vla-highlight

After reading 150 posts on google re: vla-highlight, no one has said it
doesn't work, so I know it's me...but...
this works
(defun highlight1 (ent)
(redraw ent 3)
)
this doesn't work
(defun highlight2 (ent / vo)
(setq vo(vlax-ename->vla-object ent))
(vla-highlight vo :vlax-true)
(vla-update vo )
)
this doesn't work
(defun Highlight3(ent / vo)
(setq vo(vlax-ename->vla-object ent))
(vlax-invoke-method vo "HIGHLIGHT" :vlax-true)
(vla-update vo )
)

this doesn't work
(defun Highlight4(ent / vo)
(setq vo(vlax-ename->vla-object ent))
(vlax-invoke-method vo 'highlight :vlax-true)
(vla-update vo )
)
and this doesn't work
Sub testhighlight()
Dim oEnt As AcadEntity
Dim vp As Variant
ThisDrawing.Utility.GetEntity oEnt, vp, "Pick something"
oEnt.Highlight True
oEnt.Update
MsgBox "Did that work?"
oEnt.Highlight False
oEnt.Update
MsgBox "Did that work?"
End Sub

as usual I must be missing something stupidly obvious, any one care to clue
me in?

 

Mark,
Don't believe everything the Help file tries to tell you..... 2, 3 & 4 ALL
work, IF you remove the call to update....

hmmm...
from help file:
"Remarks
Once the highlight flag for an object has been set, a call to the Update or
Regen method is required to view the change. "

guess I should quit reading the help files!

but not with atts in blocks!
(setq ent(car(nentsel"Pick attrib")))
(redraw ent 3 );works
(vla-highlight(vlax-ename->vla-object ent):vlax-true);no workie (even
without update)

 

Hmmm, you are right! And the thread "vla-highlight" started by "Leo" on
11/13/02 has comments from Doug Broad and Luis E. confirming this.....
