<p dir="ltr">Hi, </p>
<p dir="ltr">FPC does not support copy-construction so either you must override the TPersistent.Assign method or in case of TComponent you can use ReadComponent/WriteComponent. </p>
<p dir="ltr">You should also take into account deep vs swallow copy semantics as well as the type of the container and contained classes (TPersistent/TCmponent/TCollection descendant).</p>
<p dir="ltr"> For records I am not sure, probably you should need a method on the container or check on some internal (compiler magic) functions such as CopyRecord and others. </p>
<p dir="ltr">Hope that helps.</p>

Oops, I just typed that away and did not hit CTRL-F9 - which is useless<br>
in the mailer anyway. ;)<br>
