- To anyone whom this touches... Dec 13th, 1992

- I am a Windows 3.1 programmer with a problem and I hope someone out there
- can provide some assistance. I deal with sampling systems that require
- very accurate timing for data collection. Currently, a DOS TSR is being
- used to track the internal timer, this is done because Windows' own timer
- routine is not very accurate in enhanced mode ( off by as much as
- 1 - 2 secs! ). Well the problem arises that we want to port this to NT or
- add in other features and TSR communication is not worth the hassle. So
- my question is can a device driver to hook the timer be a better alternative?
- If so how would I go about setting this up and does any one have source to
- do this? I already have a DDK, also which books would help in this area?
-
- On this same package I am wondering is there any way to check the system
- heap to see if I have any of my DLL's already loaded? Is it a function
- call or one of those undocumented Windows funcs?
-
- Many thanks in advance
