Running external *.dll's on NI CVS-1450

I have yet to install and use the NI CVS-1450. The hardware is available, but the VI's and code have yet to be fully developed. Before I seek permission from the network security guys to install hardware and software, I'd like to know if my end goal is feasible.
I believe in Labview on my desktop I can call externall code libraries written in C, *.dll's, and use them in an integrated way with the rest of my VI.
Is it possible to do the same exact thing with the CVS-1450? Having no experience with the 1450, my question may not be worded correctly. Is it possible to upload the C *.dll's on the 1450 and have the Labview routine running on the 1450 call those *.dll's?
All feedback appreciated.

Apologies, I believe this post answers my question:Can I use external code on CVS 1450 with LabView RT 7.1?

What causes memory use of my program increase? (Write to Spreadsheet? Running in LV environment? External dlls? Waveform graphs?)

Hi
I have attached a plot for the discussion here..
I am monitoring the memory usage by my VI thru calling a window's dll to keep checking that (Many thanks to Matt).
I saw raising slopes and flat (wow! First time I catch this, that's what I am expecting)
I am thinking where could there be a reason for memory growing up!
What I did:-
1. Mostly use queues (all limited # of elements) for parameters delivery between loops and between subVIs
2. I close Obtained queue ref. every time I finish with it (only leaving a few keeping alive so they won't be killed)
3. For all arrays I initialized with a fixed size array constant and do all jobs with Replace subset, Index Array and that In-place block.
Above are measures I intended to use to save memory.
However for a few points I think there might cause a memory grows, and I wish that someone can share with me your experience or give me an answer...
1. Write to spread file:-- I keep using this to log data, events into harddisk, in my use I always append new logs/data to the existing file, however I keep doing it all the time throughout the run-time.
2. Running my program in LV.exe -- I havn't compiled it yet. However when I was taking the plot's data, my PC is left with no one using it.
3. There is a couple of external dlls running -- however it sounds to me from other's view point, external dll's resource doesn't count into Labview.exe. Since I am monitoring Labview's memory use, that couldn't be a source of the raising I see from this plot, right?
4. Waveform graphs -- I am not sure whether this can be a problem. Everytime I feed data into a waveform control, I initialized a constant array and then replace elements into it, I don't think my data source is casuing any problem.
Can someone comment on my above descriptions of my program?

Write to spreadsheet file is a high level VI that opens and closes the file with every call. I would recommend to open the file once at the start of the programs, then append using lowlevel functions. Close the file after the program is done.
Have you done any profiling to see which subVIs shows the bulk of the memory use?
You might also turn off debugging to see if it makes a difference. Don't open the front panel of subVIs (and avoid functions that force the front panel to be in memory) unless they need to show something important to the user.
It would really help if we could see some actual code. Can you strip it down to the essentials that still show the problem?

HELP! RETURN CLOB from External DLL

Hi
I am working on an External DLL using OCI. Basically, PL/SQL
calls an
External DLL to process the data and then returns LOB back to
the PL/SQL
procedure. Inside the DLL, I created a Temporary lob to process
the data.
The error is prompted from PL/SQL:
SQL> exec isdb.test_clob;
Before original length=10
ORA-24805: LOB type mismatch
ORA-06512: at "ISDBSVR.ISDB", line 24
ORA-06512: at "ISDBSVR.ISDB", line 29
ORA-06512: at line 1
So far I know that error is caused by the return from PLS_CLOB
is not clob.
"After_original := PLS_CLOB(before_original); {you will see more
code in the
below}" However inside the DLL, I have defined OCIClobLocator
and
OCI_TEMP_CLOB to carry the CLOB data.
I have found the following observations:
1. If I change everything to blob, it works fine. (such as
OCILobLocator,
OCI_TEMP_CLOB and all variables in PL/SQL)
2. If I run the same DLL and PL/SQL in 9i, it works fine (clob
too)
I guess it would be a bug for clob, please help to check thanks

LabView user-event from external dll source

Hi!
I'm dealing with the following issue:
I use a CAN sniffer device, wich sends data over USB to a PC. The main goal is to create a vi that can process the incoming data. I already have a vi wich works with polling mechanism. It calls external DLL functions with the "Call library function node". The main problem is the polling mechanism.
I would like to recreate this vi so that it would work event-driven. I have an other application, written in C++, that does the same thing, and it gets interrupts from a DLL, when a new data is available in the input buffer.
The callback mechanism is implemented in the DLL.
In LabView I would like to do tha same thing. There is the "event case structure", but there is no option for defining such user-events, that i would prefer.
I have found a similar topic, there the solution is "occurrences". The occurrence is called from a DLL, too. But this solution uses the "waiting for occurrence to set", that is an endless-loop-like thing.
The other thing I've found is the ActiveX and .NET events. I don't know, probably that is the solution.
Anyway: is there a possibility to create such events, that can be generated from a simple external DLL and can be handled by "event case structure"? How should I do this?
Or how NI does this? I mean that NIs DAQ cards must use some similar methods for data processing. Is there some tutorial or support about it?
Thank you for your answer!

Hi Wiebe, From your answer i have a doubt that What it exactly means "If the dll is used from within LabVIEW". Also i want to know Is there any way to access the functuions defined in the .SYS file in Labview Environment. Regards,Jagan Can you be a litte more specific with your first sentence. I have no good idea what you mean. A .sys driver is usually a kernel device driver. This driver has to be started and run in the kernel subsystem which LabVIEW can not access directly. Such a driver is initialized using the CreateFile() Windows API. The returned handle is then used with other API functions such as ReadFile(), WriteWile(), DeviceIoControl(), and finally CloseHandle().Theoretically you could call all this APIs directly from within LabVIEW using the Call Library Node. In practice you do not want to do this even for fairly simple kernel drivers since the parameters for those APIs do get fairly complex in most cases, and you usually do also want to have some sort of asynchronous operation using events or such to make the driver access user friendly. All these things are most easily handled in a user space DLL written in C that exports a more LabVIEW friendly API that you can then import into LabVIEW using the Call Library Node. Usually most kernel device drivers do come with a accompagning user space DLL already, as this is the only sensible way of accessing such a driver. So you can usually look for the documentation of that user space DLL API and go from there trying to import that into LabVIEW using the Call Library Node. Even then it may not be easy at all if that API uses complicated function parameters and even completely impossible if it uses callbacks or such, requiring you to write a so called wrapper DLL that translates between the native API and a more LabVIEW friendly API. You don't have to believe me but I can guarantee you that if writing such a user space DLL or wrapper DLL is beyond your capabilities, trying to go directly about accessing the Windows APIs in LabVIEW to access a kernel device driver is going to make you squirm in real pain. And those knowing how to write such a DLL would never even consider spending the time to try to access a kernel device driver directly from LabVIEW. Rolf Kalbermatter

Compiling own app with -X02 makes external dll core dump.

Hello,
I have a C++ app that calls a function w/in an external shared library. The external dll does not have debug symbols and is probably optimized. When my app is compiled with -xO2 or higher, I get a core dump (no mapping at the fault address) deep within the external dll. When I am compiling my app with -xO1 or with debug info, I do not get the core dump within the external dll.
My questions are:
1. Does this mean that there is a bug w/in my code or within the external dll's code?
2. If not error in either, is there any way to overcome this core dump without lowering the level of optimization (and thus slowing down the app)
Here is a stack trace I got by attaching dbx to my app:

From the symptoms you describe, it is possible that the shared library contains a bug, but it is more likely that the problem is in your code, passing bad data to the shared library.
The problem might be a compiler bug, but I think an error in your code is more likely.
For example, your code as written might have undefined behavior that works by accident when compiling without optimizing, but fails when the compiler improves the runtime code.
Some examples:
1. A classic MT programming error is failing to declare a variable volatile when it is shared by more than one thread. In each thread, the compiler assumes it can remember the value of the variable and not reload it between references.
2. "x = ++x + b;" Modifying a variable twice in an expression withtout sequence points has undefined behavior -- compiler optimization can affect the result.
3." foo(x, x+=3);" the order of evaluation of function arguments is unspecified, so the actual values passed to foo could depend on optimization.
With C++ 5.5, you get some warnings from system headers that you can't do anything about, which I suspect is why you have disabled some warnings. Unfortunately, you might be disabling warnings that you need to see. That is, some of the disabled warnings could point to invalid code that results in the program crash.
I suggest using w instead of w2 (to avoid uninteresting warnings), and fix your code to eliminate the warnings you get.
In the current compiler, C++ 5.7 in Sun Studio 10, we have made some adjustments to warnings to make w and w2 more useful. You should consider upgrading.You can get a 60-day free trial version here:

Wrapper for invoking external DLL-function

I want to run a Host-Command (e.g. rwrun60 report=xyz.rdf batch=yes) invoked by a trigger that fires when a new record is inserted.
I wrote a DLL which has an exported function that accepts a commandline (with parameters) and invokes the command via ShellExecute.
The problem is, that when i invoke the PL/SQL-wrapper, the DLL-function is properly run, but the program i want to run is only visible in the taskmanager(NT) and does nothing.
So what i need is a correct wrapper for the function:
DLL-function: OExecSysCmd(cmdLine *char)
Wrapper:
PROCEDURE OExecSysCmd(p_SysCmd in char)
IS EXTERNAL
NAME "OExecSysCmd"
LIBRARY demolib;
Thanks in advance

Hi Russ,
with "invoke an external dll" I mean that I have to wite a log file to register my fdk client events and to do this I have to use an external dll wich exposes some functions to write to a common log file. I have imported the external dll in my client project and at the beginning of client code I have included the dll header file:
#include "LogDll.h"
Then I've tried to invoke a LogDll function (not within F_ApiInitialize (), but in a custom dialog box event):
int retval=LogDllFunction();
The code compiles, but if I start FM, I receive the message error. If I comment the line above, FM and my client start normally.
Thanks,
Stefano

Running External Programmes in XI

I need to run external programs like C or C++ Dlls or Java programs from XI and pass parameters to the same
Does anyone has idea about how to run or trigger external programs efficiently from XI , other than running through the mappings.
regards
karthik

I get an "app is not defined" error when I tried your method, so I guess you need more code than just what you supplied in your example.
In any case this works fine and I don't see a reason to do it another way.

I would like to convert a matlab file into a .dll and use it in LabVIEW. However, when I run the .dll in LabVIEW I get an error stating "... Procedure not found". What could this be? Can anyone help me...

I wish to convert my Matlab files into .dll's so that I can use them in LabVIEW. I am using 'mcc' and 'mbuild' of Matlab to convert my .m files into .c and .dll.
When I try to run the .dll's in LabVIEW, I get an error message in a modal window stating some required .dll or procedure is not found.
How should I resolve this issue. Should I add any other Matlab .dll's in course of making my .dll?
Please help in solving this issue... Thankyou very much.

I have the same question,I don't know how to use the matlab DLL file in labview,
I hope someone can descripe the procedure in detail.

When opening a PDF in IE 10 with Enhanced Protection Mode it displays "This website wants to run acropdf.dll"

I am running my application which requires JRE on Internet Explorer 10. Since the IE need to run in 64 bit mode, we have enabled the "Enhanced Protection Mode" in Security option of Internet Options in Advanced tab. But my application also opens
up PDF in the browser, when the page with PDF is invoked it displays "The webpage wants to run 'AcroPDF.dll'. If you trust this site, you can disable Enhanced Protection Mode for this site to run the control.(Disable)(Always Ignore)". And on
clicking any option the PDF is not displayed.
We would not be able to disable the Enhanced Protection Mode as the 64 Bit JRE would not be invoked for other part of the application.
Please let me know how to resolve this issue.

... and/or
Configure Adobe Reader to not use a Web Browser to open PDF documents... (see the Adobe.com for admx files to apply this setting by group policy) (
http://forums.adobe.com/thread/392489 )
Start>Adobe Reader>Edit>Preferences>Internet>uncheck "Display PDF in browser"
It seems that Adobe have recently changed the location of that setting in Adobe Reader (at least on 11.0.4). They've now hidden it under Edit > Accessibility > Setup Assistant > Then on page 5 of 5, there's a tick box to toggle 'Display PDF
documents in the Web Browser'.
However, it doesn't work like it used to though, as it won't just open a PDF in Adobe Reader instead of the browser. It will instead ask to disable Enhanced Protected Mode to run acroPDF.dll.
And if you try disabling the Adobe PDF reader add-on in Manage Add-ons to try and force it to open in Reader, then when you visit a PDF link, you just get the same blank page (shown below) with the black crossed out circle in the top left, but without the
message bar at the bottom of the window. The only way to open the PDF is to either turn off Enhanced Protected Mode and allow acroPDF.dll to run or if there's an original link to the PDF, right click and select 'save-as'.
I think it's about time Adobe released an x64 PDF viewer... Or at least there should be an open/save dialogue box in IE.
If you've got Reader 11.0.4 installed, you can try it for yourself with this PDF link:
http://helpx.adobe.com/pdf/adobe_reader_reference.pdf
(The below screenshot is with 'Display PDF documents in the Web Browser' UN-ticked in Adobe Reader settings, so it should open in Reader instead. But it doesn't. And with the Reader add-on disabled you get the same page, but without the
message at the bottom.)

How to load external DLLs with C++ interface in TestStand?

Hi,
Can you please let me know how would I load external DLLs with C++ interface in TestStand?
Regards.

TestStand 3.x can only call static class C++ methods. TestStand cannot call methods on a C++ object because TestStand does not know how to enstantiate the C++ object. In TestStand 3.x, there is a online help topic called "Exporting Class Methods and Functions in Visual Studio .NET".

Run External Application

Does anyone know the best way to connect to an external (non-Oracle) application via SQL or PL/SQL?? I have to run external applications such as MS Word from within an Oracle application. There are several applications which may be used, so I plan to start with a page of options with selection of an option connecting to the external application. Any proven options will be considered.

This may be be very hard to accomplish...
If users are accessing an HTMLDB application, they persumably using a browser. Browsers, by design, aren't allowed to spawn external applications on the client machine-- imagine what would happen if I could put up a web site that opened an arbitrary application on your desktop. In theory, you could probably write an ActiveX/ Java component that could be embedded on pages from HTMLDB and will, with the right security settings, open up application windows. This would be a very complex development, deployment, and maintenance problem, though.
Perhaps if you explain why you want to spawn these applications, we could provide more assistance. It may be as simple as providing a link to a .XLS file stored in the database. When the user clicks on that and downloads the file, the server can identify the content-type of the file and the browser will open the file in whatever application is registered to support that file type.

How to use external DLLs in InDesign server plugin

Hi,
I am working on a project, which is having dependency on libxml2 library. I compiled the code on 64 bit Windows platform and using InDesign server 64 bit version. I put the required DLLs in Adobe InDesign CS6 Server x64 folder(with other DLLs). But now my plugin is not loading in server and also not throwing any error message on command prompt.
If I remove the libxml2's method call, then plugin is loading successfully.
Is there any other way to use external DLL or I am missing something?
Thanks & Regards,
Harsh

Hi Sidharth,
If you are using web dynpro DC perspective then you need to follow the following points to use the external jar files in it.
1. Create a external library project.
2. copy the external jars in the library folder os the projects.
3.) Select all the jars from the u201CLibrariesu201D folder, Right click and then select Development Component and click on Add to Public Part
4.Select the first Radio Button (Provides an API)and give some nameto it.
5. Repeat the step no 3 but now select the second radio button other than as selected in step no 4.
6. Now build your lirary DC.
7. Now create a j2ee DC project.
8. ) Expand the node DC Definition and Right Click on Used DC. Select Add Used DC.
9. Select the External Library DC with build time dependency.
10.Right click on the J2EE DC and then select Development Component followed by Build
11. Right click on the J2EE DC and then select Development Component followed by Deploy
now you can use both the libary DC and the j2ee DC in your web dynpro DC as used DC.
But if you have created a web dynpro project only(but not DC) than you can directly add the external jars in java build path
hope this will help
regards

You have media fetch error,the URL being formed is below:
file://../MediaFiles/en-us/app/Welcome.wav
should be something like http://x.x.x.x/en-us/app/welcome.wav
also please share your full CVP logs for the call.
it is always annoying to see b2b user agent is not configured, so please configure ringtone and error label to sent to proper VXML gateway.
