问题 I'm making an application and I'm using a timer in that application to change label content in WPF C# .NET. In the timer's elapsed event I'm writing the following code lblTimer.Content = "hello"; but its throwing an InvalidOperationException and gives a message The calling thread cannot access this object because a different thread owns it. I'm using .NET framework 3.5 and WPF with C#. Please help me. Thanks in advance. 回答1: For .NET 4.0 it is much simpler to use a DispatcherTimer. The

问题 I'm currently trying to have a function called every 10ms to acquire data from a sensor. Basically I was trigerring the callback from a gpio interupt but I changed my sensor and the one I'm currently using doesn't have a INT pin to drive the callback. So my goal is to have the same behaviour but with an internal interupt generated by a timer. I tried this from this topic import threading def work (): threading.Timer(0.25, work).start () print(time.time()) print "stackoverflow" work () But

问题 In the following Playground example, the UI updates with the current date correctly, however when navigating away from the page and coming back the timer does not resume ticking: import SwiftUI import PlaygroundSupport struct MainTabView: View { let timer = Timer.publish(every: 1, on: .main, in: .common) @State var time = Date() var body: some View { TabView { VStack { Text("\(time)").onReceive(self.timer) { self.time = $0 } } .onAppear { _ = self.timer.connect() } .tabItem { Text("Page 1") }

问题 I have a code which shows me the current date and time when I run my application DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss"); Calendar cal = Calendar.getInstance(); System.out.println(dateFormat.format(cal.getTime())); Now it shows me: 2012/12/11 00:36:53 when I run it. But I want it to count the time during running it. So by example now when I run it on 00:37:53 it shows this time, but I want 00:37:53 at starting and I stop running it on 00:40:55 . I want that it

问题 In my Azure Functions I have 26 functions and only 7 with the timer trigger (see my previous post also I saw this other post but it is quite old). There is no recommendation for Microsoft about it. Some functions have a timer trigger and at the end of the process each function sends an email. I have 2 type of timer trigger: run a function every 20 minutes run a function once at a particular time in the night Every 20 minutes the function is doing what I expect The problem I'm facing is with

问题 Here is my goal: To make a small program (text based) that will start with a greeting, print out a timer for how long it has been since the last event, and then a timer for the event. I have used this code to start out with trying to figure out a timer, but my first problem is that the timer keeps repeating on a new line with each new second. How do I get that to stop? Also, this timer seems to lag behind actual seconds on the clock. import os import time s=0 m=0 while s<=60: os.system('cls')

问题 This question already has answers here : Convert int (number) to string with leading zeros? (4 digits) [duplicate] (4 answers) Closed 6 days ago . I created a timer that returns the decreasing time: public static void timerIdle_Tick(object sender, EventArgs e) { if (tempo >= 60) { minuto = tempo / 60; segundo = tempo % 60; } else { minuto = 0; segundo = tempo; } segundo--; if (minuto > 0) { if (segundo < 0) { segundo = 59; minuto--; } } if (minuto == 0 && segundo == 0) { timerIdle.Stop();
