I have never worked with Java coding and am in need of assistance for an acrobat form I am working on.
- I have a form with a field identifier called BACompnayName (this is the field where they would enter their company name).
- I then have a form field with two radials that says "Is the shipping address the same as the business Address" - "Yes" and "No" (the form identified for this field is SASame.
What I am trying to accomplish:
- If they click yes, I would like the form to fill in the information found in BACompanyName otherwise, leave it blank to be filled out by the person filling out the form.
I appreciate any help.
Thanks,
BrettSomething like the following?

How to write Java script for refering the 1st page text field from 2nd page?
Hello I am developing an VISITOR info interactive form with webdynpro ABAP, its with 2 pages. Their heirarchy is,
VISITOR_form

Now, i have selected the 'Text_Field_B_1' of page_2 and writing the Java script, my requirement is; If Page_1's 'Text_Field_A_2' has a value of "Value_ABCD", THEN the 'Text_Field_B_1' of page_2 should be 'readOnly'. Pls let me know Wht is the Java script for this requirement?if (xfa.event.newText=="ABCD")

How do I pass an error status from my java code back to the Program Job Ser
How do I pass an error status from my java code back to the Program Job Server?
I have a jar program object that reports a scheduled status of "Success" even if the java code errors out.Exceptions thrown from the program object are ignored by the program job server.
You need to configure the Program Object, then stream out a special string sequence to the stdout of the Program Object, to set the scheduled instance status to Failed.
Look up SAP KBase 1201804 - How to programmatically set the status of a Program object to "Failed"

How to write a code for open new txt file in swing
hai all,
now i do one project in java.that project's GUI is Swing. But i don't known swing (basic).So how to write a code for open new txt file and "Open window " in menu item on swing.that means when i click the "New" on menu that time open a new txt file. open also like that type.
plz give me that code ! very urgent
Advance Thanks !
RSKSwing Tutorial:
http://java.sun.com/docs/books/tutorial/uiswing/index.html
Since you don't know the basic of swing read the tutorial, it is for your own good because it is useless if we provide you with a code you don't even understand and how it works.
If you want a menu read the tutorial about using menus and for opening a file read using JFileChooser.
note: don't use the word urgent because it implies that your problem is more important than others. -
Java API to read the Encrypted Values from Windows Registry settings
Is there any Java API to read the Encrypted Values from Windows Registry settings ?
My Java Application invokes a 3rd party Tool that writes the key/value to windows registry settings under : “HKLM\Software\<3rdparty>\dataValue”.
This entry is in BINARY and encrypted with 3DES, using crypto API from Microsoft.
3rd party software to encrypt the data stored in registry it
either uses C++ code: and uses the call “CryptProtectData” and “CryptUnProtectData” or
If it is a .NET (C#) it uses the call “Protect” or “UnProtect” from class “ProtectData” of WinCrypt.h from the library “Crypt32.lib.
Note: The data is encrypted using auto-generated machinekey and there is no public key shared to decrypt the Encrypted data.
Since the data is encrypted using auto-generated machinekey the same can be decrypted from a .Net / C++ application using CryptUnprotectData or UnProtect() API of WinCrypt.h from the library “Crypt32.lib.
To know more about Auto-Generated MachineKey in Windows refer the links below
http://aspnetresources.com/tools/machineKey
http://msdn.microsoft.com/en-us/library/ms998288.aspx
I need to find a way in Java to find the equivalent API to decrypt (CryptUnprotectData) and Microsoft will automatically use the correct key.
But i couldn't find any informato related to Java APIs to enrypt or decrypt data using auto-generated machinekey.
Is there a way to read the encrypted data from Windows regsitry settings that is encrypted using the Auto-Generated Machine Key ?
Kindly let me know if Java provides any such API or mechanism for this.If the symmetric key is "auto-generated" and is not being stored anywhere on the machine, it implies that the key is being regenerated based on known values on the machine. This is the same principle in generating 3DES keys using PBE (password-based-encryption). I would review the documentation on the C# side, figure out the algorithm or "seed" values being used by the algorithm, and then attempt to use the JCE to derive the 3DES key using PBE; you will need to provide the known values as parameters to the PBE key-generation function in JCE. Once derived, it can be used to decrypt the ciphertext from the Regiistry in exactly the same way as the CAPI/CNG framework.
An alternate way for Java to use this key, is to write a JNI library that will call the native Windows code to do the decryption; then the Java program does not need to know details about the key.
That said, there is a risk that if your code can derive the key based on known seeds, then so can an attacker. I don't know what your applicatiion is doing, but if this is anything related to compliance for some data-security regulation like PCI-DSS, then you will fail the audit (for being unable to prove you have adequate controls on the symmetric key) if a knowledgable QSA probes this design.

How to process other task when reading the data from a file?
Hello,
I met a problem. I created a GUI to control the audio data processing. When the "Start" button is pressed, a block of data is read from the audio file and processed, then loop.But other buttons or method cannot be operated in that procession until all data is processed.
How to let the other methods work under that circumstance? Should I use multiple threads?
The relative code:
SourceDataLine line;
boolean stop = false;
// When press "Start" button, the following method is invoked:
public void play(){
line.start();
int bytesRead = 0;
byte[] dataBuf = new byte[7500];
while (bytesRead != -1& !stop)
try
bytesRead = audioInputStream.read(dataBuf, 0, dataBuf.length);
catch (IOException e)
e.printStackTrace();
if (bytesRead >= 0)
int bytesWritten = line.write(dataBuf, 0, bytesRead);
line.drain();
// When press "stop" button, this method is invoked.
public void stop(){
stop = true;
line.stop();
// When press "***" button, the following button is invoked:
public void ***(){
Many thanks.Looking forward to getting your answer.You have to use a seperate thread :
Wheb you press the start button, you have to make sure a seperate thread is started :
Thread runner = new Thread(){
public void run(){
//Here comes your code which reads the file
runner.start();

How to embid java code in JavaScript
Hi!!
I am writing JSP program.
Do u know how to embid java code in javascirpt
ex:
<SCRIPT>
alert("hello");
<%
System.out.println("Hello...Satish. ");
%>
</SCRIPT>
This alert message is not comming when i add the java code.Do u know how to embid java code in javascirptYou can't.
Java/JSP code runs, and produces a web page. At this point any html/javascript is treated just as "text" to output.
That web page is then sent to the browser which runs javascript.
All java code has been run/removed - maybe generating HTML in its place.
The only way to call java code again is to submit an HTTP request - normally by clicking a link/submitting a form. -

Could any one provide sample code.

We can't Bring Java Inside the ABAP. Both are running in different Environments.
and also ABAP Codes are runs on BASIS.
-Basis is a middleware between ABAP codes and Ur OS.
-Contains set of programs to load,RUN,intepret the ABAP program..
So Both are Different.

How to write a pgm to change the existing encrypted password
Hi all,
can anybody tell me how to write a pgm to change the existing encrypted password.
thanks in advance.Well, it's going to depend on how it's implemented in the current system.
But basically it's going to look a lot like the current login actions. Presumably you have something that takes the user ID and password, encrypts the password, looks up the encrypted password in the database matching that user ID, and compares them. This functionality would also take a new password (preferably twice so they can be checked for consistency), and if the existing encrypted passwords match, it will encrypt the new password and put it in the database where the old one was.
And if the application has a mechanism for new users to sign up, it'll look a lot like this as well.
But I'm just guessing. This is all going to depend on how the existing functionality is written. Probably the best thing you can do is talk to a programmer at your organization who has worked on the application, and ask them for help.
Hope this helps anyway. -

How to write Java Scripts in Apex
Hi All,
Can any on tell me how to write Java Scripts in Apex.
Thanks in Advance,
MukundIf you want to link your custom JavaScripts to an Apex page, you have several options:
1. Add an HTML Region on Page 0 (Script will be written to every page) called something like "JavaScript & CSS". In this region add your Script to the region source like this:
<script language="JavaScript">
function hell ()
alert ("Hello World");
</script>
2. Add a similar region to the page you are working on (can only be accessed on this page)
3. Create an external JavaScript file and either load it into the WORKSPACE or into the images (/i/) directory on the server. You can then link the JS into you page via modifying the Page Template.
Hope that makes sense. Let me know if you want any further help with option 3.
