Hi all,

I'm using a windows forms control that is very similar to Excel, but it's
written completely in managed code.

What I need to do is to reference a cell from outside the control. I need to
uniquely identify a cell. I see one approach now - using named ranges. So the
reference to a cell will be composed of a workbook file name and a named
cell. But if a user modify "the name of the named cell" the approach will not
work.

So, I'm wondering how does Excel references a cells, keeping in mind, that
the referenced cell can still be moved and the link should not be broken.

Thanks,
Vitaly

Programmatically you can hide the name, that would prevent most users from
seeing and changing it. Another way would be with a simple cell formula on
an xlVeryHidden sheet, eg =Sheet1!A13. I can't think of any other way to
"track" a cell.

Note with either method, if the row or column containing the referenced cell
is deleted you will get a #REF! error
