I remember that VFX has a user-defined property to distinguish this case. In other words, the programmer has to set this property in each individual case.
I don't know whether there is an automatic way to determine this.
>I've been looking for a VFP function or a UDF that will allow me to determine if an object's control source refers to either a column in a cursor/table or to a memory variable. If it refers to a column I need to do a REPLACE command to update the column. If it refers to a memory variable I need to replace the value in the variable. Something like this is what I'm looking for:
>
> IF OBJTYPE(Object.ControlSource) = 'C'
> REPLACE (Object.ControlSource) WITH ltNewDateTime
> ELSE
> STORE ltNewDateTime TO (Object.ControlSource)
> ENDIF
