So a timer's maximum interval is 1 which is a thousand ticks a second. A Stopwatch's frequency is 2238906 ticks a second on my pc...
I am wondering if there is a reliable way to trigger an event for each tick of the stopwatch without missing any ticks...
If I can somehow get a Tick event for the stopwatch, I believe I can increase the resolution of my input recorder....
Is it possible to trigger event whenever seconds on stopwatch change (that means every second, but it has to be synchronized with seconds)?

View 3 RepliesI have a control thread that starts up a secondary thread and when the secondary thread finishes, the control thread restarts the secondary thread. On this secondary thread, I use a stopwatch to record a thread.sleep event. Is there any reason, under any circumstance, why the stopwatch elapsed millisecond value (499) would be 1ms less than the sleep time (500 ms)This doesn't happen all the time or even a lot, I'm just curious if there is any physical reason for this to happen.
View 1 RepliesI am setting a timer interval of (Hours):
Timer1.Interval = ((CInt(ComboBox24.SelectedItem.ToString()) * 60 * 60) * 1000)
And then calculating the next DateTime that the ticks event will fire using:
MessageBox.Show("Next Timer Will Occur At: " & New Date(DateTime.Now.Ticks + Timer1.Interval))
Each time I call the MessageBox it shows me that the next event will fire now (Exact date, hour, minute, second).I can't see where I have gone wrong here as when I simply messagebox'd the calculation it clearly showed separate numbers (ticks) & by a large amount.

View 2 RepliesI have an access database that has columns where the data is a tickbox, i would like to select all the ticks from one row. Erm i'll try and be more descriptive: The database has the family of aircraft in the first column and then each subsequent column is to do with a calculation and i want to assign boolean variables the value of true if the tick box is checked and false if it isnt. How can i assign the values of the tick box to a variable?
I have this query:

View 9 RepliesI have a VB.NET app in which I'd like to use the Stopwatch class. The stopwatch will get reset every time it enters a particular method, which may be in less than a second, or not for hours. Is there a limit to how long you can let a stopwatch run before something bad happens? i.e. an error, or performance degradation?

I want to list the split times in a list box as the user presses the split button and also display the final split time when the user presses the stop button. I feel I'm real close but just can't get over the hump, especially trying to code in OOP. The rest of my program works fine (start, stop, elapsed time). I am programming in VB 2005 and will display my relative code from both the class and form areas.

ETA: Using Environment.TickCount does not present the same problem. ETA2: I should add that I don't actually use the Forms.Timer in my app - as this would negate the use of a high frequency timer. I've used it here to simplify the code. ETA3: I've published a workaround as an answer below.

I am using Timer control as a stopwatch to populate couple of Label controls text field. I am listing the code below which is not updating the Label fields. I have removed the code related to buttons and other controls. Why is the Timer1_Tick not being invoked? The code is compiling clean and when I walked thru the debugger, my Start_Timer() and Stop_Timer() subroutines are working. However, nothing is happening in the Timer1_Tick() subroutine.
