Stopwatch - Transfer From Tiemr1 To Timer4 Or To Timer 2
Dec 16, 2011
With a program neovjitet (stopwatch), which can transfer from tiemr1 to timer4 or to timer 2. I want the button to leave this example: 00 Hr 05 min 00 and that starts to count from the back and to tell me how much money this koh must be paid to
And time is:
0min to 24 to 20 eu
24 min to 36 to 30 eu
36 min to 48 to 40 eu
48 min to 60 to 50 eu
Automatically and when to add each 12 min + 10 eu ie when done 01hr: 22min automatically pay out 60 eu.

Is it possible to pause and start the timer (so the current time doesn't get reset when the user clicks the button the second time)?

I am using Timer control as a stopwatch to populate couple of Label controls text field. I am listing the code below which is not updating the Label fields. I have removed the code related to buttons and other controls. Why is the Timer1_Tick not being invoked? The code is compiling clean and when I walked thru the debugger, my Start_Timer() and Stop_Timer() subroutines are working. However, nothing is happening in the Timer1_Tick() subroutine. I would like someone
Dim MyTime As New DateTime

So a timer's maximum interval is 1 which is a thousand ticks a second. A Stopwatch's frequency is 2238906 ticks a second on my pc...
I am wondering if there is a reliable way to trigger an event for each tick of the stopwatch without missing any ticks...
If I can somehow get a Tick event for the stopwatch, I believe I can increase the resolution of my input recorder....

One the click of a button the stopwatch starts, then on the click of a second button the stopwatch stops then states either in a msgbox the time taken between the two button clicks.

I will use the Background Intelligent Transfer Service (BITS) to transfer files from a client (laptop) to a shared folder on a server within our local network.The problem is a very slow network bandwith, if we transfer a file, the other clients canīt work, all requests to other clients (application) or viewing internet pages needs a long time.My idea is to use BITS in my tool to copy/transfer a file from client to server, also I hope to get more performance for the internet requests.

I'm using server.transfer to transfer execution of a URL to a dummy page which fetches information from the database. The trouble is that the master page interacts with the session.
global.asax:

' Fires at the beginning of each request
If Not (System.IO.File.Exists(Server.MapPath(Request.Url.LocalPath))) And Request.Url.LocalPath.ToLower

Master page:
If String.IsNullOrEmpty(CStr(Session("SessionId"))) Then
Session.Add("SessionId", Guid.NewGuid().ToString)
End If

<add name="HttpModuleAggregator" type="XPIdea.Web.HttpModuleAggregator,xpidea.web.common" />
</httpModules>
I'm getting an error :
Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the <configuration><system.web><httpModules> section in the application configuration.
I should also mention that this same master page works elsewhere in the site. Session is used throughout the site as well (not just in the master page).

I have a VB.NET app in which I'd like to use the Stopwatch class. The stopwatch will get reset every time it enters a particular method, which may be in less than a second, or not for hours. Is there a limit to how long you can let a stopwatch run before something bad happens? i.e. an error, or performance degradation?

I have to create a cronometer or stopwatch. I'm not sure how to do this though. I have to have methods for starting it, stoping it, and reseting it. I'm thinking it might need to be a timer, but is this the only way? I have no idea how to work with timers or writing methods for them.

I am writing a very basic memory match card game, and am trying to get the program to flip over the selected cards, wait 2 seconds so the user can see the values, then flip back over. The code I have to do this is:
Private Sub Label_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Label1.Click, Label2.Click, Label3.Click, Label4.Click, Label5.Click, Label6.Click, Label7.Click, Label8.Click, Label9.Click, Label10.Click, Label11.Click, Label12.Click, Label13.Click, Label14.Click, Label15.Click, Label16.Click Dim message As String = "Label Clicked was Index" + sender.TabIndex.ToString

I puzzle with (setting uptime-real time clock) calculation.ex. if I want my stopwatch countdown fromtart: 18.20.30 - stop: 18.50.50 = difference time is 00.30.20 that is easy butstart: 18.20.30- stop: 18.50.40 = difference time is 00.30.40

I designing a stopwatch type OO program and am stuck on trying to figure out the split time function of a stop watch. I want to list the split times in a list box as the user presses the split button and also display the final split time when the user presses the stop button. I feel I'm real close but just can't get over the hump, especially trying to code in OOP. The rest of my program works fine (start, stop, elapsed time). I am programming in VB 2005 and will display my relative code from both the class and form areas.

I have an application that has several stopwatches. I would like to be able to 'sync' a stopwatch with another at any given time. I tried setting the Elapsed time of one stopwatch to that of another stopwatch but I get that that property is 'read only'.

ETA: Using Environment.TickCount does not present the same problem. ETA2: I should add that I don't actually use the Forms.Timer in my app - as this would negate the use of a high frequency timer. I've used it here to simplify the code. ETA3: I've published a workaround as an answer below. I'm having problems with the StopWatch class that I'm observing on a laptop with XP but not a different laptop with Win7. Here's the test code:

I have VS 2008 and wow is it different from the old VB I used about 10 yrs ago! What I am trying to learn is how to create an ap that has a window that displays elapsed time like a stopwatch. Then I would like to be able to click a button to pause that time and start another timer, and then have yet another button to reset all. I have the form designed using a RichTextBox but am not sure that is the best way to display the times.

So I'm getting closer and closer to making the timer work the way I want it to, with one small problem.
I found the following post about returning millisecond and nanosecond: How do you convert Stopwatch ticks to nanoseconds, milliseconds and seconds?
But what I'm trying to do is show only the 10ths of 100ths of a second when desired.
I have the following code:
Private Sub TotalTimer_Tick(sender As System.Object, e As System.EventArgs) Handles TotalTimer.Tick
Dim elapsed As TimeSpan = Me.matchStopwatch.Elapsed

-Timers, but the timer lags too much.
-Stopwatch Class, still lags (little but still).
I need ms accuracy, my prg will replace a hardware stopwatch used in competition.

I need an accurate timer to interface a Windows application to a piece of lab equipment.I used System.Timers.Timer() to create a timer that ticks every 10 msec, but this clock runs slow. For example 1000 ticks with an interval of 10 msec should take 10 wall-clock seconds, but it actually takes more like 20 wall-clock sec (on my PC). I am guessing this is because System.Timers.Timer() is an interval timer that is reset every time it elapses. Since it will always take some time between when the timer elapses and when it is reset (to another 10msec) the clock will run slow. This probably fine if the interval is large (seconds or minutes) but unacceptable for very short intervals.Is there a function on Windows that will trigger a procedure every time the system clock crosses a 10 msec (or whatever) boundary?
UPDATE: System.Timers.Timer() is extremely inaccurate for small intervals.I wrote a simple program that counted 10 seconds several ways:
Interval=1, Count=10000, Run time = 160 sec, msec per interval=16
Interval=10, Count=1000, Run time = 16 sec, msec per interval=15
Interval=100, Count=100, Run time = 11 sec, msec per interval=110
Interval=1000, Count=10, Run time = 10 sec, msec per interval=1000
It seems like System.Timers.Timer() cannot tick faster that about 15 msec, regardless of the interval setting.Note that none of these tests seemed to use any measurable CPU time, so the limit is not the CPU, just a .net limitation (bug?)For now I think I can live with an inaccurate timer that triggers a routine every 15 msec or so and the routine gets an accurate system time. Kinda strange, but...I also found a shareware product ZylTimer.NET that claims to be a much more accurate .net timer (resolution of 1-2 msec). This may be what I need. If there is one product there are likely others.

I have a timer on a page in ASP.NET.
After a certain period of time elapses, I want to disable the timer.
I want to put a static variable in the timers tick event that will track how many seconds have elapsed.
My question is, will this work?
If user X and Y are viewing the page will they both have separate local static variables?
What is the best method of shutting down an ASP.NET timer after a certain elapsed time?

I have a windows application that need to process som quite time consuming jobs. In my first try i did all processing under
the form thread. The result was bad response and update of the form due to the heavy jobs.To get around the problem with bad response from the form i created a new class "processing" where i put all the data processing. Then i instanciated a background worker where i in the "doWork" sub created a new instance of "processing".The "processing" class creates a timer from system.timer, and the timer drives the processing.On the Timer event Elapsed the timer starts a new thread from the thread pool.
My problem is now when i want to asynchronously close the background worker (with the corresponding function call what ever it is called ...) there is still a timer thread out there that causes exceptions for me.
1. How can i close my background worker and at the same time have the timer to be stopped?
2. Is there a way to synchronize the timer event so that the timer executes from the background worker thread?
3. Is there a better approach for me to adapt?

I want to create an array of timer in vb.net. My problem is that how will i raise the tick event for a particular timer, say mytimer(x).tick and inside the tick event there is also a button, say mybutton(x) which changes location every interval. for example:
public class blah
dim mybuttons(20) as button
dim mytimer(20) as timer
private sub form_load(....) handles me.load
for x as integer = 0 to 20
[Code]...
i dont know what to do next, all i want is to pass the button mybuttons(x) to mytimer(x) tick event, in which their index number are the same. i want to create one timer per button. how to do that? please help me and post example codes. i've researched the net but i cant understand passing variables, addhandlers, etc. i'm just new to programming object oriented.
