Can anyone tell me why the code below works fine on Windows 98 however
generates an 'Access Violation' error when you try to set the parameter
values running on Windows NT Workstation. Using either 'Value' or
'ParamByName' generates the same AV error:

   m_pStp->Close();

   m_pStp->Parameters->CreateParameter("paramClient", ftString, pdInput,
                                          20, NULL );

   m_pStp->Parameters->CreateParameter("paramPoolno", ftString, pdInput,
                                          20, NULL );

   m_pStp->Parameters->CreateParameter("paramTaxid", ftString, pdInput,
                                          20, NULL );

   m_pStp->Parameters->Items[0]->Value =
       m_pTbl->FieldByName("Client")->AsString;

   m_pStp->Parameters->Items[1]->Value =
       m_pTbl->FieldByName("PoolNo")->AsString;

   m_pStp->Parameters->Items[2]->Value =
       m_pTbl->FieldByName("Taxid")->AsString;


This fails too:

    m_pStp->Parameters->Items[0]->Value = "1234";
    m_pStp->Parameters->Items[1]->Value = "1994ABCD";
    m_pStp->Parameters->Items[2]->Value = "123456789";


Thanx in advance for your help.........
