Hello,
I figured out that when calling Locate() using a single key field you should
not create a Variant for the key value but simply pass the value itself
(e.g., TADOTable->Locate( "FieldName", "KeyValue", options ); ). However, I
would like to not have separate methods of calling Locate() depending on the
number of field names. Is there a way to accomplish this?
TIA,
Kim
