I have insert a map of USA in Excel (MapPoint in Excel) in
a worksheet in Excel. I have insert the name of each state
in this map. If i select a state, i have the name of this
state. I would like to launch a sub when i click on a
state like if i select Arizona, i have Sub Arizona_Click
but it's not possible but do you have a solution ?.

MapPoint is fully programmable from within an Excel macro/VBA
code. There are several example on MP2Kmag, this is probably
the most basic example:

You might find a number of other examples by searching like
