Can I use timer for nanoseconds???

[McRight2k]

Hi!

Is possible make a delay in nanoseconds??

Thank's

whats the use? it wont be noticed.
but i think it might be possible with windows api calls (my weak subject).

Known is handfull, Unknown is worldfull

I don't think that's possible without added hardware.
Anyway have a look at Karl E. Peterson's high-resolution
timer replacement for VB

I don't think there is any place on a PC motherboard where frequencies in the GHz range are exposed. Although the CPUs operate internally at frequencies that high, isn't it done within the chip by multiplying the bus frequency?

Anyway, I've just got to ask, what do you want a delay measured in billionths of a second for?

In theory yes, in practice under Windows it really isn't that useful or practible

it's for test an algorithm for program a flash. I'm using the parallel port with the portio dll.

Already there are programs that make it, and I've the steps for program it, but I need make a clock for data transfer.

I'll look this timer later and post results.

thank's

You can use a for next loop for a delay
dim a as byte (or integer or double for longer delays)
IOPort on
for a=1 to N
next
IOPortOff
will give you a very short pulse depending on the value of N
but it depends on your processor speed
