Calendar

bebelino

I'm working on a calendar-program.
I wonder what the best approach would be for storing the begin- and
end date/time for a particular calendaritem.
Right now I have two fields: Startdate and Enddate. Both date/time.
This is giving me terrible headaches when trying to let the user edit
time-part. Let's say startdate is '01/01/2003 22u15'. When I let the
user edit the 22u15 the datepart is set back to 1899 or something.
It's not the first problem I'm countering wit this one. So I begin to
wonder if it's better to store the startdate for instance in two
fields: startdate and starttime. Both of datatype date/time. Has
anyone got experience on this one? What could be the best approach?
thanks,

Since you were so helpful with my date problem....

Are you entering the entire date & time in the same field? '01/01/2003
22u15' in startdate? Or entering the date at one point and the time at
another? If you enter the full string in a general date formatted field,
both should remain as entered.

As you've found out, access date/time fields hold both date and time. When
you enter a time formatted field, a date of Dec 30, 1899 (or thereabouts) is
stored with the time just as 00:00 is stored with date formatted fields. It
is best to store them seperately if you want to enter them independently.

Finally I have solved this problem.

The date and time are being edited seperatly, but still stored
together in one field.
I still wonder why it's better to store them seperately. Because it
seems to me there's more logic in putting the date and time together
in one field.
I hope off course I won't run into other troubles using this approach.

I would just store the date and time together. Access, I think,
stores the value as a double or something, where the integer part is
the date and the fractional part is the time...
