JFrame Not Responding To Dispose Function

Jun 13, 2014

I am trying to code a program which pops up a file chooser window or dialog box to select a file first, if the user clicks 'cancel' or closes the window then the parent JFrame would not show up.

Java Code:

import java.util.logging.Level;
import java.util.logging.Logger;
import javax.swing.JFileChooser;
import javax.swing.UnsupportedLookAndFeelException;
public final class base extends javax.swing.JFrame {

[Code] .....

The problem is that the JFrame shows up even if I click cancel in the file chooser. I am using Netbeans.

How To Attach OpenGL Display To JFrame And Dispose Off It Properly

Nov 12, 2014

How can i attach the OpenGl display to a JFrame and so that when i close the JFrame is destroys the display? Here is my code so far:

package test.core;
import java.awt.BorderLayout;
import java.awt.Canvas;
import java.awt.Color;
import java.awt.Component;
import java.awt.event.WindowAdapter;

[Code] .....

I had the opengl display attach to the JFrame before i did the runnable. But after adding the runnable the display now shows up the same size as my screen size. I have tried rearranging the

canvas.setSize();
and the
frame.setSize();

but nothing changes the opengl display is still the same size and when i try to close the JFrame first rather then close the display first i get this error:

Exception in thread "AWT-EventQueue-0" java.lang.IllegalStateException: From thread Thread[AWT-EventQueue-0,6,main]: Thread[main,5,main] already has the context current

which points me to my

Display.destroy();

which im guessing is telling me that i am not properly disposing the display? How to attach the opengl display to the JFrame and fix the error above?

The thing my coding for sudoku is not working for few inputs... it works fine with all its value initially at 0, but when i place numbers more than 4 at random places it stops responding (it doesn't show any value).

Mod Function With Multiples?

Jan 29, 2014

where I have to write a Java program that asks for user input regarding a book and provides information based on that input like the number of pages required, number of words on the final page and if the final page is more than half full, etc. We are told that each page should have 250 words maximum to use for our calculations. The problem I am having here is that when the total number of words is a multiple of 250 the output tells me that there are 0 words on the last page when in fact there are 250. I've tried messing around with mod functions in this format ((x+a)%250)+y which is what the professor told us to use instead of creating an if-statement for this case but I haven't been able to crack it. I don't think I fully understand how the mod function cycle could work for this case.

import javax.swing.JOptionPane;
public class CorreiaFranciscaA1Q1 {
public static void main(String[] args) {
String ManuscriptTitle =
JOptionPane.showInputDialog ("Please enter a book title.");
String AuthorName =
JOptionPane.showInputDialog ("Please enter the author name.");
String TotalWords =
JOptionPane.showInputDialog ("Please enter the number of words.");

[code]....

Above if totalWords is a multiple of 250 like 17500 then wordsFinalPage will give us 0 and I need it to give 250. How can I do that without using an if statement but instead using a mod function?

Calling A Function In JPA 2.1

Using JPA 2.1, I have been trying without luck to call a function that returns a REF CURSOR containing RECORD TYPES. Is there a way of doing this?
 
One Example of trying:

Query query = em.createNativeQuery("select my_package.my_function from dual");
Object a = query.getSingleResult();
 
I have also tried to use the StoredProcedureQuery though this does not look like it can return the functions value.

Function Calling In A Program?

Feb 12, 2015

I just wanted to ask that when we invoke a function by passing certain arguments in it ,so for instance I have certain variables like a,b and c with some values assigned to them,so when I invoke a function like func(a*b , 8, c+a) where the function func accepts parameters like func(int x,int y,int z) ,so is there any order of evaluation of expressions defined like the value of c+d would be evaluated first and then assigned to variable z ,because in C we have sequence points and since comma when acting like a separator is not a sequence point so any of the expression can be executed first ,so basically is there any sequence in which the function arguments are assigned to the parameters of the function or any relation with the stack implementation.

Even in C ,the printf starts executing its expressions from right to left so basically in why does it happen there when comma is a separator in a function argument.

Displaying Two Document From One If Function

Oct 15, 2014

So I have this

function checkvalue (val) {
if(val==='replaced')
document.getElementById('check1h').style.display='block';
else if (val==='checked')
document.getElementById('check1h').style.display='none';
else
document.getElementById('check1h').style.display='none';
}

Which works fine... But if I try and add another document under the if VAL === replaced then nothing works and neither of the boxes appear.

function checkvalue (val) {
if(val==='replaced')
document.getElementById('check1h').style.display='block';
document.getElementById('check1n').style.display='block';
else if (val==='checked')
document.getElementById('check1h').style.display='none';
else
document.getElementById('check1h').style.display='none';
}

Is this not possible?

Also, Both of my input type are set up like this...

<input type='text' style='display:none' name='check1n' id='check1n' placeholder='Name of Part' />
<br>
<input type='text' style='display:none' name ='check1h' id='check1h' placeholder='Part Number' />
