c++ - how to write data TINYXML2 on IOS -


my test.xml this:

<?xml version="1.0"?> <!doctype play system "play.dtd">             <data>     <currentlevel>5</currentlevel>     <bestscorelv1>1</bestscorelv1>     <bestscorelv2>2</bestscorelv2> </data> <dict/>

my code here:

std::string fullpath = ccfileutils::sharedfileutils()->fullpathfromrelativepath("text.xml"); tinyxml2::xmldocument doc;  doc.loadfile(fullpath.c_str());  tinyxml2::xmlelement* ele =  doc.firstchildelement("data")->firstchildelement("bestscorelv2")->toelement(); ele->setattribute("value", 10); doc.savefile(fullpath.c_str());  const char* title1 =  doc.firstchildelement("data")->firstchildelement("bestscorelv2")->gettext(); int level1  = atoi(title1); cclog("result is: %d",level1);

but value of bestscorelv2 when output 2. how can change , write data xml?

in tinyxml2 text represented xmltext class child of xmlnode class. xmlnode have methods value() , setvalue() have different meanings different xml nodes. text nodes value() read node's text , setvalue() write it. need code this:

tinyxml2::xmlnode* value = doc.firstchildelement("data")->     firstchildelement("bestscorelv2")->firstchild(); value->setvalue("10");

the first child of bestscorelv2 element xmltext value 2. change value 10 calling setvalue(10).

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!
