CPU usage

• Demonstration
• Description:
  • Real time CPU usage graph
• Functionality:
  • Graph is updated every single second
  • Actual CPU usage value is presented in the window's caption
  • Graph features:
    • graph is scaled to the window's height (0% - bottom of the client area, 100% - top of the client area)
    • horizontal scale is constant, one value per pixel
    • new measures are added at the right edge of the graph
    • measure history should be enough to show maximized window
• Hints:
  • GetSystemTimes(), __int64
  • CPU usage formula: (kernelTime + userTime - idleTime) / (kernelTime + userTime) * 100
