DAO && CDaoRecordset::SetFieldValue
Имам проблем с едитването в DAO, при все, че нямам проблеми с четенето! Ако някой може да ми каже, къде бъркам ще му бъда благодарен!!!
UpdateData(TRUE);
Recordset.Edit(); //отворил съм го по-горе в кода
COleVariant var;
var.vt = VT_INT;
var.intVal = m_Num;
Recordset.SetFieldValue(_T("Field1"),var);
var.vt = VT_BSTR;
var.bstrVal = m_SpecAn.AllocSysString();
Recordset.SetFieldValue(_T("Field2"),var);
var.bstrVal = m_PropType.AllocSysString();
Recordset.SetFieldValue(_T("Field3"),var);
Recordset.Update();
При този код излиза съобщение "Out of memory", още на първата функция SetFieldValue!!!
Somebody help me!!!

sigurno si go chel veche, no ako ne si vij moje da ti svarshi rabota
Note that if you are not creating a UNICODE recordset, you must either use a form of SetFieldValue that does not contain a COleVariant parameter (one of the last two syntax forms), or the COleVariant object must be explicitly declared ANSI. This can be done by using the COleVariant::COleVariant( lpszSrc, vtSrc ) form of constructor with vtSrc set to VT_BSTRT (ANSI) or by using the COleVariant function SetString( lpszSrc, vtSrc ) with vtSrc set to VT_BSTRT.
