How can I build a menu on the fly. What I need is to place the menu Item onto the menu and have it execute some code but how can I add the menu and assign some code to it???

eg.
Read in from data source:
ReportLocation = "Reports\SomeInfo"
ReportEXE = "ReportViewer.exe someinfo.rpt"


What I want to do is see if there is a menu called Reports if not add it. Then check if SomeInfo exists, if not add to it the menu, and have it perform a sub with the ReportEXE as the paramater. How can I do this?
