View 5 RepliesPausing A Process In Midstream Using Timer?
Sep 23, 2011I have a VB Windows App created using VS2K10. It produces pdf files from SQL data. The SQL data is refreshed every 10 minutes pulling from a DB2 (ERP) system via a Linked Server by a SQL DTS package being run by SQL Job Agent (SQL 2005). Because of OLEDB and security issues, the data download can only be performed by a specific Windows 2003 server. (It takes from 2-3.5 minutes to download the necessary data.)
Now, if the process of creating and printing the PDF files takes longer than 6 minutes then it's still running while the next data download is starting, the result of which is that several PDF files are created blank or absent any data. I tried to execute the DTS package on demand instead of on a timer, but cannot get past the OLEDB quirks related to our iSeries (IBM server) DB2 database system. The only answer seems to be to have the client application pause at a specific time interval and resume after @ 4 minutes, but I haven't a clue as to how to do that. Before you ask, using ODBC to pull specific data from the DB2 system directly into the client is too slow to be a viable option.
Timer - .net Console App Pausing And Staying Open?
Mar 20, 2012i am trying to understand how to keep my console app open even after it gathers data and sends it off. I am converting a GUI to the console app. It has a timer that fires the sub every 20 seconds. But it doesnt seem like it works in the console app since after it fires off the sub it closes the app without waiting.

Threading Pausing Not Using Sleep
May 20, 2009I know there is always better ways of doing things. Normally when you create a thread and I want it to pause/sleep for a set amount of time I use the <Object>.Sleep(1000) but this is frowned upon in .Net2+.

VS 2010 Pausing Execution In VB?
Oct 21, 2010okay this may be a simple answer so I apologize if it is. What I'm trying to do is when button1 is clicked for a text box to display text. Then when that same button is clicked again, that text box will display different text. Then so fourth for about another 4 times. Now I know putting this all together will create one big execution, which I don't want. I just want the application to wait until the button is clicked again to display different text.
View 8 RepliesPausing An Application Until A Sub Routine Is Reached?
Apr 16, 2010I have a problem with my application "getting ahead of itself" what the problem stems from is i am manipulating a file and then using the manipulated file further along in the program, the trouble is the program is getting to the second step before the file manipulation is complete so i receive a file not found exception. The program that is doing the manipulation has an OnEnd sub routine and i have been looking at event handlers to try and figure out how i can hold up the application until the On End routine is fired. But i have been trying this to no avail, is there an example i can have that waits for an event to be fired?

Pausing An Application Until A File With A Certain Extension Has Been Created?
Oct 21, 2009I would like some information on pausing my application until a file with a certain extension has been created. What hapens is, my application creates an input file that is sent to an external app that returns a file with a different file extension. In my application i then extract data from this new file.I was thinking i could use a timer to "hold up" my app, but then i started reading about event handlers and catchers. What i have tried is using an If FileExists loop but i get a file not found exception. How should i use the file create event? By looking in the folder and "waiting" for the file to be created?

View 1 RepliesStop Pausing When I Scroll Or Move Windows?
Jun 7, 2011I'm making... well, it's sort of like a game in VB.net (using VS2008, if it matters). Being sort of like a game, it's dependent on timing, but it also has a large area (have to scroll the window on pretty much any resolution).The problem I'm having is that whenever I scroll the window (or move any of the smaller, additional windows) the program pauses what it's doing, and doesn't start again until I stop scrolling (or moving windows, or whatever).So is there any way to stop it pausing when you scroll or move windows?

View 2 RepliesWhat Difference Is Between Pausing / Resuming And Stopping / Starting A Service
Aug 25, 2010I am developing a Windows Service in VB2008 and am in the testing stage. What I have noticed is that if I Pause it while it is busy doing something and then resume it, the process generates an error. While I am debugging this I wanted to determine exactly what the difference is between Pausing/Resuming and Stopping/Starting a service.I searched, but most results simply told me how to Stop/Start/Pause and Resume a service, a hurdle that I jumped over many years ago. Does any one know of any resources that go into detail what happens when a service is stopped vs when it is paused?From some experimentation, it seems that if I do not place any code in the OnPause and OnContinue events the Pause/Resume commands have no effect.

what I want is when i hits certain value, like let's just say i is divisible by 365, then the 'while' looping will stop, and a message box saying "target reached" appear. then after I click button1, the looping will resume until it reaches the next number divisible by 365, and so on.
VS 2010 Auto Update Application Via A File Location Path & Pausing Splash Screen?
Jan 8, 20111. Just looking for some general help on how to auto update my application via a file location path (e.g. I have a HTML file containing the current file version and the .exe file to download)
What I need is to read in the HTML file version - DONE Check file version vs HTML file stream input - DONE Replace current .exe file with new .exe file - HAVING ISSUES WITH THIS
I know I have to close the application and then replace the old exe file with the new exe file then restart the application but looking for the best/safest way this can be done
2. Basically what I want is during my Splash screen which runs for 5 seconds I want to check if a network drive is mapped.
if not, pause splash screen ask user for address of drive, map drive then un-pause splash screen and continue with load how do I check if a network drive is mapped? and how do I pause the splash screen?

View 6 Replies.net - Accurate Windows Timer - System.Timers.Timer() Is Limited To 15 Msec
Jan 15, 2009I 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, 2009I 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, 2009I 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, 2011I 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, 2011I 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
