Scott,

The APIs you want are as follows:

     HCERTSTORE hStore = CertOpenSystemStore(hCryptProv, "CA");     // or
"ROOT"
     PCCERT_CONTEXT pCertContext = NULL;
     char szName[512];

     while (  ( pCertContext = CertEnumCertificatesInStore(hStore,
pCertContext) )  !=  NULL  )
     {
          // Do something with pCertContext.....
          // For example, extract subject details.
          CertNameToStr(
               X509_ASN_ENCODING,
               &pCertContext->pCertInfo->Subject,
               CERT_SIMPLE_NAME_STR,
               szName,
               sizeof(szName) );
     }
     // Should check GetLastError() for possible error....

     CertCloseStore(hStore, CERT_CLOSE_STORE_CHECK_FLAG);

The Cert... functions are all part of the CryptoAPI v2.0 which is available
on the Platform SDK.  This can be found in the MSDN CDs or online at
http://msdn.microsoft.com/developer/sdk/platform.htm.

Patrick Dolan.
