(1)In CAPICOM you can use:
 SignedData.Certificates collection and
 SignedData.Signers collection

Note however that for these collections to be valid and available,
the signature verification must be executed first and succeed:
 SignedData.Verify()

(2) In CryptoAPI, you can open a CMS/PKCS #7 Signed or Enveloped message and then get the
certificates by executing:
  CryptMsgOpenToDecode()
  CryptMsgUpdate()
and then
  CryptMsgGetParam() with
with dwParamType = CMSG_CERT_COUNT_PARAM and CMSG_CERT_PARAM
to get all the certificates.
