Hello,
i evaluate in this time the IBO components. I will transform
delphi applications from BDE to IBO. With GReplace is it no problem
and the application works (no compiler error).

But i became on runtime this error:

Error: 'Ungültige Typumwandlung'

The point is read stream from blob!

Var
InFile: TBlobStream;
.
.
begin
Query1.open;
InFile := TBlobStream.Create(Query1FILEDATA, bmRead);
.
.
end;

(Query1FILEDATA = BlobField in a IBOQuery)

What can i do?

Regards frank
