I need an applet where a user enters (or cut-n-pastes) a UTF-8 string into a TextField. Then the user presses a button, and the UTF-8 text is copied into a string.
|
|
|
|
|
Then write one?
What is your specific question/problem?
Don't let my name fool you. That's my job.
|
|
|
|
|
I figured it out shortly after creating this post. I'm using JavaCC to parse my UTF8 inputs, and it's working fine! Thanks for your reply.

I was wondering if anyone could help me. I have a number of .JAR files which I want to be able to access from VB. I have downloaded a utility which converts the .JAR file into a .DLL which means I can access it using VB code. Unfortunately the software was evaluation only and very expensive. Does anyone know of a free utility that does this or another solution ? The software was from the following site:

Dear All,
I've been trying to display the Tif image into the WebBrowser with the help of Applet embedded into a JSP through NetBeans IDE.
To achieve this goal, I've created 2 projects "NewApplet" which contains the Applet class and "WebApplication1" which has "Index.JSP" which embeds the Applet.
If i execute Only the Applet, it displays the TIF. But if i execute the JSP, it fires the following error:
"URL Scheme is not "file" http://localhost:8084/WebApplication1/alpesh.tif""
Following is the code written NewApplet.Java:
package display;
import javax.swing.JApplet;
import java.awt.BorderLayout;
import java.awt.image.RenderedImage;
import java.io.IOException;
import javax.swing.JDesktopPane;
import javax.swing.JInternalFrame;
import javax.swing.JScrollPane;
import com.sun.media.jai.codec.ImageCodec;
import com.sun.media.jai.codec.ImageDecoder;
import com.sun.media.jai.codec.TIFFDecodeParam;
import com.sun.media.jai.widget.DisplayJAI;
import java.io.File;
import java.io.FileInputStream;
import java.net.URI;
import javax.swing.JOptionPane;
public class NewApplet extends JApplet {
@Override
public void init() {
URI FileName = URI.create(getCodeBase().toString().concat(getParameter("imageSource")));
try
{
File f = new File(FileName);
FileInputStream stream = new FileInputStream(f);
// Create a decoder using that stream.
TIFFDecodeParam tiff = new TIFFDecodeParam();
ImageDecoder dec = ImageCodec.createImageDecoder("tiff", stream, tiff);
// Get the number of pages.
int pages;
pages = dec.getNumPages();
// Set the application title.
setTitle(pages+" pages in "+filename);
// Create a JDesktop to hold the pages in internal frames.
JDesktopPane desktop = new JDesktopPane();
//getContentPane().add(desktop,BorderLayout.CENTER);
desktop.setSize(400,400);
add(desktop,BorderLayout.CENTER);
// Open all images in the TIFF into the desktop pane.
for(int i=0;i<pages;i++)
{
// Get the image.
RenderedImage ri = dec.decodeAsRenderedImage(i);
// Create and set the user interface of an internal frame.
JInternalFrame jif = new JInternalFrame("Page "+i,true,true,true,true);
jif.getContentPane().add(new JScrollPane(new DisplayJAI(ri)));
jif.setSize(400,400);
jif.pack();
jif.setVisible(true);
// Add the internal frame to the JDesktop.
desktop.add(jif);
}
// Set the application closing behaviour, frame size, and show it.
//setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setSize(400,400);
setVisible(true);
}
catch (Exception e)
{
JOptionPane.showMessageDialog(this, e.getMessage(), "alert", JOptionPane.ERROR_MESSAGE);
}
}
}
Following is the code written Index.JSP:
<APPLET code="display.NewApplet" ARCHIVE="NewApplet.jar" width=350 height=200>
<param name ="imageSource" value="alpesh.tif"/>
</APPLET>
Any Guesses?
I've added the "dist/NewApplet.jar" in WebApplication1 through the option of "Properties->Build->Packaging" in NetBeans.
Please help!

i am using vector data structure in my code
1- i create the following vector of vector:
Vector<vector><integer>> dataVector= new Vector<vector><integer>>();</integer></vector></integer></vector>
and i need to do the following if some condition is true , create new vector and add to the dataVector
maybe somthing like this
if (condition==turu)
then creat new vector
dataVector.add(new vector)
can any one help me

sudany_zool wrote: Vector> dataVector= new Vector>();
this is badly formatted.
did you mean Vector<Vector<Integer>> ?
anyway, where are you stuck exactly ?
and to understand your problem better, what is your "vector of vector" supposed to represent ?

creating a cell class.
The first should be called Cell. It represents one cell (square) of the tic-tac-toe board. It should contain at least one property, the character which occupies the cell. You may use either a blank character (‘ ‘) or a null to indicate an empty Cell, but I think you will find that the blank works better. Cell must also contain the following methods:
Constructor - create the cell and initialize the letter in the cell.
void setCell( char letter) - set the value in the cell.
char getCell( ) - return the letter in the cell.
boolean isEmpty( ) - return true if the Cell holds a blank, false otherwise.
|
|
|
|

so, what's your question exactly ?
are you totally stuck with it ? or have you already started something ?
as you might know (you are not supposed to ignore the rules out there), we don't do homeworks...

I would start by creating a text file named after the class you are supposed to create, but with the appropriate extension for a source code file.
We will call this the source code file.
Inside that file, I would declare a class using the standard class declaration syntax, which you can find if you look at any Java HelloWorld program.
Inside that declaration, I would declare 4 methods (or 1 constructor and 3 methods, if you prefer) using standard constructor/method declaration syntax. Again, find a HelloWorld program. Better still, see the last 4 lines of your question, where you have everything but the braces {}.
You would also like to have at least one member variable (the property), which you can name Harvey. Harvey, I think you will find, works better than Fred. But you can call it Fred if you must. Never call it Farqhuat, because people will laugh at you.
The constructor should ponder the existence of itself, asking such things as "Why am I here?", "Who made me?", "Of what use am I?", and "Does peanut butter always have to have jelly to make a good sandwich?" You should not code any of that, but it must be implied. See Webster's Dictionary for an example of implying.
The setter method should ideally set something, and the getter method would, in a perfect world, get that thing. It's up to you to make the world perfect.
The test method, on the other hand, should not lie about the contents unless it is a Tuesday.

Hi to all, I need some help in getting the union of of 2 interacting polygons.
Currently I have managed to draw 2 polygons p1 and p2, and I got stuck on getting the unions between the 2 polygons. I have tried using the java.awt.geom, but later realized that the geom package can only be used for regular shapes.
This is part of my code:
Polygon p1 = new Polygon();
for (int i = 0; i < 5; i++)
p1.addPoint((int) (200 + 50 * Math.cos(i * 2 * Math.PI / 5)),
(int) (100 + 50 * Math.sin(i * 2 * Math.PI / 5)));
g.drawPolygon(p1);
Polygon p2 = new Polygon();
for (int i = 0; i < 5; i++)
p2.addPoint((int) (160 + 50 * Math.cos(i * 2 * Math.PI / 6)),
(int) (60 + 50 * Math.sin(i * 2 * Math.PI / 6)));
g.drawPolygon(p2);
Please help. Thanks.

1) we don't do homework here.
2) read the forums posting guidelines
3) "the int type has a limitation: it can’t store integer values larger
than 231"
Where the f*ck does this come from ?????
|
|
|
|
|
I would assume that by 231 he means 2^31, which is the limitation for a signed int.;
As for the question, what you are going to have to do is remember back to gradeschool, when we did longhand arithmetic.

Write out psuedo code on how to do this, then implement it. isValidBigInt should be easy.

this is fundamentaly different, and moreover, WRONG.
the higher value an unsigned int can take is (2^32)-1, which is 4 294 967 295.

Thanks, must of had a brain fart when I read it.
|
|
|
|

As far as I remember, there is only signed int in Java, so its maximum value would be (2^31)-1 (2,147,483,647).
