Need some quick and easy code to validate a date range

I have two text boxes on a form that a user enters dates in.

t_start_date
t_end_date

I would like some code to check that the range entered is valid.  In other words, that then t_end_date does not occur before the t_start_date.

1/1/2011  and 12/31/2011  - Good

1/1/2011 and 12/31/2010  - no good

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Something like:
If FormatDateTime(DATE1, vbShortDate) < FormatDateTime(DATE2, vbShortDate) = True Then
MsgBox ("Please enter a valid date.")
txtDate.SetFocus

Above code works only for year and day (not month),
try code below:

If DateDiff("s", Date1, Date2) < 0 Then
'Date1 is later than Date2
Else
'Date2 is later than Date1
End If
