How would I take a textbox (textbox2.text) and make it show what part of the interval the timer is on? like how do I watch the timer while its counting?
I'm trying to work out a program where you can set up a variable amount of timers (like egg timers). Each timer works independently of the other (you can stop a timer, reset another, and so on, and the rest are not effected).I thought of using a single timer and then creating a custom egg timer class to handle the countdown, store the current time, etc, and use a collection of these classes inside a timer event (at the tick, do a for each to reduce the countdown on the classes by some milliseconds).Then I got to thinking: all of these egg timer classes in the collection with the for each loop may cause some accuracy loss (say, I add 50 egg timers).
Does anyone think the accuracy loss for updating all of the egg timers would be too adverse? Should I try running them on separate threads (have not thought about how yet), or will that make much difference?
I am using timers in a windows service and facing problem that anytime some exception happens ( say i unplug LAN wire from my computer ) service stops running, What i am expecting is that service should keep on running as i am catching generic exception which should catch the exception on one tick event and again work (next tick)when i plug in LAN wire (i am plugging/un plugging ) LAN wire as this service is reading database from LAN so i want to replicate a failover scneario)
View 3 RepliesI working on a scoreboard application for class that would control a scoreboard like you would see at a football game. My problem is that I'm not sure exactly how to work with timers. I would like a timer to start at either 15 or 12 minutes and count down the quarter. I'd like to be able to pause the timer, have it count up in case I need to add time to the clock.

I don't know if I worded this properly, but I have a mdb query that I display in a Datagrid on my form. The first column is TransactionNumber, which is the primary key and a running total (ex. RackingTransactionKey=RackingTransactionKey + 1). What I need to do is when the form is opened, find the highest (last) TransactionNumber from the query or Datagrid and assign it to a variable (RackingTransactionKey), so I can can update it (+1), therefore generating a unique number so I can add data to the query.

I'm trying to make a program that can export my schedule into a CSV file to upload on to google calender.I need to extract some text within a textbox control. I'll show you an example.This is the text in the textbox:
Quote:
Monday, 10 January, 2011
09:45 - 18:00
Phone Work09:45 - 12:15
[code]....
I need to get just the date and times from this list, and put them in variables. so that I'll end up with:
1) A string with a value as a date, which would be "10 January, 2011" for example: strDate1 would have the value of "10 January, 2011"
2) A start time, for example: strStartTime1 would have the value of 9:45
3) An end time, for example strEndTime1 would have the value of 18:00
I have declared a String variable(PC) for use within another String variable(currentQuery) to form a SQL statement to pass to my SQLDataAdapter variable.
I'm performing this action to change the string variable(PC) for the different onClick events I have.
It seems i can change this variable (PC) within my onClick event handlers and the 'PC' variable will change when I apply it to a testing Text Box 'testTextBox' but not for the currentQuery variable.
Do i need to perform this action as a function or am i missing something obvious - code below - I don't want to spend time writing a function to return a string value for my SQL statement if i can just tweek something in my code (below).

I will have a directory of files (IFO, BUP, and VOB; DVD files for anyone who cares), I need to find the first one by sorting these like this: Filter out everything that does not have a .VOB in it, then find the one like this VTS_**_1.VOB. It will always have a "1" before the extension, but the two numbers before that change, lastly I need that file returned as a variable.

All the code needs to be controled by seperate timers as the user may need to pause timer3 or timer4 at any one time. The problem I have is that after about 5 minutes the time and elapsed time are about three seconds ahead of the two count down timers.
I'm developing an application to learning purposes only. The application will check some proxies that are in a proxy list.
I did a For Each loop ( to run all the proxies in the listbox ). The problem is some proxies are slow to answer and I must do the application wait some seconds before get the next proxy.
I tired a sleep thread but I don't want the application to be unanswering. There's any chance to help me with the timers?
I tried all possible ways and searched a lot but my problem is each time the timer ticks, it make the full for each loop again instead waiting.
basically what im doing is something similar to this;
Private Sub FirstRoutine()

I have the system tray icon changing pictures based off a timer..and when I check my page faults they go up on every tick ofthe timer.. so then I pull out the changing of the picture thinkingthat was it.. but still page faults increase..so just wondering if timers have issues ?this was a timer from VB6 ? is there a new timer I should use from.net.. delete the old and use a new control ? I have a couple sobefore I switch them all out.. figure I would find out first..

View 5 RepliesI am using vb 2008 I am trying to learn loops and timers but I have some problems. [Code] The problem with this is it does not wait it just sends 123 all at the same time. I tried using the other way the one that makes the program freeze for the amount of time I want it to wait, but I don't want the program to freeze I want to to move my mouse ext whilst its doing it. as for the loop this is as far as I got I cant really test it yet cos my program is typing 123 a million times a second and my pc doesn't like that so i need to fix the timers.

View 7 RepliesI created a timer in the main form - form1 which then updates some text in form2 each 100ms. Now When I click a button in form1, the timer stops. Why? Happens no matter if timers are on or off by default. I have to open/close form2 to make my status updates work again - that's where I run the timer on form load and stop the timer on form close.
Was doing it in windows 2010 express.
So this is what I have in form1:

View 4 RepliesI have a background application with a couple of System.Timers.Timer running in it. I also have a NotifyIcon that when double clicked brings up a windows form.
My problem is that sometimes my form gets displayed but then for whatever reason it seems like it's losing focus and becomes un-usable (it just sits there in the background).
So here comes the question now... Can the freeze be caused by the form loading (i.e. me double clicking my NotifyIcon) and the timer tick happening the same time?

View 12 RepliesI'm considering making an application that will perform various tests against servers on a local network - for example pinging them, checking hard drive space, checking the state of services, whether or not databases are available, etc etc. Very similar to Hostmonitor if anyone has ever used that - but my app will be free
These tests would have to be performed at specified intervals, but the problem is that there could be literally hundreds of tests and I'm not sure how well my app would cope with hundreds of timers running... especially if they are all configured to run every minute or two (they all need to run independently of each other).
Really I'm just wondering how you guys would design such a system.The best way I can think of is to have a separate timer associated with every test and then when a test's timer has elapsed use the ThreadPool to do the work that the test will perform. That way if loads of them happen to run at the same time then the ThreadPool will queue them rather than trying to run say 200 at once. I also think I would need to have some kind of staging for when the app first starts, so that every single test is not going to have the exact same time to run (well, every test that has the same interval configured), but that shouldn't be too much of an issue.I guess it would be a good idea to try and use some sort of grouping so that more than one test can use the same timer - like if 20 tests were set to run with a 5 minute interval then I could use one timer and run all of the tests when that one timer fires.
