Sub ReadTextFile(s As String) // reads the text file in the VirtualVolume Var f, virtualFile As Folderitem Var v As VirtualVolume f = FolderItem.ShowOpenFileDialog("myVirtualVolume") If f <> Nil Then v = f.OpenAsVirtualVolume If v <> Nil Then virtualFile = v.Root.Child(s) If VirtualFile <> Nil Then Var stream As BinaryStream stream = BinaryStream.Open(virtualFile, False) Do TextArea2.AddText(stream.Read(255)) Loop Until stream.EndOfFile stream.Close End If End If End If End Sub
