How do I get Hardware Info in C++/MFC?
Author
Hello, How do I get Hardware Info (CPU, VGA Card, RAM, Ports, etc, etc) in C++/MFC... Any suggestions... (links to some aritcals would really help)..
Look into the GetSystemInfo and GetSystemMetrics functions. Also the SYSTEM_INFO structure may be useful. They are Win32 (not MFC), but should give you a starting point.

Thanks, I am fetching:
1. processor information from: HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\CentralProcessor\0 .
2. RAM Info from: GlobalMemoryStatus()
3. Hard-Disk Info from: GetVolumeInformation()
Any suggestions about VGA, Sound Card and Ports (USB, Serial, Communication)...

Bye,
Dont know if you want to include the libraries just for graphics info but opengl/directx have functions which supply the information.
i'm sure theres a better way.

For vga cards I think EnumDisplayDevices will do the trick. And most devices seems to registered under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum.
For sound card you can use:
waveOutGetNumDevs
waveOutGetDevCaps
from mmsystem
However, if you do decide to use DirectX to query the hardware you can get a lot more information from direct sound and directshow. Also you can obviously use direct3d to get information about the graphics hardware. You can do similar with opengl.

I'm just trying it out myself now to get info from the ports, but I cant seem to get it working.
The code is pritty much just cut and pasted from msdn with bits filled in.
I get this output:
1295444344
1295444344

device name:\\?\acpi#pnp0501#1#{4d36e978-e325-11ce-bfc1-08002be10318}
error:13
failed1
But I cant see whats wrong.. (ERROR_INVALID_DATA?)
Anyway, I'm assuming I'm on the right track, so you just need to lookup the SetupDiCreateDeviceInfoList & related functions. If anyone manages to get something working please post the code.

Thanks a lot bro (aboeing), I'll not be working on that assignment for a week or so... (Actually have another assignment to make first, It's a game of NIM in MFC in which the computer always wins (or mostly wins) )
Will post the code for this one as soon as I start working on this one again (and most importantly, get anything working ;) )
Bye,
