Ado and OLEDB supports Information in the Fieldcollection of
a Recordset like the following snips:
if (DBFieldInfo->Attributes & adFldMayDefer) dothis...
if (DBFieldInfo->Attributes & adFldUpdatable) etc.
if (DBFieldInfo->Attributes & adFldUnknownUpdatable)
if (DBFieldInfo->Attributes & adFldIsNullable)
if (DBFieldInfo->Attributes & adFldRowID)
if (DBFieldInfo->Attributes & adFldKeyColumn
That would be right to solve the Problems... think so... In
ADO/OLEDB I request this infos and respect them.
