problem with my login form

[badrat]

hi guys, i've created a form with 2 text box(UserName, UserPassword) and 1 button(LOGIN), I've added my data source from my database. I seem to have a problem with validating with my database where i've inserted my users and password there. Can anyone help me?

Dim Conn As New SqlClient.SqlConnection("Data Source=DATA;Initial Catalog=MyDatabase1;Integrated Security=TruData Source=DATA;Initial Catalog=MyDatabase1;Integrated Security=True")
Dim myCommand As String = "Select * From Users Where UserName=username AND Userpassword=userpassword"
Dim mysqlcommand As New SqlClient.SqlCommand(myCommand, Conn)
Dim mySqlReader As SqlClient.SqlDataReader

mysqlcommand.Parameters.Add(New SqlClient.SqlParameter("Username", SqlDbType.VarChar))
mysqlcommand.Parameters("Username").Value = UsernameTextBox.Text

mysqlcommand.Parameters.Add(New SqlClient.SqlParameter("userpassword", SqlDbType.VarChar))
mysqlcommand.Parameters("userpassword").Value = passwordtextbox.Text

Conn.Open()
mySqlReader = mysqlcommand.ExecuteReader

If mySqlReader.HasRows Then
Me.Hide()
Options.Show()
Else
Me.Hide()
ErrorMessage.Show()
End If

Conn.Close()
