1. What can I/O bytes of a process be obtained? Dizzy .....
2. If you want to use getprocesstimes under 98 and want to use the process, why not?

Obtain from WMI. Everything you want, from soft to hard. Haha/

WMI is a good stuff!

..

Select readtransfercount from win32_process where caption = 'your process name'

This library is too slow. You can use ntquerysystem.pdf!
But how can this function obtain the running parameters of a process? Who can tell me!

Ntquerysystemfound! Solved by yourself .... Thank you ....
