I want to exchange Delphi class instances from one Delphi app to another
one
with Drag&Drop...
I thought of using OLE Drag&Drop but it's a bit complicated...

Could I use

serialization and standard copy
+
paste and deserialization

to achieve this?

Does Delphi serialize objects automatically, or do I have to implement
some
Serialize method for every new class I define?

Hello

I keep save post that I think will come in handy. Here are sites that a
suppose to have drag and drop
Also there is a example of drag and drop in the book Delphi Developers
Handbook.

This is from Peter Below (TeamB)

there are some examples for OLE drag&drop at

  ftp://www.melander.dk/anme/delphi/DragDropDemo.zip

As for the serialization there is a way to serialize delphi components it is
something like this.

serialization
var  Stream: TMemoryStream;
       Writer: TWriter;
begin
  Stream := TMemoryStream.Create;
  Writer := TWriter.Create(Stream, 1024)
  Writer.Component(MyObject);

un-serailize
begin
  Reader := TReader.Create(Stream,1024)
 MyObject := Reader.ReadComponent;

You could also look at the DCOM Streaming example in the delphi Informant
magazine.  The code for it can be downloaded from
www.informant.com/delphi/dinewupl.htm File name: DI9803DB.ZIP.  This code
can send a object to another application via com.
