How to check the value entered in one co from anethor CO

Dear All,
I have a Debrief screen in which one main region is attached to CO1 and a tab region is attached to CO2, the tab region is an independent region in the main rdebrief main RN,
Here i have a requirement if one of the field of the tab region is entered , that has to be captured in the Debrief main Region CO.
could you help in assisting this.
Regards
AK

AK,
You can get handle of any item in the page from the mainCO by getting handle of the bean. You will have to get the handle of the tabbed region and get the handle of the corresponding field.
Alternatively, you can get the value from the VO Attribute, if the field is mapped to a VO attribute.
Cheers

How to check the value in Table CDPOS

Mostly I can't see the following fields value in the table CDPOS,
(1) CDPOS-VALUE_NEW
(2) CDPOS-VALUE_OLD
In fact, it should have values, so how to check the values, is there any special method needed?
Thanks and best regards.

Ferry Lianto,
Thank you very much for your expertise.
It's helpful to get some contents via FM:CHANGEDOCUMENT_READ_POSITIONS, the problem is, to some kind of DELETION operation, the log in table CDPOS is very simple, I still don't know which contents were deleted even though I found records in table CDPOS.
Is there any other suggestions?
Thanks and best regards.

How to judge the mouse enter which one of buttons?

There two buttons(no text,only icon on them),
and how to judge the mouse enter which one of
them and show the different message at one textfield?

Try this. I don't know if the code works, but the true solution will be like it.
void mouseClicked(MouseEvent e)
    int mask = e.getModifiers();
    if((mask & InputEvent.BUTTON1_MASK) != 0)
        System.out.println("You touched to the button 1!");
    else if((mask & InputEvent.BUTTON2_MASK) != 0)
        System.out.println("You touched to the button 2!");
    else if((mask & InputEvent.BUTTON3_MASK) != 0)
        System.out.println("You touched to the button 3.");

How to refer the trigger written in one form from another form ?

How to refer the trigger written in one form from another form ?
Thanks,
Ravi Shankar

Try to convert the PL/SQL code from Forms trigger into a PL/SQL library(.PLL),
and then attach that PLL in your forms.
Note that all Forms objects should be referenced indirectly, for example,
you have to rewrite
:B1.DEPT_CODE := :B2.DEPT_CODE;
:B3.TOTAL_AMOUNT := 100;
==>
copy('B2.DEPT_NO','B1.DEPT_NO');
copy('100','B3.TOTAL_AMOUNT');
This is the best way to share PL/SQL code among Oracle Forms.

How to check the value from user input in database or not?

Hello;

My problem is my code do not work properly, sometimes, it tell me correct information, sometime it tell wrong information.
Could anyone help,please.Thanks
The following code is for check whether the value in database or not, and pop up a window to tell us.

You may have working code now, but the code you posted is horrible and I'm going to tell you a much much much better approach for the JDBC part. (You should probably isolate your database code from your user interface code as well, but I'm skipping over that structural problem...)
Do this instead:
    public void getData(String a){
        PreparedStatement p;
        String strQuery = "select count(*) the_count from customer where id = ?";
        try {
         //create a prepared statement object to execute sql statements, it's better, faster, safer
         p = c.prepareStatement(strQuery);
            // bind the parameter value to the "?"
            p.setInt(1, Integer.parseInt(a) );
            //execute the query
            ResultSet rs = p.executeQuery( );
            // if the query doesn't throw an exception, it will have exactly one row
            rs.next();
            System.out.println("i am testing");
            if (rs.getInt("the_count") > 0 ) {
            // it's there, do what you need to...
         else
              JOptionPane.showMessageDialog(null,"I could not find the value");
        catch (SQLException e) {
             // JOptionPane.showMessageDialog(null,"You may enter wrong id");
             // if you get an exception, something is really wrong, and it's NOT user error
        // always, always, ALWAYS close JDBC resources in a finally block
        finally
            p.close();
    }First, this is simpler and easier to read.
Second, this retrieves just the needed information, whether or not the id is in the database. Your way will get much much slower as more data goes into the database. My way, if there is an index on the id column, more data doesn;t slow it down very much.
I've also left some important points in comments.
No guarantees that there isn't a dumb typo in there; I didn't actually compile it, much less test it. It's at least close though...

How to get the value entered in input enabled field of a list output?

Hi all,
I am developing a program to display list with two input enabled fields . After users enetered the values into these fields I need to do some calculations based on these values and modify the value of another field in the list.
But i couldn't have an idea how to read the values after users enter into these fields.
Please help me on solving this problem? If possible please provide the sample code.
Thanks,
Aravind.

You can enable disable screen fields in at selection screen output event.
And by using loop at screen.
And for changing the values you can do in initialization event.
I Hope you are doing these in Reports.

How to check the value of "The Interrupt Status Flag"?

Hi, thank you for reading this post!
Invoking Thread.interrupt() sets the value of the Interrupt Status Flag.
Just wondering if there is a Java method to check the value of this flag? Or is using isInterrupted() or interrupted() the only way to check?

Below is the full code. As soon as the Thread.sleep() is taken out in main(), the interrupt is detected in the child thread. But if the sleep() stays, then the child thread goes into an infinite loop. It's not detected the interrupt.
//ParentInterruptChildThreadCatchedDemo.java
//Program function: This program demonstrates the parent thread (main()) interrupting a child thread (thread1).
//Threaded class
class TryThread extends Thread {
     //fields
     private String threadname;
     private long aWhile;
     //Constructor
     public TryThread(String tname, long delay) {
          threadname = tname;
          aWhile = delay;
     //run() method
     public void run() {
          while(!Thread.interrupted()) {
               //Do work
          try {
               System.out.println(Thread.currentThread().getName() + " was just interrupted!");
               throw new InterruptedException();
          } catch(InterruptedException e) {
               //System.exit(1);
               return;
public class ParentInterruptChildThreadCatchedDemo {
     public static void main(String[] args) {
          Thread thread1 = new TryThread("thread1", 2000L);
          thread1.start();
          try {
               System.out.println("main() goes to sleep for 10 second.");
               Thread.sleep(10000);
               System.out.println("Statement after main() sleep().");
          } catch(InterruptedException e) {
                e.printStackTrace();
             //Interrupt thread1
              int interruptFlag = 5;
              for(int i=0; i<11; i++) {
                   if(i == interruptFlag) {
                        System.out.println("Condition met, going to interrupt thread1 ...");

How to have the values fit in one page - smartforms

hi,
I am working on smartforms. I am facing a problem, that is for one purchase order there are many line items, the line lines should not split across pages.
For eg:
for the item 4, half of the description is in the first page then its continuation goes to the second page.
That is not the way i want. suppose if the wholes values does not fit in one page it has to move to the second page , but if the value is able to fit in the first page then it can be displayed in first page otherwise it has to move to second page.

Joseph,
This is exact place where PAGE PROTECTION can be used.
In the attributes of the tables, there will a tab OUTPUT OPTIONS. There will a check box for PAGE PROTECTION. Check that and it will take care of the row split across pages.

Ravi

Is there any way so that in 3rd chain( the one that takes more time to complete) i can check whether the other two chains have completed successfully or not.So that when this chain gets complete I can send the success notification for all the three chains.
If possible please tell me the step by step procedure for doing this.
I have no question on sending Email through process chain.

Hi
The OS Command is used for the following:
You use this process type to stop a system command in the operating system of an application server.
In the process maintenance for the operating system command, define:
The logical name of the operating system command you want to stop.
A command defined in transaction SM49 is used here. You can also change the command using the Change pushbutton.
The operating system of the application server on which you want to execute the command.
Additional parameters, as long as the defined command permits them.
The application server on which the command is to be executed. If you always want to use the current host, set the corresponding indicator. If you want to use a host other than the current one, enter this in the Target Host field; the system automatically deselects the Current Host.
After the run, you can find the standard text output by the command on the Process tab page of the log for this process.
For processes you may have implemented yourself, you can access this log using the CL_RSPC_SYSTEMCOMMAND=>IF_RSPC_GET_LOG~GET_LOG method.
I have never used the OS command myself, so I am not sure, whether it can be used in your case.

Hi Bibhuprasad,
I have a task to validate an employee Id. Suppose the employee Id is
E121212. Now as per the validation rule I need to check "the first letter
of the employee Id is a character and rest are numbers." How can I do this? Please reply.Everyone else has proposed REGEXP_LIKE, and while it's very powerful, it is
also very CPU intensive. You should always use Oracle's string functions
instead of Regular Expressions if possible.
I played around with
WITH data
     AS (SELECT 'E11212' s FROM DUAL
         UNION ALL
         SELECT '121212' FROM DUAL
         UNION ALL
         SELECT 'EE121212' FROM DUAL
         UNION ALL
         SELECT 'É121212' FROM DUAL
         UNION ALL
         SELECT 'E1EEEEEEEE' FROM DUAL
         UNION ALL
         SELECT 'E134343444' FROM DUAL)
SELECT s,
CASE
    WHEN (SUBSTR(s, 1, 1) BETWEEN 'A' AND 'Z') -- AND (TO_NUMBER(SUBSTR(s, 2, LENGTH(s)), 999999) > 111111)
      THEN 'Correct Format'
    ELSE
      'Incorrect Format'
    END mySSN,
    SUBSTR(s, 2, LENGTH(s)) AS theNumber
FROM data;I think that this can be worked so that it willl go what you require without using
REGEXP_LIKE.

Condition that checks the value of an Item derived from a select list

I want to conditionally display and hide items in a region based on a select list item.
Some items will display when the select list is at the default (%null%) and others will be displayed when the select list user selects from the select list.
The display is then updated when the "SAVE" button is pressed and the page processed.
How do I test the select list item to be null. The condition looks like this;
Type: PL/SQL Expression
:P1_SELECT is null
I also tried, :P1_SELECT is not null and :P1_SELECT = '%nul%'.
The latter changed the condition to :P1_SELECT = ''
How can I test the valu in P1_SELECT?
tia,
Sam
Message was edited by:
After a long day I saw that I did not write the condition correctly. Mea culpa.
slavanaway

I had the problem wrong.
The issue was a second field that could have a Y or N or null. When I checked it in PL/SQL expression as
:P_YN != 'Y' and :P_SELECT is null
assuming the null condition would resolve as != 'Y' I had to do an explicit check as
(:P_YN != 'Y' or :P_YN is null) and :P_SELECT is null
That fixed it.... I like null and I hate null

How to transfer the progress of just one game from one iPad to another iPad

Hi everyone! When I purchased an iPad Air, I gave my old iPad 3 to a family member who kept one of my games and its progress, but changed every other App to suit his requirements. My iPad Air has all MY Apps, which are different to the ones on the iPad 3. Both iPads use my Apple account.
I want to somehow transfer the progress of just the one game from the iPad 3 to the iPad Air and I don't want to back up my iPad Air to be the same as his iPad 3, which I know will transfer the progress of the game, but it will also mean I will get a load of Apps I don't want and more importantly, lose all my Apps and the progress in all my games.
i.e. can I transfer one game and its progress from one iPad to another without altering/deleting/removing existing Apps on either iPad.
Phew ... hope the above makes some sort of sense to someone!!!
Thank you

Transferring your prepaid cellular data account depends on your carrier. AT&T lets you move it yourself when you go to Cellular Data in Settings and log into your account with your previous AT&T user name and password. For iPads with Sprint service, you can set up an account on the new iPad and contact Sprint Customer Care (888-211-4727 and go through the menus) to deactivate the old plan and get credit for unused service. For Verizon, call the company’s customer service number for mobile broadband support (800-786-8419) and ask to have your account transferred.

How to read the value of OLAPDataGrid cell/s from external object

Hi,
I have an OLAPDataGrid control in an Adobe flex application,

any Idea how I can read the value of each cell at the

cell at the renderer?

I'm thinking that you'll need to look at the listData
property. I'm not
sure what you get in an OLAP Grid that orients you to your
cell position,
but I'd set a break point in the listData override of your
renderer and see
what you actually have, or look at the docs for the data type
of the
listData object that the default renderer expects to get.

How to check the values of view object?

Hi all,
I created a new view object by right clicking my application module. Now when I try to retrieve values
of the attributes of the view object I am getting null pointer exception. How do I check whether the view has
some values in it or not manually using select statement ? I try to find the view in my database at database navigator
but it was not there. Kindly help me out in this.
Thanks,
Phanindra.
Edited by: 887737 on Oct 19, 2011 12:53 AM

Hi,
Right click on application module(yourAM in model project) and press Run,Then you can confirm whether your ViewObject is working or not.
Note:
