Please, I need help with this problem.
I have a layer with 5 lines as roads, and all of they with a geocode.
Also, i have a mxd as a map service in a ArcGis Server 9.3.
I need to put the map of the service in a webpage across Esri Javascript, but filtering the roads across a GET or POST variable and highlight this road.

Please....help me !! and sorry for my english.

Christian,

If you put the graphics in an array as you add them to the map, you can get the extent of the graphics using esri.graphicsExtent.

See:

finally I found the way to make it.
But now, i have to draw N objects as Points, Polygon and Polylines all in the same query task.
My problem here is about how can set the extent for the N objects.....like ArcMap do it ?

some one can help me ?
