[Excel 2002 says] Jello again!
(please be patient, there is a question below...)
I'm working on a spreadsheet that's formatted to look like a calendar.
There's a month-name across the top of the sheet (spanning multiple cells);
Weekday names under that, and "days" arranged just like squares you see on a
calendar. Days are always a fixed width (two cells) but each day can hold a
different "list" - the number of rows in each day WILL vary (OK, the days are
really rectangles). It's expected the list in each day will contain 4 to 10
rows.

When the user changes the sheet, it initiaites a lot of input
validation and processing which are very dependent on the date, and row/col
within the date being edited. It seems impractably messy to figure out the
date/row/col from absolute coordinates given that, calendar top/left is
variable, rows/cols between cells is variable, day height (row-count) is
variable, (as user adds rows, can grow, pushing down remaining weeks.) I'm
not saying it's impossible, just impractical.

If not, I could write date/row/col data on a "shadow" sheet. It would
be great if a date/row/col typedef could be cast to/from a string stored in
shadow-sheet:
Q. Is there a way, with VBA, to cast arbitrary data-structures to/from
strings?
Correlary question: Can cells reliably store "binary" strings?

Any help, ideas, constructive criticism is appreciated,
Cheers!
