<!-- Add the rest of your HTML here -->

Introduction

This program shows you a very simple way to determine your PC hardware and software. It queries operating system for the following Hardware/Software:

  • Operating System Version (Thanks to PJ Naughter)
  • Computer Name
  • IP Address of Computer
  • User Name
  • Internet Explorer Version
  • Total RAM
  • Free Memory
  • Number of Hard Disk Drives
  • Hard Disk Total Space/Free Space/Used Space
  • CDROM Drives
  • Monitor Resolution
  • Color Depth
  • Number of CPUs (Thanks to Iain Chesworth)
  • CPU Speed
  • CPU Identifier
  • CPU Vendor Identifier
  • Operating System Folder
  • System Folder

Program structure

By clicking the combo box and changing it's item, selected item is determined and it's ID passed to Process member function of dialog. The Process member function takes ID of query and returns the proper result. Body of Process has a lot of code to prepares result and if any error has occurred, the error string will be returned.

How to use

Add the following header and implementation files to your project:
  • cup_info.h, cpu_info.cpp: For CPU Information like Speed, ID, Vendor ID,...
  • dtwinver.h, dtwinver.cpp: For Operating System Version (e.g. Build Number and Service Packs)
  • SysInfoDefs.h, SysInfoDefs.cpp: For General System Information like Total RAM, Number of Hard Disk Drives, Disk Space/Free Space/Used Space
  • SmartDef.h: For IDE S.M.A.R.T. commands to query from IDE hard disks that support SMART.

Functions

Below table shows all functions that are used to determine Hardware/Software of the computer.

CString DetermineIEVer(); Determining Internet Explorer Version (Build Number)

CString QueryResolution(); Calculating Monitor Resolution in Pixel
CString QueryPixelDepth(); Calculating Color Depth of any Pixel
CString QueryOS(); Determining Operating System Version (Build Number) and it's Service Pack
CString QueryLocalIPAddress(); Determining IP Address of Computer
