>I'm not sure what you mean by "timers", the timer object in VFP or Window's own timer. I've always assumed that the timer object in VFP was merely a hook into the one that exists in Windows (that fires the screen saver, for example).
I'm not sure about this. I also believe that timers in VFP are a little "something else" than the OS timers, but I don't really know what's behind the scenes. I don't know how a VFP timer is implemented internally.
>Is this correct or are we talking about two different things?
1. Windows timers: they are different between Win3.x and Win95. That's sure.
2. VFP timers: the same as above.
Some differences are:
- A timer always stops when Enable = .f. in VFP3, but not in VFP5
- A timer always stops when Interval = 0 in VFP3, but not in VFP5
- A timer don't fire in VFP3 when a menu is opened (other actions as well), but it fires in VFP5
- The minimum timer interval is about 50ms in VFP3, 1-2ms in VFP5
- The average interval is much more reliable in VFP5 than VFP3 (the real interval is almost never exactly the one you set in the Interval property)
There are many other differences. Basically, when passing from VFP3 to VFP5, any timer must be retested very carefully.
Anyway, timers are more reliable in VFP5 (except that the only sure way to stop a timer is to destroy it).
There are also differences between VFP5 timers on Win95 and WinNT. Ie: more reliable on NT.
