It was Delphi code. In C++ it is:


#include <comobj.hpp>

enum ADCPROP_UPDATECRITERIA_ENUM
 { adCriteriaKey = 0,
 adCriteriaAllCols = 1,
 adCriteriaUpdCols = 2,
 adCriteriaTimeStamp = 3
 } ADCPROP_UPDATECRITERIA_ENUM;

If you use C++ Builder 6 you may need to fix its bug with:

namespace System
{
 void __fastcall CheckSafecallResult(HRESULT hr)
 {
  OleCheck(hr);
 }
}

Then:

 ADOQuery1->Active = true;
 ADOQuery1->Recordset->Properties->Item[WideString("Update 
Criteria")]->Value = adCriteriaKey;
