Question

I have an array Cdo in the form (j,0)(i,0). There are two exceptions: the addresses (j,0) or (j,0)(0), usually empty, may contain a string with an error message [never both at the same time].

Want to pass through those errors without generating a subscript out of range while also documenting it to the cleaned up array, Breaks (in two dimensions, (j,i)).

For j = 0 to Symbol
    If TypeName(Cdo(j,0)) <> "String" Then
        If TypeName(Cdo(j,0)(0)) <> "String" Then
            For i = 0 to UBound(Cdo(j,0))
                Breaks(j,i) = Cdo(j,0)(i,0)
            Next i
        End if
        Breaks(j,1) = "#N/A"
    End if
    Breaks(j,1) = "#TrancheDef"
Next j

I tried IsEmpty and looking for a string (shown), but they both throw errors when looking somewhere not dimensioned. I can’t change the array as it comes in – how can I test whether a location, e.g. (403)(0)(0) “exists” so to speak?

Alternatively:
I could just check if Cdo(j,0)(i,0) exists – if not, then it should be one of the other two cases. Still revolves around the same fundamental question.

Answer 1

function ItExists(byval j as integer) as boolean

  On Error Resume Next
  if lenb((j,0)(0)) then
  'Nothing
  end if
  ItExists=(err.number=0)
  On Error Goto 0

end function

Something like the above should work. Play with it to make it do what you want.
