Binding a variable to a shared variable is taking the attributes of that variable?
Is it possible that binding to a shared variable to have the attributes of that variable? With other words shared variable shares attributes also?
Thank you,
Virginia
I builed a vi server that prepears data to be updated to an interface and data has all type of attributs such as color, background and foreground, and for this reason I wanted to be able to be updated with attributs.
I will give up to have like an updated control in my interface but to updated it from the server with detailed attributs in a continous loop instead.
Data with attributs give me not only the value but the status also.
Thank you!

Front Panel Mass Binding Project Variables Issue
Hello -
When attempting to bind controls to shared variables through the front panel mass binding option, there is an issue where you can not seem to bind a "project item" to the control. The method of binding I am using is to export a text list of control names, urls, mode, and function to a text editor utilizing the front panel binding mass configuration options. The text editor shows, in the fourth column, a "0" for no function, a "1" for network item, and a "2" for project item. when attempting to import the list back into the front panel binding mass configuration, all "2" indications become "1", as all items are treated as network. Thus one can not effectively bind to a project shared variable item.
The binding works fine manually by means of utilizing the properties selection of the control, but it is difficult to do this for 821 controls, as in my application.
My application is based on a OPC served group of 821 variables which are linked to controls and indicators through the shared variable representation for each item created in the multiple variable editor.
Does anyone have a work around for this issue, as it is a showstopper right now, ie, you can not effectively bind a large quantity of controls or indicators to project located shared variables as required.
The rationale behind utilizing project located variables instead of network located variables is to reduce the amount of calls to the OPC server which was causnig a large latency in the refresh of the 821 items. With the items defined as shared variables within the project, a single call is issued, which has tremendously sped up the refresh cycle for the list of variables.
Thank you in advance for your insight in this matter,
John DeCroosHello Brian A.,
In response to you comment --
"in 2006, and John did not follow up with any more information for Efosa"
-- a great deal of information was provided to NI (Efosa and many, many others, up to the product manager for the DCS module). I have never heard back on a fix for this bug for the identified version of LabVIEW. The reply by Efosa here was well after we had shipped our product -- (please see date + Efosa's apology) -- we had found our own solution as is identified in the original post.
My solution was, as is also indicated in my original post, to manually bind each variable. This was unbelievably time consuming, but was all I had.
The version of software I am now working on uses far less variables, manually bound to avoid the multiple binding issue we had in the past.
I have checked the mass binding function in LV 8.5.1, it works fine now. I guess it would have been nice to have had a reply that the bug had been resolved ---- would have helped me out a bit.
Thank you,

How to bind DATE variables in SQL*Plus
I have a stored procedure in a package that has a DATE OUT parameter
myPackage.myProcedure( outDate OUT DATE )
I am trying to test this from SQL*Plus
How do I specify a Bind variable for the outDate? The VARIABLE command does not allow DATE types?
If this was a CHAR type I could have done
VARIABLE myChar CHAR
BEGIN
myPackage.myProcedure( :myChar )
END;
PRINT myChar
How do I do this with DATE data types instead? I am using Oracle 8.1.7.you should use VARCHR2 type with the minimum length that can store a value defined by your NLS_DATE_FORMAT
string. The returned date will be converted to a VARCAHR2 type and the size and format will depend on
your NLS_DATE_FORMAT setting.

Queries not working with multiple bind position variables?
still need help here - can anyone provide any direction?
(note: this is a follow-up from prior topic, " How to use JDBC Positional Binding Style & ExecuteWithParams?")
I created two simple view objects off of the same entity
object to perform this test:
#1 - ViewObject with one bind position variable - where clause: where id > ?
#2 - ViewObject with two bind position variables - where clause: where id > ? and id < ?
I created two separate .jspx pages, view1.jspx (one input field) and view2.jspx (two input fields), for each view object by dragging ExecuteWithParams operation onto the JSF page.
The .jspx page with one input field works (returns result sets.) The view2.jspx page with two input fields does not work - the query does not return any result sets (no errors produced, it just does not return any rows) - I've tested my query outside of jdeveloper and it works fine. I also tried switching my inputs to make sure I did not have an illogical query (i.e., id >100 and id< 1).
Is there anything different / extra I need to do to use two bind position variables?
Everything in this simple test was identical except for using 2 input variables versus 1.
Technology stack is: jdeveloper 10.1.3, jsf/ADF BC, mySQL 5.01
Message was edited by:
javaXUsing the where clause: "where id > ? and id < ? for the 2 input variables, I get the same result - no row results returned (though query works outside the browser.)
Interestingly, I modified the where clause to where between ? and ?, and then used values of 1 and 100 to test. Using the BC4J tester, the query gave back a single row with id = 100 (should have brought back 100 rows because there are 100 records with ids 1-100.) So I got it to return something, but not the right results. This makes me believe that a different query is being sent to MySQL other than what I'm expecting from what is shown in the SQL Statement of the View Object..
Is there anyway to view what SQL statement is actually being sent to the database using the BC4J tester? Also, could this be an issue related to the mySQL connector drivers and JDeveloper? Im using mysql-connector-java=3.1.11-bin.jar (10/10/2005)? First though, if I could see what query is actually being sent, this may help me to debug and figure out the problem. -

Any help will be much appreciated.
iI guess I should use DBMS_SQL.BIND_VARIABLE to bind all variables seperately so not to mess with query1) What is the error you get?
2) If you use bind variables inside a query, you should prefix them with colons, so use :l_cur_year_from etc.
3) Why are you using dbms_sql instead of native dynamic sql and/or ref-cursors?

Hi all,
How can we bind a variable if the column name exists in another
table.
For ex.
I have two tables lets say tab1,tab2. The tab2 holds the
column names of tab1.
table structure and data is.
tab1
id col1 col2 col3 col4
1 234 sysdate 3233 334.93
2 235 sydate 345 33.42
tab2
id inv_no date vendor
1 col1 col2 col4
2 col3 col4 col5
based on these two table values, I have to build a variable.
ex.
l_var = 234 ||sysdate||334.93;
And every time in my table 1, I will have at least 50 to 70k
rows. How can i do this. Please help me any one.

Code above will work if I remove everything about the 'output' variable
To test I would like to put in data for a column that is too large, have all other rows inserted, but return the row that had bad data. Thanks for any thoughts on this-I have a similar issue, i.e. the pl/sql table type as out parameter is causing probleml in one API related to Oracle Applications. I have singled this problem out by creating wrappers and testing them against BPEL process. Now as soon as I put an out parameter with pl/sql table in my wrapper, I start getting errors. Why the invoke even care about what is in output while calling the API? How can I get rid of it. I am not able to pin point where exactly you made the changes. Could you please share some more info or possibly share the BAD and GOOD code.
We will probably get away with this by creating just a wrapper that would have NO out parameter as PL/SQL table as I don't think we need it anyway.
Still want to know what is the issue here as we would like to avoid any custom wrapper creation?

How can a variable display the first character that's on the page?
I'm creating a telephone directory and want each page to display the alphabet of the first listing on the page on the top - only one character.
Can you tell me how to do this?Hmmmmm, seems I was wrong about the GREP styles. I just tried it and they don't get picked up. I consider that a bug, but it's probably "as designed."
That leaves you having to work with nested styles only, or Find/Change. I think what you'll need to do is redefine the Paragraph style so it has two nested styles that apply the correct style to whatever needs to be styled at the start of the paragraph, one for the first character and the second for the rest of the word(s) if you can figure out a trigger (can InData add an end nested style character or is thew some punctuation you can use?), then find/change to remove the applied character style. For that I'd serach for ^.+ with the find format set to the character style that InData applied and the chane format set to [None], which will only remove it from the beginning of your paragraphs. If this is done correctly there will be no change in appearance since the redefined paragraph style will do the formatting.
If that won't work, you can use find/change to apply a new style to the first characters. Search for ^. and set the change format to the new character style that you'll use in the variable. It needs to have the same attributes as the style applied by InData or the appearance will change.
The second method is probably easier since you don't need to redfine the paragraph style, but both methods require you to use find/change to alter the text, which means if more text is added you'll need to re-do the find/change. Not a big deal, but don't forget. I'd be tempted to wait until the last minute and just ignore the headers for the moment, if editing is ongoing. I'd also test this on a copy of the file for safety. -
How can I use a shared library made with the application builder?
Hi,
I am using LabVIEW 7.1 running on Slackware 10.1 (kernel 2.4.29) and I am trying to call a graph display from a C program that I use for debugging VME access from a VMIVME controler. So using the application builder I built the VI as a shared library (graph.vi -> graph.so) containing a function called "graph". In my main program the call to the dlopen fails with the error: "graph.so: undefined symbol: UninitLVClient". When I examin graph.so with nm I see that UninitLVClient and other LabVIEW functions are indeed undefined and using ldd shows that graph.so has dependencies only on libc.so.* and *linux*.so.* but not on LabVIEW related stuff. Those functions are defined in the liblv.so that's in the cintools directory but I have no idea if the user is supposed to use that.
So I think I am missing an important concept here. Can somebody help or direct me to some documentation (I found lots of information about how to link external code to LabVIEW but nothing about how to link LabVIEW code to an external program)?Thanks Watermann,
your message has been very useful so now I am linking to the proper library but I still have problems when trying to load dynamically the shared library produced with LabVIEW. It is strange that I could successfully load the lvrt library at loading time but it does not work when I am loading the library at execution time.
I made a small LabVIEW program that prints a hello window and I am calling it from a C program. In the first program main.c I am linking to the lvrt library at loading time and it works but in the second one I am linking dynamically at execution time and it does not work. For my work I need to be able to load code done in LabVIEW at execution time. Any help is appreciated!

hello();
printf("Bye ... \n");

This is happening to me also but only with certain apps. The message I get with the apps that won't update is "Update Unavailable with This Apple ID. This update is not available for this Apple ID either because it was bought by a different user or the item was refunded or cancelled".
