dymamic - Copying dynamic array in C++ -


if have like:

int **arr=new int *[3];

and want make this array double size, need make new array:

int **temp=new int *[6]

and copy arr temp, , copy temp arr.

how this?

you're on right track. need is:

  1. allocate array of size 6 (you did that).

  2. copy 3 elements of pointed arr 6-array.

  3. deallocate memory pointed arr.

  4. point arr 6-array.

for 2, use for loop. 3, use delete[]. 4, use pointer assignment.

i'm giving hints instead of code, it's still work in end. purpose of homework learning, after all.

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!
