To make the code execute locally you should download webmatrix which is an
excellent free downloadable aspx development environment. All you need then
is the following code in a web.config document :
*)
.web

="DelphiProvider" /
/assemblies
="Delphi" extension=".pas" type="Borland.Delphi.DelphiCodeProvider,DelphiProvider" /
/compilers
/compilation
/system
/configuration

and inside a bin directory at the root the DelphiProvider.dll.
You may now create and run asp.net applications with delphi as you chosen
method of codeing.
