Sum in Acrobat doubles
At work I use Adobe Acrobat Professional 7.0 and I've created a form with several fields that I have used Calculate Sum. It works fine except that the totals consistantly double. I've used this in other fillable PDF's in the past with success and I don't know what I'm doing wrong. Nothing else is adding in from other fields and it looks like a straight sum to me. Any ideas?
If you have named your fields in a hierarchal manner, text.1, text.2, etc., then you either have to select the top level field name or the individual field names but not both.

Having issue with a Sum/Average program
The issue I get when I run the command is, let's say I enter 4 numbers, 5, 7, 9, 16 then enter a 0 to end the count, the avg it gives me is 8.0 instead of the 9.25 it should be. Any insight would be greatly appreciated.
import java.util.Scanner;
public class StephenVanoverSumAverage
public static void main(String[] args)
Scanner keyboard = new Scanner(System.in);
double count = 0.0;
double sum = 0.0;
double num;
System.out.println("Enter a number (Type 0 to quit): ");
num = keyboard.nextInt();
while ( num !=0 )
System.out.println("Enter a number (Type 0 to quit): ");
num = keyboard.nextInt();
sum += num;
count++;
double average = sum / count;
System.out.printf("Average is " + average);
}Not quite, since the first number is discarded. The zero is included in the sum, but the first number entered is not. The count is incremented for the zero, true, but I think that is not the problem.
Still, the code could be cleaner with respect to both when the count is incremented, and what numbers are included in the sum.

Acrobat X intermittently won't launch, multiple Acrobat.exe processes hanging in task manager
Apologies if this is in the wrong community area - I was unsure where it belongs.
This is an intermittent issue, but does happen several times a day.
Regardless of what method is used to launch Acrobat (double-clicking a PDF, clicking the shortcut in the taskbar, selecting Acrobat from the start menu), often the application won't launch. Upon investigation, task manager shows multiple instances of Acrobat.exe, although the application is not running (see the image below). Ending all Acrobat.exe processes does allow Acrobat to launch.
Any thoughts as to what might be causing this, as well as a more permanent fix? The workaround of constantly ending multiple processes is becoming cumbersome.
We are running Acrobat X Pro in Windows 7. I also have several CC 2014 apps installed (as well as a couple of earlier versions required for plugin functionality).This happens all the time in my company with several installs of Acrobat.
The only way to fix this for us is to end each process in Task Manager as you have pointed out.
It is very time consuming in our workflow as we each operator deals with hundreds of PDFs daily, and has to do this End Process procedure several times a day.
We have done several tests and nothing seems to stop this from happening. -
Need help returning (not printing) avg GPA from array??
Here's what I have so far. After returning the value then I gotta print the avg in a separate method. I also need to check the names of the first and last student using an "equals" method. Please someone help with whatever you can. Here's what I got:

return avg;Oh no I wasn't giving any orders. I was saying I have been trying to edit what I have, but I can't figure out how to get the method right to do my average of the GPA from the loop. I don't know what to put in there. I was just asking if you would write it and then kind of explain what u did for me please.

How to change the date format of footer from dd/mm/yyyy to Monday 09 August 2010 when we down load the report in pdf file
Hi,
Revenue is a sample column. You can pull any measure column used in the report.
And put this formula in a separate new column. And in the narrative view use this column number.For Ex- if the number of the column in the criteria is 15, then mention @15 in the narrative view.
NOTE-Rows to display in narrative view should be set to 1.
And in the formula-CEILING(CAST(COUNT("F1 Revenue"."1-01 Revenue (Sum All)") as DOUBLE)/ 25)
25 refers to the number of row count to display. You can define the number according to your requirement.

Read multiple files and save all into one output file(AGAIN)
Hi, guys
I need your help for reading data from multiple files and save the results into one output file. When files are selected from file chooser, my program read the data line by line , do some calculations and save the result into the output.

Sorry about the long lines.
As you can see, all input files saved in array called files, however when OpenFile1() function is called, it take input (fileName_in) as a single file not an array. I'm assuming this causes the exception.
When there's muptiple inputs, program should take each file from getFileName() to outputToFile() sequentially.
Does anybody have an idea to solve this?
Thanks a lot!!you naming convention is confussing. you should follows Java naming convention..you have a getXXX but decalred the return type as "void"...get usully means to return something...
your code is doing too much..and hard to follows..
1. get the selected files
for each selected file
process the file and return the result
write out the result.
/** close the precious resource */
public void closeResource(Reader in){
if (in != null){
try{ in.close(); }
catch (Exception e){}

return lineCount;
finally{ closeResource (in); }

BufferedReader in = null;
StringBuffer result = new StringBuffer();
try{
in = new BufferedReader(new FileReader(inFile));
String line = null;
while ((in.readLine() != null){
.. do something with the line
result.append(....);
writeToFile(outFile, result.toString());
finally{ closeResource (in); }
public void writeToFile(File outFile, String result) throws IOException{
PrintWriter out = null;

out = new PrintWriter(new FileWriter(outFile, true)); // true for appending to the end of the file
out.println(result);

Creating a PDF from a database
Hi all I hope somebody could help here as I have been around
and around trying to work this out
Problem: PDF creation from a database
I have a database which has all the text information to
create a PDF.
All images are from the web and are not stored locally web
serve on a server
Goal:
To create a viewable PDF on the fly from the database when a
user clicks on a link.
bring in the picture and relevant information then insert a
header and footer
Dose anybody have any php scripts that could achieve the
final result effort less
when writing this it just popped into my head , could I call
a web page into the PDF
if so howNo that won`t work. AlivePDF uses its own method of embedding fonts (if I remmeber correct you can only use ttf not otf font formats). AlivePDF is not exactly well documented or much used. Its technics are a little "arcane". It was created by the same Guy whose brainchild was Stage3D so you can imagine how complex it is for us mere mortals. A good start is this little blog .
I also can see why Adobe (who is his boss) isn`t exactly highly motivated to make AlivePDF too much of a Acrobat Double ;-) -

Missing method body or declare abstract...
Hi There,
Im working on an assignment that works with the math class and performs a bunch of mathematical functions. Im trying to declare the different fields in the math class and I keep getting error messages!!
This is what I have right now
public class Math
// Returns the absolute value of a double value.
double abs(double a);
// Returns the absolute value of a int value.
int abs(int a);
//Returns the greater of two double values.
double max(double a, double b);

int max(int a, int b);
// Returns the lesser of two double values.
double min(double a, double b);
// Returns the lesser of two double values.
int min( int a, int b);
// Returns the value of the first argument raised to the power of
// the second argument.
double pow(double a, double b);
// Returns the remainder of division of two integers.
int remainder(int a, int b);
// Returns the closest long to the argument.
long round(double a);
// Returns the sum of all the elements in an array of doubles.
double sum(double [] doubleArr);
// Returns the sum of all the elements in an array of ints.

// Storage for the list of doubles to be used double sum method.
private double [] doubleArray = {5.25, 10.00, 14.50, 21.90};
}When I try and compile it tells me that Im missing method body or declare abstract.
I originally had this
// Returns the absolute value of a double value.
double abs;
// Returns the absolute value of a int value.
int abs;
//Returns the greater of two double values.
double max;
//Returns the greater of two int values.

int remainder;
// Returns the closest long to the argument.
long round;
// Returns the sum of all the elements in an array of doubles.

// Returns the sum of all the elements in an array of ints.
int sum(int [] intArr);
// Storage for the list of integers used for the int sum method.
private int [] intArray = {5, 10, 15, 20};
// Storage for the list of doubles to be used double sum method.
private double [] doubleArray = {5.25, 10.00, 14.50, 21.90};When i tried doing this it told me that I had already declared the field previously when it got the the field with the same name and thats why I added the bit in brackets.....
Im so lost... can anybody hep????hi,
here is your code...
modified by correcting my bad habit...
he..he...
public class Math
// Returns the absolute value of a double value.
double abs(double a){return 0.0;}
// Returns the absolute value of a int value.
int abs(int a){return 0;}
//Returns the greater of two double values.

I've been trying to fill out forms for school on adobe reader x.
The form has last name then first name, etc.
Well, when I type my last name into the box, it also puts it into the first name box.
And when I erase my last name from the first name box, it also erases it from the last name box.
I've tried everything I can think of and it's really beginning to get aggravating.Assuming the document doesn't have security restrictions that would prevent it, you can use the Select Object tool (left-pointing black arrow) in Acrobat, double-click either of the fields, and rename it so it is unique in the form.

Why won't my number enter in the other box
I am writing a program for class. I have to be able to input a number in a box and then have it display in the box next to it. It also has to add the numbers everytime I put a number in the first box. I am able to get the enter button to change colors. Not sure how to get it to add and display the numbers. Also the first box has to default back to 00.0 when I click enter. Hope this is clear. Here is the code.

}I still cannot seem to get the boxes on the right to
accept the numbers I am putting in on the left. What
can I do to correct this? Please help. Thank you.You should put some code into your ActionListener to call setText on the boxes on the right. At present you don't have any, except something that is commented out.
Here's a couple of other problems, too:if (e.getActionCommand().equals ("ENTER"));First of all, that if-condition will never be true because none of your buttons have "ENTER" as their text. Several of them have "Enter" but that isn't the same thing. Even if you got the case right, this would still be a problem because you wouldn't know which button had been pressed. And finally, even if the if-condition is true, nothing will happen because you have a semi-colon at the end of it, which says "do nothing".
If you must have a single ActionListener for all those buttons, and it needs to distinguish which button was pressed, then code like this:if (e.getSource() == myButton2)will do that. However you would have to change your code to make myButton2 (etc.) instance variables of the class and not just local variables in the constructor, as they are now. -
Writing a program that uses menu options of ADD, SUBTRACT, MULTIPLY, and DIVIDE.
The user enters a number in a field labeled "Number 1" then enters a number in a field labeled "Number 2". The final field is labeled "Result"
Each of the menu options has an ActionEvent.
I'm having trouble with how to get the fields for Number 1 and Number 2 to display in the Result field when the user selects one of the menu options.
Here is the code with an ActionEvent started for "Add" but not finished since I neeed some advice from this point on....
Please disregard the other menu options, at this point I am just working on the math portion...
Cheers!

It allows only specified characters to be entered and beeps for illegal characters. If you still want a message dialog you can add it in the document filter class with (or in place of) the Toolkit..beep call.
I also changed the variable result to a double and added a NumberFormat to allow formatting to only one decimal place for fractions (as a result of division) in resultField.
I gave a choice of YES_NO vs. YES_NO_CANCEL options in the exit dialog.

How can I uninstall old versions of Adobe Illustrator?
How can I uninstall old versions of Adobe Illustrator?
This is for uninstalling CS2, but you might find it helpful. EDITED: but watch out, since I don't know if trashing any of these will remove currently needed Illustrator files, if you have a later version.
To uninstall Adobe Creative Suite in Mac OS 1 -- Double-click Activity Monitor.app in Applications/Utilities, select AHCRemind, and click Quit Process.
2 -- If you intend to install the product on a different computer, transfer the activation. (See “To transfer the product activation” on page 1.)
3 -- If you want to uninstall Adobe Acrobat, double-click the uninstaller in Applications/Adobe Acrobat 7.0 Professional, and follow the on-screen instructions.
4 -- If you want to uninstall Version Cue 2, double-click the uninstaller in Applications/Adobe VersionCue CS2, and follow the on-screen instructions.
Note: If the Version Cue uninstaller fails, see the alternative procecure, “To remove Version Cue manually” on page 4.
5 -- From the Applications folder, drag the following items, if present, to the trash: Note: After you drag the items to the trash in steps 5-8, you must empty the trash before you can reinstall
Adobe Creative Suite 2 on the same computer. • Adobe Acrobat 7.0 Professional • Adobe VersionCue CS2 • Adobe Bridge
• Adobe GoLive CS2 • Adobe Illustrator CS2 • Adobe InDesign CS2 • Adobe Photoshop CS2 • AdobeHelpCenter.app
6 -- From the Utilities folder, drag the following items, if present, to the trash: • Adobe Utilities • Adobe Updater.app
7 -- From the Library folder, drag the following items, if present, to the trash: • Application Support/Adobe/AdobeHelpData • Application Support/Adobe/Assistance • Application Support/Adobe/StartupScripts/Workflow Automation Scripts
• Preferences/Adobe/Workflow • Preferences/com.adobe.ActivationUtility.plist • Preferences/com.adobe.GoLive.plist • Preferences/Adobe Save For Web GL 8.0 Prefs
8 -- From the Users/[user name] folder, drag the following items, if present, to the trash: • Library/Preferences Panes/Opera Preferences
• Library/Caches/Opera Cache
• Documents/AdobeStockPhotos
To remove Version Cue manually (Mac OS only, not recommended)
If you’ve accidentally removed parts of the Version Cue installation manually or if the uninstaller fails, you have to remove the remaining installed Version Cue components manually.
1 -- From the Library/PreferencePanes folder, drag the Version Cue CS2.prefPane folder to the trash. 2 -- From the Library/Preferences folder, drag the com.adobe.versioncueCS2.plist file to the trash. 3 -- From the Library/StartupItems folder, drag the AdobeVersionCueCS2 folder to the trash. 4 -- From the Applications folder, drag the Adobe Version Cue CS2 folder to the trash.
5 -- From [user home]/Library/Preferences/Adobe, drag the Workflow folder to the trash. 6 -- (Optional) From the [user home]/Documents folder, drag the Version Cue folder to the trash. -
How to use javascript in visual jsf
I have a web project and I am using visual jsf in netbeans. My problem is I cannot with javasciprt.
When I clicked to a button I want to make some check with javascipt and then run server side java code. With jsp I used to add onclick javascipt and if it is ok, I just submit to servlet and run the java code in servlet. How can I do this with visual jsfIf you are trying to display total number of pages in a report, Add the below formula in the column of the report and hide that column in the report.
FX = sum(count(1))/25
You can then reference the column in the narrative view like this: "Total pages in the report are @5" and out put may be "Total Pages in the report are 30".
Or
You can also use something like the below:
To calculate them use fi:
CEILING(CAST(RCOUNT("FactColumn In the Report (Sum All)") as DOUBLE)/ 25) for the page number
CEILING(CAST(COUNT("FactColumn In the Report (Sum All)") as DOUBLE)/ 25) for the total pages
Put the above formula in the column and reference it in the narrative view like I mentioned in the previous example.
If you are report view is pivot, then please refer to this link: http://oraclebizint.wordpress.com/2008/01/17/oracle-bi-101332-pagination-in-pivot-tables/
Hope this helps.
Thanks,

My model never saves changes of the query settings 'Maximum rows' and 'Suppress sum'. Every time I reopen my model the settings have the initial values '500' and ' '. For me it seems to be a bug.
Thanks for reporting this issue. It has been fixed and you will be able to see this fix in the next service pack.
Since, this issue is related to obsolete parameters, I believe, not having the fix immediately should not affect the operatability of your Visual Composer installation. In the meantime, you may employ a workaround as described below:
To change the values of maxrows and suppress sum fields:
1. double click on the query infoactor on the story board
2. on the side pane, you should see the properties of the query, the properties including maxrows and supress sum.
3. Make any change in the "Name" property. The save button should turn active.
4. Now make necessary changes in the values of maxrows and suppress sum.
5. Save.
