Adding the Spectral Analysis Menu Item to Excel

The last step in the integration process adds a menu item to Excel so that

you can open the tool from the Excel Tools menu. To do this you add event

handlers for the workbook’s

AddinInstall and AddinUninstall events that

install and uninstall menu items. The menu item calls the

LoadFourier

function in the FourierMain module.

Follow these steps to implement the menu ite m:

1 Right-click the ThisWorkbook item in the VBA project window and click

View Code.
