 |
|
I previously played around with a small project using multicast. Under
Indy 9 the read procedure used AData as a Tstream.
procedure TForm1.MCclientIPMCastRead(Sender: TObject;
AData: TStream; ABinding: TIdSocketHandle);
Under Indy 10, It is of a type TBytes. Does somebody have a couple of
lines of code on how to read the data delivered? How do you determine
the size of the received data buffer.
TIA

Actually, it is a TIdBytes. Delphi has a bug in it where the generated
event handler produces the wrong declaration.

There are many BytesTo...() functions in the IdGlobal unit (BytesToString(),
BytesToInteger(), etc) for retreiving various data types from a TIdBytes.

TIdBytes is a dynamic array of bytes, so use Length(). Just like you would
to get the size of a string.
