In VBA you can
Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)
to provide yourself with a sleep routine.
However, the Long that must be passed to the routine appears to overflow for values in excess of 32000 milliseconds.
Is there a way to sleep for longer periods of time without the complexity of stringing together several consecutive calls to the sleep routine?
回答1:
No, it doesn't overflow, unless your code that calculates required number of milliseconds causes an overflow.
Example:
dim t as long
t = 10000 * 10000 / 10000 'Overflow
Example 2:
dim t as long
t = 10000! * 10000 / 10000 'Ok
