Imports System.Data.SqlClient

    Dim con As New SqlConnection("Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\Database1.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True")


    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

            con.Close()
        End If

        Try
            If RichTextBox1.Text.Length = 0 Then
                MsgBox("MemId field cannot be empty insert value")
            Else
                con.Open()

                Dim instr As String = "INSERT INTO member VALUES('" + RichTextBox1.Text + "','" + RichTextBox2.Text + "','" + RichTextBox3.Text + "','" + RichTextBox4.Text + "','" + RichTextBox5.Text + "','" + RichTextBox6.Text + "')"
                Dim cmd As New SqlCommand(instr, con)
                MsgBox("Database connected successfully")
                Dim rdr = cmd.ExecuteReader()
                If rdr.HasRows Then
                    Label8.Text = "*Record created successfully*"
                    cmd.Dispose()
                End If
                rdr.Close()
                cmd.Dispose()

            End If
        Catch ex As Exception
            MsgBox(ex.Message)
            con.Close()

        End Try

    End Sub

Dim rdr = cmd.ExecuteReader()

I dont think that you can execute an INSERT with ExecuteReader()
There should be another command like cmd.Execute()

For an execute reader, you need a SELECT statement.

Connection string with |DataDirectory| will write any changes at database under the Bin\Debug.
