saving assembly selection set
hi
could someone give me an example or pointers for working through selected components using vb6 api. i'm having difficulty after the first run through my code as the selection is lost. (i want to work on each selected component in turn)
i grab the count with swselmgr.getselectedobjectcount then get the first selected part with swselmgr.getselectedobjectscomponent2(i) but now i've lost the selection and so cannot just increment (i) anymore.
what is the best method for saving this selection set so i can come back to it ?
thanks

the first thing to do try would be to avoid using code that changes the current selection set. however, that's obviously not possible in every case, and i'm pretty sure not possible in your case since you're posting about it. i think the best thing to do would be to put everything that's currently selected into collections of objects. here's a function i wrote a while back to do just that. it's part of a macro to enable saving and restoring of selection sets. this code was on a form, so a good portion of it can be gotten rid of. if you want to see the entire macro let me know and i can try to post it.
one thing to note - before you try to use any of the objects in the collections, check their issafe property since it's possible that something you did made a face disappear.
note that this code saves faces, edges, vertices, etc. if you really just want all the components that are selected, use getselectedobjectscomponent as you were doing, but put the components into a collection before processing, then iterate through the collection.

i'll get you eh steve, if it's the last thing i dooooo!
sub main()
dim swapp as sldworks.sldworks
dim part as sldworks.modeldoc2
dim selmgr as sldworks.selectionmgr
dim swcomponent() as sldworks.component2
dim i as integer
dim j as integer
set swapp = getobject(, "sldworks.application")
set part = swapp.activedoc
set selmgr = part.selectionmanager
i = selmgr.getselectedobjectcount
redim swcomponent(i)
for j = 0 to i
set swcomponent(j) = selmgr.getselectedobjectscomponent3(j, -1)
next j
part.clearselection
for j = 0 to i
if not swcomponent(j) is nothing then
swcomponent(j).select true
end if
next j
end sub
answer thanks josh and ivana, that's exactly what i needed. not sure why i didn't think of this.
