Date Time Picker and empty databases

Hi. I have a date time picker in my program which uses ADO to read from an
Access database. It works perfectly, unless the database is empty (no
records) when opened. When you try to open an empty database, the date time
picker returns error 545. Any attempts to progmatically add new records
after the empty database has been opened returns, or to use the DTP and set
a new date for those added records, "Field not updateable, Bound Property
Name: Value, Field Name: Date Planted"

Any ideas?
Set dtpDate.DataSource = adoRecordSet
dtpDate.DataField = "Date Planted"

That Date-Time Picker is being a little bit funky.

If you go to the Date-Time Picker, and set its Checkbox property to true, that
will allow the bound field to be null. This is what is happening with no
records, or with new records. Otherwise, it is trying to get a date out of a
field that is null, which generates the errors you are seeing.

The user then has to check the box to "activate" the date picker. It ain't the
prettiest thing I've ever seen, but it should work correctly.

why not
1) check the recordset (on that table or query) and if empty ............
report that fact back to the user
or if there are records
2) check for a NULL in that field and if so.............. report that fact
back to the user

In this case the user should be allowed to delete all records, close the
database, and if he wants reopen at a later time and using my program add
more entries.

I think the teacher will doc me marks if I don't allow the database to open
if it's empty.

Yes, I quite like this fix. It may not be perfect, but it does the job
well. Besides I can always progmatically check whether it's Null, and set
the CheckBox value progmatically.
