Retrieving field names on a form

hi,

 

i have used below code retieve field names form acrobat 5. has worked fine, have upgraded acrobat 9 , same code errors when executing line 'set fields = aformaut.flelds' getting type mismatch error. simple funtion in vb6 retrieves field names , associated types in comma seperated string?

 

does know why code not work in acrobat 9? or there better way achieve same results acrobat 9?

 

thanks

 

public function fieldlist(byval formname string, ofields string, otypes string)
            
    dim aformaut aformautlib.aformapp
    dim fields aformautlib.fields
    dim field aformautlib.field
    dim acroexchavdoc cacroavdoc
    dim bok boolean
                    
    on error goto errorhandler

 

    set acroexchavdoc = createobject("acroexch.avdoc")
                    
    bok = acroexchavdoc.open("c:\iht400.pdf", "")
            
                          
    'if ok opening pdf, can instantiate the
    'forms automation object

 

    if (bok) then               
                      
        set aformaut = createobject("aformaut.app")
                       
             
        set fields = aformaut.fields ' line errors
                                             
                                             
        each field in fields
                          
            if field.isterminal then
                if ofields = "" then
                    ofields = field.name
                    otypes = field.type
                else
                    ofields = ofields + "," + field.name
                    otypes = otypes + "," + field.type
                end if
            end if
                       
        next field

 

        bok = acroexchavdoc.close(true)
       
    end if
  
set acroexchavdoc = nothing
set aformaut = nothing
set field = nothing
  
errorhandler:
    msgbox "fieldlist error: " + err.number + " " + err.description + " " + err.source
