Minimum time per interval

[Edmund Seet]

'The below sample line represents 2 minutes interval
Public Const cRunIntervalSeconds = 120 ' two minutes

I'm just curious what's the "minimum" interval that VBA
can accept?
0.1 sec?
0.01 sec?
0.001 sec?
0.0001 sec?
0.00001 sec or something else?

TIA

Hi Patrick,

Have you any example code of how to get Excel to use .001 seconds in Vb such
as using the "Application.Wait" method.

Thanks,
Rocky McKinley

Rocky,

Use the Sleep API call for smaller time interval. It takes as its argument
the number of milleseconds.

Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)
Sub Test()
Sleep dwMilliseconds:=100&
End Sub

Thanks Chip that works great! Where can I find out more about API calls so
I can utilize more of their powers.

Rocky,

You can read the API reference at

Examples in VB for many APIs can be found at
