Help with double and float

I added the (float) after the = in both and it fixed the top and not the bottom. "cant convert double to float" (as well as the answer to this, if somone could correct my terminology as well it would be appretiated. thanks in advance)
float torontoF = (float)(torontoC * 1.8) + 32;
     System.out.print (torontoF);
x      float stockholmC = (float)(stockholmF ? 32)* .5556;
     System.out.print (stockholmF);

Help with doubles and intergers

I'm new to JAVA programing. So, I'm hoping that someone can help me. Below is part of my code that I'm having a problem with.
int gold, total
double percent
percent = ((gold / total) * 100)
comes out looking like 0.0
Is there a way to define (gold / total) as a double in the math statement?
Thank you for all your help,
Jennifer

The problem is integer division always produces an integer, so for example:
1 / 2 == 0, not 0.5
but:
((double) 1) / 2 == (approximately, allowing for IEEE floating point precision errors) 0.5
same for 1 / ((double) 2) or using literal constants like 1.0 / 2

I need help with CSS and floating

Okay, I know I need to get up on CSS and get rid of tables in
my sites.
However, I'm running up against a problem, and after banging
my head
against it for a while, I realize I need help. I've stripped
this down
so as to only show the area where I'm having difficulty.
What I want is a page that has everything down the center,
taking up no
more than 750 pixels and no more than 550 pixels of width. No
problem there.
After the header and the top content, I'd like to have two
"columns",
each in it's own separately-colored box. I would like the
right-side
column/box to be a static size, while the left-side
column/box sizes
dynamically.
Where I'm having problems is that when one column is boxed,
it's fine,
but whenever I wrap each column in its own box, the
fixed-size box
either jumps below or above the other box (depending on which
one has
been floated and which order the div's appear in the code).
Here are the links:
CSS:
http://www.afice.org/stylesheet/floatmestyles.css
ex 1:
http://www.afice.org/floatme1.html
ex 2:
http://www.afice.org/floatme2.html
Before sending, I took a look again, just to see if I was
missing
anything. I did notice that it doesn't seem to be that the
box is
jumping down so much as it is that it's getting written over.
Anyway, sorry for the long-winded explanation. I hope I've
managed to
explain what I'm trying to do well enough that someone can
tell me where
I'm going wrong.
Thanks,
--Kevin

Do you want something like this:
http://www.pmob.co.uk/temp/spointfooter.htm
You will need to look at the code to see how it was done.
Otherwise, there are different examples here on Pauls' site:

Help needed with doubles and integers

I just want to start telling all you that you have been a big help to me the last couple of months. Now, for my issue. I'm having a problem doing some work with doubles and integers. Below is the code I've tried. But, I keep getting mismatch types. I need num3 to fill in a JTextField by the end with the answer for the calc. Num2 is fill in from a JTextField with a double.
Int num1 = 0, num4 = 0, num3 = 0;
double num2 = 0, totint = 0;
for(count = 0; num4 < count; count++)
totint = (1 + num2);
System.out.println(totint);
num3 = double (num1 * totint);
String k = Integer.toString(num3);
tf3.setText(k); (This is a JTextField)
Test data
num1 = 10000
num2 = 3.4
num4 = 4
num3 = the value from the calc

First of all, your for loop is never going to run.
for (count = 0; num4<count; count++)
totint = (1 + num2);
System.out.println(totint);
num4 = 4 and will not be less than count, so the for loop will not be executed.
Second, what exactly are you trying to accomplish here. The way you have your code set up, the for loop (if it were to execute) would print out 4.4 each time it passes, then do the calculation. You may need to rethink your objective.

Help with writing and retrieving data from a table field with type "LCHR"

Hi Experts,
I need help with writing and reading data from a database table field which has a type of "LCHR". I have given an example of the original code but don't know what to change it to in order to fix it and still read in the original data that's stored in the LCHR field.
Basically we have two Function modules, one that saves list data to a database table and one that reads in this data. Both Function modules have an identicle table which has an array of fields from type INT4, CHAR, and type P. The INT4 field is the first one.
Incidentally this worked in the 4.7 non-unicode system but is now dumping in the new ECC6 Unicode system.
Thanks in advance,
C
SAVING THE LIST DATA TO DB
DATA: L_WA(800).
LOOP AT T_TAB into L_WA.
ZDBTAB-DATALEN = STRLEN( L_WA ).
MOVE: L_WA to ZDBTAB-RAWDATA.
ZDBTAB-LINENUM = SY-TABIX.
INSERT ZDBTAB.
READING THE DATA FROM DB
DATA: BEGIN OF T_DATA,
             SEQNR type ZDBTAB-LINENUM,
             DATA type ZDBTAB-RAWDATA,
           END OF T_TAB.
Select the data.
SELECT linenum rawdata from ZDBTAB into table T_DATA
     WHERE repid = w_repname
     AND rundate = w_rundate
     ORDER BY linenum.
Populate calling Internal Table.
LOOP AT T-DATA.
APPEND T_DATA to T_TAB.
ENDLOOP.

Hi Anuj,
The unicode flag is active.
When I run our report and then to try and save the list data a dump is happening at the following point
LOOP AT T_TAB into L_WA.
As I say, T_TAB consists of different fields and field types whereas L_WA is CHAR 800. The dump mentions UC_OBJECTS_NOT_CONVERTIBLE
When I try to load a saved list the dump is happening at the following point
APPEND T_DATA-RAWDATA to T_TAB.
T_DATA-RAWDATA is type LCHR and T_TAB consists of different fields and field types.
In both examples the dumps mention UC_OBJECTS_NOT_CONVERTIBLE

Help with count and sum query

Hi I am using oracle 10g. Trying to aggregate duplicate count records. I have so far:
SELECT 'ST' LEDGER,
CASE
WHEN c.Category = 'E' THEN 'Headcount Exempt'
ELSE 'Headcount Non-Exempt'
END
ACCOUNTS,
CASE WHEN a.COMPANY = 'ZEE' THEN 'OH' ELSE 'NA' END MARKET,
'MARCH_12' AS PERIOD,
COUNT (a.empl_id) head_count
FROM essbase.employee_pubinfo a
LEFT OUTER JOIN MMS_DIST_COPY b
ON a.cost_ctr = TRIM (b.bu)
INNER JOIN MMS_GL_PAY_GROUPS c
ON a.pay_group = c.group_code
WHERE a.employee_status IN ('A', 'L', 'P', 'S')
AND FISCAL_YEAR = '2012'
AND FISCAL_MONTH = 'MARCH'
GROUP BY a.company,
b.district,
a.cost_ctr,
c.category,
a.fiscal_month,
a.fiscal_year;
which gives me same rows with different head_counts. I am trying to combine the same rows as a total (one record). Do I use a subquery?

Hi,
Whenever you have a problem, please post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) from all tables involved.
Also post the results you want from that data, and an explanation of how you get those results from that data, with specific examples.

I am trying to combine the same rows as a total (one record). Do I use a subquery?Maybe. It's more likely that you need a different GROUP BY clause, since the GROUP BY clause determines how many rows of output there will be. I'll be able to say more after you post the sample data, results, and explanation.
You may want both a sub-query and a different GROUP BY clause. For example:
WITH    got_group_by_columns     AS
     SELECT a.empl_id
     ,     CASE
                    WHEN c.category = 'E'
              THEN 'Headcount Exempt'
                    ELSE 'Headcount Non-Exempt'
            END          AS accounts
     ,      CASE
                    WHEN a.company = 'ZEE'
                    THEN 'OH'
                    ELSE 'NA'
            END          AS market
     FROM              essbase.employee_pubinfo a
     LEFT OUTER JOIN mms_dist_copy             b ON   a.cost_ctr     = TRIM (b.bu)
     INNER JOIN       mms_gl_pay_groups        c ON   a.pay_group      = c.group_code
     WHERE     a.employee_status     IN ('A', 'L', 'P', 'S')
     AND        fiscal_year           = '2012'
     AND        fiscal_month          = 'MARCH'
SELECT    'ST'               AS ledger
,       accounts
,       market
,       'MARCH_12'          AS period
,       COUNT (empl_id)      AS head_count
FROM       got_group_by_columns
GROUP BY accounts
,            market
;But that's just a wild guess.
You said you wanted "Help with count and sum". I see the COUNT, but what do you want with SUM? No doubt this will be clearer after you post the sample data and results.

1) Swing related questions should be posted in the Swing forum.
Custom painting should be done in the paintComponent(..) method. You created a "pintarGraphico" method to do the custom painting, but that method is only execute once. When Java determines that the panel needs to be repainted, the paintComponent() method is executed which simply does a super.paintComponent(), which in turn simply paints the background of the panel overwriting you custom painting.

What's the problem you're having ???

Help with Title and Author Displaying on the iBooks Bookshelf.

I have created a book using iBooks Author and connected my iPad to my iMac to Preview my book, the book previews correctly the information I have entered into iBooks Author, however when you look on the iBooks Bookshelf it says UNKNOWN TITLE and UNKNOWN ARTIST even though I have entered this on my title page in iBooks Author, however the icon of my book on the iBooks Bookshelf is showing correctly the photo on the cover and the title and author, can any one help with this please?
Also no Category is showing against my book onthe iBooks Bookshelf how do I add one please?

To be honest, you should really put this under a seperate post of your own, but I'm not here to whine...
It sounds that you haven't defined the book title yet.
Open your book in iBooks Author and go to the panel on the left-hand side of your screen that shows your page thumbnails. Scroll to the top of this box, and find the panel that has the:
Book Title
Intro media
Table of contents
Glossary.
If your Book Title here says simply 'Book Title', then define it by double-clicking on the 'Book Title' text in the thumnails panel, and type in your book's title.
HTH.

Help with WRT54G and CenturyTel DSL

I'm hoping someone can help me out. I'm trying to set up a WRT54G with DSL service from Century Telephone.
I'm running Windows XP and have been using this DSL service for several years without a router, so I know I can connect reliably. I've connected my desktop directly to the router (e.g. wired connection) and I've double and triple checked connections and know they are secure and correct.
I ran the setup CD, and it could not find an Internet connection. I went through all the normal steps - powering down everything, restarting. No dice. I downloaded Easty Answer ID 2210 from Linksys about setting up PPPoE DSL connections and followed all instructions - still no luck. I downloaded latest firmware for router, tried again - no luck. When I check router's status page, I see no connection and get error message "Cannot get IP address from PPPoE server".
Then contacted CentryTel tech service to see if they had any suggestions. They helped me set up a bridge connection through the router - but that just demonstrates the Internet conneciton is available and there isn't a wiring problem. Spent about an hour on line with Linksys tech support, but he wasn't able to diagnose the problem and then the connection was dropped on his end.
Does anyone have any suggestions?
Thanks.
Mark

It is so nice to read that others are having the same problems - misery loves company.
I used to have Comcast, but moved and switched to DSL. I have never had problems like the ones I have experienced since switching, and have not had luck with either CenturyTel or Linksys customer service.
I have the same issue - so we fiddled with the IP address and were able to get one computer on wireless. However, we have three computers in the house - but the other two can't get on the Internet wirelessly. Can multiple computers use the wireless connection after you've changed the IP address for one? It doesn't seem to work for us, despite multiple calls to help desks (Linksys told us it was a problem with our laptop maker; however, we never had issues with this particular computer going on wireless at the old house.)
Any help for WRT54TG/CenturyTel (or any DSL)/multiple computers is greatly appreciated!
Thanks!

Please Please help with JavaScript and Actions

Hello!
Is there a way to perform a saved Action from the Action Pallette using a JavaScript script? I know there is a way to do it with Visual Basic.
Is there a way to run a Visual Basic script from a JavaScript script?(which could be a potential workaround if JavaScript CANNOT call on an Action)
Is there a way to call on a JavaScript from an Action?
Here's specific information on my problem:
I am using Illustrator CS2 on a PC
I have written all of the JavaScript scripts that I need to perform various layer selection procedures and they all work perfectly. I have placed them in the Presets > Scripts folder so that they appear in my file menu.
I wrote a very long action that called on these scripts (using Insert Menu Item > then selecting the script by going File > Scripts) sequentially and did some selecting and copy-pasting and applying graphic styles in between scripts. The Action worked PERFECTLY and ran all the scripts I needed to an automated a process that usually takes me an hour in less than five minutes!
I saved the actions and saved the file.
After closing Illustrator all of the lines of the action that called on scripts disappeared! It seems this is a known bug...I currently know of no workaround.
Can anyone help with any of the following things:
1. Getting actions to SAVE the commands to run javascripts
2. Writing a JavaScript that runs an Illustrator Action
3. Writing a JavaScript that runs a Visual Basic script that runs an Illustrator Action.
I spent three days learning the basics of JavaScript (mostly by trial and error) and successfully wrote all the scripts I needed...I was overjoyed! But now that I've closed illustrator my actions to run said scripts do not work. PLEASE ADVISE!!!
Thanks in advance,
Matthew

try next
1)if possible split JS-code into 2 parts (before/after action)
2)make vbs script with contents
Set appRef = CreateObject("Illustrator.Application.3")
appRef.DoJavaScriptFile("C:\my1.js")
appRef.DoScript(Action As String, From As String)
'add wait while ActionIsRunning
appRef.DoJavaScriptFile("C:\my2.js")
3) run vbs (File > Scripts or double-click).

Need help with JFormattedTextField and DocumentListener

I can't get my JTextField to work with my DocumentListener. I'm very new to Java so the solution might be quite simple. Any help is very appreciated!
Here is my complete code:

import javax.swing.JFormattedTextField.AbstractFormatter;

public class Test extends JFrame {
private JFormattedTextField eingabeFeld;
private JFormattedTextField ausgabeFeld;
private String eingabe;
private String ausgabe;
public Test() {
     super("DocumentListener-Test");
     NumberFormatter textFormatter = new NumberFormatter(new DecimalFormat("###,##0.0#"));
     textFormatter.setCommitsOnValidEdit(true);
     textFormatter.setAllowsInvalid(false);
     DefaultFormatterFactory fmtFactory = new DefaultFormatterFactory(textFormatter);
     EingabeListener eingabeListener = new EingabeListener();
     JFormattedTextField eingabeFeld = new JFormattedTextField();
     eingabeFeld.getDocument().addDocumentListener(eingabeListener);
     eingabeFeld.getDocument().putProperty("name", "EingabeFeld");
     eingabeFeld.setFormatterFactory(fmtFactory);
     AbstractFormatter formatter = eingabeFeld.getFormatter();
     JFormattedTextField ausgabeFeld = new JFormattedTextField();
     ausgabeFeld.setEditable(false);
     // this is not needed!
     //ausgabeFeld.getDocument().addDocumentListener(eingabeListener);
     //ausgabeFeld.getDocument().putProperty("name", "AusgabeFeld");
     //ausgabeFeld.setText("1");
     JPanel contentPane = new JPanel();
     GridBagLayout gridbag = new GridBagLayout();
     GridBagConstraints c = new GridBagConstraints();
     contentPane.setLayout(gridbag);
     c.gridx = 0;
     c.gridy = 0;
     c.ipadx = 200;
     gridbag.setConstraints(eingabeFeld, c);
     contentPane.add(eingabeFeld);
     c.gridx = 0;
     c.gridy = 1;
     c.ipadx = 200;
     gridbag.setConstraints(ausgabeFeld, c);
     contentPane.add(ausgabeFeld);
     setContentPane(contentPane);
class EingabeListener implements DocumentListener {
     public void insertUpdate(DocumentEvent e) {
          Calculate(e);
     public void removeUpdate(DocumentEvent e) {
          Calculate(e);
     public void changedUpdate(DocumentEvent e) {
     private void Calculate(DocumentEvent e) {
          // this does not work!
          //eingabe = eingabeFeld.getText();
          //double wert = Double.parseDouble(eingabe);
          //wert = wert/2;
          //ausgabe = Double.toString(wert);
          //ausgabeFeld.setText(eingabe);
public static void main(String[] args) {
     final Test frame = new Test();
     frame.addWindowListener(new WindowAdapter() {
          public void windowClosing(WindowEvent e) {
               System.exit(0);
     frame.pack();
     frame.setVisible(true);
}

Thanks that worked! Now I changed
JFormattedTextField ausgabeFeld = new JFormattedTextField(); to
ausgabeFeld = new JFormattedTextField(); as well.
I changed eingabe, ausgabe from String to Object and .getText and .setText into .getValue and .setValue. I also added ausgabeFeld.setFormatterFactory(fmtFactory);
AbstractFormatter formatteraus = ausgabeFeld.getFormatter();
But now I have the probelm, that I don't know how to parse the eingabe Object into a double and back to be able to calculate with it.
And another problem is, that the ausgabeFeld get's only updated and the eingabeFeld formatted if the eingabeFeld loses focus.
I hope anybody can help me with these problems now! Thanks in advance.
