Sample Code:

The following example shows creating an alias for a store handle and incrementing the store's reference count.

HCERTSTORE hSystemStore; // The system store handle.

HCERTSTORE hDuplicateStore; // Handle for a store to be

                       //created
                       // as a duplicate of an open
                       //store.

//-------------------------------------------------------------------

// Open a system store using CertOpenStore.

if(hSystemStore = CertOpenStore(

     CERT_STORE_PROV_SYSTEM, // The system store will be a
                 // virtual store.
     0,              // Encoding type not needed with this PROV.
     NULL,           // Use the default HCRYPTPROV.
     CERT_SYSTEM_STORE_CURRENT_USER,
                 // Set the system store location in the
                 // registry.
     L"MY"))         // Could have used other predefined
                 // system stores
                 // including Trust, CA, or Root.

{

   printf("Opened the MY system store. \n");

}

else

{

   printf( "Could not open the MY system store.\n");
   exit(1);

}

//--------------------------------------------------------------------

// Create a duplicate of the MY store.

if(hDuplicateStore = CertDuplicateStore(hSystemStore))

{

  printf("The MY store is duplicated.\n");

}

else

{

  printf("Duplication of the MY store failed.\n.");
  exit(1);

}

//--------------------------------------------------------------------

// Clean up by closing the store.

if(hSystemStore)

    CertCloseStore(
    hSystemStore,
    CERT_CLOSE_STORE_CHECK_FLAG);

if(hDuplicateStore)

    CertCloseStore(
    hDuplicateStore,
    CERT_CLOSE_STORE_CHECK_FLAG);
