Remarks

This sample builds a replacement to the calculator that is shipped with every Microsoft Windows machine. It provides the following advantages over the Windows calculator:

  • It provides a history trail.
  • ToolTips for some operations (such as percent, memory buttons).
  • It shows the current value that is stored in memory.
  • It allows the user to use keyboard strokes in addition to the onscreen buttons.
  • Buttons are drawn using styles and animation and are written in XAML.
  • It prevents the user from entering invalid numbers.
