android - Pulling images from Web -

-

i'm using following code grab images web. uses gridview , depending on position, picks url array. works loading of images hit or miss. every time start app, different number of images load.

it has issues when changing portrait landscape view, 5 out of 10 images may displayed i'll turn device , lose images. few show though.

any ideas on making more robust?

try {                     urlconnection conn = aurl.openconnection();                     conn.connect();                     inputstream = conn.getinputstream();                     bufferedinputstream bis = new bufferedinputstream(is);                     bitmap bm = bitmapfactory.decodestream(bis);                     bis.close();                     return bm;             } catch (ioexception e) {                     log.d("debugtag", "error...");             }             return null;

one thing read there's known bug decoding bitmaps inputstream, , suggested fix google use flushedinputstream (example in below url):

also, i'd put download code asynctask. here's use mine:

public static bitmap loadimagefromuri(uri uri)     {            url url;         try {             url = uri.tourl();          } catch (malformedurlexception e) {             log.v("url exception", "malformedurlexception");             return null;         }          try         {                        httpurlconnection connection = (httpurlconnection)url.openconnection();             connection.setdoinput(true);             connection.connect();             inputstream input = connection.getinputstream();             return bitmapfactory.decodestream(new flushedinputstream(input));         }         catch (ioexception e)         {             e.printstacktrace();             return null;         }     }

i pass in uri due way i've got rest of code set up, pass in url instead , skip first part. keep download tying ui thread.

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;

c++ - Convert big endian to little endian when reading from a binary file -

-
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()) {...

openssl - Load PKCS#8 binary key into Ruby -

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...
