How to manage the update at the end
Hi all
I can manage onFocus crushed by the paint method, but when the focus moves at the end of the field (the last focusable field), he again uses the
default behavior (drawing of a white rectangle). How can I customize this? Ex: keep the same as when it is in focus.
Thank you
Binh Nguyen
Piece of code here...
protected boolean navigationMovement(int dx, int dy, int status, int time){ invalidate(); return true;}
See you soon...

How to catch the end of an external task?
Hello
How to catch the end of an external task?
OS: Windows 2003

The code I wrote will run forever:
The work ends in fact, user_scheduler_job_run_details is updated (if you run the select statement in the loop in another session, it returns 1), but the selection running into the loop will always return 0.declare d date; n number; -- and more begin d := sysdate; dbms_scheduler.create_job( job_name => c_job, job_type => 'executable', number_of_arguments => 14, job_action => c_cmd, enabled => false, auto_drop => true ); dbms_scheduler.set_job_argument_value(c_job,1,'/c'); dbms_scheduler.set_job_argument_value(c_job,2,c_command); dbms_scheduler.set_job_argument_value(c_job,3,c_pw); dbms_scheduler.set_job_argument_value(c_job,4,c_pw_val); dbms_scheduler.set_job_argument_value(c_job,5,c_port); dbms_scheduler.set_job_argument_value(c_job,6,c_port_val); dbms_scheduler.set_job_argument_value(c_job,7,c_key); dbms_scheduler.set_job_argument_value(c_job,8,c_key_val); dbms_scheduler.set_job_argument_value(c_job,9,c_agent); dbms_scheduler.set_job_argument_value(c_job,10,c_batch); dbms_scheduler.set_job_argument_value(c_job,11,c_source); dbms_scheduler.set_job_argument_value(c_job,12,c_dest); dbms_scheduler.set_job_argument_value(c_job,13,c_log); dbms_scheduler.set_job_argument_value(c_job,14,c_yes); dbms_scheduler.enable(c_job); -- Job started, waiting... loop select count(1) into n from user_scheduler_job_run_details t where job_name = c_job and t.log_date >= d; exit when n > 0; dbms_lock.sleep(1); end loop; end;
Any help is appreciated.
Kind regards
LmocsiHello
It's strange, maybe you can try to use the timestamp type rather type date and with the help of an offset in the case where the work already finished for example d = systimestamp - second interval '1'
Another thing to watch is if you compare the dates in the same time zone, otherwise you must ensure that all sessions use the same time zone (setting the default_timezone attribute Planner can help).
Hope this helps,

I would like to know how to manage the ASN.1 encoding/decoding in LabView? Hello J,
in the example given here , it looks like a format simple bytestream...
You must read the byte stream, get the first and the second byte to decode the data type and length and then read & catalogued according to number of bytes. And then read 2 bytes and so on...

If you haven't done so already, take a look at the action of com.vmware.libarary.soap.processOutParameters. It is the action that generated the log you have placed in us. It generates an object Properties (key, value pairs) with the value for each setting that results.
In your case, assuming that 'outProps' is the result of the above, you can use:
var getRequestStatusResult = outProps.get ("GetRequestStatusResult");
And to analyze the code XML with E4X as Ilian said.

How to enable the end user determine the type of sort?
Helllo all,.
I use APEX 4.2.2. Oracle 11.2.0.3.
In a classic Rerpot (line custom model), how to allow the end user to determine the type of sorting?
I use decoding to select the column that the sort is done, but how to determine: Asc / Desc?
order by decode(:P2_SORT, 'PRICE', v.PRICE, 'PROP_SIZE', v.PROP_SIZE , 'BEDS' , v.BEDS , 'AREA' , v.AREA)
Kind regards
One way may be to use a second element which maintain the sort order. Lets call it P2_ASCDESC.
Your order by condition might look like this:
order by decode(:P2_ASCDESC,'ASC', decode(:P2_SORT, 'PRICE', v.PRICE, 'PROP_SIZE', v.PROP_SIZE , 'BEDS' , v.BEDS , 'AREA' , v.AREA), null) asc ,decode(:P2_ASCDESC,'DESC', decode(:P2_SORT, 'PRICE', v.PRICE, 'PROP_SIZE', v.PROP_SIZE , 'BEDS' , v.BEDS , 'AREA' , v.AREA), null) descI don't like this solution, since you réimplémentez one of the nicer features that apex was already out of the box. Better would be to stick to a classic report template and allow the standard user-defined sort order. Why do you think that you need your own non-standard solution?

Based on http://forums.Adobe.com/thread/1308132?TSTART=0 I decided to add each question separately:
Hello, I am very interested in buying Lightroom 5.2. I tried the RC that was missing today. Yet, I have several questions that I can't find really good conclusive answers, I'd like to get an answer before buying LR. Please do not write maybe like this or that (assumptions), because I don't want to start my entire workflow and then realize that I have to change all around, please reply, if you know for sure that something works and you are, preferably, using this method too.
Is the big question, where I want to especially a conclusive answer: How to manage the photos Lightroom when using 2 computers, keeping all the changes made on one of them, using the same photos for editing. I'm not going to use DNG. Details: I mainly use my old MacBook Pro, but I wish I could use my PC as it is much better (card: i5 2500K, 16 GB of RAM, SSD, USB3, nVidia GTX 560 TI etc.). I have 2 external HD that I could use, one for backup and one for the actual Photos/changes. I you will probably need to use as my internal HDs are fairly complete and I cannot be the kind of things simply delete or move to one (developer, without loss of music, programs etc.).
On this basis, how do I save all such Photos folder (pictures and retouching and preferably presets too)?
According to me, that it should be possible to work cross-platform without having to create a link to the files each time, or without having to keep export/import of the catalog, keeping the single catalog and the picture library on an external drive that is then switched between systems as needed.
Obvious first requirement is an external drive that is formatted in a way (for example, FAT32) that it can be used on both platforms in read/write mode. Given that, if the catalogue AND folder parent si le catalogue ET le dossier parent images are both set to the same level in a global parent folder, then it should be possible to take advatage of ability of Lightroom to use relative paths instead of absolute paths to detect the images, no matter if the player is named (Mac) or lettering (PC). This is how "export as catalog of ' works, that is, it creates a 'package', alias a parent folder, containing the catalog and a replica of the folder hierarchy to exported along with the catalog images. Take this 'package' to another system (same OS or not) and "it works" even if the drive letter is different or the operating system is different... because the relative path of the image catalogue is always the same.
I have not tested this cross-platform (if I have between various PC systems with letters of different readers) so for me it's still just a theory, but there may be others who have done this successfully.

How to manage the selection with the box in a table
Hello
JDev 11.1.2.4
I have a table with an attribute of EO/VO, transitional to manage the selection. This attribute is displayed as a check box. The user makes a selection by clicking on the checkbox. Then, the user clicks on a button that displays a pop-up window. Inside of this pop-up window, that user can create, insert, delete, or update values in a table based on an other EO/VO.
When the user clicks OK, the pop-up window is closed, then the data is committed.
When the user clicks Cancel, the popup is closed and the changed data are ignored. To remove the data, I call a Rollback. It works fine, but all the transitory values are lost which is correct because of the discount after the cancellation.
It's a problem because the user must be able to open the pop-up window several times with the same selection. This means that the restoration is not appropriate in this case.
How to ignore data edited inside the pop-up window and keep the selection?
Thank you
You can try to put the popup in his own taskflow and define a backup point before entering the taskflow. When the user cancel the editing restore you to previous backup. This should dispel the changes.
Or you save the selected rowkeys, call rollback and backward selection later.

How to manage the pause embedded inside the CSV column line
Hello
I'm under pressure to make it work. I've already put this question on the forum of the APEX, but on reflection, I think that it relates more to PL/SQL rather than APEX APEX 4.1 having already utility to manage the Upload of CSV.

I'm sorry for that. Thanks for reading.
I need to develop an application that allows the user to upload a CSV file to a table of interface.

I used the code of
http://dbswh.webhop.NET/HTMLDB/f?p=blog:read:0:article:11000346061523
It all works fine until recently I find
If a column in a CSV file cotain a break line (or line spacing) for example (the tester copy and paste this text which has a line break on a column in a spreadsheet)
It is the first sentence.
It is the second sentence.
It will break the 'it's the second sentence In a new column.
The contents of the CSV read next to Notepad as below
Date of assessment, Date, assessment provider, name of the assessor, Court, first name, middle name, last name, PRN person record, NHI number, assisted defendant Y/N number, is dependent on O/N, Notes, primary of ethnicity, "the ethnic origin other, please specify", gender, currently in treatment O/N, another Substance, Substance of concern 5 specified

Question about how Oracle manages the Redo logs
Hello
Assuming a configuration which consists of 2 redo log groups (groups A and B), each group of 2 disks (disks A1 and A2 for Group A) and B1 and B2 disks for Group B. Additionally, assume that each redo log file resides by itself in a disk storage device and that the device is dedicated to her. So in the situation described above, there are 4 discs, one for each redo log file, and each disc contains nothing other than a redo log file. Also, assume that the database is in ARCHIVELOG mode and the files from archive is stored on another different set of devices.
kind of graphically:
The question is: when the disks that make up the Group A are filled and Oracle switches to the disks in the Group B, can the group drives to take offline, perhaps even physically removed from the system if necessary without affecting the functioning of the database? Can the archiver process temporarily delayed until the disks (which have been removed) are presented online or is the DBA have to wait until the end of the process to archive a copy of the redo log file creating in archive?GROUP A GROUP B A1 B1 A2 B2
Thank you for your help,
John.Hello
A journal of the groups fallTo remove a group of online redo logs, you must have the ALTER DATABASE system privilege. Before you delete a line redo log group, consider the following precautions and restrictions:
* An instance requires at least two groups of files logging online, regardless of the number of members in the groups. (A group is one or more members.)
* You can delete a group of newspapers online redo only if it is inactive. If you need to drop the current group, first force a log switch occurs.
* Make sure a group of online redo logs is archived (if archiving is enabled) before dropping. To see if this happens, use the view LOG V$.SELECT GROUP #, ARCHIVED, STATUS FROM V$ LOG;
GROUP # ARC STATUS
--------- --- ----------------
1 ACTIVE YES
2. NO CURRENT
3 INACTIVE YES
4 INACTIVE YESDelete a group of newspapers online redo with the SQL ALTER DATABASE statement with the DROP LOGFILE clause.
The following statement drops redo log group number 3:
ALTER DATABASE, DROP LOGFILE GROUP 3;
When a group of online redo logs is deleted from the database, and you do not use Oracle managed files, operating system files are not removed from the disk. Instead, control of the associated database files are updated to remove members of the Group of the database structure. After deleting a group of online redo logs, make sure the drop completed successfully and then use the command of operating system appropriate to delete the dropped online redo log files.
When you work with files managed by Oracle, the cleaning of operating system files is done automatically for you.
Your database will not be affected as you can work with 2 files, redo log in each group, as the minimum number of redo log in a database file is two because the process LGWR (newspaper writer) writes in the redo log in a circular way. If the process crashes because you have 2 groups only if you want to remove 1 Add a third and make that the current group and remove the one you want to be offline.Please refer to:

How to manage the threads for TCP communication?
Hello
I have a project to control two separate applications (C++ and LabView) and two of them are implemented as server. Another client program (C++) is used to control applications. Communication between them are implemented using TCP socket. The client program sends the message to start or stop tasks on servers. The client program also sends time (HH) with the message start and end to determine when to start or stop.
Application in C++ (server): Listening to the request for the connection and when gets one, it creates a thread of communication allowing to manage this and listen again to another connection. Communication wire crossing of handles and messages when it receives a start or a stop message, it creates a thread of timer with the received time to trigger a task at the time specified. And after that he expects the client message. So, here, when the thread (communication, timer) is necessary, it is created.
In LabView (server): I tried to create the same as the C++ server. But, in manual of LabView and other discussions of the forum, I got that LabView is multithreaded and it can be done with the help of the loop independent. So, I had to create four loops in a diagram:
1. wait the new connection
2 manage the communication for the already received connection
3. start the timer
4 stop the timer
and they are executed at the beginning of execution and communication between them are managed using local variables. But, 2, 3 and 4th loop can handle only one connection and it can handle another if the current is closed. The C++ application can handle multiple connections by creating the thread when it is necessary, but not at the beginning of the application.
Is there a better way to implement this in LabView?
Is it possible to manage multiple connections and create the diagram node/block (such as a wire) dynamically as C++?
Thank you.
There are several ways to do so in modern LabVIEW and you should probably seek the Finder example for TCP examples. The classic is to transfer the refnum of connecting the listening loop in a communications loop that adds to an array of login credentials and then constantly iterates through this array to make the communication. He works on LabVIEW 4.0 perfectly for me even for applications with basic HTTP communication protocol. But you must make sure that the communication for a connection is not delaying his work for reasons that would delay the handling of other connections too, because they are really of course worked on sequentially. If you encounter an error, the connection ID is closed and removed from the table.
The other is that create you a VI that makes your entire communication and ends on an error or when the order quite. Make this reentrant VI and then launch it through VI server as the instance home, passing the refnum of newly received connection form the listening loop. Then use the method to Run let start and operate as an independent thread.
For all these, you should be able to find an example in the example Finder when searching for TCP.
