 |
|
How can I pass the Blob field (BlobField.AsString) to
client by using CDS.DataRequest and Provider's OnDataRequest on
AppSrvr.
Clent
var Data: OleVariant;
Data := CDS.Request(..);
// the length of result string is wrong
// Cutted at first #0
AppSrvr
ProviderOnDataRequest(..): OleVariant;
// read somthing from SQLDataSet having BLOB field
Result := SQLdsBLOB_FIELD.AsString;
// Length is OK
thanks
Sener
