Timer Only Running Once?

Nov 24, 2010

If a function returns false it is supposed to delete a file and then call the MyTimer.QuickFire event to relaunch the sub. It does this only 1 time, however my problem is that it might return false multiple times before all the function return true. The HourDownload Sub is set to fire every at hour at 5 minutes after the hour, the data could be valid at this time or it might not be valid until 40 to 50 minutes after the hour. So the quickfire event would need to run multiple times until everything returns true and the sub is exited. I also have another Sub Called FiveMinuteDownload that runs every 5 minutes, which is basically identical in structure to the HourDownload Sub. Both of these Subs call the QuickFire event in the event that a function returns false, however both only run once.

Private Sub HourDownload()
DeleteFileHour()
If OneHour() = True Then

If validateOneHourxml() = True Then 'Calls the validateOneHourxml function to see if the xml file is valid or not(if it is valid then it goes onto the next step, if it is not valid then it should call the MyTimer.QuickFire(2) which is a 30 second timer to relauch the HourDownload Sub.)

If HourImport() = True then
DeleteFileHour()
Exit Sub

Create A Timer While The Application Is Running?

May 16, 2012

I want to create a timer while the application is running. For example, the form has TextBox1 and Button1. When Button1 is clicked, the timer will be enabled and will print the current system time in TextBox1 every 10 seconds. The timer will be disabled when the Button1 is clicked again. How do I implement the timer and its events? An example with both Windows Forms and Silverlight would be great.

Running Calculations In A Schedule (not Timer Type)

Jun 9, 2011

I have a bunch of calculations, which will run down for x amount of years or months, specified by the user. These will be in a table (datagridview or something similar), which I will need to access to create reports. So basically calculating the data, then dragging various values at intervals. So it could be any cell at random or patterned. An example of this would be watching how much tax a person paid per year, and how much their income was per year. A pretty basic example. So there would be two columns, and x amount of rows depending on what the user wants to see, in this example, the next 48 months, in months not years. The user then decides to take every 12th value and putting that straight into a report, showing their expected schedule for tax and income.What sort of table structure would be the best to use? The table should be created automatically each time the event (for examples sake a button) is clicked. I'm not sure what I need the event to be based on yet. Most likely the form loading, or when the user tabs onto a new area. Should I use a datagrid view?

I need to filter the database based on selected user input at runtime. I have a Drop Down List, GridView, and button on my webpage. The drop down list is bound to the database, it holds a list of product catagories. The gridview is also linked to the database with a query written so that the displayed data is only that which falls under the selected catagory. I want the query to execute when the button is clicked but i dont know and cant find such a command.

.net - Accurate Windows Timer - System.Timers.Timer() Is Limited To 15 Msec

Jan 15, 2009

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.

Asp.net - Local Static Variables In Timer.Tick Event (Stopping A Timer)

Jul 9, 2009

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?

Synchronize The Timer Event So That The Timer Executes From The Background Worker Thread?

Apr 23, 2009

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?

Create An Array Of Timer - Raise The Tick Event For A Particular Timer?

Jan 11, 2011

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.

.net - Systems.timer.timer Unwanted Multithreading?

Jul 14, 2011

I recently switched my code from using the windows.forms.timer to the systems.timer.timer and it has resulted in a multithreading error. I'm using the timer to trigger just one event so multithreading shouldn't be an issue. To give more detail I have implemented the timer at follows:
At the top of the class I have: Private Shared timr1sec As System.Timers.Timer

When the program loads (Private Sub Test_load):
timr1sec = New System.Timers.Timer(1000)
AddHandler timr1sec.Elapsed, AddressOf OnTimedEvent

In OnTimedEvent I call several subroutines, and write some data to the screen using a ListView object.VisualExpress throws the multithreading error on the last line of this code, which is in OnTimedEvent
