I get acces violation using ODAC TOraTable.

struct InfoForCombo
{
AnsiString ValueHodn;
AnsiString ListHodn;
};
....

void __fastcall TFilterCombo::NastavTTable(TDataSet *poiTTable)
{
...
PoleInfoCombo = new InfoForCombo[iRozsah];
while (!pTTable->Eof)
{
PoleInfoCombo.ValueHodn = pFieldVal->AsString; AsString;
Items->Add(PoleInfoCombo.ListHodn);
pTTable->Next();
i += 1;
}

}

Function is called with pointer to TOraTable. It has worked perfectly with BDE TTable for years. Error ocure only sometime.

Using ODAC Trial Version, BDS 2006 Architekt Update 1, WinXP SP2.

void __fastcall TFilterCombo::NastavTTable(TDataSet *poiTTable)
{
...
PoleInfoCombo = new InfoForCombo[iRozsah];
TField *const pFieldVal = poiTTable->FieldByName(pValField);

while (!pTTable->Eof)
{
PoleInfoCombo.ValueHodn = pFieldVal->AsString; AsString;
Items->Add(PoleInfoCombo.ListHodn);
pTTable->Next();
i += 1;
}

}

We couldn't reproduce this error using information you have specified. Please send to ODAC support address complete sample that demonstrates this problem and include script to create server objects.

Problem wasn't in ODAC component. Alocation of PoleInfoCombo = new InfoForCombo[iRozsah]; was based on RecordCount. But RecordCount returned only 25 because FaetchAll was false.
