  3. Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
  4.         Dim connectionString As String
  5.         Dim cnn As OleDbConnection
  6.         connectionString = "Provider=SQLOLEDB;Data Source=KIEVEASNA-PC;Database=dbVitkingHouse;UserID=sa;Password=123"
  7.         cnn = New OleDbConnection(connectionString)
  8.         Try

  10.             MsgBox("Connection Open!")
  11.             cnn.Close()
  12.         Catch ex As Exception
