i have syntax error in def atender (x), in def, don't know why, check code , still can't find problem , please :c

the line before missing closing parenthesis:

r1.config(text=("atendiendo a:"+str(a)) #    ----^   --^                ---^ ^^

you have 3 opening parenthesis, closing 2. second opening parenthesis can dropped:

r1.config(text="atendiendo a:" + str(a))

you have same problem few lines down:

r2.config(text=("atendiendo a:"+str(a)) #    ----^   --^                ---^ ^^

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
