timer

问题 I create dynamic form with timer(as a reminder) as a notification or alert form. i assign a name on each form. so whenever it is updated.. i want to close or to disable the timer on that certain form so it will never show (as an alert). the for each control to find timer doesn't work, i can't disable it. For Each f As Form In My.Application.OpenForms If (f.Name = Label10.Text) Or (f.Name = "notification" & Label9.Text) Then Dim timer = Me.components.Components.OfType(Of IComponent)().Where

问题 I am trying to run a certain function "foo" every second. I have to do this for a few minutes (say 5). The function foo() makes 100 HTTP Requests (which contains a JSON object) to the server and prints the JSON response. In short, I have to make 100 HTTP requests per second for 5 minutes. I have just started learning python, thus don't have extensive knowledge. This is what I have tried: import threading noOfSecondsPassed = 0 def foo(): global noOfSecondsPassed # piece of code which makes 100

问题 I have a custom control that is used for long time processes. This control has spinning circles around a point. To do this, I am using timer that is working on design time and run-time. When one control is added to form there is no problem. But two of them are added to form, the designer slows down so much. Why does this problem occurs and how can I fix it? My code from this project: public class SpinningCircles : Control { bool fullTransparency = true; int increment = 1; int radius = 4; int

问题 I have two windows forms. I need to open second form in each adjusted time intervals. And second form needs to show up during specified seconds. In mainForm: public static System.Timers.Timer reminderTimer = new System.Timers.Timer(); private static void ActiveteReminder() { int duration = Reminder.Frequency; reminderTimer.Interval = duration; reminderTimer.Elapsed += new System.Timers.ElapsedEventHandler(reminderTimer_Elapsed); reminderTimer.AutoReset = false; reminderTimer.Start(); } static

问题 This question might be a little tricky. I am trying to send a Byte[] over a Windows Socket with a System.Timer. The Data is a wav file, the common encoding is 8Khz 16bits per sample. This article explains in some detail what I am trying to do: Creating audio applications with Bluetooth In an MP3 application, suppose the device is sending an MP3 stream from a file encoded at 128 kbit/sec and 48 kHz sample frequency. This means an MP3 audio frame 384 bytes long is sent every 24.0 msec. So, if

问题 I want to refresh the Kendo UI grid's contents every 60 seconds with up-to-the-minute data. EDIT: Here's how the dataSource is being assigned at initial configuration: parsedData = $.parseJSON(data); var dataSource = new kendo.data.DataSource({ data: parsedData }); $("#grid").kendoGrid({ dataSource: dataSource, . . . Can the grid's dataSource simply be reassigned in one fell swoop? Or would it be better to remove the items in the dataSource.data individually, or by clearing the array, and

问题 I have a Windows service as shown below: Protected Overrides Sub OnStart(ByVal args() As String) Dim timer As System.Timers.Timer = New System.Timers.Timer() timer.Interval = 1000 '1 sec AddHandler timer.Elapsed, AddressOf Me.OnTimer timer.Start() End Sub Private Sub OnTimer(sender As Object, e As Timers.ElapsedEventArgs) Dim Time As String = DateTime.Now.ToString("hh:mm:ss tt") If Time = "01:58:15 PM" Or Time = "02:42:15 PM" Or Time = "02:43:15 PM" _ Or Time = "03:44:15 PM" Or Time = "06:00

问题 Accuracy Vs. Precision What I would like to know is whether I should use System.currentTimeMillis() or System.nanoTime() when updating my object's positions in my game? Their change in movement is directly proportional to the elapsed time since the last call and I want to be as precise as possible. I've read that there are some serious time-resolution issues between different operating systems (namely that Mac / Linux have an almost 1 ms resolution while Windows has a 50ms resolution??). I'm

问题 I have to develop an application that will be required to measure user response time within a series of experiments. This application will be run on approximately 100 computers, thus I had mentioned that a browser based approach might be best to cut down on performing installs and updates. With that said, now that I've read about the accuracy of timers in browsers, specifically javascript timers, I'm learning there can be a delay from a few milliseconds to upwards of 10-15ms. This sort of
