Wrapping of GetTickCount in VB
Posted on 2002-05-20
VB documentation states that getTickCount recycles after about 49 days, which is the range of unsigned long.
“The elapsed time is stored as a DWORD value. Therefore, the time will wrap around to zero if the system is run continuously for 49.7 days. “ (MSDN)
VB’s long is SIGNED and therefore it seems logical to me that the recycling will either be at half the period:
2,147,483,647 / (1000 * 60 * 60 * 24) = 24.85 days
or that it wraps to the negative range of the long var.
I need to know whether in VB, getTickCount wraps to negative numbers after 24.85 days, and if so, exactly how it is done.
An attached article will add 100 points to the 250 I am giving.
