' and some other stuff if you need it
Into a

Shashib
Jerry's reply is correct, but (just in case) dont forget you need to issue
an update command to force mapinfo to accept the changed object
so as per jerry's code>>>>>>>
Fetch First from MyTable
MyObj = MyTable.obj
Alter Object MyObj Info OBJ_INFO_SYMBOL, symbol_style
<<<
now issue something like>>>>>
update MyTable set obj = MyObj where rowid = 1 'this is the first record
in the table
and then process the next object in the table etc, if doing a big table this
can be slow and tedious . I have not had chance to look at changing styles
via a update command that uses a 'function', other listers may be able to
help with this, but i am guessing that a slow for next loop is the only
way.
There are several tools on the directionsmag that cover style setting, I
have uploaded an old one of mine with source code included so you can see
how its works at its clunkiest.... ;-)
(its called qik_colourbycolumn.zip)
