Bonjour;
Je veux créer un logiciel qui ouvre mes documents et les lires dans une fenetre ( documents|*. Txt;* .Rtf ;* . Docs ;* . PDF ;* . Xlsx )
Avec PictureBox rien ne marche j’ai une croix rouge à la place.

Imports System.Net
Public Class Form4
 
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
