We store spreadsheets in DB. Now we want to add some extra custom functions. I read your article on how to store/load custom formula to/from file. I guess custom formula will not be saved into DB's blob field within Spreadsheet object either and I need to apply special handling. Is it correct?

Hi Doug,
You can use the approach described in that KB article. To store the resulting file in a BLOB field, just use the TBlobField.LoadFromFile method. When it is necessary to restore the information, call TBlobField.SaveToFile and then, process the resulting file.
Thanks,
Serge
