how to get the processor type and speed of the user?
June 28, 2002 03:29 AM
i tried the GetSystemInfo(...) but can''t seem to figure out the way there,
i would like to use a Win32API for this, thanks!!

CPUID, dunno about speed.

There is no system property for speed, you''re going to have to write a program to measure it (run something like DXDiag, will give your CPU speed within a few mhz).

You can find a name in the registry under HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\CentralProcessor\0\VendorIdentifier. It is a string and contains GenuineIntel (no space) for Intel and AuthenticAMD (again no space) AMD. There are seeral other codes that you can find on the net. It is easier than using CPUID.

Check out other value in that key cuz there are things like ~Mhz and Identifier and name.

On a standard windows machine the information you can find is:
VendorIdentifier (ie. "GenuineIntel")
Identifier (ie. "x86 Family 6 Model 8 Stepping 6")
Update Status (a numeric value)
If you want information on what information is accessable about a processor read this article, ''cuz'' the CPU speed is not something that is reported by the chip, the only way to get the mhz is either 1) through a special program written for your specific motherboard or 2) by making a rough estimation, as programs like DXDiag do. With the right algorithm you can be within a 1-3 mhz of the exact speed.

Oh I''m sorry Michaelson. If my using "cuz" instead of "because" made the post hard for you to read or you had some other problem, you should have let me know cuz I owuld have changed it for you.

thanks guys,
i followed the sample on the MSDN, but i had a problem using the
RegQueryValueEx(hKey,
"~MHZ",
NULL,
NULL,
(LPBYTE)speed,
&dwBufLen);
because MHZ is not a string but a hex number, so how would i go fixin'' this?

DWORD Speed;
DWORD Type;
DWORD BufSize = sizeof (DWORD);
RegQueryValueEx(hKey,
"~MHZ",
NULL,
&Type,
(LPBYTE)&Speed,
&BufSize);
ASSERT(Type == REG_DWORD);
DWORD Type;
DWORD BufSize = sizeof (DWORD);
RegQueryValueEx(hKey,
"~MHZ",
NULL,
&Type,
(LPBYTE)&Speed,
&BufSize);
ASSERT(Type == REG_DWORD);
