I wrote part of a program where, in a ADODataSet, record by record I collect 
a lot of field names and their respective content transferring them into a 
ValueListEditor. Next :
---
ADOTableX->Edit();
TADOBlobStream *BS = new TADOBlobStream TBlobField *) ADOTableXAnalisys, 
bmWrite);
try
{ S = ValueList->Strings->Text.Length() + 1; char *P = new char[S];
   try
   { P = ValueList->Strings->Text.c_str();
      BS->Write(P, S);
   }
   catch(...)
   { delete P; throw; }
   delete P;
 }
 catch(...)
 { delete BS; throw; }
  delete BS;
ADOTableX->Post;  // all those to fill the Access BlobField named Analisys
---
passing to to following record but I have an access exception writing to the 
blob field (not always at the same record)
Can you explain what happen
Thanks Nerio
