Why not converttoregion(circle) and search with resulting polygon?   Jacques   -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Driver, Greg 9434 Sent: 26 juillet 2006 04:20 To: 'Christophe Brabant'; mapinfo-l@lists.directionsmag.com Subject: RE: [MI-L] SerachInfo, SearchRect and SearchPoint or .....something else ?   Chris,   You could always use the MBR of the circle and then use this in the SearchRect() function.  You can then use SearchInfo() function to return the Table/RowID of objects found within the search area and then test to see if these objects do fall within the radius of circle.   Greg Driver System Administrator Applications Support ICT NOT PROTECTIVELY MARKED -----Original Message----- From: Christophe Brabant [mailto:[EMAIL PROTECTED] Sent: 25 July 2006 15:32 To: mapinfo-l@lists.directionsmag.com Subject: [MI-L] SerachInfo, SearchRect and SearchPoint or .....something else ? Hi   There are at least 4 selection modes on a map :   - by clicking a point (SearchPoint(x,y)) - by selecting a rectangle (SearchRectangle(x1,y1,x2,y2) - by selecting all the objects included into a closed polygon - by selecting a circle with a variable radius : in this case, how to query (by program) the objects included into the circle ? Not with SearchPoint, not with SearchRect, ????????????????   Thank you   Chris Internet communications are not secure and therefore Surrey Police does not accept legal responsibility for the contents of this message.
