This is achieved using the Visual Basic File System Watcher class.The options available as listed in the following tables: Note that the above code example assumes that the 'C:\Temp' directory already exists. Working with Directories is covered in Working with Directories in Visual Basic. Stream Writer(text File Stream) Dim int Counter As Integer For int Counter = 0 To 10 my File Writer. Stream Reader(text File Stream) Dim int Counter As Integer Dim str File Contents As String For int Counter = 0 To 10 my File Writer. To try this, start Visual Studio and create a new Windows Application project.
