How to use the add_line procedure of laf project

Hi all.
I'd like to use the add_line procedure of Laf project to draw a line at a specific place in a canvas. But there are several parameters and i can match the one i'm looking for.
I can for example, set how large, thick, color etc. that line is to be drawned. but indeed i, like to place it at a specific location within a canvas, say (56,31).
My current line of code is:
Set_Custom_Property( 'CONTROL_LAF.BEAN',1,'ADD_LINE','1,10,10,300,10,2,r154g106b58,.5,round,blevel');
Any ideas will be highly appreciated.
Regards, Luis ...!

Hello,
<p>Do you have the link to the documentation?<br>
You can specify only the first 5 parameter wich are: indice, x1, y1, x2, y2<br>
Set_Custom_Property( …, 'ADD_LINE', '1,56,31,250,31' );
</p>

How to use the Stored Procedure to update my UDF

I want to use the Stored Procedure to update my UDF U_InstokCS when the warehouse "OnHand" was changed. The UDF is display the stock by cases. I copied the query as follewing. I couldn't see any thing in the UDF after I made some transactions. Can anybody tell me why? How to continue it?
if @transaction_type in ('A','U','D') and @Object_type='64'
begin
Update OITW
Set U_InstokCS = OnHand/(Select T0.NumInBuy from [DBO].[OITM] T0
Where T0.ItemCode = @list_of_cols_val_tab_del)
Where ItemCode = @list_of_cols_val_tab_del
end
Thanks.

Ying,
The use of any stored procedures against the SAP Business One database is not allowed per SAP Support. There is not an instance where you can use SP's. The ONLY SP that you are allowed to use is the SBO_SP_TransactionNotification SP that comes with SAP Business One itself. You can read about the use of this SP from this article...

How to use the apply procedure for partial classification

Hi all,
I have used the Oracle data mining association rules (AR Apriori) to build a model which I filter out its rule to include only those where the consequent (RHS) is the class attribute. This enable me of producing partial classification rules set(associative classification) even though I have used AR model. The question now, I want to apply the module to test data using the APPLY procedure, however, AR unsupervised learning models are not supported in the APPLY procedure.. Any idea how I can over come this problem....
I notice that there are similarities between AR and K-means clustering algorithm, the question, can I convert an AR model into a clustering one?
Thanks in advance
F

The short answer is no. It is not possible to move the model content from one model to another. The only way to do that would be if you knew the internal representation of the models and could then change them directly. This information is not documented. If you managed to do that, you would not be able to get support if you run into problems with those models.
Out of curiosity, why you want to use AR to build a classifier instead of one of the classification algorithms in ODM? I have seen some work on associative classification. It seems that these approaches usually try to get around the greedy top-down nature of decision trees by first identifying regions (itemsets, rules) with reasonable frequency and then prune to create a classifier. The numbers I've seen were not very convincing for the extra work and ad hoc nature of those methods.

Using the Netbeans GUI within a Project with existing Ant Script

I cannot seem to figure out how to use the Netbeans GUI in my Project with existing Ant Script. Is this possible? I have no problem creating GUI interfaces in a java Application, but attempting to make a new JFrame Form gives the error: package org.jdesktop.layout does not exist, and I have not been able to find a way around this. Any suggestions? Thanks in advance.

How to use the procedure column in reports

Hi all
How to call the procedure in reports as source.. If possible how to use columns of procedure in the layout column of report????

Hi,
Your query is not clear.
1. In subject are you asking total column.
A. Edit pivot view and go to Rows and click Total BY option here you can find option like (none,before,after) the you can select after it will display total all culms.
2. I want use the columnC in columnD ? -- Am not understand.
A. What my understand is you want to see the report only C and D values only.
If it is correct we can apply filter in report level click column filed and apply not equal to A then it will show only C and D only.
If it is wrong pleas post me correct one with example. Will try to help out this.
I am not sure this is what your looking so far.
Award points it is useful.
Thanks,

How to use the default database service name on creating procedure for data

how to use the default database service name on creating procedure for datagaurd client failover ??? all oracle doc says create a new service as below and enable at DB startup. but our client is using/wanted database default service to connect from application on the datagaurd environment (rac to non rac setup).please help.
Db name is = prod.
exec DBMS_SERVICE.CREATE_SERVICE (service_name => 'prod',network_name =>'prod',failover_method => 'BASIC',failover_type => 'SELECT',failover_retries => 180,failover_delay => 1);
says already the service available.
CREATE OR REPLACE TRIGGER manage_dgservice after startup on database DECLARE role
VARCHAR(30);BEGIN SELECT DATABASE_ROLE INTO role FROM V$DATABASE;
IF role = 'NO' THEN DBMS_SERVICE.START_SERVICE('prod');
END IF;
END;
says trigger created, but during a swithover still the service is listeneing on listener.
tns entry.
prod =
(DESCRIPTION =
(ADDRESS_LIST =
(LOAD_BALANCE = YES)
(ADDRESS = (PROTOCOL = TCP)(HOST = prod1)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = prod2)(PORT = 1521)) ---> primary db entry
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = proddr)(PORT = 1521)) --> DR DB entry
(CONNECT_DATA =
(SERVICE_NAME = prod)
thanks in advance.
Edited by: 854393 on Dec 29, 2012 11:52 AM

Hello;
So in the example below replace "ernie" with the alias you want the client to use.
I can show you how I do it :
First an entry need to be added to the client tnsnames.ora that uses a SERVICE_NAME instead of a SID.
ernie =
(DESCRIPTION =
    (ADDRESS_LIST =
       (ADDRESS = (PROTOCOL = TCP)(HOST = Primary.host)(PORT = 1521))
       (ADDRESS = (PROTOCOL = TCP)(HOST = Standby.host)(PORT = 1521))
       (CONNECT_DATA =
       (SERVICE_NAME = ernie)
)Next the service 'ernie' needs to be created manually on the primary database.
BEGIN
   DBMS_SERVICE.CREATE_SERVICE('ernie','ernie');
END;
/After creating the service needs to be manually started.
BEGIN
   DBMS_SERVICE.START_SERVICE('ernie');
END;
/Several of the default parameters can now be set for 'ernie'.
BEGIN
   DBMS_SERVICE.MODIFY_SERVICE
   ('ernie',
   FAILOVER_METHOD => 'BASIC',
   FAILOVER_TYPE => 'SELECT',
   FAILOVER_RETRIES => 200,
   FAILOVER_DELAY => 1);
END;
/Finally a database STARTUP trigger should be created to ensures that this service is only offered if the database is primary.
CREATE TRIGGER CHECK_ERNIE_START AFTER STARTUP ON DATABASE
DECLARE
V_ROLE VARCHAR(30);
BEGIN
SELECT DATABASE_ROLE INTO V_ROLE FROM V$DATABASE;
IF V_ROLE = 'PRIMARY' THEN
DBMS_SERVICE.START_SERVICE('ernie');
ELSE
DBMS_SERVICE.STOP_SERVICE('ernie');
END IF;
END;
/lsnrctl status - should show the new service.
When I do this the Database will still register with the listener. I don't give that to the clients. That one will still be available but nobody knows about it. Meanwhile "ernie" moves with the database role.
So in my example the default just hangs out in the background.
Best Regards
mseberg

How to use a stored procedure as a datasource in Crystal Report for Eclipse

Hi All,
I've written a stored procedure in oracle 10g with few input parameters and one refcursor output parameter. I want to use this stored procedure as a data source for creating a report in "Crystal Report For Eclipse 3.6.0".
When I tried to add this stored procedure to the report using the connection explorer, I don't see any option to do this. But when I try to add any table, it shows options like "Add to the current report"....
Can anybody assist me how to use a stored procedure as a data source in "Crystal Report For Eclipse"?

FM-update of tax using the net procedure

Hi everyone!
How should the tax be updated in FM during payment of an invoice? I chose the net procedure and assigned a statistical commitment item to the tax account (the tax amount shouldn't spend the budget). When I post an invoice tax is updated to the statistical commitment item and the net value of an invoice to the correct commitment item of expenditure, but when I post a payment of that invoice it is updated in whole amount on the commitment item of expenditure...I don't know if this is correct.
Please help...

Doesn't anyone know answer to this question??? Is it really that hard? I can't believe that nobody used the net procedure regarding tax update before...

How to use the knowledge base category hierarchy?

Hi !
I read documents about the knowledge base, I know Oracle Text supplies English and French knowledge base, but I would like to know how to use it, how to handle it. If I want to had some themes, or delete some.
Is there a table containing the knowledge base?
Is there someone can help me? Thanks in advance
Have a nice day
PS : sorry for my poor english

Thank you very much M. Omar R Alonso for your reply.
I checked in the documentation how to use the ctx_query.hfeedback procedure, and I tried the example provided. But it doesn't work, the bt_feedback, rt_feedback, nt_feedback columms have never filled.
I'm not sure that the knowledge base is already supplied in Oracle Text, because also, when I execute a query like :
select ID_TXT, score(1) SCORE from TEXT_BASE where contains("idx_txt","sport",1)>1 order by SCORE DESC
The results are the same as
select ID_TXT, score(1) SCORE from TEXT_BASE where contains("idx_txt","about(sport)",1)>1 order by SCORE DESC
So, I don't know if it uses the knowledge base or not.
Thx again

How to use the same POWL query for multiple users

Hello,
I have defined a POWL query which executes properly. But if I map the same POWL query to 2 portal users and the 2 portal users try to access the same page simultaneously then it gives an error message to one of the users that
"Query 'ABC' is already open in another session."
where 'ABC' is the query name.
Can you please tell me how to use the same POWL query for multiple users ?
A fast reply would be highly appreciated.

Batch processing usually involves using actions you have recorded. In Action you can insert Path that can be used during processing documents. Path have some size so you may want to only process document that have the same size. Look in the Actions Palette fly-out menu for insert path. It inserts|records the current document work path into the action being worked on and when the action is played it inserts the path into the document as the current work path..

Okay so I set up my Time Capsule already and is now backing up 2 of my iMacs. Works great. What I want to know is how to use the TC to directly store files? I want to do this to delete some files but still have them on the TC for future reference..

Okay so I set up my Time Capsule already and is now backing up 2 of my iMacs. Works great. What I want to know is how to use the TC to directly store files? I want to do this to delete some files on iMac 20inch but still have them on the TC for future reference..eg some movies on iTunes. I want to directly save them on the drive so I can delete them from iTunes and gain some storage. (Ps on iMac 20 inch (it's almost full - 320 GB) when I enter time machine, a tab comes up on finder which reads "Time Machine backups" it's able to be ejected like a disc or a connected device. On the iMac 20 inch, I dragged some files onto there as if using it like a hard drive. Is this the correct method? Then I went to my 27inch iMac and saw the "Time Machine Backups" hoping to see the files I dragged from the 20inch iMac. But the files were not there except a folder that said "Backups.backupdb". Can someone help me?

It's not a good idea to use a network disk for both Time Machine backups and other things. By design Time Machine will eventually consume all the space on its output disk, which will then cause problem for your other files. I'd store those other files on an external disk connected to the Time Capsule. The problem with that is that Time Machine will only back up files that are local to your Mac. That means that you'll only have one copy of the files on or attached to your Time Capsule.
By the way, you've been misled by poor field labeling on this forum into typing a large part of your message into the field intended for the subject. In the future just type a short summary of your post into that field and type the whole message into the field below that.

JNI - How to use the error reporting mechanism?

I've developed a C++ DLL which is loaded from a commercial Win32 application (not written by me) as a plug-in for external calculations. On its initialization the C++ DLL launches the Java VM via the JNI invocation interface. When the DLL functions are called by the application, they forward the calls to Java objects inside the Java VM, again via JNI invocation interface.
This works well, but I have encountered a weird error.
From Java I open a JFrame containing a JTextArea as small console for debug output messages. If I turn output to this debug console off (my printToConsole routine checks whether a boolean flag is set), the string concatenation operator may lead to a crash of the Java VM.
For example, if in one of the Java functions called from the
DLL via JNI invocation interface the following is the first statement,
it leads to a crash of the Java VM and the application that loaded the C++ proxy DLL.
String test=""+Math.random(); // String test not used later
Interestingly, if I comment this statement out, the Java code works fine WITHOUT any crash. I've already thought about potential races and synchronization issues in my code, but I don't see where this is the case. And the string concatenation error fails as well, if I insert sleep() statements in front of it and at other places in the code. However, if I turn on log messages printed to my JFrame debug console (containing a JTextArea), the String concatenation works without problems.
So maybe the JNI interface has a bug and affects the Java VM; I don't see where my JNI code is wrong.
One problem is that I do not get any stdout output, as the C++ proxy DLL is loaded by the Windows application, even if I start the Windows application from the DOS command line (under Windows).
Does anyone know how to use the error reporting mechanism?
http://java.sun.com/j2se/1.4.2/docs/guide/vm/error-handling.html
Is it possible that the JVM, when it crashes, writes debug information about the crash into a file instead of stdout/stderr?
My C++ proxy DLL was compiled in debug mode, but the commercial application (which loaded the DLL) is very likely not.
I do not know hot to find the reason why the String concatenation fails inside the Java function called from the C++ DLL via JNI.

Yes, I've initially thought about errors in the C++ code too. But the C++ code is actually very simple and short. It doesn't allocate anything on the C++ side. It allocates a couple of ByteBuffers inside the Java VM however via JNI invocation interface calls of env->NewDirectByteBuffer(). The native memory regions accessed via the ByteBuffers are allocated not by my own C++ code, but by the program that calls my DLL (the program is Metastock).
The interesting thing is that everything works fine if output to my debug console is enabled, which means that in the Java print routine getConsoleLoggingState() returns true and text is appended to the jTextArea.
static synchronized void print(String str)
{ MetaStockMonitor mMon=getInstance();
if ( mMon.getFileLoggingState() && mMon.logFileWriter!=null) {
mMon.logFileWriter.print(str);
mMon.logFileWriter.flush();
if ( mMon.getConsoleLoggingState() ) {
mMon.jTextArea1.append(str);
Only if output to the JTextArea is turned off (ie. getConsoleLoggingState()==false), the crash happens when the FIRST statement in the Java routine called via JNI invocation interface is a (useless) String concatenation operation, as described above.
String test=""+Math.random(); // String test not used later
Moreover, the crash happens BEFORE the allocated ByteBuffer objects are accessed in the Java code. But again, if console output is turned on, it works stable. If console output is turned off, it works when the (useless) String concatenation operation is removed in the Java routine called from C++.
I've already thought about potential races (regarding multiple threads), but this can be ruled out in my case. It almost appears as if the JVM can have problems when called by the invocation interface (I tested it with Java 1.4.2 b28).
All the calls between C++ and Java go ALWAYS in the direction from C++ code to Java. Unfortunately, there is no special JRE version with extensive logging capabilities to facilitate debugging. And the problem is not easily reproducible either.
