Deployment problems that I don't know how to fix or draw - Please Help
I did a javafx in netbeans application when I import the classes in the java library (specifically those of java.io for the writing/readning files). The program works fine in IDE, reading and writing files, but when I build and run the .jnlp, not write all files or doing nothing which requires imported functions. I have tried for a few weeks now and have had no luck. The same thing happens when I create a new javafx desktop application and try to write a simple text file.My questions are the following:
1 does anyone know if I'm missing something? I tried checking the box that makes a connected individual jar and pack200 compression, no luck. This program is run locally on the user's computer.
2. I do not not how to check for traces of the application exception would be thrown. I use Mac OS x 10.6.6 and the latest Java and Netbeans. Can someone help me with this?
My deadline is coming and I don't want to rewrite it using something else. I was happy with this so far javafx application. Help, please
Here is my test .fx file
package savetest;
import java.io.BufferedWriter;
import java.io.FileWriter;
import java.io.File;
import java.io.IOException;
import javax.swing.JFileChooser;
public class Main {
// <Generated Code by netbeans (unaltered or edited for this test)>
}
function writeData(source : java.net.URI) {
var output: BufferedWriter;
try {
def text = "Test Data";
def file = new File(source);
output = new BufferedWriter(new FileWriter(file));
output.write(text);
output.flush();
output.close();
} catch (e: IOException) {
e.printStackTrace();
}
}
function run (): Void {
var design = Main {};
var fileChooser : JFileChooser = new JFileChooser;
var goalURI : java.net.URI;
javafx.stage.Stage {
title: "Main"
scene: design.getDesignScene ()
}
if (fileChooser.APPROVE_OPTION == fileChooser.showSaveDialog(null)) {
goalURI = fileChooser.getSelectedFile().toURI();
}
writeData(goalURI);
}
The null value of your pass at your writeData(source: java.net.URI) function.
Validate your argument of function:
function writeData(source : java.net.URI) {
if (source == null) {do something}

To generate a pop-up, but I don't know how it's called. Please help a noob.
I saw this type of pop-up windows a lot with news sites and the artist portfolios and I want to appear on a product site I'm building, but I don't know what they are called so I can't find the code to help me to build.
Essentially, there is a photo or another link on the main site and when the veiwer clicked, the site goes dark gray and the pop-up "fills" the screen and give a larger view of the image or the image with additional text. Sometimes there are directional arrows for more views and then there are the 'X' to close the pop-up and the main site goes back to normal.
What we call that? Once I know I can Google how build it!
Thank you all very much.

my itunes does not work due to a DEP problem and I don't know how to fix it
can anyone help my get my itunes to work again for the DEP will allow him to open
Hi bspack12,
1. you receive messages or error codes?
Data Execution Prevention (DEP) is a security feature of Windows, tracks how programs use memory. If DEP finds memory used incorrectly, DEP closes the program and let you know.
Step 1:
Try the following steps to turn off DEP for iTunes and check if you open iTunes.
a. open system by clicking the Start button, clicking Control Panel, clicking system and Maintenance, and then click System.
b. click on advanced system settings. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.
c. running, click settings.
d. click the Data Execution Prevention tab and then click on turn on DEP for all programs and services except those I select.
e. restart and see if it is resolved.
Check out the link:
Change Data Execution Prevention settings

If you're still having problems, you can read the following article and try to uninstall and reinstall iTunes:

Don't know how to fix a problem of text? Somewhat of a novice to this just and kept copying and pasting text boxes. now that I'm done and am trying to export to a PDF file I get the error text. How can I fix it... in simple terms, please
Red + the way there is more text than is view - or overset text. You can extend the text box to enable all to show, or create another text box and pour the rest in that one.
Sometimes if you don't know that there is no more text, it's maybe a return which InDesign thinks that there is no more.

Adobe Bridge in CS6, the metadata model is wrong, and I don't know how to fix it
(Windows 7 64-bit) Adobe Bridge in CS6.
Until two weeks ago, I could open any of my picture files, and then click file, information file. Categories of metadata would be displayed, including the first category of page that has the copyright, author, description, keywords, etc..
Recently, the first category of the page is missing. I don't know how it happened, and I don't know how to fix this to return to the metadata with all categories.
It is not a question to edit new metadata, because the correct category is absent, there is no correct place to put the missing metadata.
I tried to create a new metadata template which has categories, but I can't understand how Adobe Bridge to use for picture files.
Any suggestions?

My A940 dell printer spooler is disabled. I don't have how to restart it. Please help PS I have awindows XP 32 PS my email is * address email is removed from the privacy *
The people who answer questions here are, for the most part, volunteers who have no connection with Microsoft. Ask your question every two minutes won't get you a faster response.
Often, but not always, the symptoms you describe are caused by a corrupt print job stuck in the queue or a damaged printer driver. However before you clean things up, on general principles, that you can download, install, update and run full scans with each of these two free programs:
AntiMailware MalwareBytes
SUPERAntiSpywareDo not operate the two scans simultaneously. Each will take a long time, so start it and then go do something else for a while.
Cleaning of printers
NOTE: If after completing step has the spooler print don't rest not always running after you launched the command "net start spooler", follow these steps
Open a command prompt window (start > run > cmd > OK)
Type the following line in the black command prompt window
dependent on the spooler of sc config = RPCSS
net start spoolerIf the spooler still will not start, you will not be able to follow all the steps in "First Article". Instead, go to the other link and download and get and use the utility 'cleanspl' such as described here.
A. Clean on print jobs pending
- Open a command prompt window (start > run > cmd > OK)
- Type the following in the black command prompt window, and then press ENTER after each line
net stop spooler
del/q '% windir%\system32\spool\PRINTERS\*.* '.
net start spooler
outputB. clean the old printer drivers and install the latest drivers by using the directions in One Article. If you have (or had) a Lexmark printer, follow the instructions on the following site before installing the new drivers, as explained in its first Article: http://members.shaw.ca/bsanders/CleanPrinterDrivers.htm
