Check for zero-length array? 1

[Ed2020]

Hi,

Is it possible, in VB6, to check for a zero length array (i.e., one with no elements)?

TIA,

Ed Metcalfe.

I think that UBound or Lbound shall raise an error number 9 with description of Subscript out of range...

Jerry,

Thanks for your reply.

Is there anyway of checking without relying on trapping an exception?

And a keyword search of this forum would have found a home-grown variant in thread222-836312 which was a later derivative of the earlier thread222-443102

Will it show up as a Nothing object - and if that is the case you can do something like:

if isnothing(myarray) then

or
if not (myarray is nothing) then

No

Greg,

Arrays are not considered objects in VB6 (unlike newer languages such as Java and the .Net languages) so =Nothing doesn't work.
