in the help doc
I found that ,
void __fastcall TDBClientTest::ProviderGetData(TObject *Sender,
TCustomClientDataSet *DataSet)

{
  while (!DataSet->Eof)
  {
    TField *pSensitive = DataSet->FieldByName("SensitiveData");
    DataSet->Edit();
    pSensitive->AsString = DoEncrypt(pSensitive->AsString);
    DataSet->Post();
    DataSet->Next();
  }
}

It can encrypt the data, I can suceesfully do that
but in help DOC
__property TRemoteEvent BeforeApplyUpdates
1. The client dataset receives a BeforeApplyUpdates event, where it can
encode custom information into an OleVariant.

How Can I encode custom information into an OleVariant, is there any sample?
I have use over 1 week to try it, but still fail.
Is there any body help me?
