Getting System Information

By , 11 Jun 2001
 

Sample Image - SysInfo--Processor.jpg

Introduction

Have you ever wanted to get system information on the WIN32 platform, but you just want a C++ console interface? Now you can with SysInfo and its related classes.

The class itself is really easy to use. SysInfo has a number of helper classes that do all of the work. SysInfo itself is just the interface to these other classes. If your needs dictate only a subset of what SysInfo provides, you don't have to use SysInfo. The other classes are in the global namespace so you can access them as well. Full source code is included.

GeneralMissing licencememberFrederic Souchu25 Oct '10 - 22:30 
Hi,
Would it be possible to precise the licence for this article?
This is increasingly necessary if source code is to used in another product (commercial or not)!
Regards
Frederic

Please provide me Visual C++ code that tell which hard drive is primary master, which is primary slave, which is secondary master and which one is secondary slave.
 
I really need that. Thanks in advance.

GeneralSome more featuresmembertyjjrtruy4teqye7nyue7qay9 Feb '07 - 1:23 
Hello sir,
First of all i would like to thank you for posting such a wonderful article with a code of great modularity.
I am developing an application to retrieve all hardware information as much as it is possible.Can you mail me revised version which includes information about motherboard,keyboard,mouse,PCI,ISA cards,network cards,usb devices,serial ports,parrelel ports etc..
Can u suggest me the books through which i can learn all these things?
Your help will be greatly helpful to me.
Thank you again.
Dhiren.

GeneralRe: Some more featuresmemberPaulWendt9 Feb '07 - 4:21 
When this was written, many years ago, there was no built-in support for determining a lot of this stuff with an easy-to-use API. Nowadays, that's not entirely true and I feel there are probably better ways to do a lot of this. There's a motherboard/CPU detection library free for the taking [as far as I know]; check out CPU-Z.
 
The main reason I stopped working on this is that WMI provides most, if not all, of this information and since Windows 2000, this is on every Windows machine. So, check out WMI for your hardware-detection needs.
 
The best part of this project is that it can be used as a demonstration for how to wrap inline assembly into function calls so that the __asm doesn't have to be looked at by people who'd get confused by it [like me Smile | :) ].

GeneralRe: Some more featuresmembertyjjrtruy4teqye7nyue7qay12 Feb '07 - 2:12 
Thank you sir,
I have already tried WMI to find all these information,but some information like-motherboard's manufacturer,version no.,serial no.,HDD's serial no.,revision no.,Floppy drive's serial no,manufacturer. etc. are not reliable through WMI. It doesn't give consistency in performance in large network. so can u suggest me some other way to look through??I want the direction to get ahead only.
 
Thanking you.
Waiting for reply.
 

Dhiren.

Sorry, I don't know of a way to get the things you need. I know CPU-Z gets some of it, but not all. I've seen posts on here and CodeGuru regarding getting a hard drive's serial #.
 
Good luck to you.
