Hello,
I'm French user of Indesign CS3. Please, be forgiving for my poor English.
'b I've a problem when I try to get the index of a line in a Story.
Dim myindesign As InDesign.Application

Dim maselection As InDesign.Story
    Dim mydocument As InDesign.Document
    Set myindesign = CreateObject("InDesign.Application.CS3")
    Set mydocument = myindesign.ActiveDocument
    Set maselection = myindesign.Selection(1).ParentStory
    myindesign.FindGrepPreferences = idNothingEnum.idNothing
myindesign.ChangeGrepPreferences = idNothingEnum.idNothing
    myindesign.FindGrepPreferences.FindWhat = "(?<=~b)\u{1,2} \d{1,2}" Set result = maselection.FindGrep(False)

If I try to get the line index of the first result like that :
   myline = result(1).lines(1).index
myline is the index of the insertion point of the first characters of the result !
I can understand Vbscript and javascript code.
Thank you for your help.
