How can i programmatically select button? Like JOptionPane.showOptionDialog(......,Object initialValue) .

How to put, for example, button on right side of window?
I tried everything..

Solved

Instead of Thread.sleep() i make a thread where i dispose the dialog

Is this ok way?

Hi!

Code is simple something like that:

button.addActionListener(new ActionListener(){ // set label text on dialog Thread.sleep(1000); dispose(); });

When someone click on button i want to change label text and to close dialog after 1 second. This not works because label is refreshed when function is ended.
How to solve this?

I solved this but this is stupid way.
I just sleep client for 100 miliseconds like that:

LoggingThread logging=new LoggingThread(); Thread.sleep(100); // THIS LINE IS ADDED //execute SQL query if(data OK) logging.interupt(); else{ //show error logging.interupt(); }

Whay now works?

Sorry for late answer.

Here is thread:
package dialogs; import java.awt.Dimension; import java.awt.Point; import java.awt.Toolkit; import javax.swing.JDialog; import javax.swing.JLabel; import javax.swing.WindowConstants; import net.miginfocom.swing.MigLayout; public class LoggingThread extends Thread { private Logging logg=null; public LoggingThread(){ start(); } @Override public void interrupt() { super.interrupt(); logg.setVisible(false); logg.dispose(); } @Override public void run() { super.run(); logg=new Logging(); while(true){ try { Thread.sleep(500); logg.updateProgress(); } catch (InterruptedException e) { /* nema potrebe obraditi izuzetak jer je ok ako dodje do ovoga izuzetka ovaj izuzetak se javlja kada Login klasa pozove interupt metodu a ova nit spava. */ } } } } @SuppressWarnings("serial") class Logging extends JDialog{ private JLabel logging=null; private JLabel progress=null; private int dotNum=0; public Logging(){ logging=new JLabel("Logging"); progress=new JLabel(""); setLayout(new MigLayout()); add(logging,"cell 0 0, gaptop 15, gapleft 70"); add(progress,"cell 1 0"); // pozicioniranje na centar ekrana Dimension size=new Dimension(300,100); Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize(); Point location=new Point(screenSize.width/2-size.width/2,screenSize.height/2-size.height/2); setBounds(location.x, location.y, size.width, size.height); setVisible(true); setResizable(false); setTitle("Logging"); setDefaultCloseOperation(WindowConstants.DO_NOTHING_ON_CLOSE); } public void updateProgress(){ if(dotNum<10){ progress.setText(progress.getText()+". "); dotNum++; } else { dotNum=0; progress.setText(""); } } }

Button listener (ActionListener)
LoggingThread logging=new LoggingThread(); //execute SQL query if(data OK) logging.interupt(); else{ //show error logging.interupt(); }

Hi!

I want to run some kind of loading (refreshing text) while programs works in background.
I'm tried with thread but it not works propertly.

This is my algorithm:

1. enter data
2. start loading thread
3a. if data OK stop loading thread and show result
3b. else stop loading thread and return to 1

Thread in run method have infinity loop "while(true)". I stops thread with thread.inrerupt();
Problem is when i enter wrong data second time. When enter data second time thread first stops and then starts! (but first is called start).

I know that threads can do this but how can i solve this?
Thanks!

my bad, contains. Syntax is ok but function not works.

This way works:

char[] caracters=textField.getText().toCharArray(); for(int i=0;i<caracters.length;i++) { if(caracters[i]=='-') { e.consume(); isConsumed=true; break; } }

Why this not works?

if(myString.contain("-"))

How can i get all foreign key columns with theirs mother tables?

For example i have AA foreign column. How to know what table is mother table of this column?

I use DatabaseMetaData interface and i know how to get foreign columns but dont know how to get mother tables

How can i do this?

I write true and false but still nothing. The problem is when i set value to one variable the value is not permanent. Next time when i call function value is false. Why?

var a=false; function test() { a=true; } function test1() { // here value of a=false why? (before this function i called test()) }

No, i didnt say to read, but if you know from experience with commons.

You'r right. I use org.apache.commom.fileupload and multi-part form

Can you tell me how to get parameters i dont have much time to read documentation

When i write System.out.println(request.getParameterMap()) i get "{}".
