windows - Audio: How to set the level of the default microphone? -

this 1 makes me crazy:

on vista+ computer dedicated sound playing/recording application, need application create sure (default) microphone level pushed max. how that?

i found core sound lib, found how immdevice default microphone. what?

docs lead me think need isimpleaudiovolume interface pointer immdevice, how do that?

note i'm interested in any programmatic way set micro level (whether core sound or else). ideally system-wide, application-wide ok.

tia,

the trick in core audio, recording (aka capture) , rendering devices not considered different (as long don't dive deep of course), opposed former apis such wavexxx there different apis input , output devices.

therefore, full example larry osterman sets speaker volume can modified set microphone volume changing erender ecapture in enumerator phone call returns default device.

thanks larry!

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...
