Strange error under ce

Question

vs2008, wm6.5, bdb5.2.36
test code:
DB_ENV* env = NULL;
DB* dbp = NULL;
int ret = db_create(&dbp, env, 0);
ret = dbp->open(dbp, NULL, "test.bdb", NULL, DB_HASH, DB_CREATE | DB_TRUNCATE, 0);
the last ret is assigned to 22, reporting "DB->put: method not permitted before handle's open method", but there is no put at all;
under debugger,step into the last line, it directly jump to __db_put_pp. I've also stepped into db_create, but the handle seems be all initialized with correct function address.

Hi,
The sort of error you are seeing is usually due to one of two issues:
1) You are building based on the wrong version of db.h. You should check your project properties to ensure that the correct version of db.h is being included.
2) You are linking to the wrong version of the Berkeley DB dll at runtime. Can you check to see if there are multiple versions of Berkeley DB installed on the WM device?
One further question:
Can you run the wce_tpcb sample application included in the Berkeley DB solution file on your emulator?
