actionscript 3 - Getting swf boolean parameters -

i have swf phone call as

/swfuploader/upload.swf?single=true

then in actionscript 3 read in value. it's not working. here's test code (the first block taken http://blogs.adobe.com/pdehaan/2006/07/using_flashvars_with_actionscr.html ):

var keystr:string; var valuestr:string; var paramobj:object = loaderinfo(this.root.loaderinfo).parameters; (keystr in paramobj) { valuestr = string(paramobj[keystr]); trace(keystr + " = " + valuestr); } var issingle:boolean = this.loaderinfo.parameters.single boolean; var issingle1:boolean = this.loaderinfo.parameters['single'] boolean; var issingle2:boolean = loaderinfo(this.root.loaderinfo).parameters['single'] boolean; var issingle3:boolean = loaderinfo(this.root.loaderinfo).parameters.single boolean; trace(issingle + ", " + issingle1 + ", " + issingle2 + ", " + issingle3);

and frustratingly resulting 2 lines traced:

single = true false, false, false, false

what doing wrong?

in actionscript not empty , not null string casted boolean true.

var singlestr:string = this.loaderinfo.parameters.single; var singlebool:boolean = singlestr == "true";

actionscript-3 actionscript parameters loaderinfo

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...
