Berkeley DB - dbp->get problem ...

I'm trying to use the Berkeley DB library since 2 days now. When I create a DB and add records to it, I can retrieve whatever I want ...

But once I close the database, reopen it and tried to read records from it with the same code, the dbp->get call fails with error 22 which says invalid argument.

Here's my sample code:

      for (loop = 95; 90 < loop; loop--)
      {
         sprintf(strKey, "%07lu", loop);

         key.data = &loop;
         key.size = sizeof(loop);

         data.data = strData;
         data.size = strlen(strData);

         ret = dbp->get(dbp, NULL, &key, &data, 0);
         switch(ret)
         {
            case DB_NOTFOUND:
               printf("Retrieve Error: Record Not Found\n");
               break;

            case DB_RUNRECOVERY:
               break;

            case 0:
               ((char *) data.data)[data.size - 1] = 0;
               printf("Retrieve OK: %s\n", (char *) data.data);
               break;

            default:
               printf("Retrieve Error: %s\n", db_strerror(ret));
               break;
         }
      }

Any idea will help ...
