Low Level GetTickCount?

[JoshT]

Private Declare Function NtGetTickCount Lib "ntdll.dll" () As Long

seems to work fine for me under Windows 2000. Anyone know how to tell for sure if the Win32 GetTickCount API is a wrapper around this native API? Because if its a lower level, it might be somewhat more efficient for debug time testing. Then again, the 10ms resolution of accuracy might cancel out a difference.

Thanks.

??? What does that have to do with my question?

The most efficient high-resolution timer is QueryPerformanceCounter. I believe it's accurate down to the nanosecond.

And it's supported in both WinNT and Win9x.

Shawn, its that VB.NET?

i come across that the nanosecond, but it also depend on the hardware right? Meg

I don't know what I was thinking. Yea, that's VB.Net
