c++ - Unglobalising a namespaced class without editing the header -


google provide protobuf template messages send ad exchange network. (available freely here) use protoc turn template c++ code (autogenerated). have problem 1 of classes' names clashes 1 defined me, like

#include "realtime-bidding.pb.h"  // g++ complains bidrequest ambiguous. void bidrequest::fromgoogle(const std::string& protobuf) {     // want write:     // google::bidrequest r;     // r.parsefromstring(protobuf);     if (r.has_field())     {         this->field = r.field();     } }

i unable without editing files auto-generated protoc (not we'll have each time .proto file changed), , cannot figure out way through use of namespaces.

what real issue google insist of classes in global namespace, e.g.

// realtime-bidding.pb.h class bidrequest_mobile : public ::google::protobuf::message {     inline ::bidrequest_mobile_deviceosversion* mutable_os_version();`.            ^^ }

so cannot like

namespace google { #include "realtime-bidding.pb.h" }

as it'll stop auto-generated code compiling.

namespacing code mean far many changes very, large codebase, although correct solution. however, am.

is there trick work without editing autogenerated files? there reason why of classes put global namespace?

you can use package in .proto files.

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!
