In addition to Jess'es suggestions, a Timer can be used to postpone a certain action. For instance: when the user moves through a List or Grid, the details (perhaps in TextBoxes) should be updated). Since this updating might be slow, the action is postponed until the user stays on a certain record for, say, a second. This sounds difficult, but is fairly easy to achieve with a timer:

Each time the user moves to a different record, the Timer is enabled (.Enabled = .T.) and reset (.Reset()). If the user moves to another record in less than a second, the Timer is Reset again, therefore, it doesn't fire yet. If the user stops, the Timer is allowed to run.

When the Timer runs, it first disables itself (This.Enabled = .F.), then does the necessary refresh work, which is either programmed directly into the Timer() Event, or the Timer() Event calls a form method.

I use a Timer mostly to postpone deletion of files: I create a temporary file which has to be opened by an external program (for instance, NotePad). Since I don't want to delete the file before NotePad has the chance to open it, I postpone the deletion for a few minutes.
