I don't quite understand what you are trying to achieve, but "Me" can refer
to any class (here FMain or maclasse).
So, even when your variable name stays the same (varfct), you are
essentially doing the same as this:

FMain.maprocedure
maclasse.maprocedure

or perhaps more enlightingly:

Dim hObj as object

hObj = FMain
hObj.maprocedure

hObj = maclasse
hObj.maprocedure
