Public Class frmConnection
Private Sub Button1_Click(ByVal sender As System.Text = ".SqlClient

sw.Load
Dim sr As New StreamReader(".EventArgs) Handles MyBase, ByVal e As System.Close()
Dim mycon As New SqlConnection(str_con)
Try
mycon.txt".Write(TextBox1;, False)
sw.Object.Object.IO
Public Class Form1
