    How do you test if the Selection Set contains anything nothing

    In particular:

    Dim oEnt As AcadEntity
    For Each oEnt In ThisDrawing.ActiveSelectionSet
    Process (oEnt)
    Next

    I get an error if there is nothing in the active selection set
    I can't do
    ThisDrawing.ActiveSelectionSet.Count
    Because it also causes an error.

    Thanks!

    Hi,

    While stepping through your code hold the cursor over the selection set and
    you will see its current value - or nothing if it holds data. Or do a quick
    view of it.

    You could decide to let the error occur and deal with it by using an "on
    error resume next"
