Create a delay when a change occurs

Hallo ,
I would like to know how a delay can be created when i change the value of a pre defined control . The range control is a prefedined option that allows me to change the sensitivity . since it takes few seconds for the new sensitivity to be set i would like to create a delay when this value is changed . Kindly help me on this .
thanks and best regards,

Text flows create a delay when an overflow creates a new page, preventing you from reading the page number, giving error

Hi all!
I am creating a script to generate automatically a photo catalog; the idea is to prepare a master document with a text frame in the master spread with auto flowing, then insert images with their caption by the script, letting the system create automatically the subsequent pages when necessary by an unique flow of text.
My catalog is divided in sections, each represented by a different master spread; so I have to know in which page I am working when the script put there an image, just to link the current page to the proper master spread.
To simplify everything I have resumed the core of my script here, using text instead of images:
/* load a master document, only containing an empty text frame in the master spread, connected to the main text flow */
var doc = app.open(new File("~/Desktop/mySampleDoc.indd"));
/* I work on the story, thinking that whenever the textframe of the first page will be full, another text frame will be created in the next page (automatically created) */
var story = doc.pages[0].textFrames[0].parentStory;
/* now I put some lines of text into the story, expecting the creation of a new page when the first one will be full */
for (var i = 0; i < 100; i++) {
   /* this is next line: */
    story.insertionPoints[-1].contents = "this is line n. " + i + "\r";
    /* here I want to know on which page is the line just created (error is generated here just during the creation of the new page + text frame) */
    thisPage = story.insertionPoints[-1].parentTextFrames[0].parentPage.documentOffset;
   /* and now I print page number */
    story.insertionPoints.item(-1).contents = "current page: " + thisPage + "\r";
The big problem is: when the first text frame is full and an overflow is generated, a new page with a new text frame belonging to the main text flow (as the master spread wants) is generated; but it seems my script requests the page number before the new page with the new text frame is born, and an error is given.
It seems like the script goes too fast in respect to the creation of the new page.
If I delete the line thisPage = story.insertionPoints[-1].parentTextFrames[0].parentPage.documentOffset; everything is ok.
I tried to introduce a delay until 3 seconds without any effect.
I tried also to show or zoom the new page before the page number request, thinking to force the system to wait until page is really born, also without any effect (by the way, I was not able to show the page during the script's additions of text!).
Someone can help me?
Many thanks to everyone
Roberto

Many thanks: you are right!
Unfortunately, I am at the very beginning with ExtendScript, and there are so many things I don't know until now...
With recompose() everything works very well, and it give me a solution also for redrawing the page while the script is working...
Many thanks, again!

Bug? - PSP LED Moves on FP when Binding Change Occurs

[LabVIEW 2010]
When I update the binding on the control the PSP LED moves. This is annoying

This was reported to R&D (CAR ID # 296216) for further investigation. I did try saving the VI before the variable to which the control was bound was changed, but the same behavior occurred.
Thanks for the feedback!

Active Sync running when a change occurs on the target resource

Does anyone have any insight on if I can configure an Active Sync to run when a target resource attribute changes? In the docs I only see manual running and scheduled running.
Thanks
Edited by: robspierre19 on Jan 25, 2008 12:35 PM

Hello.
Keep in mind that Sun IdM connects to resources via agent-less, over-the-wires connection. As such, there's no agent or software running on the managed system to "alert" IdM that a native change was made (e.g. a target resource attribute change).
ActiveSync is in most cases a form of polling -- it periodically checks for native changes. How it checks depends on the resource. In some cases, it checks change logs (LDAP), in some cases it checks a last-modified flag (e.g. DB table), in some cases it looks for an HRMD_A message (SAP HR), etc.
The Manual and Scheduled (Automatic) is how you want the ActiveSync process to start -- e.g. automatically start when IdM starts (Application Server is booted) or start only when you manually select it to start. The polling frequency is configurable for every ActiveSync adapter in the ActiveSync Wizard (Resources tab).
Does that make more sense?

Trigger java client update when table changes

I have a Java Swing client and a C worker program. Both need to communicate with each other via events (C writes progress to Oracle table, Java Swing client displays progress to user).
I thought I'd do this via a trigger on an oracle table. However, I couldn't figure out how to achieve that. Well, creating the trigger was the easy part, but how do I let the trigger and as a follow-up a stored procedure communicate with my Java client? All the info I found was about triggers and how to store a Java method in an Oracle DB. That's not what I need. I guess I need to register my Java client somehow to monitor the trigger / table.
Does anyone know how to do that? I'd prefer to not use any additional libraries (Oracle AQ libraries, Oracle streams). A simple trigger would suffice.
Thank you very much for your help!

I don't agree with either of these comments. Please explain them and provide any supporting documentation or other reliabe sources that you are basing these comments on.
In particular clarify whether your comments are about the technology of notification in general or whether you feel that the notification solution is not appropriate for this particular use case.
Polling is generally a terribly wasteful, inefficient and non-productive method of trying to identify changes that happen in a database. Provide supporting documentation for that.
Naturally the actual metrics for this depend on the number, types and frequency of the DB changes in general and with their relation to the polling frequency in particular.Yep. And most of the time the specifics for that is such that one or both the following is true
1. The requirements are wrong (for example no GUI needs to be update 100 times a second.)
2. The requirements are loose enough that polling is perfectly adquate and appropriate solution.
Oracle itself has gone in the opposite direction with the technology that it develops as can be inferred by the various methods provided in recent releases to support replication and the technology underlying the support of fast refresh materialized views.
Oracle has all sorts of stuff in it. That doesn't mean that it ideal for all situations or even most situations.
These technologies include Advanced Queuing, Change Data Capture, Advanced Replication, Standby Databases and the like.
The only major Oracle technology that I am aware of that does not tend towards publish/subscribe is LogMiner and it does not use polling but rather uses a batch query process.
And yet for 20 years people have managed to implement large solutions without that.
Detection of DB changes is difficult for even small single tables without using functionality provided by Oracle specifically for that purpose. There are many, many references in these forums and on the web in general where developers have attempted to 'roll-their-own' procedures for detecting changes after the fact. Most of these attempts are flawed both in their design and execution.
And yet you think that this new technology will provide immediate error free solutions both on Oracles sides and the implementors side?
Polling is generally wasteful and inefficient for several reasons. First, poll queries can execute repeatedly when there haven't been any changes at all. This effort is entirely wasted and non-productive.
I have a large volume database server whose cpu utilization is less than 3% with a projected volume this year of 3/4 billion dollars. In the mid 1980s I was more concerned with utilization. Not so much any more.
On the other hand experience would suggest that developers have far, far more problems getting the database designs right in the first place. So I don't have great confidence in their ability to use brand new technologies to solve large volume problems.
And if they don't have large volumes then the point is moot.
The poll queries cannot easily determine exactly when the change occured; change meaning it was COMMITTED to the database. The common approach of updating columns such as MODIFIED_DATE within a trigger are flawed because any such date/time assigned in the trigger is virtually guaranteed to occur BEFORE the data is actually committed.
The classic flaw manifests itself when the trigger assigns a value before midnight but the commit actually occurs after midnight. Thus two INSERT/UPDATES can have their data COMMITTED at exactly the same SCN and timestamp value but the MODIFIED_DATE values can be for two different days.
There is no way to query this data on a nightly basis to get 'changes that happened today' with the risk of missing data the next night when the extract occurs, or worse, duplicating some data in the extracts for two different nights.
I agree that the design you specified is flawed.
It however is an excellent demonstration of how a developer might create a flawed design - as I a suggested. New technologies do not fix flawed designs. All they do is provide even more ways to create flawed designs. Which is exacerbated by large volume needs.
And 'pushing from the database'? The change notification process is similar to publish/subscribe mechanisms and also similar to the way that listeners are used in Java.
Certainly you wouldn't suggest that Java applications should 'poll' GUI objects to see if a user has taken any action would you?
I agree your analogy is not apt for this discussion.

Automatic email when a dump occured

Hi,
Is there a way to generate an email when a dump happens on an SAP instance.
Thanks

I have the same problem.
I want to create an email when a dump occured.
In RZ20,I assigned the method CCMS_OnAlert_Email as
autoreaction method to the MTE class R3AbapShortdumps.
I configured the method with SENDER,RECIPIENT etc.
'Execute method' on is set to 'the local server of the MTE to be prcessed'.
When a short-dump occured,the view 'Status Autoreaction' shows 'checked Run required',
but no Email is sent.When I start the method manually (edit->nodes->start method,the
email appears.
What did I forget or what's wrong ?

HT1040 trying to make an ibook and have 800 photos, want format of 8 photos/page, but default is not that- "create" the initial book from iphoto "album" it loads less than 800 pics and then when i change layout i have blanks.

trying to make an ibook and have 800 photos, want format of 8 photos/page, but default is not that- "create" the initial book from iphoto "album" it loads less than 800 pics and then when i change layout i have blanks.
if i clear the book so that it is all blanks and then try to load in the pictures i have it loses the chronology of the pictures that i had established in the album.
is there a way to import photos into an ibook template and keep the original order of the photos without having to do them one at a time?
also, is there a way to insert a photo rather than just dragging it? i have tried the cut and paste funciton but it doesn't seem to work, the target site doesn't seem to register with iphoto.
many thanks for your help.

Photos are added to book in chronological order. So if you want to add them to a book in the order you have placed them manually in an album do the following:
1 - select all the photos in the album.
2 - use the Photos ➙ Batch Change ➙ Date menu option as shown here. Select any date and add 1 minute between photos.
3 - select just one photo from the album and create a book from it.
4 - in the book click on the Options button ➙ Book Settings button and make sure the checkbox for Auto-layout pages is unchecked.
5 - drag the album with your book photos onto the book icon and they will be imported into the Photos tray of the book in your pre-determined order but not into the pages themselves.

What do you mean by "uploading in Acrobat"?
(Note that if you change the size of text, it won't reflow, so you end up with a mess. Answer is, probably not useful)

Did you ever fix this problem? The same thing happened when I just changed my kids passwords and now can't access their mail on their iPods or my iPad but I use the same email provider and mine is fine however I did not change my password. If you fixed it how did you?

When i change, create cycle (ksu1),I donot want to create transport request

when i change, create cycle (ksu1)
i donot want to create transport request ?
when i change/create cycle(KSU1,KSU2) i just want to change/create cycle.
i donot want to configure about cycle.
what should i do ?

Hi dittaporn
If you want to change whether your customization should create transport request or not you go in Tcode SCC4.Here you select your client for which you want to make changes and select NO CHANGES ALLOWED .After doing this setting, system will not create request pop up box.but i would suggest, you must ask your system administrator ( Basis people) before make any changes.
Hope this helps you and if found useful assign points.

Delay in reflecting changes to Org structure

Hi,
I have created one report to display the Staff Contact details using query. The query makes use of the logical database PNPCE. Whenever there is any change made to the org unit of any employee, that is the position of the employee is changed from one org unit to another, then it keeps reflecting in the previous org unit for quite some time and then is reflected in the new org unit.
However in PPOME_OLD, it can be seen in the new org unit.
Can anyone please let me know how this can be remedied, that is whenever the change is made, it should be reflected in the new org unit (through the report) immediately without any delay.
Thanks and Regards,
Pinki

Hi Kibo,
Thanks for the reply. When the query is run by any manager, the query fetches the contact details (it0002 and it0006 details) of the employees reporting to him. However when one person is shifted from his org unit to any other org unit,then that person continues to be in the prev manager's report (all ohter details like it0001) for about 3 to 4 days and then the change occurs.
In the selection field, i have the normal selection screen for the LDB PNPCE (no value is entered) and two more fiels :
Employee Status (3 - active) and Adress Record type (1).
The value of these fields do not change....
Can you please tell me how to check which field is not getting updated?
Thanks and Regards,
Pinki

Had difficulty with synching music. Music was deleted when I changed/added new info. Had to start over. So...I checked procedure and it say if you change anything, hit the apple button. Which one? Never had to do this previous to the new operatin

I was having trouble with synching my iphone 5 since the new operating system was installed. But I was waiting for my 6+ and figured it would be solved with my dandy new phone. No such luck. I downloaded a great deal of music and then added to it and synched again. Music gone, except paid for stuff bought on the phone. So I added more and tried to load it again, and it did. But now, I was afraid to add anything, backup, and synch for any reason as it takes 12 hours + to load my music.
So, I went back to basics and looked up the procedure. It does say that if you make a change, " you should hit the apple button before you synch." Which one?
No info on what they mean. And clearly this is a change. I'm feeling stupid, but lately, Apple makes changes and expects you to intuitively figure them out. I usually do but was stumped here. It might be nice to get a heads up when changes occur.
Please help !
Oh and also, I can't seem to download ringtones I have created.

I am syncing my iphone to my iTunes account and then I do a backup and also making sure all updates are current. Then by going to the my phone and then going to the right and selecting the restore my iphone.
Here is a picture of what I get
