python - specifying targets for a custom scon builder -


hey i've written custom builder should work differently .c files .structdoc file. here's sconstruct file

env = environment() prepare_structdoc = builder(action='python prep_structdoc.py < $source > $target', suffix='.structdoc', src_suffix='.c') prepare_postc = builder(action='python preprocess_mods.py < $source > $target', suffix='.postc', src_suffix='.structdoc')  env['builders']['structdocbuilder'] = prepare_structdoc env['builders']['postcbuilder'] = prepare_postc sconscript('mods/sconscript', exports='env')

these builders work on 1 source , produce 1 target, run loop in sconscript on *.c files this

import("env") fname in glob("*.c"):     struct_doc= env.structdocbuilder(source=fname)     post_c = env.postcbuilder(source=struct_doc)

this trick. however, use these builders 1 file if mention . i.e. inside mods/ specify scons -u abc.c.

ive tried using command_line_targets follows:

import("env") fname in command_line_targets or glob("*.c"):     struct_doc= env.structdocbuilder(source=fname)     post_c = env.postcbuilder(source=struct_doc)

scons -u mod_dummy.c output gives me is
scons: building targets ...
scons: nothing done `mods/mod_dummy.c'.
scons: done building targets.

it 1 of targets in command_line_targets isnt going inside loop reason. there must way of achieving this.
how modify code work 1 of them ?

you need specify target node, not source node on commandline.

scons -u abc.postc

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!
