Creating a Search Field

[Andre.Bisseret]

Hello Gregory,
If I well understand your aim, you could be interested in adapting the  
search device I programmed thanks to very good advices from Éric  
Chatonnet (as always :-)).
By the way, his tutorial "How to Master Users Data in Entry Boxes"  
might interest you; you can find it on his site :
http://www.sosmartsoftware.com/


I have three fields :
- one is the list to be searched in (say "bigList") -- this field  
could have its visible property set to false
- a second is a one line field where the user write what he/she is  
searching for (say "entry")
- the third is a field where the results of the search appears (say,  
"results")

the script of the  field "entry" is as follow :

local mySubList,
---------------------

ON rawkeyUp
    find empty
     REPEAT
       find fld "entry" in fld "bigList" of this cd
       IF the result is "not found" THEN exit repeat
       ELSE
       put value(the foundline) & cr after mySubList
       END IF
     END repeat
     put empty into fld "results"
     put mySubList into fld "results"
     select char 2 to -1 of line 1 of fld "results"
     select after fld "entry"
     put empty into mySubList
END rawkeyUp

ON returnInField
-- here do what you want with the found word
(I use the found word to find a corresponding card in another stack)
END returnInField

Best regards from Grenoble
