asynctask code

  public class transaction extends asynctask<string,void,boolean>     {         private string finalbalance1 = "", price1 = "", pname = "", pnric = "", pclass = "", sno = "";         public transaction(string price1, string pname, string pnric, string pclass, string sno, string finalbalance1)         {             super();             this.finalbalance1 = double.tostring(finalbalance);             this.price1 = double.tostring(sprice);             this.pname = sra.studentname;             this.pnric = sra.studentnric;             this.pclass = sra.studentclass;             this.sno = logger.stallno;         }         @override           protected boolean doinbackground (string...url)           {              boolean = true;              httpclient httpclient = new defaulthttpclient();             httppost httppost = new httppost("http://152.226.152.175/nco/webservice.asmx/insertstudenttransaction");             try             {                 list<namevaluepair> namevaluepairs = new arraylist<namevaluepair>(5);                 namevaluepairs.add(new basicnamevaluepair("nric", pnric));                 namevaluepairs.add(new basicnamevaluepair("name", pname));                 namevaluepairs.add(new basicnamevaluepair("class", pclass));                 namevaluepairs.add(new basicnamevaluepair("stallno", sno));                 namevaluepairs.add(new basicnamevaluepair("amountspent", price1));                 httppost.setentity(new urlencodedformentity(namevaluepairs));                  httpresponse response = httpclient.execute(httppost);                 httpentity entity = response.getentity();                 inputstream in = entity.getcontent();                 bufferedreader reader = new bufferedreader(new inputstreamreader(in, "utf-8"), 8);                 stringbuilder sb = new stringbuilder();                 string line = null;                 while ((line = reader.readline()) != null)                 {                     system.out.println(line);                 }               } catch (clientprotocolexception e) {                   = false;                 } catch (ioexception e) {                   = false;                 }                 return good;               }          protected void onpostexecute (boolean good)           {             if(good == true)             {             httpclient httpclient = new defaulthttpclient();             httppost httppost = new httppost("http://152.226.152.175/nco/webservice.asmx/updateparticulars");             try             {                 list<namevaluepair> namevaluepairs = new arraylist<namevaluepair>(4);                 namevaluepairs.add(new basicnamevaluepair("nric", pnric));                 namevaluepairs.add(new basicnamevaluepair("fixedamount", finalbalance1));                 namevaluepairs.add(new basicnamevaluepair("name", pname));                 namevaluepairs.add(new basicnamevaluepair("class", pclass));                 httppost.setentity(new urlencodedformentity(namevaluepairs));                 httpresponse response = httpclient.execute(httppost);                 httpentity entity = response.getentity();                 inputstream in = entity.getcontent();                 bufferedreader reader = new bufferedreader(new inputstreamreader(in, "utf-8"), 8);                 stringbuilder sb = new stringbuilder();                 string line = null;                 while ((line = reader.readline()) != null)                 {                     system.out.println(line);                 }                } catch (clientprotocolexception e) {                   = false;              }catch (ioexception e) {                   = false;              }             }           }     } }

you should use asynctask instead thread here, using 2 seperate asynctask, can call second task in first one's onpostexecute() method.

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
