c++ - QT Is a slot launched in a separate thread -


i have done research on topic . thread @ caught interest , wanted summarize understanding , corrected if going wrong on path , wanted know how queuedconnection work.

here understanding followed question. signals can connected manually slots through 2 different ways first way using direct connection , second way queued connection. in case of direct connection if slot method attached signal in same thread slot method called sequentially (as if method) incase slot in different thread signal launched queuedconnection launch when finds appropriate. (now in case not sure if launch new thread or how proceed on doing that)

slots don't belong particular thread, plain functions. objects do. if connect signal slot queuedconnection, signal emission create event , send event queue of target. qt arrange slot called when internally processing event.

as events, processed in thread of object's thread affinity. can change thread calling movetothread on target object.

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!
