so how do you compare to some expected range. I couldn't change the variable to unsigned long here because the tag's use integers, unless I didn't use tags or modfied them.

Do you do something like:

Code: Show/Hide if (time2 - time1 < tolerance && time1 - time2 > -tolerance)

[Mr Ekted]

If you have a known base, like start_time = GetTickCount(), then at some point in the future, you can do GetTickCount() - start_time >= SOME_INTERVAL. This will always work even if the values wrap, because the difference also wraps.

0x00000001 - 0xffffffff = 2

If MERV tags are 32-bit ints, then you can simply cast ticks back and forth to unsigned ints. No change of bits is performed, just change of interpretation.

that's what it's doing. The problem is that if the tag isn't found it'll default to 0.

so curTime = -124114 and
lastWarpTime = 0

curTime - lastWarpTime is -124114 which is < 100 (tolerance).

but with centiseconds the value will never be negative, so the problem is solved.
