I 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 currently have a browser go through the same list of sites one by one and gather updates. The problem though this takes awhile. Can a browser be multithreaded, (so it could visit several sites at a time) and if so would this take up a lot of server resources?
View 2 RepliesRecently in a couple of my current projects I have found that I have the need to 'schedule' events in my applications. For example, I would like something to happen in my program at 11 PM every day (and no I dont want to use Windows Scheduled Tasks) but I cant think of a good way to do this... The only method I can think of is to just have my app check every minute to see if the current system time is 11 PM but obviously that is pretty rubbish. I considered using Windows WorkFlow but that seems very overkill just to do this one thing...
Oh and if it makes any difference, I would like the user to be able to modify these times that certain events occur.
When I run my app at first its keeps time accurately for the first minute or so there after it starts loosing seconds, and by the end of the day its minutes behind.I've created a class called ServerTimeTimer that has a timers.timer object that elapses every second and adds a second to a dateTime variable, and a property to retrieve the date time.[code]

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 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?
