date input and validate

[jalz]

Hi Guys,

Im creating a database application and working on various data entry cards. one of the things I need to do is validate data entered in certain fields is formatted correctly. One such type of data is dates. What is the most efficient way (also the simplest for a newbie) to have an input mask on a field which can accept a dd/mm/yyyy format? I'm using the DatePicker extension, so 9 times out of 10, dates will be correct, but I need to be aware that a user may type in a date and I need to make sure its in xx/xx/xxxx format. Any help would be much appreciated

Thanks all
Jalz

Hui Jaz,

you could script a "closefield" handler whcih checks the content.
Quick & dirty example:

Code: Select all

on closefield
   put me into tContent

 ## 1. check for correct items
   set itemdel to "/"
   if the num of items of tContent <> 3 then
      answer "Idiot!"
     put empty into me #or any other punishment
     exit closefield
  end if

  ## OK Now check the three items:
   if the num of chars of item 1 of me <> 2 then
    ### Wrong day format, hurt user NOW!
   end if
    ## etc......
end closefield

You get the picture


Best
