VI Profiler on dynamic called VI archiecture
I have a question about debugging to put to the Gurus out there.
My architechure is this, Event driven Producer, which queues Data into the Primary Consumer Loop. Primary consumer Loop performs an action and Queues information into the Secondary consumer Loop which updates the front panel GUI.
The Primary consumer calls test VIs dynamically using a call by Ref node function.
I have a very simple test VI which I am repeatedly calling which is outputing the time since the whole test sequence started (in ms) to the Front panel.
For debugging I have put a conditional disable around the dynamic call function, and I can change it to call the test VI directly.
VI profiler is telling me that the execution of my run a test VI which does the dynamic call takes 0ms. This can't be true.
The results from VI profiler would indicate that I could run 20 tests in about 1 second, but it's taking me about 10 seconds.
I do 10 display updates (via property nodes to change the active row, colours and contents of a multicolum listbox) per test.
Any ideas how I should be debugging where the time is being lost? - VI profiler is not helping enough.
Cheers

Opening a dynamic VI takes time. Load ahead of time use it and when done close it.
1) Def FP updates (to shut of screen updates), hide the MCLB, update it, un-hide, un-defer. passing data directly to the MCLB via terminal is fastest but can't do color stuff without property nodes.
2) Pre-load
Ben
1)
And here comes the killer...
If I defer FP updates, the code runs slower!!! not faster.
If I change the MCLB from Synchronous to Asynchronous using the drop down menu before I run it has no effect on the run time.
If I change the MCLB from Synchronous to Asynchronous at runtime using at property node (not meant to do this), I get error 1073 and the GUI stops updating (sometimes while redrawing the screen half way down), but wiping over the FP window 10 seconds later shows the code has run significantly faster.
2) How do you preload 120 different tests all with the same VI pattern (generated from the same template) and ensure you have the correct VIs in memory without running them? (and producing loads of errors - these tests all logs any errors they produce to files)
I asked for the Guru's I didn't think I was going to the the Knights so fast!! Thanks Ben
Lacking Guru's you'll have to settle for me for now.
If the defer makes it go slower the issue may indeed be the FP updates since the defer forces an extra update when set.
Is is slower if do the next two steps of hiding updating and un-hiding?
If you toss all MCLB code does it run fast enough to make you believe it is the GUI update that is hitting you?
Can you post image of your code as png or jpg?
How much data is in the MCLB?
This cloud has links to LabVIEW_Performance threads. Not sure if any of those threads ring a bell.
Please show us the code to get the most out of us.
Not sure about Q#2 but I would open them and keep a ref to each in array so that they are loaded when I need to run them.

Here's the problem. Dynamically called VI becomes broken inside an executable in debug executable mode Error 1003 is occuring from "Open VI Reference" Block. The computer has all of the necessary drivers, NI-VISA and NI-DAQmx. This executable is a new release of software that currently works on the PC in question. I can using NI-VISA Remote Server control the instruments from my PC using the executable. But when I put the executable on the PC I am getting this error. The only way I have been able to get this to work properly is to build the executable from the console I believe the project was created in, note that the project file has been moved to a network drive and it still works. All of the stations I have opened the project in show the VI that is being called is runnable. I've tried building the executable from the console I am deploying to and the same thing happens.
I am honestly at a loss for ideas why this is occuring. Is this something about the way LabView works internally that may be causing this problem?
I have trolled this forum for idea's and none have made sense to me.
Any input would be greatly appreciated.
-NateTwo ideas:
Mass compile the project to ensure all linkages are ironed out
Include the dynamically launched VI's into the "Always Included" section of the build spec
Report back on if either of these actions solves your problem.

How to edit a program dynamically called from another program
Hi all,
Can anyone help me in coding for a program which call's another
report dynamically from selection screen(for instance z_dynam_called)
and retreive the whole content of the dynamically called program(z_dynam_called)
into an internal table and replace the contents of the internal table with some new code and put it back in z_dynam_called and save it.
Thanks in advance.
Needful will be rewarded with pointsHi,
Follow this:
1) U can pass data from one program to another in a single login using SAP memory......
2) u can create a DBtable update dat table using ur first pgm and fetch from second program.....
3) U can pass the report output using EXPORT TO MEMORY addition and get it back using IMPORT FROM MEMORY..........
Eg:
Export the selected rows to the next program
EXPORT final TO MEMORY ID 'ABC'.
CALL TRANSACTION 'XXX'.
XXX is the tcode for the other program where u want to import the values.
In the second program
INITIALIZATION.
IMPORT the internal table from the first program
IMPORT final FROM MEMORY ID 'ABC'.

Dynamic call for records in a table
hI,
Im having a ztable, the structure is as follows:
tabold fldold tabnew fldnew
The records in this table is are:
1.yvbap posnr xvbap posnr
2.yvbak auart xvbak auart
3.yvbak augru xvbak augru.
Now, i have to use this table dynamically to check each and every record in the program:mv45afzz.
So, my problem is that, i have to dynamically pass these records which contains table name and its field name.
i can write as: xvbap-posnr = yvbap-posnr for all the three records (the values will come from sales order tranx, report: mv45afzz)
but in future if the records are added then i have to again change the code, so this shouldn't happen.
It should dynamically call all the records in this table and check the condition.
Thanx
RohithHello Rohith
What is your question???
You described a few ingredients of your scenario (not all of them) and do not really explain your requirements.
Given the descriptions of the Z-table fields I assume you need to check whether OLD values are equal to NEW values.
If this assumption is correct then the solution is quite simple (except for XVBAP / YVBAP: Does this mean single entries or looping over all entries?)
DATA:
lt_ztable TYPE STANDARD TABLE OF zstructure,
ls_ztable TYPE zstructure.
FIELD-SYMBOLS:
<lt_tab> TYPE table,
<ls_struct_old> TYPE any,
<ls_struct_new> TYPE any,
<ld_old> TYPE any,
<ld_new> TYPE any.
" Read entries from z-table
SELECT * FROM ztable INTO table lt_ztable.
LOOP AT lt_ztable INTO ls_ztable.
ASSIGN (ls_ztable-tabold) TO <ls_struct_old>.
ASSIGN (ls_ztable-tabnew) TO <ls_struct_new>.
ASSIGN COMPONENT (ls_ztable-fldold) OF STRUCTURE <ls_struct_old> TO <ld_old>.
ASSIGN COMPONENT (ls_ztable-fldnew) OF STRUCTURE <ls_struct_new> TO <ld_new>.
IF ( <ld_old> = <ld_new> ).
" do something...
ENDIF.
ENDLOOP.
For the sake of simplicity I did not add the required statements for checking successful ASSIGN's.

Dynamic call for a ref cursor: ORA-21779
Hi,
Here is an environment:
create or replace
PACKAGE PKG_GETDATA AS
TYPE cursor_type IS REF CURSOR;
Procedure SimpleGet (cData In Out Cursor_type);
Procedure DynamicGet (cData In Out Cursor_type);
END PKG_GETDATA;
create or replace
PACKAGE BODY "PKG_GETDATA" AS
Procedure SimpleGet (cData In Out Cursor_type) As
Begin
Open cData For
Select 1 from Dual;
End SimpleGet;
Procedure DynamicGet (cData In Out Cursor_type) As
Begin
Execute Immediate 'Begin PKG_GETDATA.SIMPLEGET(:1); End;'
Using In Out cData;
End DynamicGet;
END PKG_GETDATA;
So- first simple get works fine:
Declare
cData PKG_GETDATA.Cursor_type;
aNumber Number;
Begin
PKG_GETDATA.SimpleGet (cData);
LOOP
FETCH cData INTO aNumber;
EXIT WHEN cData%ROWCOUNT > 5 OR cData%NOTFOUND;
dbms_output.put_line (aNumber);
END LOOP;
close cData;
End;
BUT dynamic call does not works at all!:
Declare
cData PKG_GETDATA.Cursor_type;
aNumber Number;
Begin
PKG_GETDATA.DynamicGet (cData);
LOOP
FETCH cData INTO aNumber;
EXIT WHEN cData%ROWCOUNT > 5 OR cData%NOTFOUND;
dbms_output.put_line (aNumber);
END LOOP;
close cData;
End;
It throws ORA-21779 exception; what is more- it does work on 10.2 db version but does not work on 11.2 version! Could anyone explain that?

Dynamic call of a vi with a reference stored in a global variable
Hello,
I am trying to program a VI which calls DAQmx functions in some cases, in other cases DAQmx may not even be installed. To prevent a broken arrow on machines where DAQmx is not installed, I want to use a sub-VI containing the DAQmx function calls which is called dynamically by a main VI. For speed I want to prevent continuous opening and closing the VI reference, so I want to store the reference to the sub VI in a global variable. In this variable I also want to store the Analog Input Task. I want to use an initialization VI to write the VI reference of the sub VI and to configure and start the Analog Input Task and write the Task ID to that Global, too. In that way I was hoping to be able to improve the performance of the dynamic calls and the Task calls. BUT - when I write the refererence and task to the Global and read it out from another VI, the reference is not valid anymore and the Analog Input task is also not valid, even if both the initialization VI and the Global are still open (but not running). Does somebody have an idea how to solve that? It is a bit difficult to describe, so here is what I want to do in a shorter description :
- run a initialization VI which
defines a reference to a sub VI which will be called dynamically later on
and a AI task ID definining a DAQmx physical channel configuration to use for subsequent read cycles
and writes both (VI reference and AI task) to a global variable
- run another VI which
reads the VI reference of the VI to call dynamically from that global
runs the corresponding VI dynamically
the dynamically called VI performs an AI task corresponding to the DAQmx task ID read from that global (it reads an analog value for instance from the
physical channel configured by that AI task)
Why all that? To prevent creating and destroying the VI reference for each call of the sub VI for speed. And to use the configured DAQmx channel for subsequent read tasks only if the subVI is called dynamically - if it is not, then the application will not see the DAQmx calls and therefore no broken arrow will occur if no DAQmx is installed on the machine.
Can somebody help me with this? Why can't I store and read out the reference to the sub VI to/from a global, and why is the AI task not valid when read out from the dynamically called sub VI? I am somewhat lost with all that...
Thanks in advance,
GabsUh - I am almost getting crazy with that
Kevin, that solution is the right one for programming an application. In that case everything will work fine. But during testing, it is more convenient to call all VIs from their front panels one after another. That's how I'm doing it for everything that needs to be exchanged between such VIs: store them either in a global or in a functional global variable. In that way the user can "play around" with the VIs without wiring them together in a main VI. Therefore, after some thinking I liked Davids idea with that daemon VI (I solved that by adding a boolean in the initialization VI to choose if that daemon is necessary - during testing phase - or not - when using the VIs in a main application). BUT:
David: It does not work!!! I have exactly done what you proposed and this daemon VI is really running, having a True/False frame with a constant of False wired to the selector and holding both the functional global and the dynamically to call VI in the True frame. In that way, after initialization is finished, both VIs are still running but idle. Anyway, when I read back the value of the reference or the DAQmx task, it is invalid again!
That really costs just too much time. Does anybody have any idea what to do now? David, I was hoping that your suggestion would solve the problem, because it would be logical that it would - why then is LabVIEW destroying the reference and task anyway even if that daemon VI containing the functional global is still running???

Dynamic call of a static method of an static attribute
Hi all,
is it possible to call dynamically a static method of a static attribute of a class.
The statement without dynamic call would look like this:
cl_test_class=>static_attribute=>static_method( ).
I would like to do it like this:
('CL_TEST_CLASS')=>static_attribute=>static_method( ).
Netiher the one nor the other way works for me - I'm getting the error "The notation used is reserved for business object classes".
Regards, StefanI guess, it is not possible to call method using the short form (parameters in brackets) is not possible in Dynamic Access. You may need to get the attribute first and then call the method.

Upgrade : Issue with Specical character being used in 4.6C ( Dynamic calls)
Hi ,
We are working on Upgrade from 4.6C to ECC6.0 . in SPAU phase we are facing an issue :
When we are trying to see the variants from the program, it says that the program contains Syntax Error
"In Unicode programs, the "&" character can not appear in names as it does here in the name 'op&xv0' "
The 'op&xv0' is a form. we tried changing the form name, but couldnt get the PERFORM stmt for the form and it might be a dynamic call. what can we do for this type of programs?
Please also suggest how we can identify the places where that particular Subroutine is being called.
Thanks & Regds
TejaThis is probably an operation defined in Tcode PE04. You can change the operation subroutine name and then modify the code accordingly in the report.
Go to PE04 and put in operation name, suposedly &xv0.
Instead of using standard name suggested by SAP use custom name (for example opYvx0) and then change in the report as well and it should be ok. -
How to dynamically call image in PDF for Acrobat ver 8.1 onwards?
Hi Experts,
I am using Web Dynpro Java. My requirement is to call the images dynamically on a PDF form. There are no of company code. I have to call different logos for different company codes/
We are now using Acrobat 8.1.1. Please refer following thread.
http://kb2.adobe.com/cps/405/kb405270.html
From Acrobat 8.*, we have to use some different method for dynamically calling the images. Earlier we were using the concept mentioned below to dynamically call images.
However this method is not applicable for Acrobat Reader 8.* onwards due to security reasons.
Click on the Layout tab and choose None for the Caption position.
u2022 Click on the Object, then the Binding tab and choose None for Default Binding.
u2022 Click on the Field tab, enter $record.SapOnlineShopUrl for the URL entry, and select Use Image Size for the Sizing field.
u2022 Click on the script editor and enter the following FormCalc script statement, which enables the dynamic integration of the image. Show: initialize Script: this.value.image.href = xfa.resolveNode(this.value.image.href).value; Language: FormCalc Run At: Client
write following code in wddoinit
try { String url = WDURLGenerator.getAbsoluteWebResourceURL( wdComponentAPI.getDeployableObjectPart(), "sap_online_shop.jpg"); wdContext.currentDataSourceElement().setSapOnlineShopUrl(url); } catch(Exception e) { throw new WDRuntimeException(e); }
Please let me know what is the alternate method for Adope ver 8.1.1
Regards,
GaryHi Gary,
First you upload the image in SAP through se78.then write the below code in your adobe form interface.
data : v_object type TDOBJECTGR value 'GRAPHICS',
v_id type TDIDGR value 'BMAP',
v_btype type TDBTYPE value 'BCOL',
V_FIELD TYPE XSTRING.
V_NAME = 'ZW_DEVMAN_LOGO'.
CALL METHOD cl_ssf_xsf_utilities=>get_bds_graphic_as_bmp
EXPORTING
p_object = v_object " 'GRAPHICS'
p_name = v_name " Name of the logo as in se78
p_id = v_id " 'BMAP'
p_btype = v_btype " 'BCOL' ( whether the image is in color or black and white )
RECEIVING
p_bmp = v_field
EXCEPTIONS
not_found = 1
internal_error = 2
OTHERS = 3.
g_logo = v_field.
Declare g_logo as xstring in global data.
In context of the form make one graphic element with field g_logo and mime type BMP.It will work.

Unexpected delay when dynamically called VI closes
LV10.0 / WXP
A VI is called dynamically by Run VI Method (Wait Until Done = FALSE, Auto Dispose Ref = TRUE).
Queues are used to exchange data with the main VI.
When this VI closes ("stop" message from the main VI), LabVIEW hangs for about 25 seconds (!) with one of the CPUs of the dual core machine at 100%.
Has anyone else encountered this strange behaviour ? Any ideas ?
Many thanks in advance
Solved!
Go to Solution.Norbert B a écrit :
Can you give us a small picture of the way you are calling and releasing the subVIs?
As mentionned in my first message : Run VI Method (Wait Until Done = FALSE, Auto Dispose Ref = TRUE) is used to call the VIs.
Release : after reception of a "close" message (queue), the dynamic VIs terminate their execution
If called with Auto Dispose Ref = FALSE, the freeze appears when Close Reference is executed in the calling VI (after reception of a "I'm closing" message from the dynamic called VI).
If loading the VI takes only a short time but unloading takes long, it seems to me that those subVIs allocate many new handles/memory spaces during runtime. Is that the case?
As mentionned in a previous message : The memory usage changes from about 687 to 676 MB when the four
instances are closed. The number of handles decreases from about 272k to
61k.
This sounds like the whole application freezes for the time being. Is it a single loop architecture?
No. It is a rather big application with several VIs running independently and exchanging data through queues.
In addition: You call those subVIs dynamical with reentrant execution (at least some of them). So they should run in parallel.
Yes, they run in parallel.
Did you configure different preferred execution systems for your different subVIs?
Yes, I have tried several combinations and also changed the Priority. I also tried to replace the While Loop of the VI which communicates with the PLC by a Timed Loop in order to specify the processor. Unfortunately all my trials ended without any succes.
Did you check for reference leaks using the Execution Trace Toolkit?
Yes. There are none.
Norbert
Thank you very much for your help -
How to check if internal table exists in dynamical called subroutine ?
Hi,
in a dynamically called subroutine i'm using a internal table, but in some calls this table is not exist.
How can i check in the code whether the internal table exist or not ?
regards,
HansIn Horst Keller's blog /people/horst.keller/blog/2005/05/27/abap-geek-10--everything-functions-150-but-how my issue is talked about :
All other parameters are handled in a way as they were declared as global data objects in the top include of the function group, that can be used only during the execution of the function module: They are visible throughout the function group but you can access them only while the function module is active. If you access such a parameter and the respective function module is not executed, you get the runtime error GETWA_NOT_ASSIGNED (Why? Well, technically thos guys are represented via field symbols which are valid only during the runtime of the function module).
The code is in SD pricing. Sometimes the code is called from function module PRICING_BUILD_XKOMV or PRICING_SUBSCREEN_PBO where TKOMV is defined as globalized parameter.
And sometimes it is called from function module PRCING_CHECK where TKOMV is NOT defined as parameter.
In the call of last function the dump occures on the ASSIGN statement :
data: ls_tkomv like line of tkomv,
lv_tablename(30) type c value 'TKOMV[]'.
field-symbols: <lfs> type any table.
assign (lv_tablename) to <lfs>.
if <lfs> is assigned.
Any suggestions to solve the issue ?

Hi!
I am writing a script where we are trying to use dynamic call types based on the inputs from a database look up. Basically the call is comes into the script and a database lookup is done on the AW to determine which call type is used. Later on we use a menu script and change the call type. Once the system has allocated a precision queue we need to collect some queue stats. How do we do this? The format for collecting a stats is PQ.<preciscion queue name>.CallsInQ. How du you replace the precision queue name with a variable that is then evalutated.
PeterYour best best is to keep the call type name in a PV, then just do PV.CallsinQ.

The following sample report <b>ZUS_SDN_TWO_ALV_GRIDS_8</b> shows how to solve your problem. Please note that for the sake of simplicity I replaced the tree containing the structure names with an ALV list. However, the switch between the different structures is triggered by the <b>DOUBLE_CLICK</b> event.
I like to add that the integration of the first displayed ALV list (DD02L) into GT_OUTTAB is not really elegant. In addition, with <b>$TMP</b> I marked a problematic part of the coding with respect to your requirement to have the right layout for each displayed ALV list:
If you have a <b>fixed </b>assignment of <i>tabname -> 4-digit handle</i> then it is ok. I my sample report the layouts only work if you select the tabnames in the very same order.
Before showing the entire coding I describe crucial parts of the coding:
[code]TYPES: BEGIN OF ty_s_outtab.
TYPES: tabname TYPE tabname.
TYPES: layout TYPE lvc_s_layo.
TYPES: variant TYPE disvariant.
TYPES: fcat TYPE lvc_t_fcat.
TYPES: data TYPE REF TO data.
TYPES: END OF ty_s_outtab.[/code]
Every time a new structure is selected the corresponding ALV data are stored as new record in GT_OUTTAB which is of line type TY_S_OUTTAB.
[code] READ TABLE gt_outtab INTO gs_outtab INDEX 2.
ASSIGN gs_outtab-fcat TO <gt_fcat>.
ASSIGN gs_outtab-data->* TO <gt_outtab>.[/code]
Since the ALV list data and the fieldcatalog are fully dynamic I use global field-symbols for these data.

The second ALV list which displays the table records is always newly displayed in the PBO module.
In the event handler method <b>HANDLE_DOUBLE_CLICK</b> we need to do two things:
- store the current fieldcatalog back to GT_OUTTAB
- store the name of the new selected table/structure -> trigger PAI
In routine <b>HANDLE_DB_CLICK</b> we create a new entry for GT_OUTTAB if it does not yet exist. Next we select this entry and display it again as second ALV list.

A colleague of mine has made a Matlab .m file that I should call in from LabVIEW. I have imported the function into a Matlab script node. I haven installed Matlab on my PC and therefore i get a licence error. Before I ask my boss for a matlab licence i will ask this forum if there is another way. The Matlab function is still under development and will change a number of times. I could be nice if I didn't have to import the function every time the .m file changes
1. Could I use a MathScript node instead? Or is there another way for importing or calling that function without a Matlab Licence?
2. Is it possible to dynamically call the Matlab Script node/ MathScript node eg via a propertynode or another method instead of importing the function?I know the Model Interface Toolkit has some options for Matlab but I think that is only for compiled Matlab models.
