I would like to close my program based on the system time. I have stuck a timer on my form and I want to set my timer to my systems time. if the timer = "8:00" pm or timer = 20:00 hrs then END Does any one have the code on this? If I could do it without the timer as in to check the systems time = 8:00 pm or 20:00 hrs then End
View 7 RepliesI 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

View 4 RepliesI'm working on a reaction time program where I'll be testing... well, reaction time of a user. For this program I'll need a timer to stop at a random time interval, say somewhere between 3 and 10 seconds. Anyone know of a technique to do this. I've done some research and it seems there are a bunch of different ways of generating a random number just not sure how to assign that number to a timer.
View 6 RepliesI have a basic question about timers, that I can't answer myself. It's annoying me. My code is made to visit a website every X seconds. There are two problems.
I Set the interval for 30 sec and the first visit should be right now, not after 30 seconds.
After that, wait 30 sec and navigate to another one (in a listbox). The problem is that the Timer is not waiting that time after the first visit.[code...]
I have an application that I'm writing that needs to run 3 different Timers. One that will run every 5 minutes, 1 that will run every hour and 1 that has to run once a day sometime after 5:00 P.M. I know that I can seperate the application into 3 seperate applications and use Windows Scheduled Tasks to perform this however I would prefer to have everything in 1 application and just run the different Sub/Functions off of the appropriate Timer. I'm trying also figure out a way to avoid 2 timers firing at the same time.
What i would like to do is tell the 5 minute timer to run say 2 minutes after every 5 minute mark in the our so the first one would be at 12:07 and then the next would be at 12:12 and so on. The hour timer should run sa at 12:20. The daily one run at say 5:31.Is it possible to use the System.timer or the System.Threading.timer in this way?
I'm trying to program a countdown timer that shows the time in a label, with a button to start it, and if the button is pressed again add certain amount of time, for example 1 minute.
View 4 RepliesI'm currently writing a countdown timer on vb 2005, with the following characteristics: When I press a button and the timer is running, it adds time to the counter, for example, if the time is 2:30 and I press a button, and the period to add is 1:10, the new time would be 4:40. The window is always on top of every other window, and is active even though it doesn't have focus. When the time's up and i press a key, in this case Esc, the application closes, otherwise, it just continues. [Code]

View 2 RepliesIm using the express edition of VB.Net to do my project. I have several threads in my program which run fine. However, im stuck at this problem. I have a button in my form, which if I click I will call ThreadA (works fine), If i keep it pressed for more than 2 sec i need to call ThreadB (doesnt work), and if the time is more than 2 min, i need to stop and send a msg to the user. I have tried the timer to calculate the elapsed time, so the tick function would call the thread. BUT this doesnt work... Im not sure what do to.

i have a timer that counts down from 2 hours, its part of a 2 hour time limit for a computer. but if the application was to fail it would restart from 2 hours again. which isnt good, so it needs to restart where it left of. so far i have got it to save the current time on the countdown timer to a reg key. but i need to put that time back hope that made sense. here is the part of my code
Dim LLT As DateTime
Dim HReg1 As Object
HReg1 = CreateObject("Wscript.shell")

Looking at the timeoutOccured() sub, you can see I'm unsure of how to specify which index to set. Efficiency is important since this will be housing a lot of connections at once. Something else that just came to mind, would .theTimer.Stop reset the tick value on the timer?
