I am sure this has been covered many times but I can not find what I am looking for and I am sure it is simple.
I am trying to insert into an access database table a date taken from a calendar control or a textbox that the calendar control writes to.
Currently I am getting a "datatype Mismatch" error.
Here is what I'm trying to achieve: The user enters in the textbox a date. It can be:
20.04.2010 or 20/04/2010 or
01Apr2010 or Apr 01 2010...
Any other formats should be forbidden. When the user leaves the textbox then the date should be displayed as 01-Apr-2009. I already tried but I got only when am entering the numbers only like (21-04-2010) but I want to entering the string like apr, jan, nov .
How to check or validate the textbox entered date is in DD/MM/YYYY format?

This one is probably snap for one for you gurus. I have a SQL table that needs to have every previous date accounted for. The user is not required to submit an entry daily, but is allowed to go back and submit when they have extra time to do so. I would like to display the next day from last date recorded in the SQL Table as a session variable, so when they go to the form to submit, the last necessary date is shown and the user knows where they left off.
