Can someone help me with the "How to" trigger a VBA code to set up a
menu if a particular workbook is opened?

The reason that I need this code is that I have a workbook that is
generate every week and would like to be able to generate a custom
menu that every time that this particular workbook is open is generate
a custom menu.

The only way that I can do this is by adding the vba code in
ThisWorkbook but because it is generate everytime the code is
override.

Suggestions please.
