Anything in your records that is a reference type cannot be converted to a byte stream
for sending directly.
You should use shortstrings (which are not reference types) or use a class instead of a
record type and implement a SaveToStream, LoadFromStream type functions.
>procedure HandleItSomeHow(Var Rec; Size : Longint);
>Var
> S : String; //make sure its a LONG string
>begin
> SetLength(S,Size);
> Move(rec,@s[1],size);
> StreamStringOverNetwork(s);
>end;
if the record being converted to a bytestream contains strings (long) or
reference types such as TObject references or PChars/Pointers then the resulting
record read in at the other end would be invalid as the referenced information
wasn't sent.
