ADO컴포넌트 쓰려고 하는데.. 모르는게 너무 많네요.. ^^

for(int i = 0; i < pNumber; i++)
{
    try
    {
        lpADOConnect[i] = new TADOConnection(Application);
        lpADODataSet[i] = new TADODataSet(Application); // 여기서 에러................

        lpADOConnect[i]->Mode               = cmReadWrite;
        lpADOConnect[i]->ConnectionString   = "................";

        lpADODataSet[i]->Connection         = lpADOConnect[i];
    }
    __finally
    {
    }
}

코드가드로 돌리니깐 최종 에러 지점이 ADODB.hpp의 965번째줄입니다..
inline __fastcall virtual TADODataSet(Classes::TComponent* AOwner) : TCustomADODataSet(AOwner) { }
