Hi all,
i will appreciate a little help / advice / anything for the
following problem i'm having.
I need to use the xmldatapacketreader to transfer datasets between
free pascal and delphi.
The problem i'm having is that i can't use UniDirectional and
SaveToStream at the same time ( getting
DataBaseError(SUniDirectional) ) and for big datasets the memory
goes .....
So, does anyone have any idea how to use xmldatapacketreader ( which
implies SaveToStream ) and UniDirectional ?
As you can see there is CheckBiDirectional in the begining of
SaveToStream ...
I am not sure, why is there such check (may be that bookmarks are
used and bookmarks are not supported by unidirectional datasets?)
by the way, one of the uses of a unidirectional dataset, is the
sequential manipulation of big datasets. One of those manipulation is
to transform the data while exporting them. So IMHO it will be nice to
undone the invalidation of the SaveToStream method for the
UniDirectional datasets.
May be a feature request ?
I think so also ;-)
-Laco.
