How to Retrieve Physical memory.

Keywords: total Physical available memory 

See the Process Extender functions. You can approximate the physical memory on a machine by querying the following performance counters and summing the total of the 3 following counters:

Memory\Available Bytes
Memory\Cache Bytes
Process\Working Set\ _Total 

NOTE: this code can be used to get physical memory on Local *or* Remote machines....

AddExtender("wwprc44I.dll")
if WinVersion(4) == 4; NT
   availablebytes = tGetData("\\Machine\Memory\Available bytes",0)/1024
   cachebytes = tGetData("\\Machine\Memory\Cache bytes",0)/1024
   totalworkset = tGetData("\\Machine\Process(_Total)\Working Set",0)/1024
   physicalmemMB = (availablebytes + cachebytes + totalworkset)/1024
   str = strcat("Available bytes     : ",availablebytes,@CRLF,"Cache bytes         : ",cachebytes,@CRLF,"Working set total  : ", totalworkset,@CRLF,"_______________________",@CRLF,"Physical Memory (MB): ",physicalmemMB)
   Message("Approximation of Physical Memory",str)
else
  Message("tGetData", "Is designed to run on NT")
endif
exit

This code automates the Control panel applets with the Control manager extender.
