Have you started your Timer? I asked you in one of the multitude of threads in which you've asked this same question whether you had read the documentation for the Timer class. You didn't answer that question but I would assume that the answer is NO.

People here are happy to provide help in different ways. Personally, I'm a big believer in pointing people to where the information can be found and then I expect that if it's important enough to them they will go and read that information. The people who will make good developers are the ones who consider it important enough that they will go and read the information for themselves and try to make use of it, asking questions again if they are unable.
