[MI-L] MAPBASIC: AlterObject
Hi, How to change symbology of serveral mapinfo objects? The MapBasic AlterObject command lets to modify pen and brush of current (selected) object. How can I use that command to change pen and brush of several objects at once?Maybe there is another method of changing object's symbology? Thanks Tomasz (jazzz_) ___ MapInfo-L mailing list MapInfo-L@lists.directionsmag.com http://www.directionsmag.com/mailman/listinfo/mapinfo-l

You have to loop through the collection and change them one at a time. The "collection" can either be ones you've selected manually or they can be in a table or an SQL selection. ___ MapInfo-L mailing list MapInfo-L@lists.directionsmag.com http://www.directionsmag.com/mailman/listinfo/mapinfo-l
RE: [MI-L] MAPBASIC: AlterObject
There was once the suggestion that you could write a function that returned an object and use SQL Update to update all of the objects. So if you had the function Function AlterPen (o as object, p as pen) as object Alter object o Info OBJ_INFO_PEN, p End function You could then alter the pens of each of the objects in a table with Update mytab set obj=AlterPen (obj, p) I seem to recall trying this several years ago, and that it worked once, but I could never get it to work again.

RE: [MI-L] MAPBASIC: AlterObject
Spencer, I think the problem with your function is that the parameters are send ByRref not ByVal. This shoul dbe the correct structure: Function AlterPen (ByVal o as object, ByVal p as pen) as object Alter object o Info OBJ_INFO_PEN, p End Function Peter Horsbøll Møller GIS Developer, MTM Geographical Information & IT COWI A/S Odensevej 95 DK-5260 Odense S.
