This is a .Net forum, yet you appear to be using the old VB style methods. These are in the compatibility layer, but things are usually much easier if you use the newer 'pure' .Net classes.

The following will give you the last day of the current month stored in newdt variable:

Newdt = new DateTime(Newdt.Year, Newdt.Month, 1).AddMonths(1).AddDays(-1)

Default Hi

Thanks for the reply, I grabbed the code off the interweb and did not know what version it was other than it was not pulling the correct info.
