Poco / zlib: error LNK2019 unresolved external "_gzopen" -


i trying use zlib functions while working poco c++ library. linking zlib library directly not work, because poco links , several duplicates while linking. removed zlib.lib libraries list , used poco version only.

because zlib.h part of poco, compiling works perfectly, linking results in following error

error lnk2019 unresolved external "_gzopen"

so can switch between duplicate , unresolved. can me out?

on windows, defining zlib_dll should force export of native zlib interface. optionally, poco inflatingstream , deflatingstream wrap zlib functionality. word of warning: these std streams derivatives , there may performance penalty.

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!
