API Block instances

I have a drawing with a couple block definitions in it. Each definition has
2 or 3 instances in the drawing. I select one instance and run my macro.
When I run this: selType = SelMgr.GetSelectedObjectType2(1), it returns type
93, which is swSelBLOCKDEF, rather than the expected type 87 of
swSelBLOCKINST.

Any thoughts as to why it would see it as the definition, rather than the
selected instance? If that's the way it is, then how do I identify the
particular instance that the user selected? I can get all instances of a
definition, but how will I identify the particular selected one?

Wayne,

swSelBLOCKINST = 93 ' "BLOCKINST"
swSelFTRFOLDER = 94 ' "FTRFOLDER"
swSelSKETCHREGION = 95 ' "SKETCHREGION"
swSelSKETCHCONTOUR = 96 ' "SKETCHCONTOUR"
swSelBLOCKDEF = 99 ' "BLOCKDEF"

This is directly out of the BAS file of 2003. and it is the same in 2004 I
don't have anything older to reference. So according to this it is
returning the block instance not the def and therefor you have no problem.
What version are you running anyway?

How do you know that swSelBLOCKINST = 93? When I count down through
swSelectType_e, I get it as 87.

Ah-ha! Found it! If you open the file swConst.bas file and go to the
swSelectType_e section, then it becomes obvious that my previous method of
manually counting down through what is displayed in the API Help is not only
time consuming, but also inaccurate. Turns out that there are "holes" in
the numbering sequence: that is not all numbers are used.

Actually, I think I knew this some years ago and obviously forgot it. Oh,
well, humble hat is on and back to work.

The object browser is the other way to do this (if you are using the
swconst.dll).
