ios4 - problem in displaying JSON data in table view on iphone -

-

i can parse data , see output not able display them in table view

problem 1st tableviews code executing rest functions working that's why getting 0 , how avoid ??

this code

- (nsinteger)tableview:(uitableview *)tableview numberofrowsinsection:(nsinteger)section {        nslog(@" value %d",[jsonarray count]);// 0     return  [jsonarray count];   }

in method getting 0 valuee

- (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath    *)indexpath {  nsdictionary *atweet = [jsonarray objectatindex:[indexpath      row]];     nslog(@ " divy      %@",atweet);// nothing        }

other codes

- (void)connectiondidfinishloading:(nsurlconnection *)connection {           [connection release];      nsstring *responsestring = [[nsstring alloc] initwithdata:responsedata encoding:nsutf8stringencoding];     [responsedata release];      nserror *error;     sbjson *json = [[sbjson new] autorelease];   nsdictionary *data = (nsdictionary *) [json objectwithstring:responsestring error:nil];           nsdictionary *menu = (nsdictionary *) [data objectforkey:@"name"];       //label.text=[dict objectforkey:@"firstname"];         // parsing items in nsarray       nsarray *items = (nsarray *) [menu objectforkey:@"phonenumber"];              int ndx;     //nsdictionary *stream;     (ndx = 0; ndx< items.count; ndx++) {              stream = (nsdictionary *)[items objectatindex:ndx];           nslog(@"this title of stream: %@", [stream valueforkey:@"type"]);          [jsonarray addobject:stream];       }         nslog(@" aray %@",jsonarray);// show data working     nslog(@" sterab %@",[stream valueforkey:@"home"]);// working

and view did load()

- (void)viewdidload {             jsonarray= [[nsmutablearray alloc] init] ;         [super viewdidload];      responsedata = [[nsmutabledata data] retain];            nsurlrequest *request = [nsurlrequest requestwithurl:[nsurl urlwithstring:@"http://json/number.json"]];     [[nsurlconnection alloc] initwithrequest:request delegate:self];             }  - (void)connection:(nsurlconnection *)connection didreceiveresponse:(nsurlresponse *)response {     [responsedata setlength:0]; }  - (void)connection:(nsurlconnection *)connection didreceivedata:(nsdata *)data {     [responsedata appenddata:data]; }  - (void)connection:(nsurlconnection *)connection didfailwitherror:(nserror *)error {     label.text = [nsstring stringwithformat:@"connection failed: %@", [error description]]; }

possibly, problem data doesn't load immediately. , uitableview, when created, stores necessary data in sort of cache. allows avoid calls of data source's methods, tableview:numberofrowsinsection: , others. should explicitly call uitableview's reloaddata method refresh table.

to solve problem, should this:

  1. in viewdidload show spinner indicate program activity.
  2. in connectiondidfinishloading: after data initialized, call [yourtableview reloaddata].

C#: Application without a window or taskbar item (background app) that can still use Console.WriteLine() -

-
i'm trying create application adheres following: no taskbar no console or form window can utilize console.writeline() . (i.e. if executes app command prompt write console.) the problem if create windows form (or wpf) application can have there no taskbar, console or window show up, console.writeline() nothing. if create console app, writes console, can't figure out how hide (and if did hide it, write command prompt window?)... how do this? just create standard console application. callers responsibility hide window caused program (from how run c# console application console hidden ): system.diagnostics.processstartinfo start = new system.diagnostics.processstartinfo(); start.filename = dir + @"\myprocesstostart.exe"; start.windowstyle = system.diagnostics.processwindowstyle.hidden;

this question has answer here: how convert between big-endian , little-endian values in c++? 28 answers i've been looking around how convert big-endian little-endians. didn't find solve problem. seem there's many way can conversion. anyway following code works ok in big-endian system. how should write conversion function work on little-endian system well? this homework, since systems @ school running big-endian system. it's got curious , wanted make work on home computer also #include <iostream> #include <fstream> using namespace std; int main() { ifstream file; file.open("file.bin", ios::in | ios::binary); if(!file) cerr << "not able read" << endl; else { cout << "opened" << endl; int i_var; double d_var; while(!file.eof()) {...

i'm trying load particular private key encoded in binary der format ( pkcs#8 ) ruby. however, openssl::pkey won't recognize it. can make work doing console work , transforming pem so: openssl pkcs8 -inform der -in file.key -passin pass:xxxxxxxx >private_key.pem after this, key can correctly read. however, since whole process done in memory instead of writing , reading files. so question is: possible load private keys binary encoded der format ruby/openssl? thank time, fernando yes, can indirectly load pkcs#8 der-encoded private keys using ruby openssl. openssl::pkey::rsa.new handle pem-formatted pkcs#8, easy read binary der , convert pem-formatted string , load string. for example, these der-encoded private keys: $ openssl genrsa | openssl pkcs8 -topk8 -outform der \ -nocrypt -out pkcs8.key $ openssl genrsa | openssl pkcs8 -topk8 -outform der \ -v2 des3 -passout pass:secret -out pkcs8_des3.key you can this: require 'open...
