How to wait until setPage(number) is finished

SR 3-8311228061
When calling getStrings, found I need to iterate the pages of the doc/xls/etc
However Autovue Support tells me that setPage() is asynchronous
I asked how to wait until setPage() is complete, they suggested I post the question here
Note, at the time its called the viewer (desktop version 20.2.2) is on the task tray, but not rendering the document
Its only loaded to extract the text
here is the blip of code
for( curPage = 1; curPage <= pages; curPage++)
vueBean.setPage( curPage ); //its necessary to call setPage even for page 1
//If setpage fails stop (per Daniel/Oracle)
int thisPage = vueBean.getPage();
if( curPage != thisPage )
//This message never shows up
String msg = String.format("Pages[%d] thisPage[%d] curPage[%d] ", pages, thisPage, curPage);
AdeptApplication.INSTANCE.publishEvent("file-event", msg,
new SystemEvent(this.fileName, "GETTEXT_PAGEFAILED"));
break;

The code you have is to know whether changing pages succeeded or not, and unless you are trying to set a page number that is out of the page count it will always succeed
So, yes, your test is the same as if (false)
Now, page loading is done in an asynchronous manner
1. you ensure that the page (the container for all the page artifacts) is created, synchronously
2. the page content are streamed on another thread
3. once the page is loaded, an event is sent VueEvent(VueEvent.FILEEVENT, VueEvent.ONPAGELOADED)
So you should be able to query for info after you received the page loaded event
Now, word documents are an special kind of documents, so you need to be aware of some specific issues.
The same way ms-word does not know the total number of pages until the ENTIRE document is loaded, AutoVue will not be able to notify you either.
And as Word, AutoVue allows you to display the pages that are already loaded, and you may query for some of its contents too. BUT you can not query for page info when the page is been loaded (or obviously not yet loaded)
The loading is a 2 phase one, part is done on the server (native code) and part is on the java side (display)
So you will not be able to iterate
for( curPage = 1; curPage <= pages; curPage++)
simply because page count is not known. You need to query doc info more than once.
If page count = -1, you need to iterate for each page and then, test whether setPage() != getPage() and/or page count has been updated.

In our program, we are concerned about reducing CPU work; how to wait until a boolean condition changes in a "while loop"?

Is there a way to wait until a boolean condition changes (instruction is sent) in a "while loop" (because I want the program run until I press exit button)? Now it is consuming a lot of CPU because it is running the loop very fast waiting for instructions unless I stop the program.
Thank you.

Use /functions/time and dialog/wait until next millisecond multiple in the
loop. Input 100ms.

GP: How to wait a specific number of days?

Hello everybody,
I am searching for an idea how to create a step in my Guided Procedures process which waits until a specific day (or a number of days from it's start).
I have thought about implementing a Java Callable Object which waits until completing the step - but I fear to create a lot of server load with that.
Does anyone have a different idea?
Maybe there is a way to use due days and a loop?
Thanks for any suggestion
Ingo

Hi,
I think you can do it :
STEP A - Complete
STEP B - Waiting
STEP C - After complete B
You can developer a Job that uses Guided Procedure API (http://help.sap.com/saphelp_nwce10/helpdata/en/44/0d3e1626821c9de10000000a11466f/content.htm) to complete STEP B, based on creation date. This Job can execute on each hour, 15 minutes, day. Or on way that you need.
So, after execute JOB and a step was select, complete it, so STEP C was activated.

How to wait until the 1st part of the processing is done

Hi,
I had a hard time to combine two parts of processing in one .vi file, and thus would like to get some advice/help through the forum.
Attached is the partial finished vi file I made. You can see that it is composed of two parts. The upper part is to run a bat file (check_result.bat), which generates a result.txt file. The lower part is to use the result.txt file as an input file, and check if the key word called "test case passed" is included in the result.txt file or not. So I want to run the upper part firstly, and then run the lower part after the upper part is finished.
However, I don't know how to connect the two parts in a right way that the lower part only starts running after the upper part is finished. Any comments/help is highly appreciated.
Thank you in advance.

The magic of dataflow!
All you need is a data dependency between the two parts. Often critical parts of each section contain error terminals, so you can just string em along in the proper order and each part must wait until the previous node has finished.
In your particular case, the read operation has no error input, so you can recruit any other input. Create a fake data dependency by strategically placing a small sequence frame containing common code. The sequence cannot start until all code that provides imputs has finished, serving your purpose.
Of course it seems silly to even try to read the file if the previous node failed. Right? So simply place the second part inside a case and hook it up to the error output. Now the second part (1) waits until the first part has finished AND (2) execute only of the first part succeeded. No sequence needed.
All clear?

Code to wait until one event is finished before starting another?

Hi all,
Coding isn't my strong point but I have a basic understanding of how functions etc work.
I've been learning about referencing symbol timelines with the awesome tutorial from the Adobe Blog, included below.
http://blogs.adobe.com/edge/2012/07/18/tutorial-leveraging-independent-symbol-timelines/
I've been able to get my symbol to play from a certain part of it's timeline depending on whether the mouse is rolling in or out but now I'm a little bit stuck.
The mouseover event triggers an animation and the mouseout triggers another animation that starts from the same frame that the mouseover animation ends with.
The problem is this. If I move the mouse quickly over the buttons, the first animation will play halfway through and when the mouseout triggers the second animation, the first animation will seemingly "skip" to the ending and move straight to the first frame of the second animation.
I know enough to code it so that the second animation will check if the first animation is still playing before starting by using an else/if statement. Using this method I only know how to skip the second animation if the first is playing but that isn't really what I'm looking to do.
Here comes the question; can anyone explain to me how to create a wait loop in Edge Animate?
When I say wait loop, I am talking about code that will check a variable and perform an action if the variable is true OR loop back to the start of the function if the variable is false (to check the variable again).
The behavior I am trying to achieve is somewhat like queuing the second animation so that it will "wait" until the first animation is played before beginning the second animation.
Any ideas?

Ok Mr Doon,
Clearly, I read to quickly
The behavior I am trying to achieve is somewhat like queuing the second animation so that it will "wait" until the first animation is played before beginning the second animation.
So, say the anima symbol is a 2s animation and has autoPlay set to false. There are two instances anima-1 and anima-2 on stage.
The event handler anima-1.mouseover starts the first animation :
We select Stage in the code panel and place before the first Symbol.bind… the declaration for two symbol (stage) variables :
Inside the anima timeline, click the top left bullet+curly brackets icon and select complete : when the animation is complete, we set the boolean variable (what is not very clean here is that this is done for the two instances anima-1 and anima-2) :
The event handler anima-2.mouseover starts the wait loop, by calling a function defined at the stage level :
More precisely, the function is defined in the document.compositionready handler. It defines (and stores in variable waitLoop in order to be able to remove when finished) an interval, that is the repeated call, every 10 ms, of an inner anonymous function.
The latter simply tests the boolean and when its true
- starts the second animation ;
- clears the interval.
You can download the example here : https://www.box.com/s/6yxjfmrqd0b5zbhmd3lx
You can hover over the left rounded rectangle, and immediately after over the second one. Subsequent rollovers are not handled, but it gives you a possible logic to adapt to your particuliar problem (that I still do not understand completely : it's hard without seeing).

How to wait until an Entourage Schedule item completed

I am trying to script the "Send & Receive All" operation in Entourage, and I have found that I can trigger the process off (from within my script) by:
tell application "Microsoft Entourage"
execute schedule "Send & Receive All"
end tell
However, the script continues to process while the scheduled actions take place.
Is there any way to wait until the schedule actions complete and then process the rest of the script?
Thanks
Susan

Glad to help, Susan
I found out about "connection in progress" by looking at the properties of "application" in the Entourage dictionary:
connection in progress boolean [r/o] -- Are there any network connections in progress?
(In fact I searched through the dictionary for the phrase "connect".) The property is a boolean (true/false), and my script uses a "repeat while" loop to test for that boolean condition.
As well as properties, the Entourage application object also has elements. These include "POP account", "IMAP account", "Exchange account" and "Hotmail account". These can be referred to "by numeric index, test". So if you pass a list of accounts to the "connect" command, Entourage will connect and download mail from those accounts. For example, if you have two POP accounts, this works:
tell application "Microsoft Entourage" to connect to {POP account 1, POP account 2}
AppleScript lists are contained in curly braces.
But it's simpler (and less prone to error) to do this:
tell application "Microsoft Entourage" to connect to every POP account
Alternatively, the "test" lets you refer to individual accounts by name - a list isn't essential, despite what the dictionary says:
tell application "Microsoft Entourage" to connect to POP account "My Account"
There's many ways of skinning a cat.
To answer your more general question, though, there is no one "user guide" for AppleScript. You can learn the about the basics of the language from the AppleScript Language Guide. But that will tell you nothing about how to script particular applications. This is because every developer, if they do implement AppleScript in their application (and lots don't), implements it in different ways.
So as well as learning AS, for each application that you want to script you have to learn a slightly different set of commands. There's an awful lot of trial and error involved, but one way to learn is to look at scripts that others have written. There are good resources at Apple's own AppleScript page and at AppleScript Central among others. For specifically scripting Entourage, try Paul Berkowitz's scripts.
Different people will also recommend different books. My recommendation is AppleScript: The Definitive Guide by Matt Neuberg, but again it's not application-specific.
Hope this helps, at least to give you some pointers.

How to wait until html page is completely rendered

I use a JEditorPane to display HTML and i want to print it to an image. so i tried to load the page (JEditorPane.setPage(URL url)) and wait until the property "page" is fired. Then i printed the component to an image.
My problem is that the page wasn't completely loaded (rendered?) when i tried to print it.
Is there a way to be notified when the page is completely rendered?
thx in advance
~elchaschab

However, you might consider setting the document property for it to be
loaded synchronously.i've already used my own HTMLEditorKit for synchronous document loading.
class MyHTMLEditorKit
extends HTMLEditorKit
public Document createDefaultDocument()
Document doc = super.createDefaultDocument();
((HTMLDocument)doc).setAsynchronousLoadPriority( -1);
return doc;
You probably already played around with calling repaint() and
validate() before printing.i tried to call repaint and validate before printing but
still it doen't work. :(
As a last resort, you could experiment with calling the printing
routine written as a thread passed to invokeLater(), although there is
no obvious reason why this would make a difference. i don't understand what i should do with invokeLater().
could you please give me a short example?
thx,

URLLoader - how to wait until URL is loaded and then contine...

Hello,
I have litle problem because I don't know how to load
external XML file, wait when loading is completed and after that
continue with next code.
Consider following situation. I have a function in
actionscript, let's say, handleXML()
function handleXML() {
someURLRequest = new URLRequest("some XML file");
someURLLoader.addEventListener("complete","LoadCompleted");
someURLLoader.load(someURLRequest );
Alert.show("Print Second")
function LoadCompleted(event:Event) {
someXML = XML(someURLLoader.data)
Alert.Show("Print first")
The problem is, when someURLLoader.load is called, Alert
window with Print second is displayed and then "Print first" alert
is displayed because flex perform action behind someURLLoader.load
and then perform function LoadCompleted().
I would like that first, when someURLLoader.load is called, flex
wait until external XML is loaded, display "Prinf first" alert AND
THEN continue with code and displat "Print second" alert.
It is possible to do it someway??
thanks for help

Hi, thanks for answer, but I think it is the same:) So what
happens if I change your code like this...
srv = new HTTPService();
srv.url = "some XML file";
srv.resultFormat = "xml";
srv.addEventListener( ResultEvent.RESULT, loadCompleted );
srv.send();
Alert.show("Print Second")
function loadCompleted( event:ResultEvent ) : void
someXML = XML(event.result);
Alert.show("Print First")
In this case, after calling srv.send(), next code in the
fuction is performed, so the Alert "Print Second"" is dsplayed.
After that, URL request is completed and "Print Second" appears. I
think it is because data calls are asynchronous. Is it there a
possibillity to wait after calling send() function, until the
request is processed and then continue with code which the send()
function was called from ? It means, first Alert.show("Print
First") is executed and then Alert.show("Print Second").???

How to wait until all components painted?

Hi - I have searched for hours for an answer to this and have yet to find something so any help is much appreciated!
Ive posted some code below to simulate the problem im facing. This is a simple frame which has a couple of custom jPanels embedded within it.
When this is run, the first 3 lines i see are:         I want this comment to be the last thing output
        Now finished panel paint
        Now finished panel paintBut, as this output suggests, i want the "I want this comment to be the last thing output" line to be displayed after the two panels are completely painted on the screen (in real life i need to know my components are displayed before the program can move on to further processing). Of course, if you cause a repaint you see the "now finished panel paint" each time, but im not interested in this, im simply interested in how to overcome this when the frame is first created and shown.
Ive tried everything i can think of at the "// ***** What do i need to put here? ******" position but nothing seems to work... In short my question is how can i construct my frame and get it to ensure that all components are fully displayed before moving on?
Sorry if the answer to this is obvious to someone who knows these things, but its driving me mad.
Cheers
import javax.swing.*;
import java.awt.*;
public class Frame1 extends JFrame {
public static void main(String[] args) {
    Frame1 frame1 = new Frame1();

    // to ensure that the System.err.. call below
    // is only executed once both panels paint methods
    // have finished?????
    System.err.println("I want this comment to be the last thing output");
    System.err.flush();
public Frame1() {
    this.getContentPane().setLayout(new FlowLayout());
    MyPanel p1 = new MyPanel(); p1.setBackground(Color.red);
    MyPanel p2 = new MyPanel(); p2.setBackground(Color.green);
    this.getContentPane().add(p1, null);
    this.getContentPane().add(p2, null);
    this.pack();
    this.setVisible(true);
class MyPanel extends JPanel {
    Dimension preferredSize = new Dimension(200,200);
    public Dimension getPreferredSize() { return preferredSize; }
    public MyPanel () { }
    public synchronized void paintComponent(Graphics g) {
      super.paintComponent(g); //paint background
      // do some irrelevant drawing to simulate a bit of work...
      for (int i=0; i<200; i+=20) {
        g.drawString("help please!",50,i);
      System.err.println("Now finished panel paint"); System.err.flush();
    } // end of MyPanel
}

Thanks both for your replies.
When doing the "Runnable runnable = new Runnable(){public void run(){ frame1.paint(frame1.getGraphics());....." method i sometimes see
    Now finished panel paint
    Now finished panel paint
    I want this comment to be the last thing output
    Now finished panel paint
    Now finished panel paintwhich is a pain.
As for making a new Runnable to do the system.err.println and then doing the SwingUtilities(invoke) on that runnable, that didnt work for me at all.
So... in the end, my solution was to have the paint method set a boolean when finished and the main program sleep while this is false
     // Dont want to sleep for say a few seconds as cant be sure
     //painting will be finished, must monitor state of painting ...
     //therefore use while loop
     while (!isOk) { // isOk is true when both panel paint methods complete
         System.err.println("Waiting......");
         try{   Thread.sleep(300 /* wait some time */); }
         catch(Exception e){}
       System.err.println("Thankfully this works");which is a kind of mixture of both your suggestions i guess!
Thanks for your help, much appreciated.

How to generate Serial(Unique) Number for finished goods?

Guru's,
How do i generate Serial(Unique) Numbers for finished goods.Suppose,if we get an order for a finished good A of 10 qty.We want to generate unique number to identify each and every A item separately for quality purpose.Any help is much appreciated.
thanks Guru's

Depending on serial control of item, you will need to generate serial numbers at the time of WIP Completion transaction using Serial Entry window (i.e. if serial control is At Receipt) or at the time of job creation (i.e. if you are using serial control as predefined)
In latter case, you will have to use MES or MSCA screens to perform serialized WIP completion.

Waiting until a gui frame finishes.

Hi, I'm trying to implement something like JOptionPane or JFileChooser, where if you invoke methods of those classes to show GUI windows your program stops executing until the user click OK or something like that. I've been trying to implement this sort of functionality, but I'm getting nowhere at all with this. I'd like to implement something like this so that I wouldn't have to create call back methods in my program to be used by the GUI window when it's done, since that's a dirty way of doing it. Any help would be appreciated. Thanks.

How can I wait until a Swing.Timer has finished?

I have a Swing.Timer runing which displays some animated text (more precisely it fades out a text with a delay of 50 until all characters are erased.
Afterwards a time consuming operation shall begin. How can I achieve that this operation waits to start until the text has been faded out? The time to fade out the text depends on the length of the text, of course.
So, how can I make the operation waiting until the Timer has finished its work?
Thanks,
Dirk

How can i get program to wait until file is loaded?

Hi all,
I keep getting a null pointer exception error thrown when it shouldn't. I'm 99% certain that its being generated because the program speed is faster than the load file time. Is there any way to make the program wait until the file is finished loading? I know you can set up a for loop that will take up some time but I wanted it to be more accurate so that no errors will occur on any machine. Here is the code
RunMainProg();
          String[] TempHolder = new String[HowMany*2];
          try
              BufferedReader readerOne = new BufferedReader(new FileReader("TempMDLFile.txt")); // file just save from RunMainProg()
              String lineOne;
              int i=0;
                   while ((lineOne = readerOne.readLine()) != null)
                        if(i>=TempHolder.length)
                        break;
                         TempHolder=lineOne;
                         i++;
          readerOne.close();
               catch (IOException f)
                    MakeDialog ErrorDialog = new MakeDialog(TopWindow, "Load Error", "Error - The file you entered does not exist", "Error", "OK", "OK", 0, 0);
               for(int i=0; i<TempHolder.length; i++)
                    if(TempHolder[i] == null)
                    i=0;
               FormatData TestSequences = new FormatData(TempHolder); // problem occurs at this line
I have looked all over and can't seem to find a way to verify if the file is loaded, or to get it to wait until it has. Any help would be much appreciated. Especially if you can supply some code snippets :)
Much obliged
Drb2k2

okay, I added some test code that I was using to try and iron out the problem. Perhaps its best if I run through what happens.
1. I get the data from the text box, and an external program is run which generates some text files. These files are then loaded and examined and some new data is appended to the old. This is the process
FormatData TestSequences = new FormatData(TempHolder); Now every time its run first time around its fine.
2. When I try and do exactly the same thing with the new appended set of data the null exception is thrown. Now Dr Clap, I thought exactly the same as you did, but... If i add the following bit of code before the FormatData call..
for(int i=0; i<TempHolder.length; i++)
System.out.println(TempHolder);
It will produce the data without the appended info, and some null sequences.
The size of TempHolder is adjusted depending on the amount of data submitted, so somewhere along the line its just not working.
3. Now for the fun part, eventually if you put the call in a loop it will correct itself and produce the outcome, but needless to say i'd rather not have my program catching a load of nullpointerException errors.
Finally as for the code
for(int i=0; i<TempHolder.length; i++)               {                    if(TempHolder[i] == null)                    i=0;               }That was an attempt to stall the program until no null sequences were found. Sort of getting around the problem in 3.
Dr Clap is a legend on these posts and his advice is well recieved but I have no idea how to view a stack trace or what benefit it has. Any tips on this would be great.
Thanks for your help so far

Program needs to wait until BDC will get over

Hi Experts,
In my report program i am using BDC call transaction. Once this BDC action will get over after that i need todo some logic in my program. How to wait until BDC will get over?
Anyone have idea?
    CALL TRANSACTION 'CK41' USING zdata
                            OPTIONS FROM g_s_options
                            MESSAGES INTO msg_tab.
    PERFORM call_processing USING wa_default-kalaid
                                     wa_default-klvar
                                     wa_default-kokrs
                                     wa_default-bukrs.

Hi,
Program gets over in BDC call transaction after call transaction statement.
If you use call transaction statement as below,
CALL TRANSACTION 'ME22' USING bdc_tab MODE 'N' UPDATE 'S'     MESSAGES INTO messtab.
Here Update 'S' means update will be syncronouse so program will wait untill this BDC gets completed, if you will not select this statement then by default program may take update 'A' which is asyncronouse means BDC will be processed parallel to this program, please check.
After this call transaction statement you can do code changes as per your requirment in the same program.

How can I prevent the flushing of the buffer until the playing is finished in AS3?

How can I prevent the flushing of the buffer until the playing is finished in AS3?
Is it possible?
The buffer is emptied and flushed 10-11 seconds before the real end of the flv file.
The file is locally saved and I stream it though crtmp server.
I cannot seek the last 10 seconds because of empty buffer. How can I stop flash from flushing the buffer at end?

i used the same code and i got it working correctly...
thanx a lot fot it...
now i have one more problem with it.
Actually i created a new class 'ErrorDialog' and the function showErrorDialog() inside it.
now i want the option YES_NO_OPTION and the function sayshowMsgDialog() returning int value indicating the option selected from the dialog box.
