I am facing a lil bit of problem and my problem is I am calling a function in a timer device, and that function reads the data from the data base what it actually does is, first the timer capture hotkeys pressed from the keyboard and then calls a function Readit() and in Readit() it actually compares if the key has some data associated with it if it has some data it reads that data into a a variable buff and sends it to the active window whichever window is active.Main problem is my function won't stop reading and sending the same data to the active window,

I'm trying to implement a timer into my program, because I want to take a capture from a webcamdevice every x seconds.I've wandered around google all day and tried to implement all kind of timer classes (with system.threading because I can't use system.windows.forms.timer) but I won't figure it out!

View 1 RepliesAlright im trying to make it where in Visual Basic 2008 you click on a box ether 10, 20, or 30. Then that tells a timer that the program needs to turn off in 10, 20, or 30 minutes. What I basically want it to do is, whenever the set amount time is when it goes off it shows form1(login form). I have prepared a picture can anyone supply me with some information on how to do this?

View 2 RepliesI have created a 7 day timer in a VB form that is to be part of a larger project. It has 14 date time pickers set to hours and minutes only in 24 hour format (1 on and 1 off per day), 7 checkboxes, 7 radio buttons, 2 textboxes to display day of the week and current time and a few buttons. As a standalone project, this works well

I want the program to exit the sub after the timer has been started. But if theres no args, it should just show itself. The problem is that it seems to not care about the exit sub thingy, cause it shows itself anyway.
What i want to happen is for the dictionary keys and items to be overwritten each time it is executed, as the data needs to be up to date.

View 2 RepliesI am trying to write a small program that shows a clock using a timer in vb.net, I want the clock to display the time and date as a binary display i.e. if it's 10:01:21 the clock would display boxes or buttons in rows going from 1 to 2 to 4 etc upwards and changing colour when at certain times. the example time above would be a button for 8,a for 2 to make the 10 o'clock, a button for the 1 minute and a button for the 16, 4 and 1 seconds making 21 seconds.
View 1 RepliesI was making a little timer. When the phone is not in standby, my app is working fine. But when i put the phone in standby it stops. When phone is coming out of standby, the timer is going again on the time i put the phone in standby.
I know that other tools keep working, so i there a simple way to do that?
The code in question is in place, and it works. The project is all but wrapping up. That being said, I would love to find a better way to run this section of code in an x64 system so I have the solution ready for future projects. What I currently have in place is as follows:
Function TimeDelay(vDelay)
Dim vTimmer, vTargetTime
vTimmer = TimeValue(Now)

Now I know the easy way to achieve my goal would be to use the timer object in Visual Studio. The problem I ran into is I was developing an automated command line program. As such there was nothing I could attach the timer to (that I'm aware of). I just needed to pause the program for a few seconds to allow the DTSX package (SSIS file if you're not familiar) to load the file before I remove it from the staging folder.
While I was doing research for this issue I came across the old Sleep() function (referenced to a library in kernel32 as I understand it...never used this before either). When I tried to use this on my current system (64-bit system) I received stack overflow errors. Additional research lead to something called wow64, but I did not have enough time to fully research what this is / how to use it.
Out of curiosity, is there a way i can make a program stop or pause for a period of time (which i would choose) before continuing the code WITHOUT a timer.I think I've seen this done before, but I'm not positive.Also note that I'm talking about a forms application (not a console app if that would be any different.)

View 6 RepliesI 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.
How can I incorporate the timer so once a page loads the timer activates, waits a few seconds then I tell my program what to do next.I tried this code but it didnt work:

By the way is not a problem of mouse_event, is the timer that doesn't work
I have a timer in vb.net and it's interval is 1000ms ,. i have placed in it's timer_tick event a code that will print screen the screen and save it to a database.The problem is when i click outside of the form, or loosing the focus of the mouse to the form containing that timer/printscreen, the timer stops. As a result the printscreen also stops.here are it's properties:
generate member = true
interval = 1000
modifiers = friend
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
