java - Is there a way to add the value chosen from all combobox into 1 textfield? -


is there way me add value of combobox choosen 1 textfield? i.e noofbks.

for example, have 2 comboboxes, quantitiescb1 , ebquantitiescb1. quantitiescb1 hardcopies, ebquantitiescb1 ebook

every of code working fine. @ end of program page, have text field stating total number of books.

am able add first actionlistener do

totalnoofbks += currenquantity;

for both actionlistener quantitiescb1 , ebquantitiescb2?

inside ebquantitiescb2 have same above code additional

totalnoofbks += currenquantity; noofbks.settext(totalnoofbks);

below coding working fine.

public class cataloguepanel extends jpanel {         jpanel catalogue = new jpanel(new gridbaglayout());          //batman cost , fields         string value1 = "15";         string ebvalue1 = "12";         final jtextfield result1 = new jtextfield();         final jtextfield ebresult1 = new jtextfield();         //total no. of books field         final jtextfield noofbks = new jtextfield();          final int totalbks;          public cataloguepanel(){         jpanel catalogue = new jpanel(new gridbaglayout());          //combobox batman textfield         jcombobox quantitiescb1 = new jcombobox(quantities1);         quantitiescb1.setpreferredsize(new dimension(125,20));         quantitiescb1.addactionlistener(                 new actionlistener(){                     public void actionperformed(actionevent e){                         jcombobox combo = (jcombobox)e.getsource();                         string currentquantity = (string)combo.getselecteditem();                         int finalvalue1 = integer.valueof(value2);                         int finalvalue2 = integer.valueof(currentquantity);                          string resulttext = string.valueof(finalvalue1*finalvalue2);                         result2.settext("$" + resulttext);                     }                 }                     );                    jcombobox ebquantitiescb1 = new jcombobox(quantities1);         ebquantitiescb1.setpreferredsize(new dimension(125,20));         ebquantitiescb1.addactionlistener(                 new actionlistener(){                     public void actionperformed(actionevent e){                         jcombobox combo = (jcombobox)e.getsource();                         string currentquantity = (string)combo.getselecteditem();                         int finalvalue1 = integer.valueof(ebvalue2);                         int finalvalue2 = integer.valueof(currentquantity);                          string resulttext = string.valueof(finalvalue1*finalvalue2);                         ebresult2.settext("$" + resulttext);                     }                 }                     );     } }

  • add integer or double value directly comboboxmodel

enter image description here

import java.awt.gridlayout; import java.util.vector; import javax.swing.icon; import javax.swing.jcombobox; import javax.swing.jframe; import javax.swing.swingutilities; import javax.swing.uimanager;  public class comboboxintegermodel {      private jcombobox comboboxdouble;     private jcombobox comboboxinteger;     private jcombobox comboboxboolean;     private jcombobox comboboxicon;     private vector<double> doublevector = new vector<double>();     private vector<integer> integervector = new vector<integer>();     private vector<boolean> booleanvector = new vector<boolean>();     private vector<icon> iconvector = new vector<icon>();     private icon icon1 = ((uimanager.geticon("optionpane.erroricon")));     private icon icon2 = (uimanager.geticon("optionpane.informationicon"));     private icon icon3 = (uimanager.geticon("optionpane.warningicon"));     private icon icon4 = (uimanager.geticon("optionpane.questionicon"));      public comboboxintegermodel() {         doublevector.addelement(1.001);         doublevector.addelement(10.00);         doublevector.addelement(0.95);         doublevector.addelement(4.2);         comboboxdouble = new jcombobox(doublevector);         integervector.addelement(1);         integervector.addelement(2);         integervector.addelement(3);         integervector.addelement(4);         comboboxinteger = new jcombobox(integervector);         booleanvector.add(boolean.true);         booleanvector.add(boolean.false);         comboboxboolean = new jcombobox(booleanvector);         iconvector.addelement(icon1);         iconvector.addelement(icon2);         iconvector.addelement(icon3);         iconvector.addelement(icon4);         comboboxicon = new jcombobox(iconvector);         jframe frame = new jframe("");         frame.setlayout(new gridlayout(2,2,5,5));         frame.setdefaultcloseoperation(jframe.exit_on_close);         frame.add(comboboxdouble);         frame.add(comboboxinteger);         frame.add(comboboxboolean);         frame.add(comboboxicon);         frame.setlocationrelativeto(null);         frame.pack();         frame.setvisible(true);     }      public static void main(string[] args) {         swingutilities.invokelater(new runnable() {             @override             public void run() {                 comboboxintegermodel cbmodel = new comboboxintegermodel();             }         });     } }

  • then avoiding parseint jcombobox

  • use jformattedtextfield number formatter, same reason mentioned jcombobox

the documentation of error mentioned in title says if commands out of sync; can't run command now in client code, calling client functions in wrong order. this can happen, example, if using mysql_use_result() , try execute new query before have called mysql_free_result(). can happen if try execute 2 queries return data without calling mysql_use_result() or mysql_store_result() in between. from here: http://dev.mysql.com/doc/refman/5.0/en/commands-out-of-sync.html but in first query not fetching data mysql database, inserting. , in second query getting data database. here code $connection = mysqli_connect("localhost","username","password","tbl_msgs"); if(mysqli_connect_errno($connection)) { die("failed connect mysql: " . mysqli_connect_error()); } $query = "insert users (total_comments, total_views) values ({$total_comments}, {$total_views});"; $query .= "insert msgs (no...

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
