regarding to the first problem i posted
i found this code in the Builder help , telling me about using
a class called TADOBlobStream :

int S;

ADOTable1->Edit();
TADOBlobStream *BS = new TADOBlobStream(ADOTable1->Fields->Fields[1],
bmWrite);
try
{
  S = Memo1->GetTextLen() + 1;
  char *P = new char[S];
  Memo1->GetTextBuf(P, S);
  BS->Write(P.c_str(), P.Length());
}
__finally
{
  delete BS;
}

it is found in the explaination of  TADOBlobStream::Write function

i tried to test this code in my programs but it didnt work
i got an error saying
 no similar constructor found ,
any advice ????
