Retrieve Data from MySQL Dim query As String = "SELECT * FROM tbl_asset_warranty" Using conn As New MySqlConnection(connStr) conn.Open() Dim cmd As New MySqlCommand(query, conn) Dim reader As MySqlDataReader = cmd.ExecuteReader() While reader.Read() MessageBox.Show(reader("asset_id").ToString()) End While End Using 6. Display Data in a DataGridView Dim query As String = "SELECT * FROM tbl_asset_warranty" Using conn As New MySqlConnection(connStr) Dim da As New MySqlDataAdapter(query, conn) Dim dt As New DataTable() da.Fill(dt) DataGridView1.DataSource = dt End Using

Connecting a VB.NET Windows Forms application to MySQL is not difficult once you install the right connector. First, install MySQL Connector/NET from MySQL Official Website (fun games free). After that, open your Windows Forms project in Visual Studio and add a reference to MySql.Data.dll . Next, create a connection string that matches your MySQL Workbench server settings. Example: Imports MySql.Data.MySqlClient Public Class Form1 Dim conn As New MySqlConnection( "server=localhost;userid=root;password=yourpassword;database=testdb") Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click Try conn.Open() MessageBox.Show("Connected to MySQL successfully!") conn.Close() Catch ex As Exception MessageBox.Show(ex.Message) End Try End Sub End Class In this example, localhost is the MySQL server, root is the username, and testdb is the database name created in MySQL Workbench. When you run the application and click the button, the program will attempt to connect to MySQL and display a success message if everything is configured correctly.
