Hacking time down to fractions
Want to really get down to instants? This tip from reader Phil Lenoir tells you how.
The only way you can access fractions of a second in VB is using a Timer, Right? Wrong.
Use this simple technique to access time down to the resolution of the PC timer interrupt. It relies on the fact that Microsoft's internal time format is stored as a Double-precision number representing the number of years since 1900.
This code will pause for the requested fraction of a second:
Public Sub Pause(dblHowLong As Double) Dim dblPauseUntil As Double dblPauseUntil = CDbl(Now) + dblHowLong While cDbl(Now) < dblPauseUntil DoEvents Wend End Sub
