c++ - Singleton class pointer assignment doesn't work -

i have class abc singleton.(this c++) when

abc *b = abc::getinstance(); abc* a; a=b;

then when check in debugger value of b not assigned a.

in debugger value of shown 0x00000000 , garbage values members of abc (vs 2008 debugger)

i did *b in debugger watch window , see valid values, when *a see null , garbage values (this after above process over)

a , b pointers.

the address point same, although specific address different.

one other reason might you're debugging in release mode, , you're not using variable a afterwards. in case, compiler can decide omit declaration , assignment of a.

c++ singleton

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...
