The two most obvious differences between the VB and Delphi code are:

1. The Delphi example uses more code.
2. The VB example requires more visual elements.

Aside from that, this example shows how powerful Delphi's VCL framework is because the visual controls are created on the fly. As you can imagine this is a lot more flexible than the VB example. Also, the event handlers are not hard-wired and can even be changed at runtime because of Delphi's support for delegates.
