unix - Trying to get first letter from first name in nawk script to html -


why line 17 not working (commented in code)?:

#!/bin/nawk -f  begin {     print "<html>"     print "<body>"     print "  <table border=2>"     print "    <tr>"     print "      <th>name</th>"                   print "      <th>username</th>"                   print "      <th>email</th>"                         print "    </tr>" }  {     print "    <tr>"     print "      <td>" $2 " " $1"</td>"                        print "      <td>"'{substr($1,1,1)}' "</td>"  ###### line 17                      print "      <td>" $3 "</td>"

am allowed put statement in line 17? im trying first letter of first name.

the single quotes in line should removed. quoting allows shell parse substr , not want happen.

also command substr not substr.

print "      <td>"'{substr($1,1,1)}' "</td>"  ###### line 17

change to-:

print "      <td>" substr($1,1,1) "</td>"

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!
