UDF that returns a date
Hey Pete,
Thanks for the quick reply. If my udf just returns an int, won't Excel just auto format it as a number? Is it even possible to return a value that Excel will recognize and format as a date? ep "Pete_UK" wrote: The UDF should return a number to the cell, which can be formatted as a date to suit your requirements. The number is an integer measuring the number of elapsed days, with 1st Jan 1900 = Day 1. Excel assumes (incorrectly) that 1900 was a leap year, so you need to take this into account. The serial value for today's date (17th Jan 2008) is 39464. Hope this helps.

I know I can't manipulate the cell's NumberFormat from within the UDF, but is there a way to return a value that will be formatted in Excel as a date? It seems any string value I return will default to general. Let me know if any other info would help. thanks |
