[Gabriel Herdt]

Amigos, é Urgente.

Preciso Autenticar comunicação para webservice(soap) via capicom.dll
achei exemplos em sites internacionais. mas não consigo implementar a
rotina.

Aqui vai:

unit main;

(*
Example Delphi SOAP using client side certificates.

According to MSDN you'll need at least IE 5.5.
