i am using Borland C++Builer 6 with Indy Components.

I want make a copy of TIdMessage and retain the copy even after the original 
obec t gets deleted. I couldn't find copy constructor which could do job for 
me.

Here is the sample code


       TIdMessage *original = new TIdMessage(Owner);
        TIdMessage *copy;
        original->From->Text  = "Nestle netuser <abc@gmail.com>";

        copy = new  TIdMessage(original);
        delete original;
        Sleep(100);

        //After Original Is deleted I want its copy to be present
        ShowMessage(copy->From->Text);
        delete copy;

Like with any other VCL component, there is no direct way to make a copy of
an object from one instance to another.  If you only care about the
published properties, then you can use the Read/WriteComponent() method of
TStream to stream a DFM representation of an object from one instance to
another.  Otherwise, you will just have to copy the desired property values
one at a time in your own code.

There are no copy constructors in any VCL component.  The VCL is written in
Pascal, and Delphi does not use copy constructors.  That is a C++ idiom.
