Advanced Programming Techniques?

I recently learned about dynamic programming, and it's really helping me with programming contests and such.
So I'm just wondering if there's anything else like dynamic programming that I've never heard of. I don't know what you call them, "techniques" was the best I could come up with.
Thanks.

It doesn't quite answer my question though--I can find information on stuff if I know what to look for. I just don't know what to look for.
I've heard of linear programming and read a little, but are there any other..."foo programming" techniques? What are these things called anyway?
Linear programming isn't a programming technique at all; it's a class of mathematical problems.
Rather than tracking down "foo programming" techniques, I'd say your best bet is to educate yourself about algorithms in general.

LabView programming techniques

Hello,
Can anybody recommend me some links/documents/papers where several LabView Programming Techniques are presented?
I know LabView (I think that pretty good) but I've learned it by myself. And now, I have to do some (small-average size) projects that are not for personal use. So I would like to know how can I improve my VIs in order to be easily modified, debugged, tested, structured etc. If you can also recommend me some LabView tools/features that could help me to build "professional" LabView projects and VIs I would be thankful to you.
Thank you,
Paul

In addition to Ray's recomendations I'd also suggest you serach this site for "Design-Patterns" and become familiar with those (if you have not already).
I also posted a number of Nuggets on programming techniques as well that can be found in this thread of Nugget links.
If all of that info is "old-news" then try your hand at responding to questions here on the forum, and others will let you know how you are doing.
(another point! if your code resembles any of the examples found in this thread, you may want to re-think your techniques.
Now if you get through all of that and really want to test yourself against the best LV developers in the world, you can try your hand at answering Q's on LAVA (LabVIEW Advanced Vitual Architects).
Just trying to help,
Ben

"Advance Synchronization Techniques for Data Acqusition is not simple.

I want to use a 6534 DIO to drive my instrument and a synchronized 6502E to do AI from the instrument. The developer zone tutorial "Advanced Synchronization Techniques for Data Acquisition" suggests some of what is necessary to change from using AO as the master to using some other operation. After installing an RTSI cable, "Synchronized AI,AO,DI,DO,CTR.vi" runs as-is. Has anyone successfully converted the "Synchronized AI,AO,DI,DO,CTR.vi" or something similar to having some other master than AO? I want to use DO as master, and have moved the start vi's to the initialization cases except that for DO, have removed DI completely,and have tried to get DO to transmit REC1 on RTSI1 and AI and AO to clock o
n the RTSI1 signal. The modified VI runs to completion, but I get no input at AI.

Hi Bhanu,
I ran the program SAP_FACTVIEWS_RECREATE.It is also not fetching any data.In the monitor, the extraction shows yellow status and the Processing says NO DATA.I have not given any selections at infopackage level.
Please let me know what do i do.
Thanks in advance.

Advanced Development Techniques for Oracle Portal Components

Hello friends,
I have the following problem. I have a report and a form (on a
view) in the same page, and when I select an item of the report
the form is refreshed with the values associated to the selected
item. The problem is that it makes it with delay, the first
selection doesn't show anything and the remaining sample the
data of the previous selection.
This application has been developed as Ken Atkins explains in
its document "Advanced Development Techniques for Oracle Portal
Components."
Oracle Portal Version: 3.0.9.8.0
Thanks in advance.
This is my code:
-- REPORT --
SELECT '<A HREF="http://mipc/portal30/
ALFONSO.refrescar_contenido?
p_variable=nombre_preferencia&p_variable_valor='||nombre_preferen
cia||'&p_pagina=61">'||Preferencias||'</A>' nombre_link
FROM ALFONSO.PREFERENCIAS
-- PROCEDURE TO REFRESH THE PAGE --
CREATE OR REPLACE PROCEDURE refrescar_contenido(p_varible IN
VARCHAR2,
          p_variable_valor IN varchar2,p_pagina IN
VARCHAR2) IS
v_Sesion portal30.wwsto_api_session;
BEGIN
v_Sesion := portal30.wwsto_api_session.load_session
('CONTEXT','SESS_EMP');
v_Sesion.set_attribute(p_varible, p_variable_valor);
v_Sesion.save_session;
owa_util.redirect_url('http://mipc/servlet/page?
pageid='||ppagina||chr(38)||'_dad=portal30'||chr(38)
||'_schema=PORTAL30'||chr(38)||'_mode=3');
END;
-- FORM --
-- ... BEFORE DISPLAYING THE PAGE
alfonso.consulta_preferencia(p_session);
-- PROCEDURE consulta_preferencia --
CREATE OR REPLACE PROCEDURE consulta_preferencia(p_session in
out PORTAL30.wwa_api_module_session) IS
v_RowID VARCHAR2(100);
v_Session portal30.wwsto_api_session;
v_nombre VARCHAR2(40);
BEGIN
v_Session := portal30.wwsto_api_session.load_session
('CONTEXT','SESS_EMP');
v_nombre := v_Session.get_attribute_as_varchar2
('nombre_preferencia');
IF v_nombre IS NOT NULL THEN
BEGIN
     SELECT rowidtochar(rowid) INTO v_RowID
     FROM ALFONSO.VISTAPREFERENCIAS
     WHERE nombre_preferencia = v_nombre;
-- VISTAPREFERENCIAS it is the view in which the form is
based.
END;
-- Tell the component that the query is coming from a link,
and that the rowid
-- is being used to query the correct context record.
p_session.set_value (p_block_name=>'DEFAULT',
p_attribute_name=>'_CALLED_FROM_LINK'
               ,p_value=>'ROWID');
-- Pass the rowid of the context record to query.
p_session.set_value (p_block_name=>'DEFAULT',
p_attribute_name=> '_ROWID'
               ,p_value=> v_RowID);
-- Now do the actual query, using the query button
processing in the target module
portal30.wwa_api_module_event.do_event
('DEFAULT','QUERY_TOP',1,'ON_CLICK',True,'',p_session);
-- Save the session information, which includes the
p_session.save_session;
END IF;
END;
/

You can make the report with a procedure from which you may call to a form by means of a link. It is a possibility, no??
It is better a example:
TABLE A
campo1 VARCHAR2 (20)
campo2 VARCHAR2 (20)
CREATE OR REPLACE PROCEDURE REPORT IS
v_cursor NUMBER;
sentencia VARCHAR2(200);
vnumfilas NUMBER;
rowid_pref VARCHAR2(18);
v_campo1 <schemaname>.A.campo1%TYPE;
v_campo2 <schemaname>.A.campo2%TYPE;
BEGIN
     htp.p('<HTML>');
     htp.p('<HEAD>');
     htp.p('</HEAD>');
     htp.p('<BODY>');
          sentencia := 'SELECT rowidtochar(rowid), campo1, campo2 FROM A';
          DBMS_SQL.PARSE(v_cursor,sentencia,DBMS_SQL.V7);
          DBMS_SQL.DEFINE_COLUMN(v_cursor,1,rowid_pref,18);
          DBMS_SQL.DEFINE_COLUMN(v_cursor,2,v_campo1,20);
          DBMS_SQL.DEFINE_COLUMN(v_cursor,3,v_campo2,20);
          vnumfilas := DBMS_SQL.EXECUTE(v_cursor);
          LOOP
          IF DBMS_SQL.FETCH_ROWS(v_cursor)=0 THEN
                    EXIT;
          END IF;
          DBMS_SQL.COLUMN_VALUE(v_cursor,1,rowid_pref);
          DBMS_SQL.COLUMN_VALUE(v_cursor,2,v_campo1);
          DBMS_SQL.COLUMN_VALUE(v_cursor,2,campo2);
          v_link := '<A href="PORTAL30.wwa_app_module.link?p_arg_names=_moduleid'||chr(38)||'p_arg_values=<form's moduleid>'||chr(38)||'p_arg_names=_rowid'||chr(38)||'p_arg_values='||rowid_pref||chr(34)||'>'||campo1||'</A> '||campo2||' <BR>';
               htp.p(v_link);
            END LOOP;
     htp.p('</BODY>');
     htp.p('</HTML>');
END;
the form has to be based on the table A.
I dont know if this example has errors, but have you the idea??
I hope it helps you out.

Use UTF-8 all the way. During both request and response processing.
More info: [http://balusc.blogspot.com/2009/05/unicode-how-to-get-characters-right.html].
Edit: I should add, you should in no way do ugly things like myname = new String(( myname.getBytes("iso-8859-1")), "Big5" );on request parameters. Just get the parameter and that's it. The parameter should already be properly encoded if you follow the instructions in the aforementioned article.

Advance programming in pl/sql

hi
everybody
can anyone suggeste me book for advance programming in PL/SQL.
plz write author name and book name.
ur advice always appricated.
thanx

This may be difficult to answer because what one person would call "advanced" to another would be called "beginner" or "intermediate".
Have you looked through the Oracle PLSQL user guide and the Supplied Packages guide? these show how to use PLSQL and how it has been extended to cover a vast array of functionality

Logo advanced/master techniques in Illustrator

I've been using Illustrator and learning an immense amount in the program, but I know that there are still things I need to learn when it comes to designing logos.
Here's a link to my portfolio work on 99designs:
http://99designs.com/users/618210/folio
Based on what you see in my portfolio section (without being rude ); what advanced/master logo techniques should I learn?
I am well aware that there are many Illustrator tutorials online (like http://vector.tutsplus.com/) but in terms of actually creating better logos; what techniques should I learn? (Like letterpressing effect or sticker effect technique)
**And No I'm not interested in how bad crowdsourcing is for the designer; I mainly joined to learn and hone my skills and it's working. **

Your logos are uninspired, which is not an issue of specific techniques, but rather a problem with design. They just are what they are - knock-offs of other logos and it shows. If I may say so: Turn off the computer, have a little fun with pencil, ink and paper, scribble away. Then explore how you could transfer those designs into the digital world and learn the necessary techniques along teh way. Or, IOW: You are hampering yourself too much by thinking about how to do things before even knowing what to do, which limits the exploration of your own creativity and developing your own style.

New Enterprise Manager Book on Advanced EM Techniques for the Real World

Dear Friends,
I am pleased to say my first EM book can be ordered now.
Oracle Enterprise Manager Grid Control: Advanced Techniques for the Real World
[http://www.rampant-books.com/book_1001_advanced_techniques_oem_grid_control.htm]
Please let your colleagues and friends and clients know – it is the first book in the world to include EM 11g Grid Control. It is a great way for people to understand the capabilities of EM.
Oracle’s Enterprise Manager Grid Control is recognized as the IT Industry’s leading Oracle database administration and management tool. It is unrivalled in its ability to monitor, manage, maintain and report on entire enterprise grids that comprise hundreds (if not thousands) of Oracle databases and servers following an approach that is consistent and repeatable.
However, Enterprise Manager Grid Control may seem daunting even to the most advanced Oracle Administrator. The problem is you know about the power of Enterprise Manager but how do you unleash that power amongst what initially appears to be a maze of GUI-based screens that feature a myriad of links to reports and management tasks that in turn lead you to even more reports and management tasks?
This book shows you how to unleash that power.
Based on the Author’s considerable and practical Oracle database and Enterprise Manager Grid Control experience you will learn through illustrated examples how to create and schedule RMAN backups, generate Data Guard Standbys, clone databases and Oracle Homes and patch databases across hundreds and thousands of databases. You will learn how you can unlock the power of the Enterprise Manager Grid Control Packs, PlugIns and Connectors to simplify your database administration across your company’s database network, as also the management and monitoring of important Service Level Agreements (SLAs), and the nuances of all important real-time change control using Enterprise Manager.
There are other books on the market that describe how to install and configure Enterprise Manager but until now they haven’t explained using a simple and illustrated approach how to get the most out of your Enterprise Manager. This book does just that.
Covers the NEW Enterprise Manager Grid Control 11g.
Regards,
Porus.

Database Adapter Advanced Polling Technique

I would like to create a polling database adapter on an SOA application. The data is statistical and changes frequently. I have developed the SQL in sqldeveloper to get the data (hard part done, or so I thought). I would like the adapter to poll the database with this query and fetch the results. I plan to use a sequential table to keep track of the fields at a separate database. Now, I understand I could turn the SQL script into a view and have the database adapter poll the view. However, my requirements are that the process be as unobtrusive to the database as possible. In other words: they do not want me to put that view on the database. So, my question is: has anyone created a database adapter polling mechanism that can execute a pure SQL select statement such as the one i have created. Of course, the SQL script is rather complex and it cannot be implemented using the TopLink commands on the database adapter wizard in jDeveloper. Does anyone know of a way i can do this? and if so, how? Thanks in advance.

Could you provide more insight on how you wired the adapter and BPEL process inside the composite? What does the BPEL look like? You could add a BPEL component that persists some stuff just for test purposes. That could give you more feedback from the console.

ADF - Best programming technique

Hello,
I am new in ADF BC and ADF Faces. I see there are many techniques how to do something and I'm little bit confused. For example I have adf jsp with backing bean behind it. I want to decrease adf table column "itemCnt" value by 1 when a button is clicked.
How should the button action code look like?
1. itemCnt.setValue(new Integer(itemCnt.getValue().intValue() - 1));
2. use bindings: find my iterator, getCurrentRow, getAttribute, setAttribute
3. write the code into Entity or ViewObject implementation class and invoke the method
4. or should I try to use JSF expresion language?
Thank you.
Rado

Hi,
in this case option 1) seems to be the choice. Setting the component value should also update the business service, so no need to call teh VO directly (makes no sense to call the EO for this at all).
Using EL is a matter of taste, but since you have a bacing bean i don't see why you shouldn't use it

Advance Reporting Technique from Calendar Link

I have created a calendar with a namelink, and am trying to link the namelink from a certain date to a dynamic page that displays further information about the event on the date. I have a description column in info table which has the information. What is the proper context in SQL for displaying only the information for the date clicked. I figure I need to use a where statement? Do I have to pass the date parameters to achieve only the display the data for that date?

any suggestion?
Thanks

How do I get audio output from a labview program

We are modifying an existing labview program that reads data from a BNC-2140 DSA and displays as a graph. We want to be able to stream audio in audible range instead of a graphical display. Is there a VI available that can create audio? If not, how can I go about creating one?
Thank you

Hey Lost-
There is a wonderful document on our external website that groups our knowledge on using sound with LabVIEW.
Under the LabVIEW Resource Library (http://zone.ni.com/libraries/) choose -> LabVIEW -> Advanced Programming Techniques -> Using Sound.
This page lists over 5 examples for playing sounds with LabVIEW through WAV, MP3, and other formats. Streaming audio might be tough, depending on your processor. It might be hard to translate your input into a format LabVIEW can play. I am not sure what sound format that input data you refer to would be. This will be a good starting point. Also, I have heard of a Microsoft ActiveX control, DirectShow, that might help you. I have not worked with this guy, but I would check into it at Microsoft's site -> www.msdn.
microsoft.com.
Post again if you have follow-up questions.

Display image for BLOB Download link in Interactive Report

I have a table containing BLOB data and am displaying the table in an interactive report. I would like to replace the "Download" text link with an icon that represents the MIME type of the BLOB, but can't seem to find a way to make the substitution. Does anyone know how to do this? Thanks.
-Jeff

Hey Ben,
Thanks for the suggestion. I understand what you are saying, the problem is that when you have an interactive report that includes a BLOB and you use the built-in method for displaying a download link, it only gives you the option of using a text link. The method is outlined in the online help under:
Home > Advanced Programming Techniques> About BLOB Support in Forms and Reports > About BLOB Support in Reports
This is done by using the following syntax in the Number/Date Format of the column attribute of the BLOB:
DOWNLOAD:CC_DOCUMENTS:CONTENTS:ID::MIME_TYPE:FILENAME:UPDATED_ON::attachment:View
Where the last parameter is the link text. The only problem is that there is no option for substituting an image rather than the link text. That's what I'm trying to work around. Sorry if you new all of this already, but I wanted to explain what I've already done. Thanks for any help you can offer.

Can anyone recommend a Fixup to change any Pantone names in a PDF from C to U?

Hi I have tried running several pre-flights and fix-ups to analyse a file and change the colours within a PDF from either Pantone "C" to "U" or "U" to "C". It seems to flag a warning in the pre-flight but when I try to use a fix-up to change the names and colours it says that no issues were found and in the output preview of the Plates they remain un-changed. Any ideas ??????
Regards
Tracy

There are several ways to do this.
It seems to me that the easiest would be via SQL toolkit. Then you can open your database in LabVIEW and write directly to it.
You have to use ODBC Source administrator or the equivalent to define a global definition of the data source. Use a system DSN to describe / define the path to the Access database you want to write into.
I'd like to find out how to programmatically change the db file to which the DSN points to. Right now, I use one System DSN to point to an Access db and copy over the db file the specific db I want to use at the time.
Another way is to use Access as an ActiveX server, from LabVIEW.
We have two VBA books here, plus of course the VBA on-line documentation and the LabVIEW on-line help and examples. The Ac
tiveX chapter in the book "LabVIEW Advanced Programming Techniques", Bitter, et. al. and the ActiveX examples in the LabVIEW help were the most helpful. I was trying to interface a LabVIEW executable app, an ActiveX server, with Excel VBA though. Using Access as the ActiveX server may or may not be easier. Again there are SOME good examples. The specific version of Access you have may expose different properties and methods than those shown in the examples, however, so you have to be careful.
