Some time ago I posted some questions regarding Blobs. It turns out that the field I was trying to access was defined as VarBinary(8000) so I could not use blob stram (as indicated by V. Vassiliev in an earlier response). The advise I was given was to use ADOQuery->Fields->Fields[]->Value OR ADOQuery->Recordset->Fields->Item[]->Value. Fields->Value yields a NULL or "". I tried the Recordset, but it does not seem to be a correct statement. I finally tried char *Buffer. Buffer =(char*) ADOQuery1->Fields->Fields[4]; I get something that looks like it might be a pointer, but can't get any further. Can someone please assist me in getting this data from this field? It is field [4] and is a byte array with the next field [5] defining the length. thanks, kev
