asp.net - Convert a webmethod from c# to vb.net -

i did web method below using c#. i'm tryin convert vb.net, i'm missing something. i'm using ajax calling, paginator/sorter table plugin.

[webmethod( enablesession = true )] public static object listapessoas(int jtstartindex = 0, int jtpagesize = 0, string jtsorting = null) { homecoming new { result = "ok", records = persons.tolist(), totalrecordcount = persons.count }; }

first, error in vb - can't leave parameters optional("attribute webmethod cannot applied method optional parameters"):

<webmethod()> _ public function listapessoas(optional byval jtstartindex integer = 0, optional byval jtpagesize integer = 0, optional byval jtsorting string = nothing)

second, don't know how homecoming message "ok" , list of people.

can me help convert vb.net?

seems can't utilize optional parameters webmethods. can utilize overloading. example:

<webmethod()> _ public function listapessoas(jtstartindex integer, jtpagesize integer) <webmethod()> _ public function listapessoas(jtstartindex integer, jtpagesize integer, jtsorting string)

the c# object returned anonymous object. vb syntax is:

return new { .result = "ok", .records = persons.tolist(), .totalrecordcount = persons.count }

asp.net vb.net

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...
