dear all, i have several problems in mapbasic for which i am looking for a solution. 1. how can i clear a rectangle which a draw in the cosmetic layer? 2. is there a possibility to get the maximal extension of a screen or of a window which must be dependent of the resolution 3. for creating an own tool like overview i always want to update the overview map after the user changed the view (by zooming in or out or panning). how can i start the sub automatically? 4. is there a possibility to read and show the scale of a frame in a layout. thx for your ideas daniel ******************************************** [EMAIL PROTECTED] ******************************************** ---------------------------------------------------------------------- To unsubscribe from this list, send e-mail to [EMAIL PROTECTED] and put "unsubscribe MAPINFO-L" in the message body, or contact [EMAIL PROTECTED]
