cabal: installing documentation under hsenv -


i have hsenv sandbox project, , can't cabal install install documentation libraries. following:

cabal install --enable-documentation $package

installs package, without generating haddock docs (only license , such copied docs directory). build log contains only:

install-outcome: installok docs-outcome: ok tests-outcome: nottried

i can't useful information out of cabal install, verbose=3. outside of hsenv, works fine. ideas on how fix, or @ least debug this?

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!
