To extend c-treeDB support to VCL the ctdbCompareRecord() function was added to the TCtRecord class.
TCtRecord.CompareRecords( TCtRecord )
This method compares the current CTRecord content against the argument record.
TctRecord.CompareRecords() returns CTDBRET_DIFFERENT (4086) when records do not match, else CTDBRET_OK.
Example
// MyTableRec is an extra TCtRecord pointer
void __fastcall TFileIOBase::SaveRecordState(void)
{
MyTableRec2 = MyTable->ActiveRecord->Duplicate();
}
bool __fastcall TFileIOBase::IsRecordAltered(void)
{
MyTable->ActiveRecord->Read(); // re-read current record
if(MyTable->ActiveRecord->CompareRecords(MyTableRec2) == CTDBRET_OK)
{return false;}
else {return true;}
}
