timer

问题 After the long time I spent getting an analog clock to work, I am trying to make a digital one ( sigh ). I am trying to do this with 10 PNGs with the numbers 0 - 9. Each digit of the clock would be an image. The only problem with this is retrieving the certain digit from the current time. I've tried converting the time to a string and using the characterAtIndex, but that doesn't seem to work. What would be the best way to get around this? 回答1: You could use NSDateComponents and NSCalendar :

问题 i ve used some ex from stackoverflow but sometimes my timer fire twice: this clock should fire each one minute, but just assume that it fires 00:00:59.666 then step1 = 59; step2 = 59; step3 = 1; return (1000-666); so it should fire not next minute but next 333 mili second, what can i do? public int SyncTime = 60; Clock = new System.Timers.Timer {AutoReset = false}; Clock.Elapsed += DoJob; Clock.Interval = GetSync(SyncTime); Clock.Start() private void DoJob(object sender, ElapsedEventArgs

问题 I have an asp.net application that is supposed to act like a stopwatch timer. I've tried variations on how to get the timer to count time using seconds. I used an algorithm that was largely inefficient. I then tried using timespan objects using datetime math, but since this basically made a clock it was undesireable. Now I'm trying to implement System.Diagnostics so I can use a Stopwatch object. When I run my program, the label that is supposed to update with the time just displays all 0's.

问题 I'm making simple game where I need to remove pictures after certain time without freezing everything else. I'm making explode event: private void Explode(int x, int y) { PictureBox explosion = new PictureBox(); explosion.Image = Properties.Resources.explosion; explosion.SizeMode = PictureBoxSizeMode.StretchImage; explosion.Size = new Size(50, 50); explosion.Tag = "explosion"; explosion.Left = x; explosion.Top = y; this.Controls.Add(explosion); explosion.BringToFront(); } I have already one

问题 I am making an application using VB6 in which a WebBrowser window is launched using this code: Private Sub Form_Load() WebBrowser1.Navigate ("http://google.com") End Sub How can I make the window refresh the same url every let's say 3 minutes ? I know it should be something well known but i am still searching my way through VB programming 回答1: You don't need 2 timers. just have a global variable globalTimer As Date that keeps the last time you navigated You can set Timer1 to run every second

问题 I have a timer setup like so: var timerID; $this.hover(function(){ $this.find('.stage_obj').each(function(index){ var current_obj = $(this); timerID = setTimeout(function(){ animate_on_top(current_obj, index);}, parseInt(OS.delay_y_on_set[index],10)); }); }, function(){ clearTimeout(timerID); }); There are functions to control the animation in/out on hover. The timers are acting as delays (.delay won't work in my situation). Everything works fine, except the timer isn't cancelled on mouse
