 |
|
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?
