Category :Multitier/Remote Datasets
Platform :All
Product :Delphi 3.x
Question:
When I use LoadFromStream on the TClientDataSet,
I receive an EDBClient exception "Mismatch in datapacket".
Answer:
You may not be reseting the position of the stream.
This procedure works...
var
Stream: TMemoryStream;
begin
Stream := TMemoryStream.Create;
try
CDS.SaveToStream(Stream);
// Reset to the beginning of the data packet.
// Forgetting this step is one way to produce the error.
Stream.Position := 0;
CDS.LoadFromStream(Stream);
finally
Stream.Free;
end;
end;
