MFC(C++) CPU, memory check question.

Leave program number 1 (ex: Test program) running (just for CPU state, memory state change)

Run program number 2 (ex: check program)

Select the program you want to monitor as program number 1 and

The current time, CPU state, and memory state of program number 1 every 1 second

Display the value in the second program list control (View: Report)

You want to create a program that leaves a log with a *.txt file.

I can't feel it because I'm trying to implement it unemployed

Is this possible?

Please advise me how to code.

I have a few additional questions.

I've implemented almost everything, but there's a blockage in the CPU status check part, so I'm posting it.

double CCheckUtilDlg::getCPU()
{
    FILETIME ftime, fsys, fuser;
    ULARGE_INTEGER now, sys, user;
    double percent;

    GetSystemTimeAsFileTime(&ftime);
    memcpy(&now, &ftime, sizeof(FILETIME));

    GetProcessTimes(self, &ftime, &ftime, &fsys, &fuser);
    memcpy(&sys, &fsys, sizeof(FILETIME));
    memcpy(&user, &fuser, sizeof(FILETIME));

    **percent = (sys.QuadPart - lastSysCPU.QuadPart) + (user.QuadPart - lastUserCPU.QuadPart);**
    **percent /= (now.QuadPart - lastCPU.QuadPart);**
    **percent /= numProcessors;**

    lastCPU = now;
    lastUserCPU = user;
    lastSysCPU = sys;

    return percent * 100;
}

In the percent calculation part,

"warning C4244: '=': Data may be lost while converting from 'ULONGLONG' to 'double'. "

Whether the warning solution and percent calculation formula are correct

(The calculated value of the first line is almost 0, and the percent value of the zero is divided by

-1.#IND0000000000000000 This value is displayed.)

Finally,

I wonder if the calculated value in the formula is the average CPU value in red squares.

If not, I wonder how to read the average CPU value.
