When I use Call Library Function Node in real time, is the DLL loaded once for all or load every time it is called?

When I use Call Library Function Node in real time, is the DLL loaded once for all or load every time when it is called?
I have a time critical real time application, in which I use a piece of DLL function developed by C++. It is OK? Could any senior developer assure me?
Thank you in advance.
Solved!

OK
Be sure that all DLL calls are thread safe (do not perform calls in UI thread).
Also for real-time application you need real-time OS.

Is it possible to call a function when a specific event happens?

Hi everyone,
I would like to pop up an alert when a user deletes a named destination marker. I thought this would be a no-brainer, but I'm having trouble finding examples of scripts that handle events.
Is this even possible? Any ideas on how to go about this would be greatly appreciated.
Thanks,
Heather Ayer
PS - I always say this when I post, but many thanks to all who contribute to this forum. I'm still learning and don't post much, but I read each question and answer. So, thanks!

Thanks, Rick!
Your info was very helpful. I did consult the list of “monitorable” events and deleting an anchor is not on the list. But, it’s good to see what is available for future projects.
I was trying to prevent deleting of a single anchor, but instead I’ll move on to the next component of comparing all the anchors to a .csv file. I know I’ve seen posts about this before. So, I’m off on another fact finding mission.
Thanks again,

Call contact at a specific time

Hello, is it possible to to make a calender-entry to call a contact at a specific time and when remembered by the calender-notification to perform the call out of the calenderapp-note?

No, it is not.

How to call the function 5 times

hi
i have a function 'a' with array 1x2, 1x3, 1x4...
every step its 1x2 > answer
1x3 > answer..
ans so on
if answer correct i call my function 'a' again.
how i can call my function 'a' just 3 times?
thank you.

Hello!
Well, it depends on some factors, like:
1) Function 'a' itself checks if the answer is correct?
2) Which event calls function 'a'?
... and so on.
Please, if you could detail your problem and maybe post some code, it will be easier for us to understand it and help you :-).

Calling Remote function tool leads always to a logon screen

Hello,
I run an remote function tool in system A. In System B I run a report calling this function module.
Each time, I execute the report, a remote logon screen appears. It looks the same like the one you logon the system. You have to specifiy client, user and password.
I know one possibilty to avoid this logon screen appeaering.
System B (holding the function module) must declare System A as a trusted system. Thus, the user does not need to logon system B, each time calling the func. module. I processed this in correspondence with the help data, but the screen still appears.
Is there any other possibilty to avoid appearing the logon screen or does anybody know wheter I did something wring??
thanks, holger

Hi Holger,
1. This has to do with tcode SM59 (Maintain RFC Connections)
THE CALLING SYSTEM HAS NOT DEFINED
USER ID / PASSWORD TO LOGON TO THE TARGET SYSTEM.
HENCE, IT SHOWS BLANK LOGIN SCREEN
2. Under the node RFC Destinations ---> R/3 Connections,
various systems are defined for RFC Purpose.
3. Lets say ur system(which u want to connect) is PRD.
4. Double Click PRD and go the the details.
5. There are 3 Tabs. Goto LOGON/SECURITY TAB.
6. In the logon information , enter the
USERID and password and client.
7. Save.
Then try your program.
Hope this helps.

Amit Mittal.

Office specific time

hi people,
here is the script of a trigger......it is supposed to update a column called mod_date to the office specific time date and pull the latest row which was modified.......
i am not able to understand the script completely can anyone guide me,i am not able to unserstand why we r declaring lv_sysdate as office_sysdate().can't we just capture the office specific time using TIMESTAMP with LOCAL TIME ZONE
DECLARE
lv_sysdate DATE;
BEGIN
     IF USER = 'gkljhg ' THEN
          RETURN;
     END IF;
     lv_sysdate := Office_Sysdate('');
     :NEW.mod_datetime := lv_sysdate ;
     :NEW.mod_userid := USER;
     IF INSERTING OR UPDATING ('con_name') THEN
     :NEW.con_search := UPPER(:NEW.con_name);

Server side function not get called after dispatching cairngorm event second time on same page

Hi All,
I am facing a urgent issue regarding cairngorm event. Actually my page contain 3 button add,delete,save
and clicking of any button I do the respected functionality. For ex:
I click the add button & on clicking of add button I fire a cairngorm evnt & after getting response from server side that the record is added
I displayed a message that the record is added & update the data source.
After addition of the record , with out going to other page if I perform the same functionaly(Like adding another record) on same page the cairngorm
event not call the server side function - after debugging I find out that cairngorm event reach to the corresponding excutecommand function & called that function but it is not calling my server side function & I also din't get any error message .
I dont know why the server side function not get called?. similarly if I try for delete or update case the same things happend. Only for the first time it works properly but not for the second time.
Could any of you please tell me why the cairngorm event not calling the server side function.
Thank you for your kind assistance.
Regards,
Ujjwal

Okay, well I think I've worked out the problem.
In ASP.NET we would typically bind repeating controls such as DataLists and Repeaters manually using <i>Control</i>.DataBind(), because we're usually using a separate class library containing collections for our objects. Seems the SAP Table control doesn't like this approach.
I changed the code so that the databinding is specified on the control, and call the Page's DataBind() method and it all worked fine.
One tip: because the collection I used to bind to is in a separate class library, I receieved a <i>BC306523: Reference required to assembly MyAssemblyName...</i> message, even though I had a reference to the assembly in my project and the DLL is being properly deployed. To fix this, you must include the following directive at the top of the component's ASCX file:
<%@ Assembly Name="AssemblyName" %>

Execution time for Call Library Function Node

I am experimenting with the Call Library Function Node block in LabVIEW and am curious if it should be running faster than what I'm seeing. For testing purposes, I have compiled and transfered to my RT target the .out file from the KB article http://digital.ni.com/public.nsf/allkb/81D1172E3C28A5E4862575CC0076A230 (I'm using the vxworks 6.1 version). The function in the .out file just multiplies two inputs together, adds a constant, and returns the result. I have put this inside a 1 kHz timed loop with a commanded period of 1 ms and via the Ticks(ms) block and shift registers I calculate the amount of time per loop execution. This process is apparently taking 5 ms per cycle and to me that seems slow. Is that roughly the correct execution time for this kind of setup? I will attach my test .vi file.
What I'm using:
Windows 7
LabVIEW 2009 SP1
NI-cRIO 9024 with NI-RIO 3.4.0
Solved!

First off, the way you are doing timing isn't necessarily accurate because you don't know when the tick count VI is being called. For example, if it gets called on one iteration after your call library node executes, and the next iteration it gets called before the CLFN it executes, the subtraction doesn't include the call of the CLFN so you aren't seeing the true time it is taking for the dll to be called.
Where it says "error" on the top left hand corner of your loop. left click and choose previous iteration timing. Also, do you have the ability to choose a 1 Mhz clock? Are you sure it's actually being run on the RT and not on your PC? Running it on the PC would definitely make it difficult to execute at a 1 kHz rate.

Can call a function a few times in reports

Hi
Please help me to solve this problem:
I have a function taking parameters and return a number, I tried
2 ways to call this function but get same error saying the
function may not be used in SQL:
1. the function is in a package, and I use the pl/sql query
(build from data model) to call it a few times by passing
different parameters, I get error when compile the query
2. the function is outside the package, and is called from
another function in the package a few times, get error when
compile the package body.
3. by the way is weekly typed ref cursor allowed in reports?
Below is part of my code:

RETURN NUMBER;
END;

function diemSum (
party_id IN NUMBER,
partytype IN NUMBER,
fid IN NUMBER,
freeday_type IN VARCHAR2,
startdays IN NUMBER,
enddays IN NUMBER)
RETURN NUMBER IS
pdSum NUMBER(10);
BEGIN
IF partytype = 1 THEN
IF freeday_type = 'gateout' THEN
SELECT COUNT(*) INTO pdsum

party_code := :partycode;
          freeday_type := :freeday;
          OPEN sum_cv FOR SELECT      f.facilitycode,
               perDiem.diemSum(p.partyid,
p.partytypeid, f.facilityid, freeday_type, 1, 4 ) as days1,
          perDiem.diemSum(p.partyid, p.partytypeid,

          FROM equipmenttrip et,
               facility f,
               facilitysegment s,

     WHERE f.facilityid = s.facilityid
          AND p.partycode = party_code ;
     RETURN sum_cv ;
end;
case 2 *** diemSum is a seperate function from package
create or replace package perDiem AS

freeday_type IN VARCHAR2)
RETURN curType;
END;

RETURN sum_cv ;
END diemDet;
END;

My bet would be that the function doesn't promise not to update
the database. Therefor it can't be called from a select statment.
To overcome this you need to define a pragma. I don't remember
its exact name but I think it is restricted_reference.

Can I call a specific time of the timeline in an advanced action?

Can I use the specific time of the time line to trigger an advance action? If I can what is the correct syntax to call the timeline information?
eg:
in a conditional advanced action
IF
Timeline - is equal to or greater than - 00:16
AND
Timeline - is less than or equal to - 00:20
ACTION
Show - Image 21
ELSE
Hide Image 21

Double post, see: Can you add Advanced actions to an image?
My list with system variables will not really help, I'm afraid. My suspicion (and yours in the other thread) is that the OP doesn't understand the design of the Timeline.

Call a function at specific intervals

Hi,
I need to call a function or page at specific intervals. Or I need a ping a page at specific intervals, to keep the session alive.
I found window.setInterval() works fine. Is there any such function in coldfusion?

put your function in a cfc and use cfschedule to call to that method. Example :
remoteCalls.cfc
<cfcomponent> <cffunction name="callMe" access="remote"> .. do stuff here .. </cffunction></cfcomponent>
Setup a scheduled task in coldfusion to call your url every X minutes :
http://www.domain.com/remoteCalls.cfc?method=callMe
If you have arguments, pass them in as url variables.

Is it possible to call a function with the same name from 2 different dll's at the same time.

I'm trying to call a function ( F ) form 2 different libraries ( A.dll and B.dll ) at the same time. The first lib loaded determines the function F. A->F and B->F have same interface and name but different implementation.

Hi,
I tried it with two dll's, both with the same interface, and at the same
time, in the same VI. The popups even appear at the same time.
But now I understand the problem... Both dll's are created by LabVIEW! If
they are not (or one is not, and the other is), this is no problem.
And VI's in memory cannot have the same name. LabVIEW doesn't care if VI's
are in a dll or not.
This might not help, but if you want to make some sort of "plug in" system,
you might consider using llb's. By loading VI's dynamically, you can select
the path from which they are loaded. You must unload (close all references)
one before the loading the other, or the same problem will occur. If you go
this way, I consider a different approach. Make on
e library (or even a dll)
that has the interface you like, this is the "loader". Now make several
"plug in"'s, with the same interfaces. The name of each function in a plug
in is a concatenation of the library name and the function name. The loader
has one extra function, that loads (and unloads, when done) references to
all desired libraries to use (the names of the functions can be figured out
easily). All that the loader functions do is dynamically call the library
functions. You can use a call by reference node for this (you can use the
connector pane or the loader vi, since the interface must be the same!).
If you go this way, I guess the loader library can be converted to a dll...
Hope this helps.
Wiebe.

Is there a way to see specific times and duration of phone calls?

Is there a way to see specific times and duration of phone calls?

Tap the phone button, then Recents. You see a list of the recent calls and can tap the arrow to the right of the name/number. That should give you the time and duration.

How can I debug the Call Library Function at run-time

I've written a VI using the CLF to call a DLL which was compiled off-site by another engineer using MSVC. Even though the VI runs without flagging any errors, the VI is not doing what I expect. Is there any way of finding out if the DLL is been called correctly? The first function that is called doesn't return any value, but I think that it should. Does this mean that the DLL is not being called correctly? Note also that the DLL works fine with a JAVA GUI.

Make sure that you are specifying the proper function prototype in the call library function. If you are slightly off the call will not work properly. Ask the offsite engineer to provide you with this data. Another tip is to build the dll with the option to show front panel when called. You can actually popup the dll like you would a subvi. If you design it with test indicators showing on the front panel that is a great way to determine if it is working. Hope this helps.
