Timer Control
VBA has no timer control built-in (obviously, I assume you are talking AutoCAD VBA. Other VBA may provide something that can be used as "timer", such as in Excel VBA, there is Application.OnTime() method that can be used to play the role of timer). If you have to use some kind of timer inside AutoCAD VBA, you probably need to look into raw Windows API (quite complicated, to most VBA coders), or try to find third party existing component (I'd not hold breath for this, because what you need is 64-bit one).
If yo are doing fairly complicated/advanced/mission-critical development with AutoCAD, I'd say. stop waste time on AutoCAD VBA.
