xtext - How to check whether an XFeatureCall actually refers to something -


when i'm scanning ast want check whether element of type xfeaturecall can resolved.

concrete example:

val x = 2 val y = x + z

i know that

val y = <xfeaturecall> + <xfeaturecall>

but xfeaturecall "z" should give true (when applying yet found predicate i'm searching).

so far haven't been able find pattern. except every unresolvable variable satisfies following condition:

fc means xfeaturecall

fc.feature instanceof jvmvoid && !fc.explicitoperationcall

this not enough. because sees "system.out.println"

note: use treeiterator root ast element

if necessary examine how xbasecompiler prefer not :)

the proper check fc.feature.eisproxy check whether feature not resolved. mean 'it sees system.out.println'?

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!
