Imports System.Data.SqlClient

Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Dim cn As New SqlConnection("Data Source=C:\Users\Hercules\Documents\Visual Studio 2010\Projects\sln_login\login\login_teste.sdf") 'banco criado no visual studio 2010
Dim cn As New SqlConnection("server=localhost;User Id=root;database=cisotos") 'meu banco mysql

 Dim cmd As New SqlCommand(String.Format("select * from login_cisotos where login = '{0}' and senha = '{1}'", usuarioTextBox.Text, senhaTextBox.Text), cn)
 cmd.CommandType = CommandType.Text
 Try
 cn.Open()
 Dim dr As SqlDataReader = cmd.ExecuteReader()
 If dr.Read() Then
 Me.Close()
 Form2.Show()
 Else
 MessageBox.Show("erro de login", "login error", MessageBoxButtons.OK, MessageBoxIcon.Warning)
 End If
 Catch ex As Exception
 MessageBox.Show(ex.Message, "login error", MessageBoxButtons.OK, MessageBoxIcon.Warning)
 Finally
 If cn.State = ConnectionState.Open Then
 cn.Close()
 End If
 End Try
 End Sub
