Can a macro erase it's self after a set criteria?

[Guest]

I have a spread sheet that I use that has a macro that extracts data from a DB.

This is great for a snap shot but I want to capture this data over time.

Is it possible to set a formula/macro in a cell that would do 1 of three
things

1) tomorrow – do nothing, maintain the formula in the cell
2) today – copy data from a different location or run a formula
3) Yesterday – force the data captured yesterday to stay in the cell as a
value.

I hope that makes sense.

I'd be inclined to have three objects or controls on the s/s, each one
linked to its own macro and which would run one of your options above.

If you want further advice please post back with a few more details.
e.g. what's the formula in the cell (1), what's the cell reference of
the different loacation (2) and what does it contain?

If you want more info I will try to supply,

Basically, I dump a DB into Excel and on a summary page put together a snap
shot of current status on the project. The cells on the summary page
contain formulas that derive a number from the DB. Several countif, dsum,
and aray formulas.

This works great for looking at the data at a monment in time But I would
like to start tracking this over time and generating a trend line.

sure I can go into the sheet and copy and past the values to a time based
table on a different page but I would like to set the page up in the work
book and update it's self via a formula or function.

1) I would like the cells relating to any day in the future to be blank
2) I would like the cells relating to today to update themselves from the
summary sheet as often as I update the sheet.
3) I would like dates in the past to maintian the last value they loaded.

Does that help?

I'm interpreting this to mean that the same cell will contain
different values at any time. In which case I suggest that VBA macros
attached to command buttons or something similar, and the worksheets
change event are what you want, rather than Excel functions.

That said, it would appear that 1 & 2 below could be dynamic functions
using lookups or array functions with conditions, since for 1 you can
generate future dates based on today's date. And today's date can be
derived from the =Now() function. You probably still need a macro for
item 3 since it appears you want to Copy and then
PasteSpecial(xlvalues), and this macro needs to understand what is
meant by past dates i.e. dates earlier than the =Now() function.
