Locate with Caculated field

Post by ioda » Wed 01 Oct 2008 21:39

I would like to know if is possible to do locate on VirtualTable with Caculated or Lookup Field. Because I always receive this error message :

---------------------------
Project1
---------------------------
Field ****** not found.
---------------------------
OK
---------------------------

Do you have a solution
thank you

TVirtualTable does not create FieldDescs for saving values of calculated and lookup fields, therefore you can't use the Locate method for these fields in VirtualTable.
Use dataset that has linked database table.
