Overview
The COXSysInfo class is an easy way to have an application query a computer for system information. Various system parameters can be examined using this utility class.
This sample program shows most of the functionality of the COXSysInfo class.
Several system parameters are listed, showing the abilities of the class.
Features
- Can query computer name, user name and current IP address.
- Can get Windows version, Windows folder, System folder and Temp folder.
- Can get information about a drive (type and free space available).
- Can get information about the current display resolution and number of colors.
- Can get information about the current memory usage.
- Can get system information about the number of CPUs and their types.
The sample simply creates a member COXSysInfo m_oxSysInfo object (include OXSysInfo.h) then calls a member GetSystemInformation to query various categories of system attributes and populate a tree control:

Initial CodeProject release August 2007.
In January 2005, David Cunningham and Chris Maunder created TheUltimateToolbox.com, a new group dedicated to the continued development, support and growth of Dundas Software’s award winning line of MFC, C++ and ActiveX control products.
Ultimate Grid for MFC, Ultimate Toolbox for MFC, and Ultimate TCP/IP have been stalwarts of C++/MFC development for a decade. Thousands of developers have used these products to speed their time to market, improve the quality of their finished products, and enhance the reliability and flexibility of their software.
