Subject Re: [IBO] IBOQuery.OnFilter: BLOB is always empty
Author Renaud
Hi Helen,

Yes, for few cases I need a none trivial filter on BLOB.
Of course I can encode the BLOB in another way, by coding some more
complicated OnGetText and OnSetText events.

But is there a simple way to know the BLOB in the OnFilter ? Or should I
definitely forget about it ?
