Opening a file from List View? - vb.net

Question

This is my first question on the site and I am fairy new at how code works. I need to be able to open a file from a list view. I can get the file path to open up my file explorer, but can not get it to directly open the selected file. It gives me an error saying "System.ComponentModel.Win32Exception: 'The system cannot find the file specified" I've checked the file path from my file explorer and the path it pulls from and they both seem to match. Here is an example of what I've written.
Private Sub ListView1_Function(sender As Object, e As EventArgs) Handles ListView1.ItemSelectionChanged
If Not ListView1.SelectedItems.Item(0).Text = "" Then
For Each ListViewItemVar As ListViewItem In ListView1.Items
Dim filePath As String = $"C:\Users\{My.User.Name.Split("\").ElementAt(1)}\S & J Tube Inc\Files_Storage - Documents\Shipping Wizard\"
Dim selectedFile As String = ListViewItemVar.Text
If ListViewItemVar.Selected = True Then
If MessageBox.Show("You are about to open " & filePath & ". Are you sure?", "Open File", MessageBoxButtons.YesNo, MessageBoxIcon.Information) = DialogResult.Yes Then
Process.Start(filePath + selectedFile)
ElseIf DialogResult.No Then
MsgBox("You decided not to open the file.")
End If
End If
Next
End If
End Sub

You have to use ListView1_ItemActivate
1.Create a project with Form with ListView1 and Label1 controls on it
2.Replace yourName in dirInfo with your name from Users\eee\Documents
And all the code you need is :
Imports System.IO
Public Class Form1
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
'CreateHeadersAndFillListView
ListView1.View = View.Details
ListView1.Columns.Add("Filename")
ListView1.Columns.Add("Size")
ListView1.Columns.Add("Last accessed")
Dim dirInfo As New DirectoryInfo("C:\Users\yourName\Documents")
Dim fileInfo As FileInfo
Dim lvi As ListViewItem
Dim lvsi As ListViewItem.ListViewSubItem
For Each fileInfo In dirInfo.GetFiles("*.*")
lvi = New ListViewItem With {
.Text = fileInfo.Name,
.ImageIndex = 1,
.Tag = fileInfo.FullName
}
lvsi = New ListViewItem.ListViewSubItem With {
.Text = fileInfo.Length.ToString()
}
lvi.SubItems.Add(lvsi)
lvsi = New ListViewItem.ListViewSubItem With {
.Text = fileInfo.LastAccessTime.ToString()
}
lvi.SubItems.Add(lvsi)
ListView1.Items.Add(lvi)
Next
'after populating the list this will size columns to the width of column data
ListView1.AutoResizeColumns(ColumnHeaderAutoResizeStyle.ColumnContent)
Label1.Text = "C:\Users\yourName\Documents" + Environment.NewLine + " (Double click to open file !)"
AddHandler ListView1.ItemActivate, AddressOf ListView1_ItemActivate
End Sub
Private Sub ListView1_ItemActivate(sender As Object, e As System.EventArgs)
Dim filename As String = ListView1.SelectedItems(0).Tag.ToString()
Try
Process.Start(filename)
Catch
Return
End Try
End Sub
