Question

I have backup folder where I store the images while loading them. So I need to delete the image from the backup folder when deleted from the checked listbox.

So how do I do that?

 If CheckedListBox1.Items.Count = 0 Then
        MsgBox("Please load the images", MsgBoxStyle.Critical)
    Else
        If Thumbcontrol1.SelectedThumbnail Is Nothing Then
            MsgBox("Please select the thumbnail to remove", MsgBoxStyle.Information)
        Else
            CheckedListBox1.Items.Remove(CheckedListBox1.SelectedItem)
            Thumbcontrol1.RemoveSelectedThumbnail()

            If CheckedListBox1.Items.Count > 0 Then
                CheckedListBox1.SelectedIndex = CInt(index)
            End If
            If CheckedListBox1.Items.Count = 0 Then
                Thumbcontrol1.BackgroundImage = My.Resources.backimage
                frmDisplay.GCanvas1.Image = Nothing
            End If
        End If
    End If

You can use the methods in the System.IO.File class to delete a file, by providing the filepath to the method.

System.IO.File.Delete("path\to\file")
