objective c - How to create random numbers from 4 to 10 -


how can create random number within range? tried following code didn't accomplish task.

int fromnumber = 10; int tonumber = 30; int randomnumber = (arc4random()%(tonumber-fromnumber))+fromnumber;

there 7 numbers between 4 , 10 inclusive. arc4random_uniform() recommended on arc4random() purpose.

int randomnumber = arc4random_uniform(7) + 4

the more general case arc4random_uniform(upper_bound - lower_bound + 1) + lower_bound.

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!
