Best way to distribute configuration values to subVIs

I have a main VI with ~10 subVIs, all of which have a number of default constants embedded. I want to change my architecture so that all the constants are moved to a single ASCII text file which is not changed during program execution. I'm trying to decide the best way to do this:
- Read the file every time a subvi is opened (this is frequent).
- Use the "Read Key" function (this may be essentially the same).
- Read the file once at the beginning of execution, and store the values in a cluster which is passed to each subVI.
- Read the file once at the beginning of execution, and store the values in several clusters, passing only the needed values to a given subVI.
- Read the file once at the beginning of execution, and store the values in a functional (LV2) global which is read by each subVI when it is called.
I think all of these would work, but what would be the most efficient in terms of programming time, execution time, memory usage, and ease of future modification? I'm leaning toward the multiple clusters approach so that I'm not constantly reading a file each time a subVI opens.
Thanks to all,
James

Consider using what I call a "manager" VI. Its purpose is to manage the file for you.
You call it whever you want to know one of these parameters.
It knows whether it's read the file yet or not. If not, it does so on first call.
After that, it simply keeps all your values in its own memory (shift registers).
When you call it, it simply gives you the value(s) out of its memory, either as a big cluster, or as separated values.
That way, you only read the file once.

Best way to extract XML value wiith an xpath

Hello,
I wonder what is the best way to extract text value from XmlType with an xpath.
I need to insert a row inside a table where the row's data come from xpath extractions of an XmlType. I do a lot of (approximative 20) :
EXTRACTVALUE(var.myxmltype , '/an/xpath/to/extract/elem1').
EXTRACTVALUE(var.myxmltype , '/an/xpath/to/extract/elemI').
EXTRACTVALUE(var.myxmltype , '/an/xpath/to/extract/elem20').
inside the insert statement
Is this way is the best or is there a more optimal way ?
For example extracting the node '/an/xpath/to/extract/' and sarting from this node extracting "elem1", ... , "elemI", "elemN" children.
Thanks for your help,
Regards,
Nicolas

Hi Nicolas,
The answer depends on your actual storage method (binary, OR, CLOB?), and db version.
You can try XMLTable, it might be better in this case :
SELECT x.elem1, x.elem2, ... , x.elem20
FROM your_table t
   , XMLTable(
      '/an/xpath/to/extract'
      passing t.myxmltype
      columns elem1 varchar2(30) path 'elem1'
            , elem2 varchar2(30) path 'elem2'
            , elem20 varchar2(30) path 'elem20'
     ) x
;

What is the best way to distribute your swing application:

I have developed a application that connects to data base and it containes the functionality to manage the invoices and receipts system, but i am scare to distribute it by building it to jar using the netbeans build option , it runs fine but when i extract the jar file back i m scare that any one can easily decompile it using JAD and get the database credentials , please tell me the best way to distribute the application so that reverse engineering the application will not be possible please tell me that :(

Decompiling is unnecessary. All somebody would have to do would be to sniff the transmissions between your application and your database; the credentials are sent unencrypted.
So the problem is not that somebody could find out the database credentials, the problem is that your database exposes itself to the internet. And if anybody does find the credentials through any method at all, then you've got a problem.
And by the way if you distribute your application with the credentials hard-coded, then that makes it difficult for you to change the password if it does get compromised, because then nobody can use your application any more. This is a bad thing because one of the first things you should do when your system is compromised is to change the access password.
So really the best way to distribute this application would be to write it so that it connects to an application which runs on your server. This server application would communicate with the database, which would make it unnecessary for the database to be visible from the internet. Your Swing application would communicate with the server application via some kind of web service protocol.

Best way to get the values of local variables

What is currently the best way to get the values of local variables. I know it is not currently possible to set watchpoints on local variables, but what are the best workarounds?

You have to use StackFrame methods, eg, visibleVariables and getValues. To get a StackFrame for a thread, that thread has to be suspended, eg, by a BreakpointEvent.

Best way to distribute LabVIEW Instruments Drivers.

Hello,
I'm trying to stick to the standards described just there:
Developing LabVIEW Plug and Play Instrument Drivers
Instrument Driver Development Tools and Resources
Instrument Driver Guidelines
However, I cannot see clearly what is the best way to distribute the LabVIEW Instruments Drivers, except that I need to be compliant with those standards to be on the IDNET (Instrument Drivers Network).
Here is a couple of questions I'm not really sure about their answers:
Is it okay to use a .NET dll and to make some calls?
Is it fine to hide the Block Diagram? With passwords in the Drivers
Can we put prevent the modification
In my situation several devices (or let's say modules can controlled through one communication medium), so basically I might have one instrument drivers for several things.,,
May I use some OOD? In order to control the equipment with methods and set some properties and encapsulate the communication stuff in classes, some equipments could be consider are inherited from others (more recent for instance), or this is totally prohibited by the guidelines above?
What is the most suitable Specification Build type: Packet Library or other? If packed library, how to handle the early version created issue when opening the lib with newer version of LabVIEW then?
How to deal with the copyright thing, do I need to copy and paste the copyright on both the Front Panel and on the Block Diagram?
Is this copyright enough: "Copyright (c) <Company Name>. All rights reserved"?

Not sure about 1) but 2) and 3) are definitely a no go if you want your library to be distributable through the ID network. The standard only allows for DLLs in that are really developed in C but would require you to also distribute the C code as far as I understand.
OOP may not be a problem.
Packed Library is definitely not something you want to do. They only work in the LabVIEW version in which they were created. You will hate the moment you decided to go with packed libraries as requests come in for other LabVIEW versions and your drivers are bashed on all discussion forums as being a pain in the ass to use.

Best way to change TreeMap value?

Hello,
I am wondering what is the best way to change a value in a TreeMap? I have retrieved a value by .get on the key i.e.
String aString = (TreeMap) aTreeMap.get(aKey);but would now like to change aString and ?.put? it back into the map?
How would I do this?
Thank you,
Poot.

but would now like to change aString and ?.put? it
back into the map?Do I just have to keep a note on the (key,value) - especially key - change the value and then .put(key,value) back in? Though I'll need to remove the initial pairing if I do this since TreeMap won't allow duplicate keys!
There must be an easier way as this.
Thank you for your reply,
Regards,
Poot.

What is the best way to implement default values stored in a DB table?

[JHeadstart 10.1.3 build 78]
[JDeveloper 10.1.3 SU4]
We are struggling on how to best implement default values that are stored in a DB table. What we have is a database table with (CODE_TYPE, TABLE_NAME, COLUMN_NAME, DEFAULT_VALUE) as columns. This way the application administrator can administer default values himself/herself. Now we need to find the best way to set these table supplied default values in new rows. Globally we are aware of two ways:
- override create() method on VO
- probably create a View Object on top of the database table with default values (we are capable of transposing the table and return exactly one row with a column for each default value) and use JHeadstarts item property 'Default Value'.
We prefer the latter, since this is more declarative, however we struggle with the EL expression needed to indicate the default value.
If we have a VO named "DefaultValues" with a SELECT on a view on top of our database table (transposed) returning exactly one row, let us say:
SELECT orglanguage, orgtype, orgstatus [...]
FROM v_default_values
--> returning exactly one row
and we want an EL expression on an item that needs the value from orglanguage. What will the EL expression be? Something like:
#{data.DefaultValuesPageDef.currentrow.orglanguage.inputValue}? We tried several things but they do not work. A static default value works, but every EL expression so far does not. We know that using "data" can be dangerous, but thought JHeadstart takes care of preparing the other Page Definitions, so it might be possible when you use JHeadstart.
Or is overriding the create() method the preferred way? Or do we have to look at a Managed Bean for our default values that we refer to from EL (let us say MyAppDefaultValuesBean) and in that case: how do you associate a Managed Bean with a VO?
Any help would be appreciated. Apart from these default values, things are going rather well in this first J2EE/JHS project for us!
Toine

Steven,
Thanks for the reply. Unfortunately whatever we try, we cannot get it to work. We started looking at the second option (since we do need default values also in table lay-out new rows). We created a DefaultValues ViewObject, added it to the Application Module, added an EL expressiona to the Default Display Value property (replacing your ending ")" with a "}" offcourse ;-)), ran the JAG so that a page definition was generated for DefaultValues and we managed to get it prepared when loading for example the Organisation's jspx page. However no default value appears in a new row (not in Form, not in Table layout).
I then created a quick application on top of the HR schema, added a DefaultValues ViewObject using one calculated attribute (set Salary fixed to 1000), added the EL expression to the Salary Default Display Value property in the Employees Group, made sure the DefaultValuesPageDef is prepared by adding it to the parameter section and I see it getting prepared. I also see a managed Bean is created in the Employees-bean.xml.
In the Embedded OC4J log we see:
16:01:01 DEBUG (JhsPageLifecycle) -executing onCreate
16:01:01 DEBUG (JhsPageLifecycle) -CreateEmployeesDefaultValues bean found, applying default values to new row
2006-08-02 16:01:01.825 WARNING [ADFc] Warning: No Method onCreateEmployees and no actionBinding CreateEmployees found.
Is it this warning we should be worried about? Since no default value is created.
The managed bean (Employees-beans.xml) looks like:

We do not understand what is wrong and why the default values do not get created in the new rows (and it is taking us far too much time). Any chance the EL expression is still wrong? It is a shame that any syntax errors in EL expressions are not visible in some logfile. It looks like when EL expressions are wrong, they are ignored instead of raising an error...

Best way to use return values in a webservices

Hi all,
Scenario: We have three web services. What is the best way to do this acitivity or is it possible?
webservice1
webservice2
webservice3
Call invoke webservice1 & 2 (they need to their work do be done parallely and will return a value eg "string")and call webservices3 with input values as the returned value from webservice 1 & 2.
Thanks,
Shashi
Edited by: Shashi_sr on Sep 17, 2010 1:46 PM

Hi Shashi,
The way to achieve your desired functionality is as follows:
Create a flow activity, and within that flow activity, you will call web services (using an invoke activity) webservice1 and webservice2.
After the flow activity, you will then use another invoke activity to call the 3rd webservice using the output given by the first 2 webservices.

,          s.major_seq_nbrThis gives me a bunch of descriptive statistics on some data stored in the database, broken into groups by the time period.
I have 7 sets of possible values for the column wctr_id that are groups of similar/same work centers, and should be treated as the same, assuming the ord_nbr, sub_ord_nbr, and major_seq_nbr are the same. In my example case statement above, anytime I find 'H211' or 'H212', I am replacing it with 'Z211', which is my new, unique identifier for any wctr in the group ('H211', 'H212'). I have 7 of these sorts of groups that need to be replaced by a new, unique identifier. Is my CASE statement (noted above) the best way to do this, or is there a better way? These groups of similar-to wctr_id's are not listed in a table anywhere.

Hi,
As always, thanks for posting the CREATE TABLE and INSERT statements; that's very helpful, and leads to faster, better solutions.
Another thing that is helpful, and promotes faster, better solutions, is to simplify your problem.
For example, you have to compute a lot of aggregates, but it looks like you already know how to do that. This problem only involves the CASE expressions, and how they interact with the GROUP BY clause. So just cut out most of the aggregate functions.
Also, it looks like the intricacies of in-line view a have nothing to do with your current problem. For purposes of posting this problem, pretend that a is a regular view, so it doesn't clutter up the main query.
I think your problem could be restated like this:
You already have a query like this:

Is that a fair description of the problem?
For starters, you can use column aliases in the ORDER BY clause. Unfortunately, that's the only place where you can use column aliases in the same query where they are defined . You can compute them in a sib-query, and then use them in super-queries.
In other words, wouldn't it be nice if we had a table just like op_detail, but with an additional column called wctr? Make a view: either a regular view (especially if wctr, computed the same way, will be used in several different queries) or an in-line view, as shown below.
Wouldn't it be great if there was a table that was just like a, except that it had time_period alreay computed? Make a view: either a regular view or an in-line view, as shown below.

;In your example, wctr is the same as wctr_id except for two values. If it was more complicated (e.g., if there were not just 2 values that need to be mapped to 'Z211', but also 3 values to were equivalent to 'Z987', and 1 that was to be treated like 'A012', and 5 that should appear as 'A666', and ...), then you could code all that in a humongeous CASE expression (a nested CASE expression, if it involves more that 128 branches), but it really belongs in a table, where you have the raw wctr_id (like 'H211') in one column, and its corresponding equivalent (such as 'Z211') in another. I know you said you can't create new tables; I'm just pointing this out so you can tell the people who won't let you create new tables that it's a bad idea, likely to cause errors and certain to waste time in the future.

Best way to store 36 values

Hello,
I need to store 6 types of values with combination of 6X8 values totally 288 value .
For Example
1[{1,2,2,59,7,8,9,6},{1,2,2,59,7,8,9,6},{1,2,2,59,7,8,9,6},{1,2,2,59,7,8,9,6},{1,2,2,59,7,8,9,6},{1,2,2,59,7,8,9,6}]

How can i store these values in c# ?,which is the best way with respect to performance and security.
And whether i can store these data's in separate class file and access at time of process which is a multi-threading process.
If i asked any thing wrong sorry as i am new in these things.
Thanks

Best way to load configuration

Hi All
I've developed an application and I want to give my client the possiblity to change some configuration data (paths, languaje, etc).
Which is the best way to store this kind of data and wich is the best way to load it ?
I don't want a simple book or manual reference. I'll appreciate words of experience wisdom.. :)
Thanks in advance
<jl>

It used to be through java.util.Properties, but
I've found the java.util.preferences classes to
be almost too easy to use - pretty sweet stuff! (And
that should be enough hints for you right there...)I'll read preferences tips in API reference.
Thanks.

Best way to export configurations? FIM 2010

I can export for example management agents, but what is the best way to export for example sync rules or workflows?
Am I somehow able to export configurations to xml? Also what is the best way to export configutarions if I want to attach those to a word report?

Hello,
Yes, you can export Sync rule and Workflow into xml, with the powershell snap-in.
You will need to use
Export-FIMConfig and then ConvertFrom-FIMResource.
You can find some usefull scripts

Best way to check boolean value

Hi!
I have a schema defining an XML element with a boolean attribute. The document related to this schema use true/false literal boolean values, eg:
<myelement myattribute="false"/>....<myelement myattribute="true"/>
The data is stored in binary xml storage.
I query the db on the boolean attribute with an xpath condition like this:
..../myelement[@myattribute=false()]
Querying the db with this method:
SELECT XMLQuery('....' returning content) from dual
all works as expected.
Instead, using:
SELECT XMLQuery('....' ' PASSING OBJECT_VALUE RETURNING CONTENT)
FROM "myxmltable"
WHERE XMLExists('....' PASSING OBJECT_VALUE);
I get the error: ORA-31038: Invalid hexBinary value: "false"
To get the second query method working, I have to change the xpath condition, forcing a string comparison:
..../myelement[string(@myattribute)="false"]
Can someone explain me this behaviour? What is the best way to check a boolean value? I'd like to write the same xquery working in both methods!
Thank you.
Bye
Mirko

Hi Geoff

and here two sample XML documents:

<tns:ThirdChild>
<tns:ThirdChildA A="aaaa" B="bbbb" />
<tns:ThirdChildB C="cccc" D="dddd" />
</tns:ThirdChild>
</tns:MyElement>
I registered the schema using Enterprise Manager. The "Show SQL" function returned this script:

local => FALSE,
gentypes => FALSE,
genbean => FALSE,
gentables => TRUE,
force => FALSE,
owner => 'EMILIAROMAGNABUY',
OPTIONS => DBMS_XMLSCHEMA.REGISTER_BINARYXML);
END;
This is my test script:
-- This works fine: returns only the requested row.
SELECT XMLQuery('declare default element namespace "http://OracleTest"; collection("/Testing")/MyElement/SecondChild[@B=true()]' returning content) from dual;
-- This raises the error = SQL Error: ORA-31038: Invalid hexBinary value: "true"
select xmlquery('declare default element namespace "http://OracleTest"; /MyElement/SecondChild[@B=true()]' passing object_value returning content).getclobval() from "MyElement";
-- This doesn't work correctly: returns the requested row and two empty rows ?!? I don't like this cast, anyway.
select xmlquery('declare default element namespace "http://OracleTest"; /MyElement/SecondChild[string(@B)="true"]' passing object_value returning content).getclobval() from "MyElement";
Thank you

Best way to select distinct values based on another column?

I have a table with three columns: id (NUMBER), data_dt (DATE), and data_value (NUMBER).
There is a primary key on id and data_dt.
I want to select the record with the latest data_dt for each unique id.
What is the best way to do this?
I have three different methods, but there may be something I am missing.
First:
SELECT *
FROM
SELECT id, data_dt, data_value,
         FIRST_VALUE(data_dt)
         OVER (PARTITION BY id ORDER BY data_dt DESC) AS last_data_dt
FROM the_table
WHERE data_dt = last_data_dt;(I use ORDER BY...DESC instead of just ORDER BY so I don't need the ROWS BETWEEN clause)
Second:
SELECT t1.*
FROM the_table t1
JOIN
SELECT id, MAX(data_dt) AS last_data_dt
FROM the_table
GROUP BY id
) t2 ON (t2.id = t1.id AND t2.data_dt = t1.data_dt);Third:
SELECT t1.*
FROM the_table t1
WHERE t1.data_dt =
SELECT MAX(t2.data_dt)
FROM the_table t2
WHERE t2.id = t1.id
);-- Don

Hi,
There are more possible scenario's, for example:
select t1.*
from   the_table t1
where not exists ( select null
                   from   the_table t2
                   and    t2.data_dt > t1.data_dt
What is the best way to do this?Only you can tell:
Test all scenario's, check the execution plans, set timing on and pick the best/fastest one ;-)
If it's not clear, please post the execution plans here.

Best way to throw custom error from SubVI

Hi
I was wondering how best to throw error messages from a SubVI.
Say I have a toplvl VI called Caller.vi which calls Sub.vi. The toplvl vi whishes to use the Sub.vi's error out cluster to determine what to do - e.g. halt execution of the toplvl vi if the Sub.vi throws an error. Easy enough if the Sub.vi just have to pass errors from build in LabView functions and VI's, but how to do it if the sub vi has to throw a custom error upon some condition?
Say the sub vi takes a certain number of inputs and that the inputs need validation before executing what ever the sub vi does. E.g. a certain algorithm implemented is only meaningfull if a>10.
My own thought is this: Simply select between an empty/no-error error cluster and an error-cluster containing the wanted custom errorcode and description. The area circled in blue is the interesting part:
Is that the worst idea you've iever seen implemented?
The only other real suggestion I've been able to find (which originally adresses another issue, but shows a method for "throwing an error") is a VI posted in this thread: http://forums.ni.com/t5/LabVIEW/Throw-an-error/m-p/882575 which looks like:
Please help me out guys How to throw a custom error which is not intended for the end-user, but intended to ease the life of a develper calling the sub-vi if he/she wishes to.
Best regards
Wuhtzu

Thank you tbob. (EDIT: and thank you blawson)
I know all about volunteering and having jobs to do - I participate in quite a few fora. I just thought that my topic was lost since after only 2 days it was on page 3 of the forum - but if page 3 isn't forgotten I will remember that next time and also if 2 days isn't patient I will also remember that
To you answer: The error code should be negative, shouldn't it? Even though an indicator wired to error-out of a build in labview function will actually display error codes as positive... maybe it's diffrent form labview version to labview version. My v2010 manual reads:
"You can define custom error codes in the range of -8999 through -8000, 5000 through 9999 or 500,000 through 599,999"
So say I want to throw an error with error code 5687 - should I then wire -5687 or +5687 to the cluster?
Thanks - Wuhtzu
