How to make buttons of Strings from a db
I have this program "SokGenre" which connects to a db and take out some Strings and put them in a vector.
Now I would like to have an applet with Buttons and each button shall have text from one of the strings from the db.
Any tips? How shall I do?
How do I "link" the programs to eachother? Im a newbie....
import java.sql.*;
import java.util.*;
class SokGenre {
public static void main(String[] args) {
Connection conn = null;
try {
Class.forName("org.gjt.mm.mysql.Driver");
conn = DriverManager.getConnection( "jdbc:mysql://localhost/MyDb?user=root&password=" );
Statement stmt = conn.createStatement();
String query = "SELECT Gnamn FROM genre WHERE Gover='-'ORDER BY Gama";
ResultSet rs = stmt.executeQuery(query);
Vector vektor = new Vector();
while (rs.next()){
vektor.addElement(rs.getString("Gnamn"));
System.out.println("Vektor: "+vektor);
catch(Exception e) {e.printStackTrace(System.err);}
finally {
try {conn.close();}
catch(Exception e) {e.printStackTrace(System.err);}
Here's some info on Applets.
http://java.sun.com/docs/books/tutorial/applet/index.html
You can create a Button using a String so that shouldn't be any problem. You can add Buttons to an Applet. You will have to learn about ActionListeners if you want your program to do something when a Button is clicked.
The code you have might be included in the Applet class that you create. Or you might have a button to "Retrieve" the data from the db and clicking the button causes the ActionListener to call the SokGenre main method.

Hello Anybody, I have a question. Can any of you please suggest me how to make an xml file from the database table with all the records?
Note:- I am having the XSD Schema file and the resulted XML file should be in that XSD format only.The Oracle documentation has a good overview of the options available
Generating XML Data from the Database
Without knowing your version, I just picked 11.2, so you made need to look for that chapter in the documentation for your version to find applicable information.
You can also find some information in XML DB FAQ -

Hi guys,
How do I Display a string from a servlet into a JSP Page...
Ive tried so many bloody things!.....
Simply.
I get text from JSP. The servlet does what ever it does to the string.
Now. Ive create sessions and bean things,.... how the hell do I display it in a text box... I can display on the screen.. but not in the text box.!!!
please help!!!hmmm, I dont really like using JSP programming, u should be using JAVA..
the way to do it is:
Call and cast to the bean like this:
<%@ page import="beans.*" %>
<% //cast to bean get request create object
userNameBean u= (userNameBean) request.getSession().getAttribute("userNameBean");
then... all you do is call it like this:
<input type="text" name="firstName" value="<%= u != null? u.getFirstName(): "" %>">
this is the real programmers way,,,

How to make a ARCH package from local folder?
hello ARCH lovers
I can't seem to figure out how to make a installable
package from a folder on my desktop?
Coming from Slackware; the procedure would be simple enough just issuing
"makepkg /root/pkgname.txz"
Now; how would I do the same in ARCH?
I know about PKGBUILD, etc but there is no source or any url's
I just need to make it into a .pkg.tar.xz
The package is my "kernel-live-kit" for both x86 and x86_64 versions of arch
enabling one to remaster there existing install into a livecd/usb, etc
The kernel itself is kernel26-zen from AUR
http://aur.archlinux.org/packages.php?ID=30330
however; mine is quite different and also includes all components to make the livecd using modified linux-live-6.3.0
scripts and special stuff
The pkg includes a premade kernel with modules and full kernel source
The resulting live media is similar to my nFluxOS builds
http://multidistro.com/
As I will be releasing the new four horsemen of nFluxOS today; I also made 4 Kernel pkg's for the arch and slack versions
Those will be for x86/x86_64 versions for both arch and slackware
I did this in lieu of creating a quartet of x86_64 versions of nFluxOS; as that would up the number of versions to 8
and I would then have to maintain 8 distro's instead of 4.
I made a testing version of ARCH x86_64 live
http://www.linuxquestions.org/questions … ost4017796
so, I really need to make the ARCH x86 and x86_64 kernel kits into installable pkg's because there are many symlinks that would get corrupted if I just tarred it and then the end user untars it and copies it somewhere it would mess up the symlinks.
as I said, in slackware I do makepkg and it creates a script named "doinst.sh" that makes all the symlinks, etc
so, any help appreciated!
thanksYou can read a simple introduction to using the ABS here.
By the way, it's not hard. Out of all the distributions I've used, Arch Linux is the only one I've figured out how to make packages for. -
Not clear how to make button iconic
i am not clear how to make button in forms iconic and where that icons come.where i have to kept that specific icon.what is the path of the directory where to keep image
Just to add a little on what Gerd said, for web deployed forms your icon files must be of type .gif
You cannot have .ico files in web deployed forms
For more information on Web deployed icons read [url http://www.oracle.com/technology/products/forms/pdf/webicons.pdf]Webicons
If you're using client/server technology, you also specify the UI_ICON registry and put your icons under that directory. In client server you can use .ico files

Make Button load Words from List
Hey Guys!!!
Just a note, I dont know about proramming and I am new to flash so please say you responses in the simplest way possible, thankyou!
So I am making an app that when you click a button it will randomly select a Who, What, When, Where, and Why from a list that I make.
So say there is a button that says New Idea.
When I click the button there is:
Who:
What:
When:
Where:
Why:
Say a small list of who is 1, 2, and 3
A small list of what is 4, 5, and 6
A small list of when is 7, 8, and 9
A small list of where is 10, 11, 12
And a small list og why is 13, 14, and 15
How can I make it so when I click the New Idea Button it will select (by random) a who, what, when, where, and why from their lists?
Please help me saying what to do from making the button make get a word from a list, to what I am asking!
Please!!!
Thankyou!!!To make a random selection from a list you first have to have the list. An array makes a good list, so for each category create an array and fill each with whichever choices you intend.
To randomly pick one of the items in the list you can use the Math methods that Actionscript is supported by.
var whoList:Array = [1,2,3];
var randomWho = whoList[Math.floor(Math.random()*whoList.length)];

Hello!
I have 3 iOS devices synced with iTunes apps library (OS X 10.10.2)
Can someone tell me how to make not only added but deleted apps be synced also? I mean I want an app deleted in iTunes library be deleted from any iOS devices synced with this library.But it was working some time before! What and when has changed?
There was even a warning popup window something about "this application will be deleted from all the devices synced with this library"
Now there's opposite message - "This application will not be deleted from any device syncing with this account". Isn't it some kind of clue that there can be conrarily circumstances - when application IS deleted from ANY device synced with this computer? -

How to make buttons enabled after the data is entered in JTextField?
I got a JTextField. I want to test the entered data in JTextField is eight length. If the data is of length eight then i want to enable two buttons. How to make it enable? I am getting the length eight, but the buttons are not enable. What listeners I have to use.
Can anybody help me out.
Thanks for your help in advanced.Create a class that extends KeyAdapter. Add a field that is an array of buttons. Override the keyTyped(KeyEvent e) method to use getSource() to access the text area, check the length of the text, and if > 8, go through the array and enable the buttons in the array. Then, when you create the text area, create an instance of your listener, passing it an array of the two buttons you want to enable, and then use addKeyListener(yourKeyListener) to add your key listener to the text area.
