Mkdir() permission denied C/linux programming -


when execute code, error couldn't create backup sub-directory: permission denied can't understand why since give full permisions , i'm using admin account on ubuntu.

umask(0777); int folder_date_status = mkdir(filepath_w, 0777);  if(folder_date_status == -1){     perror("couldn't create backup sub-directory");         return -1;     }

an admin account doesn't run full privileges default. programs run don't unexpectedly act privileged users (ie. must explicitly give permission).

to give permission program create sub-directory in directory requires privileged access, try using sudo.

if program name called myprogram, try running:

sudo ./myprogram

then type password if requested.

note super-user access should required if trying make subdirectory in write-restricted directory (eg. restricted directory owned root, or user). ensure parent directory exists (otherwise throw error).

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!
