Low Level GetTickCount?

Code:

---

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.

VB Code:

Imports System
Imports System.Environment
Public Module modmain
   Sub Main()
      'The KPD-Team 2001
      'URL: [url]http://www.allapi.net/dotnet/[/url]
      'E-Mail: [email][email protected][/email]
      Console.WriteLine("The number of minutes that " + _
        "have elapsed since the system was started " + _
        "is " + (TickCount/1000/60).ToString)
   End Sub
End Module

??? 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
