I have a UDF that refers to a range of data, for example, =My_UDF(A2:G45). I
would like to be able to relate a change in any cell in that range to the UDF
that is using that range, so that I can update the object the UDF is
controlling. I am trying to avoid using Application.Volatile because that is
overkill, but I want to "trap" changes to cells that affect my UDF.

For example, if I change the value of cell B24, then I would like to be able
to go into the Worksheet_Change event, relate the change in B24 to the UDF
that is referencing that cell (through the range A2:G45), and then do some
other stuff related to that UDF.

Question: Is there a way in VBA to determine what functions are referencing
any particular cell on a worksheet? I would like to be able to generate a
list of all the functions that use a particular cell. If my UDF uses a cell
that changes, I want to do some selective updating of the object controlled
by the UDF.

Thanks,

Eric
