reflection - Traverse and find all given type instances within complex object graph -

(using vb.net 4.0) have object graph complex - has properties, arrays , other collections, subclasses own properties , collections, etc. want traverse entire object graph , find instances of particular type t, perform particular operation on these instances. there bulletproof way perform total traversal of object graph? reflection, seems hard task prone error.

i wondering binary serialization, since seems clone object, no matter how complicated, in robust manner. there way modify technique, such instead of serializing instead returns list of references sub-objects of given type t? pure speculation, i'm open feasible solution.

well figured out method, though isn't best. because object's graph pretty nested & complex, decided rely on binary serialization, since in (limited) experience offers thorough & robust graph traversal. downside binary serialization can impact performance significantly, after benchmarking doesn't appear limiting factor particular situation.

basically, have type t implement iserializable, can handle post-serialization adding class:

protected sub new(byval info system.runtime.serialization.serializationinfo, byval context system.runtime.serialization.streamingcontext)

another way (without implementing iserializable) create post-serialized method "ondeserialized" attribute.

anyways, can set info streamingcontext object, used describe operation want performed on type t instances. basically, serialize parent object, find , serialize sub-objects of type t, can coded perform desired task upon deserialization. going forward, deal serialized objects.

obviously, serialization can have complications, , method won't work situations. pretty inelegant performance-wise too. needed hassle-free & thorough object graph traversal there go.

How do I check if an insert was successful with MySQLdb in Python? -

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
