Hi Cindy and everyone,

On the way home I was thinking about this problem. I have two ideas:
1) Make a best guess of the passed value type, e.g write a rouitine like this:

function CheckType
lparameter lcValue && User's input
local lcRetType
* Firstly check, if it's a logical 
if len(lcValue)=3 and inlist(lower(lcValue),'.t.','.f.')
  lcRetType='L'
endif
* Check if it's a date
if empty(lcRetType) and (len(lcValue)=10 or len(lcValue)=12) && Could be date
   if substr(lcValue,3,1)='/' and substr(lcValue,6,1)='/' && (10/12/90)
    * check the rest
   endif
endif
** etc., etc.

2) The second idea is not put textbox at all on the form, instead create several classes (or borrow it from here Files section) like txtNumbers, txtDate, txtDateTime, etc. and then add object in run-time depending on which field type was selected from the combobox to replace.

What do you think?

>>We have a Global Editor form, which allows to globally modify field's contents. The form itself is quite simple, it has combobox with fields and textbox to enter a value to replace with. Now, suppose I choose Numeric field and type 11 in this textbox. How can I check, that this entered value is Numeric and replace my field with this?
