Timer event fires irregurarly
I'm trying to create a simple performance logging function in my script tests. What I want to do is to set a timer that will call this logging function regularly during the entire program run, and eac...

Thank you very much for your reply :)
I'm running automated endurance/stress tests on a desktop application and want to log information about that process and the hardware utilization. So it seems like it won't be easy to get well-timed readings by using timers, based on your trying in getting correctly fired events in a simple application such as Notepad.
I started looking into Performance Monitor after I concluded that the timer objects won't give me the precision I need, since it's also not giving me reproducable results by firing at "random". I looked for possibilites to run perfmon from withing TC, but didn't really find anything. Therefore I did a simple automation script for starting monitoring via the GUI, which is where I'm currently at.
However, your way of calling perfmon from within the script sure looks interesting, especially the fact that you can access measured data so easily :)
How do I learn about using the WMI service in this manner? How/where do I learn how to use and what to access in the perfmon process? When using the perfmon GUI, there are tonnes of performance counters to choose from, and I figure that not all of these can be active...
The most important question might be if it's possible to just start perfmon from withing TC in this manner, and then let perfmon do its thing and log data in a way that I tell it do, instead of me collecting data into variables inside the script? 'Cause I guess I'll fall back into the timer accuracy issues again if I start collecting monitoring data from the perfmon process in TC (since this would correspond to my initial approach described in the first post).
So would it be possible to just call perfmon and set certain parameters for deciding what it should monitor, and then let it run by itself without having to gather data from it through the script?
I have started working with Excel sheets and charts that visualize my gathered data, so I don't really have a need for keeping the monitored data inside of TC.
An alternative approach that crossed my mind earlier, when dealing with the non-accurate timers, was to do an asynchronous call to a logging function that locked its control flow inside a never-ending loop that only return when the process it monitors is dead. This loop would then sleep/delay for a specific time interval and thus act as a monitor.
The issue about this quite ugly approach was that it didn't seem to be possible to call script unit functions - only object methods/properties.
