.net - Validating xml signature on part of the document using SignedXml -

i using signedxml class validate signature in xml document. signature refers part document.

i able verify signature, how can sure signature signing specific part of document need validate? sign different part of document using same key , signature still valid.

from understand, signedxml automatically verifies signature against part of document that's supposedly signed.

a digital signature verified passing signature value and data/content that's supposedly signed (or hash value of it). means if signature verifies, can sure right part of document signed.

if signs different part of document , you're verifying signature against non-signed part of document, won't positive result. , due construction of xml, signedxml verifies signature against what's suppposedly signed, not against else.

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...
