Button can be clicked only 4 times within 24 hours?

I want to create a JSP page which has one button. Requirement of project is that button can be clicked only four times within 24 hours. After 24 hour it should again allow to click button for max four times. How can I do this? Please help.

Hi,
In our project we implemented the same functionality,
This can be simply achieved by object serialization.
i.e you can store object with two attribute say clickCount , startDate and endDate.
you should have seperate thread which does activate and deactivate operations on button with buttonactivateFlag.
when button is clicked you should check for flag and do accordingly, if active increment clickCount, else dont allow.
Thread part: thread update the endDate attribute in object by constant freqency, if startDate != endDate then next day.
buttonactivateFlag = true;
startDate = endDate = current date;
clickCount = 0;
I hope this will work fine!

Mysql datetime datatype, from that datetime how can i compar only time part

Hello i have database table in mysql, there is Datetime datatype column, from that datetime how can i compare only time part .....??
Thanks in advance...

Note you can't simply just compare time via equality however.
Timestamp resolution is to the second or even milli-second. No user wants to match a time to an exact millisecond.
What they want is something like a match by hour - for example returning the number of transactions that happened from 1pm to 2pm. Even that isn't completely correct because then you need to consider whether 1pm and/or 2pm is inclusive or exclusive. Normally one end will be inclusive and the other exclusive.
So first you need to define what the period is.
Then construct the range.
Then pass the range and, as already mentioned, use specific functions to handle the extraction of the time.

I can't click any links within 2 inches of my toolbar and when I left click in that area it gives me the toolbar options. Why is firefox acting like the top of my webpages is the toolbar ?

I have tried everything that I can think of to fix it from troubleshooting to restoring firefox to defaults. The problem didn't occur until after I changed the toolbar skin with a skin from this site. I can't seem to find a way to change the skin back to it's original form to see if that's the problem. Hopefully you can help me so that I do not have to Reinstall firefox.

This issue is probably caused by the Yahoo! Toolbar.

Suddenly can't click and drag within my playlists

I can drag songs or podcasts to my playlist, but cannot organize them once they are in there. Also, previously I could drag them in a particular order, and achieve the desired result but that is no longer the case. Thanks for your consideration.

TS3453 record button must be clicked multiple times

Record play buttons are getting balky on garageband-(macbook pro) loading GB files fron external HD.
Anyone solved this?

figured it out....it was becuase the layer that had the MC engage on it had keyframes all the way to the end of the timeline.....

Firefox often freezes. Many times, I can't click or type anywhere. The only way to fix it is by clicking restore/maximize button. After click it becomes normal again. How to fix this?

Usually after i typed 2 or 3 characters in the address bar it freezes suddenly. And i can't click or type anything. I click the restore button in the top right and it becomes normal for moment. Then the same problem appears again and i have to click the restore button over and over again.

When you're in Arch, use output redirection
lspci >lspci.out
then boot into Ubuntu or something where you can access the files and the BBS, Of course, don't forget to use a new file for each command output.
The new network config in rc.conf is not that complicated (wired anyway; never used wireless). OTOH I've had issues on two machines where I have to restart the network daemon (rc.d restart network) or rerun netcfg (netcfg eth0) after boot to get connectivity. And I still haven't come to grips with the ip command.

My iPod is showing a white screen. I could not see anything. But I can listen to songs by blindly pressing the play button twice. The battery comes only for an hour.? How do I get the display and longer battery?

Hello Friends,
I've two iPod Nanos (4th gen - 8GB). I'm facing a severe problem with both of them. For both iPods, I tried to do this method Simultaneously press the top button + home (central) button. But of no use.
1. My first iPod is showing a white screen. I could not see anything. But I can listen to songs by blindly pressing the play button twice. The battery comes only for an hour.? How do I get the display and longer battery?
2. My second iPod is facing more severe problem. None of the buttons are working. When I connect it my PC it showing "CONNECTED- eject before disconnecting". But it is not ejecting with all the usual methods. When I manually and physically disconnect it from the PC the same "CONNECTED- eject before disconnecting" is still showing till the battery goes off. After that if i press any button it is showing low battery signal. And when i re-connect it to the PC the same process is repeating. When I tied to restore it to the factory settings I'm getting "Error" report.
(I'm using windows 7)
Friends, Please help me with the above problems. It will be a great help.
Thank You.

Sounds like some hardware issues, meaning you'll want to take or send the iPods in for service or repairs. You can choose to have Apple do an out of warranty exchange for the prices indicated in the link below or find another third party service perhaps even local to your area.

Basics from the manual are restart, reset, restore. Try them.

Purchased a new Apple TV and the remote double clicks each time I press the button. It worked fine during set up and for the first two days. I have since moved it and this problem started. Restarted,reset,unplugged,change remotes, no change.Help please.

Purchased a new Apple TV and the remote double clicks each time I press the button. It worked fine during set up and for the first two days. I have since moved it and this problem started. Restarted,reset,unplugged,changed remotes, no change. Latest software update. This is really annoying. iPhone remote app works just fine. Any suggestions?

That's one of the weird things.. it recognizes it maybe 10% of the time. And usually, only after I do the two-button reset. Problem is.. since it won't charge above 2%, anytime I try to do a restore or anything like that using iTunes, my device shuts off and I lose whatever progress I'd made.
So, an update... after reading through a bunch of similar complaints (there are literally 1000's of them so there's NO WAY this isn't somehow ios7 related, thanks a lot APPLE ) I decided to try a restore in recovery mode. After 3 hours and several disconnections... I ended up having to just set it up as a new iPad, as the restore did nothing. Weirdly though... as I was doing the restore in recovery mode.. I noticed I'd gotten up to a 10% charge.. higher than it's been since September, so after setting it up as a new device, I turned it off and plugged it in using the wall charger. 2 hours later and I was up to 38%. Still not great, as my iPad, before ios7 could've fully charged twice in the amount of time it took for me to now get 28% more of a charge. And that's with a fully cleaned out device.. so that really ***** and I'm now more confused than ever.
But I'm gonna leave it overnight charging and see what I come up with tomorrow. Sadly, when I paid $600 for it in February, I never expected to have to play "wait and see" with it...

Can we perform two actions with one button with two clicks one after other?

Sir,
can we perform two actions with one button with two clicks one after other?
I want that when I click an Add Button first time it add data to the database and when I click again this button it clear the form data to empty fields.
Regards
Tanvir

In code it should be easy.
The following code adds a button called butman with a text "ADD".
It then registers a listener that will be called if the button is clicked.
This listener then calls the runAddData method if you clicked on butman while it contained the "ADD" text and it will call the runClearData method otherwise.
Therefore it will swap the button's functionality between ADD and CLEAR on every click.
final Button butman = new Button("ADD");
butman.setOnAction(new EventHandler<ActionEvent>() {
          @Override
          public void handle(ActionEvent t) {
                    if (butman.getText().equals("ADD")) {
                              butman.setText("CLEAR");
                              runAddData();
                    } else {
                              butman.setText("ADD");
                              runClearData();
                    } // END IF-THEN
          }});I hope this is what you wanted.
Some extra food for thought.
You might want to run the ADD and CLEAR methods in their own threads so that it can run in the back ground, without slowing down your user interface.
I also like to rather reuse one button for multiple functionality in stead of making an application with hundreds of nodes only used rarely with masses of code to show and hide them if needed.

How can I get my time machine to allow me to recover files again? After upgrading to OS X, the time machine still backs up the files; but, I'm not able to navigate within the time machine or select any folders or files for restore.

After upgrading MBA to OS X, the time machine still backs up the files; but, I'm not able to navigate within the time machine or select any folders or files for restore.
I've searched and can not find a solution to the problem that's being encountered.

Yeap that all makes sense now.
Do you only have the current backup showing in the TM display?? Won't it fill in the rest?
Over wireless are you waiting for the indexing to finish.. ??
Previous backup may not show for a couple of hours.
Long short of it.. Mavericks version of TM is a pain.
Sometimes it is easier to completely ignore the TM backup and do the restore manually.
I have posted the details here. See if this helps.

Default button being clicked multiple times when enter key is pressed

Hello,
There seems to be a strange difference in how the default button behaves in JRE 1.4.X versus 1.3.X.
In 1.3.X, when the enter key was pressed, the default button would be "pressed down" when the key was pressed, but wouldn't be fully clicked until the enter key was released. This means that only one event would be fired, even if the enter key was held down for a long time.
In 1.4.X however, if the enter key is pressed and held for more than a second, then the default button is clicked multiple times until the enter key is released.
Consider the following code (which is just a dialog with a button on it):
public class SimpleDialog extends JDialog implements java.awt.event.ActionListener
private JButton jButton1 = new JButton("button");
public SimpleDialog()
this.getContentPane().add(jButton1);
this.getRootPane().setDefaultButton(jButton1);
jButton1.addActionListener(this);
this.pack();
public void actionPerformed(ActionEvent e)
if (e.getSource() == jButton1)
System.out.println("button pressed");
public static void main(String[] args)
new SimpleDialog().show();
When you compile and run this code under 1.3.1, and hold the enter key down for 10 seconds, you will only see one print line statement.
However, if you compile and run this code under 1.4.1, and then hold the enter key down for 10 seconds, you will see about 100 print line statements.
Is this a bug in 1.4.X or was this desired functionality (e.g. was it fixing some other bug)?
Does anyone know how I can make it behave the "old way" (when the default button was only clicked once)?
Thanks in advance if you have any advice.

Hello all,
I think I have found a solution. The behaviour of the how the default button is triggered is contained withing the RootPaneUI. So, if I override the default RootPaneUI used by the UIDefaults with my own RootPaneUI, I can define that behaviour for myself.
Here is my simple dialog with a button and a textfield (when the focus is NOT on the button, and the enter key is pressed, I don't want the actionPerformed method to be called until the enter key is released):
package focustests;
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
import java.util.*;
public class SimpleDialog extends JDialog implements java.awt.event.ActionListener
private JButton jButton1 = new JButton("button");
public SimpleDialog()
this.getContentPane().add(new JTextField("a text field"), BorderLayout.NORTH);
this.getContentPane().add(jButton1, BorderLayout.SOUTH);
this.getRootPane().setDefaultButton(jButton1);
jButton1.addActionListener(this);
this.pack();
public void actionPerformed(ActionEvent e)
if (e.getSource() == jButton1)
System.out.println("button pressed");
public static void main(String[] args)
javax.swing.UIManager.getDefaults().put("RootPaneUI", "focustests.MyRootPaneUI");
new SimpleDialog().show();
and the MyRootPaneUI class controls the behaviour for how the default button is handled:
package focustests;
import javax.swing.*;
* Since we are using the Windows look and feel in our product, we should extend from the
* Windows laf RootPaneUI
public class MyRootPaneUI extends com.sun.java.swing.plaf.windows.WindowsRootPaneUI
private final static MyRootPaneUI myRootPaneUI = new MyRootPaneUI();
public static javax.swing.plaf.ComponentUI createUI(JComponent c) {
return myRootPaneUI;
protected void installKeyboardActions(JRootPane root) {
super.installKeyboardActions(root);
InputMap km = SwingUtilities.getUIInputMap(root,
JComponent.WHEN_IN_FOCUSED_WINDOW);
if (km == null) {
km = new javax.swing.plaf.InputMapUIResource();
SwingUtilities.replaceUIInputMap(root,
JComponent.WHEN_IN_FOCUSED_WINDOW, km);
//when the Enter key is pressed (with no modifiers), trigger a "pressed" event
km.put(KeyStroke.getKeyStroke(java.awt.event.KeyEvent.VK_ENTER,
0, false), "pressed");
//when the Enter key is released (with no modifiers), trigger a "release" event
km.put(KeyStroke.getKeyStroke(java.awt.event.KeyEvent.VK_ENTER,
0, true), "released");
ActionMap am = SwingUtilities.getUIActionMap(root);
if (am == null) {
am = new javax.swing.plaf.ActionMapUIResource();
SwingUtilities.replaceUIActionMap(root, am);
am.put("press", new HoldDefaultButtonAction(root, true));
am.put("release", new HoldDefaultButtonAction(root, false));
* This is a copy of the static nested class DefaultAction which was
* contained in the JRootPane class in Java 1.3.1. Since we are
* using Java 1.4.1, and we don't like the way the new JRE handles
* the default button, we will replace it with the old (1.3.1) way of
* doing things.
static class HoldDefaultButtonAction extends AbstractAction {
JRootPane root;
boolean press;
HoldDefaultButtonAction(JRootPane root, boolean press) {
this.root = root;
this.press = press;
public void actionPerformed(java.awt.event.ActionEvent e) {
JButton owner = root.getDefaultButton();
if (owner != null && SwingUtilities.getRootPane(owner) == root) {
ButtonModel model = owner.getModel();
if (press) {
model.setArmed(true);
model.setPressed(true);
} else {
model.setPressed(false);
public boolean isEnabled() {
JButton owner = root.getDefaultButton();
return (owner != null && owner.getModel().isEnabled());
This seems to work. Does anyone have any comments on this solution?
Tjacobs, I still don't see how adding a key listeners or overriding the processKeyEvent method on my button would help. The button won't receive the key event unless the focus is on the button. There is no method "enableEvents(...)" in the AWTEventMulticaster. Perhaps you have some code examples? Thanks anyway for your help.
