Help with simple calculation

I'm slowly learning myself Java through JBuilder 6. I'm currently on with a currency convertor, one of my first programs that does more than say "Hello world". Anyway, this is a section of my code
void submit_actionPerformed(ActionEvent e) {
String s = jTextField1.getText();
try {
val = Double.parseDouble(s);
catch (NumberFormatException exp) {
val = 0;
if (jComboBox2.getSelectedItem() == "US Dollar") {
dResult = val * dDollar;
else if (jComboBox2.getSelectedItem() == "Pound Sterling") {
dResult = val * dPound;
else if (jComboBox2.getSelectedItem() == "Euro") {
dResult = val * dEuro;
else if (jComboBox2.getSelectedItem() == "Bahrain Dinar") {
dResult = val * dDinar;
else if (jComboBox2.getSelectedItem() == "Australian Dollar") {
dResult = val * dADollar;
else
dResult = val *dYen;
jTextField2.setText("" + dResult);
void jButton1_actionPerformed(ActionEvent e) {
jTextField2.setText("" + dResult);
The idea is for the user to enter their amount, select which currency they want from the combobox, then the result is displayed back to them. However, each time I run this program as it is, the result is always zero. I assume there's something wrong in the calculation, can anyone help me?

Thanks, how would I do that? I have this code in my program too (I haven't posted the whole thing)
private void jbInit() throws Exception {
this.setSize(new Dimension(400,300));
jButton1.setText("Convert");
jButton1.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(ActionEvent e) {
jButton1_actionPerformed(e);
jTextField2.setText("Result");
jTextField2.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(ActionEvent e) {
jTextField2_actionPerformed(e);
I did try adding another actionListener, but the program would not work when it was inserted. Thanks for any help!

Help with a Calculation Script

I'm not sure if this is possible or not, but I have two checkboxe options on a form. When an item is checked, I want the total form to update, but I can't get it to work.
So CalcLine1 is a checkbox with an on value of $825.12
and CalcLine2 is a checkbox with an on value of $20
As the boxes are checked, I want the numeric field CalcTotal to update. I have it set with a Value Type of Calculated-Read only, but don't know where to go next.

Hi,
I am a new user and need to do some simple calculations, preferably without creating script. I have a series of check boxes which I want to equal "1" when checked. I need them to subtotal and then total.
I am using LiveCycle 8.0. There is no database behind this form although that would be a possible future enhancement.
Also - is there a good resource for understanding the basic manipulation of forms - answering questions like - What is a sub form? Can I insert a field in the middle of the form and have everything move down? Everything I have found deals with a more complex level of form creation, yet the help screens don't give enough of the underlying concepts. Thanks!

Help with Custom calculation script in Acrobat 8

Hi all, I am using acrobat 8 on OS 10.5
I am trying to add certain fields (numbers) and then subtract another field value to give an end result.
I don't know anything about Javascript, would anyone be able to help with any info on how I achieve this result? I can only see Add, x and average etc... nothing there for subtraction
Thanks for any help in advance
Swen

This should get you started:
>if (event) {
// get values from two text fields
var a = Number(this.getField('Text1').value);
var b = Number(this.getField('Text2').value);
// subtract the values and show it
this.event.target.value = a - b;
Place this in a 3d text field, as a Custom Calculation Script.

Help with query calculations (recursive)

Hi All,
I want some help with a query using a base rate and the result use in the next calculation year.
Here an example:
create table rate_type(
rate_type_id    number,
rate_desc       nvarchar2(50),
rate_base_year number
insert into rate_type(rate_type_id, rate_desc, rate_base_year) values (1, 'Desc1', 4.6590);
insert into rate_type(rate_type_id, rate_desc, rate_base_year) values (2, 'Desc2', 4.6590);
create table rates (
rate_type_id number
rate_year    number,
rate_value   number
insert into rates(rate_type_id, rate_year, rate_value) values (1, 2012, 1.2);
insert into rates(rate_type_id, rate_year, rate_value) values (1, 2013, 1.3);
insert into rates(rate_type_id, rate_year, rate_value) values (1, 2014, 1.4);
insert into rates(rate_type_id, rate_year, rate_value) values (2, 2012, 1.2);
insert into rates(rate_type_id, rate_year, rate_value) values (2, 2013, 1.3);
insert into rates(rate_type_id, rate_year, rate_value) values (2, 2014, 1.4);The calculation for the first year should be the base rate of the rate type. The next year should use the result of the previous year and so on.
The result of my sample data is:
2012 = 4.659 + 1.2 + 4.659 * (1.2 * 0.01) = 5.9149
2013 = 5.9149 + 1.3 + 5.9149 * (1.3 * 0.01) = 7.1859
2014 = 7.1859 + 1.4 + 7.1859 * (1.4 * 0.01) = 8.4721Query result:
NAME 2012 2013 2014
Desc1 5.9149 7.1859 8.4721
Desc2 XXXX XXX XXXX
How can I do this in one select statement? Any ideas?
Thanks!

URGENT Help With Scientific Calculator!

Hi everybody,
I designed a calculator, and I need help with the rest of the actions. I know I need to use the different Math methods, but I tried tried that and it didn't work. Also, it needs to work as an applet and application, and in the applet, the buttons don't appear in order, how can I fix that?
I will really appreciate your help with this program, I can't get it to work and I'm frustrated, I need to finish this for next Tuesday 16th. Please e-mail me at [email protected].
Below is the code for the calcualtor.
Thanks a lot!

Help with simple script

I was wondering if someone could help me with a simple bit of action script 3. I need to make a movie clip (single_mc) disappear when the user clicks on the mouse (stop_btn). Here’s what I have so far.
function setProperty(event:MouseEvent):void
single_mc.alpha=0;
stop_btn.addEventListener(MouseEvent.CLICK, setProperty);
Also I was wonder if you could recommend an Action script 3 book for me. I would like one that is not a training book, but has situations and then the script written out. For example: I click a button and a movie symbol disappears from the stage. I am a graphic artist, that from time to time, needs simple interaction in flash, but cant justify the time to learn the script.
Thanks for your time

use the snippets panel to help with you with sample code for basic tasks.
function setProperty(event:MouseEvent):void
single_mc.visible=false;
stop_btn.addEventListener(MouseEvent.CLICK, setProperty);

Please help with simple Drag N Drop

I’m desperate and need some help with this simple drag
and drop. Here is the scenario…this animation is for a
kindergarten course. I have 6 different colored teddy bears on the
floor and the bears are to be placed on the middle shelf in the
room, in no particular order. I have the code in place to drag the
bears, and they return to their original location if dropped in the
wrong area. Everything works, except I can’t make the bears
stick to the target area. The target area has to be the same for
all 6 bears. Can someone help me out with this?
I have a feeling that the problem has something to do with my
instance names, but I have tried everything I can think of and
cannot get it to work. Is there some way I can post, send, or
attach my .fla file for someone to look at? I’m desperate.

Help with simple applet - dragging box

I have a picture drawn in the background, but I need to draw a square and resize it when I drag.
So with the picture in the background I click, drag the mouse, and it draws a rectangle from the starting point to where the mouse is while the mouse is clicked.
The only problem is I can't figure out how to do this without redrawing the whole picture. If I don't repaint, it just keeps stretching around rectangles and leaving them there.
I don't really need exact code, just an idea on how to do this without repainting the background every time the mouse is moved (because the picture in the background is complicated to draw and takes like a second).
Thanks
[nvm, found out about xormode]

..the picture in the background is complicated to draw and takes like a second).Paint the 'picture in the background' to a BufferedImage, then when it comes to paint()/paintComponent(), draw the BI to the Graphics object (clipped, if necessary (1)), then draw the rectangle to the Graphics object. This would be further optimised at time of rendering, by drawing both the 'picture in the background' BI and rectangle to a second BI, and finally writing that 2nd BI to the Graphics object.
1) There are potentially other improvements that can be made, particularly with clipping, but I suspect if you try as I suggested, the rendering will be very quick and responsive. I have 40 FPS sound trace animations that do a great deal more on each call to paintComponent(), before bursting the final BI to screen.

Need help with simple XML validation

I am new to Spry and need some help creating a simple
validation. There is a form field which must not contain a value
already in the database. I have a script which accepts a parameter
and returns a boolean result. Here is the XML:
<samples>
<sample>
<ISFOUND>0</ISFOUND>
</sample>
</samples>
1. How do I call this script when the form field changes and
pass the form value as the parameter?
2. How do I check the returned value in the XML and throw an
error if true?
I appreciate any help with this. Please let me know if there
is a better way to achieve the same result.
Thanks,
Rich

I enabled the call to the XML response. However, I am having
trouble identifying when the call is complete so I can parse the
result. How do I run my check after the data load and display the
proper message?

Beginner needs help with simple code.

I just statrted learnind java, and I need some help with this simple program. For some reason everytime I enter my Farenheit value, the Celsius conversion returns as 0.0. Would really appreciate the help. Thanks.
Here's the code:
public class TempConverter
public static void main(String[] args)
double F = Double.parseDouble(args[0]);
System.out.println("Temperature in Farenheit is: " + F);
double C = 5 / 9;
C *= (F - 32);
System.out.println("Temperature in Celsius is: " + C);
}

double C = 5 / 9This considers "5" and "9" to be integers and does an integer division, discarding the remainder. The result of that division is 0. Trydouble C = 5.0/9.0;

Help with Auto calculations

I have an existing pdf that i am trying to edit and make it more functional...i.e. fillable info with auto calculations of cost based on a given number (times a specific cost)
Example on the form....
Car Registrations (per car) _____ X $25 _________
The first line above is # Cars Registered
The last line is Total Cost
The blank lines above i have added a text box to for auto calculations. I have formated these boxes as numbers (first line) and dollar value total (second line)
I've added another text box for the $25 and placed it overtop the worded one. I've locked this box and the total box. I've calculated the product of the total box by linking it to the first line and the $25 to give the total cost...
Problem is, it isnt working....the total box isn't seeing the $25 to give a proper calc. Whatever number i place in the first line, only zero shows in the total.
I'm obviously missing something....been at this for two days....frustrated. I have many more inputs like this on the form, and eventually want all the totals to provide sub totals and a grand total. I understand how this all works to a degree, doesnt seem that difficult, but i have to be missing something.
I even tried re-creating the document in word, input to adobe, make a new form, let the system recoginize areas as fillable, etc, etc, etc. When i get to the calculations portion, same result...there are not many tutorials out there on this...sadly

Help with Javascript/Calculations

Hello,
Have a building use policy for school.
Need help with checkboxes and default values. I can get javascript/math to work when I click check box.
Someone wants to rent a room they check the rentRoom checkbox. Then the enter how many rooms 1,2,3 etc.. The value for the rentRoom checkbox is $25.
I can get it when the checkbox for rentRoom is selected the rentRoom.Total computes correctly. However, what I want is when the form opens up a default value of $0.00 to be in there. I also want if someone goes back and unchecks the rentRoom checkbox the value goes back to $0.00 not just blank. Right now I am getting the error the value entered does not match the value of the field. That is if I put the default value in options. Basically, I can't seem to figure out the javascript code to get this to work.
Am I asking for too much, can someone guide me to javascript to help me out.
I have tried if/then statements and switch statements. I just can't figure out how to get it to for lack of better a word - toggle back and forth.
If this is not possible please tell me. If it is too complicated tell me. I am not using livecycle for this as we had a word document and I just used the find form fields. I am also using Adobe Acrobat 8 Professional.
Thanks

Hello,
Thanks that looks good. I am still missing something but the calc doesn't work when I put in my variables. I will work with it more but nothing happens.
The one thing is I have the default value of the checkbox as 15 so don't know if that messes it up.
Right now I get the default value of $0.00 all the time. When I click on the check box on/off it doesn't do the calcs.
sorry, any more input, what am i missing??
I also changed the syntax error that was posted on your origianl post. You had == 'Off" I changed that to 'Off'

Help with "simple" JFileChooser problem...

Hi all,
how do I set the font in a JFileChooser???
I have tried everything, but it always uses the Look & Feels default font setting. Can I change the default Look&Feels font setting?
Greatfully for any suggestions!
Cheers
Anders ;-D

Hello!
You can use the UIManager, e.g. UIManager.put("FileChooser.font", new Font("Arial",
Font.BOLD, 14);
Well, that didn't seem to help with my case either. So I tried something else: I overrided all of the defaults by using UIManager.put(key, value) this way I got all of the Fonts in the JFileChooser to change.
Correct me if I'm wrong... ;)
- Cathra -
Sample Code that performs the requested:
// Prepare the resources
FontUIResource font12Arial = new FontUIResource( "Arial", Font.PLAIN, 12 );
// Put values into UIDefaults (before initializing the JFileChooser)
UIManager.put( "ToolTip.font", font12Arial );
UIManager.put( "OptionPane.messageFont", font12Arial );
// shown for example
UIManager.put("FileChooser.openButtonText", "OpenUp");
UIManager.put("Button.font", font12Arial);
UIManager.put("Label.font", font12Arial);
UIManager.put("Table.font", font12Arial);
UIManager.put("TextField.font", font12Arial);
UIManager.put("ScrollPane.font", font12Arial);
UIManager.put("ComboBox.font", font12Arial);
UIManager.put("CheckBox.font", font12Arial);
UIManager.put("TitledBorder.font", font12Arial);
UIManager.put("RadioButton.font", font12Arial);
UIManager.put("ToolTip.font", font12Arial);
UIManager.put("TextPane.font", font12Arial);
UIManager.put("TextArea.font", font12Arial);
UIManager.put("Tree.font", font12Arial);
UIManager.put("List.font", font12Arial);
UIManager.put("MenuBar.font", font12Arial);
UIManager.put("Menu.font", font12Arial);
UIManager.put("MenuItem.font", font12Arial);
UIManager.put("TableHeader.font", font12Arial);
UIManager.put("TabbedPane.font", font12Arial);
// somewhere in the code:
JFileChooser c = new JFileChooser();
c.showOpenDialog(aParentFrame);
