Hi!

I think the TIBQuery.Locate method has a pitfall which should be removed.

I tried to pass my desired field values as am array of this type:
VarArrayCreate( [0,2], varOleStr);

I expected that since elsewhere, many things are done via a field's string
representation, that this would work here also. It didn't. I had to use an
array such as this:
VarArrayCreate( [0,2], varVariant);

In the former case there had been no error message, no hint, nothing, it
simply returned false.

Cheers,
Tobias
