Hi, having searched through zope's website at the weekend and gone through the mailinglist archive I did not find stuff regarding the below in FAQs or HOWTOs. The general idea behind zope and the features of it are wonderful. I'm thinking of one application and would like to know: Can you create fields in a zope based database where you force the fields to accept e.g. only letters "M" or "W" or any other other combination of your choice? Can you setup database fields with a format e.g. of "99999/99/9" where all 9s mean numeric input 0-9 and the slashs are always put at their fixed positions by the software when the field is displayed for input? Can you setup database fields with a date format e.g. DD/MM/YYYY or MM/YYYY which *force* the user to input values in that format? Can you output queries of databases in a format you can choose yourself, that the output fields may be incorporated into serial letters to be run by/through text-processing or office systems? Would be fine to get your responses. I appreciate your feedback. Have a nice day Michael -- Michael Schmidt mschmidt@fh-koblenz.de MIRROR OF Ghostscript * X-Windows X11 * DJGPP * and more...
