Re: High res timer

This MSDN article also seems to show a decent example in Managed Code:

Is it possible to have a synchronous thread... actually a timer that is
beyond the 1khz/1ms resolution that .NET offers?

I want to poll the parallel port at rates beyond 1khz... about 10 to 100
times that rate if possible.

Essnetially I want to monitor the parallel port for data and display it
but I need a fast but somewhat precise way of knowing the sample rate.

Doing some tests on just a simple thread I can get speeds at around 150mhz
or so with a normal priority System.Thread. I figure that since I just
need about 1/1000 of that it shouldn't be that big a deal.

Is this possible in C#.NET? If not, is it possible to write a simple
driver in unmanaged C++ that either polls the port or hooks onto an
interrupt(synced) to get the data to a C# app?

Thanks,
Jon
