JTextField and Actionlistner problem

Hi ALL
I have a JTextfiled and i added and actionlistner that prints out a word if it is equal to what i tell the textfield to get, when enter is pressed. in my example below it only works if i only put the word "open" into the textfield. however if i write a sentence e.g. " you mus open the door" it does not work. it does not print open.
Does anyone have an idea how i can find and print keywords in a sentence?, if so i will really appreciate it. even if it is possible with JTextArea
Thank you
public void actionPerformed(ActionEvent ae) {
if (jtf.getText().equals("open"))
System.out.println("open");
}

}in your example equals() look for exact match of the key word you supplied. and also its case sensitive.
you better use
if (jtf.getText().contains("open"))this will look for the key word existance in the entire string.
alternatly you can go for regx (regular expressions) search.
but i think in your casse the first one will work.

About JtextField and JButton problem

hi, I dont know how to make this, hope to get help:)
I wanna like this:
A JtextField object -- for user to input some Integer
A JButton -- when users click the button, the content in JtextFiled will be delivered to a variable (say, int a, sent to this "a")in my program.
Here, We dont need to check the content if it is Integer or not for simple.
Any idea for me? thanks!

Write a listener class that implements listener interface. in that class implement the actionPerformed method of the super interface as u need.( I.e assign the value to the variable). Then bind this class with ur button using addActionListener() method( look in API).
ex:
bottonName.addActionListener( new ActionListener()
          public void actionPerformed(ActionEvent e)
               var = textarea.val;
     });

JTextfield and JButton

Hi all
My problem is that i have a JTextfield that is connected to a Oracle database that allow the user to enter data in the database. I want to have a button that will allow the user to test to see whether the data entered in the textfield is valid.
I'm not sure if i need to use sqlj or not. Any help would be gladly received.
Thanks

Hmmm... lots and lots of ways to handle this, depending on your particular need for the particular type of 'validation'. ( More info? )
"JTextField" is not connected to a database in the same way that the infoswing "TextFieldControl" is.. .therefore one could trap the event ActionPerformed off the JTextField and do the checks ( or use the jbutton like you suggest..but it would seem like you'd always want it checked and corrected before continuing towards the inevitable commit attempt??? ).
You can use sqlj, or you can not use it... depends upon the way you've architected your application/environment and your needs and desires.
Note (if you haven't already ) that you can also do a heck of a lot of validation at the entity/view object level.
In my case ( an application ) I have a jdbc connection up at the front end for all my miscellaneous stuff, and a validate PL/SQL stored function. The nice things about using stored procedures/functions are that the validate routines can be nested for quick and easy use by triggers and stored procedures. If you put it outside the database it gets more fun should you want to get at the common validation routines from all approaches.
Curious as to how other folk are architecting their validations....

JtextField and list of data

Hi everyone (and sorry for my english language....).
I've this problem:
I've a Frame with a JtextField and a button. When I click on this button, I want to show a list of data from a database and then I must choose a value that must go to the JtextField.
Have you an idea how I can implement this? Sorry for this generic question, but I don't know how to do..
Thank you!

As to your question.
I've a Frame with a JtextField and a button. When I click on this button, I want to show a list of data from a database and then I must choose a value that must go to the JtextField.
Have you an idea how I can implement this? ..Sure, plenty of people. But they will want to know exactly what you are having trouble with. E.G.
- Getting data from a DB.
- Putting data into a JList.
- Adding listeners to that JList so that choices are acted on, rather than simply high-lighted as the selection.
- Using the event provided to the listener, to update the JTextField.
- Adding a JTextField and JList to a JFrame using layout managers.
If your answer is 'all of that', then I suspect they would be tempted to:
a) Advise you to put this project aside until you have considerably more experience.
b) Refer you to the [Java Tutorial|http://java.sun.com/docs/books/tutorial/].

JTextField and JTextArea don't get focus occuasionally

I am developing a Java Swing Applet. At edit mode, JComboBox, JCheckBox, JRadioBox, and JButton work fine, but JTextField and JTextArea can't get focus occuasionally while I click them.
Anyone has idea?
Thanks

Thank you Himanshu,
but that's not exactly what my issue is. This link describes the undesired effect of ending up outisde of the player window and in the browser.
My problem is kind of the opposite. When I launch the page in the html file I cannot use the tab key to get to any of the controls in the captivate window. I'm stuck in the browser unless I click on the captivate window. That is not acceptable if we want it accessible without using a mouse. I found a way to make it work for chrome like I stated above, but not in FF. Do you have any ideas for this?
Thanks!

JTextField and transparency

I have a JTextField and I am trying to set it up so it is somewhat transparent.
mTextField.setBackground(new Color(255,255,255,50));
But what happens when i do that is this: the textfield as a text value gets the text that i have set up for one of the neighbouring components.
I am not sure why this happens.
Has anyone experienced this problem before? Is there a fix to it?
I tried setting up the text using setText to an empty string but it happens agian. I dont have this problem when the transparency is Not set.
Cheers
Dan

I am not sure why this happens. An opaque component is responsible for painting the entire area of the component, which basically means that the RepaintManager doesnt' have to worry about the garbage that may exist where the component is about to be repainted.
Since you background is somewhat transparent, you can see the garbage left behind. (Don't ask me what its left behind from, thats in the details of the Swing repaint manager which I know nothing about).
Michaels suggestion makes the component transparent which means Swing will paint the background of the components parent. However when you do this, the background of your component isn't painted.
So heres a solution that paints the background of the parent and the child:
JTextField textField = new JTextField("Some Text")
     protected void paintComponent(Graphics g)
          g.setColor( getBackground() );
          g.fillRect(0, 0, getSize().width, getSize().height);
          super.paintComponent( g );
textField.setBackground(new Color(0, 255, 255, 50));
textField.setOpaque( false );

I am not able to launch FF everytime i tr to open it, it says FF has to submit a crash report, i even tried doing that and the report was submitted too, but stiil FF did not start, and the problem still persists, please help me solve this issue in English

'''(in English)'''

Hi Danny,
Per my understanding that you can't get the expect result by using the expression "=Count(Fields!TICKET_STATUS.Value=4) " to count the the TICKET_STATUS which value is 4, the result will returns the count of all the TICKET_STATUS values(206)
but not 180, right?
I have tested on my local environment and can reproduce the issue, the issue caused by you are using the count() function in the incorrect way, please modify the expression as below and have a test:
=COUNT(IIF(Fields!TICKET_STATUS.Value=4 ,1,Nothing))
or
=SUM(IIF(Fields!TICKET_STATUS=4,1,0))
If you still have any problem, please feel free to ask.

BOSD, Battery issues and Heating problem after iOS 8 upgrade

i have upgraded my iPad mini to iOS 8. Ever since I upgraded to iOS 8 am facing blue screen issues and heating problem as well. This is really frustrating even the patch iOS 8.0.2 dint solve the problem. Are you guys listening our complaints. When will you fixing it.

The same thing happened to me on my 2012 Subaru Outback. I'm not sure this will help you since you have a Honda, but I'm posting this just in case.
I paired the audio on my car with my iPhone 6. However, when I turned the car off and back on again, the iPhone would not pair automatically. I had to manually connect the iPhone with the car. Turns out there are two separate bluetooth pairings on my car: one for phone which allows up to 5 devices and one for audio which allows only one device. So I did the second bluetooth pairing for the phone (had already done the audio), and that fixed it. YMMV

          System.out.println("rockCrabs health: " + instance1.health);
}when the code is run it says something like this:
you hit 1
RockCrabs health is 9
RockCrab hit 7
your health is 38
you hit 1
RockCrabs health is 8
RockCrab hit 7
your health is 31
you hit 1
RockCrabs health is 7
RockCrab hit 7
your health is 24
you hit 1
RockCrabs health is 6
RockCrab hit 7
your health is 17
my point is whatever some one hits it always repeats that
my expected output would have to be something like
you hit 1
RockCrabs health is 9
RockCrab hit 9
your health is 37
you hit 3
RockCrabs health is 6
RockCrab hit 4
your health is 33
you hit 2
RockCrabs health is 4
RockCrab hit 7
your health is 26
you hit 3
RockCrabs health is 1
RockCrab hit 6
your health is 20

Remote and IR Problem

A rather odd and annoying problem has recently been occuring on my MBP. A couple days ago my remote (after working without fail for over a year now) suddenly stopped working. Yesterday night and this morning it started working again but after a while it stopped again. I've read dozens of support articles which haven't really helped because there seems to be another problem.
Most articles have stated that there is an option to disable the IR receiver in the "security" window under system preferences. When the IR and remote are not working this option disappears but when they are working the option is present. I have also tried replacing the battery without any result.
I am now thinking that it might have something to do with heat buildup because it is mainly occuring after the laptop has been on for about a half hour, so I am going to try to borrow someone's fan.
If anyone has any suggestions to solve this I would appreciate it if you could help. Thanks!

LG Ally text message and gps problems

hello. ive been with verizon for about 10 years maybe. ive been overall happy with the service and customer service. but the prices should be alot lower.lol. i started out with the motorolas then switched to the lg phones. only problem with the motorola was the speakers. not loud enough. could never hear the phone ring. the lgs usually suffer from the same problem.
i had a few phone problems but nothing like this lg ally. im on my second one and about to be my 3rd one in about 3 months. 1st phone i had every problem under the sun. this phone i am suffering from text message problems and gps problems. i suffer from what everyone else has problems with. the messages wont send. they will eventually lock up. it will show the envelope with the red explanation point ( i think thats the graphic). then usually everytime when i sent a text the texts will close. it will send then bounce back and show up as a draft and i have to resend it and wait for it to go thru. finally the last problem with the texts. when i send a text a phone number from my contacts shows up and freezes on the screen. its in white text with a black background. its the same number every time. it stays on the screen until i restart or pull my battery out.
gps. when i open up google gps that comes with the phone i make sure the gps is on... when the directions are found and the map pops up 9 out of 10 times it just keeps saying searching for gps. the turn by turn never is found. the 1 time it does it takes a good 10 minutes to be found. atleast on my first one ally the gps did work 8 out of 10 times. it just took a good 5-10 minutes for gps to be found and show turn by turn.
anyone else have these problems? where you able to fix them or did you need to get a new phone? the 2.1 update was supposed to fix problems. i think they just made it worse. the ally is supposed to have 2.2 froyo. where is it. is it ever going to get it. i got this phone because i like the lgs and the keyboard. also the sales representative on the phone was giving the lg ally rave reviews. why couldnt he say dont buy this go with a motorola droid. this phone is the biggest junk ever made

I do apologize you are having trouble with your device I looked in our information system on the LG Ally in reguards to issues you are having it states if you have the Free Droid Security anti virus protection application down loaded it will cause the phone to lock up or freeze. Check and make sure you do not have the application on your device. Check you GPS settings and make sure correct. Go to Settings; Location & Security; make sure GPS is on wireless network. If this does not fix issue you can try doing a Master Reset on your device. Make sure your contacts are saved in your G-mail account or through Back Up Assistance.
Master Reset/Soft Reset:
Factory Reset option 1
From the main screen, touch menu tab
Touch Settings
Touch Privacy
Touch Factory Data reset
Touch Reset Phone
Warning: This will erase all data from your phone, including:
Your Google account
System and application data and settings
Downloaded Applications
It will not erase: Current System software and bundled applications; SD Card files, such as music or Photos
Factory Reset option 2 - Warning this will reset device back to original factory settings.
Turn off the phone
Press and hold "home" + "end" + "volume up or down" keys together for a few seconds when the device is power off
Once device displays boot information, release keys.
Soft Reset
Press the Power key.
Touch Power off.
Touch OK.
Press the Power key to power on the device.
or
Remove battery cover, remove battery and reinstall.Also there is a new update for LG Ally it will be the Froyo 2.2 but there is not release date available at this time it will post on your device when available. Hope this Helps. Leslie

}thanks again,

the reason why you can't get the text is because you are reading the value before some actually inserts anything in any fields.
Here is what you need to do:
Create a JDialog/JFrame. Create a JPanel and set that panel as contentPane (dialog.setContentPane(panel)). Insert all the components, ie JLabels and JTextFields. Add two buttons, Login and Cancel to the panel as well. Now get the username and password field values using getText() inside the ActionListener of the Login.
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class LoginDialog extends JDialog
String username, password;
public LoginDialog( ){
    setTitle( "Login" );
    JPanel content = new JPanel(new GridLayout(0, 2) ); // as many rows, but only 2 columns.
    content.add( new JLabel( "User Name" ) );
    final JTextField nameField = new JTextField( "" );
    content.add( nameField );
    content.add( new JLabel( "Password" ) );
    final JTextField passField = new JTextField( "" );
    content.add( passField );
    JButton login = new JButton( "Login" );
    login.addActionListener( new ActionListener(){
      public void actionPerformed( ActionEvent ae ){
        username = nameField.getText();
        password = passField.getText();
        // call a method or write the code to verify the username and login here...
    content.add( login );
    JButton cancel = new JButton( "Cancel" );
    cancel.addActionListener( new ActionListener( ){
      public void actionPerformed( ActionEvent ae ){
        dispose(); // close the window or write any code that you want here.
    content.add( cancel );
    pack( ); // pack everything in the dialog for display.
    show(); // show the dialog.

How do I fix my ipod classic that says very low batter after I have charged it and the problem persists?

I have an Ipod video 30g that says Please wait very low battery. I charged it for about a day and the problem persists. I've tried using some solutions on the internet and none of them worked including: holding the menu and select, holding select and play to put it in disk mode with no avail. Is there anyone who can help me!!!

Have you read this post written by another forum member?
The Sad iPod icon.
However, as your iPod was purchased on Boxing Day, why not get it serviced under the warranty?
You can arrange online service here.
Service request.
Or if an Apple store is near you, take it there and have them check your iPod.
You can make an appointment by using this link.

It's so annoying!! I have created a new Apple ID but after I click verify it just goes back to the previous page!!! It''s really frustrating I have tried for more than 4H, and the problem is not about the apple ID. I can download apps with the apple ID, which means IMessage is the problem! I restarted my iPad, I logged in and out of the apple ID in the store, AND YET IT STILL WON'T WORK, PLEASE HELP!

Hi Vmanfromusa!
It sounds like you are having an issue with activating your iMessage app on your iPad. An article outlining some troubleshooting steps for this issue can be found here:
