Volatile functions

I

Iain

Hi

I've asked this question before, but didn't get a response, so I'll
try again.

What I am trying to do is make a function in an add-in VOLATILE (in
the Excel sense, i.e. that it recalculates the function whenever the
spreaddsheet recalculates, even if the cells it depends on haven't
changed). Apparently this can be done with property bindings if the
spreadsheet is on a web page (although since the HOST function is no
longer available, this might not be true any more), and the
Spreadsheet component refers to those functions as "semi-calced". My
problem is that I want to do this with the spreadsheet on a VB form.
Can I do it? I've found an interface called IsAddInClient that has a
method "IsSemiCalced", which looks like what I need, but there is no
documentation for this interface. Can anyone help?
