timer

问题 I have a really basic two-view timer app I'm working on, wherein on View1 I have 30 buttons (15 buttons start timers, 15 of them invalidate each respective timer) and on View2 I have some other functionality not pertinent to my issue. The issue is that my user switches back and forth between these two views while the timers are still running - the timers will still increment as normal when switching between the views but will cease updating their respective labels once they are switched back

问题 I have an application that I need to have wait a specific amount of time, but I also need to be able to cancel the current operation if needed. I have the following code: private void waitTimer(int days) { TimeSpan waitTime = TimeSpan.FromDays(days); System.Timers.Timer timer = new System.Timers.Timer(waitTime.TotalMilliseconds); // Wait for some number of milliseconds timer.Enabled = true; timer.Start(); timer.Elapsed += new ElapsedEventHandler(OnTimedEvent); // Subscribe to event handler

问题 I have a matlab timer object. It is updating a global variable FOO once per second. I have a matlab GUIDE GUI, with a couple of controls, and a single plot frame. The plot frame gets updated by some of the GUI controls, and it gets updated by the timer object. Basically, there are two global variable FOO and BAR. The timer updates FOO, the GUI controls updates BAR. updates to either FOO or BAR need to update the GUI. How to do this? Thanks John 回答1: You can NOT put a watch on a variable.
