Sorry I didn't reply right away. Here's the straight WMI code I'm
using:
c = wmi.WMI()
for i in c.Win32_ComputerSystem():
mem = int(i.TotalPhysicalMemory)
compname = i.Name
for i in c.Win32_Processor ():
cputype = i.Name
This code was wrapped in your CoInitialize com objects.
Let me know if you need more code.
Mike
