Hi!
This is the script you have asked for.Using this script you can display the highway ramp for a particular scale.I have used only the highway ramp as a selection criteria. you can extend the script to select features for multiple criteria( include the highway number....).The other criteria can be obtained from the textboxes or comboboxes in the dialog box).For this you have to add more query strings and search the vtab and change the "seletiontype" to #VTAB_SELTYPE_AND in the "query" request accordingly.
Do contact me for further queries.
The script:
----------------------------------------------
myproject = av.getproject
myview = myproject.FindDoc ("the name of the view")
myftheme = myview.findtheme("name of highway shp file")
mydialog = myproject.finddialog("name of the dialog")
mycombobox = mydialog.findbyname("name of combo box in the dialog")
myselectedhighwayramp = mycombobox.GetSelection
myVtab = myftheme.getftab
mybitmap = myvtab.getselection
mysearchstr = myselectedhighwayramp.asstring
myquerystring = "[highway ramp field] = " + mysearchstr.quote
myVTab.Query (myquerystring, mybitmap, #VTAB_SELTYPE_NEW)
myselestedextent = myftheme.GetSelectedExtent
myView.GetDisplay.SetExtent(myselestedextent)
myScale = 6000
myView.GetDisplay.ZoomToScale(myScale)
----------------------------------------------
With Regards
