Answer 1

I'm not sure what controls you specifically talking about here but the parts to retrieve a list of filenames

and to open then files in there appropriate associated application are here.

Create a form with a listbox and a button on it.

Option Strict On
Option Explicit On

Public Class Form1

  Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
    Dim filenames = My.Computer.FileSystem.GetFiles("C:\Windows\Microsoft.NET\Framework\v2.0.50727\en", FileIO.SearchOption.SearchTopLevelOnly, "*.xml")
    ListBox1.Items.AddRange(filenames.ToArray)
  End Sub

 

  Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    Process.Start(ListBox1.SelectedItem.ToString)

  End Sub
End Class

 

This line can be changes to different folder, to recurse to sub folders as well and to change from XML to whatever extension you want ie. pdf

Dim filenames = My.Computer.FileSystem.GetFiles("C:\Windows\Microsoft.NET\Framework\v2.0.50727\en", FileIO.SearchOption.SearchTopLevelOnly, "*.xml")
   

The line

     Process.Start(ListBox1.SelectedItem.ToString)

Will open the selected file from the listbox using the appropriate application for that file type.

 

Answer 2

Hi .

Is there a way only to display the name and not full path. But that is what I wanted.

Thanx.

To get filename only, you can use

System.IO.Path.GetFileName(fullPath)

If don't want extension as well, use this

System.IO.Path.GetFileNameWithoutExtension(FullPath)

To open the PDF file, you can use

Process.Start(fullname)
