hi!
 I am not really good in access at all, however i have a job to use an access database with delphi via ADO.

i was wondering, what exactly do i need in the validation text boks to check that we have typed in a date. and another box for time...

time() is no good... since it prints both time & date...

It's not clear if your using Delphi just to look at the data, or are using Access for the programming.  If your using Access, you'd use the IsDate() function to return a logical to check for a valid date.

If you use Delphi via ADO I suppose, or BDE, in both cases you must DoubleClic the TAdoTable, or Ttable and then right button of the mouse - Add all fields.

Now, if you has the little box with all the fields and the form tha you use to enter the data, select a Date or Time field and in the set the EditMask property for exaple !99/99/0000;1;_ for Date, or !90:00:00;1;_ for time.

Then you select  the fiedl and drag it and drop over the form. thats all.

Best Regards.

Well if you wont to put this mask in Access.
you must select the field and set the properties like this form example.
Format:ShortDate ..... You select your desired format
InputMask:99/99/00;0;_ You have a list to choice

For Time is the Same, and the same properties to set.

Of Course first at all you select your table and the design mode.

Best Regards
Marcos.
