Code
Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click If System.IO.File.Exists(TextBox1.Text) = True Then Dim objreader As New System.IO.StreamReader(TextBox1.Text) TextBox2.Text = objreader.ReadToEnd objreader.Close() Else MessageBox.Show("That file does not exist!") End If End Sub Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click TextBox2.Clear() End Sub End Class
