Can we use JTable in a JTree?

Hi Actually this is my first mail to this forum.
I want to use a tables embedded in a tree . You can see such format in VB's Properties sheet's "Categorized" tab. Has anyone tried doing such format. Or anyone knows if it is possible to do it in Jtrees. If yes then how?
Anybody knows? Pls mail back.
Regards,
Amit.

Hi,
Thanks for the reply. This will definately serve my purpose, but i cannot compromise on the GUI. But, Is there a way by which I can have table on the click of a tree node and not JTree as a renderer for the cells in a JTable.
Pls mail back.
Regards,
Amit

How Can I use JTable Like Datagrid (Spreadsheet) and database

Please how can I achieve the following in java:
(1) Create a Grid (spreadsheets-Like) with JTable and be able to add new record (rows) as I reach the end of the last column during data entry.
(2) Save the content of the grid to a text file as well as a database.
(3) Retrieve the content of the text file or database to the Jtable
(4) How can I connect to SQL Server without using JDBC-ODBC-bridge and also with Oracle.
(5) How can I read and write to LPT and COMS ports

If you don't know how to do any of this, you need to go through the tutorials. Start here: http://java.sun.com/docs/books/tutorial/

Can't use import javax.swing.RowFilter; in javafx

Dear all,
I'm a question for you.
I developed a javafx application in which I use also swing dialog and swingx libraries.
The question is I can't use jtable filter of java jdf 1.6
That is when I try to add in my netbeans javafx project
import javax.swing.RowFilter;
it says me it's not correct library
If I create a java swing application I can add this include.
Why it?
I edited netbeans conf to set javafx sdk to javafx lib I downloaded (whole sdk), not that one with netbeans, but nothing.
It seems like I can't use this import in javafx application.
Is it posbbile?
Please help me

The reason you cannot use it is because javax.swing.RowFilter was introduced in Java 1.6 . Netbeans compiles JavaFX to work with Java 1.5, which does not have the class in question.
I have gotten around this by going to the properties->Libraries->Add JAR/Folder menu and included the jre/lib/rt.jar file from the jre directly into my project.
Someone else posted a similar solution and more detailed explanation here: http://steveonjava.com/hacking-javafx-10-to-use-java-16-features/

How can i use or embed the ' C' language in java

thanks a lot friends for your suggestion on using 'c' language to implement the control of the keyboard ie. to prevent a key stroke of : ctrl+alt+delete keys from closing a running java application. i was advised that it won't be possible to implement this with java language, the use of 'C' language was suggested. i then wish to ask the following:
1. how can i use 'C'language in a java program and be able to compile to program so that the resultant program can help me prevent the closing of my java-application when the user of the application presses the following keys : ctrl+alt+delete. i don't even know the c language at all. how can i start and how can i combine the resultant code with java.
2. i'm thinking of creating an application that retrieves information from a database, like microsoft sql or oracle, and displays the resultant data from a table, say STUDENT TABLE, in a java application using the JTable class. i don't even know how to use this JTable but i've seen it used and know it will suit what i have in mind.
3. how can i make the table dynamic, ie. how can i make the table to immediately register / show the result of an update to the 'STUDENT' table in the database.
4. THANKS FOR YOUR HELP IN ADVANCE. i will most appreciate it if you can give me a sample code or a site where i download one. once again thanks.

Good luck disabling Ctrl+Alt+Del! I've read quite a bit about it, and at least on Windows 2000 (not sure about NT) or higher, disabling it is next to impossible. Problem is CAD is a system command, and the OS doesn't even send the keys to the active program. Ctrl+Alt+Del is handled by the GINA (Graphical Identification and Authentication) DLL installed on the system. You'll have to write and export the functions you need and change the GINA DLL used by the system to your own. Bear in mind that any small mistake in the dll can cause you to lose access to your computer if you haven't taken precautions!
On Windows 95/98, disabling Ctrl+Alt+Del is fairly easy as you just have to write some simple native code to fool the system that a password protected screensaver is running.
I've provided a link regarding winlogon and GINA here, but you've been forewarned!

The Swing tutorial on "How to Use Tables" has examples of how to hardcode a 2-dimensional array to build a TableModel.
http://java.sun.com/docs/books/tutorial/uiswing/components/table.htmlYou can also use the addRow(...) method of the DefaultTableModel to dynamically add rows to a table.

How can I save JTable column order and widths?

Hello,
I'm trying to find a way to save the current column order and widths in a JTable, so that the next time the same user runs the app I can use these same settings. Ideally I'd like to save this locally on the user's PC. I think it could probably be done with serialization, but hopefully there's a simple solution. Anyone else already tackled this?

The JTableHeader class can give you all the information you through the various TableColumns.
I simply save all this information to a properties file which looks somthing like this
# Column Information
total=3
column0=Names,120
column1=Dates,140
column2=Status,110This can then be read back using a java.util..Properties object. With this information you'll need to manually set the properties of each TableColumn and use the column model to move the columns to the right position ie
cmodel.moveColumn(0,2); // move column 0 to positon 2This requires a little bit more coding to properly do the comparism of the column names with those in the properties object.
Tip: it is always easier to use the above format, ie column0, column1, column2, etc, so that you can easily use a loop to access the information form the properties object ie
int total = Integer.parseInt( prop.getProperty("total") );
for(int i = 0; i < total; i++) {
String cname = prop.getProperty("column" + i);
/// the rest of the TableColumn formatting could go here
}All the best.

In alv report can i use control break events? if no .whay?

Hi all,
in alv report can i use control break events? if no .whay?

hi,
you can use control break statements in ALV report.
for example: if one PO is having more than one line item, that time you need to display PO only once.

HT1751 I need to uninstall and reinstall iTunes (it won't let me update). So, how do I copy or back up my iTunes library of over 1,500 songs? Can I use a Flash Drive to do so?

I need to uninstall and reinstall iTunes (it won't let me update). I have IE 8 on Windows XP, and iTunes 10 something. In my Program files list I see iTunes and iTunes (2) and even iPod and iPod (2) where a tech had to back up and do this for me before. I'm just trying to fix it all. I keep getting the "The feature you are trying to use is on a network resource that is unavailable. Click OK to try again, or enter an alternate path to a folder containing the installation package 'iTunes.msi' in the box below." I can even run a search and find the folder, but it gives me the same error message. I was planning on using the Microsoft Fix-It tool to help uninstall then Reinstall iTunes. But I need to backup my library. So, how do I copy or back up my iTunes library of over 1,500 songs? Can I copy the folder to desktop or can I use a Flash Drive to backup my music? I don't want to do anything until I know for sure how I can backup my songs, and then reinstall them into iTunes. Thanks for any help.

Ok, thanks that helps. I don't have an external hard drive though. What about backing up through 'the cloud'? I'm just wondering since my husband syncs his iPod to the PC through iTunes and he's worried that he will lose all the songs on his iPod if the library is lost from iTunes and he tries to 'sync' it up again. I'm not exactly sure how to 'copy the entire iTunes folder' either. I kinda suck at this unless I have step by step instructions, which I haven't found yet on iTunes help or other sources.
The only way I know how to back anything up is by going back to a restore point, etc. (as stated before, we don't have an external hard drive.)
Thanks for the info.

How can I use 2 Apple IDs in Itunes? I have 2 IOS Devices. They each have there own AppleID. What is the proper way to sync both of them to Itunes?

How can I use 2 Apple IDs in Itunes? I have 2 IOS Devices. They each have there own AppleID. What is the proper way to sync both of them to Itunes? I wanted my teenager's AppleID to be different from mine so that she couldn't charge stuff to my AppleID, therefore I created me another one. Now when I go to Sync either device, it tells me that this IOS device can only be synced with one AppleID. Then I get a message to erase it, not going to do that, lol. If I logout as one ID and login as the other, will it still retain all synced information on the PC from the first IOS device? If I can just log in out of the AppleID, then I have no problem doing that as long as the synced apps, music, etc stays there for both. I am not trying to copy from one to the other, just want to make sure I have a backup for the UhOh times. If logging in and out on the same PC of multiple AppleIDs is acceptible then I need to be able to authorize the PC for both devices. Thanks for the help. I am new to the iOS world.

"Method Three
Create a separate iTunes library for each device. Note:It is important that you make a new iTunes Library file. Do not justmake a copy of your existing iTunes Library file. If iTunes is open,quit it.
This one may work. I searched and searched on the website for something like this, I guess I just didn't search correctly, lol. I will give this a try later. My daughter is not be back for a few weekends, therefore I will have to try the Method 3 when she comes back for the weekend again. "
I forgot to mention that she has a PC at her house that she also syncs to. Would this cause a problem. I am already getting that pop up saying that the iPod is synced to another library (even though she is signed in with her Apple ID to iTunes) and gives the pop up to Cancel, Erase & Sync, or Transfer Purchases. My question arose because she clicked on "Erase & Sync" by mistake when she plugged the iPod to her PC the first time. When the iPod was purchased and setup, it was synced to my PC first. When she went home, she hooked it up to her PC and then she erased it by accident. I was able to restore all the missing stuff yesterday using my PC. However, even after doing that it still told me the next time I hooked it up last night that the iPod was currently synced with a different library. Hopefully, you can help me understand all this. She wants to sync her iPod and also backup her iPod at both places. Both PCs have been authorised. Thanks

Can I Use iTunes Store without Storing Bank Accounts, etc, in my Profile?

Hi
Today a fraudulent charge of $89.99 appeared on my iTunes account. This suggests that a hacker has obtained my password, and hence access to all information in my iTunes account, including credit card or Paypal account information. I can deal with having to claim refunds for fraudulent iTunes purchases, but I cannot afford to risk ID Theft, or to have my back account information in the possession of hackers.
(1) Is it possible to maintain an iTunes account that does not store bank accounts, and ideally stores no personal information other than my email address?
(2) If I can do this, I assume I'd then have to enter that information for each purchase. Will this information be expunged once the ourchase is complete? Or would it remain on the system in some form, accessible to hackers?
(3) If (1) is not possible, how do I cancel my iTunes account? There does not seem to be such an option on the iTunes Account Management screens.
Thanks,
Chris

You can remove your credit card from your account. Go into the account, click "Edit payment information" and you will see the option under credit card to click "None."
For purchasing, you can either enter the card info per transaction, or you can start using iTunes gift cards which are readily available.
