Lets just say I am lost!!!!!!!!! VBA to Visual Lisp

[vbcad]

Below is some code I am attempting to translate to visual lisp. We have upgraded to 2010 and would like to get away from the VBA editor and I can see it will eventually just go away. What it does is takes some blocks on two specific layers and changes the arcs and/or splines and changes the lintype to continous. The blocks are all related to project numbers and have 100's of different names. I think I may be on the right track with the selection set but dont know what I need to do next.I have commented out the VBA code.

(defun c:fixhist ()         ;;; Sub ChBlockEntProp()
(vl-load-com);;;Dim objSSet As AcadSelectionSet
(vla-get-acad-object)
(SETQ SS1 (SSGET "x" '((0 . "insert")(-4 . "<or")(8 . "a-hist")(8 . "a-hist-2000")(-4 . "or>"))));;;filtertype(0) = 0
                                                                                           ;;;filterdata(0) = "INSERT"
                                                                                           ;;;filtertype(1) = -4
                                                                                           ;;;filterdata(1) = "<or"
                                                                                           ;;;filtertype(2) = 8
                                                                                           ;;;filterdata(2) = "a-hist"
                                                                                           ;;;filtertype(3) = 8
                                                                                        ;;;filterdata(3) = "a-hist-2000"
                                                                                        ;;;filtertype(4) = -4
                                                                                        ;;;filterdata(4) = "or>"
                                                                ;;;Set objSSet = ThisDrawing.SelectionSets.Add("BlkSet")

I have since been updating the code. It now looks nothing like this. I will post new code if needed. Thanks for any help

I have some new code. The selection set works fine.I changed the layer just to see if my selection set would work.( i dont need to do that) How do I select the arc and/or spline objects within the block definitions and change the lintype? I am a bit lost.

(defun c:fH (/ ssets acadDocument newsset ctr item)
  (vl-load-com)				; load the visual lisp extensions
  
  (setq acadDocument (vla-get-activedocument (vlax-get-acad-object)))
					;retrieve a reference to the documents object
  (setq ssets (vla-get-selectionsets acadDocument))

					;retrieve a reference to the selection sets object
  (setq newsset (vla-add ssets "SS1"))	;add a new selection set
  (setq filter_code (vlax-make-safearray vlax-vbinteger '(0 . 4)))
					;create a 5 element array for the DXF Code
  (setq filter_value (vlax-make-safearray vlax-vbvariant '(0 . 4)))
;;;;create a 5 element array for the values
  (vlax-safearray-fill filter_code '(0 -4 8 8 -4))
;;;;DXF Code for Objects and Layer
  (vlax-safearray-fill
    filter_value
    '("insert" "<OR" "A-Hist" "A-HIST-2000" "OR>")
  )
;;;;the filter values
  (vla-select
    newsset acSelectionSetAll nil nil filter_code filter_value)
;;;;select ALL Blocks on Layers A-hist or a-hist-2000
  (setq ctr 0)				;set the counter to zero
  (repeat (vla-get-count newsset)	;count the number of objects and loop
    (setq item (vla-item newsset ctr))	;retrieve each object
    (setq check (vlax-property-available-p item "LAYER" T))
					;check if the entity has a layer property and can it be updated 
    (if	check				;if it can
      (vlax-put-property item 'LAYER "A-WALL-SLAB") ;change it's layer
    )					; end if
    (setq ctr (1+ ctr))			;increment the counter
  )					;repeat
  (vla-delete (vla-item ssets "SS1"))	;delete the selection set
  (princ)
)					;defun
(princ)
					;if
