CPU utilization for a particular process

[ken gray]

Is there a way to get the CPU utilization for a particular process?

Function GetProcessCpuUsage

Code:

Copy      Help

[color=green];/[/color]
[color=blue]function[/color]# hwnd

[color=green];Returns CPU usage (0 - 100 %) of program to which belongs window hwnd.
;Measure time is 100 ms. Precision is 10% or worse. Doesn't work on Win 98/Me.[/color]

[color=green];EXAMPLE
;int hwnd=win("Windows Media Player")
;rep[/color]
,[color=green];1[/color]
,[color=green];out GetProcessCpuUsage(hwnd)[/color]


[color=blue]#if[/color] _winnt
[color=blue]#compile[/color] "toolhelp"
[color=blue]dll [/color]kernel32 #GetProcessTimes hProcess FILETIME*lpCreationTime FILETIME*lpExitTime FILETIME*lpKernelTime FILETIME*lpUserTime

[color=blue]int [/color]pid hp
[color=blue]long [/color]tce tkernel tuser t1 t2

GetWindowThreadProcessId(hwnd &pid)
hp=OpenProcess(PROCESS_QUERY_INFORMATION 0 pid); [color=blue]if[/color](!hp) [color=blue]end [/color]ES_FAILED

[color=blue]opt [/color]waitmsg -1
GetProcessTimes hp +&tce +&tce +&tkernel +&tuser
t1=tkernel+tuser
0.1
GetProcessTimes hp +&tce +&tce +&tkernel +&tuser
t2=tkernel+tuser

CloseHandle hp

t2-t1
t2/10000
[color=blue]if[/color](t2>100) t2=100
[color=blue]ret [/color]t2

what am i doing wrong here?
i keep getting "Error (RT) in CPU_Notice: failed"

Code:

Copy      Help

int hwnd=win("Crystal Reports")
int a b
rep
    a=(GetProcessCpuUsage(hwnd))
    5
    b=(GetProcessCpuUsage(hwnd))
    if a+b=0
        mes("Crystal Reports is done." "CPU Notice" "i")
        end

thanks

Probably the window is closed. Use IsWindow to test whether hwnd is still valid. Or use err.

This code shows error description:

a=GetProcessCpuUsage(hwnd)
err out _s.dllerror

hmmmm..... it was running but maybe an issue with the virtual desktop thing (i ditched litestep and went with VirtuaWin V2.10 from Sourceforge (so you know it's completly bug proof)).
:wink:


thanks

How would I get the total system CPU usage ?
