Answer 1

The problem is you are using MySqlConnection , and that only must be used with MySql databases. You must use SqlConnection :

Imports System.Data.SqlClient;

Public Class Form1

Dim con As SqlConnection

Private Sub PictureBox1_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PictureBox1.Click
    con = New SqlConnection
    con.ConnectionString = "Data Source=.\SQLEXPRESS;AttachDbFilename=C:\Users\almond\Desktop\TICKETING SYSTEM\TICKETING SYSTEM\Database1.mdf;Integrated Security=True;User Instance=True"
    Try
        con.Open()
        MessageBox.Show("Connected!")
       con.Close()
    Catch ex As SqlException
        MessageBox.Show(ex.Message)
    Finally
        con.Dispose()
    End Try

End Sub
