This timer is optimized for use in Windows Forms applications and must be used in a window.
The following example implements a simple interval timer, which sets off an alarm every five seconds. When the alarm occurs, a MessageBox displays a count of the number of times the alarm has started and prompts the user as to whether the timer should continue to run. A Timer is used to raise an event at user-defined intervals. This Windows timer is designed for a single-threaded environment where UI threads are used to perform processing.
It requires that the user code have a UI message pump available and always operate from the same thread, or marshal the call onto another thread. When you use this timer, use the Tick event to perform a polling operation or to display a splash screen for a specified period of time.
Whenever the Enabled property is set to true and the Interval property is greater than zero, the Tick event is raised at intervals based on the Interval property setting. The Windows Forms Timer component is single-threaded, and is limited to an accuracy of 55 milliseconds. If you require a multithreaded timer with greater accuracy, use the Timer class in the System.
