Help? How to dispose frame from JList Command

To every one out there,
i design an application with a menu using Jlist, when i selected a element from the list, it bring me to the next frame,however this frame with the JList that i want to dispose is still there.
I have try this.dispose();
this.show(false);
this.hide();
and it give a compliation error or unable to run or not function as i expected.
i call the frame using
Frame1 obj = new Frame();
obj.show(true);

Here is my codes
String[] select={"Register new Disc","Delete disc","Edit disc",
"Set Rental Price and duration","View and Print",
"Rental Limit for members","Password"};
jList1=new JList(select);
MouseListener mouseListener = new MouseAdapter() {
public void mouseClicked(MouseEvent e) {
if (e.getClickCount() == 2) {
int index = jList1.locationToIndex(e.getPoint());
if(index==0){
Frame2 obj = new Frame2();
obj.setSize(600,600);
obj.show(true);
if(index==1){
Delete obj=new Delete();
obj.setSize(600,600);
obj.show(true);
if(index==5){
Rental obj=new Rental();
obj.setSize(600,600);
obj.show(true);
if(index==6){
login obj=new login();
obj.setSize(600,600);
obj.show(true);
jList1.addMouseListener(mouseListener);

how call a frame from a Servelt please

hi, you can output a javascript that calls a frame as follows
PrintWriter out=response.getWriter();
out.print("<script>");
out.print("window.frames['frameName'].functionCall();");
out.print("</script>");
good luck

How to stop frame from closing?

Hi,
ramka.addWindowListener(new WindowAdapter()
              public void windowClosing(WindowEvent e)
                  Object [] qqq = {"yes", "no"};
                  int answer = JOptionPane.showOptionDialog(
                            null,

              });as you can see above i want to stop frame from closing.
what should i do in the commented line?
or maybe somewhere else?
please help,
thanks

This is how you extract frames from video

right then, in answer to many posts about how to get the individual frames from video, here is my solution. it seems to work with mpg files but it doesnt seem to work with any of the avi files i tried. not sure why it doesnt work with those. i have modified javas frame access.
nothing is displayed except it prints which frame it is doing.
if anyone wants to improve it, please do. i still dont understand fully how it works so i probably wont be able to answer many questions about it. anyway here it is:

The quality of the produced video from this example is very poor.
It comes to huuuuge surprise the following fact.
If you comment the line where you set the PostAccessCodec, the chain of the codecs is:
MPEG-1 decoder -> YUV2RGB -> Direct Draw Renderer. ( The one used from the system to decode and render)
If you run the example purely as is above you get the following sequence(as long with the poor quality):
MPEG-1 decoder -> YUV2RGB -> Windows GDI Renderer.
So you say lets set another Renderer. So
you add the following line videoTracker.setRenderer( new DDRenderer() )
What comes to a surprise is the following chain of codecs:
MPEG-1 decoder -> YUV2RGB -> Post Codec -> Java RGB Converter - > DDRenderer
The quality now may be perfect but video runs to slow. The surprising thing here is that even though we have set the outputFormat of the PostAccessFrame codec to RGBFormat the system converts it again to RGB through codec Java RGB Format.
After searching a lot and reaching the conclusion that the deference between the 2 RGB's is their sizes I sudently was brought in front of a method called grabFrame(). Bels started ringing inside my head. Starts were comming up. Looking at the definition of the class com.sun.media.renderer.video.DDRenderer I descovered that this damn class implements the FrameGrabbingControl Interface. What the f.....? The problem that consumed 4 days of my life and multiplied with 10 to give hours has finally come to an and.
Summing up the solution for grabbing frames is this!!!!!

Disposing frame from other class

Hello,
I have a problem closing another frame by pressing the button in a frame.
I have this method in the frame I want closed
public void closeWindow()
        dispose();
        System.out.println("==========================");
    }And I call the method using this piece of code
    public class btnOkHandler implements ActionListener
      public void actionPerformed (ActionEvent e)
          //deleteUser();
          dispose();
          ftest = new frmTest();
          ftest.closeWindow();
    }So the btnOkHandler class should dispose both the frame where the button is in (wich it already does) and it should dispose the frame frmTest wich it won?t do.
I guess it won?t dispose it because it opens the frame with this piece of code :
ftest = new frmTest();But I can?t seem to find a work around of how to call the method with dispose(); in it from frmTest.

Late reaction I know, but I still havent figured it out.
I will post a sample code of what I mean.
I will post a code for frame1 and frame2.
A button in frame1 opens frame2, and a button in frame 2 should close frame1.
I have commented out what doesn't work. Well actually it does work but it doesn't work how I want it.
I figure it bugs because I make an instance to frame1, and it disposes it. So basically I have:
Frame1 open
Frame2 open
Instances frame1
Another frame1 open
Closes frame1, still leaving 1 frame1 open.
Could anybody suggest how I could get rid of the instance new Frame1 but still being able to dispose that frame?

Help - how do I transfer from ipod to library

Hi all,
I have downloaded itunes onto a new computer and somehow managed to delete the file (when I thought I was transferring it) from the old computer. Therefore I have lost all of my library. I have still got all my music 5000 songs on my ipod and iphone however. So I'm trying to figure out how to get my music from the ipod and import it back into the library, without itunes wiping everything off my ipod (as current library on new computer) only has all my purchased songs. Alot are from cd's, etc...
I hope you can help me.
Thanks

Sync is only oneway, from PC to your device. Unless you have the music on your PC, iTunes is going to wipe out what you have on your device if you are syncing to a new library.
You can only transfer Purchased music over to Itunes on your PC.
iTunes Store: Transferring purchases from your iOS device or iPod to a computer
http://support.apple.com/kb/HT1848
As for you own music, you may have to use a third party software. A good Free one is called Sharepod which you can download from Download.com here:

HELP How to rescue data from a HD with only the Terminal utility working

I can no longer access the hard disk on a 2008 unibody Mac Book after an failed OS upgrade (?). Running the original OS 10.5.5 from the grey CD-ROM that came with the device and using the "Terminal" utility, I find all data in their place and within the correct structure.
I tried to make an image of the HD or to copy the files to the external disc using the Hard Disk utility, but all attempts have produced an "operation not possible" message. Target mode will not work, as the device has no firewire connection implemented.
How can I access the files (I know they are there, I can see them...) and e. g. copy them to an external disc or rescue them with an other method?
PLEASE HELP ME
Thank you, Martin
PS Please don't tell me that experienced users will always have backups of their files: It is my wife's device and that's exactly what I have been telling her for years. Still, it's my wife...

Click here and choose 10.5 from the menu for usage instructions. Installing the OS on an external drive is done the same way as doing it on the internal drive, but it needs to be formatted as Mac OS Extended (Journaled).

HELP How to download music from Musicstore to play on MP3 Player

I just bought a okley sunglasses with MP3 Player... How can I buy music in a MP3 format on internet... Apparently the only way to buy/download music from internet on a mac it's with the music store but then it won't allow me to convert it into a MP3 file!!!! Do you have any solutions.. please help me i'm desperate... thanks

There is a workaround.
You have to burn purchased music on Audio CD first, then re-import it in the format of your choice.
If you buy complete albums, this method is economic and you have a backup.
For single purchases this won't be much of a help.

How to display backslashes from a command stored in a variable

I have a file list of Unix comands with backslashes and other special characters. I am reading it into a loop and running the commands. At present I have :
cat Udata
LineNum=1
while read line
do
     echo
     echo
     echo "**********************************"
     echo "Process $LineNum"
     echo "Code is     >> $line"
     echo "Results are: "
     echo
     eval "$line"
     (( LineNum++ ))
done < hmregraw
hmregraw is the file with the commands such as
grep '\tA.:' Udata
The \ is not printing and in eval it is trying to run
grep 'tA.:' Udata
which is wrong. The line being read into the while loop from hmregraw has the \ removed. How can I preserve those backslashes? Is there a way I can do this with out modifying the other departments or creating another duplicate file?
Thank You.

The 'read' is removing the \
Try using read -r
See man bash

Help, how to export emails from mail app

hi guys: I did not uncheck the box remove emails from the server after ..... so my hotmail on the server are gone. i want to have email copys stores on the server, since i need to check hotmails from any computer, not just on my home computer where the emails backup copys are stored. so i want to export my emails from the mail app in the mac back to hotmail server, how can i do that?? please give me a hand, i will really appreciate

You can do it via Mailbox>Archive Mailbox. And also, based on what you're saying you have Hotmail set up as an POP account in Mail. Don't know if Hotmail offers it, but if you set up the Hotmail account as IMAP in Mail then the behaviour will be different. You will have two copies of the emails on both the server as well as the computer. Go to Hotmail's help section and type in keyboards like "IMAP" and "Apple Mail."

Please help: How to pass variable from main select to subquery

I have a table with four columns (id, status, start_date and end_date) as follows. What I want is to get the difference between the statuses' start_date to find out how long it takes for the ID to change status. Basically getting the difference of the Start_dates of the statuses for the ID.
ID         Status               Start_date          End_date
1         NEW             02-FEB-07        02-FEB-07
1         OLD             04-FEB-07        06-FEB-07
1         BAD             09-FEB-07        14-FEB-07
I had initially thought of doing this
SELECT ID, (SELECT Start_date from tbl where Status = 'OLD' and ID = 1) - (SELECT Start_date from tbl WHERE Status = 'NEW' and ID =1) from tbl where ID = 1
but that would not work since I have more than one id and implementing inside Java will be complicated. Please help me what I need to do .. Thank you
